MOVING IMAGE CODING METHOD, MOVING IMAGE CODER AND MOVING IMAGE DECODER

摘要

PROBLEM TO BE SOLVED: To facilitate setting of an area in response to a characteristic of an image by enhancing a degree of freedom of an area shape in the case of dividing an image into a plurality of areas and coding them. SOLUTION: The moving image coder has an area division section 1, a coding section 7, and a memory 9 that is used to predict motion compensation. The area division section 1 has a division processing section and an integral processing section. The division processing section divides an input image based on a reference relating to the propriety of division. The integral processing section integrates areas close to each other based on the reference relating to the propriety of integration. Then each area is coded. The integral processing diversifies the shape of the area.
