Claim 4:
5. An imaging device comprising:
a plurality of pixels, a first circuit, and a second circuit,
wherein the first circuit is configured to supply a first potential to the plurality of pixels,
wherein the plurality of pixels are each configured to obtain first data and second data,
wherein the plurality of pixels are each configured to generate third data that is a difference between the first data and the second data,
wherein the plurality of pixels are each configured to generate fourth data by adding a potential based on the first potential to the third data, and
wherein the second circuit is configured to generate fifth data corresponding to a difference between a sum of the third data output from the plurality of pixels and a sum of the fourth data output from the plurality of pixels.
