Visual characterization of color CRTs

An accurate and inexpensive method for calibrating computer displays is introduced. The characterization is done entirely by visual comparisons and the results are equivalent to characterizations made by commercially available instruments. The method is based on a parametric CRT model, requiring that the user perform only a limited number of comparisons.

Computer color reproduction

Computer based color imaging is rapidly moving from the realm of the specialist to the general public. To enable users the greatest benefit from advances in color image reproduction technology, the computer systems have to modify to incorporate this new technology. Two possible approaches are described - by the adoption of color management system software, and by the adoption of device independent color variables. Although both systems are likely to perform equally well when properly configured, the later is likely to be the long term choice as it will yield the most robust, lower cost and transparent system.
