  In recent years, with the increase in capacity of storage media, it has become possible to store many contents (for example, moving image data) in the storage media. On the other hand, as the number of moving image data that can be stored increases, it becomes more difficult to find desired moving image data from the stored moving image data.

  Therefore, a display device that makes it easy to find the desired moving image data by displaying the thumbnail image of the first frame of the moving image data for each moving image data so that the contents can be confirmed without reproducing each moving image data. Has been proposed. For example, see Patent Document 1.

  When a predetermined button is pressed while an arbitrary thumbnail image is selected, thumbnail images of frames at predetermined time intervals are extracted from the moving image data corresponding to the thumbnail image and displayed side by side. A display device has also been proposed. For example, see Patent Document 2.

  As described above, in this display device, by displaying a plurality of thumbnail images representing the contents of each moving image data, moving image data is more detailed than when only the first frame thumbnail image is displayed. The contents of can be confirmed.

1. 1. First embodiment 2. Second embodiment 3. Third embodiment 4. Fourth embodiment 5. Fifth embodiment 6. Sixth embodiment Other embodiments

<1. First Embodiment>
[1-1. Outline of First Embodiment]
First, the outline of the first embodiment will be described. Incidentally, after describing this outline, the description moves to a specific example of the present embodiment.

  In FIG. 1, reference numeral 1 denotes a display device. The display device 1 includes a storage control unit 3 that stores moving image data in a storage medium 2. The display device 1 also includes a display unit 4 that displays an image representing the content of moving image data stored in the storage medium 2 on a display screen.

  The display device 1 further includes a detection unit 5 that detects a plurality of operation inputs on the display screen. Further, the display device 1 increases the number of images to be displayed representing the contents of the image data when the detection unit 5 detects an operation to increase the interval between a plurality of operation inputs for the image displayed on the display screen. It has the control part 6 displayed on this.

  Note that the operation of increasing the interval between a plurality of operation inputs is, for example, pinching out to increase the interval between two fingers touching the display screen.

  With such a configuration, the display device 1 can allow the user to confirm the content of the moving image data while changing the number of displayed images representing the content of the moving image data with a more intuitive operation.

  A specific example of the display device 1 having such a configuration will be described in detail below.

[1-2. Hardware configuration of digital video camera]
First, the hardware configuration of a digital video camera (hereinafter also referred to as DVC), which is a specific example of the display device 1 described above, will be described with reference to FIG. In the DVC 100, the CPU 101 reads out the program written in the ROM 102 to the RAM 103 and executes it, and executes various processes, and controls each unit in accordance with input signals from the touch panel 104 and the operation unit 105.

  Incidentally, CPU is an abbreviation for Central Processing Unit, ROM is an abbreviation for Read Only Memory, and RAM is an abbreviation for Random Access Memory.

  The touch panel 104 is a device that constitutes the touch screen 107 together with the liquid crystal display 106. When an arbitrary position on the touch panel 104 is touched with a finger, the touched position (that is, the touch position) is detected. The touch panel 104 sends an input signal indicating the coordinates of the touch position to the CPU 101.

  Note that the touch panel 104 is configured to send an input signal indicating the coordinates of the touch position to the CPU 101 at regular intervals while being touched, such as when being dragged.

  When the CPU 101 obtains the coordinates of the touch position from the input signal sent from the touch panel 104, the CPU 101 converts the coordinates into the screen coordinates of the liquid crystal display 106, which position on the screen of the liquid crystal display 106 is touched. Recognize That is, the touch position on the screen is recognized.

  Further, the CPU 101 sequentially converts the coordinates of the touch position acquired from the input signal sent at regular intervals to the screen coordinates of the liquid crystal display 106, so that the touch position has moved (that is, the touch position). Recognize the position trajectory.

  Then, the CPU 101 determines what touch operation has been performed on which position on the screen based on the touch position recognized in this way and its locus.

  On the other hand, the operation unit 105 is a device including a shooting button, a playback button, a mark button, a power button, and the like, and sends an input signal corresponding to these operations to the CPU 101.

  Based on the input signal sent from the operation unit 105, the CPU 101 determines which of the shooting button, the playback button, the mark button, and the power button has been operated.

  Actually, the CPU 101 operates in the photographing mode when the power button of the operation unit 105 is pressed and the power is turned on or when the operation mode is instructed to be switched to the photographing mode by a touch operation on the touch panel 104.

  Then, under the control of the CPU 101, the imaging unit 108 obtains an analog image signal by converting light from a subject captured via a lens (not shown) into an electrical signal (that is, photoelectric conversion) by the imaging device. Then, the imaging unit 108 converts this image signal into a digital image signal, and then sends it to the CPU 101.

  The CPU 101 sends the image data sent from the imaging unit 108 to the display processing unit 109. The display processing unit 109 sends this image signal to the liquid crystal display 106. As a result, the image of the subject is displayed on the liquid crystal display 106 as a monitoring image as it is. By doing so, the DVC 100 can make the photographer confirm the subject.

  At this time, the display processing unit 109 generates graphics signals such as menus and icons under the control of the CPU 101 and superimposes them on the image signals. As a result, on the liquid crystal display 106, menus, icons, and the like are displayed together with the monitoring image.

  Here, it is assumed that the photographing button of the operation unit 105 is pressed. Then, the CPU 101 starts recording a moving image.

  That is, the CPU 101 generates moving image data by compressing the image signal sent from the imaging unit 108 in a predetermined moving image format. Further, the CPU 101 generates audio data by compressing an audio signal input from the microphone 110 via the analog-digital converter 111 in a predetermined audio format.

  Then, the CPU 101 generates moving image sound data by multiplexing the moving image data and the sound data, writes the moving image sound data back to the RAM 103, and then stores it in the storage medium 112. . Incidentally, the storage medium 112 may be built in the DVC 100 in advance, or may be removable from the DVC 100 like a memory card.

  Thereafter, when the shooting button is pressed again, the CPU 101 ends the recording of the moving image.

  That is, the CPU 101 stores the moving image audio data remaining in the RAM 103 at this time in the storage medium 112. As a result, a series of moving image audio data from the start to the end of shooting is stored in the storage medium 112.

  Then, the CPU 101 adds header information to the moving image audio data to store the moving image file in the storage medium 112 as a moving image file. The header information includes a file name, a file creation date and time, a file size, and the like. In this way, the DVC 100 is configured to record a moving image.

  A series of moving images from the start to the end of shooting is also called a scene. That is, one moving image file is stored in the storage medium 112 for each scene.

  Further, the CPU 101 manages all moving image files stored in the storage medium 112 with one moving image management file stored in the storage medium 112.

  In this moving image management file, for each moving image file stored in the storage medium 112, a file name, a shooting start date and time, a scene length, and a thumbnail image of the first frame of the scene (this is also referred to as a first image). It is registered as management information. The scene length is the time from the beginning to the end of the scene.

  That is, every time a moving image file is stored in the storage medium 112 (that is, every time a moving image is recorded), the CPU 101 generates management information for the stored moving image file and additionally registers it in the moving image management file. It has become.

  The management information of each moving image file registered in this moving image management file and each moving image file stored in the storage medium 112 are associated with each other by, for example, a file name. The head image registered as management information is generated by the CPU 101 by resizing the head frame of the scene.

  Further, the CPU 101 can set an arbitrary time point of the moving image being recorded as a favorite point in response to the pressing of the mark button on the operation unit 105 in the shooting mode.

  The CPU 101 registers the favorite points set in this way in the moving image management file as moving image file management information.

  That is, for a moving image file in which favorite points are set, favorite points are registered as management information in addition to the file name, shooting start date and time, scene length, and top image. The favorite point is indicated by the elapsed time from the beginning of the scene, for example.

  On the other hand, when the playback button of the operation unit 105 is pressed or when an instruction to switch the operation mode to the playback mode is given by a touch operation on the touch panel 104, the CPU 101 operates in the playback mode.

  Then, the CPU 101 reads out the moving image management file from the storage medium 112 to the RAM 103.

  The CPU 101 cooperates with the display processing unit 109 on the basis of the management information of each moving image file registered in the moving image management file, and displays a moving image file list screen (also referred to as a moving image list screen). A screen display signal is generated.

  This screen display signal is sent from the display processing unit 109 to the liquid crystal display 106. As a result, a moving image list screen Ms as shown in FIG.

  On this moving image list screen Ms, thumbnail images Tp extracted from each scene are displayed in chronological order so that the user can visually recognize the contents (that is, the contents of the scene) of each moving image file. Yes. Incidentally, extracting the thumbnail image Tp from each scene means that the CPU 101 actually obtains the thumbnail image Tp by extracting a frame from each scene and resizing the frame.

  As shown in FIG. 3, the moving image list screen Ms includes a thumbnail display area ARp in which thumbnail images Tp extracted from each scene are displayed in time series and scene information in which scene information such as a shooting period is displayed. And display area ARs.

  The thumbnail display area ARp is a rectangular area that occupies almost the entire moving image list screen Ms, and the scene information display area ARs is a band-shaped area positioned at the upper end of the moving image list screen Ms.

  Further, the thumbnail display area ARp is divided into four in the vertical direction by four horizontally long row areas ARp1 to ARp4.

  In each of the four row regions ARp1 to ARp4, thumbnail images Tp extracted from each scene are displayed side by side in order of time series (in order of shooting date and time) from the left end to the right end. Here, the right end of the first row area (that is, the uppermost) row area ARp1 and the left edge of the second row area ARp2 are temporally connected. The right end of the second row area ARp2 and the left end of the third row area ARp3, and the right end of the third row area ARp3 and the left end of the fourth row (that is, the bottom) row area ARp4 Connected.

  Therefore, in the thumbnail display area ARp, the thumbnail images Tp extracted from each scene are displayed in time series order (in order of shooting date / time) from the left end of the top row area ARp1 to the bottom row area ARp4. Displayed side by side to the right edge.

  Depending on the number of moving image files stored in the storage medium 112, all thumbnail images Tp extracted from each scene may not be displayed at once in the thumbnail display area ARp.

  In this case, a scroll bar (not shown) for vertical scrolling is displayed at the right end of the thumbnail display area ARp, for example. In the moving image list screen Ms, the thumbnail images Tp displayed in the thumbnail display area ARp are scrolled vertically, for example, line by line in response to a touch operation on the scroll bar.

  As a result, even when all the thumbnail images Tp extracted from each scene cannot be displayed at a time, all the thumbnail images Tp can be sequentially confirmed by the user.

  Further, the display interval of the thumbnail images Tp displayed side by side in the row areas ARp1 to ARp4 is set to be wider at the boundary between scenes than in the same scene. Thereby, when the thumbnail images Tp are displayed side by side in the row areas ARp1 to ARp4, the user can easily recognize the boundary between the scenes.

  Furthermore, when displaying thumbnail images Tp in the thumbnail display area ARp, n (n is an integer of 1 or more) thumbnail images Tp corresponding to the length of the scene are extracted from each scene. . As shown in FIG. 4, the CPU 101 always extracts at least one of the first images Tp (s) of the scene from each scene.

  Accordingly, the contents of each scene (that is, the contents of each moving image file) can be easily recognized by the user, and the length of the scene can be recognized from the number of thumbnail images Tp displayed for each scene.

  Further, a notch Ch is formed in the upper left corner of the leading image Tp (s) extracted from each scene. Thereby, even when the boundary between the scenes is positioned at the right end of the row area ARp1, for example, the user can easily recognize the boundary between the scenes.

  Further, a shooting start time Pt of a scene starting from the top image Tp (s) is displayed near the top of the top image Tp (s). This makes it possible for the user to easily recognize when each scene (that is, each moving image file) is a captured scene.

  Further, as shown in FIG. 5, a thumbnail image (also referred to as a favorite image) Tp (m) of a frame corresponding to the favorite point is preferentially extracted from the scene where the favorite point is set. It has become. Even when the favorite image Tp (m) is preferentially extracted in this way, the top image Tp (s) is always extracted and the number of thumbnail images Tp corresponding to the length of the scene. Is not changed.

  That is, when extracting n thumbnail images Tp from the scene, the CPU 101 preferentially extracts the favorite image Tp (m) after the top image Tp (s).

  This allows the user to recognize the portion of the favorite point for the scene where the favorite point is set.

  Further, a triangular mark Mk is displayed in the upper left corner of the favorite image Tp (m). As a result, the user can easily recognize which scene has the favorite point set and which thumbnail image Tp is the favorite image Tp (m).

  Assume that the thumbnail image Tp is flicked rightward on the screen while the thumbnail image Tp is displayed on the moving image list screen Ms in this way. Note that flicking is an operation of lightly touching the touch panel 104 with a finger (or a pen or the like).

  Then, the CPU 101 cooperates with the display processing unit 109 to generate a window display signal that becomes a moving image file reproduction window (also referred to as a moving image reproduction window).

  The display processing unit 109 superimposes this window display signal on the screen display signal of the moving image list screen Ms. As a result, as shown in FIG. 6, a moving image reproduction window Mp is displayed on the liquid crystal display 106 so as to overlap the moving image list screen Ms.

  The moving image reproduction window Mp is composed of a moving image display area ARm where the reproduced moving image is displayed, and a button display area ARb where various buttons related to reproduction are displayed.

  The moving image display area ARm is a rectangular area that occupies almost the entire moving image reproduction window Mp, and the button display area ARb is a band-shaped area positioned at the lower end of the moving image reproduction window Mp.

  In the button display area ARb, a rewind button B1, a fast forward button B2, a pause / play button B3, and a stop button B4 are displayed. The button display area ARb includes a slide bar Ps that indicates the current playback position and can arbitrarily change the playback position, an elapsed time T1 that indicates the current playback position, and a playback time T2 that indicates the time length of the moving image. Is displayed.

  Further, a close button B5 for closing the moving image window Mp is displayed in the upper right corner of the moving image reproduction window Mp.

  The CPU 101 displays such a moving image reproduction window Mp, and reads a moving image file corresponding to the flicked thumbnail image Tp from the storage medium 114 to the RAM 103.

  Further, the CPU 101 extracts moving image audio data from the moving image file read out to the RAM 103 and separates it into moving image data and audio data.

  Then, the CPU 101 obtains the original image signal by expanding the moving image data in the same moving image format as when it was compressed, and writes it back to the RAM 103.

  The CPU 101 obtains the original audio signal by decompressing the audio data in the same audio format as when it was compressed, and writes it back to the RAM 103.

  The CPU 101 reads out an image signal from the RAM 103 and sends it to the display processing unit 109, and reads out an audio signal from the RAM 103 and sends it to the digital / analog converter 113.

  The display processing unit 109 superimposes this image signal on the window signal of the moving image reproduction window Mp. As a result, a moving image is displayed in the moving image display area ARm of the moving image reproduction window Mp displayed on the liquid crystal display 106.

  At this time, an audio signal is sent to the speaker 114 via the digital / analog converter 113. As a result, sound is output from the speaker 114.

  In this way, the DVC 100 reproduces a moving image file corresponding to the flicked thumbnail image Tp, and outputs a moving image and sound.

  Further, when the moving image file is reproduced in this way, the CPU 101 starts reproduction from a frame corresponding to the thumbnail image Tp located at the start point of the flick.

  That is, for example, when a flick starting from an arbitrary position on the top image Tp (s) is performed, the CPU 101 starts playback from the top of the scene. On the other hand, when a flick starting from an arbitrary position on the thumbnail image Tp other than the top image Tp (s) is performed, reproduction is started from a frame corresponding to the thumbnail image Tp.

  Thereby, when a moving image file is reproduced, reproduction can be started from a position desired by the user in the scene.

  Further, the CPU 101 performs reproduction control on the moving image file in accordance with various buttons B1 to B4 displayed in the button display area ARb of the moving image reproduction window Mp and the touch operation on the slide bar Ps.

  Further, the CPU 101 stops the reproduction of the moving image file and closes the moving image reproduction window Mp in response to a touch operation on the close button B5 of the moving image reproduction window Mp.

  In this way, on the moving image list screen Ms, the user can recognize the contents of each scene (the contents of each moving image file) and the length of each scene, and further, a desired scene (moving image file) can be desired. It can be viewed from the position of.

  Further, on the moving image list screen Ms, the number of thumbnail images Tp displayed in each scene (also referred to as the number of thumbnails displayed) can be changed in accordance with the pinch-out or pinch-in to the thumbnail image Tp.

  Note that the pinch-out is a touch operation in which two fingers are touched at two locations and the interval between the two fingers is increased. The pinch-in is a touch operation that narrows the interval between these two fingers.

  Specifically, the CPU 101 changes the number of thumbnail images Tp extracted from each scene according to the amount of pinch-out or pinch-in operation (that is, the amount of change in the interval between two touch positions).

  Since the thumbnail images Tp are displayed side by side in the horizontal direction on the moving image list screen Ms, the horizontal operation amount, that is, the horizontal change amount of the touch position interval is used here. The number of thumbnail images Tp extracted from each scene is also called the number of thumbnail extractions, and is represented by n (n is an integer of 1 or more). Further, the CPU 101 changes the thumbnail extraction number n not only for the touched scene but also for all scenes.

  Actually, as shown in FIGS. 7A and 7B, when the horizontal operation amount of the pinch-out reaches one horizontal width of the thumbnail image Tp, the CPU 101 sets the thumbnail extraction number n of each scene to the present. The number of extracted thumbnails is changed to n + 1.

  Then, the CPU 101 re-extracts the thumbnail image Tp from each scene based on the changed thumbnail extraction number n, and re-displays it in the thumbnail display area ARp. As a result, the number of thumbnails displayed for each scene is increased by one from before the pinch out.

  Thereafter, when the amount of pinch-out operation in the horizontal direction reaches two horizontal widths of the thumbnail image Tp as shown in FIG. 7C, the CPU 101 sets the thumbnail extraction number n of each scene to the current thumbnail extraction number. Change to n + 1. As a result, the number n of thumbnail extractions is increased by two from before the pinch out.

  Then, the CPU 101 re-extracts the thumbnail image Tp from each scene based on the changed thumbnail extraction number n, and re-displays it in the thumbnail display area ARp. As a result, the number of thumbnails displayed for each scene is further increased by one. In other words, the number of thumbnails displayed has increased by two from before the pinch out.

  Similarly, the number of thumbnails to be displayed is increased by 3 images before the pinch out if the amount of operation in the horizontal direction of the pinch out is 3 for the horizontal width of the thumbnail image Tp, and is 4 before the pinch out if the amount is 4 Will increase by 4 cards.

  In this way, on the moving image list screen Ms, the number of thumbnails displayed for each scene increases in accordance with the amount of pinch-out operation, so that the user can easily check the detailed contents of each scene.

  At this time, not only the touched scene but also the number of thumbnails displayed for all scenes increases in the same manner, so that the relationship between the number of thumbnails displayed for each scene and the length of the scene can be maintained.

  That is, on this moving image list screen Ms, even after the number of thumbnails displayed increases due to pinch out, the user can recognize the length of the scene from the number of thumbnails displayed for each scene.

  On the other hand, as shown in FIGS. 8A and 8B, when the amount of pinch-in operation in the horizontal direction reaches one horizontal width of the thumbnail image Tp, the CPU 101 determines the thumbnail extraction number n of each scene. Change to the current thumbnail extraction number n-1.

  Then, the CPU 101 re-extracts the thumbnail image Tp from each scene based on the changed thumbnail extraction number n, and re-displays it in the thumbnail display area ARp. As a result, the number of thumbnails displayed for each scene is reduced by one from before the pinch-in.

  Similarly, the number of thumbnails displayed is 2 less than before pinch-in when the amount of operation in the horizontal direction of pinch-in reaches 2 horizontal widths of the thumbnail image Tp, and 3 more than before pinch-in when reaching 3 images. Decrease.

  As described above, in the moving image list screen Ms, the number of thumbnails displayed for each scene is reduced according to the amount of pinch-in operation, and the number of scenes displayed at a time in the thumbnail display area ARp is increased. Can be confirmed by the user.

  Note that the thumbnail extraction number n is an integer equal to or greater than 1 (because at least one leading image Tp (s) is extracted), and when the thumbnail extraction number n after change is less than 1 due to pinch-in, It is corrected to 1. That is, the number of thumbnails to be displayed decreases according to the amount of pinch-in operation, but at least one thumbnail remains.

  This completes the description of the hardware configuration of the DVC 100. The CPU 101 of the DVC 100 is hardware corresponding to the storage control unit 3 of the display device 1 described above. The liquid crystal display 106 of the DVC 100 is hardware corresponding to the display unit 4 of the display device 1. Furthermore, the touch panel 104 and the CPU 101 of the DVC 100 are hardware corresponding to the detection unit 5 of the display device 1 described above. Further, the CPU 101 of the DVC 100 is hardware corresponding to the control unit 6 of the display device 1. In the DVC 100, the CPU 101 and the touch panel 104 cooperate to realize a function equivalent to that of the detection unit 5 of the display device 1.

[1-3. Thumbnail display processing procedure]
Next, a procedure for extracting the thumbnail image Tp from the scene of each moving image file and displaying it in the thumbnail display area ARp (this is also referred to as a thumbnail display processing procedure) will be described in detail.

  Incidentally, this thumbnail display processing procedure is a processing procedure executed by the CPU 101 of the DVC 100 in accordance with a program written in the ROM 102.

  When the CPU 101 switches to the playback mode, the moving image list screen Ms is displayed on the liquid crystal display 106, and the thumbnail display processing procedure RT1 shown in FIG. 9 is started, and the process proceeds to step SP1.

  In step SP1, the CPU 101 selects one of all moving image files (that is, one of all scenes) and then sets an extraction number setting processing procedure SRT1 (FIG. 10) for setting the thumbnail extraction number n of this scene. ) And the process proceeds to step SP20.

  In step SP20, the CPU 101 sets N (an integer of 1 or more) thresholds 1 to N for the length of the scene, and proceeds to the next step SP21. Specifically, the thresholds 1 to N are thresholds for classifying scene lengths. For example, N = 3, threshold 1 = 30 seconds, threshold 2 = 90 seconds, threshold 3 = 150 seconds. Set. In this case, the scene length is classified into four types: 30 seconds or less, more than 30 seconds and 90 seconds or less, more than 90 seconds and 150 seconds or less, and more than 150 seconds.

In step SP21 ₁ CPU 101 determines whether the length of the scene is the threshold value 1 or less. Here, by the length of the scene is the threshold value 1 or less, if an affirmative result is obtained, CPU 101 proceeds to step SP21 _2.

In step 21 ₂ CPU 101 sets the thumbnail extraction number n which is the number of thresholds in this case "1" (i.e. one top image Tp (s) only), ends the extraction number setting procedure SRT1 To do.

In contrast, by the length of the scene is a threshold greater than 1, a negative result is obtained at step SP21 ₁ described above, or CPU101 shifts to the step SP21 _2, is the length of the scene is the threshold 2 or less Determine whether or not. Here, by the length of the scene is the threshold value 1 supra-threshold 2 or less, upon obtaining a positive result, CPU 101 proceeds to step SP22 _2.

In step SP22 ₂ CPU 101 is a threshold number of this time the thumbnail extraction number n "2" (i.e. the top image Tp (s) is a single + thumbnail image Tp two in total of one image) is set to The extraction number setting process procedure SRT1 is terminated.

In contrast, by the length of the scene is the threshold value 2 greater, if the negative result is obtained in step SP21 ₂ described above, since, CPU 101, while changing the order of the threshold to the threshold N-1, the length of the scene Whether or not is equal to or less than a threshold value is determined. Then, the CPU 101 sets the threshold number when the scene length is equal to or smaller than the threshold as the thumbnail extraction number n.

Further, CPU 101, by the length of the scene is the threshold N-1 than, turning to step SP21 _N, to determine whether the length of the scene is less than the threshold value N. Here, by the length of the scene is equal to or less than the threshold N-1 supra-threshold N, we obtain a positive result, CPU 101 proceeds to step SP22 _N.

In step SP22 _N , the CPU 101 sets the thumbnail extraction number n to “N”, which is the threshold number at this time (that is, the top image Tp (s) is one + the thumbnail image Tp is N−1 total N). Then, this extraction number setting processing procedure SRT1 is completed.

In contrast, by the length of the scene is the threshold value N exceeds, if the negative result is obtained in the above step SP21 _N, CPU 101 proceeds to step SP22 _{N + 1.}

In step SP22 _{N + 1} , the CPU 101 sets the thumbnail extraction number n to “N + 1” (that is, the top image Tp (s) is 1 + the thumbnail image Tp is N + 1 in total), and this extraction number setting processing procedure SRT1. Exit.

  N + 1 is the maximum number n of thumbnail extractions. For example, when N = 3, threshold 1 = 30 seconds, threshold 2 = 90 seconds, threshold 3 = 150 seconds, a scene exceeding 150 seconds is set. For, the thumbnail extraction number n is set to the maximum value “4”.

  After setting the thumbnail extraction number n by such an extraction number setting processing procedure SRT1, the CPU 101 proceeds to the next step SP2 (FIG. 9).

  In step SP2, the CPU 101 sets n points for extracting thumbnail images Tp from the scene (also referred to as thumbnail extraction points) according to the number n of thumbnail extractions.

  At this time, the CPU 101 first sets the top of the scene as a thumbnail extraction point in order to extract the top image Tp (s). Further, the CPU 101 calculates a time T obtained by dividing the length of the scene (that is, the time from the beginning to the end of the scene) by the number n of thumbnail extractions. That is, this time T is a time obtained by dividing the length of the scene into n equal parts (also referred to as an equal time). For example, if the number of thumbnails extracted is n = 3 in a 96-second scene, it is 32 seconds. Become.

  Then, the CPU 101 calculates a position at which the scene is equally divided into n parts (this is also referred to as an equally divided position and is represented by an elapsed time from the beginning of the scene) based on the equally divided time T. Set the equal position as the thumbnail extraction point. Specifically, for example, as shown in FIG. 11, the equally divided position where the scene is divided into n is 96 seconds, and if the number of thumbnails extracted is n = 3, it is 32 seconds after the beginning of the scene. There are two places (n-1 places) after 64 seconds.

  In this way, the CPU 101 sets a total of n locations including the beginning of the scene and n-1 locations that equally divide the scene into n as thumbnail extraction points, and proceeds to the next step SP3.

  In step SP3, the CPU 101 selects one of the n thumbnail extraction points set in step SP2, and determines whether or not a favorite point is set near the thumbnail extraction point.

  Specifically, as shown in FIG. 12, the CPU 101 sets the search range H of the favorite point search range H as the favorite point search range H, with the range of the equal divided period T / 2 around the selected thumbnail extraction point. Search for favorite points. The search range H includes thumbnail extraction points themselves.

  As for the last thumbnail extraction point among the n thumbnail extraction points, the search range H is extended to the end of the scene as shown in FIG.

  Further, the search range H is not set for the first thumbnail extraction point. That is, when the first thumbnail extraction point is selected, the CPU 101 always obtains a negative result in this step SP3.

  If a negative result is obtained in step SP3, this means that no favorite point is set in the vicinity of the selected thumbnail extraction point, or that the selected thumbnail extraction point is the first thumbnail extraction point. means. At this time, the CPU 101 proceeds to step SP4.

  In step SP4, the CPU 101 extracts the thumbnail image Tp of the frame corresponding to the thumbnail extraction point from the selected scene, and proceeds to step SP5. At this time, if there is a frame at a time completely matching the thumbnail extraction point, the CPU 101 sets this frame as the frame corresponding to the thumbnail extraction point. On the other hand, if there is no frame with a completely matching time, the frame with the time closest to the thumbnail extraction point is set as the frame corresponding to the thumbnail extraction point.

  In step SP5, the CPU 101 determines whether n thumbnail images Tp have been extracted from the selected scene. If a negative result is obtained in step SP5, the CPU 101 returns to step SP3 again and selects the next thumbnail extraction point.

  On the other hand, if a positive result is obtained in step SP3 described above, this means that a favorite point is set in the vicinity of the selected thumbnail extraction point. At this time, the CPU 101 proceeds to step SP6.

  In step SP6, the CPU 101 determines whether or not the number of favorite points set in the vicinity of the selected thumbnail extraction point is one. That is, the CPU 101 determines whether or not the number of favorite points set in the search range H centered on the selected thumbnail extraction point is one.

  If the number of favorite points set in the search range H centered on the selected thumbnail extraction point is one and if an affirmative result is obtained in step SP6, the CPU 101 proceeds to step SP7.

  In step SP7, the CPU 101 extracts the thumbnail image Tp of the frame corresponding to the favorite point instead of the selected thumbnail extraction point, and proceeds to the next step SP5.

  On the other hand, if the number of favorite points set in the search range H centering on the selected thumbnail extraction point is two or more, if a negative result is obtained in step SP6, the CPU 101 Moves to step SP8.

  In step SP8, the CPU 101 selects one of the plurality of favorite points closest to the selected thumbnail extraction point, extracts the thumbnail image Tp of the frame corresponding to the favorite point, and proceeds to step SP5.

  In step SP5, the CPU 101 determines whether or not n thumbnail images Tp have been extracted from the selected scene. If a negative result is obtained in step SP5, the CPU 101 returns to step SP3 again and selects the next thumbnail extraction point.

  In this manner, the CPU 101 selects n thumbnail extraction points one by one in order until the extraction of n thumbnail images Tp is completed, and repeats steps SP3 to SP8 to extract the thumbnail image Tp from the scene. Extract one by one.

  After extracting n thumbnail images Tp from the scene, the CPU 101 obtains a positive result in step SP5, and proceeds to step SP9.

  In step SP9, the CPU 101 determines whether or not the thumbnail images Tp have been extracted from all scenes. If a negative result is obtained in step SP9, the CPU 101 returns to step SP1 again and selects the next scene.

  In this manner, the CPU 101 selects the scenes one by one until the extraction of the thumbnail images Tp from all the scenes and repeats steps SP1 to SP9, thereby extracting the thumbnail images Tp from each scene.

  When the thumbnail images Tp have been extracted from all scenes (that is, all moving image files), the CPU 101 obtains an affirmative result at step SP9 and proceeds to step SP10.

  Here, extraction examples of the thumbnail images Tp from each scene are shown in FIGS. 14A to 14D and FIG. FIG. 14 and FIG. 15 are examples of extraction when two threshold values of threshold value 1 = 30 seconds and threshold value 2 = 90 seconds are set for the length of the scene.

  14A to 14D are examples of extraction of thumbnail images Tp from scenes for which no favorite points are set, and FIG. 15 is an example of extraction of thumbnail images Tp from scenes for which favorite points are set. It is.

  FIG. 14A shows an example of extraction from scene 1 (no favorite points) for 34 seconds. In this case, since the length of the scene 1 is greater than the threshold value 1 and less than or equal to the threshold value 2, the thumbnail extraction number n is set to “2”, which is the threshold value 2 number. The thumbnail extraction point is set 17 seconds after the beginning of the scene 1 and the equally divided position that is divided into two equal parts. Therefore, from this scene 1, the leading image Tp (s) and the thumbnail image Tp of the frame after 17 seconds are extracted.

  FIG. 14B shows an extraction example from scene 2 (no favorite points) for 96 seconds. In this case, since the length of the scene 2 is greater than the threshold value 2, the number n of thumbnail extractions is set to “3”, which is the threshold number 2 + 1. The thumbnail extraction points are set at the beginning of the scene 2, 32 seconds after the equally divided position, and 64 seconds later. Therefore, from this scene 1, the head image Tp (s), the thumbnail image Tp of the frame after 32 seconds, and the thumbnail image Tp of the frame after 64 seconds are extracted.

  FIG. 14C shows an example of extraction from scene 3 (no favorite points) at 9 minutes 30 seconds. In this case, since the length of the scene 3 is greater than the threshold value 2, the thumbnail extraction number n is set to “3”, which is the threshold number 2 + 1. The thumbnail extraction points are set at the beginning of the scene 3, after 3 minutes and 10 seconds, which are equally divided into 3 parts, and after 6 minutes and 20 seconds. Therefore, from this scene 1, the top image Tp (s), the thumbnail image Tp of the frame after 3 minutes and 10 seconds, and the thumbnail image Tp of the frame after 6 minutes and 20 seconds are extracted.

  FIG. 14D shows an example of extraction from scene 4 (no favorite points) for 12 seconds. In this case, since the length of the scene 4 is equal to or less than the threshold value 1, the thumbnail extraction number n is set to the threshold value 1 number “1”. The thumbnail extraction point is set only at the beginning of the scene 4. Therefore, only the thumbnail image Tp of the frame of the top image Tp (s) is extracted from the scene 4.

  FIG. 15 is an example of extraction from scene 5 (with favorite points) for 96 seconds. In this case, since the length of the scene 5 is greater than the threshold value 2, the thumbnail extraction number n is set to “3”, which is the threshold number 2 + 1. The thumbnail extraction points are set at the beginning of the scene 5, after 32 seconds, which are equally divided into three, and after 64 seconds. In this scene 5, a favorite point is set after 72 seconds. Therefore, from this scene 5, the leading image Tp (s), the thumbnail image Tp of the frame after 32 seconds, and the favorite image Tp (m) of the frame after 72 seconds are extracted.

  In this way, the CPU 101 extracts the thumbnail image Tp from each scene. In step SP10 (FIG. 9), the CPU 101 displays the thumbnail image Tp extracted from each scene in the thumbnail display area ARp, and ends this thumbnail display processing procedure RT1.

  With such a thumbnail display processing procedure RT1, the DVC 100 extracts the thumbnail image Tp from the scene of each moving image file and displays it in the thumbnail display area ARp.

[1-4. Procedure for changing the number of thumbnails displayed]
Next, a procedure of processing for changing the number of thumbnails displayed for each scene according to the amount of pinch-out or pinch-in for the thumbnail image Tp (this is also referred to as a thumbnail display number change processing procedure) will be described in detail.

  Incidentally, this thumbnail display number change processing procedure is also a processing procedure executed by the CPU 101 of the DVC 100 in accordance with a program written in the ROM 102.

  When the CPU 101 displays the moving image list screen Ms, the CPU 101 starts the thumbnail display number change processing procedure RT2 shown in FIG. 16, and proceeds to step SP30.

  In step SP30, the CPU 101 determines whether or not any two locations on the thumbnail image Tp displayed in the thumbnail display area ARp are touched.

  Here, if a negative result is obtained, this means that no one is touched or only one place is touched. At this time, the CPU 101 returns to step SP30. Then, the CPU 101 waits for any two places on the thumbnail image Tp in the same scene to be touched.

  On the other hand, if any two locations on the thumbnail image Tp in the same scene are touched, and if a positive result is obtained in step SP30 described above, the CPU 101 proceeds to step SP31.

  In step SP31, the CPU 101 determines whether pinch-out or pinch-in has been performed.

  Specifically, the CPU 101 recognizes two touch positions immediately after being touched based on an input signal from the touch panel 104. Further, the CPU 101 calculates the interval between the two touch positions (that is, the initial interval), and stores this in the RAM 103.

  Thereafter, every time an input signal is sent, the CPU 101 calculates the interval between the touch positions, and subtracts the initial interval from the calculated interval, thereby obtaining the change amount between the two touch positions.

  Then, the CPU 101 determines that a pinch-out or a pinch-in has been performed when the amount of change is not 0 (may be substantially 0), that is, when the interval between the two touch positions changes from the initial interval.

  Actually, when the change amount is 0 (may be substantially 0), when it is determined that the pinch out or the pinch in is not performed, the CPU 101 obtains a negative result in this step SP31, and returns to the step SP30 again.

  On the other hand, when it is determined that the pinch out or the pinch in has been performed because the change amount is not 0 (may be substantially 0), the CPU 101 obtains an affirmative result in step SP31 and proceeds to step SP32.

  In step SP32, the CPU 101 changes the thumbnail extraction number n of each scene in accordance with the amount of pinch-out or pinch-in operation (that is, the amount of change in the interval between two touch positions).

  Specifically, it is assumed that the sign of the amount of change in the interval between the two touch positions is + (that is, the interval between the two touch positions is wider than the initial interval). At this time, the CPU 101 determines that a pinch out has been performed.

  Then, the CPU 101 increases the number n of thumbnail extractions for each scene according to the amount of change in the interval between the two touch positions (that is, the amount of pinch-out operation). Actually, the CPU 101 increases the thumbnail extraction number n of each scene to the current thumbnail extraction number n + 2 if the amount of pinch-out operation is, for example, two horizontal widths of the thumbnail image Tp.

  On the other hand, it is assumed that the sign of the change amount of the interval between the two touch positions is − (that is, the interval between the two touch positions is narrower than the initial interval). At this time, the CPU 101 determines that pinch-in has been performed.

  Then, the CPU 101 reduces the thumbnail extraction number n of each scene according to the change amount of the interval between the two touch positions (that is, the amount of pinch-in operation). Actually, if the amount of pinch-in operation is, for example, one horizontal width of the thumbnail image Tp, the CPU 101 reduces the thumbnail extraction number n of each scene to the current thumbnail extraction number n-1.

  After changing the thumbnail extraction number n of each scene in accordance with the pinch-out or pinch-in operation amount in this way, the CPU 101 proceeds to the next step SP33.

  In step SP33, the CPU 101 re-extracts the thumbnail image Tp from each scene based on the thumbnail extraction number n changed in step SP32 and re-displays it in the thumbnail display area ARp. As a result, the number of thumbnails displayed for each scene displayed in the thumbnail display area ARp changes.

  Here, an example of changing the number of thumbnails displayed is shown in FIG. FIG. 17 shows an example of a change when a pinch-out is performed for a 96-second scene with the thumbnail extraction number n set to “3”.

  First, before the pinch-out is performed, the thumbnail extraction points of this scene are set at the beginning of the scene, 32 seconds after being equally divided into three, and 64 seconds later. Therefore, from this scene, three images, ie, the first image Tp (s), the thumbnail image Tp of the frame after 32 seconds, and the thumbnail image Tp of the frame after 64 seconds are extracted and displayed in the thumbnail display area ARp. The

  Here, for example, it is assumed that two arbitrary positions on the thumbnail image Tp are touched, and the interval between the two touch positions is expanded by one horizontal width of the thumbnail image Tp due to pinch-out. Then, the CPU 101 changes the thumbnail extraction number n from “3” to “4”.

  Then, the CPU 101 resets the thumbnail extraction points at the beginning of the scene, and after 24 seconds, 48 seconds, and 72 seconds, which are equally divided positions. As a result, from this scene, there are four images, the first image Tp (s), the thumbnail image Tp of the frame after 24 seconds, the thumbnail image Tp of the frame after 48 seconds, and the frame thumbnail image Tp after 72 seconds. Are extracted and displayed in the thumbnail display area ARp.

  In this way, after changing the number of thumbnails displayed for each scene according to the amount of pinch-out or pinch-in operation, the CPU 101 stores the current interval between the two touch positions in the RAM 103 as a new initial interval, The process returns to step SP30. Then, while the moving image list screen Ms is being displayed, the CPU 101 increases / decreases the number of thumbnails displayed according to the amount of operation each time pinch-out or pinch-in is performed.

  By such a thumbnail display number change processing procedure RT2, the DVC 100 changes the number of thumbnails displayed for each scene according to the operation amount of pinch-out or pinch-in.

[1-5. Operation and Effect According to First Embodiment]
In the above configuration, the CPU 101 of the DVC 100 extracts the thumbnail image Tp from each moving image file scene stored in the storage medium 112 and displays the thumbnail image Tp in the thumbnail display area ARp.

  Here, the CPU 101 extracts n (n is an integer of 1 or more) thumbnail images Tp corresponding to the length of the scene from each scene. Then, the CPU 101 displays n thumbnail images Tp extracted from each scene, grouped for each scene, and arranged and displayed in chronological order.

  In this way, the CPU 101 allows the user to easily recognize the contents of each scene (that is, the contents of each moving image file), and recognizes the length of each scene from the number of thumbnail images Tp displayed for each scene. Can be made.

  Further, the CPU 101 preferentially extracts the thumbnail image (favorite image) Tp (m) of the frame corresponding to the favorite point from the scene where the favorite point is set.

  By doing this, the CPU 101 can make the user recognize the portion of the favorite point for the scene where the favorite point is set.

  Thus, the DVC 100 can always allow the user to confirm the length of each scene from the number of thumbnails displayed, and can also confirm the thumbnail image of the favorite point of the scene.

  Further, the CPU 101 changes the number of thumbnails displayed for each scene in accordance with the pinch out or the pinch in for the thumbnail image Tp displayed in the thumbnail display area ARp.

  That is, the CPU 101 increases the number of thumbnails displayed for each scene according to the amount of pinch-out operation. In this way, the CPU 101 can make the user easily check the detailed contents of each scene.

  In addition, the CPU 101 reduces the number of thumbnails displayed for each scene according to the amount of pinch-in operation. By doing so, the number of scenes displayed at a time in the thumbnail display area ARp increases, and as a result, the user can confirm more scenes at a time.

  Thus, the DVC 100 can allow the user to confirm each scene while changing the number of thumbnail images Tp representing the contents of each scene (that is, moving image data) by an intuitive operation such as pinch-out.

  According to the above configuration, the DVC 100 increases the number of thumbnail images Tp representing the contents of the scene (that is, moving image data) in accordance with the pinch out. In addition, the number of thumbnail images Tp representing scene contents is reduced in accordance with the pinch-in. In this way, the DVC 100 can allow the user to confirm the scene while changing the number of thumbnail images Tp representing the contents of the scene by a more intuitive operation, and thus the scene can be more easily compared to the conventional case. Can be confirmed.

<2. Second Embodiment>
Next, a second embodiment will be described. In the second embodiment, two thumbnail images Tp belonging to different scenes are dragged and superimposed on the moving image list screen Ms so that the two scenes to which they belong can be combined. .

  Note that the configuration of the DVC 100, the configuration of the moving image list screen Ms, the change of the number of thumbnails displayed by pinch-out and pinch-in, and the like are the same as in the first embodiment, and therefore the first embodiment is referred to. Therefore, only scene combination will be described here.

[2-1. Combine scenes]
First, similarly to the first embodiment, when the CPU 101 switches to the reproduction mode, the CPU 101 displays a moving image list screen Ms as shown in FIG. 3 on the liquid crystal display 106.

  Here, as shown in FIG. 18A, when one place on the thumbnail image Tp is continuously touched with a finger for a predetermined time (for example, several seconds), the CPU 101 recognizes the thumbnail image Tp as a dragged thumbnail image Tp. To do. At this time, the CPU 101 highlights, for example, a frame of the thumbnail image Tp as shown in FIG. This allows the user to recognize that the thumbnail image Tp is ready to be dragged.

  Then, when the touch position moves while being touched, the CPU 101 moves the thumbnail image Tp to be dragged in accordance with this movement, as shown in FIG. In this way, the thumbnail image Tp is dragged.

  A copy Tp (c) of the thumbnail image Tp is continuously displayed at the original position of the thumbnail image Tp being dragged. This allows the user to recognize where the original position of the thumbnail image Tp being dragged was.

  Such dragging can be performed simultaneously on two thumbnail images Tp by touching different thumbnail images Tp with two fingers, for example.

  Then, as shown in FIG. 19A, when two fingers touch up in a state where two thumbnail images Tp belonging to different scenes are overlapped by dragging, the two thumbnail images are displayed. Two scenes to which each Tp belongs are combined. Note that the touch-up is a touch operation for releasing the touching finger from the touch panel 104.

  Specifically, the CPU 101 connects two scenes by linking the beginning of the other scene to the end of the scene with the earlier shooting start time of the two scenes to which each of the two thumbnail images Tp belongs. (That is, moving image data).

  Then, the CPU 101 stores a new scene formed by combining the two scenes in the storage medium 112 as a moving image file, and deletes each moving image file of the original two scenes from the storage medium 112. Further, the CPU 101 updates the moving image management file based on the creation and deletion of the moving image file.

  Then, the CPU 101 updates the display content of the thumbnail display area ARp in response to such update of the moving image management file. That is, the CPU 101 causes the thumbnail display area ARp to display the thumbnail image Tp extracted from the combined scene instead of the thumbnail image Tp extracted from each of the original two scenes.

  As a result, as shown in FIG. 19B, in the thumbnail display area ARp, the thumbnail images Tp that have been displayed divided into two scenes are displayed together in one scene. In this way, the CPU 101 is configured to combine two scenes.

  In FIGS. 19A and 19B, the scene 10 from which two thumbnail images Tp are extracted and the scene 11 from which three thumbnail images Tp are extracted are combined. In this example, five thumbnail images Tp are extracted from the scene. In this case, it is assumed that the maximum number n of thumbnail extractions is set to 5 or more.

  Therefore, for example, when the maximum value n of thumbnail extractions is set to 3, even if the scene 10 and the scene 11 are combined, only three thumbnail images Tp are extracted from the new scene. .

[2-2. Scene merge processing procedure]
Next, a processing procedure for combining two scenes (this is also called a scene combining processing procedure) will be described.

  Incidentally, this scene combination processing procedure is also a processing procedure executed by the CPU 101 of the DVC 100 in accordance with a program written in the ROM 102.

  When the CPU 101 displays the moving image list screen Ms, the CPU 101 starts the scene combination processing procedure RT3 shown in FIG. 20, and proceeds to step SP40. In step SP40, the CPU 101 determines whether or not any two locations on the thumbnail image Tp displayed in the thumbnail display area ARp are touched.

  If a negative result is obtained here, the CPU 101 returns to step SP40 at this time. On the other hand, if any two places on the thumbnail image Tp are touched and a positive result is obtained in step SP40 described above, the CPU 101 proceeds to step SP41.

  In step SP41, the CPU 101 determines whether or not the two thumbnail images Tp are touched up while being overlapped by dragging.

  Here, when a negative result is obtained, this means that, for example, the thumbnail image Tp is not dragged, or two thumbnail images Tp are not overlapped. At this time, the CPU 101 proceeds to step SP42, and executes the same processing as steps SP31 to SP33 in the above-described thumbnail display number change processing procedure RT2 (FIG. 16). That is, the CPU 101 determines whether or not pinch-out or pinch-in has been performed, and when determining that it has been performed, the CPU 101 changes the number of thumbnails displayed in accordance with these operation amounts. Thereafter, the CPU 101 returns to step SP40.

  On the other hand, if the two thumbnail images Tp are touched up while being overlapped by dragging, and if a positive result is obtained in step SP41 described above, the CPU 101 proceeds to step SP43.

  In step SP43, the CPU 101 determines whether or not the two superimposed thumbnail images Tp are thumbnail images Tp belonging to different scenes.

  Here, when a negative result is obtained, this means that two superimposed thumbnail images Tp belong to the same scene. At this time, the CPU 101 returns to step SP40.

  On the other hand, if the two thumbnail images Tp that belong to each other belong to different scenes, and if a positive result is obtained in step SP43 described above, the CPU 101 proceeds to step SP44.

  In step SP44, the CPU 101 combines the scenes to which the two superimposed thumbnail images Tp belong to generate a new scene. Then, the CPU 101 extracts the thumbnail image Tp from the new scene and displays it in the thumbnail display area ARp, and then returns to step SP40.

  The CPU 101 repeats the processing from step SP40 to step SP44 while displaying the moving image list screen Ms.

  With such a scene combination processing procedure RT3, the CPU 101 combines the scenes to which the two thumbnail images Tp superimposed by dragging belong to one scene.

  As described above, in the DVC 100 according to the second embodiment, the scene to which each of the two thumbnail images Tp belongs can be performed by an intuitive operation of dragging and overlapping each of the two thumbnail images Tp belonging to different scenes. Can be combined.

  Thus, the DVC 100 can easily combine the two scenes on the moving image list screen Ms that displays the thumbnail images Tp extracted from each scene together for each scene (that is, for each moving image file).

<3. Third Embodiment>
Next, a third embodiment will be described. In the third embodiment, the last thumbnail image Tp of one of the two scenes and the top image Tp (s) of the other scene are dragged and overlapped to belong to each other. Two scenes are combined.

  Note that the configuration of the DVC 100, the configuration of the moving image list screen Ms, the change of the number of thumbnails displayed by pinch-out and pinch-in, and the like are the same as in the first embodiment, and therefore the first embodiment is referred to.

  Further, since the dragging of the thumbnail image Tp is the same as that of the second embodiment, reference is made to the second embodiment. Therefore, only scene combination will be described here.

[3-1. Combine scenes]
Specifically, as shown in FIG. 21A, the last thumbnail image Tp of one of the two scenes and the top image Tp (s) of the other scene are overlaid by dragging. Assume that two fingers are touched up. Then, the CPU 101 combines two scenes to which each of these two thumbnail images Tp belongs.

  Specifically, the CPU 101 connects two scenes (that is, moving image data) by connecting the head of the scene to which the top image Tp (s) is dragged to the end of the scene to which the last thumbnail image Tp is dragged. Join.

  As a result, as shown in FIG. 21B, the thumbnail images Tp that have been divided into two scenes are displayed together in one scene in the thumbnail display area ARp. In this way, the CPU 101 is configured to combine two scenes.

  On the other hand, even when two thumbnail images Tp are overlapped, the condition that one is the last thumbnail image Tp of the scene and the other is the first image Tp (s) of the scene is satisfied. Otherwise, the CPU 101 does not combine scenes. This condition is also called a coupling condition.

  As described above, in the third embodiment, unlike the second embodiment, the last thumbnail image Tp of one scene and the top image Tp (s) of the other scene are overlapped. Only in some cases is it possible to combine two scenes.

[3-2. Scene merge processing procedure]
Next, the scene combination processing procedure will be described. Incidentally, this scene combination processing procedure is also a processing procedure executed by the CPU 101 of the DVC 100 in accordance with a program written in the ROM 102.

  When the CPU 101 displays the moving image list screen Ms, the CPU 101 starts a scene combination processing procedure RT4 shown in FIG. 22 and proceeds to step SP50. In step SP50, the CPU 101 determines whether or not any two places on the thumbnail image Tp displayed in the thumbnail display area ARp are touched.

  If a negative result is obtained here, the CPU 101 returns to step SP50 at this time. On the other hand, if any two places on the thumbnail image Tp are touched, and if a positive result is obtained in step SP50 described above, the CPU 101 proceeds to step SP51.

  In step SP51, the CPU 101 determines whether or not the two thumbnail images Tp are touched up while being overlapped by dragging.

  If a negative result is obtained here, the CPU 101 moves to step SP52, executes the same processing as steps SP31 to SP33 in the above-described thumbnail display number change processing procedure RT2 (FIG. 16), and returns to step SP50. .

  On the other hand, if the two thumbnail images Tp are touched up while being overlapped by dragging, and a positive result is obtained in step SP51 described above, the CPU 101 proceeds to step SP53.

  In step SP53, the CPU 101 determines whether or not each of the two superimposed thumbnail images Tp is the last thumbnail image Tp of one scene and the first image Tp (s) of the other scene. .

  Here, if a negative result is obtained, the two thumbnail images Tp that are superimposed satisfy the combination condition that one is the last thumbnail image Tp of the scene and the other is the first image Tp (s) of the scene. Means no. At this time, the CPU 101 returns to step SP50.

  On the other hand, if the two thumbnail images Tp that are overlapped satisfy the above-described combination condition, and if a positive result is obtained in step SP53 described above, the CPU 101 proceeds to step SP54.

  In step SP54, the CPU 101 combines the scenes to which each of the two superimposed thumbnail images Tp belongs to generate a new scene. Then, the CPU 101 extracts the thumbnail image Tp from the new scene and displays it in the thumbnail display area ARp, and then returns to step SP50.

  The CPU 101 repeats the processing from step SP50 to step SP54 while the moving image list screen Ms is displayed.

  With such a scene combination processing procedure RT4, the CPU 101 combines the scenes to which the two thumbnail images Tp superimposed by dragging belong to one scene.

  As described above, in the DVC 100 according to the third embodiment, only when the last thumbnail image Tp of one scene and the top image Tp (s) of the other scene are overlapped, two scenes are displayed. It comes to be combined.

  Thus, the DVC 100 can combine the two scenes with a more intuitive operation in which the end of one scene is connected to the beginning of the other scene.

<4. Fourth Embodiment>
Next, a fourth embodiment will be described. In the fourth embodiment, at the time of scene combination, not only the beginning of the other scene is connected to the end of one scene but also the two scenes can be partially deleted and combined. .

  Note that the configuration of the DVC 100, the configuration of the moving image list screen Ms, the change of the number of thumbnails displayed by pinch-out and pinch-in, and the like are the same as in the first embodiment, and therefore the first embodiment is referred to.

  Further, since the dragging of the thumbnail image Tp is the same as that of the second embodiment, reference is made to the second embodiment. Therefore, only scene combination will be described here.

[4-1. Combine scenes]
Here, it is assumed that three threshold values of threshold value 1 = 40 seconds, threshold value 2 = 80 seconds, and threshold value 3 = 120 seconds are set. In this case, 1 thumbnail from a scene of 40 seconds or less, 2 from a scene of 40 seconds or more and 80 seconds or less, 3 from a scene of 80 seconds or more and 120 seconds or less, and 4 thumbnails from a scene of 120 seconds or more An image Tp is extracted.

  Here, as shown in FIGS. 23A and 23B, a scene 30 with a shooting start time of 10:00 and a length of 96 seconds, and a shooting start time of 11:00 and a length of 96. Assume that the second scene 31 is combined.

  In this case, the thumbnail extraction points of the scene 30 are set at three locations, the first, 32 seconds later, and 64 seconds later. Therefore, from the scene 30, three images are extracted: the first image Tp (s), the thumbnail image Tp after 32 seconds, and the thumbnail image Tp after 64 seconds.

  Similarly, the thumbnail extraction points of the scene 31 are also three places, the first, 32 seconds later, and 64 seconds later. From this scene 31, the first image Tp (s), the thumbnail image Tp 32 seconds later, and 64 seconds later. Three thumbnail images Tp are extracted.

  Here, as shown in FIG. 23C, the thumbnail image Tp 32 seconds after the scene 30 (second image) and the thumbnail image Tp 32 seconds after the scene 31 (second image) are overlapped by dragging. It is assumed that two fingers are touched up in the pressed state. Then, the CPU 101 combines the scene 30 and the scene 31.

  Specifically, as shown in FIG. 24A, the CPU 101 determines that the thumbnail image Tp after the dragged thumbnail image Tp from the scene 30 whose playback start time is earlier (after 64 seconds in this case). The portion corresponding to the thumbnail image Tp) is deleted.

  Here, the portion corresponding to the thumbnail image Tp indicates a portion from the thumbnail extraction point of the thumbnail image Tp to the next thumbnail extraction point. The portion corresponding to the last thumbnail image Tp is a portion from the thumbnail extraction point of the thumbnail image Tp to the end of the scene.

  Therefore, the CPU 101 deletes the portion from 64 seconds to the end from the scene 30. As a result, a portion from the beginning of the scene 30 to 64 seconds later remains.

  Further, the CPU 101 deletes the portion corresponding to the thumbnail image Tp (in this case, the first image Tp (s)) before the thumbnail extraction point of the dragged thumbnail image Tp from the scene 31 with the later reproduction start time. That is, the CPU 101 deletes the portion from the scene 31 up to 32 seconds after the beginning. As a result, a portion from 32 seconds to 96 seconds after the scene 31 remains.

  Then, the CPU 101 connects the scene 30 and the scene 31 by connecting the head of the remaining portion of the scene 31 to the end of the remaining portion of the scene 30. As a result, as shown in FIG. 24B, the portion of the scene 30 from the beginning to 64 seconds later and the portion of the scene 31 from 32 seconds to the end (96 seconds later) are connected. A scene is possible.

  Then, the CPU 101 stores a new scene formed by combining the two scenes in the storage medium 112 as a moving image file, and deletes each moving image file of the original two scenes from the storage medium 112. Further, the CPU 101 updates the moving image management file based on the creation and deletion of the moving image file.

  Then, the CPU 101 updates the display content of the thumbnail display area ARp in response to such update of the moving image management file. That is, the CPU 101 causes the thumbnail display area ARp to display the thumbnail image Tp extracted from the combined scene instead of the thumbnail image Tp extracted from each of the original two scenes.

  As a result, a thumbnail image Tp extracted from a new 128-second scene formed by combining the scene 30 and the scene 31 is displayed in the thumbnail display area ARp.

  The thumbnail images Tp that are displayed at this time are displayed between two thumbnail images Tp that are overlapped among a total of six thumbnail images that have been extracted and displayed from each of the scenes 30 and 31. Except for the two that were used, the total is 4.

  That is, the thumbnail image Tp after 64 seconds of the scene 30 and the top image Tp of the scene 31 displayed between the thumbnail image Tp after 32 seconds of the scene 30 and the thumbnail image Tp after 32 seconds of the scene 31. It becomes 4 sheets except 2 sheets with (s).

  As a result, two superimposed thumbnail images Tp (thumbnail image Tp 32 seconds after scene 30 and thumbnail image Tp 32 seconds after scene 31) are displayed side by side.

  As described above, when two thumbnail images Tp belonging to different scenes are overlapped, the DVC 100 deletes a portion corresponding to the thumbnail image Tp displayed between the two thumbnail images Tp from the two scenes. To be combined.

[4-2. Scene merge processing procedure]
Next, the scene combination processing procedure will be described. Incidentally, this scene combination processing procedure is also a processing procedure executed by the CPU 101 of the DVC 100 in accordance with a program written in the ROM 102.

  When the CPU 101 displays the moving image list screen Ms, the CPU 101 starts the scene combination processing procedure RT5 shown in FIG. 25, and proceeds to step SP60. In step SP60, the CPU 101 determines whether or not any two places on the thumbnail image Tp displayed in the thumbnail display area ARp are touched.

  If a negative result is obtained here, the CPU 101 returns to step SP60 at this time. On the other hand, if any two places on the thumbnail image Tp are touched, and if a positive result is obtained in step SP60 described above, the CPU 101 proceeds to step SP61.

  In step SP61, the CPU 101 determines whether or not the two thumbnail images Tp are touched up while being overlapped by dragging.

  If a negative result is obtained here, the CPU 101 proceeds to step SP62, executes the same processing as steps SP31 to SP33 in the above-described thumbnail display number change processing procedure RT2 (FIG. 16), and returns to step SP60. .

  On the other hand, if the two thumbnail images Tp are touched up while being overlapped by dragging, and a positive result is obtained in step SP61 described above, the CPU 101 proceeds to step SP63.

  In step SP63, the CPU 101 determines whether or not the two superimposed thumbnail images Tp are thumbnail images Tp belonging to different scenes.

  If a negative result is obtained here, the CPU 101 returns to step SP60 at this time. On the other hand, if a positive result is obtained in step SP63, the CPU 101 proceeds to step SP64.

  In step SP64, the CPU 101 deletes the portion corresponding to the thumbnail image Tp displayed between the two superimposed thumbnail images Tp from the two scenes and combines them. Then, the CPU 101 extracts the thumbnail image Tp from the new scene formed by combining and displays it in the thumbnail display area ARp, and then returns to step SP60.

  The CPU 101 repeats the processing from step SP60 to step SP64 while the moving image list screen Ms is displayed.

  By such a scene combination processing procedure RT5, the CPU 101 combines the scenes to which the two thumbnail images Tp overlapped by dragging belong to one scene.

  As described above, in the DVC 100, a portion corresponding to the thumbnail image Tp displayed between the two superimposed thumbnail images Tp is deleted from the two scenes and combined.

  Thus, the DVC 100 can easily perform editing (also referred to as cut editing) for connecting the desired part of the scene and the desired part on the moving image list screen Ms.

<5. Fifth embodiment>
Next, a fifth embodiment will be described. In the fifth embodiment, a scene can be partially deleted in response to a flick to the thumbnail image Tp. Note that flicking is an operation of lightly touching the touch panel 104 with a finger (or a pen or the like).

  Note that the configuration of the DVC 100, the configuration of the moving image list screen Ms, the change of the number of thumbnails displayed by pinch-out and pinch-in, and the like are the same as in the first embodiment, and therefore the first embodiment is referred to.

[5-1. Partial deletion of scene]
First, similarly to the first embodiment, when the CPU 101 switches to the reproduction mode, the CPU 101 displays a moving image list screen Ms as shown in FIG. 3 on the liquid crystal display 106.

  Here, it is assumed that flicking in the downward direction on the screen is performed simultaneously (or almost simultaneously) on each of the two thumbnail images Tp.

  Then, the CPU 101 extracts a portion corresponding to each of the two thumbnail images Tp and a portion corresponding to the thumbnail image Tp displayed between the two thumbnail images Tp from the scene including these portions. delete.

  Specifically, for example, as shown in FIG. 26 (A), the length is 160 seconds, and the thumbnail extraction points are set at the top, 5 seconds after 64 seconds, 96 seconds and 128 seconds. Assume that there is a scene 40 that is being played.

  Then, as shown in FIG. 26 (B), the thumbnail image Tp 32 seconds after the scene 40 (second image) and the thumbnail image Tp 96 seconds after the scene 40 (fourth image) are flicked. Suppose that

  At this time, as shown in FIG. 26C, the CPU 101 deletes the portion corresponding to the flicked second thumbnail image Tp from the scene 40 (that is, the portion from 32 seconds to 64 seconds later).

  Further, the CPU 101 deletes the portion corresponding to the fourth thumbnail image Tp (the portion from 96 seconds to 128 seconds later) from the scene 40.

  Further, the CPU 101 deletes the portion corresponding to the third thumbnail image Tp displayed between the second and fourth images (the portion from 64 seconds to 96 seconds) from the scene 40.

  As a result, as shown in FIG. 26D, a portion from the beginning of the scene 40 to 32 seconds later and a portion from 128 seconds to the end (160 seconds later) remain.

  Then, the CPU 101 updates the moving image file of the scene 40 according to the partial deletion of the scene 40. Further, the CPU 101 updates the moving image management file based on such updating of the moving image file.

  Then, the CPU 101 updates the display content of the thumbnail display area ARp in response to such update of the moving image management file. That is, the CPU 101 re-extracts the thumbnail images Tp from the partially deleted scene 40 and displays them in the thumbnail display area ARp.

  As a result, in the thumbnail display area ARp, two thumbnail images Tp (first image Tp (s) and thumbnail image Tp after 32 seconds) re-extracted from the scene 40 from 160 seconds to 64 seconds are displayed. The

  As described above, when the two thumbnail images Tp are flicked, the DVC 100 includes a portion corresponding to these and a portion corresponding to the thumbnail image Tp displayed between them as a scene including these portions. It is supposed to be removed from.

[5-2. Partial deletion procedure]
Next, a partial scene deletion processing procedure will be described. Incidentally, this partial deletion processing procedure is also a processing procedure executed by the CPU 101 of the DVC 100 according to the program written in the ROM 102.

  When the CPU 101 displays the moving image list screen Ms, the CPU 101 starts a partial deletion processing procedure RT6 shown in FIG. 27, and proceeds to step SP70. In step SP70, the CPU 101 determines whether or not any two places on the thumbnail image Tp displayed in the thumbnail display area ARp are touched.

  If a negative result is obtained here, the CPU 101 returns to step SP70 at this time. On the other hand, if any two places on the thumbnail image Tp are touched and a positive result is obtained in step SP70 described above, the CPU 101 proceeds to step SP71.

  In step SP71, the CPU 101 determines whether or not the two thumbnail images Tp are flicked.

  Here, when a negative result is obtained, this means that two places are touched but no flick is performed. At this time, the CPU 101 proceeds to step SP72, executes the same processing as steps SP31 to SP33 in the above-described thumbnail display number change processing procedure RT2 (FIG. 16), and returns to step SP70.

  On the other hand, if the two thumbnail images Tp are flicked and a positive result is obtained in step SP71 described above, the CPU 101 proceeds to step SP73.

  In step SP73, the CPU 101 deletes the part corresponding to the two flicked thumbnail images Tp and the part corresponding to the thumbnail image Tp displayed between them from the scene including these parts. Then, the CPU 101 re-extracts the thumbnail image Tp from this partially deleted scene and displays it in the thumbnail display area ARp, and then returns to step SP70.

  The CPU 101 repeats the processing from step SP70 to step SP73 while displaying the moving image list screen Ms.

  With such a partial deletion processing procedure RT6, the CPU 101 performs partial deletion of the scene according to the flick.

  As described above, the DVC 100 deletes the part corresponding to the two flicked thumbnail images Tp and the part corresponding to the thumbnail image Tp displayed between them from the scene including these parts. It has become.

  Thus, the DVC 100 can easily perform editing to delete an arbitrary part of the scene on the moving image list screen Ms.

<6. Sixth Embodiment>
Next, a sixth embodiment will be described. In the sixth embodiment, the contents of an arbitrary scene can be confirmed in more detail on a scene detail window described later.

  Note that the configuration of the DVC 100, the configuration of the moving image list screen Ms, and the like are the same as those in the first embodiment, and therefore, the first embodiment is referred to. Therefore, only the scene detail window will be described here.

  First, similarly to the first embodiment, when the CPU 101 switches to the reproduction mode, the moving image list screen Ms as shown in FIG. 3 is displayed on the liquid crystal display 106.

  Here, it is assumed that the thumbnail image Tp is double-tapped. Note that the double tap is a touch operation in which the same location is touched twice in succession.

  Then, as shown in FIG. 28, the CPU 101 overlaps the moving image list screen Ms with a scene detail window Sw for confirming the details of the scene to which the double-tapped thumbnail image Tp belongs (that is, the designated one scene). Display.

  The scene detail window Sw has a horizontally long rectangular shape, and thumbnail images Tp extracted from one designated scene are displayed side by side in chronological order from the left side. That is, the thumbnail image Tp extracted from only one designated scene is displayed in the scene detail window Sw.

  Further, in this scene detail window Sw, the shooting start time Pt of one designated scene is displayed, and further, each thumbnail extraction point is displayed as an elapsed time from the top in the vicinity of the upper part of each thumbnail image Tp.

  Further, the number of thumbnails displayed in the scene can be changed on the scene detail window Sw. Here, a change in the number of thumbnails displayed on the scene detail window Sw will be described.

  In this scene detail window Sw, the number of thumbnails displayed can be changed by pinching out or pinching in while dragging two thumbnail images Tp.

  Specifically, when the two thumbnail images Tp continue to be touched for a predetermined time, the CPU 101 recognizes these two thumbnail images Tp as the drag target thumbnail images Tp.

  Then, it is assumed that pinch-out or pinch-in is performed as it is, and the interval between the two thumbnail images Tp is changed. Then, the CPU 101 changes the number of thumbnail images Tp displayed between these two thumbnail images Tp according to the change amount of the interval at this time (that is, the amount of pinch-in or pinch-in operation).

  For example, as shown in FIG. 29A, a head image Tp (s) extracted from a scene having a length of 96 seconds, a thumbnail image Tp after 32 seconds, and a thumbnail image Tp after 64 seconds. Assume that three images are displayed in the scene detail window Sw.

  Here, for example, the first image Tp (s) and the thumbnail image Tp after 32 seconds (second image) are pinched out while being dragged, and the amount of operation reaches one horizontal width of the thumbnail image Tp. To do.

  Then, the CPU 101 changes the thumbnail extraction number n between the thumbnail extraction point of the top image Tp (s) and the thumbnail extraction point of the thumbnail image Tp after 32 seconds to the current thumbnail extraction number n + 1.

  That is, the number n of thumbnail extractions between the thumbnail extraction point of the first image Tp (s) and the thumbnail extraction point of the thumbnail image Tp after 32 seconds is changed from “0” to “1”.

  As a result, as shown in FIG. 29C, one thumbnail extraction point is added between the thumbnail extraction point of the top image Tp (s) and the thumbnail extraction point of the thumbnail image Tp after 32 seconds. Then, the CPU 101 newly extracts a thumbnail image Tp from the added thumbnail extraction point (for example, after 16 seconds).

  Thereby, the thumbnail image Tp after 16 seconds is additionally displayed between the head image Tp (s) and the thumbnail image Tp after 32 seconds.

  Similarly, if the amount of pinch-out operation reaches the width of two thumbnail images Tp, two thumbnail images Tp are additionally displayed between the first image Tp (s) and the thumbnail image Tp after 32 seconds. If the number reaches three, three are additionally displayed.

  By doing so, the CPU 101 can make the user check the contents of the portion between the top image Tp (s) and the thumbnail image Tp after 32 seconds in more detail.

  When the first image Tp (s) and the last (64 seconds later) thumbnail image Tp are pinched out, the thumbnail extraction number n of the entire scene is changed in the same manner as in the first embodiment. Is done.

  On the other hand, for example, the first image Tp (s) and the thumbnail image Tp after 64 seconds (third image) are pinched in while being dragged, and the amount of operation reaches the width of one thumbnail image Tp. To do.

  Then, the CPU 101 changes the thumbnail extraction number n between the thumbnail extraction point of the top image Tp (s) and the thumbnail extraction point of the thumbnail image Tp after 64 seconds to the current thumbnail extraction number n-1.

  That is, the number n of thumbnail extractions between the thumbnail extraction point of the first image Tp (s) and the thumbnail extraction point of the thumbnail image Tp after 64 seconds is changed from “1” to “0”.

  As a result, the thumbnail extraction point after 32 seconds between the thumbnail extraction point of the top image Tp (s) and the thumbnail extraction point of the thumbnail image Tp after 64 seconds is deleted.

  As a result, the thumbnail image Tp after 32 seconds displayed between the head image Tp (s) and the thumbnail image Tp after 64 seconds is deleted.

  Thus, in the scene details window Sw, not only the thumbnail extraction number n of the entire scene can be changed, but also the thumbnail extraction number n of an arbitrary part of the scene can be changed.

  As a result, it is possible to increase the number n of thumbnail extractions and increase the number of thumbnail images Tp to be displayed only for portions that are desired to be confirmed in detail.

  Note that such a change in the number of displayed thumbnails is applied only to the scene displayed in the scene detail window Sw, and is not applied to other scenes.

  Also, such a change in the thumbnail extraction number n is applied only when displayed in the scene detail window Sw. When the scene detail window Sw is closed, the original thumbnail extraction number n is restored. It has become.

  The scene detail window Sw is closed by double tapping again.

  When the thumbnail image Tp displayed in the scene detail window Sw is flicked to the right of the screen, the CPU 10 closes the scene detail window Sw and displays the moving image playback window Mp. It is also.

<7. Other embodiments>
[7-1. Other Embodiment 1]
In the first embodiment described above, N threshold values for the scene length are set, and the threshold value n is compared with the scene length to set the number n of thumbnails extracted from the scene. did. Then, based on the thumbnail extraction number n, n thumbnail images Tp are extracted from the scene and displayed.

  For example, a thumbnail image of a frame every predetermined time interval (for example, every 3 minutes) may be extracted from each scene. That is, you may make it set the thumbnail extraction point of a scene for every predetermined time interval.

  Also in this case, when a favorite point is set in the vicinity of the thumbnail extraction point (that is, within the search range H), a thumbnail image of a frame corresponding to the favorite point is extracted instead of the thumbnail extraction point.

  In the first embodiment described above, the top image Tp (s) is extracted with the highest priority. Therefore, even if a favorite point is set near the top thumbnail extraction point, the thumbnail of this favorite point is set. Images are not extracted.

  In addition to this, when a favorite point is set in the vicinity of the first thumbnail extraction point, a thumbnail image (that is, a favorite image) Tp (m) of the favorite point is used instead of the first image Tp (s). You may make it extract. The leading image Tp (s) is registered in advance in the moving image management file as the management information of each file. However, the present invention is not limited to this and is extracted from the scene each time without registration. Also good.

[7-2. Other Embodiment 2]
Further, in the first embodiment described above, when the amount of pinch-out operation reaches one horizontal width of the thumbnail image Tp, the number of thumbnails displayed for each scene is increased by one.

  For example, when the operation amount of the pinch-out reaches 0.8 horizontal width of the thumbnail image Tp, the thumbnail display number may be increased by one. In other words, the relationship between the amount of pinch-out operation and the increase in the number of thumbnails displayed can be freely adjusted.

  Similarly, the relationship between the amount of pinch-in operation and the number of thumbnails displayed can be freely adjusted.

[7-3. Other Embodiment 3]
Furthermore, in the first embodiment described above, the favorite point can be set at an arbitrary point in the scene by pressing the mark button of the operation unit 105 when the scene is shot.

  However, the present invention is not limited to this, and a favorite point may be set at an arbitrary point in the scene by pressing a mark button of the operation unit 105 when the scene is played back.

  Further, a mark deletion button may be provided as an operation unit 105 in the DVC 100 so that the CPU 101 can delete a favorite point that has already been set in response to pressing of the mark deletion button.

  In this case, for example, when a mark deletion button is pressed during reproduction of an arbitrary scene, the CPU 101 may delete the favorite point set in this scene. For example, when the mark deletion button is pressed in a state where the favorite image Tp (m) is selected, the CPU 101 may delete the favorite point corresponding to the favorite image Tp (m).

  In this case, when an arbitrary favorite image Tp (m) is touched, the CPU 101 selects the favorite image Tp (m).

[7-4. Other Embodiment 4]
Further, in the above-described second embodiment, when two thumbnail images Tp belonging to different scenes are touched up in a state where they are overlapped by dragging, the two scenes to which these belong are combined.

  Not limited to this, when one thumbnail image Tp belonging to a certain scene is dragged and touched up with the thumbnail image Tp belonging to another scene, the two scenes to which these belong are combined. You may do it. The same applies to the third and fourth embodiments.

[7-5. Other Embodiment 5]
Furthermore, in the fifth embodiment described above, a portion corresponding to the two flicked thumbnail images Tp and a portion corresponding to the thumbnail image Tp displayed between them are included. Removed from the scene.

  However, the present invention is not limited thereto, and when one thumbnail image Tp is flicked, only a portion corresponding to the thumbnail image Tp may be deleted from the scene to which the thumbnail image Tp belongs.

[7-6. Other Embodiment 6]
Furthermore, in the first to fifth embodiments described above, the number of thumbnails displayed is changed by pinching out or pinching in on the thumbnail image Tp. In addition, the two scenes are joined by dragging and superimposing the two thumbnail images Tp. Further, the scene is reproduced or an arbitrary part of the scene is deleted by flicking the thumbnail image Tp.

  Such an operation is an example, and various other operations can be used to change the number of thumbnails displayed, combine two scenes, play a scene, or delete any part of a scene. May be.

  For example, an arbitrary part of the scene may be deleted according to a flick of the screen upper direction rather than the screen lower direction.

  Further, the DVC 100 may be provided with a zoom lever (TELE / WIDE) as the operation unit 105, and the CPU 101 may change the number of thumbnails displayed according to the operation of the zoom lever.

  In this case, for example, when the zoom lever is operated to the TELE side, for example, the number of thumbnails displayed for each scene is reduced, and when the zoom lever is operated to the WIDE side, the number of thumbnails displayed is increased.

[7-7. Other Embodiment 7]
Furthermore, in the fourth and fifth embodiments described above, the portion corresponding to the thumbnail image Tp is the portion from the thumbnail extraction point of the thumbnail image Tp to the next thumbnail extraction point.

  Not limited to this, a portion corresponding to the thumbnail image Tp is set to be a portion of an equally divided period T / 2 (that is, a portion within the search range H) around the thumbnail extraction point of the thumbnail image Tp. It may be.

  In this case, with respect to the head image Tp (s), the portion from the head to the equal period T / 2 is a corresponding portion. For the last thumbnail image Tp, the part up to the end of the scene is the corresponding part.

[7-8. Other Embodiment 8]
Further, in the first embodiment described above, on the moving image list screen Ms, for each scene, the shooting start time Pt of the scene starting from the top image Tp (s) is displayed near the top of the top image Tp (s). I tried to do it.

  However, the present invention is not limited to this, and the length of the scene to which the thumbnail image Tp belongs and the shooting end time may be displayed for each scene near the upper portion of the thumbnail image Tp extracted from the scene. In this way, the user can recognize the length of the scene more accurately.

  Furthermore, in the first embodiment described above, the leading image Tp (s) is formed with a notch Ch at the upper left corner so that it can be distinguished from other thumbnail images Tp. However, the present invention is not limited to this, and a mark having a shape different from the triangle mark Mk on which a character indicating the head (for example, “S”) is displayed at a corner in the head image Tp (s) or the favorite image Tp (m) is displayed. May be displayed.

  Further, characters and marks other than the triangular mark Mk may be displayed for the favorite image Tp (m).

  Furthermore, a character or mark indicating the tail may be displayed on the last thumbnail image Tp of the thumbnail images Tp extracted from the scene.

[7-9. Other Embodiment 9]
Furthermore, in the first embodiment described above, the number of thumbnails displayed is changed by pinching out or pinching in on the thumbnail image Tp. Further, a reset button as the operation unit 105 may be provided in the DVC 100, and the CPU 101 may return the thumbnail display number to the original number in response to pressing of the reset button. The original number is based on the thumbnail extraction number n set by the extraction number setting processing procedure SRT1 shown in FIG.

  For example, when a gesture operation of drawing a circle with a finger is performed on the moving image list screen Ms, the CPU 101 may return the thumbnail display number to the original number without providing the reset button. .
