Abstract
A plurality of photodetectors form a light receiving group, and a plurality of the light receiving groups form one pixel. A light receiving array is provided with one or more of such pixels. The photodetectors each output a pulse signal in response to irradiation of a photon. A measuring unit is provided for each of the plurality of light receiving groups. The measuring unit generates time information representing an elapsed time from an irradiation timing input from outside and light quantity information acquired at each of one or more timings identified from the time information, in accordance with the pulse signal output from the light receiving group. The number of the photodetectors outputting the pulse signal among the plurality of photodetectors belonging to the light receiving group is used as the light quantity information.
