LIGHT EMITTING ELEMENT DRIVING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a light emitting element driving device that can stably control light emitting elements without relying upon the number of light emitting elements that emit light at the time of deciding the transmission timing of image signals.

SOLUTION: The light emitting element driving device which controls a plurality of light emitting elements (LD1-LD4) is provided with means (510 and 310) which control light quantities of selectively driven light emitting elements based on the number of the selectively driven light emitting elements at the time of deciding the transmission timing of image signals to the light emitting elements (LD1-LD4).
