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.

Use the arrow keys to cycle through the images.

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.
