Abstract

Several color dif ference models have been specified by CIE, and amongst them the CIE 1976 L*a*b*model is widely used in various industry applications for its simplicity. However, it should be needed to investigate the underlying parameters, such as quantization bit depth and gamma value, for emerging high quality imaging systems by means of the newer CIEDE2000 mode. This paper comparatively discusses the required bit depth for digital cinema applications using the both of CIE 1976 L*a*b*and CIEDE2000 color models. The simulation results show that the required bit depths obtained from these two color difference models approximately coincide with each other, so that the design method proposed by the authors with CIE 1976 L*a*b*model enables to predict the required bit depth for high quality imaging systems in a simple manner.
