Abstract

L'invention concerne un procédé de compression d'informations d'images animées et un système associé destiné à comprimer, à un taux de compression élevé et à grande vitesse, des données, de façon que des informations images puissent être codées en prédiction et que la qualité d'image soit améliorée. Dans un mode de réalisation, l'image dans une trame est divisée en blocs avant la compression intertrame, et chaque bloc est approché d'un plan unique (ou remplacé par ce dernier) défini par trois éléments des pixels dans le bloc. Dans un deuxième mode de réalisation, le pixel d'une image originale est comparé à celui de son image décompressée-compressée, les informations relatives à la différence de chaque élément de pixel sont émises, et la taille de bloc la plus petite est appliquée si un élément de pixel conduisant à une différence supérieure au paramètre (seuil) P existe, de façon à effectuer une compression intertrame. Dans un troisième mode de réalisation, des blocs I, produits par la division spatiale d'une image, sont dispersés le long de l'axe temporel entre les trames de telle façon qu'aucun bloc I ne soit inséré à une position de bloc dans une trame mise à jour lorsque la différence entre les trames supérieure au paramètre (seuil) P apparaît au cours d'une période désignée.
