Colour monitors are widely used in today's computer systems. For many applications, such as those used in vision research, programs arc required to generate specific colours on the monitor. Unfortunately, monitors vary significantly in the colour characteristics of their phosphors and the amount of light emitted for a particular applied voltage. However, there exist reasonable models for characterizing the colour properties of monitors. Also, the International Commission of Light (CIE) has standardized on particular representations of colour to which display monitors can be calibrated.In this paper we report on experiments related to the task of reproducing colours, specified in CIE? terms, on the monitor. We evaluate a calibration method based on solving the colorimetric equation for each desired colour, which produces gun voltages by using a piccewise linear interpolation algorithm. The chromaticity of each phosphor is assumed to be constant as the applied voltage varies. A second model, which provides for chromaticities to vary with applied voltages is found to yield more accurate results than the first model. Systematically we study errors associated with the models and discuss possible origins of these errors, as related to the CRT monitor. A comparison of results for two similar CRT monitors is included.
