Abstract
A method and system is provided for driving a charge-coupled solid-state interline imaging device which removes smear components and dark current to prevent flicker in the imaging device. The drive method and apparatus controls the drive signals so that the transfer elements of the imaging device are uniform while an optical image is being exposed. Also, a dummy scanning transfer operation is performed to the vertical and horizontal charge transfer paths after the exposure. Furthermore, the potential levels of the vertical charge transfer paths may be set to an equal level. As a result, the smear components on the vertical charge transfer paths are uniform so that the flicker in the reproduced optical image is significantly reduced.
