10.1 Color temperature
10.1.1 Color temperatures in greyscale mode reproduction
Color temperatures in greyscale mode reproduction
Beside the standard projection color temperature Video (6500K), computer (9300K) and full white, 2
additional medical related color temperatures are added:
• Clearbase
CIE graph coordinates: x = 0.28 ; y = 0.304
• Bluebase
CIE graph coordinates: x = 0.25 ; y = 0.305
Since the projector is operating most of the time in greyscale mode meaning a B/W signal is to be reproduced, the color temperature
setting can be seen as an adjustment of the neutral greyscale color temperature.
These 2 predefined color temperatures (as well as Full White ) are used to form, in combination with a display function, a preset for
greyscale reproduction.
That way, 6 presets are defined and can be selected by the user through the projector menu or remotely by the MediCal
®
Pro (in
case of a Barco DICOM Theatre system)
10.1.2 Color temperature in a standalone projector setup
Color temperature setting
In a standalone or open loop system i.e. without any feedback from the screen, the color temperature is defined by the user via the
OSD of the projector. The selected color temperature is then the value as it was set in the factory.
Factory settings are “dark room” settings meaning they do not take account of environmental conditions (am-
bient light, glare,...).

lone setup) ?
