A playback control method for controlling a video playback device to play a video stored in a memory, the memory for storing a playback time of each image constituting the video, the playback control method comprising the following steps: a positive image; determining whether the selected images are the same; if the selected images are different, extracting the playing time of the selected image in the memory; determining whether there are still unselected images in the video; If there are still unselected images in the video, select the next pair of adjacent images in the video; if the images in the video are all selected, the video stored in the memory is played according to the extracted playback time. In the above video playback apparatus and its playback control method, the playback unit plays only the video in the extracted time period. Nothing, users don't have to waste time watching images that don't have picture changes, and it's not easy to miss small moves in the video. [Embodiment] As shown in Fig. 1, a video playback device 1 is connected to a memory 2A. The memory 200 is used to store images constituting a video and playback time of each image. The memory 200 can be an sd card, a mobile hard disk, or the like. The video playback device 10 is for playing back video stored in the memory 200. Of course, the memory 2 can also be integrated in the video playback device. 099133208 Form No. A0101 Page 5 / Total 13 Page 0992058065-0 201215140 [0018] [0018] ''Picture Unit 120, Ratio, Input Unit 160 Select Memory 200 The video playback device 100 includes the selection unit 11 The comparison unit 130, the extraction unit, the merge list, and the playback unit 170. The selection unit 丨1〇 is used to place a pair of adjacent images in the video. The scaling unit 12G is for reducing the image of _ according to the needs of the user. The comparing unit 13G is for comparing the scaled image (4) to determine whether the adjacent images are the same 'and generating an extracted signal when the adjacent images are different. [0019] The extracting unit 140 is configured to extract the playing time of the selected image in the memory 2〇〇 in response to the extracted signal. [0020] The merging unit 150 is configured to merge the play times extracted by the extracting unit .140. Thus, adjacent multiple time periods will be merged into one time period' to avoid duplicating the endpoints of adjacent multiple time periods. [0021] The input unit 160 is configured to generate an input signal in response to a user's operation. The input unit 160 may be a button set on the video playback device 100 or a function menu item displayed by the video playback device 1 . [0022] The playback unit 170 is configured to respond to the input ^ generated by the input unit 1 60. The merging unit 150 plays the video stored in the memory 200 at the combined time, that is, only plays the video in the combined time period. 11 users don't waste time watching images that don't change, and it's not easy to miss the small movements in the video. As shown in FIG. 2, a playback control method is used to control a video playback device to play a video. The video can be stored in a memory connected to the video playback device or integrated into the memory within the video playback device.

The above broadcast control method includes the following steps. Step S801, selecting a pair of adjacent images in the video. Step S803, the selected image is scaled according to the user's needs. In step S805, it is determined whether the selected images are the same. If the selected images are not identical, the process proceeds to step S807. If the selected images are the same, it proceeds to step S809. Step S807, extracting the playing time of the selected image in the memory. Step S809, it is determined whether there are still unselected images in the video. If there is still an unselected image in the video, it proceeds to step S811. If the images in the video are all selected, the process proceeds to step S813. In step S811, the next pair of adjacent images in the video is selected, and the flow returns to step S805. In step S813, the extracted play time is merged, so that the adjacent multi-time segments will be merged into one time period, and the end points of the adjacent plurality of time segments can be avoided from being repeatedly recorded. In step S815, it is judged whether or not the input signal is generated. If the input signal is generated, it proceeds to step S817. If the input signal has not been generated, it returns to step S815. In the present embodiment, a button is provided on the video playback device 100, and when the button is pressed, an input signal is generated. In other embodiments, video playback device 100 displays a menu item that is generated when the menu item is selected. In step S817, the video stored in the memory is played according to the combined time. 099133208 Form number Α0101 Page 7/13 page 0992058065-0 201215140, that is, only the video in the combined time period is played. In this way, the user does not need to waste time watching images that have no picture changes, and it is not easy to miss the small movements in the video.
