Calibration - Runco D-73d Ultra Installation & Operation Manual

Use the Calibration menu to perform advanced picture quality adjustments. This menu
should be used by ISF-certified technicians only.
You must enter a passcode to access the Calibration menu.
Note
To recall the ISF Night or ISF Day settings, select "ISF Night" or "ISF Day" from the
Memory Presets menu (see page 78) or use the corresponding remote control buttons.
Display Color - Common Settings: Use the Display Color - Common Settings menu
to adjust the color balance at the Dimension Digital Controller output. These settings
are saved independently for each input and display mode.
• Gain: Use the Gain controls to correct color imbalances in the bright areas of the
image. A good way to do this is to use a test pattern consisting mostly of solid white
areas, such as an 80 IRE "window" pattern. If the white areas contain traces of red
(Pr), green (Y) or blue (Pr), decrease the Gain for that color.
• Offset: Use the Offset controls to correct color imbalances in the dark areas of the
image. A good way to do this is to use a test pattern consisting mostly of dark gray
areas, such as a 30 IRE "window" pattern. If the gray areas contain traces of red
(Pr), green (Y) or blue (Pr), decrease the Offset for that color.
• Gamma: Select Gamma from the Display Color - Common Settings menu to choose
a de-gamma curve. Used correctly, the Gamma control can improve contrast while
maintaining good details for blacks and whites. If excess ambient light washes out
the image and it becomes difficult or impossible to see details in dark areas, lower
the gamma setting to compensate. This improves contrast while maintaining good
details for blacks. Conversely, if the image is washed out and unnatural, with
excessive detail in black areas, increase the setting.
• Mode: With the D-73d, two Gamma adjustment modes are available: Simple or
Advanced. The two modes are mutually exclusive; when you select the Simple
mode, the Advanced selection in the Gamma menu is grayed out. Likewise, when
you select Advanced, the Simple selection is grayed out.
• Simple: Use the Simple Gamma control to perform gamma correction at the
display according to a simple power law gamma function. The value chosen here
corresponds to the power variable in this equation:
Power
Output = Input
The Dimension Digital Controller applies this gamma curve to all three primary
color channels (red, green and blue).
• Advanced: To select a custom gamma curve, select Mode from the Gamma
menu and set it to Advanced. Then, select Advanced from the Gamma menu to
select one of up to 20 pre-programmed gamma tables. Custom gamma tables
provide the ability to perform complex, non-linear gamma correction on each
primary color channel independently of the others.
