2.13 Calibrating the CP2000-XB System
NOTE
: DCP Librarian described here is licensed software intended for Christie installers only. Many of its
functions are now available at the TPC.
DCP Librarian
is a comprehensive Windows

-based software application used for calibrating image color
performance and defining electronic screen masking required in your particular installation, and for creating
individual
Projector Configuration Files (PCFs) and specific source files necessary for proper display of
incoming material. DCP Librarian also defines the system/network configuration for communication links to
the projector, transmitting information to and from the CP2000-XB via an Ethernet or RS-232 connection.
Chief functions, many of which can be done at the TPC, are introduced below.
Color Calibration
After the CP2000-XB is installed and all components are mechanically aligned for optimized light output and
geometry at the screen, its electronic system processing must be calibrated to ensure accurate color display in
the new environment. In this one-time global calibration, the installer measures initial colors at the screen and
enters this data—called Measured Color Gamut Data —into Windows

-based DCP Librarian software
installed on a laptop. The software then calculates precise corrections needed for regaining the desired color
performance—called
Target Color Gamut Data —and essentially compensates for the type of port window (if
present), screen, lens, light output, ambient light and other current environmental factors that affect color
performance. Results are defined in a file, activated, and downloaded to projector memory to be used as a basis
for all future displays.
If there are changes to the environment in the future (for example, a new screen is installed), the
CP2000-XB
should be re-calibrated. Also note that correction for proper color balance sometimes reduces overall light
output.
NOTE
: Most gamut functions are also now available in the TPC Gamut menu (password required).
Multiple MCGD files can be saved for use in different situations, such as when an anamorphic lens is swapped
on and off the projector.
Electronic Screen Masking
DCP Librarian also provides a powerful masking tool for precision cropping of the image to correct for
geometry problems such as a keystoned image. The effect is similar to aperture plate filing typically done for
correcting images from film projectors. As in the calibration of color, screen-masking adjustments are
global—that is, you can create a variety masks and download them to projector memory for use with sources
as desired. Mask settings are distinct from aspect ratio or screen position settings.
NOTE
: Most screen
functions are also now available in the TPC Screen menu (password required).
Projector Configuration File
Nu
merous settings collected into a single Projector Configuration File further control processing variables for
optimized display of specific source material. Each PCF file, typically created in DCP Librarian , pre-defines
color space, target color gamut, source aspect ratio (resolution), and gamma (a.k.a. degamma) settings for a
cinema or non-cinema source. Once the collected settings are downloaded to the projector’s internal memory,
their PCF can be assigned to the corresponding
CP2000-XB input connection and quickly applied via a
controller such as Christie’s Touch Panel Controller . No further adjustment in processing should be required.
