Abstract
A compression noise reduction apparatus includes a peripheral pixel state determination module, a filter strength determination module, and a deringing processing module. The peripheral pixel state determination module determines a state of a flat area and an edge area at a periphery of a filtering target pixel in decoded image. The filter strength determination module determines a filter strength to be used in filter processing in accordance with the state of the flat area and the edge area. The deringing processing module performs deringing processing using the determined filter strength.
