Abstract
A method of correcting an optical axis of a zoom lens includes obtaining a degree of optical axis misalignment corresponding to a current zoom lens state of a camera, considering the current zoom lens state of the camera and data previously stored to define a relationship between a state of the zoom lens of the camera and the degree of optical axis misalignment, determining digital zoom information to compensate for the degree of optical axis misalignment, considering the degree of optical axis misalignment, and generating correction image data by cropping and magnifying image data photographed by the camera to correspond to the digital zoom information.
