Abstract

PURPOSE: To substitute a signal, which is obtained by synthesizing upper and lower cells on scanning lines adjacent to a faulty cell, for the output signal of the faulty cell by regarding the cell as the faulty cell when the output signal of the specific cell is not between a white level and a black level in the signal compensating system of a solid image sensor.
CONSTITUTION: Picture signals from a solid image sensor are applied to input terminal IN, and are applied to delay circuits 1 and 1a which have a delay time equal to the scanning time of a horizontal scanning line. White level reference signal W and black level reference signal B are compared with each other, and switch 3 is opened and switch 4 is closed when a faulty cell is discriminated. Then, the signal obtained by synthesizing upper and lower normal signals a and c of the faulty cell in adder 5 and operating the average value of them in attenuator 6 is substituted for signal b of faulty cell 9 and is outputted to terminal OUT.
