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

摘要

PROBLEM TO BE SOLVED: To actualize high filter effects while actualizing a large filter application area.SOLUTION: An adaptive offset filter 60 of a moving image decoding device 1 includes: an offset setting part 63 which derives the number of a plurality of offsets to be selected, and selects an offset to be added to a pixel value out of the derived number of offsets for each pixel value; and an adaptive filter part 62 which adds the offset that the offset setting part 63 has selected to the pixel value.
