Claim One:
1. A spectral synthesis module to generate color output signals in response to image capture device sensor outputs, the spectral synthesis module comprising: an input module to receive image capture device sensor outputs ( 1515 A); the image capture device sensor outputs being a result of an input spectrum of an image being applied to corresponding image capture device spectral sensitivities of an image capture device ( 1710 ); a processing module ( 1500 E) to divide two of the image capture device sensor outputs by a first scale factor (Σ); wherein the first scale factor comprises the sum of all of the image capture device sensor outputs; a first two-dimensional look-up table (2-D LUT) ( 1510 C) to map results of the dividing to determine a first wavelength and a second wavelength; wherein the first wavelength comprises a wavelength where a substantially rectangular spectral representation transitions from zero to a second scale factor (I) and the second wavelength comprises a wavelength where the substantially rectangular spectral representation transitions from the second scale factor value to zero; wherein the second scale factor comprises a ratio of the first scale factor divided by a circular integral of the sum of the image capture device spectral sensitivities of the image capture device ( 1710 ); a second 2-D LUT ( 1510 E) to map the first wavelength and the second wavelength to a first set of color output signals; and a multiplier ( 1540 E) to multiply the first set of color output signals with the first scale factor to output a second set of color output signals.
