Abstract

L'invention concerne un dispositif de correction de vitesse de balayage horizontal de tubes à rayons cathodiques. Des valeurs de correction de la vitesse de balayage horizontal sont mémorisées dans une mémoire pour un petit nombre de lignes d'échantillonnage réparties parmi les lignes horizontales d'une trame. Ces valeurs de correction sont lues par un circuit de lecture et sont interpolées en fonction de la position verticale de la ligne balayée de manière à obtenir des signaux de correction qui sont appliqués au dispositif de déviation horizontale du tube. L'invention s'applique notamment à des récepteurs de télévision en couleurs à positionnement de faisceau.
