Abstract:
1. A method for transforming light intensities measured by a sensor for a portion of a graphical image into a device-independent representation of color for the image portion, the method comprising the steps of: receiving by a processor an output signal from the sensor indicative of a light intensity for the image portion for each of a plurality of hyperspectral bandpasses, wherein the plurality of hyperspectral bandpasses define a spectrum characterized by wavelengths ranging continuously between 360 and 830 nanometers, and wherein the component beam for each hyperspectral bandpass is characterized by a substantially unique and non-overlapping selection of continuous wavelengths from the spectrum; converting each of the output signals for the plurality of hyperspectral bandpasses into a raw count digital data (RCT calculating by another processor a relative normalized intensity value (T storing the T calculating bandpass delineated intermediate values (T calculating bandpass delineated sum values (ΣT calculating tristimulus values (X, Y, Z) for the image portion respectively as kΣT storing the tristimulus values (X, Y, Z) for the image.
