A New Color Breakup Measure Based on Color Difference Between Fields and Contrast to the Surrounding

Abstract

Field-sequential-color displays can have low power consumption and high spatial resolution, but can suffer from annoying color breakup. Various approaches to suppress color breakup have been presented in recent literature. However, a suitable color breakup measure is necessary to compare the performances of those approaches, and is also helpful for quick evaluation of algorithms and parameter settings. A perception experiment was carried out to investigate the perceived color breakup with different field color combinations, different light intensities, and different backgrounds. The results indicate that the color difference and the relative contrast between fields have a significant effect on the perceived color breakup, rather than the absolute luminance value, which is different from existing metrics for color breakup visibility. Based on this new insight, a computational metric for color breakup visibility is proposed and discussed, which has a high correlation with the subjective scores (R2 = 0.945).
