1. An image sensor, comprising:
a plurality of pixels arranged side by side in a row direction and in a column direction, each of the plurality of pixels comprising:
a photoelectric conversion unit that converts light to charge;
a transfer unit that transfers the charge converted by the photoelectric conversion unit;
a floating diffusion to which the charge converted by the photoelectric conversion unit is transferred by the transfer unit; and
a reset unit that resets a potential of the floating diffusion to a reset potential;
a first signal line to which a first signal is outputted, the first signal being based upon the potential of the floating diffusion to which the charge has been transferred by the transfer unit from the photoelectric conversion unit; and
a second signal line to which a second signal is outputted, the second signal being based upon the reset potential of the floating diffusion that has been reset by the reset unit,
wherein each of the plurality of pixels further comprises:
an amplifier for outputting the first signal and the second signal, the amplifier including a gate connected to the floating diffusion;
a first selection switch for outputting to the first signal line;
a second selection switch for outputting the second signal from the amplifier to the second signal line; and
a current source for supplying current to the amplifier.
