Abstract

　予測効率と符号化効率とを最適化することができる映像符号化方法及び映像符号化装置を提供する。 　映像データに含まれる入力画像を構成する整数画素間を補間する小数画素の画素値を算出するための適応的補間フィルタを用いて、小数画素精度の動き補償を行うことで、前記映像データを符号化する映像符号化装置（１００）であって、適応的補間フィルタのフィルタ特性を所定の処理単位ごとに設定し、設定したフィルタ特性を有する適応的補間フィルタの複数のフィルタ係数を、整数画素との相対的な小数画素の位置ごとに決定し、決定した複数のフィルタ係数を有する適応的補間フィルタを入力画像に適用することで、小数画素精度の動き補償を行う動き補償予測部（１６０）と、動き補償により生成された予測画像と、入力画像とを減算することで予測誤差を生成する減算器（１１０）と、予測誤差を符号化するエントロピー符号化部（１９０）とを備える。
