1. A photoelectric conversion device comprising:
a pixel array including a plurality of pixels arranged to form a plurality of rows and a plurality of columns; and
a reading unit including a plurality of reading circuits each configured to read a signal from the pixel array,
wherein each of the plurality of reading circuits includes a sample-and-hold unit, the sample-and-hold unit including (1) a first sample-and-hold circuit configured to hold a reset level output from the pixel array and (2) a second sample-and-hold circuit configured to hold a photo signal level output from the pixel array,
wherein the plurality of reading circuits include (1) a plurality of first reading circuits forming a first group and (2) a plurality of second reading circuits forming a second group,
wherein at least some of the plurality of first reading circuits are controlled by a first control signal given via a first control line passing through the plurality of reading circuits, and
wherein at least some of the plurality of second reading circuits are controlled by a second control signal given via a second control line passing through the plurality of reading circuits.
