Abstract

Procédé destiné à la conversion de fréquences d'image et dans lequel des suites de signaux, dont chacune correspond à une seule image ou une image partielle d'une suite d'images, sont stockées avec une fréquence de mise en mémoire préétablie et sont ensuite à nouveau transformées en une image complète ou partielle. Les suites de signaux mises en mémoire sont transformées en images complètes ou partielles avec une fréquence de reproduction différente de la fréquence de mise en mémoire. L'invention est applicable notamment à des vidéodisques et à la reproduction répétée, notamment au ralenti, de scènes de spectacles télévisés.A method for converting frame rates and in which signal sequences, each of which corresponds to a single image or a partial image of a sequence of images, are stored with a preset memory rate and are thereafter again transformed into a full or partial image. The sequences of signals stored in memory are transformed into complete or partial images with a reproduction frequency different from the storage frequency. The invention is applicable in particular to videodiscs and to the repeated reproduction, in particular in slow motion, of scenes from television shows.
