Title
(EN) SYSTEMS AND METHODS FOR REDUCING IMAGE ARTEFACTS IN BINOCULAR DISPLAYS
(FR) SYSTÈMES ET PROCÉDÉS DE RÉDUCTION D'ARTEFACTS D'IMAGE DANS DES AFFICHAGES BINOCULAIRE
Abstract
(EN)
Aspects of embodiments pertain to a method for reducing a subjective visual artefact when displaying binocular overlapping images to a user of a binocular display system, the method comprising generating, by an image display unit comprising a plurality of pixels elements, right and left-eye source images; projecting the right and left-eye source images via corresponding left and right viewing optics to its user such that the user perceives partially overlapping left and right-hand observation images; reducing, a perception of a subjective visual artefact in the perceived right and/or left-hand observation images by modifying one or more pixel and/or image parameters values relating to the left and/or right-hand source images.
(FR)
Des aspects de modes de réalisation de l'invention concernent un procédé de réduction d'un artefact visuel subjectif lors de l'affichage d'images de chevauchement binoculaire à un utilisateur d'un système d'affichage binoculaire, le procédé comprenant la génération, par une unité d'affichage d'image comprenant une pluralité d'éléments de pixels, d'images sources d'œil droit et gauche; la projection des images sources d'œil droit et gauche par l'intermédiaire d'une optique de visualisation gauche et droite correspondante à son utilisateur de telle sorte que l'utilisateur perçoive partiellement des images d'observation gauche et droite se chevauchant partiellement; la réduction d'une perception d'un artefact visuel subjectif dans les images d'observation droite et/ou gauche perçues par la modification d'une ou plusieurs valeurs de paramètres de pixel et/ou d'image concernant les images sources gauche et/ou droite.
