摘要

A variable length encoding unit 13 variable-length-encodes an index indicating a classification method of carrying out a class classification on each coding block having a largest size, the classification method being determined by a loop filter unit 11, and also variable-length-encodes a parameter about an offset value for each class determined for each coding block having the largest size on the basis of a binarization process using a truncated unary code.
