摘要: An adaptive filter includes: an edge direction detection section which discriminates directionality of input image in each a plurality unit regions constituting the image; region classification classifies into one groups accordance with to predetermined belongs, having been discriminated by section; and process calculates pixel value output use coefficient group optimized for including belongs.
