Abstract
MACHINE DE TELECINEMA COMPORTANT UN DETECTEUR TRANSISTORISE 22 DEVANT LEQUEL DU FILM EST ENTRAINE A UNE VITESSE CONSTANTE. POUR COMPENSER LES DIFFERENCES ENTRE LES RAPPORTS D'UTILISATION RESPECTIFS D'IMAGE DE FILM ET DE TRAME DE TELEVISION, C'EST-A-DIRE DES DIFFERENCES DANS LA PROPORTION DE L'ETENDUE DU BALAYAGE VERTICAL QUI EST OCCUPEE PAR DE L'INFORMATION ACTIVE ETOU DES DIFFERENCES ENTRE LA FREQUENCE D'IMAGE DU FILM ET LA FREQUENCE DE TRAME DE TELEVISION, UN SIGNAL DE SORTIE EST ENGENDRE SOUS LA FORME D'UN PREMIER SIGNAL DE TELEVISION SEQUENTIEL DE TYPE NON STANDARD, QUI EST CONVERTI ELECTRONIQUEMENT EN UN SECOND SIGNAL STANDARD DU TYPE A BALAYAGE ENTRELACE. PAR EXEMPLE, POUR OBTENIR UN SIGNAL 62550 A PARTIR DE FILM DE 35MM, UN SIGNAL SEQUENTIEL 72350 EST TOUT D'ABORD ENGENDRE, TANDIS QU'A PARTIR DE FILM DE 8MM, UN SIGNAL SEQUENTIEL 62533 13 EST TOUT D'ABORD ENGENDRE. APPLICATION NOTAMMENT AUX SCENES TOURNEES SUR LE VIF.
