Abstract

Système pour réaliser l'uniformité de brillance dans un dispositif d'affichage d'images comportant une pluralité de faisceaux électroniques en réponse à un signal de brillance d'image d'entrée, caractérisé en ce qu'il comporte des moyens pour détecter le courant électronique de chaque faisceau électronique, des moyens pour emmagasiner l'information de courant de faisceau detecté et des moyens pour modifier le signal de brillance avec l'information emmagasinée afin de compenser les courants de faisceau électronique non uniformes.
