Abstract
Local color correction to color values which result from processing of images within a Color Management System (CMS) is implemented by adjusting existing fields and tags within a color profile. A source image is rendered on a source digital imaging device, and the same or a different image is manipulated by the CMS then rendered on a destination digital imaging device. The CMS uses predetermined color profiles associated with the source and destination devices. The technique is useful when the manipulated image rendered on the destination device has a number of color regions which the user determines are unacceptably different in appearance from the source rendered image. Depending upon the embodiment being practiced, either spectrophotometric or colorimetric measurements or onscreen identifications are made of the respective error regions within the two rendered images and the user is enabled to indicate preferred color matching results. Based upon these measurements and user input, the original profiles are modified to improve the CMS quality performance as judged by the user.
