Abstract
An image sensor device provided with a linear array of photoelectric converting elements each having a capacitor on a control electrode area of a semiconductor transistor is disclosed. The image sensor device is provided with means for sequentially selecting the photoelectric converting elements, and the potential of the control electrode area of the selected photoelectric converting element is controlled through said capacitor, thereby accumulating the carriers generated by photoexcitation in said control electrode area and reading a voltage generated according to the amount of carrier accumulation or dissipating thus accumulated carriers.
