ABSTRACT:
A method and a color rendering filter for compensating for deficiency in illumination light from a light source in display systems are provided. The color rendering filter has a color that is determined based upon the spectrum, sensitivity of viewer's eyes over the visible light range, and a pre-determined waveband threshold.
