Abstract
PURPOSE: To increase the video quality and the resolution, by synthesizing the output signal of succeeding cell and preceding cell of defective cells and replacing the output of the defective cells.
CONSTITUTION: The video signal from the solidstate image sensor is fed to the terminal IN, and the output signal compensated is fed to the terminal OUT. The reference levels REF1 and 2 are taken as closer value to white and black level of each video signal. If the output signal from the defective cell appears at the output of the delay circuit 1, the output is greater than the white level or lower than the black level. Accordingly, the comparator 5 produces an output and the switch 6 is connected to the contact b. In this case, the output signal is appeared at the output of the delay circuit 2 from the preceding cell a to the defective cell b and the output signal of the succeeding cell c is appeared at the circuit 1. The output signals from the two cells preceding and succeeding to the defective cell b are replaced to the synthesized 3 signal, allowing to increase the video quality and the resolution.
