Abstract
Improved is performance of a solid-state image sensor that detects presence or absence of a photon. The solid-state image sensor includes a light-receiving substrate and a logic substrate. In the solid-state image sensor, there is disposed, on the light-receiving substrate, a plurality of avalanche photodiodes, each of the avalanche photodiodes generating a current corresponding to incident of a photon. Furthermore, in the solid-state image sensor, there is disposed, on the logic substrate, a counter that counts the number of photons on the basis of a current of a selected avalanche photodiode among the plurality of avalanche photodiodes.
