Abstract

L'invention concerne des ensembles de visualisation d'images. Une représentation codée comprimée d'une image est conservée dans une mémoire 2 et est décodée afin de commander un dispositif 1 de visualisation du type moniteur de télévision. Les données comprimées comprennent des codes de transition qui sont décodés par une unité logique 24 et qui définissent la couleur de chaque élément d'un couple d'éléments d'image de l'image à visualiser, et des codes de longueur de course qui sont décodés par une unité logique 25, de sorte qu'il est obtenu la visualisation d'un segment formé d'un nombre pair d'éléments d'image ayant une longueur qui dépend du code de longueur et qui présente la même couleur que l'élément d'image qui précède le segment L'invention s'applique à la visualisation de données graphiques.
