Abstract:
1. A photoelectric conversion device comprising: a plurality of unit pixels, each having a first photoelectric conversion unit, a second photoelectric conversion unit, a pixel output unit for outputting a signal based on an amount of electric charge generated by at least one of the first and second photoelectric conversion units, and a first transfer unit for transferring electric charge generated by the first photoelectric conversion unit to the pixel output unit; and a monitoring unit for controlling a charge-accumulation operation of the first photoelectric conversion unit based on a signal output from the pixel output unit, the signal being generated based on an amount of electric charge generated by the second photoelectric conversion unit; wherein the photoelectric conversion device maintains an electrical connection of the second photoelectric conversion unit and the pixel output unit during the charge-accumulation operation of the first photoelectric conversion unit.
