An image-pickup apparatus configured to perform vertical-dark-shading correction with increased precision independently of photographing conditions and/or a photographing environment is provided. The image-pickup apparatus includes an image-pickup element having an effective-pixel part including plural pixel parts which are not shielded from light and a light-shielding-pixel part including plural pixel parts shielded from light, a signal-processing unit configured to set the reference level of output signals transmitted from the effective-pixel part, and a control unit configured to switch between plural areas used to set the reference level, the areas being provided in the light-shielding-pixel part, based on the photographing conditions and/or environmental conditions.
