Abstract

L'invention concerne un système de visualisation d'images stéréo, notamment un système de visualisation d'images stéréo associé à un écran d'affichage. Le système est principalement constitué d'un miroir stéréo permettant de visualiser l'écran d'affichage et d'un système d'affichage. Le miroir permettant de visualiser l'écran d'affichage est composé de deux groupes de réflecteurs. Les lignes de visée des deux yeux d'un utilisateur atteignent les deux parties d'une paire d'images stéréo distinctes respectivement situées à gauche et à droite de l'écran d'affichage suite à une double réflexion. Pour combiner l'affichage de la paire d'images stéréo, l'invention affiche simultanément les images distinctes de gauche et de droite respectives de la paire d'images stéréo au moyen d'un procédé utilisant deux fenêtres d'affichage d'images indépendantes, l'une à gauche et l'autre à droite. Lors d'un formatage, d'un zoom avant, d'un zoom arrière, d'une compression latérale et d'autres opérations de traitement des images, les côtés gauche et droit agissent de façon concordante afin de conserver la symétrie des deux parties de la paire d'images stéréo.
