Saturation Factor Cb [SATCB : 5ch : 80h]

Saturation Factor Cb

Saturation Adjustment is performed for multiplying Cr,Cb data by Saturation Factor Cr,Cb,

respectively. Programmable range of Saturation Factor Cb,Cr is 0 ~ 2.

For instant, Sat Cb = Cb data * B<7:0>/128.

Edge Enhancement Threshold Low [EDTHLO : 5dh : 05h]

Edge Enhancement Threshold Low

Edge Enhancement Threshold High [EDTHHI : 5eh : 80h]

Edge Enhancement Threshold High

Chroma Suppression Function [CHSUPFNC : 5fh : 64h]

Saturation Level

Suppression Gain Minimum

0% of difference between Current Cb,Cr data and reference Cb,Cr level. So,

Chroma Suppressed Cb,Cr data are equal to Current Cb,Cr data.

25% of difference between Current Cb,Cr data and reference Cb,Cr level.

50% of difference between Current Cb,Cr data and reference Cb,Cr level.

Saturation Level

75% of difference between Current Cb,Cr data and reference Cb,Cr level.

Suppression Gain

Minimum

When Amp Gain is greater than Suppression Gain Minimum, Chroma

Suppression Function is started.
