ABSTRACT:
An apparatus and method for estimating the power spectral density of an unknown illuminant that does not require direct spectral measurements. The apparatus and method allows calibration of color images taken with commercially available digital cameras in arbitrary illumination. Besides an imaging system, a digital computer, a means for transferring image information from the imaging system to the digital computer, and software to carry out the method, the only additional equipment a photographer needs is a set of color standards.
