Abstract:
An image pickup apparatus includes: a zoom lens; an image pickup element having an image pickup surface which receives an image which has been formed by the zoom lens, and converts to an electric signal; a shading correction parameter storage section which stores a shading correction parameter which differs at a front-surface side and a rear-surface side with respect to a center of an image, which is for correcting asymmetric shading at the front-surface side and the rear-surface side of the zoom lens; and a shading correction section which carries out correction operation of an image which has been picked up by the image pickup element, based on the shading correction parameter of the shading correction parameter storage section. When an object having a uniform brightness is captured, at any state from the wide angle end to the telephoto end, the zoom lens satisfies conditional expression (A).
