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

摘要

An image filter (100) for calculating a pixel value of target pixel in an output image from a pixel value of each of a pixel or pixels belonging to a filter area in an input image by using a filter coefficient vector V, is configured to include a filter coefficient vector changing section (120) for changing the filter coefficient vector V according to at least either where the target area is in the input image, or where the target pixel is in the output image.
