We selected appropriate indices for color rendition and determined their recommended values for ultra-high-definition television (UHDTV) production using white LED lighting. Since the spectral sensitivities of UHDTV cameras can be designed to approximate the ideal spectral sensitivities of UHDTV colorimetry, they have more accurate color reproduction than HDTV cameras, and thus the color-rendering properties of the lighting are critical. Comparing images taken under white LEDs with conventional color rendering indices (Ra, R9-14) and recently proposed methods for evaluating color rendition of CQS, TM-30, Qa, and SSI, we found the combination of Ra and R9 appropriate. For white LED lighting, Ra ≥ 90 and R9 ≥ 80 are recommended for UHDTV production.
