7. Repeat Steps 4 and 5, but adjusting gain.
8. Repeat Steps 3-7 for all remaining colors. Your RGB source should now be OK.
Two sets of values are automatically saved with these controls—one value for Input
#1, and one for Input #2 (analog). The current set of values depends on which source
is in use. This enables a source to be processed correctly via two different inputs.
Odd Pixel Adjustment
1. Red Odd Pixel Offset
2. Red Odd Pixel Gain
3. Green Odd Pixel Offset
4. Green Odd Pixel Gain

Figure 3.25. Using "Odd Pixel Adjustment"
NOTES: 1) Adjust offset before gain, since offset affects gain. 2) A value of 128
represents no change in normal odd pixel offset or gain. 3) Odd Pixel Adjustment
eliminates "one pixel on, one pixel off" artifact only, not any type of larger artifacts.
Reserved - No function.
Peak Detector
The "Peak Detector" is a fast method for defining individual input levels, and can
improve the accuracy of input levels set by the Auto Input Level function. Enabling
the "Peak Detector" activates a special operating mode for detecting only pixels that
are considered black or white—all other levels are displayed as a mid-level gray.
When used with a 16-step grayscale pattern in which the two black and white bands
are known to be at opposite edges of the image, you can watch these isolated areas
while adjusting individual blacklevels and input drives until both bands are just
visible. Images from this source will then display correct blacks and whites without
crushing or washing out.
NOTE: If using Peak Detector with PIP, both images must have the same color
space.
Level Detector
The "Level Detector" checkbox enables specific thresholds for blacks and whites—
input levels that fall below a specified Level Value (see below) are displayed as
black, and all others are displayed as white. It aids in Odd Pixel Adjustment. To use:
1. Enable "Level Detector" and display a continuous grayscale.
2. Set "Level Value" to near black (such as 200).
3. Adjust Offsets to minimize area of black stripe.
4. Set "Level Value" to near white (such as 800).
5. Adjust Gains to minimize area of white stripe.
