Abstract
A field-sequential-type image forming device which includes: a light valve element which divides one field of a color image to sectors corresponding to primary colors different from each other and forms images corresponding to the primary colors during periods of the respective sectors; a light emission control unit which controls light emission quantities of the light sources; and an image control signal outputting unit which outputs control signals to the light valve element. In such an image forming device, the image control signal outputting unit outputs signals for forming the image by controlling light quantities of lights emitted from the primary color sources during the primary color light emission period and light quantity correction signals for controlling light quantity of the image corresponding to the positions of the pixels which form the image during the high-brightness light emission period.
