Crystal Vision
Introduction
The Transient Tolerance control is provided to allow these overshoots to pass through the
CoCo 3G without resulting in downstream RGB errors.
There are three levels of tolerance to transient overshoot selection:
Maximum - Large transients that are less than eight pixels in length will be allowed to pass.
Minimum - Small transients that are less than eight pixels in length will be allowed to pass.
Off - No tolerance to transients. All transients are not allowed to exceed gamut levels.
Black cleanup
A useful feature of the CoCo 3G is its black cleanup control. The black cleanup works by
returning any video Luma content that falls below a previously set threshold level to black.
Sub black information is passed unaffected.
The range of adjustment for the black cleanup threshold control is 0-10% of peak white.
Black cleanup example threshold set to 5%
