Title (EN) COLOUR SATURATION CONTROL CIRCUIT
(FR) CIRCUIT DE REGULATION DE LA SATURATION DES COULEURS
Abstract: front page image
(EN)A video signal colour saturation control circuit comprising: means (1, 2, 3) for receiving RGB video signals; means (4, 7, 9, 5, 8, 10, 11, 12, 14) for deriving from the received RGB signals luminance and colour difference signals and for variably controlling the level of the colour difference signals so as to control the colour saturation; and means (13, 15, 16) for deriving from the controlled colour difference signals RGB signals which are thereby saturation controlled.
(FR)Circuit de régulation de la saturation des couleurs de signaux vidéo comportant: des mécanismes (1, 2, 3) pour recevoir des signaux vidéo rouges, verts et bleus, des mécanismes (4, 7, 9, 5, 8, 10, 11, 12, 14) pour dériver des signaux rouges, verts et bleus reçus des signaux de luminance et de couleurs différentes et pour réguler de manière variable le niveau des signaux de couleurs différentes afin de réguler la saturation des couleurs; et des mécanismes (13, 15, 16) pour dériver des signaux régulés de couleurs différentes des signaux rouges, verts et bleus dont la saturation est ainsi régulée.
