Abstract:
An adaptive offset filter (60) adds an offset to the pixel value of each pixel forming an input image. The adaptive offset filter (60) refers to offset-type specifying information, sets offset attributes for a subject unit area of the input image, decodes an offset having a bit width corresponding to an offset value range included in the set offset attributes, and adds the offset to the pixel value of each pixel forming the input image.
