IMAGE PROJECTION DEVICE

DISPOSITIF DE PROJECTION D'IMAGE
(JA)
画像投影装置
Abstract:
(EN)
The purpose of the present invention is to provide a user with a quality image. An image projection device according to the present invention comprises: a light source (10) for emitting laser light (40); a control unit (32) that generates the laser light (40) based on input image data and controls the laser light (40) emitted from the light source (10); a scanning mirror (14) that scans the laser light (40) emitted from the light source (10), thereby creating scanning light (42); and a projection module (16) that irradiates the retina (52) in a user's eye (50) with the scanning light (42) to thus project an image onto the retina (52). The projection module (16) includes: an optical system (18) that allows the scanning light (42) emitted by the scanning mirror (14) to converge on a virtual plane (62) located outside the user's eye (50) at an angle (θ2) substantially the same as the scanning angle (θ1) of the scanning mirror (14); and an optical system 24 that allows the scanning light (42) passing through the virtual plane (62) to converge on a virtual plane (64) located near the pupil (54) inside the user's eye (50) at an angle (θ4) substantially the same as the emission angle (θ3) from the virtual plane (62).
(FR)
La présente invention a pour objet de fournir à un utilisateur une image de qualité. Un dispositif de projection d'image selon la présente invention comprend : une source de lumière (10) servant à émettre une lumière laser (40) ; une unité de commande (32) qui génère la lumière laser (40) sur la base de données d'image d'entrée et régule la lumière laser (40) émise par la source de lumière (10) ; un miroir de balayage (14) qui balaie la lumière laser (40) émise par la source de lumière (10), créant ainsi une lumière de balayage (42) ; et un module de projection (16) qui irradie la rétine (52) dans l’œil d'un utilisateur (50) au moyen de la lumière de balayage (42) pour projeter ainsi une image sur la rétine (52). Le module de projection (16) comprend : un système optique (18) qui permet à la lumière de balayage (42) émise par le miroir de balayage (14) de converger sur un plan virtuel (62) situé à l'extérieur de l’œil de l'utilisateur (50) à un angle (θ2) sensiblement identique à l'angle de balayage (θ1) du miroir de balayage (14) ; et un système optique (24) qui permet à la lumière de balayage (42) traversant le plan virtuel (62) de converger sur un plan virtuel (64) situé à proximité de la pupille (54) à l'intérieur de l’œil de l'utilisateur (50) à un angle (θ4) sensiblement identique à l'angle d'émission (θ3) à partir du plan virtuel (62).
(JA)
本発明はユーザに良好な画像を提供することを目的とする。本発明の画像投影装置は、レーザ光(40)を出射する光源(10)と、入力された画像データに基づいたレーザ光(40)を生成して、光源(10)からのレーザ光(40)の出射を制御する制御部(32)と、光源(10)から出射されたレーザ光(40)を走査して走査光(42)とする走査ミラー(14)と、走査光(42)をユーザの眼(50)の網膜(52)に照射して網膜(52)に画像を投影する投影部(16)と、を備え、投影部(16)は、走査ミラー(14)から出射される走査光(42)をユーザの眼(50)の外側に位置する仮想面(62)に走査ミラー(14)の走査角度(θ1)と略同じ角度(θ2)で収束させる光学系(18)と、仮想面(62)を通過した走査光(42)をユーザの眼(50)の内側で瞳孔(54)近傍に位置する仮想面(64)に仮想面(62)からの出射角度(θ3)と略同じ角度(θ4)で収束させる光学系24と、を備える。
