8.0 ADJUSTING THE IMAGE

correct blacks and whites without crushing. See figure Adjusting Input Levels Using the Peak Detector below.
1) Display a 16 level grayscale test pattern from the desired external source, and enter a checkmark in the Input
Peak Detector check box. NOTE: The Input Peak Detector will initially render the grayscale as a uniform gray field
before adjustment or extreme crushing.
2) Display one primary color. NOTE: Select Auto Color Enable to ensure the correct color is displayed for each
setting.
3) For the current color, adjust its corresponding Black level slide bar just until a single band of black appears at
one edge of the screen. This band represents the first band of the grayscale pattern, which should be 100% black.
4) With the same color still active, adjust its corresponding Input Drive slide bar just until a single band of color
appears at the opposite edge of the screen. This band represents the last band of the grayscale pattern, which
should be 100% white (or the current color, if a certain color is enabled).
5) Check the black band and adjust the black level slide bar if necessary. NOTE: Adjusting the black levels affects
the gain. Only adjust when necessary.
6) Repeat Steps 3-5 with the two remaining primary colors. When each primary color shows one optimized black
band and white (or colored) band, the input levels for this source are correctly set. Upon exiting the Input Levels
menu, the Peak Detector check box will clear.
Adjust Input Levels using the Peak Detector (Red example)
• Color Enable
Select which color or colors you want to see in the display, useful while working with color temperature white levels
or input levels.
NOTES:
1) Input levels apply for the current source only, but for any color temperature used.
2) If color temperature is set up based on the internal test patterns, you can set up input levels for a given source so
that it matches the color temperature of the internal test patterns.
Advanced Image Settings - Submenu
Use the Advanced Image Settings submenu to make the adjustments necessary for lesser-used but more
specialized applications on your projector.
• Gamma Settings
The system offers two types of gamma correction. Gamma correction can be applied to a specific source to correct
for luma encoding. This is a channel setting and reapplied every time the same signal is detected. This is the
'Gamma' control. On the other hand the system also provides a global Gamma Correction control. The global
control offers an offset applied to all channels. This offset is used to compensate for changes in ambient conditions
such as ambient light in the room and projected material.
• Gamma Correction
Applies a global offset to all gamma settings for each channel. It affects the shape of the curve by performing a
linear transform toward a gamma curve of 1.0 while the control is increasing and likewise a linear transform oward a
gamma of 3.0 as the control is decreasing. The control should only be adjusted to compensate for ambient
conditions. To correct a particular source only, use the Gamma control.
• Gamma
Select the base gamma table for a given source. Select from one of the standard tables, a custom gamma function,
or select an arbitrary gamma table that has been downloaded to the projector.
