ABSTRACT:
Light quantity unevenness is corrected at high resolution to improve image quality, without increasing a speed of system clock. Pixel correction data which is to correct a light emission characteristic of each light emission element by the pixel unit is prepared for plural lines, and the pixel correction data for the plural lines are periodically changed to modify a light emission driving time of each light emission element.
