An embodiment of a method for processing light sensor signals comprises illuminating a clear sensor (CS) and a color sensor (RS, GS, BS) of a light sensor system with a test light having a test spectrum. Therein the color sensor (RS, GS, BS) comprises an optical filter and is designed to sense light with a wavelength within a pass band of the filter and the test spectrum has components outside of the pass band. A clear test signal which is generated by the clear sensor (CS) and a color test signal which is generated by the color sensor (RS, GS, BS) are received. Then a first transmission value (T) is determined based on the clear test signal and on the color test signal. Finally, a compensation factor (Kr, Kg, Kb) is calculated based on the first transmission value (T) and on a nominal transmission value (Tn) of the filter. |
