Description

  The present invention relates to a management system using an information code.

  At present, the use of information codes is diversified, and a technique for arranging photographs and drawings in the code area has also been proposed. For example, in the technique of Patent Document 1, an inversely converted bit string obtained by inversely converting a bit string that forms an area to be read as a single value in a two-dimensional code is obtained, and the inversely converted bit string is converted based on the format information of the two-dimensional code. By generating a two-dimensional code, a special two-dimensional code having a design area composed of a single gradation value is generated.

  However, the existing technology related to information codes including a design area has always been simply to represent the design in the information codes, and no consideration has been given to how such information codes should be managed.

And a communication unit 97 that functions as a communication interface for performing communication.

(Information code)
Next, the information code 100 used in the management system of FIG. 1 will be described with reference to FIGS. The example of FIG. 1 and the example of the right side of FIG. 5 are slightly different in the cell arrangement and the size of the specific pattern, but the basic idea is the same and has the same characteristics. The information code 100 shown in FIG. 1 and FIG. 5 is generated by, for example, the information code generation device 2 described above, and has a configuration in which cells 102 serving as units for displaying information are arranged inside a predetermined code area. It has become. In the information code 100 of FIGS. 1 and 5, the “code area” is a rectangular area that can include all of the plurality of dark cells arranged, and is the smallest square that includes all of the cells constituting the information code 100. It is a region or a rectangular region. Specifically, it is a minimum square area or rectangular area including all three position detection patterns (cutout symbols) 104. In the example of FIGS. 1 and 5, the plurality of cells 102 are configured by either a rectangular (for example, a square outer diameter) light (white) cell or a dark (black) cell, Within the code area, these cells 102 are arranged in a matrix around an empty area 110 described later. The light color cell and the dark color cell are not limited to the white cell and the black cell, respectively. When the dark color cell is configured with a predetermined lightness, the light color cell only needs to have a higher lightness. In the information code 100, a light or dark margin area is formed around the code area so as to surround the code area. In the examples of FIGS. A margin area (for example, another color having a lightness higher than that of a white or dark cell) is arranged adjacent to the periphery of the code area.

  The information code 100 includes data in a specific pattern area in which a specific pattern having a predetermined shape is arranged inside a rectangular code area (for example, a square shape or a rectangular shape), and a plurality of types of cells 102. A data recording area for recording and an error correction code recording area for recording an error correction code by a plurality of types of cells 102 are provided. As shown in FIGS. 1 and 5, the specific pattern of the information code 100 is, for example, a known predetermined model number of a QR code (registered trademark) (in the example of FIG. 5, a predetermined model number of a QR code standardized by JIS or the like). ), The position detection pattern (cutout symbol) 104 as the specific pattern is arranged at each of the three corners of the code area in the examples of FIGS. ing. Further, a timing pattern 106 and an alignment pattern 108 as specific patterns are also provided at predetermined positions in the predetermined model number. As described above, in the information code 100, a specific pattern (position detection pattern 104, timing pattern 106, alignment pattern 108 (not shown in FIG. 5)) having a predetermined shape is arranged at a predetermined position. . It should be noted that, within the code area, positions other than the empty area 110, which will be described later, are configured by such specific pattern areas, recording areas (areas consisting of either data recording areas or error correction code recording areas), and the like. Yes.

  The number of rows and columns of cells of the information code 100, the shape and position of a specific pattern, the position of format information, the codeword candidate position (address for specifying the arrangement order of codewords), etc. You may grasp. For example, a plurality of model numbers may be provided in the type of the information code 100. In this case, the number of rows and columns of cells, the shape and position of a specific pattern, the position of format information, and a code word are arranged for each model number. The candidate position (address) may be determined in advance. If the model number information for specifying the model number is arranged at a predetermined position (reserved area) in the code area, the reader device can determine the number of rows and columns of cells of the information code 100 based on the model number information. It becomes possible to grasp the shape and position of the specific pattern, the position of the format information, and the candidate position (address) of the code word. Note that the present invention is not limited to this method, and any other method may be used as long as the reader can grasp the method.

  Within the code area, the area other than the specific pattern area, data recording area, and error correction code recording area is an area where data is not recorded by the cell 102 and is not subject to error correction by the error correction code. A certain free area 110 is provided in a size larger than the size of the single cell 102. In the examples of FIGS. 1 and 5 and the like, the data recording area and the error correction code recording area are arranged in an annular and rectangular shape along the periphery of the code area, and the center of the code area (the center of the code area is defined). A free area 110 is formed in a predetermined area. The “area in which no data is recorded by the cell 102” means an area in which a code word such as a data code word and an error correction code word to be described later is not recorded, and an area in which format information is not recorded. To do. The “region not subject to error correction by the error correction code” means a region where error correction using the error correction code recorded in the error correction code recording region is not performed. Therefore, even if some information (additional information to be described later) is recorded in the empty area 110, error correction for the information is performed by the error correction code in the error correction code recording area existing around the empty area 110. Absent.

  In the following description, a configuration corresponding to the predetermined model number as shown in the right diagram of FIG. 5 is associated with another model number (Ver. Number) having a smaller size than the predetermined model number as illustrated in the left diagram of FIG. An example in which the position of each code word of the information code 100 in the right diagram of FIG. 5 and the position of each code word of the other code 120 in the left diagram of FIG. 5 are associated by the arrangement conversion table as shown in the lower diagram of FIG. Will be described as a representative example. In this example, the amount of data that can be stored in the other type code 120 in the left diagram of FIG. 5 can be expressed with the empty area 110 provided by the information code 100 as shown in the right diagram of FIG. Conversely, when the information code 100 shown in the right diagram of FIG. 5 is read, each code word of the information code 100 can be read as a code word of another type code 120 as shown in the left diagram of FIG. .

  In the right diagram of FIG. 5, each codeword area arranged around the empty area 110 is conceptually shown by a broken line frame or the like. An area (predetermined position 105) for recording format information is conceptually indicated by a predetermined type of hatching. In the right diagram of FIG. 5, in the area where the format information is recorded and the area where the code word is recorded, only the squares are shown, and the specific arrangement of light cells and dark cells is omitted. Further, in the example of the right diagram in FIG. 5, the interior of the empty area 110 (the central part of the code area) is also assigned to correspond to the cell arrangement, but the configuration of the empty area 110 is free, and FIG. It may be configured as described above, or may be other configurations.

  The format information (format information) is configured as shown in FIG. 6, for example, and is recorded at a predetermined position 105 (a predetermined type of hatching position) in the information code 100 with a specific format configuration. This format information includes correction level information for specifying an error correction level and mask number information for specifying a mask number. The correction level information is information for specifying an error correction level used in the information code 100, and corresponds to an error correction level used in the other type code 120 in the case of being converted into the other type code 120 and read, for example. The mask number is information for specifying which mask type is the mask applied to the codeword area of the information code 100 (area in which the data codeword and error correction codeword are recorded).

  As shown in FIG. 6, the format information is recorded in a state reflecting a predetermined type of mask pattern (specific mask), and the format information is identified by identifying the mask type of the format information in the same manner as a known QR code. 5 It is possible to detect a specific code type (type provided with a free area 110) as shown in the right figure. For example, when the model 1 is configured as a QR code of a known standard, data (cell array) expressed when the model 1 mask is applied to the format information as shown in FIG. 6 is recorded at a predetermined position. However, when configured as the model 2, data (cell array) expressed when the model 2 mask is applied to the format information as shown in FIG. 6 is recorded at a predetermined position. . On the other hand, in the information code 100 of this embodiment shown in FIG. 5 (special type code having a free area 110), a specific mask of a different type from the models 1 and 2 (FIG. 6) for the format information as shown in FIG. Then, the data (cell array) expressed when the frame QR is used is recorded at a predetermined position 105. Then, in any of the types 1 and 2 of the known standard and the type of the information code 100, a check digit corresponding to the correction level (correction level information) and mask number (mask number information) to be recorded is added. Format information is configured, on which various types of masks can be applied. Specifically, mask processing is performed by a known method using various types of mask patterns, and the bit pattern after the mask processing is recorded at a predetermined position 105. Therefore, when the format information is recorded at the predetermined position 105 after applying a specific mask (example for frame QR in FIG. 6) to the format information like the information code 100, the information recorded at the predetermined position 105 in this way is recorded. If the mask process is canceled and decoded based on the specific mask, the check digit is matched, so that the type of the information code 100 can be specified. On the contrary, even if the data at the predetermined position 105 of the information code 100 is removed based on the masks of the model 1 and model 2, the check digit does not match. be able to.

  In this information code 100, after detecting a specific pattern (position detection pattern 104, etc.) and specifying the code area, code direction, and each cell position in the same manner as the known QR code, the same as the known QR code. By decoding the predetermined position 105 where the format information is recorded by the method, it is possible to identify the type of the information code 100 (special type having the empty area 110) according to the type of the mask that has been successfully decoded. Then, the error correction level used in the information code 100 can be specified by the decoded format information, and applied to the code word area of the information code 100 (the area where the data code word and the error correction code word are recorded by the cell). It is possible to specify the mask type.

  The content recorded in the information code 100 has, for example, a configuration as shown in FIG. 3, header data (frame QR header) is set at the beginning of the data array, and input data (decryption target data) after the header data. ) Continues. In the example of FIG. 3, input data (data to be decoded) is compressed by, for example, a known method and converted into a data word (data code word). However, such compression may not be performed. The header data used in the information code 100 is also referred to as a “frame QR header” in the following description. Further, in this specification, such an area for recording data words (data code words) of header data and input data (data to be decoded) and an area for recording the above-described format information correspond to “data recording areas”. To do. Further, in the example of FIG. 3, as header data (frame QR header), another type code 120 (a code type used for decoding the information code 100, which will be described later), and the information code 100 according to the arrangement conversion table (FIG. 5). Information (identified as Ver. Number in FIG. 3) and identification information that can specify the format in the empty area are recorded. In the example of FIG. 3, as the header data, in addition to the type of other code (Ver. Number), it is specified that the format of the empty area 110 is the image format shown in FIG. 1, FIG. 5, FIG. Information (first information) and information that can specify the position of the image (image area position) in the empty area 110 (“image area position information” corresponding to the second information) are recorded. Among these, the information (first information) for specifying that the format of the empty area 110 is an image format corresponds to an example of “identification information” indicating the presence of the image area. The information (second information) that can specify the position of the image in the empty area (image area position) corresponds to an example of “position data” indicating the position of the image area in the code area.

  In the example of FIGS. 3 and 5, information that can specify the column position and row position of the image area 121 is recorded as image area position information (position data). More specifically, a combination of the upper left row position and column position of the image area 121 when the information code 100 configured in a rectangular shape as shown in FIG. 5 is divided into a plurality of rows and columns in a grid pattern, A combination of a row position and a column position in the lower right of the image area 121 is recorded as image area position information (position data). Here, the combination of the upper left row position and the column position of the image area 121 and the lower right row position and the column position of the image area 121 are used as the image area position information (position data). A combination of the row position and the column position at each of the four corners may be used as image area position information (position data). Further, the width of each row and each column when the information code 100 is divided in a lattice shape as shown in FIG. 5 corresponds to the width in the row direction and the width in the column direction of a single cell, respectively.

  An error correction code word (ECC word) that becomes an error correction code follows the input data (data word that is data to be decoded). In the information code 100, an area for recording the error correction code is an error correction code recording area. Note that a method for generating an error correction code (error correction code word) based on a data word (in the example of FIG. 3, header data and input data (data to be decoded)) is a known two-dimensional code (such as a QR code). A method defined in the standard can be used. For example, as a method for generating an error correction codeword based on a data word (data codeword), an error correction codeword generation method (JISX0510: 2004, 8.5 error correction) defined in JISX0510: 2004 is used. be able to. Note that the method of generating the error correction codeword is not limited to this, and various known methods can be used.

  Further, in the information code 100, each data word (data code word) representing the data to be decoded (data code word) and an error correction code word are arranged in the code area based on predetermined arrangement position information. In this configuration, as shown in FIG. 5, the arrangement candidate positions of the respective code words are determined in advance within the code area of the information code 100, and a number (address) is assigned to each arrangement candidate position. The arrangement position information is information for specifying which arrangement candidate position each code word constituting the recording contents shown in FIG. 3 should be arranged. In the example of the right diagram in FIG. 5, the arrangement candidate positions Nos. 1 to 25 are schematically illustrated. In each arrangement candidate position, the first and last bit portions are numbered and clearly shown. In the right diagram of FIG. 5, the arrangement candidate positions after the 26th are omitted.

  Specifically, in the model number of the other type code 120 (known QR code) (the model number of the other type code 120 specified by the header data shown in FIG. 3), the code word in each order is included in the other type code 120. Whether or not to be arranged at a position is determined in advance by a known standard or the like, and when the other-type code 120 is decoded, the code words in each order are decoded based on the arrangement determined in this way. For example, in the example of the other type code 120 shown in the left diagram of FIG. 5, the 0th code word is arranged at the lower right, the first code word is arranged thereon, and the second code word is arranged thereon. The arrangement position of each code word is determined in advance. Therefore, when decoding this other type code 120, the 0th code word, the 1st code word, the 2nd code word, the 3rd code word, etc. based on the arrangement determined in this way. It will be deciphered in order.

  On the other hand, in the arrangement position information (arrangement conversion table) shown in FIG. 5, the numbers of the arrangement positions (arrangement positions of the code words in each order) determined in advance by the other-type code 120 in this way are pre- Each number is associated with a number of a determined candidate position (position candidate position of each code word). Specifically, “the arrangement position of the first code word in the other type code 120 corresponds to the first arrangement candidate position of the information code 100”, “the arrangement position of the second code word in the other type code 120 is information. Information such as “corresponding to the second arrangement candidate position of the code 100” and “the arrangement position of the third code word in the other type code 120 corresponds to the third arrangement candidate position of the information code 100” is, for example, table data Each code word is recorded, and the arrangement position of each numbered code word in the other type code 120 is associated with each arrangement candidate position of the information code 100. Thus, when the information code 100 is decoded, the code word (code word at each address) in each placement candidate position in the code area is associated with the placement position information (placement conversion table). The other-type code 120 may be rearranged at each arrangement position, and the other-type code 120 rearranged in this way may be decoded by a known method. For example, when the information code 100 is decoded using the arrangement conversion table shown in the lower diagram of FIG. 5, the code word at the first arrangement candidate position of the information code 100 is changed to the arrangement position of the first code word in the other type code 120. The code word at the second placement candidate position of the information code 100 is placed at the placement position of the second code word in the other code 120, and the code word at the Nth placement candidate position of the information code 100 is placed in the other kind. The code 120 is rearranged in such a manner as to be arranged at the arrangement position of the M-th code word associated with the N-th arrangement candidate position, and the other type code (re-arranged in this way) QR code) may be decoded by a known method. As for the above-described arrangement position information (arrangement conversion table), data (common arrangement) common to the information code generation apparatus 2 that generates the information code 100 and the information code reading apparatus (for example, the management apparatus 90) that reads the information code 100 is used. It is desirable that a conversion table is provided.

(Information code generation and storage processing)
Next, information code generation and storage processing will be described with reference to FIGS. First, an overview of information code generation and storage processing will be described with reference to FIG.

  The example shown in FIG. 9 shows the flow of processing when, for example, the user operates the generating device 2 at various places to take pictures and generates and stores information codes incorporating the pictures. The process shown in FIG. 9 is started, for example, by performing a predetermined operation in the generation device 2, and first, a photograph is taken by the imaging unit 8 (S100). Note that FIG. 13A shows a state in which such a photograph is taken, for example, on a trip. Thereafter, a keyword input by the user is accepted (S101). FIG. 13B shows an example of such keyword input, and schematically illustrates an example of inputting a keyword related to the captured image obtained in FIG. Thereafter, the information code 100 including the captured image obtained in S100 and the keyword obtained in S101 is generated (S102), and the information code 100 is stored (S103). The generation process in S102 and the storage process in S103 will be described later.

  Here, the generation process in S102 will be described in detail. In the following, a case where the other type code 120 is a QR code (registered trademark) and the information code 100 has a specific pattern similar to the QR code as shown in FIG. 5 will be described as an example. In this example, the information code 100 having the empty area 110 is also referred to as “frame QR”.

  In this process, first, data to be encoded (data to be decoded), attribute data, and code type data (information code 100 is generated, or a general two-dimensional code (for example, a general QR code) is generated. (S1) is confirmed. The data to be encoded (data to be decoded) includes the keyword input in S101. In addition, when the photography in S100 is successful, it is designated to generate the information code 100 including the free area 110, and the captured image obtained by the photography in S100 is an image to be incorporated into the free area 110. Confirmed as a candidate. Further, for example, when the shooting at S100 is not successful or when the shooting at S100 is omitted, it is designated to generate a general two-dimensional code.

  After acquiring the data in S1, a method for compressing the acquired data is determined by a known method (S2), and the compressed data (decoded data) is expressed by a plurality of data words (data code words). (S3). Then, after S3, it is determined whether or not the code type data acquired in S1 is the type (frame QR) of the information code 100 having the free space 110. If the code type data acquired in S1 is the type of the information code 100 having the free area 110 (frame QR), the process proceeds to Yes in S4, and the type of the information code 100 having the free area 110 (frame QR). ) Is generated and set at the head of the data array including a plurality of data words as shown in FIG. 3 (S5). In the header data of FIG. 3, as described above, information (version number information etc.) that can specify the type (model number) of the other type code 120 shown in the right diagram of FIG. Information specifying the presence (first information) and information that can specify the image area in the empty area 110 (“image area position information” corresponding to the second information) are recorded. On the other hand, when the code type data acquired in S1 is not the type (frame QR) of the information code 100 having the free area 110 (data for selecting a general two-dimensional code (for example, model 1 or model 2 is selected). If (data), the process proceeds to No in S4.

  When the process proceeds to No in S4, an error correction code is generated by a known method based on the configuration of the data word (data code word) generated in S3, and a plurality of error correction words (error correction) representing the error correction code are generated. Codeword) is generated (S6). On the other hand, when proceeding from S4 to S5, an error correction code is generated by a known method based on the configuration of the final data word (a plurality of data code words representing header data and input data) generated in S3 and S5. Then, a plurality of error correction words (error correction code words) representing the error correction code are generated (S6).

  After S6, it is determined whether or not the code type data acquired in S1 is the type (frame QR) of the information code 100 having the free area 110 (S7), and the code type data acquired in S1 is If it is not the type (frame QR) of the information code 100 having the free area 110, the process proceeds to No in S7, and a two-dimensional code (for example, QR code) is generated by a known method. When the process proceeds to No in S7, the model number of the two-dimensional code having a size capable of storing the data word (data code word) generated in S3 and the error correction word (error correction code word) generated in S6 (in this example, In a plurality of standardized known QR code model numbers, a model number of a size that can store the data word generated in S3 and the error correction word generated in S6) is determined, and the arrangement predetermined by the model number is determined. According to the pattern, the data word generated in S3 and the error correction word generated in S6 are arranged (S9).

  On the other hand, if the code type data acquired in S1 is the type (frame QR) of the information code 100 having the free area 110, the process proceeds to Yes in S7, and the data word (data) generated in S3 and S5 (Code word), the error correction word (error correction code word) generated in S6, and the empty area, the model number of the information code 100 that can be stored is determined (S10). Note that the size of the empty area may be a predetermined fixed size, or may be designated by an input or the like by the user before S10. Further, the size of the empty area may be specified by the number of rows and the number of columns, or may be specified by information such as how many words it corresponds to, or how many cells it corresponds. In the example of FIGS. 5 and 8, for example, in a plurality of model numbers (sizes) determined in advance by the type of the information code 100, the data word (data code word) generated in S3 and S5 and the error correction generated in S6 A model number of a size that can store a word (error correction code word) and an empty area is determined. When a plurality of model numbers can be used in the type of the information code 100, the number of rows and the number of columns, the shape and layout of a specific pattern, the layout of format data, and the layout candidate position of each code word are provided for each model number. It should be determined. Also, in any model number, the arrangement candidate positions of the respective code words are determined in order from the outer circumference side as shown in the right diagram of FIG. 5 (for example, the arrangement candidate positions are set in a spiral shape from the outer circumference side to the inside). The placement candidate position of each code word is determined so that the placement candidate position with a smaller number is located outside, and a portion where the code word is not placed (that is, a portion that is not used) among the prepared placement candidate positions. If it uses, it becomes easy to ensure a large empty area | region by the center part. In addition, when there are a plurality of model numbers having a size capable of storing the data word (data code word) generated in S3 and S5, the error correction word (error correction code word) generated in S6, and the empty area, The smallest model number (size) may be determined from among them, or the user may be able to specify any model number (size) from among them. When the information code 100 is generated, a predetermined size (number of rows and columns), a specific pattern arrangement, and each arrangement position position of the codeword are used in the model number thus determined. The arrangement position of each code word is determined according to the above-described arrangement conversion table. In the following, an example in which the model number as shown in the right diagram of FIG. 5 is determined in S10 will be specifically described.

  After S10, the data word (data code word) generated in S3 and S5 and the error correction word (error correction code word) generated in S6 are arranged based on the arrangement position information (arrangement conversion table) described above. It will be. In the information code generation device 2, the above-described arrangement position information (arrangement conversion table) is stored in the storage unit 5, and in this arrangement conversion table, as described above, each arrangement position (each (Order position of code word) is associated with a predetermined candidate position (position candidate position of each code word) in information code 100, respectively. In the process of S11, the code words to be recorded (the data words (data code words) generated in S3 and S5 and the error correction words (error correction code words) generated in S6) are shown in the left of FIGS. Is represented by another code 120 (a two-dimensional code having a size smaller than that of the information code 100 and a size capable of storing the data word generated in S3 and S5 and the error correction word generated in S6). After specifying the arrangement position of each code word (code word in each order), the code word in each order is associated with the arrangement position of the code word in each order by arrangement position information (arrangement conversion table). It arrange | positions in each arrangement | positioning candidate position in the information code 100. FIG. For example, in the arrangement position information (arrangement conversion table) in FIG. 5, the arrangement position of the first code word in the other type code 120 is associated with the first arrangement candidate position of the information code 100. The first code word of the code words to be recorded (the data word generated in S3 and S5 and the error correction word generated in S6) is arranged at the first arrangement candidate position in the information code 100. In addition, since the second code word arrangement position in the other-type code 120 and the second arrangement candidate position of the information code 100 are associated with each other, the second code word in the code words to be recorded Is placed at the second candidate position in the information code 100. In this way, the arrangement position (an arrangement position of the Nth code word) in the other type code 120 in which the Nth code word is arranged in the codeword to be recorded and the Mth arrangement candidate position of the information code 100 are as follows. If they are associated, the Nth codeword among the codewords to be recorded is arranged at the Mth arrangement candidate position in the information code 100.

  That is, only the data word generated in S3 and S5 and the error correction word generated in S6 can be expressed by another type code 120 (configured as a known QR code) smaller than the information code 100. When the data word generated in S3, S5, the error correction word generated in S6, and the empty area 110 are stored, it must be expressed by the information code 100 having a larger size. Therefore, in the present embodiment, the data word generated in S3 and S5, the error correction word generated in S6, and the empty area 110 are represented by the information code 100 having a size larger than the other type code 120, and S3 and S5. The data word generated in step S6 and the error correction word generated in step S6 are stored in the arrangement of the code words when expressed by another type code 120 (known QR code) and the information code 100 having a size larger than this. In this case, the correspondence relationship with each arrangement of codewords can be specified by a predetermined arrangement conversion table.

  In this configuration, the “arrangement conversion table” as shown in FIG. 5 corresponds to an example of “arrangement position information for specifying each arrangement position when a plurality of data words expressing the data to be decoded are arranged in the code area”. The arrangement conversion table (arrangement position information) includes data words in each order when the data to be decoded is expressed by a plurality of data words, and each arrangement position in the code area of the data words in each order. Are configured as information determined in association with each other. The storage unit 5 corresponds to an example of an “arrangement position information recording unit” and functions to record data (arrangement position information) of such an arrangement conversion table.

  After S9 or S11, a mask pattern to be applied to the code word whose placement location has been determined in S9 or S11 is determined by a known predetermined method (for example, a known method used in QR code), and the determined mask. Masking is performed by a known mask processing method so that the pattern is reflected in the code word whose location is determined in S9 or S11 (S12). Then, the check digit is calculated based on the mask pattern information (mask number) and error correction level information set in S12, and the format information including the error correction level, mask number, and check digit is generated as shown in FIG. (S13). Note that data such as a mask number and an error correction level to be recorded as format information may be input in S1.

  If the code type data acquired in S1 is the type (frame QR) of the information code 100 having the free area 110, the process proceeds to Yes in S14, and the format information generated in S13 includes the above-described format information. Mask processing is performed to reflect the specific mask (frame QR mask) (see FIG. 6). On the other hand, if the code type data acquired in S1 is not the type (frame QR) of the information code 100 having the vacant area 110, the process proceeds to No in S14 and has a mask pattern different from the mask pattern set in S16. Set the mask (model 1 mask or model 2 mask). After masking the format information in S15 or S16, the format information after the mask processing is arranged at a predetermined position 105 in the code area (S17).

  After the specific pattern area, the data recording area, and the error correction area are thus configured, the constituent elements of the empty area 110 are arranged (S18). In the example of FIG. 3, since the position of the empty area 110 (that is, the position of the image area 121) is specified by the row position and the column position, respectively, in S18, the area specified by the position specified in this way Determine the components of Specifically, some or all of the images taken in S100 are arranged in the empty area 110. In this way, the information code 100 is generated. FIG. 13C shows an example of the information code 100 generated by incorporating the photograph of FIG. 13A and the keyword of FIG. 13B. If the code type data acquired in S1 is not the type (frame QR) of the information code 100 having the free area 110, the process of S18 may be omitted.

  After the information code 100 or other two-dimensional code is generated in this way, the generated information code is stored (S103). For example, when the information code 100 is generated, the information code 100 is stored in a predetermined storage area (a specific folder or the like). By storing the information code 100 as described above, the image and the keyword included in the information code 100 are stored in a form linked with the information code 100. In addition, when a general two-dimensional code is generated, it may be similarly stored in a predetermined storage area (such as a specific folder), or a specific storage area defined for a general two-dimensional code Even if you save it. Further, the storage process in S103 may be a process of storing in the generation apparatus 2 or a process of transmitting an information code to the management apparatus 90 and storing in the management apparatus 90. By performing such storage processing every time the information code 100 is generated, the information code 100 is sequentially stored in a predetermined storage area configured in the storage unit of the generation device 2 or the management device 90.

(Information code usage processing)
Next, information code usage processing will be described. The usage process illustrated in FIG. 12 is a process executed when a predetermined operation is performed in the generation device 2 or the usage device 40. For example, in a system in which the information code 100 is accumulated in the storage unit 5 of the generation device 2, the use process shown in FIG. 12 is performed by performing a predetermined operation on the generation device 2. Further, in a system in which the information code 100 is stored in the storage unit 95 of the management device 90, the usage process of FIG. 12 is performed by performing a predetermined operation on a terminal such as the generation device 2 or the usage device 40. . In the following, a case where an information code is stored in the storage unit 5 of the generation device 2 will be described as a representative example.

  The usage process of FIG. 11 is executed when a predetermined operation (for example, operation of the operation unit 4 or the like) is performed by the user, for example, and accepts specification of a keyword or a command after the process starts (S201). After the processing of S201, a plurality of information codes stored in the storage unit 5 are read in order, and the data content recorded in each data recording area of each information code is confirmed (S202).

The reading of each information code in S202 is performed in the flow as shown in FIG. 12, for example.
First, the format information is decoded (S40). In this process, an information code image (accumulated image) to be read is analyzed, and the shape of the information code is detected. For example, when the information code 100 shown in FIGS. 5 and 8 is a reading target, recognition of the position detection pattern 104 and detection of the outer shape of the two-dimensional code are attempted by a known method. Specifically, the position detection pattern 104 is detected by a known method for detecting a 1: 1: 3: 1: 1 waveform, which is performed with a QR code (registered trademark), and the information code 100 to be read is detected. What is necessary is just to detect an external shape by the well-known method performed by QR code (trademark). Note that the outer shape detection method may be another method as long as it can detect the shape of a specific pattern or the outer shape of a two-dimensional code. When the outer shape of the information code is detected and the code area of the information code can be extracted, the information (format information) at a predetermined position of the information code is decoded, and the type and mask correction level of the imaged information code are determined. get. For example, if the object to be read is the information code 100 shown in FIGS. 5 and 8, etc., the mask process is performed on the information recorded at the predetermined position 105 as described above based on the above-described specific mask (frame QR mask). Then try to decipher. When the check digit matches when the mask processing is canceled by the above-described method for canceling the mask of the specific mask (that is, calculated based on the correction level data and the mask number data when the predetermined position 105 is decoded) When the check digit matches the check digit recorded at the predetermined position 105), it is possible to specify the type of the information code 100 (the type having the free area 110), and an error included in the format information The correction level and mask number can also be acquired. When the mask process can be canceled based on the specific mask as described above (that is, when it is recognized that the information code 100 is the type (frame QR)), the process proceeds to Yes in S41. On the other hand, when the mask processing can be canceled by a mask other than the specific mask (frame QR mask) such as the model 1 mask and the model 2 mask shown in FIG. 6, the process proceeds to No in S41. When the mask process can be canceled by another mask, the two-dimensional code imaged in S40 is a case of a known QR code (registered trademark). Will be deciphered. In FIG. 9, the process in the case of No in S41 is omitted.

  When the process proceeds to Yes in S41, that is, when the reading target is the type of the information code 100 (frame QR), first, the data recorded in the data recording area is decoded (S42). Specifically, based on the mask number included in the format information acquired in S40, the mask of the entire code (specifically, the area of the code word) is released. Then, based on the header data (frame QR header) provided at the beginning of the data word, the original code size (the model number and format of the other type code 120) is specified, and the diagram is converted according to the same layout conversion table as in FIG. 5 Return from the information code 100 as shown in the right figure to the original code (another code 120) as shown in the left figure. Specifically, the code word (data code word and error correction code word) of each arrangement candidate position of the information code 100 is arranged in the other type code 120 associated with each arrangement candidate position in the arrangement conversion table. Reposition to the position. By performing the arrangement conversion in this way, another type code 120 in which the data code word and the error correction code word arranged in the information code 100 are recorded is obtained. Since the other type code 120 is a known QR code, the data is decoded by a method similar to the known QR code (that is, error correction calculation is performed by a known method based on the error correction code word). Decode the data code word).

  After decoding the data in the data recording area in S42, the format information included in the header data (frame QR header) is read. If the format information is format information indicating "image format", the process proceeds to Yes in S44. For other formats, the process proceeds to No in S44. In FIG. 9, the process in the case where the process proceeds to No in S44 is omitted.

  When the process proceeds to Yes in S44 (that is, when the format information included in the header data (frame QR header) is format information indicating “image format”), the image area position information (position data) included in the header data is read. (S45). Then, the position of the image area 121 in the information code 100 is specified (S46). Specifically, in this configuration, it is assumed that a rectangular image region is formed, and in S46, the code image is analyzed to specify the positions of the four corners of the image region in the code image. For example, when position information (for example, combinations of column positions and row positions at each position of the four corners) of the image area 121 is recorded as the image area position information (position data), the four corners of the image area are recorded based on the position data. Can be specified.

  After specifying the positions of the four corners of the image area 121 in S46, the image of the image area 121 is extracted. Note that the image extracted in S47 may be, for example, a bitmap format, or may be another known image file format such as a GIF format or a JPEG format. In the example of FIG. 12, an example in which the image of the image area 121 can be extracted and used when the information code 100 is read is shown. However, in the process of S202, the processes of S45 to S47 may be omitted. .

  After S202, it is determined whether or not there is a plurality of information codes stored in the storage unit 5 that include the keyword specified in S201 (S203). , Processing according to the command specified in S201 is performed. On the other hand, if none of the information codes 100 stored in the storage unit 5 includes the keyword specified in S201, the process proceeds to No in S203, and the process of FIG. 11 ends.

  For example, in the example of FIG. 13, the keyword “school trip” is input and recorded in the information code 100 when the information code 100 is generated. As described above, when a plurality of information codes 100 are stored in the storage unit 5 for the keyword “school trip”, if the keyword “school trip” is specified in S201, the information code 100 is extracted in the process of S202. can do. In S201, when the keyword “school trip” is specified and a command to move to a predetermined folder is input, these information codes 100 (“school trip”) stored in the storage unit 5 are input. The information code 100) including the keyword can be moved to a predetermined folder designated by the command and stored again.

  Note that the command specified in S201 is not limited to moving to a predetermined folder, and may be a command for instructing list display, for example. In this case, for example, when the keyword “school trip” is specified in S201 and a command for instructing a list display is input, these information codes 100 (“school trip”) stored in the storage unit 5 are entered. It is possible to display a list of information codes 100) including keywords on the display unit 6.

  In addition, the command specified in S201 may be a command for instructing transmission to a predetermined site on the Internet (for example, a site displaying contents stored in the management device 90). In this case, for example, when the keyword “school trip” is designated in S201 and a command for instructing transmission to the predetermined site is input, these information codes 100 (““ The information code 100 including the keyword “school excursion” can be transmitted to a predetermined site on the Internet (for example, a site displaying the contents stored in the management device 90). In this case, the transmitted series of information codes (information code 100 including the keyword “school excursion”) may be displayed as an album as shown in FIG.

(Example of effects of this configuration)
According to this configuration, an information code representing an image in the code area can be generated as a management target and stored in the storage unit in a usable state. Moreover, the information code generated and stored is the data recording area in which recording data related to the image in the image area is recorded, and the image in the information area is associated with the recording data. Thus, efficient management using the information in the data recording area becomes possible.

  For example, when it is desired to search for an information code having a desired image area, it is easy to extract a desired information code by performing a search based on the contents of the data recording area. Alternatively, when a specific type of information code is extracted from a plurality of information codes stored in the storage unit, or a plurality of information codes stored in the storage unit is classified, based on the contents of the data recording area By performing extraction and classification, more efficient work or processing becomes possible.

According to this configuration, since the information code can be generated by the portable terminal possessed by the user, the degree of freedom in the place where the information code is generated is increased. Further, since the information code generated by the mobile terminal can be stored in a storage system that can communicate with the mobile terminal, it is advantageous in applications where it is desirable to store the information code in a place different from the mobile terminal.

Also, in this configuration, the information code generation unit is configured to record address information that specifies the location of the storage unit that stores the information code in the data recording area of the information code.
If address information for specifying the storage location of the information code is recorded in the data recording area of the information code in this way, it is advantageous in applications where it is desired to access the storage section when reading the information code.

In this configuration, the image acquisition unit includes an imaging unit that captures a predetermined imaging range, and acquires part or all of the captured image generated by the imaging unit as an image to be incorporated into the information code. It has become.
According to this configuration, an information code including an image captured by the user using the imaging unit can be easily generated, and such an information code can be easily managed efficiently.

Further, in this configuration, the information code generation unit creates an empty area, which is an area in which the decoding target data is not recorded by the cell, at a position other than the specific pattern area and the data recording area within the code area. A size larger than the size is provided, and an empty area is set as an image area.
According to this configuration, it is possible to secure an area (empty area) in which the data to be decoded is not recorded by the cell at a position other than the data recording area and the specific pattern area in the code area, and this empty area is an image area. Can be generated as an information code. Since the empty area is an area in which the data to be decoded is not recorded by the cell, the image area is hardly affected by the cell, and the image area can be configured more freely.

In this configuration, the generation system is provided with an operation unit capable of inputting information by an external operation. The data acquisition unit is configured to acquire information input by an external operation on the operation unit as at least part of the recording data.
According to this configuration, the user can input information desired to be recorded in the data recording area by operating the operation unit.

Further, in this configuration, the reading system includes a receiving unit that receives a search condition, and the reading unit reads a plurality of information codes stored in the storage unit when the search condition is received by the receiving unit. The configuration is such that, from a plurality of information codes stored in the storage unit, a corresponding code whose reading result satisfies a search condition is extracted.
According to this configuration, in the configuration in which the information code is stored and managed in the storage unit, the code satisfying the search condition can be extracted by actually reading the information code in the storage unit and matches the desired search condition. It becomes possible to specify the information code more accurately and more easily.

Further, in this configuration, the reception unit is configured to receive a keyword as a search condition, and the reading unit reads a plurality of information codes stored in the storage unit when the keyword is received by the reception unit. The configuration is such that, from among a plurality of information codes stored in the storage unit, a code in which a keyword received by the receiving unit is recorded in the data recording area is extracted as a corresponding code.
According to this configuration, in the configuration in which the information code is stored and managed in the storage unit, it is possible to actually read the information code in the storage unit and extract the corresponding code in which the desired keyword is recorded. It is possible to more accurately and easily specify the information code that matches the above.

[Modification 1 of the first embodiment]
In the process of FIG. 11 performed by the generation apparatus 2 or the like, when keywords and commands are input in S201, the keywords and commands are transmitted to the management apparatus 90. In the management apparatus 90, the processes of S202, S203, and S204 are performed. Processing may be performed. In this case, for example, when the keyword “school trip” and the command “list display” are specified in S201 of FIG. 11, these pieces of information are transmitted to the management apparatus 90 and the information code in the storage unit 95 is transmitted. 100 may be read and the information code 100 to which the keyword “school trip” is attached may be displayed in a list on the display unit 5 of the generation device 2 as shown in FIG.

  In this example, the image generated in S100 of FIG. 9 may be a moving image or a continuous image of any of a plurality of continuous still images. In this case, in S102, the information code 100 may be generated with a configuration in which a partial image of the generated continuous image is represented in the image area 121. In this case, the generated information code 100 (information code representing a partial image of a continuous image in the image area) and the continuous image may be associated with each other and stored in the storage unit 95. In this configuration, the storage unit 95 corresponds to an example of an accumulation unit and a continuous image registration unit, and registers a continuous image when the information code 100 representing a partial image of the continuous image is represented in the image area. To work.

  In such a system, when the information code 100 (information code representing a partial image of a continuous image in the image area 121) is generated, the continuous image in the storage unit 95 (continuous image registration unit) is generated. It is desirable to record registration destination information for specifying the registration destination in the data recording area. In such a configuration, when a part of the information code 100 displayed as a list is associated with a continuous image as shown in FIG. 14, for example, the apparatus 2 specifies and reads the information code 100. As a result, it is possible to access the continuous image that is the source of the image included in the information code 100 and display the continuous image on the display unit 6 of the device 2. In the example of FIG. 14, in the list display, for the information code 100 including a part of the continuous image, the entire code including the data recording area is displayed, and only one still image is displayed instead of the continuous image. For the information code 100 including “”, only the image is displayed with the periphery of the image area omitted.

  In this example, for example, the control unit 3 of the generation device 2 functions as a registered image acquisition unit, reads registration destination information recorded in the data recording area, and is registered from the continuous image registration unit specified by the registration destination information. Works to get an image. The display unit 6 corresponds to an example of a continuous image display unit, and functions to display the continuous image when the registered image acquisition unit acquires the continuous image.

In this configuration, the image acquisition unit is provided with a continuous image acquisition unit that acquires a continuous image of at least one of a moving image or a plurality of continuous still images. Further, the information code generation unit is configured to generate an information code with a configuration in which a partial image of the continuous image acquired by the continuous image acquisition unit is represented in an image region. Can be stored.
According to this configuration, it is possible to generate and store a novel information code having a configuration in which a part of the continuous image is represented in the image area based on a moving image or a plurality of continuous still images.

Further, in this configuration, the generation system includes a continuous image registration unit that registers a continuous image when the storage unit stores an information code representing a partial image of the continuous image in the image area. In the case where an information code representing a partial image of a continuous image is generated in the image area, registration destination information for specifying a registration destination of the continuous image in the continuous image registration unit is recorded in the data recording area. Yes. The reading system includes a registered image acquisition unit that acquires a continuous image registered from the continuous image registration unit specified by the registration destination information when the reading unit reads the registration destination information recorded in the data recording area. A continuous image display unit that displays the continuous image when the registered image acquisition unit acquires the continuous image.
In this configuration, when an information code in which a part of a continuous image is represented in the image area is generated and stored, the continuous image can be registered, and the registration destination information of the continuous image can be registered as the information code. Can be included. When the information code is read by the reading system, a continuous image can be acquired from the continuous image registration unit specified by the registration destination information in the information code and displayed by the continuous image display unit. According to this method, continuous images can be managed in association with information codes. In addition, since the continuous image can be easily accessed by reading the information code, the convenience in using the continuous image is very high.

[Second Embodiment]
Next, a management system according to the second embodiment will be described with reference to FIGS.
This management system is, for example, a system that is handled at a site such as an accident or incident as shown in FIG. In this example as well, the information code 100 is generated and stored according to the flow shown in FIGS.

  In this example, the user operates the generating device 2 to take a picture at the site as shown in FIG. 15 (S100). FIG. 16 shows a state where a photograph is taken at the site of an accident or incident as shown in FIG. Thereafter, a keyword input by the user is accepted (S101). In S101, the user designates an image range from the captured images obtained in S100, and then inputs a keyword to be attached to the image range. For example, when the entire range of the captured image in S100 is designated, a keyword such as “the entire case site” is attached in S101, and the information code 100 incorporating the entire range of the captured image in FIG. 18 is added in S102. Can be generated. In addition, in the captured image obtained in S100, when an evidence part article such as a mobile phone, an ashtray, and a knife is individually specified, in S101, each image includes “January 1, 2000, 10:30, evidence. Product 1, mobile phone ”“ January 1, 2000 10:30, Evidence 2, Ashtray ”“ January 1, 2000 10:30, Evidence 3, Cutlery ”, etc. 19A, FIG. 19B, and FIG. 19C can generate the information code 100 incorporating the individual ranges. In this case as well, the storage process is performed so that the one or more information codes 102 generated in S102 are stored in a predetermined location (for example, a predetermined area of the storage unit 5) (S103).

  The information code 100 stored in this way can be used for the case record as shown in FIG. When the case record as shown in FIG. 20 (A) is created with electronic data or paper media, as shown in FIG. 20 (B), the information code (FIGS. 18, 19A, 19 (B) and 19 (C)) may be incorporated so as to be displayed. Further, when generating the information code 100 as shown in FIGS. 18 and 19, if there is an item to be commented on each image, the comment is input in the processing in S 101 and the comment is incorporated. The information code 100 may be generated. In this way, as shown in FIG. 20B, when the information code 100 shown in the case record is read, it is possible to grasp the comments attached to the image of the information code 100.

(Example of effects of this configuration)
This configuration also has the same effect as the other configurations.
Furthermore, in this configuration, in the generation system, a selection operation unit capable of selecting an image range to be included in the information code from the captured images captured by the imaging unit, and a designation operation by the selection operation unit And an image extracting unit that extracts an image in the image range from the captured image captured by the imaging unit. The information code generation unit is configured to generate an information code with a configuration that represents an image in the image range extracted by the image extraction unit in an image region.
According to this configuration, it is possible to arbitrarily specify a range desired to be incorporated into the code from the captured image captured by the imaging unit, and it is easy to generate an information code that more reflects the user's desire.

In this configuration, the data acquisition unit acquires at least one of the date and time when the information code is generated by the information code generation unit as at least a part of the recording data.
In this configuration, since the date or time when the information code is generated is recorded in the data recording area, it is particularly advantageous in applications where it is desired to manage the information code using the date or time. For example, it is possible to select information codes of a specific time and group them, or to extract information codes of a specific time by a simple search.

In this configuration, the data acquisition unit acquires the name of the target represented in the image area of the information code as at least a part of the recording data.
In this configuration, since the name of the object represented in the image area is recorded in the data recording area, it is particularly advantageous in applications where it is desired to manage the information code using the name. For example, it is possible to select and group information codes with specific names, or to extract information codes whose specific names are represented in the image area by a simple search.

  In this configuration, the data acquisition unit acquires at least one of a comment and a message as at least a part of the recording data. In this configuration, since comments and messages are recorded in the data recording area, it is particularly advantageous in applications where it is desired to manage information codes using comments and messages.

[Third embodiment]
Next, a management system according to the third embodiment will be described with reference to FIGS.
This management system is, for example, a system handled in a scene as shown in the upper part of FIG. Also in this example, the information code 100 is generated in the flow as shown in FIG.

  In this example, in the process of FIG. 9, the user operates the generating device 2 to take a picture at the site as shown in the upper part of FIG. 21 (S100). Thereafter, a keyword input by the user is accepted (S101). Even in S101, as shown in the lower part of FIG. 21, the user designates an image range from the photographed image obtained in S100 by a drag operation or the like, and then inputs a keyword to be attached to the image range. For example, as shown in the lower part of FIG. 21, when one or more specific persons are individually designated in the captured image obtained in S100, keywords such as “Taro” and “Hanako” are attached in S101. In S102, an information code 100 incorporating an individual range as shown in FIG. 22 can be generated. In this case as well, the storage process is performed so that the one or more information codes 102 generated in S102 are stored in a predetermined location (for example, a predetermined area of the storage unit 5) (S103). Alternatively, the generated information code 100 may be printed or transmitted as data instead of the storage process of S103 or together with the storage process of S103. Further, in the data recording area of the information code 100, a URL of a blog or a message to a friend may be recorded. Then, when the information code 100 is read, a present image as shown in FIG. 23 may be displayed by a blog specified by the URL, an application of the read person's terminal, or the like.

(Example of effects of this configuration)
This configuration also has the same effect as the other configurations.
Also in this configuration, in the generation system, a selection operation unit capable of selecting an image range to be included in the information code from the captured images captured by the imaging unit and a selection operation performed by the selection operation unit are designated. An image extraction unit that extracts an image in the image range from the captured image captured by the imaging unit is provided. The information code generation unit is configured to generate an information code with a configuration that represents an image in the image range extracted by the image extraction unit in an image region.
According to this configuration, it is possible to arbitrarily specify a range desired to be incorporated into the code from the captured image captured by the imaging unit, and it is easy to generate an information code that more reflects the user's desire.

Further, in this configuration, the data acquisition unit acquires the name of the object (for example, the name of the person to be displayed) displayed in the image area of the information code as at least a part of the recorded data. .
Even in this configuration, the name of the object represented in the image area is recorded in the data recording area, which is particularly advantageous in applications where it is desired to manage the information code using the name. For example, it is possible to select and group information codes with specific names, or to extract information codes whose specific names are represented in the image area by a simple search.

  In this configuration, the data acquisition unit acquires the message as at least part of the recording data. In this configuration, since comments and messages are recorded in the data recording area, it is particularly advantageous in applications where it is desired to manage information codes using comments and messages.

[Fourth embodiment]
Next, a fourth embodiment will be described with reference to the drawings.
The management system of the fourth embodiment is the same as that of the first embodiment in terms of hardware configuration, and the configuration as shown in FIGS. 1 and 2 is used.

  In the management system of the fourth embodiment, the information code 200 as shown in FIG. 24B is generated by the information code generator 2 (see FIG. 1 and the like). Even in this configuration, a specific pattern area in which a specific pattern (position detection pattern 204) having a predetermined shape is arranged inside the code area, a data recording area in which data is recorded by a plurality of types of cells, and information code reading An image area 121 that is subject to predetermined search processing by the apparatus 10 is provided.

  In this configuration, a configuration other than the configuration in the empty area 210 is configured as a known QR code (registered trademark). First, as shown in FIG. A recording area and an error correction code recording area for recording an error correction code by a plurality of types of cells are provided. The recording method of the data code word in the data recording area and the recording method of the error correction code word in the error correction code recording area are the same as those of the known QR code (registered trademark), for example, a method defined in JISX0510 The arrangement of the position detection pattern 204 in the code area, the arrangement of the data code word in the data recording area, and the arrangement of the error correction code word in the error correction code recording area are determined.

  However, as shown in FIG. 24A, an information code 200 ′ in which a code word of a partial region is configured as a code word expressed only by white cells is generated, and thus the region expressed only by white cells With AR as a free area 210, an image area 121 is provided in this free area 210 as shown in FIG. In the example of FIG. 24B, an image T1 similar to that of the first embodiment is represented in the empty area 210. When configured in this way, the configuration is different from the original data display as shown in FIG. 24A, but the error in the data in the empty area 210 is corrected by the error correction recorded in the error correction code recording area. A known error correction may be performed using a code.

  In addition, in the information code 200 shown in FIG. 24B, the position of the empty area 210 is specified in advance. Therefore, when the design and information are added and displayed in the empty area 210, the error position by this display is set in advance. I know that. Therefore, the error correction code in the error correction code recording area can be configured to perform erasure correction using the position of the empty area 210 as the error position. In this case, information indicating the position of the vacant area 210 is recorded in the data recording area in advance, or stored in the reading apparatus 10 (FIG. 1) in advance, so that the reading apparatus 10 can read the vacant area at the time of reading. The position of 210 (that is, the position of the data code word in which an error has occurred) can be specified, and the reader 10 can determine the position of the data code word existing in the empty area 210 whose position is specified in this way. In order to correct the error, the erasure correction may be performed using the error correction code recorded in the error correction code recording area.

  Further, when a part of the existing QR code (registered trademark) is configured as the empty area 210 as shown in FIG. 24, the identification information as shown in FIG. 26A is included in the data recorded in the data recording area. Just keep it. FIG. 26 (A) conceptually shows the structure of the data to be decoded recorded in the data recording area. In this example, data of a predetermined structure (%% IMAGE %%) is present at the beginning of the data to be decoded. It is attached. With this configuration, when the reader 10 detects the identification information (%% IMAGE %%) from the data to be decoded recorded in the data recording area, the code in which the image area 121 exists is detected. Conversely, when the identification information (%% IMAGE %%) cannot be detected, it is handled as a normal code and a normal decoding process is performed. In this example, it is desirable that the data in the data recording area includes position data for specifying the position of the image area and other accompanying information in addition to the normal data. The data shown in FIG. 26 (A) indicates the data to be decoded that is arranged before the end terminal in the data recorded in the data recording area, and the padding that is arranged after the end terminal. The code is omitted. In this configuration, for example, the entire area of the padding code can be displayed with only white cells, and this area can be handled as the empty area 210.

  Moreover, the example of identification information is not restricted to this example, For example, you may make it use a mode number for exclusive use as a mode number. For example, in the QR code standard, 1: numerical mode, 2: alphanumeric mode, 3: concatenation mode, etc. are defined, and 14: image recognition mode may be provided as one of such mode numbers. Good. In such an example, when the mode number “14” is set, the image area 121 may be treated as existing.

[Fifth Embodiment]
Next, a fifth embodiment will be described.
The management system of the fifth embodiment is also the same as that of the first embodiment in terms of hardware configuration, and the configuration shown in FIGS. 1 and 2 described above is used.

  In the management system of the fifth embodiment, the information code 300 as shown in FIG. 25B is generated by the information code generation device 2 (see FIG. 1 and the like). Even in this configuration, a specific pattern having a predetermined shape (L-shaped alignment pattern 304a and light cells and dark cells are alternately arranged one by one inside the code region, and L along the boundary of the code region. A specific pattern area in which a timing pattern (timing cell) 304b) constituting a character-shaped area is arranged, and a data recording area in which data is recorded by a plurality of types of cells are provided. The empty area 310 in which at least one of data recording and design display can be performed at a position different from the method of recording data in the data recording area is set to a predetermined size larger than the size of a single cell. Is provided.

  In this configuration, except for the configuration of the empty area 310, it is configured as a known data matrix code. First, as shown in FIG. 25A, in the code area, a specific pattern area, a data recording area, An error correction code recording area for recording an error correction code by a plurality of types of cells is provided. The recording method of the data code word in the data recording area and the recording method of the error correction code word in the error correction code recording area are the same as the known data matrix code, and the alignment pattern 304a and timing pattern 304b in the code area. The arrangement of the data code word in the data recording area and the arrangement of the error correction code word in the error correction code recording area are determined in accordance with, for example, the ECC200 version.

  However, as shown in FIG. 25A, an information code 300 ′ in which a code word of a partial region is configured as a code word expressed only by white cells is generated, and thus the region expressed only by white cells. AR is a free area 310, and the free area 310 is an image area 121 as shown in FIG. When the free area 310 is used as the image area 121 as shown in FIG. 25B, the data display in the free area 310 is different from the original data display as shown in FIG. A known error correction may be performed using the error correction code recorded in the error correction code recording area.

  In addition, in the information code 300 shown in FIG. 25B, the position of the empty area 310 is specified in advance. Therefore, when a design or information is added and displayed in the empty area 310, the error position by this display is set in advance. I know that. Therefore, the error correction code in the error correction code recording area can be configured to perform erasure correction using the position of the empty area 310 as the error position. In this case, information indicating the position of the empty area 310 is recorded in the data recording area in advance, or is stored in the reading apparatus 10 (FIG. 1) in advance, so that the reading apparatus 10 can read the empty area at the time of reading. The position of 310 (that is, the position of the data code word in which an error has occurred) can be specified, and the reader 10 can determine the position of the data code word existing in the empty area 310 in which the position is specified in this way. In order to correct the error, the erasure correction may be performed using the error correction code recorded in the error correction code recording area.

  Further, when a part of the existing data matrix code is configured as the empty area 310 as shown in FIG. 25, the identification information as shown in FIG. 26B should be included in the data recorded in the data recording area. Good. FIG. 26B conceptually shows the structure of the data to be decrypted recorded in the data recording area. In this example, data of a predetermined structure (%% IMAGE %%) is present at the beginning of the data to be decrypted. It is attached. With this configuration, when the reader 10 detects the identification information (%% IMAGE %%) from the data to be decoded recorded in the data recording area, the code in which the image area 121 exists is detected. Conversely, when the identification information (%% IMAGE %%) cannot be detected, it is handled as a normal code and a normal decoding process is performed. In this example, it is desirable that the data in the data recording area includes position data for specifying the position of the image area and other accompanying information in addition to the normal data.

  Moreover, the example of identification information is not restricted to this example, For example, you may make it use a codeword for exclusive use. As the specification of the data matrix code, for example, when 0 to 128 is defined as an ASCII character and 233 is a connection mode, “234” may be newly defined as a special code word for image recognition. In such an example, when the code word “234” is included in the data in the data recording area, it may be handled as a code in which the image area 121 exists. In addition, when an unused code word exists, an unused code word is included as identification information, and when an unused code word is included in data in the data recording area, an image area 121 exists. It can be handled as a code.

The present invention is not limited to the embodiments described with reference to the above description and drawings. For example, the following embodiments are also included in the technical scope of the present invention.

  In the first embodiment and the like, the position data indicating the position of the image area (for example, the image area position information shown in FIG. 3) is included in the information code 100. However, the information code 100 is limited to such an example. Absent. For example, the information code generation device 2 may be configured to generate the information code so that the image area is arranged at a predetermined position in the empty area. In this case, information for specifying a predetermined position (information such as image region position information shown in FIG. 3) may be stored in the storage unit 5. Further, in this case, the information code reader 10 stores the specific information (information such as the image area position information shown in FIG. 3) for specifying the predetermined position in the memory 35 as in the information code generator 2. Good. Then, in the information code reader 10, in S45 of FIG. 9, such specific information is read from the memory 35 to specify the information input area, and the subsequent processing may be performed. In this case, the image area position information shown in FIG. 3 may not be included in the header data.

  The present invention can also be configured as a display device capable of displaying any one, plural, or all of the information codes described above. Moreover, it can also be configured as a printing apparatus capable of printing any one, plural or all of the information codes described above. Furthermore, it can also be configured as a computer-readable program for generating any one, plural or all of the information codes described above. Moreover, it can also be comprised as a recording medium which recorded the program for producing | generating the 1 or several or all the information code mentioned above. Furthermore, it can also be grasped as an information code medium (a printed material, a formed material formed by direct marking, etc.) to which one or a plurality of or all information codes are attached. Moreover, it can also be grasped as a display image on which one, a plurality, or all of the information codes described above are displayed.

  1 and the like show an example in which the information code generation device 2 and the information code reading device 10 are configured as separate devices, but the information code generation device 2 may be configured as the information code reading device 10. Good. In addition, the information code generation device 2 may be configured by a plurality of devices, and the information code reading device 10 may be configured by a plurality of devices.

  In the above embodiment, an example in which the empty area 110 is provided in the center of the code area has been described. However, the arrangement of the empty area 110 is not limited to this example. Similarly, the position of the image area 121 is not limited to the above example. For example, an empty area may be provided near the periphery of the code area, and the image area 121 may be provided at this position. In addition, as the design of the image area, various other designs can be adopted as long as the configuration includes a figure, a pattern, a color, or a combination thereof. In addition, when information is displayed instead of the design or together with the design, the contents of the information are various.

  In the above embodiment, a QR code is taken as an example of the other type code, and a specific pattern of the QR code is given as an example of the specific pattern used in the information code 100. However, other types of two-dimensional codes may be used. For example, a data matrix code may be used as the other type code, and a specific pattern used in the information code 100 may be used as the specific pattern of the data matrix code.

  The correspondence in the arrangement conversion table set as shown in FIG. 5 can be arbitrarily changed as shown in FIG. For example, when the arrangement conversion table set as shown in FIG. 5 in the information code generating device 2 and the information code reading device 10 is changed as shown in FIG. 7, the generated information code 100 includes the 22nd to 23rd codes. The arrangement of words from the arrangement shown in the right figure of FIG. 5 (the arrangement recorded in the 22nd to 23rd candidate positions) to the arrangement shown in the right figure of FIG. 7 (the arrangement recorded in the 42nd to 43rd candidate positions) As a result, the position and shape of the empty area 110 also change. In this case, the arrangement candidate positions Nos. 22 to 23 may be empty areas, or arrangement positions of other code words. That is, in this configuration, the position and shape of the empty area 110 can be adjusted by adjusting the arrangement conversion table, and the degree of freedom in configuring the empty area can be further increased.

  In the above-described embodiment, an example in which the empty area 110 is provided and the image area is provided in the empty area 110 has been described. For example, an image as described above is provided by overwriting or the like in a cell arrangement area of a general two-dimensional code (for example, QR code) capable of error correction, and error correction is performed on data in the area crushed by such an image area. You may make it restore by.

  In the above embodiment, an example of the “code area” is shown. However, the “code area” may be a minimum square area or rectangular area that includes all of the plurality of types of cells constituting the information code, and the inner edge of the code area. The cell may not be arranged in a part of the part. For example, as shown in the information code 800 of FIG. 27, the empty area 810 may be formed adjacent to the periphery of the code area. In this case, the minimum square area or rectangular area including all of the plurality of types of cells constituting the information code 800 is as indicated by a one-dot chain line AR, and the outer edge of the empty area 810 is as indicated by a two-dot chain line AR2, for example. Further, it is sufficient that at least a part of the image area exists in the code area, and a configuration in which the remaining part exists outside the code area as in the image area AR3 of FIG. In the example as shown in FIG. 28, information for specifying the range of the image area AR3 may be recorded in advance in the data recording area.

  In the above embodiment, a bright cell such as a white cell and a dark cell such as a black cell are exemplified as a plurality of types of cells constituting the code area. However, a specific pattern area, a data recording area, and an error correction code in the code area are exemplified. The recording area may be configured as a first type cell having a predetermined density, luminance, and color, and a second type cell that is different in density, luminance, or color from the first type cell. Alternatively, the specific pattern area, the data recording area, and the error correction code recording area in the code area may be configured by three or more types of cells each having different density, luminance, or color.

  In the above embodiment, an example in which a plurality of cells having a square outer shape are arranged in the specific pattern area, the data recording area, and the error correction code recording area in the code area has been described. However, the outer shape of each cell is a square other than a square. It may be a polygon other than a rectangle, or a figure such as a circle or an ellipse.

  In the above embodiment, the position detection pattern 104, the timing pattern 106, the alignment pattern 108, and the like are illustrated as examples of the specific pattern. However, the area is configured as a fixed pattern regardless of the contents of the data recording area and the error correction code recording area. If so, the figure constituting the specific pattern may be another unique figure.

  In the above embodiment, an example of an empty area is shown. However, an empty area is an area where data to be decoded is not recorded by a cell, and information display or image display is performed by a method different from the method of recording data in the data recording area. Any area may be used as long as it is a display area. For example, as in the first embodiment, a vacant area may be configured as an area where no code word is arranged. In a known QR code, an error correction code word that represents an error correction code or data to be decoded is used. An area where a data code word to be expressed is not arranged and a padding code word is arranged may be a free area. Further, in any free area, “information display by a method different from the method of recording data in the data recording area by cell” can be performed, and this information display is exemplified in the above embodiment. In addition to information, other information such as letters, numbers, and other symbols may be used, or a method of displaying information that represents a specific product or service by a trademark or the like may be used. Further, in the free area, “image display by a method different from the method of recording data in the data recording area by cell” can be performed, and the display of this image is not limited to the image exemplified in the above embodiment, Various shapes, patterns, colors, combinations thereof, and the like can be represented.

Also, the information code 900 in FIG. 29 may be configured. In this example, the same empty area as that of the first embodiment is provided, but only the specification of the empty area is different from that of the first embodiment. In the example of FIG. 29, specific contents of areas other than some of the specific patterns are omitted, and in fact, bright cells and dark cells are arranged in an external area outside the empty area 910. Become. In the free space 910, for example, an image similar to the free space 110 of the first embodiment or an image similar to the free space of other embodiments is displayed.
Also in this configuration, a plurality of model numbers are prepared for the type of the information code 900. For each model number, the number of rows and columns of cells, the shape and position of a specific pattern, the position of format information, and the candidate position (address) of a code word Is predetermined. When the generating device 2 generates the information code 900, the model number information is arranged at a predetermined position in the code area (the reserved area 107 in the example of FIG. 29). Therefore, when the reading device 10 reads the information code 900, the code image of the information code 900 is analyzed, and the model number information arranged at a predetermined position is read, so that the number of rows and columns of cells of the information code 900, The shape and position of the specific pattern, the position of the format information, and the candidate position (address) of the code word can be grasped.
When generating the information code 900, one of the model numbers is selected from a plurality of model numbers prepared in advance. Thereby, the basic configuration (the position of the specific pattern 104, the number of rows and columns of cells, the candidate position of the code word) in the code area is determined. For example, the model number of the configuration shown in FIG. 29 has a cell array of 29 rows and 29 columns, and a specific pattern 104 having the same structure as a QR code (registered trademark) cut-out symbol at three predetermined corners. Is arranged. An area (predetermined position 105) for recording format information is provided at a predetermined position near the specific pattern 104. In addition, in the 29 × 29 matrix area, codeword candidate positions are determined in advance at positions other than the specific pattern 104 and the predetermined position 105, and addresses from 0 to 67 are assigned to the candidate positions. . In this way, since the configuration in the code area is defined in advance in the configuration corresponding to the model number, if the model number is specified, it is possible to specify which order code word is arranged at which position. Become. The information of the determined model number is recorded at a predetermined fixed position in the model number array. For example, in the example of FIG. 29, model number information is recorded in an area 107 specified by a predetermined type of hatching.
After the model number is determined and the basic configuration in the code area is determined, the shape and position of the empty area are determined. The method for determining the shape of the vacant area may be determined by, for example, a method of selecting from a plurality of candidate shapes prepared in advance, or shape designation information input from the outside to the information code generation device 2 You may decide by the method of setting to the shape according to. Or you may determine only to the fixed shape decided. Further, the position of the empty area may be determined as a predetermined fixed position, or may be determined by inputting information for designating the position by the user.
After the vacant area is determined, the information code 900 is configured such that the code word in the data recording area and the code word in the error correction code recording area are respectively arranged at the candidate position of the code word that deviates from the determined position of the vacant area. Is generated. For example, in the model number configured as shown in FIG. 29, specific patterns 104 are arranged at three corners, and 68 codeword candidates numbered from 0 to 67 with reference to the positions of the specific patterns 104 are used. The position is defined in advance. In such a layout, when the empty area 910 is determined as shown in FIG. 29, codeword candidate positions that at least partially enter the empty area 910 are excluded from the arrangement target positions, and the positions of the excluded codewords The code words are arranged in order as if skipping. For example, in the example of FIG. 29, since the empty area 910 is set so as to enter the candidate positions of the code words 50, 51, 53, 54, and 60 to 67, these 50, 51, 53, Code words are not arranged at the candidate positions of the 54th and 60th to 67th codewords. That is, after the code words are arranged in order at positions 0 to 49, the code words 50 and 51 are skipped and the code words are arranged at the position 52, and then the codes 53 and 54 are skipped and the codes 55 to 59 are skipped. The code words are arranged in order at the positions. In this way, the data code word obtained by encoding the data to be decoded and the error correction code word representing the error correction code can be reliably arranged at the candidate positions outside the empty area 910.
After determining the specific pattern area (specific pattern 104 or other specific pattern area), the format area (predetermined position 105), the model number area 107, each codeword area, and the like, the specific contents of the empty area 910 are determined. To decide. In this information code 900 as well, an information code 900 having the same function as in FIG. 1 can be configured by representing an image similar to the empty area 110 in the empty area 910. Note that the method of using the information code 900 is the same as in the first embodiment and other embodiments.
