Claim 6:
7. An image sensor control method for controlling an image sensor comprising a plurality of pixels arranged one-dimensionally or two-dimensionally, wherein in the image sensor, each pixel includes:
a photoelectric conversion portion configured to generate a charge in an amount according to an intensity of incident light; and
a charge accumulation portion provided separately from the photoelectric conversion portion and configured to accumulate the charge, and the control method comprises:
a first step of removing 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 on the image sensor;
a second step being alternately repeated with the first step and of transferring the charge generated in the photoelectric conversion portion by incidence of the second light to the charge accumulation portion; and
a third step of reading out the charge from the charge accumulation portion after the second step 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.
