Abstract
A distance measuring apparatus is provided which includes an illuminator, a plurality of photodetectors which detect reflected light arising from reflection of light, as emitted from the illuminator, from an object using SPADs, a time measuring unit which measures time elapsed after the emission of light from the illuminator until a number of the photodetectors which is larger than a given value have detected light, a timing controller which instructs the illuminator to emit the light, activates the SPADs in a Geiger mode, and instructs the time measuring unit to execute the time measurement, and a timing instruction unit which determines a light emission timing and an activation start timing of each of the SPADs for the timing controller.
