Abstract
L'invention concerne un appareil de télécinéma à spot mobile dans lequel le film de cinéma est entraîné à une vitesse d'images qui ne correspond pas exactement à la moitié de la fréquence image de télévision. Les images consécutives du film sont balayées optiquement par un rayon lumineux et l'information image est transformée en un signal vidéo électrique par des détecteurs opto-électroniques. Cet appareil est caracterisé en ce que chaque image de film est balayée une seule fois. Des circuits de traitement vidéo 10, 11, 12 comprennent un agencement de stockage 12, dans lequel l'information d'image est enregistrée. Un signal de synchronisation commande, pour chaque vitesse d'image, le mouvement du film 8 et l'agencement de stockage 12. Application à la visualisation de films de cinémas sur tube vidéo.
