Patent
CA 2114256
A video circuit provided with corrective control data generating means which generates respective control data for correcting and controlling the brightness and/or saturation of the picture displayed on a display unit in accordance with the average brightness level of the luminance signal separated from the video signal. The brightness and/or saturation of the picture are thus corrected and controlled on the basis of the corrective control data.
L'invention est un circuit vidéo doté d'un dispositif générateur de données de commande de correction qui produit des données de commande particulières pour corriger et commander la luminosité et/ou la saturation de l'image affichée sur une unité d'affichage selon le niveau de luminosité moyen du signal de luminance extrait du signal vidéo. La luminosité et/ou la saturation de l'image sont donc corrigées et commandées au moyen des données de commande de correction.
