Abstract

A SIT (Static Induction Transistor) image sensor with a high-sensitivity and a high-fidelity is disclosed. The image sensor comprises a SIT image cell array and a scanning circuit which scans in turn a plurality of SIT image cells in such a manner that respective scanning time in all the cells are equal throughout a sequential scanning operation for the SIT image sensor. A reading line and a refreshing line may be combined into a single line. A differential amplifier is provided for correcting a picture element information to remove a noise component therefrom.
