Abstract
PURPOSE:To extract the output signal of an image sensor from a signal processing circuit faithfully and stably, by integrating the output signal of the image sensor for every bit and by sample-holding this output signal to convert it into an analogue signal. CONSTITUTION:Clear pulse phiC is led into integrating circuit 12 from driving pulse generating circuit 11 simultaneously with inputting of the output signal of CCD-system image sensor 10 into integrating circuit 12, and the peak value for every bit of the output signal which is output from the image sensor is held. Sampling pulse phiS is led into sample hold circuit 13 simultaneously with inputting of the signal, which is integrated for every bit by integrating circuit 12, into sampling hold circuit 13. The timing of sampling pulse phiS is shifted from that of clear pulse phiC and is set to a time when the integral value is stable completely, and thus, the signal including no spike-form noise is output from sample hold circuit 13.
