<P>PROBLEM TO BE SOLVED: To decrease blocking artifacts in video encoding wherein motion compensation is performed. <P>SOLUTION: In an image decoding method, it is determined whether deblock filtering is performed on each border between adjacent blocks in a reference image for a luminance channel (Y) and a chrominance channel (U, V), respectively. Here, it is evaluated whether motion vectors of one of the luminance channel and chrominance channel are similar to each other between adjacent blocks, and it is evaluated whether the motion vectors point the same reference image; when the motion vectors are not similar to each other or when the motion vectors do not point the same reference image, it is determined that deblock filtering is performed on the border of the luminance channel and the border of the chrominance channel, but when the motion vectors are similar to each other and when they point the same reference image, it is determined that the debelock filtering is not performed on the border of the luminance channel and the border of the chrominance channel. <P>COPYRIGHT: (C)2010,JPO&INPIT |
