Abstract
Reducing or eliminated color-dependent vignetting in a digital camera includes: providing, for each color that said camera can image, a raw array of data corresponding to a desired scene; and changing the raw arrays such that the array for each color exhibits substantially the same amount of vignetting so as to reduce color-dependent vignetting in a composite image based upon each of the changed arrays.
