Abstract
An image encoding and decoding apparatus includes an image encoder for encoding an input image and an image decoder for decoding a variable length coded signal. The image encoder includes a coding unit, a first decoding unit, a first coding distortion removing unit, a first storage unit, and a variable length coding unit. The image decoder includes a variable length decoding unit, a second coding distortion removing unit, and a second storage unit. In the encoding and decoding apparatus, a block size of a motion compensation block is smaller than a block size of the macroblock, a block size of a motion compensation block is larger than a block size of a transform block, and a coded motion compensation error of each of two adjacent motion compensation blocks located inside the same macroblock is zero.
