  • Spectral normalization using illuminant exposure estimation
    Patent number: 7421121
    Abstract: After image capture, scene parameters are analyzed, e.g. lux, flicker, or world estimation. A best guess illuminant for the scene parameters is determined. At this point, the white balancing coefficients corresponding to that illuminant may be applied.
    Type: Grant
