ABSTRACT:
In a color image transformation method and system, a photographic color-positive transparency media bearing a captured image is transmission scanned to provide a scanned image. The scanned image has an overall cyan-blue color balance and has grayscale mistracking relative to colorimetric chromaticity. The scanned image is automatically transformed to intermediary color image data encoding values. Both the overall cyan-blue color balance and the mistracking are corrected during the transforming.
