  First, the animation data of each button image will be described. FIG. 12 is a diagram showing animation data of each button image. In the case of the present embodiment, as shown in FIG. 12, the animation data of each button image is data having a length (reproduction time) of 120 frames. Hereinafter, the nth frame is referred to as an “nth frame”. Here, the frame interval is 1/60 seconds.

  The portions from the first frame to the 30th frame are animation data for continuing to display the button image in a non-selected state. More specifically, animation data for continuing to display the button image in a state where the surface is not hatched and a shadow 76 is added to the first to 30th frames. It is. For this reason, when the button image is not selected, the portions from the first frame to the 30th frame of the animation data of the button image are repeatedly reproduced. Hereinafter, the portion from the first frame to the 30th frame is referred to as “first animation data”.

  The portions from the 31st frame to the 60th frame are animation data for displaying a state in which the state of the button image changes from the non-selected state to the selected state. More specifically, the portion from the 31st frame to the 60th frame displays “after the button image shines, the shadow 76 of the button image gradually disappears and a diagonal line gradually appears on the surface of the button image”. This is animation data. For this reason, when the state of the button image changes from the non-selected state to the selected state, the portion from the 31st frame to the 60th frame of the animation data of the button image is reproduced. In addition, when the reproduction from the 31st frame to the 60th frame is completed, the portion from the 61st frame to the 90th frame is repeatedly reproduced. Hereinafter, the part from the 31st frame to the 60th frame is referred to as “second animation data”.

  The portions from the 61st frame to the 90th frame are animation data for continuously displaying the button image in the selected state. More specifically, the portions from the 61st frame to the 90th frame are animation data for continuing to display the button image in a state where the surface is hatched and the shadow 76 is not added. . For this reason, when the button image is selected, the portion from the 61st frame to the 90th frame of the animation data of the button image is repeatedly reproduced. Hereinafter, the portion from the 61st frame to the 90th frame is referred to as “third animation data”.

  The portions from the 91st frame to the 120th frame are animation data for displaying the state of the button image changing from the selected state to the non-selected state. More specifically, the portion from the 91st frame to the 120th frame displays “after the button image shines, the diagonal lines on the surface of the button image gradually disappear and the shadow 76 of the button image gradually occurs”. This is animation data. For this reason, when the state of the button image changes from the selected state to the non-selected state, the portions from the 91st frame to the 120th frame of the animation data of the button image are reproduced. When the playback from the 91st frame to the 120th frame is completed, the portion from the 1st frame to the 30th frame is repeatedly played back. Hereinafter, the portion from the 91st frame to the 120th frame is referred to as “fourth animation data”.

  In the case of the present embodiment, the length (number of frames) of the second animation data of each button image is the same as the length of the fourth animation data of each button image (30 frames in the case of the present embodiment). Is characterized by being unified. This point will be described later.

  Next, the current reproduction position data of the animation data of each button image will be described. FIG. 13 shows an example of this data. This data indicates the current playback position of the animation data of each button image. In the case of the present embodiment, this data indicates what number frame of animation data of each button image is being reproduced. Hereinafter, updating the current playback position of the button image animation data is referred to as “updating the current playback position of the button image”.

  Next, script data (program) for reproduction control of animation data of each button image will be described. This script data is a program of processing executed every predetermined time (in the case of the present embodiment, 1/60 seconds) while the operation screen is displayed based on moving image data. For example, the script data defines a process to be executed when each button image is instructed. FIG. 14 is a flowchart showing script data processing.

  As shown in FIG. 14, first, the microprocessor 44 advances the current reproduction position of the animation data of each button image by one frame (S101). Note that the button image that has not been selected is updated to the first frame when the current playback position is the 30th frame in order to repeatedly reproduce the first animation data. Similarly, for the selected button image, in order to repeatedly reproduce the third animation data, when the current reproduction position is the 90th frame, it is updated to the 61st frame.

  Thereafter, the microprocessor 44 determines whether or not the continuous playback button 60 has been instructed (S102). Whether or not a button image has been instructed is determined based on the display position of the button image and the pressed position information output from the touch panel 22b. If it is determined that the continuous playback button 60 has been instructed, the microprocessor 44 executes a continuous playback button process (S103). FIG. 15 is a flowchart showing continuous playback button processing. As described above, when the playback mode is changed from the chapter playback mode to the continuous playback mode, the operation screen returns to the state shown in FIG. Therefore, the continuous playback button process is a process for returning the operation screen to the state shown in FIG. 4 when the playback mode is changed from the chapter playback mode to the continuous playback mode.

  As shown in FIG. 15, the microprocessor 44 first determines whether or not the reproduction mode flag is 0 (S201). When the playback mode flag is 0, the playback mode is already the continuous playback mode, and therefore it is not necessary to execute the following processing (S202 to S209). Therefore, this process ends.

  On the other hand, when the playback mode flag is not 0, the microprocessor 44 updates the current playback positions of the continuous playback button 60 and the chapter playback button 62 (S202). That is, in order to change the state of the continuous playback button 60 to the selected state, the current playback position of the continuous playback button 60 is updated to the 31st frame, which is the start position of the second animation data. Further, in order to change the state of the chapter playback button 62 to the non-selected state, the current playback position of the chapter playback button 62 is updated to the 91st frame which is the start position of the fourth animation data. Further, the microprocessor 44 updates the reproduction mode flag to 0 (S203).

  Thereafter, the microprocessor 44 reads the current chapter number (n) (S204). Then, the microprocessor 44 updates the current playback position of the nth chapter button to the 91st frame in order to change the state of the nth chapter button to a non-selected state (S205). Further, the microprocessor 44 updates the current chapter number to 0 (S206).

  Thereafter, the microprocessor 44 determines whether or not the reproduction state flag is 0 (S207). If the reproduction state flag is not 0, the microprocessor 44 updates the current reproduction positions of the reproduction button 72 and the stop button 74 (S208). That is, in order to change the state of the playback button 72 to the non-selected state, the current playback position of the playback button 72 is updated to the 91st frame. In order to change the state of the stop button 74 to the selected state, the current playback position of the stop button 74 is updated to the 31st frame. Further, the microprocessor 44 updates the reproduction state flag to 0 (S209). Thus, the continuous playback button process ends.

  When it is determined in S102 of FIG. 14 that the continuous playback button 60 has not been instructed, the microprocessor 44 determines whether or not the chapter playback button 62 has been instructed (S104). If it is determined that the chapter playback button 62 has been instructed, the microprocessor 44 executes a chapter playback button process (S105). As described above, when the playback mode is changed from the continuous playback mode to the chapter playback mode, the operation screen returns to the state shown in FIG. Therefore, the chapter playback button process is a process for returning the operation screen to the state shown in FIG. 7 when the playback mode is changed from the continuous playback mode to the chapter playback mode.

  The chapter playback button process is similar to the continuous playback button process (see FIG. 15). The chapter playback button processing is different from the continuous playback button processing in the following points. That is, in S201, it is determined whether or not the playback mode flag is 1. In S202, the current playback position of the continuous playback button 60 is updated to the 91st frame, and the current playback position of the chapter playback button 62 is updated to the 31st frame. In S203, the playback mode flag is updated to 1.

  If it is determined in S104 of FIG. 14 that the chapter playback button 62 has not been instructed, the microprocessor 44 determines whether or not the chapter button has been instructed (S106). If it is determined that the chapter button has been instructed, the microprocessor 44 executes a chapter button process (S107). FIG. 16 is a flowchart showing chapter button processing.

  As shown in FIG. 16, first, the microprocessor 44 reads the current chapter number (n) (S301). Further, the microprocessor 44 acquires the chapter number (m) of the instructed chapter button (S302). Thereafter, the microprocessor 44 updates the current playback position of the nth chapter button and the mth chapter button (S303). That is, in order to change the state of the nth chapter button to the non-selected state, the current playback position of the nth chapter button is updated to the 91st frame. Further, in order to change the state of the m-th chapter button to the selected state, the current playback position of the m-th chapter button is updated to the 31st frame. Thereafter, the microprocessor 44 updates the current chapter number to m, and updates the current playback position of the video to the first frame of the m-th chapter (S304). The chapter button process is thus completed.

  When it is determined in S106 of FIG. 14 that the chapter button is not instructed, the microprocessor 44 determines whether or not the playback button 72 is instructed (S108). If it is determined that the play button 72 has been instructed, the microprocessor 44 executes a play button process (S109). FIG. 17 is a flowchart showing the playback button process. The reproduction button process is a process for changing the operation screen to the state shown in FIG. 5 or FIG.

  As shown in FIG. 17, first, the microprocessor 44 determines whether or not the reproduction state flag is 0 (S401). The case where the playback state flag is not 0 is a state where the playback button 72 has already been selected, and therefore it is not necessary to execute the following processing (S402 to S410). Therefore, this process ends. On the other hand, when the reproduction state flag is 0, the microprocessor 44 determines whether or not the reproduction mode flag is 0 (S402).

  When the reproduction mode flag is 0, the microprocessor 44 determines whether or not the current chapter number (n) is 1 (S403). If the current chapter number (n) is not 1, the microprocessor 44 updates the current playback position of the nth chapter button and the first chapter button 64 (S404). That is, in order to change the state of the nth chapter button to the non-selected state, the current playback position of the nth chapter button is updated to the 91st frame. In order to change the state of the first chapter button 64 to the selected state, the current playback position of the first chapter button 64 is updated to the 31st frame. Further, the microprocessor 44 updates the current chapter number to 1, and updates the current playback position of the video to the first frame of the first chapter (S405). The continuous playback mode is a mode in which playback is performed in order from the first chapter. For this reason, if the first chapter is not selected when the playback button 72 is instructed, it is necessary to automatically select the first chapter. For this reason, the processes of S403 to S405 are executed.

  On the other hand, if the playback mode flag is not 0, the microprocessor 44 determines whether or not the current chapter number (n) is 0 (S406). If the current chapter number (n) is 0, the microprocessor 44 updates the current playback position of the first chapter button 64 to the 31st frame in order to change the state of the first chapter button to the selected state (S407). . Further, the microprocessor 44 updates the current chapter number to 1, and updates the current playback position of the video to the first frame of the first chapter (S408). The chapter playback mode is a mode in which only one chapter is played back. For this reason, if any chapter is not selected when the playback button 72 is instructed, it is necessary to automatically select any chapter (here, the first chapter). For this reason, the processes of S406 to S408 are executed.

  After the processes of S402 to S408 are executed, the microprocessor 44 updates the current playback positions of the playback button 72 and the stop button 74 (S409). That is, in order to change the state of the playback button 72 to the selected state, the current playback position of the playback button 72 is updated to the 31st frame, which is the start position of the second animation data. Further, in order to change the state of the stop button 74 to the non-selected state, the current playback position of the stop button 74 is updated to the 91st frame which is the start position of the fourth animation data. Further, the microprocessor 44 updates the reproduction state flag to 1, and updates the standby time counter to 0 (S410). Thus, the playback button process ends. As will be described later (see S604 to S610 in FIG. 19), in this case, the reproduction of the video is waited until the reproduction of the second animation data of the reproduction button 72, the fourth animation data of the stop button 74, and the like is completed. Is started. The standby time counter is used to determine whether or not the reproduction of the animation data has been completed.

  If it is determined in S108 in FIG. 14 that the play button 72 has not been instructed, the microprocessor 44 determines whether or not the stop button 74 has been instructed (S110). If it is determined that the stop button 74 has been instructed, the microprocessor 44 executes a stop button process (S111). FIG. 18 is a flowchart showing stop button processing. The stop button process is a process for returning the operation screen to the state shown in FIG. 4 or FIG.

  As shown in FIG. 18, first, the microprocessor 44 determines whether or not the reproduction state flag is 0 (S501). The case where the reproduction state flag is 0 means that the stop button 74 has already been selected, and therefore it is not necessary to execute the following processing (S502 to S506). Therefore, this process ends.

  On the other hand, when the reproduction state flag is not 0, the microprocessor 44 reads the current chapter number (n) (S502). Then, the microprocessor 44 updates the current playback position of the nth chapter button to the 91st frame in order to change the state of the nth chapter button to the non-selected state (S503). Further, the microprocessor 44 updates the current chapter number to 0 (S504). Thereafter, the microprocessor 44 updates the current playback position of the playback button 72 and the stop button 74 (S505). That is, in order to change the state of the playback button 72 to the non-selected state, the current playback position of the playback button 72 is updated to the 91st frame. In order to change the state of the stop button 74 to the selected state, the current playback position of the stop button 74 is updated to the 31st frame. Further, the microprocessor 44 updates the reproduction state flag to 0 (S506). Thus, the stop button process ends.

  After the processing of S101 to S111 in FIG. 14 is executed, the microprocessor 44 updates the operation screen by reproducing the animation data of each button image (S112). In this case, the animation data of each button image is reproduced based on the current reproduction position data (see FIG. 13) of the animation data of each button image.

[Still image data storage]
The still image data storage unit 85b is realized by, for example, a VRAM. The still image data storage unit 85b stores still image data representing an operation screen. In the present embodiment, the still image data storage unit 85b stores the still image data of the operation screen acquired by the still image data acquisition unit 90.

[Operation screen display area]
The operation screen display unit 88 is realized by, for example, the first liquid crystal display unit 22a. The operation screen display unit 88 displays an operation screen.

[First operation screen display control unit]
The first operation screen display control unit 86 is realized by, for example, the microprocessor 44 and the image processing unit 48. The first operation screen display control unit 86 displays an operation screen on the operation screen display unit 88 based on the moving image data of the operation screen stored in the moving image data storage unit 85a. More specifically, the first operation screen display control unit 86 displays the operation screen on the operation screen display unit 86 by reproducing the animation data of each button image. Hereinafter, an operation screen displayed based on the moving image data of the operation screen stored in the moving image data storage unit 85a is referred to as a “dynamic operation screen”.

[Still image data acquisition unit]
The still image data acquisition unit 90 is realized by the microprocessor 44 and the image processing unit 48, for example. The still image data acquisition unit 90 captures the operation screen displayed on the operation screen display unit 88 at a predetermined timing while the dynamic operation screen is displayed on the operation screen display unit 88. The image captured by the still image data acquisition unit 90 (still image data of the operation screen) is stored in the still image data storage unit 85b.

[Second operation screen display control unit]
The second operation screen display control unit 92 is realized by, for example, the microprocessor 44 and the image processing unit 48. The second operation screen display control unit 92 displays an operation screen on the operation screen display unit 88 based on the still image data of the operation screen stored in the still image data storage unit 85b. More specifically, the second operation screen display control unit 92 displays still image data of the operation screen on the operation screen display unit 88. Hereinafter, an operation screen displayed based on still image data of the operation screen stored in the still image data storage unit 85b is referred to as a “static operation screen”.

[Determining part]
The determination unit 94 is realized by the microprocessor 44, for example. The determination unit 94 determines whether or not the execution state of the video reproduction process is a predetermined state. For example, the determination unit 94 determines whether or not the video playback control unit 82 is executing a video playback process. In other words, the determination unit 94 determines whether a video is being displayed on the video display unit 84. The determination by the determination unit 94 is executed based on video reproduction control data stored in the video data storage unit 80.

[Switching section]
The switching unit 96 is realized by the microprocessor 44 and the image processing unit 48, for example. The switching unit 96 switches between a state where the dynamic operation screen is displayed on the operation screen display unit 88 and a state where the static operation screen is displayed on the operation screen display unit 88 based on the determination result of the determination unit 94. . In the present embodiment, when the video playback control unit 82 is not executing video playback processing (when video is not being displayed on the video display unit 84), a dynamic operation screen is displayed on the operation screen display unit 88. On the other hand, when the video playback control unit 82 is executing video playback processing (when video is being displayed on the video display unit 84), a static operation screen is displayed on the operation screen display unit 88.

  Next, processing for realizing the functional blocks described above will be described. 19 to 21 show processing executed by the video reproduction device 10 every predetermined time (in this embodiment, 1/60 seconds) after the dynamic operation screen is first displayed on the first liquid crystal display unit 22a. FIG. The microprocessor 44 executes the processes shown in FIGS. 19 to 21 in accordance with the program stored in the memory card 40.

  First, the microprocessor 44 (determination unit 94) determines whether or not the reproduction state flag is 0 (S601). When the reproduction state flag is 0, the microprocessor 44 (first operation screen display control unit 86, switching unit 96) continues to display the dynamic operation screen (S602). That is, the state where the dynamic operation screen is displayed on the first liquid crystal display unit 22a is maintained.

  On the other hand, when the reproduction state flag is not 0, the microprocessor 44 determines whether or not the reproduction state flag is 1 (S603). If the reproduction status flag is 1, the microprocessor 44 adds 1 to the value of the standby time counter (S604). Then, the microprocessor 44 (still image data acquisition unit 90) determines whether or not the value of the standby time counter is less than 30 (S605). The value “30” is the length (number of frames) of the second animation data and the fourth animation data for changing the state of the button image.

  Note that the value of the standby time counter is initialized to 0 when the playback button 72 is instructed (see S410 in FIG. 17). In this case, the reproduction state flag is updated to 1, and the second animation data of the reproduction button 72 and the fourth animation data of the stop button 74 are reproduced in order to change the states of the reproduction button 72 and the stop button 74. (See S409 and S410 in FIG. 17). In this case, in S605, it is determined whether or not the reproduction of the second animation data of the reproduction button 72 and the fourth animation data of the stop button 74 is completed. That is, it is determined whether or not the state change of the play button 72 and the stop button 74 is completed.

  Also, the value of the standby time counter is initialized to 0 even when the chapter button is instructed during video reproduction (see S620 in FIG. 20). Also, in this case, the playback state flag is updated to 1, and in order to change the state of the chapter button and the chapter button of the chapter being played when the chapter button is instructed, The second animation data or the fourth animation data of the chapter button is reproduced (see S620 and S622 in FIG. 20, and S303 in FIG. 16). In this case, in S605, it is determined whether or not the reproduction of the second animation data or the fourth animation data of those chapter buttons has been completed. That is, it is determined whether or not the state change of those chapter buttons is completed.

  Further, the value of the standby time counter is initialized to 0 even when the reproduction of any of the first chapter, the second chapter, or the third chapter is completed while the video is being reproduced in the continuous reproduction mode ( (See S627 in FIG. 21). Further, in this case, the reproduction state flag is updated to 1, and the second animation data or the fourth animation data of those chapter buttons is reproduced in order to change the state of the chapter button of the chapter and the next chapter. (See S625 and S627 in FIG. 21). In this case, in S605, it is determined whether or not the reproduction of the second animation data or the fourth animation data of those chapter buttons has been completed. That is, it is determined whether or not the state change of those chapter buttons is completed.

  When the value of the standby time counter is less than 30, that is, when the state of the button image is changing, the microprocessor 44 (first operation screen display control unit 86, switching unit 96) continues to display the dynamic operation screen. (S606).

  On the other hand, when the value of the waiting time counter is not less than 30, that is, when the state change of the button image is completed, the microprocessor 44 and the image processing unit 48 (still image data acquisition unit 90) at that time, the first liquid crystal display unit By capturing the operation screen displayed on 22a, still image data of the operation screen is acquired (S607). More specifically, since the operation screen displayed on the first liquid crystal display unit 22a is stored in a predetermined area on the VRAM, the microprocessor 44 and the image processing unit 48 operate the operation screen stored in the predetermined area. Is copied to another area (still image data storage unit 85b) on the VRAM.

  Thereafter, the microprocessor 44 updates the reproduction state flag to 2 (S608). Further, the microprocessor 44 (second operation screen display control unit 92, switching unit 96) starts displaying the static operation screen. (S609). That is, the operation screen captured in S607 is displayed on the first liquid crystal display unit 22a, and the operation screen displayed on the first liquid crystal display unit 22a is switched from the dynamic operation screen to the static operation screen. Further, the microprocessor 44 (video reproduction control unit 82) reads the video data stored in the memory card 40 (video data storage unit 80) and displays the video on the second liquid crystal display unit 32 (video display unit 84). Start (S610).

  If it is determined in S603 that the playback state flag is not 1, that is, if the playback state flag is 2, the microprocessor 44 (second determination means) displays a button image other than the playback button 72 as shown in FIG. It is determined whether or not an instruction has been issued (S611). If no button image other than the play button 72 is instructed, the microprocessor 44 reads the current chapter number (n) (S612). Then, the microprocessor 44 (third determination unit) determines whether or not the reproduction of the nth chapter is completed (S613). If the reproduction of the n-th chapter has not been completed, the microprocessor 44 (second operation screen display control unit 92, switching unit 96) continues to display the static operation screen (S614). Further, the microprocessor 44 continues to reproduce the video (S615).

  If it is determined in S611 that a button image other than the playback button 72 has been instructed, the microprocessor 44 determines whether the button image is the continuous playback button 60, the chapter playback button 62, or the stop button 74 (S616). ). When the button image is the continuous playback button 60, the chapter playback button 62, or the stop button 74, a process for stopping the playback of the video is executed.

  First, the microprocessor 44 updates the reproduction state flag to 0 (S617). Thereafter, the microprocessor 44 stops the reproduction of the video (S618). Further, the microprocessor 44 (first operation screen display control unit 86, second switching means) starts displaying the dynamic operation screen (S619). That is, the operation screen displayed on the first liquid crystal display unit 22a is switched from the static operation screen to the dynamic operation screen.

  At this time, in order to reflect the operation performed during the display of the static operation screen on the dynamic operation screen, the dynamic operation screen is updated based on the operation performed during the display of the static operation screen. In other words, the microprocessor 44 (first operation screen display control unit 86) corresponds to the button image that the user specified while displaying the static operation screen (in other words, the button image determined to be specified by the user in S611). The processing to be executed is executed at the same time as the display of the dynamic operation screen starts. For example, when the button image designated by the user during the display of the static operation screen is the continuous playback button 60, the continuous playback button process (see FIG. 15) is executed. For example, when the button image designated by the user during the display of the static operation screen is the chapter playback button 62, the chapter playback button process (see FIG. 16) is executed. For example, when the button image instructed by the user during the display of the static operation screen is the stop button 74, stop button processing (see FIG. 18) is executed.

  If it is determined in S616 that the instructed button image is not the continuous playback button 60, the chapter playback button 62 or the stop button 74, that is, if the instructed button image is a chapter button, the state of the instructed chapter button A process for changing to a selected state is executed.

  First, the microprocessor 44 updates the reproduction state flag to 1, and updates the value of the standby time counter to 0 (S620). Thereafter, the microprocessor 44 waits (temporarily stops) playback of the video (S621). In addition, the microprocessor 44 (first operation screen display control unit 86, second switching means) starts displaying the dynamic operation screen (S622). That is, the operation screen displayed on the first liquid crystal display unit 22a is switched from the static operation screen to the dynamic operation screen.

  At this time, the dynamic operation screen is updated to reflect the operation performed during the display of the static operation screen on the dynamic operation screen. That is, the microprocessor 44 (first operation screen display control unit 86) executes the chapter button instruction process (see FIG. 16) simultaneously with the start of the dynamic operation screen display. As a result, the reproduction of the second animation data of the chapter button designated by the user and the fourth animation data of the chapter button of the chapter that was being reproduced when the chapter button was designated is started. As a result, the state of those chapter buttons is updated. Incidentally, in S620, the reproduction state flag is updated to 1, and the standby time counter is updated to 0. For this reason, when the reproduction of the second animation data or the fourth animation data of the above chapter button is started, whether or not the reproduction of the animation data is completed is monitored by the processes of S604 and S605 in FIG. The That is, it is monitored whether or not the update of the state of the chapter button is completed. When the reproduction of the animation data is completed, operation screen capture (re-acquisition of operation screen still image data) is executed (see S607 in FIG. 19). Thereafter, the operation screen is switched from the dynamic operation screen to the static operation screen (see S609 in FIG. 19), and video reproduction is resumed (see S610 in FIG. 19).

  If it is determined in step S613 that the reproduction of the nth chapter has been completed, the microprocessor 44 determines whether or not the reproduction mode flag is 0 as shown in FIG. 21 (S623). If the playback mode flag is 0, it is determined whether or not the current chapter number (n) is 4 (S624). If the current chapter number (n) is not 4, the microprocessor 44 (first operation screen display control unit 86) updates the current playback positions of the nth chapter button and the (n + 1) th chapter button (S625). That is, the current playback position of the nth chapter button is updated to the 91st frame in order to start playback of the fourth animation data that changes the state of the nth chapter button to the non-selected state. Further, the current playback position of the (n + 1) th chapter button is updated to the 31st frame in order to start playback of the second animation data that changes the state of the (n + 1) th chapter button to the selected state. Further, the microprocessor 44 updates the current chapter number to n + 1, and updates the current playback position of the video to the first frame of the (n + 1) th chapter. (S626). Further, the microprocessor 44 updates the reproduction state flag to 1, and initializes the standby time counter to 0 (S627). Thereafter, the microprocessor 44 waits (temporarily stops) reproduction of the video (S628). Further, the microprocessor 44 (first operation screen display control unit 86, third switching means) starts displaying the dynamic operation screen (S629). That is, the operation screen displayed on the first liquid crystal display unit 22a is switched from the static operation screen to the dynamic operation screen.

  Since the current playback positions of the n-th chapter button and the (n + 1) -th chapter button are updated in S625, the fourth animation data of the n-th chapter button and the second animation of the (n + 1) -th chapter button are displayed on the dynamic operation screen at this time. Playback of data is started. As a result, the states of the nth chapter button and the (n + 1) th chapter button are updated. By the way, in S627, the reproduction state flag is updated to 1, and the standby time counter is updated to 0. Therefore, when the reproduction of the fourth animation data of the n-th chapter button and the second animation data of the (n + 1) -th chapter button is started, the animation data is reproduced by the processing of S604 and S605 in FIG. It is monitored for completion. That is, it is monitored whether or not the update of the states of the nth chapter button and the (n + 1) th chapter button is completed. When the reproduction of the animation data is completed, operation screen capture (re-acquisition of operation screen still image data) is executed (see S607 in FIG. 19). Thereafter, the operation screen is switched from the dynamic operation screen to the static operation screen (see S609 in FIG. 19), and video reproduction is resumed (see S610 in FIG. 19).

  When it is determined in S623 that the playback mode flag is not 0, the playback of the nth chapter is completed in the chapter playback mode. Further, when it is determined in S624 that the current chapter number (n) is 4, this is a case where the playback of the fourth chapter is completed in the continuous playback mode. In these cases, processing for stopping the reproduction of the video is executed.

  That is, the microprocessor 44 (first operation screen display control unit 86) updates the current playback position of the nth chapter button to the 91st frame in order to change the state of the nth chapter button to a non-selected state (S630). . Further, the microprocessor 44 updates the current chapter number to 0 (S631). Further, the microprocessor 44 (first operation screen display control unit 86) updates the current reproduction positions of the reproduction button 72 and the stop button 74 (S632). That is, in order to change the state of the playback button 72 to the non-selected state, the current playback position of the playback button 72 is updated to the 91st frame. In order to change the state of the stop button 74 to the selected state, the current playback position of the stop button 74 is updated to the 31st frame. Further, the microprocessor 44 updates the reproduction state flag to 0 (S633). Thereafter, the microprocessor 44 and the image processing unit 48 stop the reproduction of the video (S634). Further, the microprocessor 44 (first operation screen display control unit 86, third switching means) starts displaying the dynamic operation screen (S635). That is, the operation screen displayed on the first liquid crystal display unit 22a is switched from the static operation screen to the dynamic operation screen.

  Since the current playback positions of the nth chapter button, the playback button 72, and the stop button 74 are updated in S630 and S632, the fourth animation data of the nth chapter button and the playback button 72 is displayed on the dynamic operation screen at this time. The reproduction of the second animation data of the stop button 74 is started. As a result, the states of the nth chapter button, the playback button 72, and the stop button 74 are updated.

  In the video reproduction apparatus 10 described above, an operation screen (dynamic operation screen) is displayed based on moving image data in principle. As a result, a dynamic operation screen that changes according to the user's operation is realized, and the interest of the operation relating to the reproduction of the video is improved.

  By the way, since the dynamic operation screen is displayed by reproducing the animation data of each button image, the processing load for displaying the operation screen becomes heavy. For this reason, there is a possibility that the processing for reproducing the video cannot be performed sufficiently. As a result, the reproduction quality of the video may be degraded. In this regard, in the video playback device 10, the operation screen displayed on the first liquid crystal display unit 22a is switched between the dynamic operation screen and the static operation screen based on the execution state of the video playback processing. More specifically, the dynamic operation screen is displayed when the video playback process is not executed (when the video is not played back). When execution of the video playback process is started (when video playback is started), the operation screen displayed on the first liquid crystal display unit 22a is switched from the dynamic operation screen to the static operation screen. . As a result, the static operation screen is displayed while the video playback process is being executed (during video playback), and the processing load for displaying the operation screen is reduced. According to the video playback device 10, it is possible to suppress a reduction in video playback quality due to a processing load for displaying an operation screen.

  Further, the video playback device 10 generates still image data of the operation screen by capturing the operation screen displayed on the first liquid crystal display unit 22a at a predetermined timing while the dynamic operation screen is displayed. The As a result, a static operation screen that reflects the user's operation content is displayed. As a method for displaying a static operation screen that reflects the user's operation content, multiple types of still image data are prepared in advance in consideration of the operation content that can be performed on the operation screen. It is also possible to keep it. For example, a method of preparing still image data representing the operation screens of FIGS. 4 to 7 in advance may be considered. However, in this case, the amount of data increases. In this regard, according to the video display device 10, it is not necessary to prepare a plurality of types of still image data on the operation screen, so that the data amount can be reduced.

  Further, in the video reproduction apparatus 10, when the user performs an operation while the static operation screen is displayed, the operation screen displayed on the first liquid crystal display unit 22a is switched from the static operation screen to the dynamic operation screen (see FIG. 20 S611, S619, and S622). Then, the animation data of each button image is reproduced according to the content of the operation performed by the user while the static operation screen is displayed (S619 and S622 in FIG. 20, S202, S205 and S208 in FIG. 15, and S303 in FIG. 16). , See S503 and S505 in FIG. In this manner, in the video reproduction device 10, the operation contents performed by the user while the static operation screen is displayed are reflected on the operation screen.

  For example, it is assumed that the user instructs the first chapter button 64 while the static operation screen is being displayed and the third chapter is being played. In this case, the operation screen displayed on the first liquid crystal display unit 22a is switched from the static operation screen to the dynamic operation screen (see S611 and S622 in FIG. 20). The second animation data (first operation member moving image data) of the first chapter button 64 (first operation member image) and the fourth animation data (second operation) of the third chapter button 68 (second operation member image). Operation member moving image data) is reproduced (see S622 in FIG. 20 and S303 in FIG. 16). As a result, the states of the first chapter button 64 and the third chapter button 68 are updated. Then, after the reproduction of the animation data is completed, the operation screen displayed on the first liquid crystal display unit 22a is captured to re-acquire still image data of the operation screen (S605 and S607 in FIG. 19). reference). Further, thereafter, the operation screen displayed on the first liquid crystal display unit 22a is switched from the dynamic operation screen to the static operation screen (see S609 in FIG. 19). In this way, in the video reproduction apparatus 10, the operation content performed by the user while the static operation screen is displayed is reflected on the static operation screen.

  By the way, in this case, the re-acquisition of the still image data of the operation screen (capture of the operation screen) needs to be executed after the reproduction of the second animation data or the fourth animation data such as the chapter button designated by the user is completed. There is. In this regard, in the video display device 10, since the length (number of frames) of the second animation data and the fourth animation data of each button image is unified to 30 frames, the timing of re-acquisition of still image data of the operation screen Can be determined relatively easily (see S605 in FIG. 19).

  Further, in the video playback device 10, when the progress of video playback changes while the static operation screen is displayed (that is, when playback of the first chapter, the second chapter, the third chapter, or the fourth chapter is completed). The operation screen displayed on the first liquid crystal display unit 22a is switched from the static operation screen to the dynamic operation screen (see S613 in FIG. 20 and S629 and S635 in FIG. 21). Then, the animation data of the button image is reproduced in accordance with the change in the progress of the video reproduction (see S625, S630, and S632 in FIG. 21). In this way, in the video playback device 10, when the progress of video playback changes while the static operation screen is displayed, the content of the change is reflected on the operation screen.

  For example, it is assumed that the reproduction of the first chapter is completed and the reproduction of the second chapter is started while the static operation screen is displayed. In this case, the operation screen displayed on the first liquid crystal display unit 22a is switched from the static operation screen to the dynamic operation screen (see S629 in FIG. 21). The fourth animation data (first progress video data) of the first chapter button 64 (first progress image) and the fourth animation data (second progress) of the third chapter button 68 (second progress image). Progression level moving image data) is reproduced (see S625 in FIG. 21). As a result, the states of the first chapter button 64 and the third chapter button 68 are updated. Then, after the reproduction of the animation data is completed, the operation screen displayed on the first liquid crystal display unit 22a is captured to re-acquire still image data of the operation screen (S605 and S607 in FIG. 19). reference). Further, thereafter, the operation screen displayed on the first liquid crystal display unit 22a is switched from the dynamic operation screen to the static operation screen (see S609 in FIG. 19). In this way, in the video playback device 10, when the playback of the first chapter, the second chapter, or the third chapter is completed while the static operation screen is displayed, and playback of the next chapter is started, Is reflected in the static operation screen.

  In this case, re-acquisition of the still image data of the operation screen (capture of the operation screen) needs to be executed after all the reproduction of the second animation data or the fourth animation data of the chapter button is completed. In this regard, in the video display device 10, since the length (number of frames) of the second animation data and the fourth animation data of the chapter button is unified, it is relatively easy to re-acquire the still image data of the operation screen. Can be judged.

  The present invention is not limited to the embodiment described above.

  For example, the still image data storage unit 85b may store a plurality of still image data of the operation screen. In this case, the plurality of still image data stored in the still image data storage unit 85b includes, for example, still image data of the operation screens illustrated in FIGS. In this case, the still image data storage unit 85b stores conditions relating to the operation contents in association with each of the plurality of still image data. The “condition regarding the operation content” is, for example, a condition regarding a combination of currently selected buttons. The second operation screen display control unit 92 determines the content of the operation performed by the user based on the video reproduction control data. For example, the second operation screen display control unit 92 determines the combination of currently selected buttons. Then, the second operation screen display control unit 92 reads out still image data corresponding to the above-described condition that satisfies the operation performed by the user from the still image data storage unit 85b, and displays the still image data on the moving image display unit 88. . Even in this case, it is possible to suppress a reduction in the reproduction quality of the video due to the processing load for displaying the operation screen. In addition, a static operation screen that reflects the content of the operation performed by the user is displayed.

  Further, for example, the cross button 24c and the button 24a may be used for the operation on the operation screen. For example, a cursor that moves according to the operation of the cross button 24c may be displayed on the operation screen. Then, when the button 24a is selected in a state where the cursor is positioned on any button image, it may be determined that the button image is instructed.

  For example, the operation screen may include an operation member image other than the button image. For example, a slider bar image for adjusting the volume may be included in the operation screen.

  For example, the video display unit 84 may display a game screen (game play video). For example, the video display unit 84 may display a video representing a state in which a game space in which various objects are arranged is viewed from a virtual camera according to an operation on the operation screen. In this case, the video data storage unit 80 stores data indicating the state of the game space. The “data indicating the state of the game space” is data indicating, for example, various objects arranged in the game space, the current position and posture of the virtual camera, and the like. Then, the video reproduction control unit 82 generates an image representing a state in which the game space is viewed from the virtual camera based on the above data every predetermined time (for example, 1/60 seconds), and the image is displayed on the video display unit 84. indicate.

  In the above description, the program is supplied from the memory card 40 as an information storage medium to the video display device 10 (portable game machine 12). However, the program is distributed to a home or the like via a communication network. Also good. FIG. 22 is a diagram showing an overall configuration of a program distribution system using a communication network. A program distribution method according to the present invention will be described with reference to FIG. As shown in FIG. 22, the program distribution system 100 includes a program distribution device 108, a communication network 106, and a portable game machine 12. The program distribution device 108 includes a database 102 and a server 104. The communication network 106 includes, for example, the Internet and a cable television network. In this system, a program similar to the storage content of the memory card 40 is stored in the database (information storage medium) 102. Then, when the consumer makes a program distribution request using the portable game machine 12, it is transmitted to the server 104 via the communication network 106. Then, the server 104 reads the program from the database 102 in response to the program distribution request and transmits it to the portable game machine 12. Here, the program is transmitted in response to the program distribution request, but the program may be transmitted unilaterally from the server 104. Thus, if the program is distributed via the communication network 106, the consumer can easily obtain the program.

  Note that the operation screen display unit 88 and the video display unit 84 may be realized by a single display unit (display, television, or the like). That is, the operation screen (operation panel image) and the video playback screen may be displayed on one display means (display, television, etc.).

  In addition, the video reproduction device 10 can be realized using a computer other than the portable game machine 12. For example, the video playback device 10 can be realized using an optical disk playback device such as a DVD (registered trademark) player. Further, for example, the video reproduction device 10 can be realized by using a personal computer, a mobile phone, a personal digital assistant (PDA), a stationary game device, or the like. In the case where the video playback device 10 is realized using an optical disc playback device, a personal computer, or a stationary game device, for example, a monitor, a liquid crystal display, a television, or the like is used as the display means.
