Abstract

a. Caméra de télévision en couleur en technique état solide. b. Caméra caractérisée par un premier filtre en peigne destiné à traiter le premier signal de couleur, un second filtre en peigne destiné à traiter le second et le troisième signal de couleur ainsi qu'un circuit de mélange de signaux pour faire la synthèse d'au moins une partie d'un signal de luminance en mélangeant les signaux de sortie du premier filtre en peigne et du second filtre en peigne.
