Abstract
L'invention concerne un appareil de télécinéma prévu pour fonctionner selon le standard de télévision 625/50. Les images consécutives du film sont balayées par un rayon lumineux de manière que plusieurs détecteurs optoélectroniques transforment l'information optique modulée en un signal électrique vidéo. Des circuits de traitement vidéo transforment ces informations dans deux champs de télévision entrelacés. Cet appareil est caractérisé en ce que le film est entraîné de manière continue et le balayage est réalisé en mode séquentiel à une fréquence linéaire supérieure à la fréquence standard. L'amplitude de déviation du balayage vertical est plus grande que si l'image était balayée en mode séquentiel à la fréquence standard. Application au télécinéma couleur.
