Abstract

L’invention concerne un procédé de génération d’image pour un système d’affichage sur un support de projection transparent. Le procédé vise à supprimer les effets négatifs de l’image double formée par réflexion sur la surface externe du support de projection qui vient se superposer à l’image principale formée par réflexion sur la surface interne dudit support. L’écran sur lequel est générée l’image qui est projetée sur le support de projection est découpé en un ensemble de bandes de cellules parallèles les unes aux autres. Les cellules de l’écran sont configurées de sorte que toutes les cellules d’une bande sont éteintes pour une bande sur deux. La largeur d’une bande est prédéterminée de sorte que l’image double d’une bande qui n’est pas éteinte est contiguë à l’image principale de ladite bande. L’image double et l’image principale de l’image générée se complètent alors pour former une image finale avec une bonne qualité visuelle. Figure pour l’abrégé : Fig. 2The invention relates to an image generation method for a display system on a transparent projection support. The method aims to eliminate the negative effects of the double image formed by reflection on the external surface of the projection support which is superimposed on the main image formed by reflection on the internal surface of said support. The screen on which the image is generated which is projected on the projection support is cut into a set of strips of cells parallel to each other. The screen cells are configured so that all cells in a band are off for every other band. The width of a strip is predetermined so that the dual image of a strip that is not extinguished is contiguous with the main image of said strip. The double image and the main image of the generated image then complement each other to form a final image with good visual quality. Figure for abstract: Fig. 2
