Apparatus, method, and computer-readable storage medium for decoding movie image data

摘要

A selector selects one of a standard parameter corresponding to a filter strength contained in input movie image data and an original parameter originally set at the decoding side as a filter parameter to be used. A screen-display filter performs deblocking filtering using the filter parameter selected by the selector on decoded movie image data. A post-filter performs deblocking filtering using the standard parameter and stores the obtained decoded image data in a memory to allow it to be used in inter-frame compensation.
