Abstract
A scene-change detector is disclosed which detects a scene-change of a moving image composed of a plurality of frames. In the apparatus, a moving image is encoded based on the correlation between frames or inside a frame. The energy of an estimation error between frames in the case of encoding is operated by image elements. The energy is totaled by frames, and when the totaled value is larger than a specified value, a signal expressing a scene-change is output.
