1. An imaging device comprising:
a pixel array including first pixels in a first row and second pixels in a second row;
first circuitry configured to:
supply a first voltage to the first pixels and the second pixels in a first period in a first frame period to set the first pixels and the second pixels to a first sensitivity;
supply a second voltage to the first pixels and the second pixels in a third period immediately subsequent to the first period in the first frame period to set the first pixels and the second pixels to a second sensitivity, the second voltage being different from the first voltage, the second sensitivity being less than the first sensitivity; and
supply the first voltage to the first pixels and the second pixels in a second period immediately subsequent to the third period in the first frame period to set the first pixels and the second pixels to the first sensitivity; and
second circuitry configured to:
in the first period, perform pixel signal readout on the first pixels and,
in the second period, perform pixel signal readout on the second pixels.
