Title: An accurate characterization of CRT monitor (II) proposal for an extension to CIE method and its verification
Author: Katoh, Naoya; Deguchi, Tatsuya; Berns, Roy
Abstract: According to the ICC specification that is widely used for storing colorimetric characteristics of imaging devices for the current color management systems (CMSs), CRT monitor characteristics can be described by the tone reproduction curves (TRCs) of the red, green and blue channels and a transformation matrix from linearized RGB values to tristimulus values. This idea is based on CIE Technical Report 122#x2013;1996: #x201C;The Relationship between Digital and Colorimetric Data for Computer-Controlled CRT Displays,#x201D; which resulted from the research by Berns et al. This method produces very accurate results under normal conditions. However, users often change the settings of contrast or brightness knobs to a different position from the factory default adjustments. For some of these cases, the characterization method described in the CIE 122 does not produce accurate results. In this paper, we propose an extension to the CIE method for such cases. We investigated the effect of user controls on CRT monitor characteristics at various settings, and verified that our method produced accurate results under any conditions.
