16. Color calibration
16. C OLOR CALIBR ATION
About this chapter
This chapter describes the luminance and color calibration process for the DPxK-B LP series. Where applicable r eferences are m ade
to the u ser guide of the Communicator for detailed menu navigation instructions. T he first chapter describes the complete calibration
process in chronological order.
Color calibration should be executed during the installation o f the p rojector and also after some
service ac-
tions as mentioned in the service manual.
Overview
• Calibration process
• White point calibration
• Color g amut calibration
16.1 Calibration process
Overview
1. S elect the desired a spect ratio by activating the correct lens file.
- SCOPE format
- FLAT format
2. L aser white p oint calibration.
The Co mm unicator contains a wizar d for white point calibration. S ee user guide of the Com municator for detailed menu naviga-
tion instructions.
3. Color ga mut calibration. (electronic P7 correction). Measured values are saved in the Measured Color Gamut Data (MC GD )
file. Ne eds to be done per format and per projection mode.
-2D
- External 3D
4. S elect target co lors. The target colors are stored in the Target Color Gamut Data (TCGD) file. Several TCGD files are already
available in the file system of the projector.
For more info about color gamut calibration see " Color gamut calibration", page 156. The Com munic ator software contains a
wizard for color gamut calibration. See user guide of the Com munic ator for detailed menu navigation instructions.
5. Verify corrected c olors.
For detailed instructions on how to verify corrected colors see user guide of Communicator.
6. Arrange calibration files in macro. To apply correct color calibration it is important that the MCGD file(s) and matching T CG D
file(s) are activated after that the INPUT file and PCF file are activated. For that it is recommended to create a macro where the
files are loaded one by one in the right order:
a) First activate the INPUT file.
b) then activate the PCF file (PC F already contains plane 1 information),
c) then activate the MCGD and TCGD files.
For detailed instructions on how to create a macro see Communicator ’s user guide.
16.2 White point calibration
About white point calibration
White point c alibration should be executed to c orrect a color shift during dimming. The white point will be stabilized over the full
dimming range.
Necessary tools
• Spectroradiometer.
• Communicator software.
