ABSTRACT:
A solid state image sensing device including a number of pixels arranged in a matrix form and comprised of lateral or vertical static induction transistors formed in a semiconductor chip, and a dummy pixel array arranged along a column in the chip and shielded from an incident light input. When successive pixels on a row are read out to derive picture signals, a dummy pixel on the same row is repeatedly read out to derive dark signals in synchronism with the reading out operation for respective pixels on the same row. A differential amplifier is formed in the semiconductor chip to derive a difference signal between a picture signal and a dark signal which are read out simultaneously.
