Abstract
Disclosed is a moving picture compression apparatus for performing intra-frame or inter-frame compression every block in frames in a moving picture, which comprises: means for detecting scene change in a moving picture; means for generating code containing information on components in a transformed domain's range gradually extending as the picture advances for a block in a new scene portion of a frame at the scene change detection during plural frames from the frame at the scene change detection, wherein the information is obtained by compressing the block in the new scene portion with the intra-frame compression process in the first frame from the scene change detection, and the information is obtained by compressing the block in the new scene portion with the inter-frame compression process in the second and following frames from the scene change detection.
