Abstract: A photoelectric converting device is provided with photoelectric converting cells. Each cell is provided with a semiconductor transistor and a capacitor. The transistor is composed of two main electrode semiconductor areas (15, 4) of a conductivity type and a control electrode semiconductor area (9) of opposite conductivity type. The capacitor controls the potential of said control electrode area in a floating state. The cell is capable of an accumulating operation for accumulating photo-induced carriers in said control electrode area, a read- out operation for reading an output controlled by a voltage generated by said accumulation, and a refreshing operation for dissipating the carriers accumulated in said control electrode area, by means of controlling the potential of said control electrode area in floating state through said capacitor. The device comprises a semiconductor area (33) of a high concentration and of a same conductive type as that of said control electrode area in an element isolation area which is provided in said main electrode area for electrically isolating said photoelectric converting cells, thereby constituting a transistor structure in combination with said control electrode area.
