PROBLEM TO BE SOLVED: To select a frame in which the motion of an object in a video easy to recognize and no camera shaking is present in order to create a representative image from the video in a video database system, a video indexing means or a digital video editing system. ;SOLUTION: An image change amount in a video block is calculated by an image change amount calculating means 111, and a frame in which the image change amount is minimum is calculated by an image change amount minimum frame calculating means 112. The frame in which the image change amount becomes minimum is found to detect an image having a high possibility of a characteristic attitude to become a node of the motion when positively moving a figure or an animal. Then, with the found frame in which the image change amount becomes minimum as a reference, a representative image candidate selecting means 113 selects candidates of the representative image in the video block.;COPYRIGHT: (C)2004,JPO
