Abstract
In a photoelectric conversion device, in a first period in which a respective different offset voltage is supplied to a comparator included in each of a plurality of AD conversion circuits, a control unit performs control to bring the offset voltage into a first driving state in which a voltage change amount per unit time of the offset voltage is a first voltage amount, and, in a second period in which a ramp signal is supplied to the comparator included in each of the plurality of AD conversion circuits, the control unit performs control to bring the ramp signal into a second driving state in which a voltage change amount per unit time of the ramp signal is a second voltage amount, wherein the first voltage amount is larger the second voltage amount.
