Abstract

Dans le système d'affichage décrit, où des caractères et des figures sont affichés sur un écran, les opérations du processus de formation des contours et du processus d'inversion sont combinées indépendamment du simple processus de sélection, de façon à diversifier les formes d'affichage des caractères. L'unité de commande d'affichage des images comprend un organe d'affichage d'image (2) qui émet un ou plusieurs types de données d'affichage de caractères sur la base de signaux de commande externes, un premier organe de formation de contours (111) qui émet des données d'affichage de caractères avec amélioration des contours sur la base des données d'affichage de caractères. Un premier organe de sélection (131) qui émet sélectivement les données d'affichage de caractères ou les données d'affichage de caractères avec amélioration des contours, un premier organe d'inversion (121) qui émet des données d'affichage de caractères inversés ou des données d'affichage de caractères inversés avec amélioration des contours sur la base des données d'affichage de caractères ou des données d'affichage de caractères avec amélioration des contours, ainsi qu'un organe de commande (15) qui commande l'entrée et la sortie de l'organe d'affichage d'images, du premier organe avec amélioration des contours, du premier organe de sélection et du premier organe d'inversion.
