Abstract
Provided is a light source driving device includes a light emission drive unit, a drive signal generation unit, a phase difference detection unit, and a delay detection unit. The light emission drive unit supplies a light emission current for causing a light source to emit light. The drive signal generation unit generates a drive signal for driving the light emission drive unit on the basis of a light emission control signal for causing the light source to emit light. The phase difference detection unit detects the phase difference between a light emission period of the light source and the light emission control signal. The delay detection unit detects a delay in the light emission on the basis of the detected phase difference.
