Abstract
In a printer head constituted by a large number of linearly arranged LEDs, a lighting time designator receives image data at a period corresponding to one scanning period, designates a lighting time of each LED within one scanning period in accordance with image data corresponding to each LED and the lighting capacity of each LED, and outputs lighting time data. A lighting mode designator determines a lighting mode for designating a timing, within one scanning period, at which each LED is caused to emit light, on the basis of image data, and outputs lighting mode designation data. A light timing controller divides one scanning period into a plurality of time intervals and supplies the lighting time data to the printer head a plurality of number of times within one scanning period at the time intervals on the basis of the lighting mode designation data, thereby selectively causing the respective LEDs to emit light.
