The sliders for all regions which are not involved in edge blending for a given multiple unit configuration
are greyed out, and the black level uplift for all these regions can be set together using the Non-Blend
Region parameter.
3.9.7. Reduce Black-Level Uplift Width
The Black Level Uplift field may need to be adjusted to achieve a perfect result. There may be an area
of light leakage beyond the edge of the active image from the projector. With these controls the edges
of the black uplift region can be moved so they can be aligned with the edges of the area of light
leakage. In the case of projection under non-rectangular conditions the projection fields of adjacent
projectors are not aligned with the blend region. The corners of the non-blend region can be moved to
allow tracking of the edge of the projection field of adjacent projectors.
3.10. Enhancement
The enhancement menu provides image enhancement functions. Note that the enhancement settings
apply to video input signals only, not computer graphics signals.
3.10.1. Sharpness
Settings: -50 to 50 in steps of 1
Control of the sharpening enhancement filters' levels. These are peaking filters to improve high-
frequency response.
Note that setting this control too high on a signal which already has good high frequency response will
cause ringing or ghosting.
3.10.2. Detail
Settings: 0, 1, 2, 3
This filter provides powerful 2D image enhancement which can be used to greatly improve detail
definition and clarity without causing image ringing or ghosting.
It improves both horizontal and vertical detail.
Correct setting of the detail enhance filter can make SD signals look virtually indistinguishable from true
HD.
At setting 0 the filter is switched off, with setting 3 providing the highest effect.
3.10.3. Video Filters
The video filters menu provides LTI/CTI filters, TRNR/MNR noise reduction filters and a CCS cross
color suppression filter.
The LTI filter enhances the sharpness of the luminance component.
The CTI filter enhances the color sharpness of the chrominance signal by increasing the steepness of
color edges.
TRNR (Temporal Recursive Noise Reduction) and MNR (Mosquito Noise Reduction) are available for
SD input signals only. These filters reduce spatial and temporal noise as well as block artifacts.
CCS is a filter to reduce luminance to chrominance cross talk of composite video signals (only) which
appears as a coarse rainbow pattern or random colors in regions of fine details.
3.10.4. Flicker Filter
By default the filters are off.
