ABSTRACT:
A method of correcting image distortion and an apparatus for processing an image using the method are provided, where the method can overcome the disadvantages of the conventional methods of correcting lens distortion and can minimize image quality degradation at outer portions,. The method includes: receiving an image from a wide-angle lens; extracting a distortion coefficient of the distortion in the image caused by the wide-angle lens; correcting the distortion of the image by using the extracted distortion coefficient; and displaying a corrected image. The apparatus includes: a wide-angle lens for receiving an image; an image processing unit comprising a distortion coefficient extracting unit for extracting a distortion coefficient of distortion in the image caused by the wide-angle lens and a distortion correcting unit for correcting the distortion of the image using the extracted distortion coefficient; and a display unit for displaying a corrected image.
