Method, apparatus, and computer program for correcting optical axis of zoom lens

An apparatus for correcting an optical axis of a zoom lens, the apparatus comprising:

• a correction data generation unit configured to obtain 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, and determine digital zoom information to compensate for the degree of optical axis misalignment, considering the degree of optical axis misalignment corresponding to a current zoom lens state of the camera;
• and
• an image data output unit configured to generate correction image data by cropping and magnifying image data photographed by the camera to correspond to the digital zoom information.
