Abstract: An embodiment of a method for compensating variations in an attenuation of light of an optical filter of a light sensor system comprises illuminating a clear sensor and a color sensor of the light sensor system with a test light having a test spectrum. Therein the color sensor comprises the optical filter and is designed to predominantly sense light with a wavelength within a pass band of the filter; and the test spectrum has components outside the pass band. A clear test signal generated by the clear sensor and a color test signal generated by the color sensor are received in particular in response to the illumination with the test light. 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 to compensate the variations in the attenuation of light based on the first transmission value T and a nominal transmission value Tn of the filter.
