ABSTRACT:
A color correction method utilizes a specially designed, perceptually ordered, intermediate color space and color value information from an original source device image and color value information from a repositioned source device image to quantify the accuracy of a color image translation process. The color correction method operates, under user control, to convert original source device image color values to intermediate space color values, where the color values can be analyzed to determine whether or not all of them are positioned within the gamut of a target device. If all of the original source device color values are not positioned within the gamut of the target device, the user can reposition these colors so that all or substantially all of the color values are contained within the gamut of the target device. After the color values are repositioned, an aggregate image closeness term and a proportion conservation term are calculated and the sum of these two terms is a scalar quantity equivalent to the accuracy of the image translation process.
