Zusammenfassung:To reduce time required for a driver to visually recognize display contents of a virtual image at a predetermined display position after power supply of an HUD is turned on.SOLUTION: An image display device 100 according to the present invention comprises: a projection unit 120 that projects display light corresponding to an image visually recognized as a virtual image through a projection surface; a rotating reflection unit 140 that is provided rotatably and reflects the display light toward the projection surface; a driving unit 150 that rotates the rotating reflection unit 140 to change an angle to reflect the display light; and a control unit 110 that adjusts a display area of the image in the projection unit 120 according to the angle so that the virtual image is visually recognized at a predetermined position on the projection surface.SELECTED DRAWING: Figure 4 【課題】HUDの電源が投入された後、虚像の表示内容を所定の表示位置で視認できるまでに要する時間を短縮すること。【解決手段】本発明にかかる画像表示装置100は、投影面を介して虚像として視認される画像に対応する表示光を投射する投射部120と、回動可能に設けられ、前記表示光を前記投影面に向けて反射させる回動反射部140と、前記回動反射部140を回動させて前記表示光を反射させる角度を変更する駆動部150と、前記投影面における所定の表示位置で前記虚像が視認されるように、前記投射部120における前記画像の表示領域を、前記角度に応じて調整する制御部110と、を備える。【選択図】図4
