Abstract

　動き補償型のフレームレート変換（ＦＲＣ）処理に起因する、動き量の大きい動画像の画質劣化を防止する。画像表示装置は、入力画像信号のフレーム間に動き補償処理を施した画像信号を内挿することにより入力画像信号のフレーム数を変換するＦＲＣ部１０、入力画像信号のフレーム間における動き量が所定値より大きいかどうかを判定する動き量判定部１４、制御部１５を備える。ＦＲＣ部１０は、入力画像信号のフレーム間で動きベクトルを検出する動きベクトル検出部１１ｅ、該動きベクトル情報に基づいてフレーム間に内挿ベクトルを割り付ける内挿ベクトル評価部１１ｆ、該内挿ベクトルから内挿フレームを生成する内挿フレーム生成部１２ｄを備える。入力画像信号のフレーム間における動き量が所定値より大きい場合、制御部１５は、動きベクトル検出部１１ｅで検出された動きベクトルを０ベクトルにすることにより、ＦＲＣ部１０の動き補償処理を無効化する。
