Title (EN) IMAGE PROJECTION DEVICE
(FR) DISPOSITIF DE PROJECTION D'IMAGE
(JA) 画像投写装置
Abstract:
(EN) Disclosed is an image projection device that projects an image to a projection surface, said image projection device being provided with an image forming element, a refractive optical unit, and a reflective optical system unit. The image forming element forms, on the basis of an image signal, an image to be projected to the projection surface. The refractive optical unit has a refractive optical system that includes a plurality of lenses which guide, to the direction of the projection surface, light of the image formed by the image forming element. A reflective optical system has: a reflective optical system, which includes a first mirror that reflects the light guided by the refractive optical system, and a second mirror that reflects, toward the projection surface, light reflected by the first mirror; and a blocking section (20), which includes a blocking surface that is provided at a position of blocking a part of the light, which has been generated by the refractive optical unit, and which has passed between the first mirror and the second mirror.
(FR) L'invention concerne un dispositif de projection d'image qui projette une image sur une surface de projection, ledit dispositif de projection d'image comprenant un élément de formation d'image, une unité optique de réfraction et une unité de système optique réfléchissant. L'élément de formation d'image forme, sur la base d'un signal d'image, une image à projeter sur la surface de projection. L'unité optique de réfraction a un système optique de réfraction qui comprend une pluralité de lentilles qui guident, vers la direction de la surface de projection, la lumière de l'image formée par l'élément de formation d'image. Un système optique réfléchissant comprend : un système optique réfléchissant qui comprend un premier miroir qui réfléchit la lumière guidée par le système optique de réfraction, et un second miroir qui réfléchit, vers la surface de projection, la lumière réfléchie par le premier miroir ; et une section de blocage (20) qui comprend une surface de blocage qui est disposée dans une position pour bloquer une partie de la lumière, qui a été générée par l'unité optique de réfraction, et qui a traversé le premier miroir et le second miroir.
(JA) 本開示に係る画像投写装置は、投写面に対して画像を投写する画像投写装置であって、画像形成素子と、屈折光学ユニットと、反射光学系ユニットと、を備える。画像形成素子は、画像信号に基づいて投写面に投写する画像を形成する。屈折光学ユニットは、画像形成素子によって形成された画像の光を投写面の方向へ導く複数のレンズを含む屈折光学系を有する。反射光学系は、屈折光学系によって導かれた光を反射する第1ミラーおよび第1ミラーによって反射された光を投写面に向かって反射する第2ミラーを含む反射光学系と、屈折光学ユニットにおいて生じ、第1ミラーと第2ミラーとの間を通過する一部の光を、遮蔽する位置に設けられた遮蔽面を含む遮蔽部と、を有する。
