Photoelectric conversion device and method of driving photoelectric conversion device

A photoelectric conversion device comprising:

• a plurality of pixels arranged to form a plurality of rows and a plurality of columns and each including a photoelectric conversion unit;
• a plurality of output line groups arranged corresponding to the plurality of columns and each including at least a first output line and a second output line;
• a pixel control unit configured to control a readout of signals from the plurality of pixels to the plurality of output line groups in units of the rows;
• and
• an amplitude limiting unit configured to limit ranges of signal amplitudes of the signals output to the plurality of output line groups,
• wherein the pixel control unit is configured to execute a first scan in which signals of pixels connected to the first output line of each column are sequentially read out in units of the row, and a second scan in which signals of pixels connected to the second output line of each column are sequentially read out in units of the row,
• wherein a period in which a signal of a first pixel is read out to the first output line by the first scan and a period in which a signal of a second pixel connected to the second output line adjacent to the first output line to which the first pixel is connected is read out to the second output line by the second scan overlap each other, and
• wherein the amplitude limiting unit is configured to limit ranges of signal amplitudes in the first output line and the second output line so that a maximum signal amplitude in the first output line and a maximum signal amplitude in the second output line are different.
