Conclusion
These initial data show that a matrix transformation based on an (x, y, Y) difference metric may improve the calibration accuracy of a tristimulus colorimeter for these measurables (chromaticity and luminance), as compared to the current standard for display measurements. The data also show that the technique works well with other light sources.
While this work to date has produced a limited amount of data, the technique that motivated it is clearly shown to hold promise in some situations. More experiments are necessary using different colorimeters, displays, and other colored samples. It would be interesting to experiment with other difference metrics, such as those based on a uniform color space or standard color difference equations.
