Abstract

　画像を矩形に分割し、動き補償に基づく動画像圧縮データを復号して画像に展開して画像メモリに格納するデコーダは、圧縮データを復号して係数データと動きベクトルデータとを記憶部に格納する符号データ復号部と、記憶部から読み出した係数データに基づいて逆量子化処理及び逆周波数変換処理を行い矩形の残差画像を生成する係数データ処理部と、記憶部から読み出した動きベクトルデータに基づいて画像メモリから参照画像を読み出して矩形の予測画像を生成する動きベクトルデータ処理部と、残差画像と予測画像とを加算して復号画像を生成し画像メモリに格納する動き補償部と、デコーダ内の動作タイミングを制御する制御部とを備える。動きベクトルデータ処理部は、少なくとも２つ以上の矩形に対する予測画像を記憶する予測画像バッファと、前記少なくとも２つ以上の矩形に対する予測画像が生成されたことを予測画像レディ信号で制御部に通知する予測画像生成通知部とを有し、制御部は予測画像レディ信号に応答して動作タイミングを制御する。
