Abstract
With the CCD imager of the present invention, signal charges from the image area are transferred by plural juxtaposed read-out registers. The storage region of the read-out registers, through which electrical charges are transmitted, is narrower in width at the image area side and broader in width at the other read-out register side. By virtue of such arrangement of the storage area, there is formed a potential which becomes shallow at the side of the image area and becomes deep at the side of the other read-out registers. By such potential, signal charge transfer efficiency between the read-out registers is improved.
