Abstract
(EN) [Problem] To provide an image display device and a control method with which it is possible to suppress shake in an image without using a mechanical structure. [Solution] An image display device that can project an optical image, said image display device comprising: a reflection part that reflects the optical image; a projection optical system that projects the reflected optical image; a detection unit that detects movement of the image display device; and a control unit that changes the reflective characteristics of a constituent material of the reflection part in accordance with the movement, thereby controlling the projection angle of the optical image.
(FR) Le problème décrit par la présente invention est de fournir un dispositif d'affichage d'image et un procédé de commande qui permettent de supprimer un tremblement dans une image sans utiliser de structure mécanique. À cet effet, l'invention concerne un dispositif d'affichage d'image qui peut projeter une image optique, ledit dispositif d'affichage d'image comprenant : une partie de réflexion qui réfléchit l'image optique ; un système optique de projection qui projette l'image optique réfléchie ; une unité de détection qui détecte le mouvement du dispositif d'affichage d'image ; et une unité de commande qui modifie les caractéristiques de réflexion d'un matériau constitutif de la partie de réflexion conformément au mouvement, ce qui permet de commander l'angle de projection de l'image optique.
(JA) [課題]機械的な構造を用いずに画像のブレを抑制可能な画像表示装置、及び制御方法を提供する。 [解決手段]光学像を投影可能な画像表示装置であって、光学像を反射する反射部と、 反射された光学像を投影する投影光学系と、画像表示装置の動きを検出する検出部と、動きに応じて、反射部が有する構成材の反射特性を変更することにより光学像の投影角度を制御する制御部と、を備える、画像表示装置。
