摘要

PROBLEM TO BE SOLVED: To detect a scene change point while securely improving the convenience of a user independently of the type of videos.;SOLUTION: The change point is extracted from the candidates of the scene change points so that mutual time internals become appropriate. Information showing the genre ('sports' and 'interview', for example') of the video is set at the time of reserving recording, for example. A picture where a difference (the difference of a value based on a DCT coefficient in the case of MPEG, for example) with a candidate picture just before exceeds a threshold which is set in accordance with the genre of the video is specified from the candidate picture ( an I picture in the case of MPEG, for example) of the scene change point included in the picture constituting the video is specified. The appearing time of the picture is detected as the scene change point. Thus, the scene change points whose intervals are appropriate with respect to any type of the videos are obtained.;COPYRIGHT: (C)2002,JPO
