Abstract
(EN)
An image display device comprising a display panel, a barrier panel, and a controller. The controller is configured so as to be able to set a first display region and a second display region in the display panel. The controller is configured so as to be able to set a first transmission region and a second transmission region in the barrier panel. The controller is configured so as to be able to obtain user eye position information. The controller is configured so as to be able to set a reference position on the basis of the eye position information. The controller is configured so as to be able to set divided regions in at least either the display panel or the barrier panel, on the basis of the distance from the reference position. The controller is configured so as to be able to set, to each divided region, at least either: a parallax image pitch indicating the pitch at which the first display region and the second display region are alternately arranged; and a barrier pitch indicating the pitch at which the first transmission region and the second transmission region are alternately arranged.

La présente invention concerne un dispositif d’affichage d’image comprenant un panneau d’affichage, un panneau de barrière et un dispositif de commande. Le dispositif de commande est configuré de façon à pouvoir régler une première région d'affichage et une seconde région d'affichage dans le panneau d'affichage. Le dispositif de commande est configuré de façon à pouvoir régler une première région de transmission et une seconde région de transmission dans le panneau de barrière. Le dispositif de commande est configuré de façon à pouvoir obtenir des informations de position d'oeil d'utilisateur. Le dispositif de commande est configuré de façon à pouvoir régler une position de référence sur la base des informations de position d'oeil. .Le dispositif de commande est configuré de façon à pouvoir régler des régions divisées dans au moins le panneau d'affichage ou le panneau barrière, sur la base de la distance par rapport à la position de référence. Le dispositif de commande est configuré de façon à pouvoir régler, dans chaque région divisée, au moins l'un ou l'autre d'un pas d'image de parallaxe indiquant le pas auquel la première région d'affichage et la seconde région d'affichage sont agencées en alternance; et d'un pas de barrière indiquant le pas auquel la première région de transmission et la seconde région de transmission sont agencées en alternance.
