Abstract
A solid state image sensor includes at least a plurality of pixel cells and a vertical scanning circuit. Each of the pixel cells includes an avalanche photodiode, a floating diffusion portion, a transfer transistor, a reset transistor, an amplifier transistor, a selection transistor, a count transistor, and a capacitor. The amplifier transistor outputs a voltage signal responsive to the amount of charge stored in the floating diffusion portion. The capacitor has terminals one of which is connected to the count transistor. The vertical scanning circuit is configured to be able to supply different levels of voltages to the other terminals of the capacitors.
