Abstract

La présente invention concerne un dispositif d'affichage d'image stéréoscopique destiné à la correction de la vision, qui délivre en sortie une image stéréoscopique divisée en une image d'œil gauche et une image d'œil droit, de telle sorte que l'image observée par l'œil pour lequel la vision doit être récupérée est clairement délivrée en sortie en tant qu'image d'origine et la qualité de l'image observée par l'autre œil est diminuée, ce qui permet de corriger la vision naturellement pendant qu'un utilisateur/une utilisatrice visualise l'image stéréoscopique avec ses deux yeux. À cette fin, un dispositif d'affichage d'image stéréoscopique destiné à la correction de la vision comprend une unité d'affichage (3), et une unité de traitement d'image (2) pour permettre à une image d'être affichée sur l'unité d'affichage (3) en étant séparée en une image d'œil gauche et une image d'œil droit, le dispositif comprenant en outre : une unité d'entrée de touches (20) permettant de sélectionner la direction soit de l'œil gauche soit de l'œil droit ; et une unité de conversion de qualité d'image (10) permettant de sélectionner soit une image d'œil gauche soit une image d'œil droit correspondant à la direction de l'œil sélectionnée par l'unité d'entrée de touches (20), et de diminuer la qualité de l'image sélectionnée.
