Spatial Color Confidence for Physically Based Rendering Settings on Lc Displays

Abstract

Color confidence is crucial regarding physically-based rendering settings in order to produce most promising visual results. Display characterization and in particular spatial inhomogeneity correction is often neglected in physically-based rendering applications, yet, are important to achieve color confidence. By evaluating relevant display characteristics, this paper recommends a strategy for selecting the most suitable characterization model for a given device. We indicate the importance of correcting spatial inhomogeneity and, on that account, provide an extension to the applied characterization models. All characterization models as well as our proposed extensions are implemented using modern graphics hardware, therefore, applicable to real time applications. The focus is on finding an optimal characterization model which can achieve color confidence across the display while reducing characterization time and effort. All models are created using a common, single point, consumer measurement device and applied to two LC displays.
