| 摘要 |
A light source driving device which drives a plurality of light emitting parts provided in a light source to emit a plurality of light beams based on image information, includes a plurality of driving circuits configured to drive the plurality of light emitting parts. Each of the driving circuits includes a signal generation circuit that generates a modulation signal to control a light emitting intensity of the corresponding light emitting part based on the image information, a detection circuit that detects a light emitting status of the corresponding light emitting part; and a light emitting circuit that outputs a driving signal to the corresponding light emitting part to emit a light beam in accordance with the modulation signal and adjustment data obtained based on the light emitting status of at least one of the plurality of light emitting parts. |
