ISFTo access the ISF Calibration menu, select ISF from the Main Menu and press ENTER. Use the
number buttons on the remote control to enter the ISF Calibration menu passcode when
prompted and press ENTER again. Then, press MENU on the remote control.
Picture Memory/Copy Settings: These settings are described in the Picture Adjust section
(page 46).
Brightness/Contrast/Color/Tint/Sharpness/Color Temperature: These settings are
described in the
Picture Adjust section (refer to page 46).
White Balance: To remove any trace of color from the white areas of the projected image,
select the “Custom
1” or “Custom 2” Color Temperature. Then, choose White Balance from
the ISF menu and press ENTER.
•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, green or blue,
decrease the Gain for that color.
• Offset: Use the Offset controls in the White Balance sub-menu 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, green or blue, decrease the Offset for that color.
The Gain controls increase or decrease the full-scale input range; the Offset controls shift
the entire range, resulting in a change in brightness.
Figure 4-8 shows how the Gain and
Offset controls interact with each other.
