Method and apparatus for detecting and displaying a representative image of a shot of short duration in a moving image |
摘要 |
A method and apparatus for displaying a representative image corresponding to a shot of a duration within a specified range included in a plurality of shots of a moving image. The moving image includes a plurality of successive frames each having an image and each shot includes a plurality of the successive frames. In the invention a plurality of shot change points are sequentially detected from the moving image. The shot change points represent points between a pair of frames where images of a preceding shot and images of a succeeding shot have changed. Thereafter a detection is performed to determine whether a duration of a shot between a preceding shot change point and a succeeding shot change point is within the specified range. A representative image corresponding to the shot having a duration within the specified range is displayed along with duration time information representing the duration of the shot. A reduced image from the shot can be displayed as the representative image and the number of detected shots having a duration within the specified range can be reduced according to preset conditions.
