摘要： An analog signal photo-electrically converted in a pixel of a light receiving area is converted to a digital signal by an ADC. The digital signal is processed by a digital signal processing circuit, and then, successively output as a digital video signal. The digital signal processing circuit has a first signal processing block for detecting and correcting a pixel defect and preventing a noise, and a second signal processing block for restoring apparent resolution lost by the processing by the first signal processing block.
