52 | NEC DISPLAY WALL CALIBRATOR - USER’S GUIDE

This panel allows measurements of colors displayed on the screen

to be taken with the calibration sensor and the numerical results

are displayed.

To take color measurements using the Colorimeter, display a white

image on the screen to be measured and place the calibration

sensor on the screen. Then click the Measure button to take a

single color measurement and display the results.

The measurement results are shown in CIE xyY and Color

Temperature.

The Color Temperature eld shows the corresponding correlated

black body radiator temperature of the measurement in Kelvin. The

Δuv (Delta-uv) value indicates how far the measurement is from the blackbody radiator locus. The Kelvin value is

only meaningful for colors that are near the black body radiator locus, such as most shades of white.

This feature can be used together with the Test Patterns tool to verify the calibration accuracy of a display. In this

case the Calibrated White function in the Test Pattern panel can be used to show a calibrated white screen, then

the sensor can be used to measure the screen.

It can also be used to measure the native white point of a display by using the 100% White function in the Test

Pattern panel to show a native white screen, which can then be measured using the sensor.
