Abstract
A solid state imaging device comprising a charged coupled device CCD for use in a camera which has a shutter and wherein the output of the charged coupled device is supplied to a video processing unit which drives a magnetic recorder for recording images on a magnetic medium and wherein first and second field images are simultaneously picked up by the photosensitive regions of the solid state image sensor when the shutter is opened and the first and second field signal charges are read out sequentially from the charge couple device when the shutter is closed. The invention also provides for sweeping unrequired charges from prior images from the charge coupled device so as to prevent blooming. The exposure on the charge coupled device automatically controls the time or aperture of the exposure system based on detected signals. The shutter is closed for two field periods while the first and second fields are read out so as to prevent smearing and mixing.
