Description
Gain Factor for UV correction
UV corrections only in positive direction
Minimum denominator for UV processing
Round or Truncate in interpolation for Y transfer function
8-bit signed offset for black stretch value
This is the 33rd histogram variable and this is the only way to add an
offset from a Yout=Yin curve for Yin= -256+ped register. But it
affects all other 32 values too.
Compensate Y in order to prevent illegal colors in RGB space
Strength of blue stretch effect (0..15) higher value = greater effect
Blue stretch detection area (0..7) lower value = greater detection
area
Strength of skin tone correction effect (0..4) higher value greater
effect
Direction of correction (0..4), lower value = towards “yellow” higher
value = towards “red”
Skin tone detection area size (0..2) higher value = greater detection
area
Maximum correction(0..15), higher value = stronger correction
allowed
Green detection area maximum saturation (0..7) higher value =
effect extends to higher saturations
00 = factor of 0
01 = factor of 0.5
10 = factor of 1
11 = factor of 2
0 = denominator larger than or equal to 64
1 = denominator larger than or equal to 128
1 = Round
0 = Truncate
1 = Y compensation on
0 = Y compensation off
Blue stretch functionality
1 = Enable
0 = Bypass
Skin tone correction functionality
1 = Enable
0 = Bypass
