ABSTRACT:
An image pick-up apparatus comprises: an optical system for optically controlling incident light rays; an image pick-up device for converting the light rays to signal charges; a drive pulse generating circuit for outputting driving pulses in order to drive the image pick-up device; and a signal level detecting circuit. A voltage-controlled signal generating circuit is provided for maintaining the levels of the output signals of the image pick-up device at a constant level by controlling the driving pulses outputted from the drive pulse generating circuit in accordance with the levels of the output signals of the image pick-up device. According to the apparatus of the present invention, the structure becomes simple, miniaturization becomes possible, response speed becomes fast, and power consumption becomes negligible compared the conventional apparatus.
