3.8. Enhancement
The enhancement menu provide image enhancement functions. Note that the enhancement settings
apply to video input signals only, not computer graphics signals.
3.8.1. Sharpness
Available 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.
3.8.2. Detail
Available 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.
3.8.3. Video Filters
The video filters menu provides LTI/CTI filters and TRNR/MNR noise reduction filters.
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.
