Abstract:
1. A computer-implemented method of adjusting at least one color of at least one first object in a digital image comprising: a) providing the image containing the object and determining the chrominance values of the first object in the image; b) providing a reference data set comprising an illumination-dependent color of the first object that represents the color of the first object under a desired illumination condition; c) adjusting the chrominance values of the first object in the image using the reference data set to provide a different desired color of the first object in the image that represents the color of the first object under the desired illumination condition, and wherein the image includes at least a second object in the image, and the image comprises pixels and the method further comprises adjusting all pixels in the image that have chrominance values similar to the chrominance values of the first object prior to chrominance adjustment, such that their adjusted chrominance values are substantially the same as those of the pixels corresponding to the first object after chrominance adjustment.
