Abstract
(EN)
A head-mounted display (100) according to this embodiment is provided with: a first mirror (121L), (121R) which synthesizes display light for forming a display image and outside light from ahead of a user; a light-blocking shutter (120) which is disposed ahead of the first mirror (121L), (121R), and forms a light-blocking region that blocks the outside light and a transmission region that transmits the outside light; a head tracking unit (160) which detects a movement of the head of the user; and a light blocking control unit (154) which controls the light-blocking region and the transmission region according to the result of the detection by the head tracking unit (160).
(FR)
L'invention concerne un visiocasque (100) selon ce mode de réalisation étant pourvu d'un premier miroir (121L), (121R) qui synthétise une lumière d'affichage pour former une image d'affichage et une lumière extérieure provenant de l'avant d'un utilisateur ; un obturateur de blocage de lumière (120) disposé à l'avant du premier miroir (121L), (121R) et formant une région de blocage de lumière qui bloque la lumière extérieure ainsi qu'une région de transmission transmettant la lumière extérieure ; une unité de suivi de tête (160) qui détecte un mouvement de la tête de l'utilisateur ; et une unité de commande de blocage de lumière (154) qui commande la région de blocage de lumière et la région de transmission en fonction du résultat de la détection par l'unité de suivi de tête (160).
(JA)
本実施の形態にかかるヘッドマウントディスプレイ(100)は、表示画像を形成するための表示光と、ユーザの前方からの外光とを合成する第1ミラー(121L)、(121R)と、第1ミラー(121L)、(121R)の前方に配置され、外光を遮光する遮光領域と外光を透過する透過領域とを形成する遮光シャッタ(120)と、ユーザの頭部の動きを検出するヘッドトラッキング部(160)と、ヘッドトラッキング部(160)での検出結果に応じて、遮光領域と透過領域とを制御する遮光制御部(154)と、を備えたものである。
