Abstract

L'invention concerne un appareil pour produire des signaux de télévision à partir d'un film cinématographique. Cet appareil comprend des moyens pour balayer le film horizontalement à partir d'une station de balayage, pendant que celui-ci défile verticalement devant ladite station. Il est caractérisé en ce qu'il comprend des moyens 18, 25, 29, 31, 32 pour régler la fréquence de balayage horizontal afin de s'adapter à des films de différentes dimensions et à différentes vitesses d'entraînement, tout en exécutant un nombre prédéterminé de balayages horizontaux sur chaque image du film cinématographique, et des moyens 12, 13, 14, 15, 16 pour produire à partir des signaux de balayage de lignes, un certain nombre de trames de télévision à une frequence prédéterminée. Application à la transformation d'images de films cinématographiques, en images de télévision, notamment en couleurs.
