The refractive lens surface may include a set of lens patches, each of which indexes a region on the source image to refract light from the indexed region to recreate a patch of the target image.

The solution may account for additional constraints imposed by the physical manufacturing procedure. Doing so results in a design for a refractive surface amenable to milling (or other manufacturing process).

The intermediate image is then compared to the grayscale reference image to generate the correction values. The lookup table may then be applied to a grayscale image that has been converted from the RGB color image.
