Description

  The present invention relates to a navigation album system capable of creating an electronic album in which digital image data is linked to position information of a movement path, and more particularly to a technique for reproducing moving image data as digital image data.

  In recent years, higher performance and lower prices of car navigation systems are progressing, and the number of vehicles equipped with car navigation systems is increasing. For example, as described in Patent Document 1, the car navigation system displays a route to be traveled by setting a destination on the display, or stores a route traveled by a private vehicle, and the route Can be displayed on the display.

  In Patent Literature 1, image data, voice data, and the like as additional information are recorded in association with the guidance route data to the destination and the actually traveled locus data, and the guidance route data and the locus data are stored in the display device. When displaying, the image data and music data associated with each other are output. This navigation device displays the current position detected by the position detector on the map by map matching processing, and when a destination or waypoint is input, performs a route search operation to display the guidance route data on the map. When this guide route is registered, additional information such as arbitrary image data related to the guide route is stored in association with the guide route according to the user's operation, and the stored additional information is selected in this way. It can be called and displayed automatically.

  On the other hand, in recent years, digital cameras have improved in performance and price, and when traveling to sightseeing spots etc. by vehicle, take digital cameras with them to take pictures of sights and historic sites. Taking snapshots is increasing. In addition, there are many opportunities to shoot movies in sightseeing spots using digital cameras and digital video cameras that can shoot movies.

  Then, the photograph and the video taken in this way are stored in a recording medium such as a CD-R or DVD-R, an electronic album is created, and the photo or the video is displayed on a computer, a TV monitor or the like for enjoyment. ing.

  Normally, electronic albums are generally those in which digital image data is simply displayed as thumbnails or displayed on the screen in a slide show format, and when images taken when traveling around multiple sightseeing spots are reviewed at a later date, When it comes to recalling memories at the time of travel, it was difficult to immediately determine when and where the images were taken.

  Therefore, the present inventor has proposed a navigation album in which the car navigation system and the electronic album are fused so that the user can easily recall memories at the time of travel.

  Specifically, when the electronic album is opened, the navigation album displays the travel route data that the user has traveled on the vehicle on the day of travel as it is on the screen, and shows the current location on the screen as in normal car navigation ( When the vehicle symbol) moves along the travel route at the time of travel and arrives at a sightseeing point visited by the user, digital image data taken at that location is displayed as a thumbnail or a slide show.

As a result, the travel mood can be reproduced by tracing the route traveled by the private car at the time of travel on the screen as it is, and the current location cursor is displayed on the navigation album screen. Since it is displayed for the first time when moving to the ground, it is possible to relive the schedule from the departure date to the last date of the trip faithfully in the order of travel, and to easily reproduce the mood of the trip .

  However, when a navigation album in which digital image data in which photos and moving images are mixed is recorded is reproduced in a slide show format, in the case of photos, the display is switched one after another at a predetermined interval (for example, about 5 to 10 seconds). However, in the case of a moving image, it will continue to be played endlessly until the playback time ends, and will not switch to the next data. As described above, if there is a difference in the reproduction time between the photograph and the moving image, the rhythm of the display interval of the slide show display is deteriorated, and the album viewer may be bored.

  Also, in general, when a user shoots a video with a digital video camera or the like, there is a tendency to shoot unnecessary scenes endlessly. Often part. In other words, it is more interesting and focused for the album viewer to record the edited video by extracting only the part that the user thinks necessary rather than playing the recorded video in an unedited state. It can be appreciated.

  However, if the user must edit the recorded video each time and then record it in the navigation album, the task is very cumbersome and time-consuming, which makes it difficult to create the navigation album itself. is there.

[Specification of route data R]
Next, a procedure for specifying route data that has traveled during the travel period in the navigation album system according to the first embodiment of the present invention will be described. As shown in FIG. 3, in step S101, image data mixed with photographs and moving images stored in a storage medium such as the semiconductor medium Ms or the disk-shaped medium Md is transferred to the semiconductor drive 8, the disk drive 9, or the input / output. Input to the hard disk HD via the terminal 5.

  In the first embodiment, the image data is read only from the storage medium used by the user for shooting. However, the present invention is not limited to this. For example, other members who traveled together may shoot each image. Alternatively, the image data may be read from the storage medium used for the recording and additionally input to the hard disk HD. Of course, the image data may be input to the hard disk HD only from the storage media of other members. The same applies to the following Embodiment 2 or 3.

  Next, in step S102, image data that the user determines is not necessary to be placed on the album is selected and deleted from the plurality of image data input to the hard disk HD.

  In step S103, it is determined whether Exif information including shooting date / time information is added to the input digital image data. If “YES” at step S103, the process branches to step S104.

  In step S104, the date information reading means 18 reads information indicating the shooting date and time from the Exif information, specifies the shooting date and time of the image data, and proceeds to step S105. In step S105, the determination means 19 determines the travel period by determining the oldest day as the departure date and the newest date as the final date among the shooting dates and times of the plurality of image data read by the date information reading means 18. .

  In step S106, the route display means 20 reads the route data R traveled by the vehicle within the travel period specified by the determination means 19 from the hard disk HD and displays it on the display C, thereby creating a navigation album. The specification of the route data R for is completed.

  On the other hand, if the determination in step S103 is “NO”, the process branches to step S107, and a date input screen prompting the user to input the date of the travel period is displayed on display C in step S107. In step S108, the process waits until the date input is completed. When the date input is completed, the process branches to step S105.

  As described above, when the Exif information including the shooting date / time information is added to the digital image data, the user can input and specify the date of the travel period simply by inputting the digital image data into the navigation album system. Even if it is not, it is possible to automatically specify the route data R that has traveled within the travel period. For this reason, the burden on the user in creating the navigation album is reduced.

  Further, even when Exif information including the shooting date and time is not added to the digital image data, a date input screen prompting the user to input a date for the travel period is displayed on the display C, which is advantageous in preventing omission of date input. It is.

[Association between image data and sightseeing spot]
In the case of associating digital image data in which snapshots and moving images taken with the digital camera Cam are mixed with the sightseeing spot information in which the image data was taken during the trip, it is shown in FIG. The processing menu 28 is displayed on the display C and the “image data acquisition” button 21 is operated. In this processing menu 28, in addition to the “obtain image data” button 21, a “playback processing (actual running mode)” button 22, a “playback processing (replay mode)” button 23, and “save to media”. A button 24 and an “OK” button 25 are displayed.

  When the “acquire image data” button 21 is operated and the “OK” button 25 is operated, first, the association process shown in the flowchart of FIG. 6 is executed.

  In the association process, in step S201, one of a plurality of image data acquired via the semiconductor drive 8 or the like is displayed on the image acquisition screen 27 shown in FIG. In step S202, candidates for the titles of sightseeing spot information ("USJ" and "Kaiyukan" in FIG. 5) recorded on the hard disk HD are displayed in a list below the image acquisition screen 27.

  The sightseeing spot title specifies the shooting date and time from the Exif information added to the image data displayed on the image acquisition screen 27, and the location information of the vehicle stopped at this shooting date and time is stored in the route storage processing means 14. By reading out from the stored route data R, candidates for the nearest sightseeing spot title at the position are displayed as a list. Then, by operating the scroll cursor 26, all the tourist destination title candidates can be confirmed.

  In step S203, it is determined whether the image data displayed on the image acquisition screen 27 needs to be associated with the tourist destination title. If the determination in step S203 is “YES”, the process branches to step S204, and “registration” is performed in the state where the title of the sightseeing spot where the image data displayed on the image acquisition screen 27 is captured is selected in step S204. "Button 29 is operated. As a result, the association between the image data displayed on the image acquisition screen 27 and the sightseeing spot title of the shooting location ends, and the process proceeds to step S205.

  If the determination in step S203 is “NO” (because the photo is not good or there are many photos with similar angles, etc.), the “Cancel” button 30 is operated to display the title of the tourist destination. The process branches to step S205 without associating the image data with.

  In step S205, it is determined whether the next image data exists. If the determination in step S205 is “YES”, the process branches to step S201, and the next image data is displayed on the image acquisition screen 27. . If the determination in step S205 is “NO”, the process of associating the image data with the tourist destination title is terminated.

  Next, the image editing screen 31 shown in FIG. On the image editing screen 31, the image data associated with the tourist destination title is displayed one by one. A title bar 32 is displayed at the lower position of the image editing screen 31, and a sightseeing spot title (“USJ” in FIG. 7) associated with the image data is displayed at the left end of the title bar 32. The shooting date and time acquired from the Exif information of the image data is displayed at the right center position.

  At the right end of the title bar 32, an image associated with a sightseeing spot registered in advance for each sightseeing spot is inserted and combined, and a plurality of images are selected according to the user's preference. And can be switched.

  In addition, a sub image display screen 33 is displayed at the upper right of the screen, and the location information of the sightseeing spot is displayed as map data. The sub-image display screen 33 is displayed so as to overlap the displayed image data, and can be set to non-display when the image data is difficult to see.

[Procedure for setting the playback time and playback range of moving image data]
Here, when the image data includes moving image data, it is necessary to set a reproduction time and a reproduction range for the moving image data. Hereinafter, the procedure for setting the playback time and playback range of moving image data will be described with reference to the flowchart shown in FIG.

  First, a moving image editing screen (not shown) is displayed on the display C, and as shown in FIG. 8, the reproduction time T of the entire moving image data is calculated in step S301. As shown in FIG. 9, in the first embodiment, it is assumed that the reproduction time T is 60 sec.

  In step S302, the playback time setting means 70 sets the playback time t of the moving image data. As this setting method, for example, when the photo display interval when the navigation album is played in the slide show format is set to 10 sec, the playback time t of the moving image data is also set to 10 sec. It is conceivable to directly input the playback time t using a keyboard, a touch panel, or the like. In the following description, it is assumed that the playback time t is set to 10 sec.

  Next, in step S303, it is determined whether the reproduction time T of the entire moving image data is longer than the reproduction time t set by the reproduction time setting means 70, that is, whether T ≧ t is satisfied.

  If the determination in step S303 is “NO”, the process branches to step S308, and the reproduction time t is reset to the reproduction time T of the entire moving image data in step S308. In step S309, the reproduction range setting unit 71 sets the reproduction range for the entire moving image data, and the setting of the reproduction range ends.

  If “YES” at step S303, the process branches to step S304, and the central position of the moving image data is detected based on the reproduction time T of the entire moving image data at step S304. Specifically, as shown in FIG. 9, since the reproduction time T of the entire moving image data is 60 seconds, data at half the time point (30 seconds) is detected.

  In step S305, the reproduction range setting means 71 sets a predetermined range including the detected moving image central portion as a reproduction range. Specifically, since the set playback time t is 10 sec, it is preferable to set a range including 5 sec before and after the central portion of the moving image as the playback range.

  It should be noted that the reason why the predetermined range including the central portion of the moving image is set as the playback range is most likely that this portion is a highlight scene in the moving image data, and when other users watch the album, they are bored. This is because there are few things.

  Next, in step S306, the set playback range is previewed on the display C to determine whether the playback range is as desired by the user. If the determination in step S306 is “YES”, the setting of the reproduction range ends.

  If “NO” at step S306, the process branches to step S307, where the user designates a reproduction range in an arbitrary range and corrects it by the reproduction range correction means 72. Here, the reproduction range is designated by an external input means such as a touch panel or a remote controller.

  Such setting of the reproduction range is performed by adding a chapter to the moving image data, and does not trim and delete moving image data outside the set reproduction range. In this way, since the original moving image data remains without any change, the entire moving image data is set as the reproduction range or reset to another reproduction range as necessary. Be able to. The same applies to the following Embodiment 2 or 3.

  As described above, by setting the playback time of moving image data, when playing a navigation album in which photos and videos are mixed in a slide show format, the display time of the photos and the playback time of the videos are combined. Can be switched with good rhythm. In addition, since a predetermined range including the central part of the moving image that is presumed to be a highlight scene in the moving image data can be automatically set as the reproduction range, the user does not have to check the entire moving image data. Work efficiency of album creation is improved.

[Other association procedures]
In the next process, the BGM set screen 40 shown in FIG. 10 is displayed on the display C. When the user needs it, the “YES” button 41 is operated. When the “NO” button 42 is operated and the “YES” button 41 is operated, the song names stored in the music database are displayed in a list on the song name display unit 43, and when auditioning, the “trial listening” button 44 is displayed. The music data can be auditioned by the speaker 2 by operating the “OK” button 45 when the music selection is completed, and the music data is set as one BGM for the route data R. The process proceeds to the next process. When music data is set in this way, different music data may be set for each tourist destination title. Further, for example, more detailed music data may be set, such as setting the BGM used in the movie “Jaws” to flow for the image data shot at the Joe's attraction in USJ.

  In the next process, a title input screen (not shown) is displayed on the display C. In the title input work, the tourist destination title selected previously is input as it is, so that the user does not have to work. When the user wants to correct to an arbitrary title, he / she can input necessary characters using the keyboard displayed on the title input screen.

[Launch Navigation Album]
As described above, after all the association between the image data and the sightseeing spot information is completed, the “save to media” button 24 is operated from the processing menu 28 to save the image data to the disk-like medium Md. The process to perform is performed, and a navigation album is created.

  When the navigation album is set in a general household computer or the like, a title menu screen 50 shown in FIG. 11 is displayed. On the title menu screen 50, a title display section 50A indicating the title of the album and a date display section 50B indicating the date of travel are displayed so that it is possible to determine when and where the electronic album is traveled. . Further, three menus of a navigation slide 51, a map slide 52, and a slide show 53 are displayed. As will be described later, the three menus have different image display methods.

  When the navigation slide menu 51 is selected, the screen is switched to a map display screen 60 as shown in FIG. On this map display screen 60, a timeline bar 61 and a plurality of playback control buttons 62 are displayed. By operating a playback button of the playback control buttons 62 or operating the timeline bar 61, A state in which the vehicle symbol V moves on the route data R is displayed with a reduced time (in a simulated state).

  Then, when the vehicle symbol V departs from the departure position St and travels on the route data R and arrives at the first sightseeing spot P1, the image data registered in association with the sightseeing spot P1 is as shown in FIG. Are displayed in a preset order and at preset intervals. Here, when the image data is a moving image, the reproduction range set by the reproduction range setting means 71 is reproduced and displayed, and when the set reproduction time elapses, the next image data is switched.

  After all the image data registered in the sightseeing spot P1 has been viewed, the display is switched again to the map display screen 60, and the vehicle symbol V travels toward the next sightseeing spot P2. As described above, the image data registered in each of the sightseeing spots P1 to P3 in chronological order until the vehicle symbol V travels through all the sightseeing spots P1 to P3 and arrives at the arrival position G. I can enjoy it.

  If there is a famous sightseeing spot in the route data R, if the sightseeing spot information is registered in the hard disk HD, the sightseeing spot information is displayed when the vehicle symbol V travels around the famous sightseeing spot. You may make it display.

  When the Map slide menu 52 is selected, the map display screen 60 is displayed as in the case of the navigation slide menu 51.

[Other image data display methods]
The navigation album system according to the first embodiment is mainly intended to create a navigation album on a disc-shaped medium Md or the like and view it on a computer at home, etc. You can enjoy the data.

  In other words, as shown in FIG. 4, when the processing menu 28 is displayed on the display C and the “reproduction processing (actual driving mode)” button 22 of the processing menu 28 is operated, a list of tourist destination titles is selected. A screen (not shown) is displayed. By selecting the album title to be played and operating the “OK” button, the route data R corresponding to the title is designated, and the actual driving mode screen is displayed on the display C. Is done.

  Then, as shown in FIG. 12, when the vehicle symbol V approaches the tourist spot P1 on the route data R as the vehicle travels, a new window is opened in a state of overlapping a part of the map data, and the tourist spot P1 is opened. A plurality of associated image data is displayed in a preset order at a set interval, and when music data is associated, the music data is reproduced.

  Further, when the “playback processing (replay mode)” button 23 of the processing menu 28 displayed on the display C is operated, a selection screen is displayed in the same manner as described above, and an album title to be played back is selected and “OK” is displayed. ”Button is designated, the route data R corresponding to the title is designated, and the replay mode screen is displayed on the display C.

  This replay mode screen is the same as the map display screen 60 in FIG. 12, and the operation of the navigation album can be simulated on the display C. Therefore, before the navigation album data is stored in the disc-shaped medium Md. It is effective as a preview screen.

  As described above, when the actual driving mode is selected, when the vehicle approaches the sightseeing spot P1 set on the route data R, the image data associated with the sightseeing spot P1 is displayed on the display C. Therefore, the passenger can view the image data taken at the sightseeing spot P1 visited in the past. In this case, the vehicle does not need to travel on the route data R, and a plurality of image data is automatically displayed every time the vehicle approaches the sightseeing spot P1.

  When the replay mode is selected, the route data R is displayed on the map data displayed on the display C even when the vehicle is stopped, and the vehicle symbol V is moved and displayed on the route data R. When the vehicle symbol V approaches the sightseeing spot P1, a plurality of image data set in the sightseeing spot P1 is automatically displayed, so that, for example, image data taken during a trip can be displayed for each sightseeing spot. Yes.

  In the first embodiment, a signal from a GPS satellite is used as the position acquisition unit. However, this position acquisition unit is similar to the position acquisition method realized by, for example, a PHS mobile phone. Alternatively, by receiving radio waves from a plurality of radio wave transmission sources installed on the ground, the position of the vehicle may be acquired based on these transmission sources. The same applies to the following second and third embodiments.

  Further, in the first embodiment, the form of creating a navigation album on the car navigation display screen has been described. However, the present invention is not limited to this form. For example, the position information of the specified travel route is displayed as car navigation. The navigation album may be created using a program installed in a personal computer at home. The same applies to the following second and third embodiments.

<Embodiment 2>
FIG. 13 is a block diagram showing a configuration of a navigation album system according to Embodiment 2 of the present invention. In the second embodiment, a volume discriminating means 73 is added to the first embodiment. Here, the volume discrimination means 73 discriminates the volume of the audio data added to the moving image data.

  Next, a procedure for setting the playback time and playback range of moving image data in the navigation album system according to the second embodiment will be described with reference to the flowchart shown in FIG.

  First, a moving image editing screen (not shown) is displayed on the display C, and the reproduction time T of the entire moving image data is calculated in step S401. As shown in FIG. 15, in the second embodiment, it is assumed that the reproduction time T is 60 sec.

  In step S402, the reproduction time setting means 70 sets the reproduction time t of the moving image data. As this setting method, for example, when the photo display interval when the navigation album is played in the slide show format is set to 10 sec, the playback time t of the moving image data is also set to 10 sec. May directly input the reproduction time t using a touch panel, a remote controller, or the like. In the following description, it is assumed that the playback time t is set to 10 sec.

  Next, in step S403, it is determined whether the playback time T of the moving image data is longer than the playback time t set by the playback time setting means 70, that is, whether T ≧ t is satisfied.

  If “NO” in step S403, the process branches to step S408, and the reproduction time t is reset to the reproduction time T of the entire moving image data in step S408. In step S409, the reproduction range setting unit 71 sets the reproduction range for the entire moving image data, and the setting of the reproduction range ends.

  If the determination in step S403 is “YES”, the process branches to step S404, and in step S404, a waveform indicating the volume of the audio data added to the moving image data by the volume determination unit 73 is displayed over the entire moving image data. Based on the determination result, data at the time when the volume of the audio data is maximum is detected in the moving image data. Specifically, in the case of the audio data shown in FIG. 15, the volume at the position where 40 seconds have elapsed from the start of the reproduction of the moving image data is maximum, so the data at that time is detected.

  In step S405, the reproduction range setting means 71 sets a predetermined range including the detected maximum volume as a reproduction range. Specifically, since the set playback time t is 10 sec, it is preferable to set a range including 5 sec before and after the maximum volume position as the playback range.

  The predetermined range including the maximum volume portion is set as the playback range. This playback range is a scene in which some event such as joy or surprise, or a change in the surrounding sound occurs. This is because it is most likely to be a highlight scene in the middle, and it is considered that other users are less bored when viewing the album.

  In step S406, the set playback range is previewed on the display C to determine whether the playback range is as desired by the user. If the determination in step S406 is “YES”, the setting of the reproduction range ends.

  If the determination in step S406 is “NO”, the process branches to step S407. In step S407, the user designates a reproduction range in an arbitrary range, and the reproduction range correction unit 72 corrects the reproduction range. Here, the reproduction range is designated by an external input means such as a touch panel or a remote controller.

  As described above, a predetermined range including a maximum volume portion that is presumed to be a highlight scene in moving image data can be automatically set as a reproduction range, so the user bothers to check the entire moving image data. There is no need to improve the work efficiency of album creation.

<Embodiment 3>
FIG. 16 is a block diagram showing a configuration of a navigation album system according to Embodiment 3 of the present invention. In the third embodiment, reproduction speed changing means 74 is added to the first embodiment. Here, the reproduction speed changing means 74 changes the reproduction speed of the moving image data to an arbitrary speed and reproduces it.

  Next, a procedure for reproducing moving image data in the navigation album system according to the third embodiment will be described with reference to the flowchart shown in FIG.

First, a moving image editing screen (not shown) is displayed on the display C, and the reproduction time t ₁ of the moving image data is set by the reproduction time setting means 70 in step S501. In the following description, it is assumed that the playback time t is set to 10 sec.

  In step S502, the reproduction range of the moving image data is set by the reproduction range setting means 71. The reproduction range may be set automatically by the method described in the first or second embodiment, or may be directly input by the user using an external input unit such as a touch panel or a remote controller. good.

Next, it is determined whether or not at step S503, whether the reproduction time t ₂ of the playback range of the moving image data is longer than the reproduction time t ₁ set by the reproduction time setting unit 70, namely satisfy t ₂ ≧ t _1.

If the determination in step S503 is “NO”, the process branches to step S504. In step S504, the set reproduction time t ₁ is reset to the reproduction range reproduction time t ₂ and the process ends. At this time, the playback speed of the moving image data is not changed, and playback at the normal playback speed is executed.

If “YES” in step S503, the process branches to step S505. In step S505, the reproduction speed changing unit 74 finishes reproducing the entire reproduction range of the moving image data within the set reproduction time t ₁ . In other words, the playback speed of the playback range is changed so as to satisfy t ₁ = t ₂ . Specifically, for example, when the playback time is set to 10 sec and the playback range of the moving image data is set to 20 sec, by changing the playback speed so that this playback range is played back at double speed, The reproduction of the reproduction range is completed within 10 seconds of the set reproduction time. Similarly, in the case of reproducing the entire moving image data having a total reproduction time of 60 seconds, if the entire moving image data is reproduced at 6 times speed, the reproduction ends within the set reproduction time of 10 seconds.

  As described above, the playback speed changing unit 74 changes the playback speed of the playback range so that the playback of the playback range of the moving image data is completed within the set playback time. Even in such a case, the entire moving image can be viewed without cutting a part of the moving image, and an advantageous effect can be obtained in remembering the scene at the time of travel in more detail.

  Next, another procedure for reproducing moving image data in the navigation album system will be described with reference to the flowchart shown in FIG.

First, a moving image editing screen (not shown) is displayed on the display C, and the reproduction time t ₁ of the moving image data is set by the reproduction time setting means 70 in step S601. In the following description, it is assumed that the playback time t ₁ is set to ₁₀ sec.

  In step S602, the reproduction range setting unit 71 sets the reproduction range of the moving image data. The setting of the reproduction range may be performed by the method described in the first or second embodiment, or may be performed by the user directly inputting with an external input unit such as a touch panel or a remote controller.

Next, it is determined whether or not at step S603, whether the reproduction time t ₂ of the playback range of the moving image data is longer than the reproduction time t ₁ set by the reproduction time setting unit 70, namely satisfy t ₂ ≧ t _1.

If the determination is "NO" in step S603, branches to step S604, the in step S604, the ends reconfigure the reproduction time t ₁ set to the reproduction time t ₂ of the playback range. At this time, the playback speed of the moving image data is not changed, and playback at the normal playback speed is executed.

If the determination in step S603 is “YES”, the process branches to step S605. In step S605, the reproduction range (t ₂ −t ₁ ) after the reproduction time t ₁ has elapsed is determined by the reproduction speed changing unit 74. Change the playback speed to play faster. Specifically, for example, when the playback time is set to 10 sec and the playback range of the moving image data is set to 30 sec, playback is performed at a normal playback speed until the playback time of 10 sec elapses, and 10 sec elapses. The playback speed of the remaining 20 sec playback range that has not been played back later is changed to perform high-speed playback.

  As described above, when the playback of the set playback range does not end within the set playback time, the playback speed of the subsequent playback range that has not been played is changed by the playback speed changing means 74 and the playback speed is changed. Since the image data is reproduced at a high speed, fluctuations in the display switching interval of the image data during album reproduction can be minimized, and an advantageous effect can be obtained in reproducing with good rhythm.

  As described above, the present invention can be used to create an electronic album that realizes smooth display switching of image data in which pictures and videos are mixed, without requiring the user to perform troublesome operations such as editing of moving image data. Therefore, it is extremely useful and has high industrial applicability.
