ABSTRACT:
Provided is a photoelectric conversion device, including: a plurality of photoelectric conversion blocks each including 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, in which the photoelectric conversion element resetting means resets the photoelectric conversion element every time the voltage of the photoelectric conversion element is transferred and for a standby period, during a reading period. Therefore, it is possible to perform accurate image reading by reducing the influence of a foreign matter adhered to a light receiving surface of a photoelectric conversion device.
