Abstract:
(EN) This image signal processing device is provided with a luminance correction circuit which multiplies image signals of consecutive M (M is two or more) frames by weighting factors individually set for frames of respective ranks among the M frames, and adds and averages the results thereof to thereby generate a corrected image signal of a frame of a predetermined rank among the M frames, wherein the value of a weighing factor set for the frame of the predetermined rank is maximum among the values of the weighting factors individually set for the frames of respective ranks among the M frames.
(FR) La présente invention concerne un dispositif de traitement de signal d'image qui est pourvu d'un circuit de correction de luminance qui multiplie des signaux d'image de M (M est égal à deux ou plus) trames consécutives par des facteurs de pondération déterminés de façon individuelle pour des trames de rangs respectifs parmi les M trames, et ajoute et calcule la moyenne de leurs résultats afin de générer, de ce fait, un signal d'image corrigé d'une trame d'un rang prédéterminé parmi les M trames, la valeur d'un facteur de pondération déterminé pour la trame du rang prédéterminé étant maximale parmi les valeurs des facteurs de pondération déterminés de façon individuelle pour les trames de rangs respectifs parmi les M trames.
(JA) この映像信号処理装置は、連続するM(Mは複数)個のフレームの映像信号に対して、M個のフレーム中の各順位のフレームに対して個別に設定された重み係数を掛け、それらの結果を加算平均して、M個のフレーム中で所定順位のフレームの補正映像信号を生成する輝度補正回路を具備し、M個のフレーム中の各順位のフレームに対して個別に設定された重み係数の値のうち、所定順位のフレームに対して設定された重み係数の値が最大とされる。
