Abstract

　画像処理装置は、予め設定された複数のレベル値で平滑化された複数の中間平滑化画像を保持し、外部から受け付けた動画像のＮ番目のフレーム画像を縮小処理して縮小画像を生成し、生成された縮小画像に対して、予め設定された複数のレベル値で平滑化処理を実施して複数の中間平滑化画像を生成し、中間平滑化画像記憶部に格納し、Ｎ＋１番目以降のフレームの平滑化画像を生成する場合に、中間平滑化画像記憶部により記憶されたＮ番目のフレームの複数の中間平滑化画像を一つまたは複数取得し、取得されたＮ番目のフレームの中間平滑化画像と外部から受け付けた動画像のＮ＋１番目以降のフレームとを合成して平滑化画像を生成する。
