Abstract
L'INVENTION CONCERNE UN APPAREIL, DANS UN SYSTEME DE TRAITEMENT D'UN SIGNAL VIDEO AYANT DES INTERVALLES RECURRENTS D'IMAGE ET D'EFFACEMENT. SELON L'INVENTION L'APPAREIL COMPORTE UN MOYEN 38, 39, 40A DETECTANT LA GRANDEUR DE COURANT CONDUIT PAR L'ELECTRODE D'UN TUBE-IMAGE; UN MOYEN 52, 54, 61, 63 DERIVANT UNE TENSION DE REGLAGE PENDANT LES INTERVALLES D'EFFACEMENT, INDIQUANT DES ECARTS DU COURANT D'ELECTRODE PAR RAPPORT A UN NIVEAU SOUHAITE; ET UN MOYEN 28 APPLIQUANT LA TENSION DE REGLAGE A UN CIRCUIT DE SORTIE POUR REDUIRE LA DIFFERENCE ENTRE LE COURANT D'EFFACEMENT DETECTE ET LE COURANT SOUHAITE. L'INVENTION S'APPLIQUE NOTAMMENT AUX TELEVISEURS EN COULEURS.
