Peak Detector
The “Peak Detector” is fast method of 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.
Level Detector
The “Level Detector” checkbox enables a 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.
Level Value
The “
Level Value
” defines the value to be used by the
Level Detector
in recognizing blacks
and whites. See Level Detector, above.
