1. An imaging device, comprising:
a clock signal generator that generates a first clock signal and supplies the first clock signal to a clock signal path;
a plurality of light-receiving pixels that is provided side by side in a first direction and grouped into a plurality of pixel groups in the first direction, the plurality of light-receiving pixels each including a light-receiving circuit, a comparison circuit, and a latch circuit, the light-receiving circuit generating a pixel signal corresponding to an amount of received light, the comparison circuit performing a comparison operation on a basis of the pixel signal and a reference signal having a ramp waveform, the latch circuit latching a time code on a basis of a result of comparison by the comparison circuit;
a plurality of gate circuits that is provided side by side in the first direction and provided in association with the plurality of pixel groups respectively, the plurality of gate circuits being each configured to output a signal in the clock signal path as a second clock signal and controlling, on a basis of a control signal, whether or not to output the second clock signal; and
a plurality of counters that is provided side by side in the first direction and provided in association with the plurality of gate circuits respectively, the plurality of counters each generating the time code on a basis of the second clock signal supplied from a corresponding gate circuit among the plurality of gate circuits and supplying the generated time code to two or more light-receiving pixels belonging to a corresponding pixel group among the plurality of pixel groups.
