Abstract
A circuit for controlling the speed of an electronic shutter for a video camera using a CCD comprises a light intensity detector, a first generator, a second generator, and a comparator/controller, wherein the electronic shutter speed is controlled by adaptively varying a duration of the light storage of the CCD for every vertical period in response to a light intensity of an object.
