Claim Text:
1. A spectral synthesis module to generate color output signals in response to image capture device sensor outputs, the spectral synthesis module comprising: a linearization module to receive first, second, and third camera-processed device sensor outputs and generate first, second, and third linearized camera color values; a camera-color temperature module to receive the first, second, and third linearized camera color values and generate estimated first, second, and third raw color values; a processing module to divide the estimated second and third raw color values by a first scale factor (Σ) to generate first and second scaled color values (p,q), wherein the first scale factor is generated by adding together the estimated first, second, and third raw color values; a wavelength determination module to determine a first transition wavelength λ a mapping module to map the first and second scaled color values based on the first and second transition wavelengths, a transition scaling factor that extends the rectangular spectra representation for a general spectral representation of light, and a parameter that represents a low value for the rectangular spectra representation to determine a first set of color output values; a multiplier module to multiply the first set of color output signals with the first scale factor to output a second set of color output values; and an output module to output color output signals based on the color output values.
