• Sharpness Mode: Sharpness Mode allows or prevents access to the detailed
sharpness controls in this menu.
In most cases, Simple mode provides a sufficient level of control to produce the best
picture from the most popular sources. In Simple mode, only the
Sharpness (top-most)
slider is adjustable; the others are grayed out.
Choose Advanced mode if you need more precise control over sharpness. In
Advanced mode, only the top slider is grayed out.
• Horizontal Sharpness / Vertical Sharpness / Diagonal Sharpness: Use these
controls to enhance image detail along horizontal, vertical and diagonal edges
respectively.
• Sharpness Overshoot: Use the Sharpness Overshoot control to minimize or eliminate
rings or shadows on dominant edges that cannot be removed using the “simple”
Sharpness control.
• Horizontal Texture / Vertical Texture / Diagonal Texture / Texture Overshoot:
Use these controls to remove artifacts from textured areas that cannot be removed
using the “simple”
Sharpness control.
• Noise Threshold: The Noise Threshold setting adjusts the frequency below which the
Sharpness controls have an effect. Frequencies above the threshold are considered
“noise.”
Generally, the higher the setting, the more noticeable the effect of any adjustments will
be.
Noise Reduction: To apply noise reduction to the source signal, select Noise Reduction
from the Main menu and press ENTER. Noise Reduction is useful for clearing up noisy
images from interlaced SD sources.
• Noise Reduction (Simple Mode): Use the or button to adjust as desired,
keeping in mind that reducing noise (which reduces high frequencies) may also soften
the image.
• Noise Reduction Mode: Noise Reduction Mode allows or prevents access to the
detailed noise reduction controls in this menu.
In most cases, Simple mode provides a sufficient level of control to produce the best
picture from the most popular sources. In Simple mode, only the
Noise Reduction
(top-most) slider is adjustable; the others are grayed out.
Choose Advanced mode if you need more precise control over noise reduction. In
Advanced mode, only the top slider is grayed out.
• General Noise Reduction: General Noise Reduction is temporal and spatial noise
reduction for all types of inputs. The scene is analyzed for differences from frame to
frame and reduces those differences that are not determined to be motion.
• Block Artifact Reduction: Use this control to reduce or eliminate so-called “block
artifacts” in MPEG-compressed video signals (digital broadcasts or DVDs). Set it as
needed to minimize distortion within horizontal and vertical block boundaries.
• Mosquito Noise Reduction: Use this control to reduce or eliminate so-called
“mosquito noise” in MPEG-compressed video signals. Set it as needed to minimize
distortion around the edges of moving objects, moving artifacts around edges and/or
blotchy noise patterns superimposed over the objects.
