Abstract

　プリレコード機能をもつ画像符号化装置であって、映像信号を符号化することでクローズドＧＯＰ又はオープンＧＯＰを生成する符号化部（１１）と、符号化部（１１）で生成された少なくとも１個のＧＯＰを先入れ先出し方式で記憶するバッファ部（１４）と、撮影の開始及び終了の指示を受け付けるユーザＩ／Ｆ部（１２ａ）と、ユーザＩ／Ｆ部（１２ａ）が撮影開始指示を受け付ける前に、非記録状態を確保したうえで符号化部（１１）に符号化を開始させ継続させることでクローズドＧＯＰを含むＧＯＰ列を生成させ、ユーザＩ／Ｆ部（１２ａ）が撮影開始指示を受け付けると、非記録状態から記録状態に切り替えるとともに、符号化部（１１）がオープンＧＯＰだけからなるＧＯＰ列を生成するように符号化部（１１）を制御する記録制御部（１２ｂ）とを備える。
