ABSTRACT:
Plural representative points are set in a predetermined arrangement in a frame, and the representative points thus arranged are linked to each other to partition the frame into plural segments. Further, additive representative points are adaptively added in segments, excluding the boundary lines between the segments. Accordingly, the effect of the addition of the additive representative points is limited to the interior of the segment concerned, and thus can be prevented from extending to adjacent segments. Therefore, adaptive processing which is independent on a segment basis can be achieved.
