Electronic correction
The electronic correction adapts the native color gamut towards the desired (target) color gamut (e.g. DC28_
DCI_Xenon.TCGD). This correction is introduced by the DMD drivers and is also called ‘P7 correction’. The
electronic correction takes place once the MCGD file of the projector is mapped with the TCGD file of the film.
Influence of aspect ratio
The aspect ratio of the projected image could have a small influence upon the measured xy coordinates.
Therefore, it's recommended to save the xy coordinates per aspect ratio in separate MCGD files.
CAUTION:
Prior to start with color gamut calibration ensure that the white point calibration is
finalized successfully. See
“White point calibration”, page 123
Color gamut calibration procedure
1.
Check if the white point calibration is done. If not, see
“White point calibration”, page 123
2.
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.
3.
Select the appropriate lens file (2D or 3D). See projector user guide for more info on lens files.
4.
Sequentially measure and enter the xy coordinates
of the three primary colors (red, green, blue) and
full white. To do so, use Web Communicator and browse to:
Installation
>
Color calibration
>
Projector
color
. For detailed instructions see projector user guide.
Caution:
In case of 3D, measure the xy coordinates once through the left eye glass of the 3D
goggles and once through the right eye glass.
5.
Once all xy coordinates are measured and entered proceed by saving all measured values into a MCGD
file.
Tip:
Put in the MCGD file name the type of projection mode (2D or External 3D) and the aspect
ratio (FLAT, SCOPE).
6.
In addition you can check if the corrected colors comply. To do so, browse to the Web Communicator and
navigate to
Configuration
>
Color calibration
>
Verify corrected colors
. See the projector user guide for
detailed instructions.
