THE INFLUENCE OF COLOR RENDERING CHARACTERISTICS TO THE TELEVISION PICTURE COLOR REPRODUCTION

摘要

The color rendering index (CRI) is a quantitative measure of the ability of a light source to reveal the colors of various objects faithfully in comparison with an ideal or natural light source. Meanwhile, strong reds are prevalent in skin tones and clothes, the appearance of which play an important role on visual environment quality, so the special color rendering index R9 is a critical factor influencing the television picture quality. In this research, we carried out subjective evaluation and objective measurement for the color difference of several visual targets between reference light source and tested light sources with different CRI, and the color reproduction of these targets' pictures taken under the above mentioned scenes were also appraised. The result of this research provides technical basis for the revision of < Standard for Lighting Design and Test of Sports Venues>.
