15.1 Calibration process
Overview
1.
Select the desired aspect ratio by activating the correct lens file.
•
SCOPE
format
•
FLAT
format
2.
Laser white point calibration
.
3.
The Communicator contains a wizard for white point calibration. See user guide of the Communicator for
detailed menu navigation instructions.
4.
Color gamut calibration
. (electronic P7 correction). Measured values are saved in the Measured Color
Gamut Data (MCGD) file. Needs to be done per format and per projection mode.
•
2D
•
External 3D
5.
Select target colors
. 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.
6.
For more info about color gamut calibration see
“
, page 173. The Communicator
software contains a wizard for color gamut calibration. See user guide of the Communicator for detailed menu
navigation instructions.
7.
Verify corrected colors
.
8.
For detailed instructions on how to verify corrected colors see user guide of Communicator.
9.
Arrange calibration files in macro
. To apply correct color calibration it is important that the MCGD file(s) and
matching TCGD 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:
1.
First activate the
INPUT
file.
2.
then activate the
PCF
file (PCF already contains plane 1 information),
3.
then activate the
MCGD
and
TCGD
files.
10.
For detailed instructions on how to create a macro see Communicator's user guide.
15.2 White point calibration
About white point calibration
White point calibration should be executed to correct a color shift during dimming. The white point will be
stabilized over the full dimming range.
Required tools
•
Spectroradiometer.
•
Communicator software.
Preparations
1.
Setup the ambient light conditions
as it should be during the play out of the movie. (e.g. only the stairs and
emergency exit lighting is switched on).
Note:
In an optimal setup less than 1% of light from any other source than the light from the projector
should illuminate the screen.
2.
Configure the desired aspect ratio: e.g. FLAT or SCOPE (use most common aspect ratio). Do this by activating
the correct LENS file.
3.
Position the spectrometer perpendicular to the screen and measure in the center of the screen.
4.
Start up Communicator and follow the laser white point calibration wizard.
