FOLD MIRROR ADJUSTMENT:

indicate that the fold mirror has become misaligned with the rest of the optical
system, resulting in cropping of data. Correct as described below:
1. Remove the fold mirror access plate from the underside of the projection
head—this plate is located just below the lens. Two access holes will be
revealed, through which you can adjust two fold mirror screws:
•
To raise or lower the
image, adjust the
screw closest to the
operator's side.
•
To move the image
left or right, adjust the
screw furthest from
the operator's side.
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 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.
