Abstract
A solid-state image sensing apparatus of an aspect of this invention can appropriately correct the black level of a video signal even when a high-luminance state or spotlight exists. The apparatus includes an effective pixel unit to receive object light, and a light-shielded light-shielded pixel unit to output an optical black level equivalent signal. In addition to the output from the effective pixel unit, one of the output from the light-shielded pixel unit and a predetermined reference voltage is selectively output.
