Preliminary Calibration; Color Adjustment Procedure - Christie CineIPM-2K User Manual

OPERATION
The default login provides access to security settings, where you can define other
users with the same or fewer rights. Use "unlimited" rights for most applications. For
all logins, the Service menu is still protected with its own password.
NOTES: 1) Any proxy server settings that interfere with this type of link should be
disabled for using ChristieNET. Disable through Internet Explorer's < Tools>
<Internet Options> <Connections> <LAN Settings>. 2) Your PC must be Java-
enabled to v1.4.2 or higher to run ChristieNET. 3) Certain controls provided through
ChristieNET are non-functional for use with the Cine-IPM 2K.

display. References to "projector" in this section assume a Cine-IPM 2K is
connected.
NOTES: 1) Connection of multiple units is described in 2.6, Linking Multiple Cine-
IPM 2Ks. For communications, see also 3.6, Adjusting System Parameters and
Advanced Controls. 2) Assumes that each Cine-IPM 2K is connected to a CP2000.
Matching Colors
In a multiple-image wall, you will likely want to precisely match the hue and intensity of

colors from image-to-image so that your full wall is as uniform as possible. This
matching is typically done in conjunction with brightness uniformity and edge
blending.

Preliminary Calibration

As a final part of the manufacturing process, all primary colors in the Cine-IPM 2K
are precisely set to pre-established values to help ensure that overall color
performance from your display device is optimized and is as accurate as possible
(refer back to Figure 3.20). Upon installation at a site, however, lighting and other
environmental factors may slightly change how these colors appear on each screen.
While the change is negligible in most cases, you may prefer to recover the originally
intended color performance before trying to match colors from several CP2000s.
The recommended first step in achieving such consistency is to use a color meter to
measure the native primary colors—red, green, blue, and white—as they appear at
the screen and record these as Color Primary Settings in the Service menu (password-
protected) for each Cine-IPM 2K. On the basis of these new values, which are stored
in memory, each unit will then automatically calculate any necessary corrections to
reproduce the original factory-set colors under the current environmental conditions.
This essentially calibrates the Cine-IPM 2K to its surroundings, compensating for
factors such as screen type, lamp and/or ambient lighting that can alter the final color
characteristics on-screen, and will improve color accuracy and consistency in a group
of projectors. It ensures a good starting point for further customizing and matching.
To return to the factory-set color primaries, such as when the equipment is moved to
different site, you must access the Service menu (password-protected). Select the
Reset to Factory Defaults? option in the Color Primaries submenu. Then repeat the
calibration process describe above, if desired, and continue with matching of colors.

Color Adjustment Procedure

NOTE: May interact with and affect other color adjustments available in the CP2000.
