Generating RGB signals from continuous spectral data requires only weighting the photon count at each wavelength by the amplitudes of the tristimulus curves at that wavelength and then summing over all wavelengths for each of the three tristimulus curves. Noise is increased when the conversion from the sensor signal to a standard color space requires the use of negative numbers in the matrix. There are no negative numbers in the process required here.<br /><br />That is one of the reasons a sensor like this would be nice to have.
