Abstract

La présente invention a pour objectif de permettre à un moniteur (moyen d'affichage) classique d'être utilisé comme un moniteur pour des images stéréoscopiques. Pour atteindre cet objectif, la présente invention se rapporte à l'affichage, sur un moniteur (9), au moyen d'un module de commande (8a) ayant la fonction d'un moyen de contrôle d'affichage, d'une image pour un œil droit au moyen d'une combinaison de pixels R et de pixels G parmi les sous-pixels (SP, Sub-Pixel) du moniteur (9). L'invention se rapporte d'autre part à l'affichage, sur le moniteur (9), d'une image pour un œil gauche au moyen de pixels B. Enfin, l'invention se rapporte à l'affichage de l'image pour un œil droit et de l'image pour un œil gauche en même temps et sur le même écran. La solution technique de la présente invention permet à une image stéréoscopique d'être vue par un utilisateur qui porte des lunettes de couleur. Ces lunettes de couleur sont munies : d'un filtre de couleur pour un œil droit (qui transmet seulement des pixels R et des pixels G) pour voir l'image pour un œil droit ; et d'un filtre de couleur pour un œil gauche (qui transmet seulement des pixels B) pour voir l'image pour un œil gauche.
