Paper Abstract

We present a new CRT characterization technique that improves the accuracy of the characterization. This is achieved by optimizing the linear transformation matrix of the two stage model in the uniform CIE/L*a*b* space. We also introduce an approach to improve the characterization performance for low luminance colors. These methods are used to calibrate two CRT monitors and better accuracies are obtained compared to existing methods, especially for low luminance colors. We present a systematic way to adjust the white point of the monitor using hardware settings. This allows us to adjust the monitor white accurately without losing any digital counts which is the case if a software approach is used. We propose a novel search algorithm to achieve very high accuracy calibration for experiments where a limited number of colors has to be displayed. We apply this search algorithm to the case of monochrome image display application and verify the performance our method.
