ABSTRACT:
A moving image signal coding apparatus and moving image signal coding method dividing one frame of the moving image signal into a plurality of areas which may possibly overlap each other and refreshing the areas at different periods corresponding to an independent non-overlapped range at the circumferential portion of the frame and to an overlapped range at the central portion. Further, a specific area in the frame can be encoded by selectively using inter-frame prediction coding and intra-frame prediction coding.
