  A WEB expansion display system 10 embodying the present invention includes an electronic paper device 12, a WEB server 13, a portable terminal 14, and the like. This WEB development display system 10 electronically displays an image (hereinafter referred to as a parallel image) in which each WEB page (hereinafter referred to as a parallel WEB page) presented in parallel with a WEB page being displayed on the mobile terminal 14 is arranged. By displaying it on the paper device 12, the information on those WEB pages can be viewed collectively.

  In this example, a parallel image in which the images of the WEB page being displayed on the portable terminal 14 are arranged together with the parallel WEB page is generated. However, the image of the WEB page being displayed may not be included in the parallel image.

  The WEB server 13 and the portable terminal 14 can be connected to the network 15, and can communicate with each other via the network 15. The network 15 may be anything as long as it connects the mobile terminal 14 and the WEB server 13, and the Internet, a dedicated line, a mobile phone line, a public wireless LAN, etc., or a mixture of them. But you can. In addition, the electronic paper device 12 and the portable terminal 14 can exchange data with each other by communication conforming to, for example, the NFC (Near Field Communication) standard.

  The WEB server 13 stores WEB data for displaying a WEB page, and provides the WEB data via the network 15. The WEB data is composed of content such as a well-known HTML file or an image embedded in a sentence described by the HTML file. Instead of the HTML file, a file described in another markup language may be used. Furthermore, an image or the like may be provided by another server. Although one WEB server 13 is illustrated in FIG. 1, a plurality of WEB servers may be provided.

  As is well known, the electronic paper device 12 displays an image input from the outside on the display screen 12a, and maintains the display image without supplying power after the image is displayed. As the electronic paper device 12, a display screen 12a whose display screen 12a is larger than a display screen (hereinafter referred to as a terminal screen) 14a of the portable terminal 14, for example, an A4 size is used.

  Although the electronic paper device 12 is used as a display medium, the display medium is not limited to this. For example, a display screen of a tablet terminal or a notebook or desktop PC larger than the portable terminal 14 can be used as the display medium. In this case, the parallel image is transmitted from the mobile terminal 14 to the tablet terminal or the like and displayed on the display screen. Further, a recording paper or the like can be used as a display medium. In this case, the parallel image is transmitted from the portable terminal 14 to a printer or a multifunction device having a print function, and the parallel image is recorded on the recording paper.

  The orientation of the image on the display screen 12a and the terminal screen 4a can be changed arbitrarily or automatically according to the posture of the electronic paper device 12 and the portable terminal 14. In the following, in order to simplify the description, the terminal screen 14a of the mobile terminal 14 is displayed in a vertically long posture, and the display screen 12a of the electronic paper device 12 is displayed in a horizontally long posture. It is assumed that the image is displayed so that it can be correctly viewed.

  As shown in FIG. 2, the electronic paper device 12 has a communication unit 21, a writing unit 22, and a display screen 12a. The communication unit 21 includes an antenna, a controller chip, and the like. Power is supplied from a reader / writer (in this example, the mobile terminal 14 side) by electromagnetic induction of a carrier wave during data communication, and the communication unit 21 uses that power. Each part of the electronic paper device 12 including the above operates.

  The electronic paper device 12 receives a parallel display image to be displayed from the portable terminal 14 through the communication unit 21. The communication unit 21 includes a memory 21 a that stores the size of the display screen 12 a and sends the memory 21 a to the mobile terminal 14. The size of the display screen 12 a is referred to when the mobile terminal 14 generates a parallel image to be displayed on the electronic paper device 12. The writing unit 22 generates a signal corresponding to the display method of the display screen 12ab and displays the received image on the display screen 12a.

  As the mobile terminal 14, a small-sized smartphone, for example, equipped with a terminal screen 14a of around 4 inches is used. The terminal screen 14a is a touch panel display provided with a touch panel, and various operations can be performed on the mobile terminal 14 by operating the terminal screen 14a. The mobile terminal 14 may be a personal information terminal (PDA), for example.

  As illustrated in FIG. 3, the mobile terminal 14 includes a control unit 30, a first communication unit 31, a second communication unit 32, an operation unit 33, a display unit 34, a specifying unit 35, an image generation unit 36, and the like. In response to the operation of the operation unit 33, the control unit 30 comprehensively controls each unit of the mobile terminal 14 and executes processing corresponding to the input operation.

  The first communication unit 31 communicates with the WEB server 13 via the network 15. The first communication unit 31 transmits a URL for designating a WEB page, a URL of an image embedded in the WEB page, and the like to the WEB server 13 and receives WEB data transmitted from the WEB server 13 in response thereto. The first communication unit 31 is an acquisition unit that acquires WEB data from the WEB server 13.

  The second communication unit 32 functions as a reader / writer for the communication unit 21 of the electronic paper device 12, supplies power to the communication unit 21, transmits parallel display image data, and displays the size of the display screen 12 a. And so on. The second communication unit 32 is an output unit that outputs to display on the display medium.

  The operation unit 33 includes a power button and a touch panel provided on the terminal screen 14a as described above. By operating the operation unit 33, it is possible to specify a WEB page to be referred to, select a link destination, and instruct parallel display of processing for displaying a parallel image on the electronic paper device 12.

  The WEB data acquired by the first communication unit 31 is input to the specifying unit 35 and the image generation unit 36 via the control unit 30. When the parallel display instruction is given, the specifying unit 35 analyzes the source code of the WEB page currently displayed on the terminal screen 14a, and is displayed as a link destination on the displayed WEB page. Among them, the parallel WEB page is specified. The specifying unit 35 acquires the URL of the specified parallel WEB page from the source code. By sending the URL of the parallel WEB page to the WEB server 13 via the control unit 30 and the first communication unit 31, the WEB data of the parallel WEB page is acquired.

  The method of specifying as a parallel WEB page by the specifying unit 35 can be specified using various conditions corresponding to the description of the source code. The following specific condition is an example.

Specific condition: A page that satisfies the following conditions 1 and 2 is defined as a parallel WEB page.
Condition 1: The parallel WEB page is presented as a link on the displayed WEB page, and the list display block (<UL> ~ </ UL> or <OL> ~ </ OL>) in the source code A list item (<LI> to </ LI>) described in the URL is designated by a URL as a link destination, and the URL designates an object to be displayed as a WEB page such as an HTML file or an image file.
Condition 2: The storage location of the object displayed as the WEB page is the same as the storage location of the HTML file of the WEB page being displayed.

The specific condition for the parallel WEB page is not limited to the above. For example, when the display format of the WEB page is specified using a style sheet, the parallel WEB page may be specified in consideration of the contents of the style sheet. Further, by using Condition 1 and Condition 3 below, the WEB pages presented in parallel with each other may be specified on the displayed WEB page.
Condition 3: Other list items in the same list display block satisfying the above condition 1 and other WEB pages (other than the WEB page being displayed) are specified as a link destination by a URL.

  The image generation unit 36 images the WEB page, and includes a rendering unit 37 and a parallelization processing unit 38. The rendering unit 37 performs rendering using the WEB data and generates an image for each WEB page. In rendering, the source code described in the HTML file is interpreted to lay out text in the HTML file, embedded images, etc., and color characters, backgrounds, and the like. This rendering may be the same as the rendering performed when the web browser displays the web page.

  Normally, a WEB page to be displayed on the terminal screen 14 a is imaged and sent to the display unit 34. When the parallel display instruction is given, each linked WEB page specified by the specifying unit 35 is imaged, and these images and the image of the WEB page being displayed on the terminal screen 14 a are sent to the parallel processing unit 38. The rendering when the parallel display instruction is given is performed in the same manner as in the normal case, whereby the layout of the images of the WEB pages in the parallel image is the same as that displayed on the terminal screen 14a.

  The parallel processing unit 38 converts a plurality of WEB page images into one parallel image for display on the electronic paper device 12. The parallel image in this example is a WEB page displayed on the mobile terminal 14 and each image of each parallel WEB page arranged in the horizontal direction to form one image. Each image in the parallel image has the same scale as that on the terminal screen 14a, and the display range (length) is sized according to the display screen 12a. That is, the width (the length in the horizontal direction) of each image in the parallel image is the same as the width of the WEB page on the terminal screen 14a. On the other hand, the length (length in the vertical direction) of each image in the parallel image is matched to the length in the vertical direction of the display screen 12a. Therefore, if the length of the display screen 12a is larger than the length of the terminal screen 14a, each image is wider than the range that can be viewed on the terminal screen 14a without scrolling.

  The display unit 34 includes a terminal screen 14a and a driver that drives the terminal screen 14a. When an image from the rendering unit 37 is input, the display unit 34 displays the image on the terminal screen 14a.

  Next, the operation of the above configuration will be described. The operator operates the operation unit 33 to display a desired WEB page on the terminal screen 14a by inputting, for example, a URL or selecting a link on the WEB page being displayed on the terminal screen 14a. . In the following description, it is assumed that the WEB page 41 shown in FIG. 4 is displayed on the terminal screen 14a of the mobile terminal 14 as an example.

  The WEB page 41 introduces the camera “AA” of the “digital camera XX series”, and “AA” is displayed on the tab 41a. In addition, tabs 41a for the cameras “BB”, “CC”, and “DD” are displayed side by side on the tab 41a for “AA”. In the characters of these tabs 41a, links to WEB pages that introduce the corresponding cameras are set. Accordingly, by selecting (touching) any of the characters “BB”, “CC”, and “DD” on the tab 41a, a WEB page that introduces the camera “BB”, “CC”, or “DD” is displayed. Is done. Accordingly, in the WEB page 41 introducing the camera “AA” being displayed, the WEB pages introducing the cameras “BB”, “CC”, and “DD” are presented in parallel with the WEB page 41 being displayed. Yes. Each WEB page that introduces the cameras “BB”, “CC”, and “DD” is a WEB page that is presented in parallel with each other.

  It should be noted that the same tabs are displayed when the WEB pages introducing the cameras “BB”, “CC”, and “DD” are displayed. Then, by selecting a character in a tab other than the currently displayed WEB page, the previous WEB page set for the selected character is displayed.

  The source code described in the HTML file of the WEB page 41 is as shown in FIG. 5, for example, and each tab 41a of “AA” to “DD” is surrounded by <UL> to </ UL>. The list display block is based on the description.

  As described above, when the parallel WEB page is presented on the displayed WEB page 41 and the operator wants to display these WEB pages in parallel on the electronic paper device 12, the parallel display instruction is given by operating the operation unit 33. I do. In response to this parallel display instruction, the control unit 30 controls the display unit 34 to display a guidance such as “Please bring the mobile terminal close to electronic paper” on the terminal screen 14a. Following this guidance, the operator brings the mobile terminal 14 close to the electronic paper device 12. Note that it may be detected that the portable terminal 14 has approached the electronic paper device 12 and this becomes a parallel display instruction.

  After the parallel display instruction, a carrier wave is output from the second communication unit 32, and when both are brought close to each other, power is supplied to the communication unit 21 of the electronic paper device 12 by the carrier wave. As a result, the electronic paper device 12 operates. Thereafter, the size of the display screen 12 a read from the memory 21 a is sent from the communication unit 21 to the second communication unit 32. Thereby, the control part 30 acquires the size of the display screen 12a. Based on the acquired size of the display screen 12a and the size of the terminal screen 14a, the control unit 30 calculates the number of displayable pages (four pages in this example) that can be displayed side by side on the display screen 12a. . Note that the portable terminal 14 may be separated from the electronic paper device 12 after obtaining the size of the display screen 12a. Note that the size of the display screen 12a of the electronic paper device 12 may be set in the mobile terminal 14 in advance.

  After calculating the number of displayable pages, the image generation unit 36 is operated, and the rendering unit 37 performs rendering again based on the HTML file of the WEB page 41 being displayed, and the image of the WEB page 41 obtained thereby is displayed. It is sent to the parallel processing unit 38. The image of the WEB page 41 is held in a memory (not shown) of the parallel processing unit 38.

  On the other hand, the specifying unit 35 analyzes the source code described in the HTML file of the WEB page 41 being displayed. Then, the WEB page presented in parallel with the WEB page 41, that is, the parallel WEB page is specified on the WEB page 41 being displayed.

  The displayed WEB page 41 can specify a parallel WEB page, for example, according to the specific conditions exemplified above. That is, the source code shown in FIG. 5 describes a list display block surrounded by “<UL> ˜ </ UL>”. In this list display block, a list in which "<a href="aaa.bbb.cc/camera/...> (character) </a>" (characters are "AA" to "DD") is described. There are items (<LI> to </ LI>), and it can be determined that links are set for the characters “AA” to “DD” displayed (presented) on the WEB page 41. The link destinations set in the characters “AA” to “DD” are HTML files “aa.html”, “bb.html”, “cc.html”, “dd.html” specified by the URL. Yes, each is determined as an object to be displayed as a WEB page (condition 1).

  By the way, from the URL of the WEB page being displayed, it can be determined that “aa.html” is that of the WEB page 41 being displayed, and the current directory can be acquired. In this example, the current directory is “aaa.bbb.cc/camera”.

  Since the link destination URL is described below “href =”, the storage directory of “bb.html”, “cc.html”, and “dd.html” is “aaa.bbb.cc/camera”. I understand that. Therefore, it is determined that the current directory and the storage directory of “bb.html”, “cc.html”, and “dd.html” are the same (condition 2). Even when the URL is described by a relative path, the directory can be known according to the rules of HTML description.

  Accordingly, the WEB page indicated by the URL designating “bb.html”, “cc.html”, and “dd.html” are all determined to satisfy the exemplified specific conditions (conditions 1 and 2). . As a result, URLs "http://aaa.bbb.cc/camera/bb.html", "http://aaa.bbb.cc/camera/cc.html", "http://aaa.bbb.cc/ Each WEB page specified by “camera / dd.html” is specified as a parallel WEB page. Note that it is also possible to specify a parallel WEB page by making a similar determination even when a link such as “<li class =" on "> AA </ li>” is described and the character “AA” is not set. it can.

  In this example, each WEB page indicated by the URL designating “bb.html”, “cc.html”, and “dd.html” specified as described above also satisfies the above condition 3 Therefore, it can also be specified that they are presented in parallel.

  For example, when it is determined that there is a parallel WEB page as described above, each URL designating the parallel WEB page is sent to the control unit 30. The control unit 30 sequentially sends each URL from the specifying unit 35 to the WEB server 13 via the first communication unit 31. At this time, the control unit 30 sends a URL that is “1” less than the previously obtained number of displayable pages in the order of description in the source code. This is because a parallel WEB image is displayed together with the WEB page being displayed on the display screen 12a. Then, the WEB data of each WEB page specified by the URL is acquired from the WEB server 13.

  Each time WEB data of a parallel WEB page is received, the WEB data is sent to the rendering unit 37. Thereby, rendering of each parallel WEB page is performed, and the generated images are sequentially sent to the parallel processing unit 38, respectively. Actually, an HTML file specified by a URL is acquired, and an image specified in the HTML file is acquired during rendering.

  When the image of the parallel WEB page is input as described above, the parallel processing unit 38 receives each image of the input parallel WEB page on the side of the image of the displayed WEB page 41 held in the memory. Are sequentially connected in the horizontal direction in the input order, so that one parallel image is created. Thereafter, under the control of the control unit 30, the parallel images are trimmed so as to have the length in the vertical direction of the display screen 12 a (the length of the short side in this example). Thereby, a parallel image is completed.

  After the parallel image is completed by the parallel processing unit 38, the control unit 30 displays, for example, a guide such as “Preparation is complete. Please move closer to the electronic paper” on the terminal screen 14a. The operator moves the portable terminal 14 closer to the electronic paper device 12 again according to this guidance. When the portable terminal 14 comes close to the electronic paper device 12 by this operation, power is supplied to the electronic paper device 12 as described above, and the electronic paper device 12 is activated.

  A parallel image is transmitted from the second communication unit 32 to the communication unit 21. The parallel images received by the communication unit are sent to the writing unit 22 and displayed on the display screen 12a. Thereby, the WEB page displayed on the terminal screen 14a and each WEB page presented in parallel to the WEB page are displayed on the display screen 12a, and the operator can view each WEB page collectively.

  When the WEB page 41 is displayed on the terminal screen 14a as described above, as shown in FIG. 6, the camera “AA” displayed on the terminal screen 14a is introduced on the display screen 12a of the electronic paper device 12. The image 51 of the WEB page 41 to be displayed and the images 52a to 52c of each WEB page introducing the cameras “BB” to “DD” presented in parallel on the WEB 41 are displayed side by side. Each of the images 51, 52a to 52c has the same width as that displayed on the terminal screen 14a, and the display screen 12a is longer in the vertical direction than the terminal screen 14a. Therefore, a range wider than the range displayed on the terminal screen 14a is displayed. When the operator views the parallel image on the display screen 12a, the scale is the same as that on the terminal screen 14a, and the layout is maintained on the terminal screen 14a, so there is no sense of incongruity and the necessary information can be obtained immediately. Can be found.

  In the WEB page 41 shown in FIG. 4, a link to the parallel WEB page is set in the characters in the tab 41a. However, the method of presenting the parallel WEB page is not limited to this, and the text of the WEB page includes The link may be set to the arranged character, button, image, or the like.

  For example, in the example shown in FIG. 7, characters such as “company outline”, “recruitment type (office work)”, “recruitment type (technical type)”, “application method”, etc., which are arranged in the text of the WEB page 61. Each of the buttons (images) 61e labeled 61a to 61d and “MAP” is set with a parallel WEB link. When an operation for displaying a parallel image on the electronic paper device 12 is performed in a state where the WEB page 61 is displayed on the terminal screen 14a, an image 62 corresponding to the WEB page 61 being displayed is displayed as shown in FIG. And a parallel image 64 in which a map linked to the “company overview”, “MAP” button (image) 61e, and images 63a to 63c of each WEB page of “recruitment type (office work)” are displayed on the display screen 12a. Is done. In this example, since the number of displayable pages is “4”, images of the WEB pages of “recruitment job type (technical)” and “application method” which are the sixth page are displayed. Not.

  FIG. 9 to FIG. 11 show examples in which there are two groups on the WEB page being displayed in parallel, and one group is selected to generate a parallel image according to the operation history. It is shown.

  The WEB page 71 shown in FIG. 9 is a top page introducing the camera “AA” of the “digital camera XX series”, and “AA” is displayed on the tab 71a thereof. Along with the “AA” tab 71a, tabs 71a for the cameras “BB”, “CC”, and “DD” are displayed. In the characters “BB”, “CC”, and “DD” in the tab 71a, links to the top pages of the WEB pages that introduce the corresponding cameras are set. Therefore, the 1st group which presents the WEB page as a top page in parallel by these is comprised.

  Further, on the WEB page 71, that is, the top page introducing the camera “AA”, for example, characteristics of the camera are displayed, and item characters “specification”, “option”, and “support” are displayed. It is like that. In each item character, a link to a WEB page describing the contents shown for the camera “AA” is set. Therefore, the second group that presents in parallel the WEB pages having the contents related to the camera “AA” is configured.

  As for the “specification”, “option”, and “support” WEB pages of the camera “AA”, tabs 71a of “AA” to “DD” are displayed as well as the top page, and “specification”, “Option” and “Support” item characters are displayed, and links are set in the same manner. A link to the top page of the camera “AA” is set in the character “AA” in the tab 71a on the “specification”, “option”, and “support” WEB pages of the camera “AA”.

  The other top pages introducing the cameras “BB” to “DD” are the same as the top page of the camera “AA”. For example, on the top page of the camera “BB”, tabs “AA” to “DD” are displayed side by side. The characters “AA”, “CC”, and “DD” in those tabs are set with links to the top page of the WEB pages that introduce the corresponding cameras, and the WEB page as the top page is arranged in parallel. A first group to be presented is configured. In addition, on the top page introducing the camera “BB”, the item characters “specification”, “option”, and “support” are displayed, and the contents shown for the camera “BB” are described in each item character. A link to the WEB page is set. Accordingly, the second group that presents in parallel the WEB pages having the contents related to the camera “BB” is configured.

  In this example, when a parallel display instruction is issued, a parallel image including a first group of parallel WEB pages is generated in accordance with an operation immediately before the operation for returning to the displayed WEB page, or the first The control unit 30 determines whether to generate a parallel image including two groups of parallel WEB pages.

  For example, the top page introducing the camera “BB” is displayed on the terminal screen 14a, the item character “specification” is selected, and the web page describing the “specification” of the camera BB is displayed. When the character “BB” in the tab 71a is selected on the WEB page to display the top page, the previous operation for returning to the top page of the camera BB is the second group WEB for the camera BB. An operation to display the page is performed.

  For this reason, when a parallel display instruction is issued in this display state, as shown in FIG. 10, a parallel image composed of the images 73 and 74a to 74c of the top page and the parallel web page of the second group for the camera BB is displayed. This is generated and displayed on the display screen 12 a of the electronic paper device 12. This is because the previous operation for returning to the top page of the camera BB is an operation for displaying the WEB page of the second group for the camera BB.
