Abstract
A CCD imager includes a CCD from which a video signal added with a smear signal and the smear signal itself are produced. Using a subtracter, the smear signal is removed from the video signal from CCD. When the video signal from CCD exceeds a predetermined level indicating that the charge accumulated in the CCD is regulated to the maximum available voltage with the excess charge being drained away, the video signal from the CCD before being subtracted is selected. Accordingly, an image having no undesirable dark spot within the bright area can be reproduced.
