Adjusting the sharpness of displayed image.
Scaling Filter Sharpness Control – Peaking Y / Peaking UV
This adjusts the sharpness of luminance(Y) and color(UV). The bigger
the number is in the range of 1~127, the clearer the picture is. The
bigger the number is in the range of 128~255, the more natural video is.
Too high sharpness may cause the vivid noise.
Noise Coring Control – Peaking Coring
Display only the sharp large-edge without assuming the small-edge of
the video as a noise and amplifying it.
Assign the threshold value to
improve the sharpness.
NonLinear Sharpness Control – Peaking Resion1/2 Threshold, Gain
Divide the frequency area and apply the different Gain for each area
rather than evenly apply the sharpness level over the whole image.
