Abstract
A photodetection device according to the present disclosure includes: a light-receiving section including a light-receiving element, a first switch, a second switch, and a signal generator, the first switch that couples the light-receiving element to a first node by being turned on, the second switch that applies a predetermined voltage to the first node by being turned on, and the signal generator that generates a pulse signal on the basis of a voltage at the first node; a controller that controls operations of the first switch and the second switch; a detector that detects a timing at which the pulse signal is changed, on the basis of the pulse signal; and an output section that outputs a detection signal corresponding to a detection result by the detector when the second switch is turned on.
