IMAGE DISPLAY DEVICE

摘要

An image display device (1) for displaying an image by scanning a light flux and projecting an image on a retina of an observer. The device includes an emission section (10) for emitting a light flux according to a video signal representing an image, a scan section (50) for scanning the light flux emitted from the emission section, and a control section (110). When a setting condition is established without depending on the observer operation during image display, the control section (110) controls the emission section to emit a light flux at a low output level preset to a level lower than the normal level but greater than 0.
