Abstract:
(EN) This image display device includes a light source for radiating light, an optical scanning unit for scanning a prescribed scan area with light from the light source and drawing a display image, a luminous energy detection unit for detecting the luminous energy of light from the light source, a storage unit for storing a relationship between a control current supplied to the light source and the luminous energy, and a control unit for controlling the control current on the basis of the relationship between the control current and the luminous energy stored in the storage unit so that the display image is displayed by light from the light source. When the optical scanning unit scans an external area of the display image, the control unit detects, using the luminous energy detection unit, the luminous energy of light with which the area is scanned, and updates the relationship between the control current and the luminous energy stored in the storage unit on the basis of the detected luminous energy.
(FR) L'invention concerne un dispositif d'affichage d'image comprenant : une source de lumière pour émettre de la lumière; une unité de balayage optique pour balayer une zone de balayage prescrite avec la lumière provenant de la source de lumière et dessiner une image d'affichage; une unité de détection d'énergie lumineuse pour détecter l'énergie lumineuse de la lumière provenant de la source lumineuse; une unité de stockage pour stocker une relation entre un courant de commande fourni à la source lumineuse et l'énergie lumineuse, et une unité de commande pour commander le courant de commande sur la base de la relation entre le courant de commande et l'énergie lumineuse stockée dans l'unité de stockage, de sorte que l'image d'affichage est affichée par la lumière provenant de la source de lumière. Lorsque l'unité de balayage optique balaie une zone externe de l'image d'affichage, l'unité de commande : détecte, à l'aide de l'unité de détection d'énergie lumineuse, l'énergie lumineuse de la lumière avec laquelle la zone est balayée; et met à jour la relation entre le courant de commande et l'énergie lumineuse stockée dans l'unité de stockage, sur la base de l'énergie lumineuse détectée.
(JA) 画像表示装置は、光を出射する光源と、前記光源からの光で所定の走査領域を走査して表示画像を描画する光走査部と、前記光源からの光の光量を検出する光量検出部と、前記光源に供給される制御電流と光量との関係を記憶する記憶部と、前記記憶部に記憶された前記制御電流と光量との関係に基づき、前記光源からの光によって前記表示画像を表示するように前記制御電流を制御する制御部と、を含む。前記制御部は、前記光走査部が前記表示画像の外部の領域を走査する際、当該走査する光の光量を前記光量検出部によって検出し、検出した光量に基づき前記記憶部に記憶された制御電流と光量との関係を更新する。
