User Manual

One part of CIE Color Apperance Model 02 (CIECAM02) is to take care
about the luminance of the ambient light of the room. The monitors
gradation curve can be optimized to the luminance of the rooms ambient
light to optimize the effective contrast ratio (combination monitor and
ambient light) by choosing on of the CIECAM02 setting.
The NEC recommends to use one of the following settings depending
on luminance of the ambient light of the room:

0 - 32 Lux:

CIECAM02 - dark

32 - 64 Lux:

CIECAM02 - dimmed

>= 64 Lux:

CIECAM02 - bright

The luminance and the white point of the ambient light of the room can
be measured with a measurement device which supports ambient light
measurements (e.g. basICColor SQUID 2 or X-Rite Eye-One pro).
