For this reason, there is a demand for a display of characters in a multiple manner, as required by a user. Also, a problem arises in the prior art display method using the fringe forming processing or the reversal processing in that a limitation of the character patterns to be displayed exists, and thus a desired character display cannot be realized. Therefore, there is a need for the development of an apparatus, method, and application apparatus by which the fringe forming processing and the reversal processing are properly handled and a multiple display of characters is realized.

  • the selectible outputting of the character display data, the fringe formed character display data, the reversed character display data, or the fringe formed reversed character display data can be carried out.
  • the reversal processing for replacing between the display color and the background color of the character display pattern or the fringe formed character display pattern is carried out, or after the reversal processing of the character display pattern, the fringe forming and interpolatible processing of the reversibly processed character display pattern is carried out.
  • the producible processing of the peripheral region formed, reversed, fringe formed character display patten can be carried out. Accordingly, it is possible to clearly and definitely recognize the cursor display in the computer picture processing or the characters displayed on the TV picture plane, without being affected by the background color or the like.
  • the picture display means, the picture synthesizing means, and the display control means are used. Accordingly, the display processing of characters and pictures by the fringe forming color based on the background color of the display plane of the display device or the like can be executed. Accordingly, a multiple display of characters is realized and the demands of the user can be satisfied. Also, a picture synthesis processing apparatus such as an on-screen display controller or the like for a high quality character display processing can be realized.

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.
