Abstract:
1. A method for removing color fringe in a digital image, comprising: obtaining a digital image; forming a variable-size image by reducing the digital image; performing detection of color fringe on the digital image, so as to find pixels with color fringe in the digital image, set each of the found pixels with color fringe as a color fringe pixel, and generate a color fringe map corresponding to the digital image according to a position of the color fringe pixel in the digital image; performing detection of color fringe on the variable-size image, so as to find pixels with color fringe in the variable-size image, set each of the found pixels with color fringe as a color fringe pixel, and generate a color fringe map corresponding to the variable-size image according to a position of the color fringe pixel in the variable-size image; correcting the color fringe pixel in the digital image through a correction procedure, so as to obtain the corrected digital image; correcting the color fringe pixel in the variable-size image through a correction procedure, so as to obtain the corrected variable-size image; enlarging the corrected variable-size image and the color fringe map corresponding to the variable-size image, so that the corrected variable-size image and the color fringe map corresponding to the variable-size image have the same resolution as the digital image; and blending the corrected digital image and the enlarged corrected variable-size image according to the color fringe map corresponding to the digital image and the enlarged color fringe map corresponding to the variable-size image.
