Title
(EN) IMAGE DISPLAY DEVICE AND ELECTRONIC APPARATUS
(FR) DISPOSITIF D'AFFICHAGE D'IMAGES ET APPAREIL ÉLECTRONIQUE
(JA) 画像表示装置及び電子機器
Abstract
(EN)
This image display device comprises: a first optical unit that refracts light from a display element so as to change the direction of advancement along an optical path; a second optical unit upon which the light refracted by the first optical unit falls incident; and a control unit that, when a display region of the display element is divided into a plurality of regions along a scanning direction, controls the distance between the first optical unit and the second optical unit depending on the plurality of regions, thereby establishing a state in which the timing for changing the direction of advancement along the optical path is different depending on the plurality of regions.
(FR)
La présente invention concerne un dispositif d'affichage d'image comprenant : une première unité optique qui réfracte la lumière provenant d'un élément d'affichage de façon à changer la direction d'avancement le long d'un trajet optique; une seconde unité optique sur laquelle la lumière réfractée par la première unité optique tombe en incidence; et une unité de commande qui, lorsqu'une région d'affichage de l'élément d'affichage est divisée en une pluralité de régions le long d'une direction de balayage, commande la distance entre la première unité optique et la seconde unité optique en fonction de la pluralité de régions, ce qui permet d'établir un état dans lequel la synchronisation pour changer la direction d'avancement le long du trajet optique est différente en fonction de la pluralité de régions.
