Abstract
A light source driving apparatus according to an embodiment of the present technology includes a reception unit, an output unit, a sample unit, and a timing output unit. The reception unit receives a pulse modulation signal for pulse-driving a light source. The output unit outputs a delay modulation signal obtained by delaying the received pulse modulation signal to the light source. The sample unit samples, at a predetermined timing, a light amount of the light source driven on the basis of the delay modulation signal. The timing output unit outputs, to the sample unit, a pulse fall timing of the received pulse modulation signal as the predetermined timing.
