Abstract: The wide-gamut system colorimetry for ultra-high definition television (UHDTV) specified in Recommendation ITU-R BT.2020 covers most real object colors. This paper introduces some practical spectral sensitivity curves for the wide-gamut system colorimetry, which is designed to approximate the ideal camera spectral sensitivity curves. The accuracy of color reproduction with such spectral sensitivity curves is demonstrated by computer simulation with a comprehensive database of natural object colors. Also, the accuracy of the color reproduction of a real UHDTV camera equipped with a newly developed dichroic prism is demonstrated.
