SOLID STATE IMAGING DEVICE WITH ADAPTIVE PIXEL CORRECTION

A solid state imaging device is disclosed which includes a solid state sensor for converting an external scene into electrical signals, an A/D converter for converting output signals from the solid state sensor into digital signals, a frame memory for storing offset signals of the solid state sensor, and an arithmetic unit for subtracting the offset signals stored in the frame memory from the digital signals of the A/D converter. The signals from the arithmetic unit are output through a D/A converter and a synchronization adding circuit. In the thus constituted solid state imaging device, a judgement as to the level of the offset signal from the frame memory is made. If this level is outside a predetermined range, it is judged that there is a defective pixel. Interpolation is then effected with neighboring pixel signals in a spatial processor.
