Abstract
It is intended to obtain a high quality image which is not affected by the fluctuation of dark outputs, and pixels having a specifically large dark output, called defects, and has no lateral line etc. A solid-state image pickup apparatus including: an aperture pixel region which accumulates and outputs the electric charges generated depending on incident light; a light shielded optical black region; a black reference pixel region in which no impurity region for accumulating electric charges is formed; and level shifting means which shifts the reference level of the output signals of the black reference pixel region with respect to the reference levels of the output signals of the aperture pixel region and the optical black region, is provided.
