Abstract
An image sensor includes charge storage regions which gradually store charges corresponding to the amount of light received, a plurality of image transfer elements which gradually transfer the charges, and transfer gates which transfer the charges in the charge storage regions to the charge transfer elements. The image sensor provides further a device which changes an electric potential of an electrode of the charge storage regions in accordance with the amount stored of the charges, and a device which detects the electric potential of the electrode and outputs the detected electric potential as a switchover timing control signal of the transfer gates.
