ADMIN / GAMUT MENU OPTIONS
Measured
(MCGD)
Activate each color, which projects a special full-field test pattern, and enter the x/y
coordinates measured at the screen. See Measured (MCGD) Notes below.
Pattern Off Leave the full-field test pattern mode.
Target (TCGD) Activate each color and enter the x/y coordinates desired.
Gain Luminance (intensity) of each color when compared to white.
White Tolerance Define the location (enter x/y coordinates) of each corner of a “tolerance box”
around the target white point for the current TCGD. A tolerance minimizes the light
discarded in achieving the target white in the display, and is recommended for
theatre use. Without tolerance, the target white point will be matched precisely in
displays using this TCGD, regardless of how much light must be discarded.
Checkbox Enter a checkmark to enable tolerance around the white point. Delete the
checkmark to match the white point precisely.
Restore Cancel new (unsaved) TCGD settings.
Cancel tested (via “Test” button) but unsaved MCGD settings.
Test Apply current settings to the image without saving.
Create MCGD Save current MCGD settings as a new “OnSite” or other file name. NOTE: “OnSite”
is a permanent over-write of any previous “OnSite” file, and cannot be cancelled
in the future except by another over-write. If desired, create other MCGD files to
reference under specific conditions and for specific sources or channels. See
Create MCGD Notes , below.
Create TCGD Save current settings to a new TCGD. NOTE: Industry-standard TCGD files are
write-protected and cannot be modified unless saved under a different filename.
For theatre use, there should be little need to create custom TCGDs, as the pre-
defined TCGDs are used instead.
MEASURED (MCGD) NOTES:
For each color, record the native “uncorrected” x/y color
coordinates measured at the screen. These values simply represent the currently
viewable primary colors, and collectively (when saved) will define the raw color
performance “reference point” for this projector in the current environment. Each
radio button activates the corresponding full-field YCbCr test pattern of this native
color so that measurements can be taken. For example, to measure the red
coordinates, click the “Red” radio button to change the screen display to full-field
red, and measure coordinates at the screen. Repeat for each color, and record them in
the nearby x/y text boxes. After all colors have been measured and recorded, select
Pattern Off to leave the special test pattern mode. To cancel changes and return to the
previous MCGD coordinates, leave the menu without saving.
CREATE MCGD NOTES:
This button collects the current color values entered for
“Measured (MCGD)”, where you can save them as a new “OnSite” MCGD file or as
a different MCGD file with a different name. Note that a new “OnSite” overwrites
any previously defined “OnSite” file, and will be the default reference point for all
future color processing—the old “OnSite” file cannot be recovered. By default, the
projector will refer to “OnSite” data to calculate the corrections needed to achieve a
known
target color performance standard in the future. However, if the site requires
more than one set of native MCGD values (such as when an auxiliary lens is swapped
in or out), you can create a new MCGD file with a different file name. Each setup
(channel) can then use any desired MCGD file as the basis for the color corrections
needed for a target color. MCGD files are chosen in the
Custom menu.
NOTE: Once created, user-created MCGD files can be deleted only by using
Christie’s licensed DCP Librarian software .
