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 the first sample and hold circuit and the second sample and hold circuit included in one of the plurality of first reading circuits are controlled by a first control signal given via a first control line, and
wherein the first sample and hold circuit and the second sample and hold circuit included in one of the plurality of second reading circuits are controlled by a second control signal given via a second control line.
