7 Optimising the image
The projector has powerful features for picture optimization. This chapter describes details in
using these features. All color calibration is done using Barco’s proprietary RealColor™ solu-
tion.
7.1 Calibration data
All Barco projectors are measured and calibrated with high precision equipment at the factory
for the best out-of-box experience. Over the lifetime of the lamps the characteristics of the
projector might change slightly. The same applies when replacing lamps.
7.1.1 Updating RealColor™ calibration data
For accurate results with the RealColor™ system, accurate measurement data is required.
RealColor™ calibration data can be found under the menu entry PICTURE >REALCOLOR
>REALCOLOR CALIBRATION > MEASURED VALUES X/Y and relative luminance values
for red, green, blue, white and BrilliantColor™ 1 are entered in this menu. The BrilliantColor™
should all be set to 0.000 for the VizSim (RGB) color wheel. All values can also be updated
using the communications protocol over RS-232 or LAN.
Before setting these values, it is important to select the desired BrilliantColor™
setting. Go to menu entry PICTURE > REALCOLOR > BRILLIANTCOLOR to select
the desired BrilliantColor™ look.
Measurements must be done on the built in test patterns. This is in particularly important for
the BrilliantColor™ 1 test pattern since it is impossible to generate this pattern correctly using
a computer source. In the user menu these patterns can be accessed through PICTURE >
CALIBRATION > REALCOLOR CALIBRATION > COLOR CALIBRATION TESTIMAGE/
COLOR PROCESSED TEST IMAGE.

Performing a factory reset of the projector will restore the measured values to the
values measured in the factory.
When measuring data, a high quality measurement instrument is highly recommended
for accurate results. Spectrometers (like PhotoResearch PR-655) are preferred.
