Abstract
'invention est constituée par une méthode et un appareil de conversion d'images servant à a) stocker une première trame d'image dans une première mémoire, b) stocker une deuxième trame d'image dans une deuxième mémoire, c) lire les contenus de la première et de la deuxième mémoire, d) afficher simultanément sur un écran le premier et le deuxième champ d'image sous la forme d'une image complète et e) tout en effectuant la lecture, à stocker dans une troisième mémoire une troisième trame d'image. La première, la deuxième et la troisième mémoire servent de tampons à images à organisation de bloc mémoire 3 x 3. Pour les trames d'image numérotées 1, 2, 3, 4, 5...n.., le système de l'invention lit les champs d'image deux à la fois dans l'ordre prédéterminé suivant : 1 et 2, 2 et 3, 3 et 4, 4 et 5, ... (n - 1) et n, n et (n + 1). Une longueur de trame à haute définition est choisie plus longue ou plus courte qu'une période de trame de télévision. La différence de phase entre les deux est mesurée et un circuit modifie l'ordre de lecture prédéterminé afin qu'une mémoire à trame dont le contenu doit être lu ne sera pas sollicitée simultanément pour stocker la trame de télévision suivante.
