Abstract:
1. A computer-implemented method, comprising: controlling a digital device to capture two or more characteristic data arrays from light sensors in the digital device in response to the digital device being exposed to two or more light stimuli provided by a multi-spectral reference display, where the wavelengths of the light in the two or more light stimuli are known, and where a characteristic data array comprises an image produced by the digital device that includes data from at least two sample positions in a light stimulus; controlling a calibration logic to calculate spatially varying spectral response calibration data, the calibration logic to manipulate characteristic data arrays to produce spatially varying spectral response calibration data as a function of a comparison between characteristic data arrays and known wavelengths of the light in light stimuli, wherein the spatially varying spectral response calibration data includes spectral response calibration data for each of the at least two sample positions; and performing one or more of, providing the spatially varying spectral response calibration data to a correction process, controlling a correction process based, at least in part, on the spatially varying spectral response calibration data, storing the spatially varying spectral response calibration data in a storage device, and displaying the spatially varying spectral response calibration data.
