OFFSET DECODING DEVICE, OFFSET ENCODING DEVICE, IMAGE FILTER DEVICE, AND DATA STRUCTURE

摘要

An adaptive offset filter (60) adds an offset to each pixel value in an input image, references adaptive offset-type designation information, sets the offset attributes in a target unit region in the input image, decodes an offset having a bit width corresponding to an offset value region included in the offset attributes thus set, and adds the offset to each pixel value in the input image.
