• Detail Enhancement Controls Sharpness Level, Threshold, and Noise Reduction controls (individually
described below) which can be used to tailor output video sharpness per
program material and aesthetic preferences.
Note: Detail Enhancement Controls apply to both SD and HD
conversions.
• Sharpness Level Control Adjusts the aggressiveness of sharpening applied to MPEG video.
Optimum setting results in overall perception of increased sharpness,
while avoiding pattern noise artifacts.
(Range is 0 thru 255)
• Sharpness Threshold Control Adjusts the point at which sharpening rules become active. Data below
the threshold setting is passed unaffected.
Higher settings allow for a more subtle sharpness enhancement
(especially with content showing motion). Lower settings allow more
content in general to be acted upon by the enhancement process.
(Range is 0 thru 255)
• Noise Reduction Control Adjusts the amount of statistical low-pass filtering applied to the data.
Using this control, regular pattern noise artifacts from the sharpening
process can be reduced, resulting in subjectively smoother raster
backgrounds and detail boundaries.
(Range is 0 thru 63)
