Abstract
Système de traitement pour des images de télévision. Un système selon l'invention est un générateur d'effets spéciaux de télévision comportant une mémoire d'image vidéo 12 et une mémoire de cache vidéo 22. L'unité de traitement à coefficients est utilisée pour chaque mémoire et comporte un circuit de commande variable 26 pour modifier les dimensions de l'image vidéo et de l'image du cache. Le genérateur d'effets spéciaux peut être utilisé avec un mélangeur, l'information traitée de cache étant utilisée comme signal de manipulation pour le mélangeur.
