Abstract
A proposition is to provide a distortion correcting method, a carrier medium carrying distortion correcting program and an optical apparatus which can perform reliable and good distortion correction while suppressing the quantity of information in distortion correcting information. The distortion correcting method includes a preparing operation which expresses distortion aberration of an optical system for shooting in a function of a lens position thereof, optimizes coefficients of the function so that residual aberrations in two or more lens positions are controlled appropriately respectively, and prepares, in advance, information of optimized coefficients thereof as distortion correcting information of the optical system, and a correcting operation which performs a correction of distortion of an image picked up by the optical system based on the lens position at shooting time and the distortion correcting information prepared.
