Abstract

L'INVENTION CONCERNE UN APPAREIL DE PRISE DE VUES ELECTRONIQUE DU TYPE COMPORTANT PLUSIEURS UNITES ELEMENTAIRES D'IMAGES CONSTITUEES CHACUNE D'UN ELEMENT PHOTOSENSIBLE ET D'UN CIRCUIT DE CONTROLE ELECTRIQUEMENT COMMANDE, UN CIRCUIT DE BALAYAGE FOURNISSANT DES IMPULSIONS SEQUENTIELLES AUX CIRCUITS DE CONTROLE, ET UN CIRCUIT DE SORTIE PRODUISANT UN SIGNAL VIDEO. LE CIRCUIT DE SORTIE COMPORTE UN AMPLIFICATEUR 10 A COMMANDE DE GAIN POSSEDANT UN TRANSISTOR D'ENTREE 11 QUI RECOIT LES CHARGES PRODUITES PAR LES UNITES ELEMENTAIRES D'IMAGE COMME COURANT D'ENTREE I, ET UN TRANSISTOR DE SORTIE 14 QUI PRODUIT UN COURANT DE SORTIE AMPLIFIE I, ET UN ELEMENT AJUSTABLE 12 ET 13 QUI AJUSTE SELECTIVEMENT LE GAIN EN FONCTION D'UN SIGNAL DE COMMANDE I QUI LUI EST IMPLIQUE.
