Title (EN) IMAGE DISPLAY DEVICE AND PROJECTION OPTICAL SYSTEM
(FR) DISPOSITIF D’AFFICHAGE D’IMAGE ET SYSTÈME OPTIQUE DE PROJECTION
(JA) 画像表示装置及び投射光学系
Abstract:
(EN) According to one embodiment of the present technology, an image display device is provided with a light source, an image generation unit, and a projection optical system. The image generation unit generates image light by modulating a luminous flux emitted from the light source. The projection optical system has: a first lens group, which is disposed on the optical axis of the image light thus generated, and which has first refractive power; a second lens group, which is disposed on the optical axis, and which has second refractive power; a first moving mechanism that moves the first lens group; and a second moving mechanism that moves the second lens group corresponding to the first refractive power, the second refractive power, and the move of the first lens group.
(FR) Selon un mode de réalisation de la présente invention, un dispositif d’affichage d’image est équipé d’une source de lumière, d’une unité de génération d’images et d’un système optique de projection. L’unité de génération d’images génère une lumière d’image par modulation d’un flux lumineux émis par la source de lumière. Le système optique de projection a : un premier groupe de lentilles, qui est disposé sur l’axe optique de la lumière d’image ainsi générée et qui a une première puissance de réfraction ; un second groupe de lentilles, qui est disposé sur l’axe optique et qui a une seconde puissance de réfraction ; un premier mécanisme de déplacement qui déplace le premier groupe de lentilles ; et un second mécanisme de déplacement qui déplace le second groupe de lentilles par rapport à la première puissance de réfraction, à la seconde puissance de réfraction et au déplacement du premier groupe de lentilles.
(JA) 本技術の一形態に係る画像表示装置は、光源と、画像生成部と、投射光学系とを具備する。前記画像生成部は、前記光源からの光束を変調して画像光を生成する。前記投射光学系は、前記生成された画像光の光軸上に配置された第1の屈折力を持つ第1のレンズ群と、前記光軸上に配置された第2の屈折力を持つ第2のレンズ群と、前記第1のレンズ群を移動させる第1の移動機構と、前記第1の屈折力、前記第2の屈折力、及び前記第1のレンズ群の移動に応じて、前記第2のレンズ群を移動させる第2の移動機構とを有する。
