Abstract
【解決手段】予測ユニットのイントラ予測モードを誘導し、変換サイズ情報を利用して現在ブロックのサイズを決定し、前記イントラ予測モードに応じて現在ブロックの予測ブロックを生成し、前記イントラ予測モードに応じて現在ブロックの残差ブロックを生成し、予測ブロックと残差ブロックを利用して現在ブロックの復元ブロックを生成する。予測ブロックと残差ブロックのサイズは、変換ユニットのサイズ情報と同じである。したがって、イントラ予測の距離が短くなって、原本ブロックと類似の予測ブロックを生成することができて残差ブロックの符号化量が減少される。また、隣接イントラ予測モードに応じてMPMを適応的に生成することによってイントラ予測モードを送信するためのシグナリングビット数を減少させることができる。
