Photoelectric conversion device, image sensor, optical reader, and method of driving photoelectric conversion device

A photoelectric conversion device, comprising:

• a plurality of photoelectric conversion blocks each comprising:
• a photoelectric conversion element;
• photoelectric conversion element resetting means for supplying an initialization potential to the photoelectric conversion element to reset the photoelectric conversion element;
• and
• transfer means for transferring a voltage of the photoelectric conversion element,
• wherein the photoelectric conversion element resetting means resets the photoelectric conversion element every time, during a reading period, the voltage of the photoelectric conversion element is transferred and continues resetting the photoelectric conversion element for a standby period, and wherein the resetting means includes:
• a switch connected with a terminal for the initialization potential;
• and
• reset signal output means for controlling an on/off state of the switch;
• and wherein
• the reset signal output means outputs to the switch a first reset signal for resetting the photoelectric conversion element, every time during the reading period the voltage of the photoelectric conversion element is transferred, and
• the reset signal output means outputs to the switch a second reset signal for keeping the photoelectric conversion element reset for the standby period.
