Abstract
Un dispositif de visualisation pour télévision en couleurs à canons multiples comportant, pour chaque canon, un système de réglage de niveau de réference du courant de faisceau identique où la disposition d'un niveau de référence dans le signal vidéo et une tension de réglage des canons électroniques sont périodiquement décalées afin de faire coïncider, en dehors des périodes de mesure pour le système de réglage, le niveau de référence dans le signal vidéo et le point de coupure de chacun des canons électroniques à l'effet d'obtenir une reproduction des couleurs exactes à faible luminosité. Application : récepteur téléviseur couleurs.
