ABSTRACT:
An electronic still camera incorporating a base clip circuit for clipping an image signal at a base level. In order to eliminate a reduction in the S/N ratio of the image signal attributable to an increase in the dark current level in pixel signal, the clipping level of the base clip circuit is variable in accordance with, for example, the shutter speed.
