Coring
To reduce the contour enhancement for fine low contrast details like grain.
The standard value 0% applies the selected amount of contour correction to all
details. For grain reduction an adjustment value around 10% is sufficient.
At 100% coring value, only very high contrast details are enhanced.

Gang
This function offers contour enhancement in dependence on detail size (spatial
frequency).
In order to enhance small picture details, select a higher value (high values
correspond to high frequencies), to enhance contours of coarse details, select
a low value.
To change the settings, slide on the touchscreen or use the digipot controls.
The controls for vertical and horizontal peaking can be handled separately
but if there is no need for split settings use the Gang function.
If the button ”Gang” is switched on, the horizontal and vertical peak frequency
can be adjusted together with either one digipot or slider.
E.g. the vertical peak frequency level is changed and the horizontal level fol-
lows in the same way.
The ratio between both levels are maintained in this operation mode.
The ranges of the horizontal or vertical peak frequency are:
Selection: 0 / 1 / 2 / 3 / 4 / 5 / 6 / 7
”0” range of the horizontal or vertical peak frequency set to 0
