Abstract:
A method for automatically compensating for scanner metamerism errors associated with scanning input images using a digital color image scanner, wherein the input images can be on a variety of different input media having colorants with different spectral characteristics, comprising scanning an input image on a digital color image scanner to produce a scanned image; determining one or more estimated color balance error values in a color balance parameter space by analyzing the scanned image using a color balance analysis algorithm; assigning an input medium from a set of possible input media for the scanned input image in response to the estimated color balance error values; selecting a scanner metamerism correction color transform associated with the assigned input medium; and applying the selected scanner metamerism correction color transform to the scanned image to produce a corrected image compensated for scanner metamerism errors.
