Paper Abstract

The relationship between input DAC count and output luminance in CRT display varies according to the brightness control. In this study the effect of brightness adjustment on the accuracy of color reproduction in CRT display is shown experimentally. The optimum brightness level of test monitor has been measured by using a device developed in our laboratory. The accuracy of the simplified color reproduction model is evaluated for three monitor setups, which is controlled to optimum, low, and high brightness level. To prove the experimental results, the channel additivity and chromaticity constancy assumptions are tested for three setups. With the color difference between predicted and measured values for 215 colors, it can be ascertained that the brightness must be adjusted to optimum level to enhance the accuracy.
