ABSTRACT:
A photoelectric converting device is provided with a control electrode area consisting of a semiconductor of a first conductive type, first and second main electrode areas consisting of a semiconductor of a second conductive type different from the first conductive type, and a drive line capacitively coupled to the control electrode area for controlling the potential thereof, and adapted to read a signal from the first main electrode area, by the potential control of the control electrode area, based on a charge generated by an incident light energy and accumulated in the control electrode area. The potentials of the first main electrode areas and of the drive line are elevated during the light signal accumulating operation to elevate the potential of the control electrode area, thereby rendering the potential difference between the control electrode area and the second main electrode area smaller than at the end of charge resetting of the control electrode area.
