6.11.1.2. Detail Gain
This control selects the level of the detail gain with a range of 0 to 127, where 0 refers to no increase in
detail gain. A typical range for this control is 0 to 50. Higher values will normally distort the image beyond
the range that is normally considered acceptable. The default value is 24.
6.11.1.3. Enhancement Limit
This control selects the largest detail value to be added back into the signal. The range is from 0 to 63.
The detail that has a value larger than this value will be clipped. The default value is 16.
6.11.1.4. Horizontal Band
This control selects the horizontal frequency band to be enhanced. The horizontal band is adjusted in
increments of 5, where 0 selects the lowest frequency band available and 20 the highest.
6.11.1.5. Vertical Intensity
This control selects the intensity of the vertical enhancement process, as a ratio of the horizontal
enhancement. The range is 0 to 100% in increments of 25% where 0% refers to no vertical enhancement
and 100% provides a vertical intensity that is equivalent to the horizontal.
6.11.1.6. Luma Floor
This control selects the minimum Luma value that will be enhanced with a range of 0 to 15. The default
value is 1. Pixels with a value below this floor will be left untouched.
6.11.1.7. Detail Noise Floor
When the image detail has a value that is below this floor it will be deemed to consist mostly of noise. As
such, the pixel associated with that detail level would be left untouched. The Detail Noise Floor has a
valid range of 0 to 15 with a default value of 2.
