Abstract

Abstract Translated from French Dans un système dans lequel on dispose de plusieurs images le dispositif selon l'invention permet de gérer les recouvrements d'images en mettant en oeuvre un mécanisme selon lequel des points de transition sont définis durant le balayage. En ces points de transition le mode d'affichage change. La position horizontale de ces points et la nature du changement d'affichage sont contenus dans un registre spécial (13). Un comparateur d'abscisses (12) compare en permanence l'abscisse courante et l'abscisse indiquée dans le registre (13) et après qu'une identité d'abscisse est été trouvée et un nouveau mode de recouvrement mis en place, le mot suivant du registre (13) est pris en compte. Des moyens (5, 8) permettent de recharger le contenu du registre (13) pendant les retours de ligne de balayage. In a system in which there are several images, the device according to the invention makes it possible to manage the overlapping of images by implementing a mechanism according to which transition points are defined during the scanning. The display mode changes at these transition points. The horizontal position of these points and the nature of the display change are contained in a special register (13). An abscissa comparator (12) constantly compares the current abscissa and the abscissa indicated in the register (13) and after an abscissa identity has been found and a new method of recovery implemented, the word next in the register (13) is taken into account. Means (5, 8) make it possible to reload the content of the register (13) during the scan line returns.
