ABSTRACT:
An image display apparatus includes a light source for emitting a plurality of light beams arranged in a direction corresponding to a sub-scanning direction, a light source driver for individually modulating intensities of the plurality of light beams; a light scanning unit for performing main scanning and sub-scanning; an image display screen for receiving the plurality of light beams scanned in the main and sub-scanning directions; and a controller, wherein, in one frame period, a distance of movement of the light irradiation positions on the image display screen moved by one sub-scanning is a distance obtained by multiplying an interval between adjacent two scanning lines in the sub-scanning direction on the image display screen by a predetermined integer which is an integer smaller than number of the plurality of light beams arranged in the direction corresponding to the sub-scanning direction.
