Abstract
A visual display system in which light from a light source is modulated by a spatial light modulator having a plurality of controllable elements arranged in a first dimension. The modulated light is scanned by an optical scanning device along a second dimension to display an image. An exposure control apparatus has a lens, a photoelectric conversion device, and a spatial light modulator. The spatial light modulator varies the amount of light received from the lens and supplied to the photoelectric conversion device, thereby controlling the exposure of the image focused by the lens.
