画像符号化装置、画像復号装置、画像符号化方法及び画像復号方法
Document Type and Number:
Japanese Patent JP5503747
Kind Code:
B2
Abstract:
When carrying out an intra-frame prediction process to generate an intra prediction image by using an already-encoded image signal in a frame, an intra prediction part 4 selects a filter from one or more filters which are prepared in advance according to the states of various parameters associated with the encoding of a target block to be filtered, and carries out a filtering process on a prediction image by using the filter. As a result, prediction errors which occur locally can be reduced, and the image quality can be improved.
