Claim 0:
1. An image sensor comprising:
a plurality of pixels arranged one-dimensionally or two-dimensionally, wherein each pixel includes:
a photoelectric conversion configured to generate a charge in an amount according to an intensity of incident light;
a first gate configured to control removal of the charge accumulated in the photoelectric conversion portion from the pixel;
a charge accumulation portion provided separately from the photoelectric conversion portion and configured to accumulate the charge;
a second gate provided between the photoelectric conversion portion and the charge accumulation portion and configured to control a transfer of the charge from the photoelectric conversion portion to the charge accumulation portion; and
a third gate configured to control readout of the charge from the charge accumulation portion, and wherein
the first gate is configured to remove the charge generated in the photoelectric conversion portion by incidence of first light from the pixel, the first light and a second light being temporally alternately incident,
the second gate is configured to transfer the charge generated in the photoelectric conversion portion by incidence of the second light to the charge accumulation portion,
the third gate is configured to perform control for reading out the charge from the charge accumulation portion after the charge transfer to the charge accumulation portion is performed n times (n is an integer of 1 or more), and
wherein the number n of the charge transfers is individually set for each pixel.
