Abstract

An image pickup apparatus is disclosed which is provided with a distortional-aberration memorizing element for memorizing distortional-aberration information about an objective lens, a state-of-objective-lens detecting circuit for detecting a state of the objective lens, an image correcting circuit for reading out distortional-aberration information about distortional aberration occurring during photography from the distortional-aberration memorizing element on the basis of information supplied from the state-of-objective-lens detecting circuit, and electrically correcting a distortion of an image due to the objective lens with a predetermined image height in a photographed image selected as a datum.
