ABSTRACT:
A method and apparatus for compensating for deficiency in the illumination light from a light source is provided, where the spectrum in the visible range of light from the light source is determined, and a deficiency at a wavelength or band of wavelengths in the visible range of light is determined therefrom, a color sequencing device is provided having a set of filters comprising red, green and blue filter segments, and an additional color balancing filter segment, and wherein a the color balancing segment is constructed so as to preferentially pass a band or bands of wavelengths, which band or bands are determined based on the determined deficiency of the light source.
