摘要

PPROBLEM TO BE SOLVED: To simply perform alignment of scenes which are desired to be compared of a standard video and a reference video to facilitate comparison of a plurality of videos. PSOLUTION: A spatiotemporal image generation part 12 generates spatiotemporal images of the standard video and the reference video for comparison and playback, and a video presentation part 15 displays them. When a standard point to be noticed in the spatiotemporal image of the standard video and a reference point corresponding to the standard point in the spatiotemporal image of the reference video are instructed, display positions are adjusted so that the positions of the standard point and the reference point match to each other to present the spatiotemporal images. Otherwise, the standard point is synchronized with the reference point to play back and output the standard video and the reference video. Otherwise, a reference point corresponding to the standard point is automatically detected. PCOPYRIGHT: (C)2011,JPO&INPIT
