Digital photofinishing system including scene balance and image sharpening digital image processing

摘要

A method of digital photofinishing comprising the steps of: producing a digital color image in optical printing densities of a color image captured on photographic media; processing the digital color image with a scene balance algorithm to produce a balanced digital color image; mapping the balanced digital color image through a hard copy media characteristic curve to produce a balanced digital color image mapped to print densities of the hard copy media; sharpening the mapped balanced digital color image with a sharpening algorithm optimized to avoid unacceptable artifacts; and digitally printing the sharpened digital color image in hard copy media.
