CODING DISTORTION REMOVAL METHOD, MOVING PICTURE CODING METHOD, MOVING PICTURE DECODING METHOD, AND APPARATUS FOR REALIZING THE SAME, PROGRAM

摘要

When a compressed video signal is reproduced, a mosaic-shaped block noise is generated. This block noise is removed. However, if block noise is removed by the deblock filter from all the blocks, the load on the deblock filter becomes too large. This load can be reduced by performing block filtering only when it is decided that the coding distortion removal is required.
