Abstract
One aspect of the invention is a method for altering defects in a digital image. At least a first pixel of a first channel of a digital image is filtered using digital circuitry to produce a filtered pixel by averaging the intensity of the first pixel and a plurality of additional pixels in the neighborhood of the first pixel. At least one of the pixels is weighted in response to the intensity value of at least one pixel in a defect channel associated with the digital image. A corrected digital image is produced using the digital circuitry in response to the filtered pixel and the first channel of the digital image.
