 Technical field

 [0001] The present invention relates to a video display device and a computer program for displaying video.

 Background art

 Japanese Patent Application Laid-Open No. 2001-273702 describes a video display device that functions as a so-called screen saver. When this video display device functions as a screen saver, it sequentially reproduces a plurality of videos (moving pictures, moving pictures) designated in advance by the user one by one.

 Disclosure of the invention

 Problems to be solved by the invention

 [0003] The screen saver is required to perform a display that the user feels fun. In order to do so, it is necessary to devise measures that will not let users get bored. However, the screen saver described in Japanese Patent Laid-Open No. 2001-273702 has a high possibility of getting bored immediately because only one image is displayed at a time. Therefore, it is conceivable to change the screen saver so that a plurality of images can be displayed at the same time, and the possibility of getting bored is reduced.

 [0004] The simplest technique capable of simultaneously displaying a plurality of videos is to perform video playback using video data simultaneously for a plurality of video data. However, in this case, a high processing capability is required for the video display device. As another method, video data representing one video in which a plurality of videos are spatially arranged is prepared in advance, and a plurality of videos are played back simultaneously by playing back video using this video data. It can be seen that Since the same display results can be obtained by playback using the same video data, a large number of videos can be displayed to realize a variety of video displays that can sufficiently reduce the possibility of getting bored. It is necessary to prepare data in advance.

[0005] The present invention has been made in view of the above-described circumstances, and does not require high processing capability, and can display a plurality of videos at the same time, without preparing a large number of video data in advance. An image display device and a computer program capable of displaying various images provide.

Means for solving the problem

 The present invention will be described below. In addition, in order to facilitate understanding of the present invention, the power of appending reference numerals on the attached drawings in parentheses, the present invention is not limited to the illustrated form.

 The present invention provides an original whole image for reproducing an original whole image (BM) having a certain reproduction time, which occupies an image display region (R) having a plurality of partial regions that are arranged in advance and do not overlap each other. A storage unit (170) that stores data (171), and the original whole video data (171) is read from the storage unit (170), and a plurality of partial videos (SM;! To SM4), the rearrangement unit (150) generates rearranged video data (181) for reproducing the rearranged video (AM) by processing so that the arrangement of the original whole video (BM) is switched. , SA1), and a video playback unit (150, 160, 120, SA2) that plays back the rearranged video (AM) using the rearranged video data (181). The rearranged post-screen by the operation unit (140) for outputting the recorded data and the video reproduction unit (150, 160, 120, SA2). When specific data is output from the operation unit (140) during playback of a video, a stop control unit (150) that stops playback of the rearranged video by the video playback unit (150, 160, 120, SA2) SB), and the playback time of each of the plurality of partial videos (SM;! To SM4) is the same as the playback time of the original whole video (BM), and the plurality of partial videos (SM) ; To SM4) each provide a video display device (100) characterized by occupying a plurality of the partial areas that do not overlap each other when the original whole video (BM) is reproduced.

As an aspect of the video display device (100), an aspect in which the entire original video data (171) is stored in advance in the storage unit (170), or a part of the original entire video data (171) is stored in the storage unit ( 170) when the rearrangement unit (150, SA1) starts reading the original whole video data (171) when it is not stored in the video, the video after all the rearranged video data (181) is generated A mode in which the playback unit (150, 160, 120, SA2) starts playback using the rearranged video data (181), and a video playback unit when a part of the rearranged video data (181) is not generated. (1 50, 160, 120, SA2) starts playback using the rearranged video data (181) Embodiments can be illustrated.

 In addition, the original whole video data (171) is processed and rearranged so that the arrangement in the original whole video (BM) of the plurality of partial videos (SM;! To SM4) included in the original whole video (BM) is switched. The mode for generating the data (181) is the mode for generating the rearranged video data (181) for playing back the rearranged video (AM) including only a plurality of partial videos (SM;! To SM4). Or rearranged video data (181) for playing back a rearranged video (AM) including a plurality of partial videos (SM;! To SM4) and videos other than a plurality of partial videos (SM;! To SM4). ) Can be exemplified. In addition, “playback time” for video means the length in the time axis direction.

 In this video display device (100), the video playback unit (150, 160, 120, SA2) reproduces the rearranged video data (181) using the rearranged video data (181), thereby Video (SM;! To SM4) is displayed at the same time. Therefore, according to this video display device (100), it is possible to simultaneously display a plurality of videos without requiring high processing capability.

 In this video display device (100), even if the video playback unit (150, 160, 120, SA2) reads the same original whole video data (171), the rearranged video (AM) to be played back is not reproduced. It is not always the same. Therefore, according to this video display device (100), various video displays can be performed without preparing a large number of original whole video data (171) in advance.

 [0007] In the video display device (100), the rearrangement unit (150, SA1) sorts the plurality of partial videos (SM;! To SM4) in processing the original whole video data (171). A boundary image (DM) that is an image of a boundary line may be included in the rearranged image (AM). According to this aspect (100), each of the plurality of partial videos (SM;! To SM4) is easily recognized as an independent video. This contributes to reducing the possibility of getting bored.

[0008] In the aspect (100) or the video display device (100), the original entire video data (171) stored in the storage unit (170) is compression-encoded, and the rearrangement unit (150, SA1) may decode the read original whole video data (171) prior to processing of the original whole video data (171). In this way Since the amount of video data can be reduced, the storage capacity required for the storage unit (170) can be reduced.

[0009] In addition, the present invention reproduces an original entire video (BM) having a plurality of partial images that are arranged in advance and occupy an image display region (R) having a plurality of partial regions that do not overlap each other.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. The specific configuration described below is merely an example, and the present invention includes various forms obtained by modifying this specific configuration.

[0013] [Configuration]

 FIG. 1 is a block diagram showing a configuration of video display apparatus 100 according to the embodiment of the present invention. The hardware configuration of the video display device 100 is the same as that of a general personal computer. That is, the video display device 100 includes a main processor (relocation unit, stop control unit, video playback unit) 150 that performs various processes, an operation unit 140 that outputs operation data corresponding to the operation when operated by the player, and a command. Display control unit 160 (video playback unit) that supplies a video signal to the display unit 120 and displays video using the video signal from the display control unit 160. It has a display unit 120, a storage unit 170 for storing various data, and a main memory 180 used as a work area.

The main processor 150 is, for example, one or a plurality of CPUs (Central Processing Units). Specifically, the display unit 120 is a CRT (Cathode Ray Tube), has a rectangular screen 121, and repeats the process of scanning the screen 121 with an electron beam and displaying an image, thereby displaying an image on the screen 121. Is displayed. The operation unit 140 is specifically a keyboard 141 and a pointing device 142. The keyboard 141 has a plurality of keys, and outputs operation data corresponding to the pressed key. The pointing device 142 is a mouse, for example, and outputs operation data corresponding to the moving direction and moving speed. The display control unit 160 includes a video memory 161 and a display processor 162 that store various data for supplying a video signal to the display unit 120. The video memory 161 is realized by, for example, a RAM (Random Access Memory), and a frame buffer FB for storing image data for one screen (one frame) is secured in the storage area. A display processor (Graphics Processing Unit) 162 receives a command, performs image processing according to the command, and supplies a video signal to the display unit 120. The video signal is supplied from the display processor 162 by reading a screen image data from the frame buffer FB and supplying it to the display unit 120 for a predetermined time (for example, about 1/30 second or about 1 / second). It is realized by repeatedly executing at intervals of 60 seconds. Further, when the image processor ends, the display processor 162 supplies an end notification indicating that to the main processor 150.

Yes

 [0016] One type of command supplied to the display processor 162 is a drawing command that orders image drawing. Image processing according to the drawing command is drawing processing. Drawing processing is processing that writes image data to the frame buffer FB. One type of drawing process is a video playback process for playing back video, and one type of drawing command is a video playback command that orders video playback processing. The video reproduction command includes video designation data for designating video data for reproducing the video and area designation data for designating a rectangular image display area occupied by the video reproduced using the video data. In the video playback process, the display processor 162 displays a plurality of pieces of image data for displaying a plurality of rectangular images constituting a video to be played back using the video data designated in the video designation data (a plurality of image data described later). A number of partial videos SM (corresponding to! ~ SM4) are sequentially written to the storage area of the frame buffer FB corresponding to the image display area specified in the area specification data one by one.

 [0017] Further, as one type of command supplied to the display processor 162, there is a stop command for commanding stop of the video playback process being executed. Image processing corresponding to the stop command is stop processing. In the stop process, the display processor 162 stops the video playback process being executed. Therefore, the end notification indicating the end of the stop process also indicates the stop of the video playback process.

[0018] Storage unit 170 (storage unit) does not require a power source to maintain stored contents. The storage area of the storage unit 170 includes a non-rewritable area R1 in which the stored contents cannot be rewritten, and the stored contents. It can be divided into a rewritable area R2 that can be replaced. The non-rewritable area R1 is realized by, for example, ROM (Read Only Memory), and the rewritable area R2 is realized by, for example, a hard disk. In the non-rewritable area R1, an IPL (Initial Program Loader) that is executed when the video display device 100 is started is written. In the rewritable area R2, basic software called by the IPL and a computer program p described later called by the basic software are written. The basic software is software for realizing basic functions such as an operating system in the video display device 100.

In addition, a plurality of original whole video data 171 is stored in the rewritable area R2 of the storage unit 170 (storage unit). Original whole video data 171 is video data for reproducing the original whole video BM, and is compression-coded by VC1 of SMPTE (Society of Motion Picture and Television Engineers). However, as another embodiment, the original entire video data 171 may be compressed by a known moving image compression technique other than VC1. However, as another embodiment, some or all of the entire original video data 171 may be stored in the non-rewritable area R1.

FIG. 2 is a diagram schematically showing the original entire video BM in the video display device 100. As shown in FIG. The original whole image BM includes a plurality of rectangular images F of the same size arranged in the time axis direction, and includes a plurality of partial images SM;! To SM4 having the same length as the original whole image BM in the time axis direction. Each partial image SM;! To SM4 includes a plurality of partial images (rectangular images) of the rectangular image F. In each rectangular image F, multiple partial images do not overlap each other. The arrangement of the partial images in the rectangular image F is common to the plurality of rectangular images F. That is, in the original whole image BM, the plurality of partial images SM;! To SM4 are arranged so as not to overlap each other. Also, the image display area occupied by the video is unchanged during playback. Therefore, a plurality of partial videos SM;! To SM4 continue to occupy a plurality of partial areas that do not overlap each other in the image display area during the reproduction of the original whole video BM.

[0021] The main memory 180 is realized by, for example, a RAM, and requires a power source to hold stored contents. In the main memory 180, the rearranged video data 181 is temporarily stored. The rearranged video data 181 is video data for reproducing the rearranged video AM, and is generated in a rearrangement process described later. In this embodiment, it is actually used for video playback. Only the rearranged video data 181 is displayed.

 [0022] The screen saver program P is used to cause the video display device 100 to perform a standby display process (stalling saving process), and is executed intermittently by the main plug processor 150 executing the basic software. . The standby display process is a process of displaying a standby video on the screen 121 and waiting for a user instruction. The standby video is a video that is suitable for waiting for a user's instruction, for example, a video in which the display content of the image display area changes every moment. The standby display process (execution of the screen saver program P) starts when a predetermined period elapses without a user instruction being input.

 [0023] [Operation]

 FIG. 3 is a flowchart showing standby display processing performed by the main processor 150 of the video display device 100. In the standby display process, the main processor 150 first selects one original whole video data 171 from the plurality of original whole video data 171 stored in the storage unit 170 (step Sl). This selection is performed at random using, for example, a random number.

Next, the main processor 150 performs pseudo parallel video reproduction processing using the selected original whole video data 171 (step S2). The pseudo parallel video playback process is a process of playing back video while making it appear as if multiple videos are being played back simultaneously. In the quasi-parallel video playback process, the main processor 150 performs in parallel a continuous video playback process (step SA) that repeats video playback and an end control process (step SB) that controls the end of the continuous video playback process. Execute.

 [0025] In the continuous video reproduction process, the main processor 150 generates a rearranged video data 181 by rearranging the partial videos SM;! To SM4 based on the selected original whole video data 171 (step S). A1) and the video reproduction process (step SA2) for reproducing the rearranged video AM using the generated rearranged video data 181 are alternately repeated. During this time, the rearranged video AM for screen saving is displayed on the screen 121 as a standby video. Therefore, the video display device 100 can prevent the screen 121 from being burned.

FIG. 4 is a flowchart showing the rearrangement process included in the standby display process. In the reallocation process, the main processor 150 functions as a reallocation unit, and in step S1, The selected original whole video data 171 is read from the storage unit 170 and written to the main memory 182 (step SA11). Hereinafter, the original whole video data 171 written in the main memory 182 is referred to as “selected video data”. Next, the main processor 150 decodes (decompresses) the selected video data using VC1 (step SA12).

 [0027] Next, the main processor 150 determines an arrangement replacement rule for the partial videos SM ;! to SM4 (step SA13). This determination is performed at random using random numbers, for example. As the replacement rule, for example, the rule that the arrangement of the partial video SM1 and the partial video SM4 is exchanged, the arrangement of the partial video SM1 and the partial video SM3 is exchanged, and then the partial video SM3 and the partial video SM4 are replaced. A rule of changing the arrangement can be exemplified.

 Next, main processor 150 functions as a rearrangement unit, processes selected video data, and generates rearranged video data 181 related to rearranged video AM (steps SA14 to SA17). Specifically, first, the main processor 150 sets the first rectangular image F among the plurality of rectangular images F included in the original entire video BM reproduced using the selected video data as the target image (step S1). SA14). Next, the main processor 150 performs processing on the image of interest (step SA15). That is, the selected video data is processed so that the arrangement of the plurality of partial images included in the target image and included in different partial images SM1 to SM4 is replaced according to the determined replacement rule. . Next, the main processor 150 determines whether or not the image of interest is the last rectangular image (step SA16). If the determination result is negative, the main processor 150 sets the next rectangular image after the current image of interest as the image of interest (step SA17), and returns the process to step SA15. On the other hand, if the determination result in step SA16 is affirmative, the rearrangement process ends.

[0029] As is apparent from the power described above, the main processor 150 performs the processing of step SA15 on each rectangular image F. In this way, the selected video data is processed and rearranged so that the arrangement of the partial videos SM;! To SM4 in the original whole video BM reproduced using the selected video data is switched according to the determined replacement rule. Later video data 181. In this embodiment, the main processor 150 generates all of the rearranged video data 181 used in the video playback process described later before starting the video playback process, and Remember me in 180.

 [0030] In the video playback process of step SA2 in FIG. 3, the main processor 150 functions as a video playback unit, and video designation data for designating the rearranged video data 181 and a predetermined image display area R ( The video reproduction command including the area designation data for designating (see FIG. 5) is supplied to the display processor 162 of the display control unit 160. Upon receiving this video playback command, the display processor 162 of the display control unit 160 functions as a video playback unit and performs video playback processing. As a result, the rearranged video AM is reproduced. As a result, for example, the rearranged video AM shown in FIG. 5 is displayed in the image display area R of the screen 121. After step SA2, the process returns to step SA1, and the main processor 150 generates new rearranged video data 181. Therefore, in the next step SA2, a moving image that is different from the previous step SA2 is reproduced.

 FIG. 5 is a diagram showing an example of an image displayed on the screen 121 of the video display device 100 in the standby display process. As shown in this figure, the rearranged video AM is divided into a plurality of partial videos SM;! To SM4 that are not simply the images of the partial video SM;! It is an image including a boundary image DM that is a frame line, that is, an image of the boundary line. That is, the processing in step SA15 is performed so that the rearranged video data 181 for reproducing the rearranged video AM including the boundary video DM is generated. The boundary image DM spatially extends along the outline of each of the plurality of partial images SM ;! to SM4, and has the same playback time as the rearranged image AM in terms of time. In addition, from the viewpoint of clarifying the division of the plurality of partial videos SM ;! to SM4, it is desirable to employ a video in which a plurality of images having the same contents are arranged in the time axis direction as the boundary video DM.

 [0032] In addition, when the main processor 150 receives the end notification corresponding to the video playback command supplied to the display processor 162 in the video playback processing of step SA2, that is, after the rearrangement designated by the video playback command. When the playback of the video AM after rearrangement using the video data 181 is finished or stopped, the video playback processing in step SA2 is finished.

[0033] On the other hand, in the end control process of step SB, the main processor 150 functions as a stop control unit, and the stop data is output until stop data is output from the operation unit 140 to stop the display of the standby video. Repeat the determination of whether or not it has been output (step SB1). And If the determination result in step SB1 is affirmative, the main processor 150 functions as a stop control unit and performs an end process to end the continuous video playback process (step SB2). In the termination process, the main processor 150 stops the rearrangement process if the rearrangement process is being executed, and supplies a stop instruction to the display processor 162 if the video reproduction process is being performed. Wait until an end notification corresponding to the instruction is received from the display processor 162. In other words, when stop data is output from the operation unit 140 while the video playback process is being performed by the display processor 162, the main processor 150 displays the display status of the rearranged video AM at that time (for example, the screen 121). The video playback processing by the display processor 162 is stopped regardless of the area after the rearrangement of the video AM. As a result, the playback of the rearranged video BM (standby video) is stopped.

 [0034] Then, when the main processor 150 stops the rearrangement process or receives the end notification, the main processor 150 ends the end process. When the end process ends, the continuous video playback process and the end control process, that is, the pseudo parallel video playback process ends, and the standby display process ends.

 [0035] [Effect]

 As described above, in the video display device 100, the main processor 150 selects one of the plurality of original whole video data 171 stored in the storage unit 170 as the selected video data, and this selected video data And rearranged video data 181 for reproducing the rearranged video AM is generated by processing the partial video SM;! To SM4 so that the arrangement in the original whole video BM is switched. The main processor 150 uses the rearranged video data 181 to play back the rearranged video AM, while the stop data is output from the operation unit 140 during the playback of the rearranged video AM. Stop playing the video after rearrangement

[0036] The rearranged video AM reproduced using the rearranged video data 181 includes a plurality of partial videos SM ;! to SM4. Therefore, in the video display device 100, a plurality of partial videos SM ;! to SM4 are simultaneously displayed using one post-repositioned video data 181. Therefore, according to the video display device 100, it is possible to simultaneously display a plurality of videos without requiring high processing capability. [0037] Also, in the video display device 100, even if the same original whole video data 171 is selected a plurality of times, the replacement rule of the arrangement of the partial videos SM ;! Determined. Therefore, the probability that the rearranged video AM is the same is suppressed to a low level. Therefore, according to the video display device 100, it is possible to perform video display with at least the number of original whole video data 171 stored in advance in the storage unit 170.

 [0038] In the video display device 100, the main processor 150 (rearrangement unit), in the processing of the selected video data in step SA15, the video of the boundary line that divides the plurality of partial videos SM;! The boundary image DM which is is included in the image AM after the rearrangement. Therefore, the rearranged video AM includes the boundary video DM, and on the screen 121, the plurality of partial areas occupied by the plurality of partial videos SM ;! to SM4 are separated from each other. Therefore, according to the video display device 100, each of the plurality of partial videos SM ;! to SM4 is easily recognized as 1S independent videos. This contributes to reducing the possibility of getting bored by the user.

 In video display device 100, original whole video data 171 stored in storage unit 170 (storage unit) is compression-encoded, and main processor 150 (relocation unit) performs processing in step SA15. Prior to the processing of the selected video data, this selected video data is decoded. Therefore, the amount of video data prepared in advance, that is, the capacity required for the rewritable area R2 can be reduced. Further, in the video display device 100, the compression coding power is performed by VC1 for each original whole video BM, not for every partial video SM;! ~ SM4. Since VC1 performs intra-frame coding, this contributes to improved compression efficiency.

 [0040] [Modification]

As another embodiment, the boundary image DM may not be used. In this embodiment, the selected video data is processed so that the arrangement of the plurality of partial videos SM;! To SM4 in the original whole video BM is switched, and the plurality of partial videos SM;! To SM4 and the boundary video DM are The rearranged video data 181 for playing back the rearranged video AM is generated. However, the rearranged video data for reproducing the rearranged video including only the plurality of partial videos SM;! To SM4 may be generated. About this variation, This will be described with reference to FIG.

 FIG. 6 is a diagram showing a part of a flowchart of the rearrangement process performed by the main processor 150 of the video display device according to the modification of the present embodiment. In this figure, step SC corresponds to step SA15 (Fig. 4). In step SC, as in step SA15, the partial images SM;! To SM4 included in the image of interest that are different from each other are replaced according to the determined replacement rules for the arrangement power in the image of interest of the partial images included in! The selected video data is processed, but unlike step SA15, rearranged video data that does not include video data for playing the boundary video DM is generated. Other features of this rearrangement process are the same as the rearrangement process of FIG. 4 described above.

 As another embodiment, the video reproduction command may be supplied to the display processor 162 after the rearranged video data is compression-encoded. However, in this case, the display control unit 160 needs to be configured so that the display processor 162 can decode the compressed and encoded video data. As another embodiment, the rearranged video data that has not been compression-encoded may be stored in the storage unit 170, and the process of step SA12 (decoding of the selected video data) may be skipped. If it is possible to adopt video compression technology that can change the arrangement of the partial video without decoding the compression-encoded video data, the process in step SA12 is skipped in that case as well. The rearranged video data may be generated from the original whole video data that has been compressed and encoded.

 In the present embodiment, the arrangement of the plurality of partial videos SM ;! to SM4 can be changed between the arbitrary partial videos SM ;! to SM4. However, the present invention is not limited to this. For example,

The partial video SM1 and the second partial video SM2 are grouped together, the third partial video SM3 and the fourth partial video SM4 are grouped together, and the arrangement of the partial video can be changed within the same group. As a form that only allows.

[0044] As another embodiment, so-called streaming reproduction may be supported. That is, in the present embodiment, the entire original video data 171 read in the rearrangement process is the force S stored in the storage unit 170 before the start of the process, and in the other embodiments, the original entire video data 171 The rearrangement process may be started when a part of the data 171 is not stored in the storage unit 170. Similarly, in the present embodiment, the entire rearranged video data 181 used in the video playback process is generated before the start of the process. In other embodiments, the rearranged video data 181 is used in the video playback process. When part of the rearranged video data 181 has not been generated, use the rearranged video data 181! /, Or start playback! /.

 As another embodiment, the main processor 150 may serve as the display processor 162, and the main memory 180 may serve as the video memory 161. In this case, the main processor 150 executes a program for performing processing similar to the processing performed by the display processor 162 in parallel with the program. As another embodiment, for example, a liquid crystal display or a video projector is used as the display unit. In a configuration using a video projector, a screen on which an image is projected corresponds to the screen 121.

 [0046] As another embodiment, instead of the continuous video playback process in step SA, a single video playback process in which video playback is performed only once may be performed. In this case, the main processor 150 performs a rearrangement process (step SA1) for generating all of the rearranged video data 181 by rearranging the partial videos SM;! Then, the video reproduction process (step SA2) for reproducing the entire rearranged video AM using the rearranged video data 181 is performed, and finally, the process waits until the end process of step SB2 is completed. As a result, the moving image is reproduced only once.

 As another embodiment, a game machine (computer) that allows a player to play a game may be used as a video display device. This video display device displays the rearranged video while waiting for the player's operation while the game is not being played. An example of the operation unit of the video display device is a start button that outputs start data instructing the start of the game when pressed by the player. If the game machine is an arcade game machine that allows the player to play the game for a fee, it is possible to use a detection unit that detects detection of coins and other payments and outputs detection data as the operation unit. is there.
