Abstract

PURPOSE: To keep the video signal output within a given range even when the amount of incident light is varied, while keeping the scanning frequency, by controlling only the number of continuous pick up number of video signal.
CONSTITUTION: The unit provides the image sensor 2 using CCD outputting the signal proportional to the amount of incident light via the optical system 1, and the average value detection circuit 5 detecting the average value of the output signal of the sensor 2, and the pulse generating circuit 6 converting the output of the circuit 5 into time width, controlling the number of continuous picking up of the output signal of the sensor 2 and varying the time for charge storage of the sensor 2. For example, as the amount of incident light is increased, the number of picking up times of video signal is increased, preventing the leakage of charge between electrodes by discharge of unnecessary charge of CCD. As a result, the output of the video signal from the mixer 13 can be kept constant for the given range.
