Exact Characterization of Monitor’ Color Showing

In order to effectively control a monitor's color showing, the key technique is to establish the relationship between RGB data and their corresponding CIE colorimetric values. But in nowadays ICC color management system, there is no the relation between RGB and color's absolute CIE colorimetric value for monitor. In our study, the CIEXYZ values of a monitor's colors were firstly matched to their CIELab data under its white point, and then a relationship between RGB and CIELab data was built by using the technique of characterizing a RGB output device in ICC system. Experiment was carried out on a popular LCD monitor under three different surrounding lights, and the results showed that the mean color different of forecasted colors were all less than 1, and all the maximal color differents were less than 2 in experimental surrounding lights. And in case of color forecasting from desired CIELabs to actual CIElabs, the results were less 2 and 6 respectively. The method developed this study could be used in controlling the absolute colorimetric colors on a monitor.
