1. An image sensor comprising:
a plurality of pixels each having an avalanche photodiode; and
a voltage supply that supplies to the avalanche photodiodes of the plurality of pixels a reverse bias voltage that periodically and reciprocally changes between a first voltage and a second voltage,
wherein the first voltage is larger than a smallest breakdown voltage among breakdown voltages of the avalanche photodiodes of the plurality of pixels and the second voltage is larger than a largest breakdown voltage among the breakdown voltages of the avalanche photodiodes of the plurality of pixels, and
wherein the first and second voltages are set based on the respective breakdown voltage.
