Abstract:
1. A video playback apparatus that performs processing on an obtained video and plays back the video after the processing, the video playback apparatus comprising: a detection unit configured to detect a size and a position of an image of a person appearing in the video, the size and the position changing over time; a generation unit configured to generate a playback video that is to be played back, in such a way that the image of the person to be shown in the playback video is of a predetermined size, by (i) determining a clipping range for a part of the video in response to a change in the detected position of the image of the person, and (ii) enlarging or reducing a partial video in response to a change in the detected size of the image of the person, the partial video being the part of the video shown in the clipping range; and a playback unit configured to play back the playback video generated by the generation unit, wherein a response time for the determination of the clipping range by the generation unit is longer than a response time for the enlargement or the reduction of the partial video, the video playback apparatus further comprises a person data processing unit configured to perform predetermined processing on the respective changes in the size and the position of the image of the person detected by the detection unit, and generate target information which is information indicating the respective changes in the size and the position of the image of the person after the predetermined processing, wherein the person data processing unit is configured to perform the predetermined processing so that the response time for the determination of the clipping range by the generation unit with respect to the change in the position of the image of the person detected by the detection unit is longer than the response time for the enlargement or the reduction of the partial video with respect to the change in the size of the image of the person detected by the detection unit, and the generation unit is configured to perform the determination of the clipping range and the enlargement or the reduction of the partial video according to the target information generated by the person data processing unit.
