1. A method for vignetting correction on an image, performed in an apparatus for correcting vignetting effects of the image, the method comprising: receiving a two-dimensional (2D) image; calculating a radial bright channel representing intensity of the 2D image; estimating a vignetting function of the 2D image having similarity to the calculated radial bright channel; and correcting the vignetting effects of the 2D image by using the estimated vignetting function.
