摘要

An image sensor, includes: a plurality of pixels arranged along a first direction, each of which includes a photoelectric conversion unit that generates an electric charge through photoelectric conversion of light, and outputs a signal generated based upon the electric charge generated in the photoelectric conversion unit; a first signal line to which signals from one or more pixels among the plurality of pixels are output; a second signal line to which a signal from another pixel among the plurality of pixels is output; and an arithmetic unit that executes an arithmetic operation with a signal generated by combining the signals from the one or more pixels output to the first signal line and the signal output to the second signal line.
