MOTION COMPENSATION APPARATUS FOR IMPROVING A BLOCKING EFFECT

摘要

PROBLEM TO BE SOLVED: To eliminate blocking phenomenon by dividing a search block into a center area and other peripheral parts and generating an optimum motion vector using a motion vector about peripheral parts. SOLUTION: A motion detector 200 receives a present frame signal and the previous frame signal, detects a motion vector of the present frame with a block matching method and stores it in a memory 210. An area formation block 213 divides a search block which consists of 16×16 pixels into a center area of 12×12 pixels and an edge and corner areas other than the center area, and sends area information indicating position of each area to the optimum motion vector deciding block 216. The optimum motion vector deciding block 216 generates the optimum motion vector from a motion vector of the present frame and a motion vector of the search block adjacent to the other and sends it to a motion compensator 219. In the edge and corner areas, the mean value of the motion vector of adjacent search block on the basis of the area information is regarded as the optimum motion vector.
