ABSTRACT:
An automatic light level control system for a video camera is disclosed which uses a time-variable camera clock for determining and controlling the scanning rate of the camera. A control means responsive to the light level of the video output of the camera controls the rate of the camera clock, and thereby the scan rate of the camera so that the light level of the video output is maintained within desired limits.
