Abstract

L'invention a trait à la télévision. Elle a pour objet un circuit de compensation thermique de variations de courant d'obscurité d'organes de prises de vue de préférence munis d'une surface sensible en matériau semi-conducteurs dans des installations de génération d'images de télévision, lequel circuit est contenu dans un circuit vidéo. L'entrée de tension de niveau d'un étage de restitution de niveau et de limitation 4 est reliée à la sortie d'un circuit de réglage 2, et à une entrée du circuit de réglage 2 est reliée une unité de surveillance 1 et à l'autre entrée du circuit de réglage 2, un étage de réglage de niveau 3. Application : compensation thermique de variations de courant d'obscurité de caméras de télévision.
