Abstract

The white point characterization of display images reaches new interest due to the widespread application of computer image processing and electronic printing. Some years ago it was the general consensus that the maximum composite signal of the red, green and blue channels should be used as the white point of the display. In characterizing this white point the concept of correlated color temperature is used, based on the outdated u,v-diagram. An experiment was conducted to investigate the appropriateness of the concept of the correlated color temperature. Experiments showed that a color difference in CIELUV color space is a better descriptor of correlated color temperature than the traditional method. It is recommended that for evaluating the correlated color temperature of computer screens and for comparing the white point of the screen with that of input pictures and printed outputs the new concept of minimum color difference in CIELUV color space be used.
