図1は、本発明に係る実施の形態1の動画像符号化装置の構成を示すブロック図である。図19における従来の動画像符号化装置の構成を示すブロック図と同じ動作をするユニットおよび同じ動作のデータは同じ記号を付し、説明を省略する。なお、以下に説明する各実施の形態の動画像符号化装置および動画像復号化装置では、2枚の参照ピクチャを用いて画素補間により予測画像を生成する方法(複数参照ピクチャ補間予測)、任意の1枚のピクチャに含まれるブロックをそのまま予測画像とする方法、および画面内予測により予測画像を生成する方法などの予測方法を、ブロック単位で切り替えることが可能である。
図3は、本発明に係る実施の形態2の動画像復号化装置のブロック図である。図22における従来の動画像復号化装置の構成を示すブロック図と同じ動作をするユニットおよび同じ動作のデータは同じ記号を付し、説明を省略する。図22と異なる点はデフォルト参照ピクチャ番号バッファ402が追加された点である。
図4は、本発明に係る実施の形態3の動画像符号化装置のブロックである。なお、図1における実施の形態1の動画像符号化装置のブロック図と同じ動作をするユニットおよび同じ動作のデータは同じ記号を付し、説明を省略する。
図9は、本発明に係る実施の形態4の動画像復号化装置のブロック図である。なお、図3における実施の形態2の動画像復号化装置のブロック図と同じ動作をするユニットおよび同じ動作のデータは同じ記号を付し、説明を省略する。
本実施の形態では、符号化対象ピクチャより表示順情報が前のピクチャのみを参照して符号化を行う場合におけるダイレクトモードによる符号化について説明する。
MV2=MV01×(TRD3/TRD2) … (式B)
MV2=−MV01×(TRD3/TRD2) … (式D)
上記H.264では、複数参照ピクチャ補間予測を含むピクチャのスキップモードは、ダイレクトモードによるピクチャ間予測の残差符号化データが0の場合を示す。これに対し、本実施の形態の動画像符号化装置、動画像復号化装置では、スキップモードに使用する予測方法を、マルチフレームバッファの符号化済ピクチャの内で符号化対象ピクチャの表示順情報に最も近い参照ピクチャからのピクチャ間予測とする。
さらに、上記各実施の形態で示した動画像符号化方法または動画像復号化方法の構成を実現するためのプログラムを、フレキシブルディスク等の記憶媒体に記録するようにすることにより、上記各実施の形態で示した処理を、独立したコンピュータシステムにおいて簡単に実施することが可能となる。
