7.2 Setting a white point or color temperature
After enabling ColorMax set the color temperature in the menu PICTURE >
COLORMAX > COLOR TEMPERATURE
. Values between 3200K and 9300K
can be selected. These color temperatures are tracking the “black body curve”-
the black curved line in the center of CIE Chart in Figure 7-7. The default is the
D65 illuminant at 6500K.
The white point can also be set to a custom value defined by an x, y coordinate
not linked to the black body. Go to menu
PICTURE > COLORMAX > X-COOR-
DINATE and PICTURE > COLORMAX > Y-COORDINATE to change the white
point.
7.2.1 Defining the system color gamut
All colors visible to the eye are defined by CIE Chart in Figure Figure 7-1. The boundary of the
colors the projector can display is called the system color gamut. The white triangle in the
figure is an example of a system color gamut. By default the projector has the widest pos-
sible system gamut.
The system color gamut cannot be expanded outside native color gamut.
It may be desirable to change the system color gamut of the projector to:
• Color-match multiple projectors.
• Meet defined color standards, like REC 709.
• Create a special “look” to the image.
Before the system color gamut can be changed, the desired ColorMax mode has to be
defined. To change the ColorMax mode please go the menu
PICTURE > COLORMAX >
DESIRED VALUES > DESIRED COORDS MODE .
ColorMax has to be enabled for the desired system gamut to be applied. Go to menu PIC-
TURE > COLORMAX > COLOR CORRECTION
to enable ColorMax.
After ColorMax is enabled and the desired color correction mode is selected, please go the
menu entry
PICTURE > COLORMAX > DESIRED VALUES to change the color points to
your desired system color gamut.
