Abstract
Abstract Three lines' worth of an image are displayed on a columnar display unit 11 comprising a plurality (for example, three) of one-dimensional display devices; this image light beam is made incident on perpendicular deflection means 14 , and using the perpendicular deflection means 14, this image light beam is deflected and scanned at high speed in directions perpendicular to the longitudinal direction of the columnar display unit 11 to obtain a two-dimensional image. A plurality of one-dimensional display devices is used, so that compared with conventional devices in which only a single one-dimensional display device is used, even if the rewrite speed (scanning speed) per one-dimensional display device is slow, good image quality free of flicker can be obtained. By further extending this in a configuration using a plurality of columnar display units, a single image can be divided into a plurality of images and displayed in a row on a screen. In order to prevent seams in this juxtaposed display of a plurality of images from being conspicuous, when overlapping parts are provided in the scanned range of the plurality of images, a correction image capture member 47, correction computation member 48, and correction processing member 49 can be used to correct the brightness of the overlapping parts, enabling display of a single high-resolution, large-screen image.
