Abstract

　複数のプロセッサを用いて映像信号処理を行う映像信号処理装置において、動きベクトルを精度良く検出できるようにする。入力映像信号から動きベクトルを検出する動きベクトル検出部（１２１ａ，１２１ｂ）と、検出された動きベクトルの情報を格納するベクトルメモリ（１３）と、入力映像信号をｎ個（ｎは２以上の整数）の領域に分割し、ベクトルメモリ（１３）に格納された動きベクトルの情報を用いて、前記各領域の映像信号を分担処理するフレーム補間処理回路（１２３ａ，１２３ｂ）と、フレーム補間処理回路（１２３ａ，１２３ｂ）による処理結果を合成して出力映像信号を生成する画面合成部（１３）とを備えた映像信号処理装置である。動きベクトル検出部（１２１ａ，１２１ｂ）は、入力映像信号を完全に２分割して得られる領域を含みかつ当該領域よりも広い領域を対象として動きベクトルを検出する。
