The information relating to the obtained orthogonal transformation coefficient 14 is subjected to proper limit at a correction quantity control section 10, and the orthogonal transformation coefficient subjected to limit is subjected to inverse orthogonal transformation by an inverse orthogonal transformation section 11. The information 15 relating to the entire in-block correction value is related to a picture including block distortion being an output of the inverse orthogonal transformation section 7 at an output correction section 12. Thus, the output picture whose block distortion is reduced is obtained and then the picture quality is improved.
