Abstract
A photoelectric conversion device includes a pixel array and a reading unit including a plurality of reading circuits each configured to read a signal from the pixel array. Each reading circuit includes a sample-and-hold unit including a first sample-and-hold circuit configured to hold a reset level output from the pixel array and a second sample-and-hold circuit configured to hold a photo signal level output from the pixel array. The plurality of reading circuits include first reading circuits forming a first group and second reading circuits forming a second group. At least some of the plurality of first reading circuits are controlled by a first control signal given via a first control line, and at least some of the plurality of second reading circuits are controlled by a second control signal given via a second control line.
