1. An imaging device comprising:
a pixel block comprising a pixel and a second circuit; and
a first circuit,
wherein the pixel is configured to obtain a first signal by photoelectric conversion,
wherein the second circuit is configured to generate a second signal on the basis of a sum of the first signals, and
wherein the first circuit is configured to generate a third signal by binarizing the second signal.
