Abstract
A coding distortion removal method for removing coding distortion in an image which was has been divided in to a plurality of macroblocks. The method operates under the following conditions such that: (i) a size of a pixel in a motion compensation block is smaller than a size of a pixel in said macroblock; (ii) a size of a pixel in a motion compensation block is larger than a size of a pixel in a coding unit; and (iii) a pixel difference between two adjacent motion compensation blocks located inside the macroblock is zero. The method disables the coding distortion removal at a boundary between blocks located inside each of the two adjacent motion compensation blocks, and enables the coding distortion removal at a boundary between the two adjacent motion compensation blocks.
