This image display device (1) displays an image via optical scanning by driving a mirror part, which reflects a light beam emitted by a light source (14, 15), in both a primary scanning direction and a secondary scanning direction that intersects said primary scanning direction. Said image display device is provided with a controlling means (13) that controls the light source on the basis of the brightness of a displayed one-frame image so as to vary light-beam emission periods for pixel drawing periods, i.e. periods for drawing pixel data corresponding to the displayed image. |
