Section 2: Installation & Setup

2.9.1 Calibrating the System Using DCP Librarian Setup Software

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 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-SB 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

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 auxiliary 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).

PCFs (Rare)

Numerous 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 input connection and quickly applied via a controller

such as Christie’s Touch Panel Controller. No further adjustment in processing should be required.

Refer to the DCP Librarian User’s Manual

for all DCP Librarian Setup Software operating details and

procedures.
