(Embodiment 1)
A video signal reproduction apparatus according to Embodiment 1 will be described with reference to FIGS.

  FIG. 1 is an explanatory diagram of screen output of the video signal reproduction apparatus, FIG. 2 is a button layout on the operation panel of the video signal reproduction apparatus, and FIG. 3 is a block diagram of the video signal reproduction apparatus.

  First, the basic operation of the thumbnail screen display of the video signal playback device will be described.

  In the following example, there are currently 12 reproducible moving image data in the recording medium, and the 12th thumbnail image is selected when the user performs the thumbnail screen display operation.

  When the video signal reproduction apparatus is instructed by the user to display a list of moving image data recorded on the recording medium 301, the thumbnail screen display unit (thumbnail screen display means) 306 displays the moving image recorded in the recording medium 301. The number of data is acquired from the media information management unit 305. In the present embodiment, there are twelve. In addition, the reproduction information management unit 307 acquires information indicating what number thumbnail image is selected. In the present embodiment, it is the 12th.

  The thumbnail screen display unit 306 arranges icons 113, 114, 115, and 116 indicating various types of information other than thumbnail images at predetermined positions in the output image memory of the video signal input / output processing unit 303.

  Each icon indicates the following items.

  The icon 113 indicates that the playback mode is set.

  The icon 114 acquires from the media information management unit 305 and the reproduction information management unit 307 the number of moving image data and the thumbnail image of which moving image data is selected, and displays based on that information.

  An icon 115 indicates the remaining battery level.

  An icon 116 indicates an explanation related to button operation on the operation panel.

  When the thumbnail screen display unit 306 has placed the icons 113, 114, 115, and 116 indicating various types of information at predetermined positions in the output image memory of the video signal input / output processing unit 303, the thumbnail information is acquired by the media information management unit 305. A thumbnail image corresponding to the moving image data to be displayed is determined from the number of moving image data and the number of thumbnail images that can be displayed. In the present embodiment, the number of moving image data is 12, and the number of thumbnail images that can be displayed is 12, so that thumbnail images corresponding to all the first to twelfth moving image data are displayed.

  The thumbnail screen display unit 306 instructs the video signal processing unit 302 to generate a thumbnail image corresponding to the first moving image data. The video signal processing unit 302 reads still image data (still image data generated or previously recorded from the corresponding moving image data) from the recording medium 301, and generates a thumbnail image.

  The type of thumbnail image to be generated is determined by the first thumbnail image designating unit (first thumbnail image designating unit) 308 and the second thumbnail image designating unit (second thumbnail image designating unit) 309. The first thumbnail image specifying unit 308 uses the representative image of the moving image data as a thumbnail image, and the second thumbnail image specifying unit 309 is based on the resume information stored in the resume information storage unit (resume information storage unit) 310. The position image is a thumbnail image. The thumbnail image designating unit (thumbnail image designating unit) 311 determines which of the first thumbnail image designating unit 308 and the second thumbnail image designating unit 309 should generate the thumbnail image. The details of generating thumbnail images based on the first thumbnail image specifying unit 308 and the second thumbnail image specifying unit 309 will be described later.

  The thumbnail screen display unit 306 displays the thumbnail image generated by the video signal processing unit 302 corresponding to the first moving image data in the output image memory of the video signal input / output processing unit 303 corresponding to the position 101 in FIG. Arrange at a predetermined position.

  Similarly, the thumbnail screen display unit 306 displays thumbnail images corresponding to the second to twelfth moving image data in the predetermined output image memory of the video signal input / output processing unit 303 corresponding to positions 102 to 112 in FIG. Place in position. Then, based on a predetermined position of the output image memory of the video signal input / output processing unit 303 corresponding to the positions 101 to 112, the display / external output 304 displays the thumbnail image.

  Since the reproduction information management unit 307 acquires information that the 12th thumbnail image is selected, the currently selected thumbnail image is surrounded by a thick frame line or the like. Highlights so that it can be easily recognized.

  The above is the basic operation when the user gives an instruction to display the thumbnail screen of the video signal playback apparatus.

  In this state, when the button 205 on the operation panel is pressed, the reproduction of the twelfth moving image data is started. Further, when the thumbnail display screen is displayed, if a button 201 to 204 on the operation panel is pressed, the thumbnail image to be selected can be changed. The button 201 moves to the upper thumbnail image, the button 202 moves to the lower thumbnail image, the button 203 moves to the left thumbnail image, and the button 204 moves to the right thumbnail image. Also, the thick frame line highlighting performed on the thumbnail image selected at this time is also moved. These buttons 201 to 204 serve as thumbnail image selection means.

  The above is the basic operation in which the user from the thumbnail screen display state reproduces the desired moving image data.

  Hereinafter, an example of a thumbnail image selection operation at the time of displaying a thumbnail screen when the resume function of the video signal reproduction device is ON will be described. The resume function (resume function means) is a function for resuming reproduction based on the resume information stored in the resume information storage unit 310. When this function is used, it is provided in the video signal reproducing apparatus. The resume function switch is turned on, and is turned off when the resume function is not used.

  FIGS. 4 and 5 show an example of switching from the representative image to the resume position image (reproduction resume position image) when the corresponding moving image data storing the resume information is selected. Resume information is stored in the corresponding video data. The screen output difference when the first thumbnail image 101 is selected (FIG. 4) and the twelfth thumbnail image 112 is selected (FIG. 5) is shown.

  FIG. 6 is a flowchart when selecting a thumbnail image. Here, the symbol i indicates a thumbnail counter on the thumbnail screen to be processed, and the symbol N indicates the number of thumbnails to be displayed on the thumbnail screen. In the present embodiment, since 12 thumbnails are displayed on the thumbnail screen, the symbol i is a value from 0 to 11, and the symbol N is 12.

  First, when the first thumbnail image 101 is selected, the process proceeds to step S11 and step S12 in FIG. 6, where 0 is input to i and 12 is input to N, and the resume function is turned on in step S13. It is determined whether or not. At this time, since the resume function is ON, the process branches to step S14. In step S14, the moving image data currently set to resume is the twelfth moving image data, which is different from the corresponding moving image data of the selected thumbnail image, and branches to step S17. The thumbnail image designation unit 311 makes the determination in step S14. In steps S17 and S18, the first thumbnail designation unit 308 displays the representative image as a thumbnail image. In the present embodiment, this is repeated for the first to twelfth moving image data based on the determination in step S17. That is, at this time, all thumbnail images from 1 to 12 are representative images by the first thumbnail designating unit 308 of the corresponding moving image data. If the resume function is OFF in step S13, the process proceeds to steps S17 and S18. At this time, all thumbnail images from 1 to 12 are represented by the first thumbnail designation unit 308 of the corresponding moving image data. It becomes.

  The representative image by the first thumbnail specifying unit 308 is generated as follows, for example. It is generated from the image in the moving image data based on the resume information set in advance by the user. It is generated from the start position of video data or other fixed positions. Use still images recorded separately from video data. A still image generated and recorded in advance from a position specified by the user in the moving image data is used. A still image generated and recorded in advance from the start position of the moving image data or another fixed position is used. It is generated by any one or a combination of the above.

  Next, the button 204 on the operation panel is pressed three times and the button 202 is pressed twice to select the twelfth thumbnail image. In this case, the process proceeds to step S11, step S12, step S13, and step S14 in FIG. In step S14, the moving image data currently set to resume is the twelfth moving image data corresponding to the selected thumbnail image, and the process branches to step S15.

  Based on the determination in step S15, the determination of whether or not it is the resume information setting moving image in step S16 is repeated for the first to twelfth moving image data. Since the moving image for which resume information is set is the twelfth, for the first to eleventh moving image data for which no resume information is set, the first thumbnail designation unit 308 in step S19 performs a representative image of the corresponding moving image data. Is displayed as a thumbnail image, and the 12th moving image data for which resume information is set is displayed by generating a resume position image in the moving image data as a thumbnail image by the second thumbnail designating unit 309 in step S20. That is, in this case, unlike the case where the first thumbnail image is selected, only the twelfth thumbnail image is not a representative image by the first thumbnail designation unit 308. The thumbnail image designation unit 311 makes the determinations in steps S14, S15, and S16.

  According to the video signal reproducing device configured as described above, when moving the thumbnail image to be selected, it is possible to determine which thumbnail image has the resume information of the moving image data corresponding thereto, and the resume information is set. When the thumbnail image of the moving image data is selected, the image data at the resume position is displayed, which makes it easy for the user to use the resume function.

  7 to 14 show modifications of the first embodiment. It is assumed that resume information is stored in the 12th corresponding moving image data.

  7 and 8 show the mark “R” 701 as identification information displayed on the 12th thumbnail image of the corresponding moving image data in which resume information is set, and the first thumbnail image 101 is selected. This shows the difference in screen output when the 12th thumbnail image 112 is selected (FIG. 8) from the current state (FIG. 7).

  The identification information may be a mark other than “R” or a colored frame on the screen.

  9 and 10 show the time information 901 of the resume position on the twelfth thumbnail image of the corresponding moving image data in which the resume information is set, and the state where the first thumbnail image 101 is selected. FIG. 9 shows the difference in screen output when the twelfth thumbnail image 112 is selected (FIG. 10).

  FIGS. 11 and 12 show the mark “R” 701 displayed on the twelfth thumbnail image of the corresponding moving image data for which resume information is set, and the first thumbnail image 101 is selected ( 11), when the 12th thumbnail image 112 is selected (FIG. 12), the time information of the resume position is added to the 12th thumbnail image of the moving image data in addition to the mark “R” 701. 901 is displayed.

  FIGS. 13 and 14 show the mark “R” 701 displayed on the 12th thumbnail image of the corresponding moving image data for which resume information is set, and the time information 1301 of the resume position at a place other than the thumbnail image. A difference in screen output when the first thumbnail image 101 is selected (FIG. 13) to the state where the twelfth thumbnail image 112 is selected (FIG. 14) is shown. In the state of FIG. 13, the resume position time information 1301 is displayed on the right side only for the length (00:10:00) of the moving image data of the scene 1 in the case of the scene 1 in which the resume information is not set. On the left side, there is no set time, that is, (00:00:00) is displayed because playback starts from the beginning. Also. In the state of FIG. 14, the length of the moving image data of the scene 12 is displayed on the right side, and in addition, the time (00:05:00) of the resume position is displayed on the left side.

  The mark “R” 701 may not be displayed on the thumbnail image, and only the resume position time information 1301 may be displayed at a place other than the thumbnail image. The resume position time information 1301 may display the resume position time (00:05:00) only when the thumbnail image 112 is selected.

  According to the above modified example, when moving the thumbnail image to be selected, it becomes easier to determine which thumbnail image is associated with the resume information of the moving image data.

  In the above explanation, one resume information has been set. However, the number of resume information that can be set is not limited to one. It becomes easy.

  For example, as shown in FIG. 15, resume information is stored in the fourth and twelfth corresponding moving image data, and on the fourth and twelfth thumbnail images of the corresponding moving image data for which resume information is set, A mark “R” 701 is displayed. The display of the mark “R” 701 is merely an example, and the display is simply switched to the resume position image as shown in FIGS. 4 and 5, or the time information of the resume position is displayed as shown in FIGS. It may be.

  When the first thumbnail image 101 is selected (FIG. 15) and the fourth thumbnail image 104 is selected (FIG. 16), the fourth thumbnail image 104 is resumed from the representative image. When the screen is switched to the position image and the twelfth thumbnail image 112 is selected (FIG. 17), the twelfth thumbnail image 112 is switched from the representative image to the resume position image.

(Embodiment 2)
A video signal reproduction apparatus according to Embodiment 2 will be described with reference to FIGS.

  In the first embodiment, only when the thumbnail image of the corresponding moving image data for which resume information is set is selected, the second thumbnail designating unit 309 performs the process of switching to the image data at the resume position. 2, when the thumbnail display screen is displayed, the thumbnail image of the corresponding moving image data for which the resume position information is set is always displayed as the thumbnail image by the second thumbnail designation unit 309. It is characterized by that.

  The screen output of the video signal playback apparatus, the button arrangement on the operation panel, and the block configuration of the video signal playback apparatus in the second embodiment are the same as those shown in FIGS.

  FIGS. 18 and 19 are examples when the corresponding moving image data in which the resume information is stored is selected. At this time, the resume information is stored in the twelfth corresponding moving image data. The screen output difference when the first thumbnail image 101 is selected (FIG. 18) and the twelfth thumbnail image 112 is selected (FIG. 19) is shown.

  FIG. 20 is a flowchart when selecting a thumbnail image. The same parts as those in the example shown in FIG. The difference from FIG. 6 is that when the resume function is ON in step S13, the process proceeds to step S15 and step S16. In step S15 and step S16, the moving image for which resume information is set is the twelfth, so the first to eleventh thumbnail images are displayed as representative images of the corresponding moving image data by the first thumbnail designation unit 308 in step S19. Display as thumbnail images. The twelfth thumbnail image for which resume information is set is generated and displayed as a thumbnail image of the resume position image in the moving image data by the second thumbnail designation unit 309 in step S20. The thumbnail image designation unit 311 makes the determination in steps S15 and S16.

  According to the video signal reproducing device configured as described above, even when a thumbnail image is not selected in the thumbnail screen display, it is possible to determine which thumbnail image has the resume information of the moving image data corresponding thereto. Since the image data at the resume position is displayed, it is easy for the user to use the resume function.

  21 and 22 show a modification of the second embodiment. It is assumed that resume information is stored in the 12th corresponding moving image data.

  FIGS. 21 and 22 show the mark “R” 701 as identification information displayed on the 12th thumbnail image of the corresponding moving image data for which resume information is set. The first thumbnail image 101 is selected. This shows the difference in screen output when the 12th thumbnail image 112 is selected (FIG. 22) from the current state (FIG. 21).

  The display of the mark “R” 701 is merely an example, and identification information other than the mark “R” may be displayed, or time information on the resume position may be displayed.

  The present invention can be applied to a video signal reproducing apparatus and a video signal recording / reproducing apparatus that use a randomly accessible medium such as a digital video camera or a digital video recorder.
