YAVR1[5:0] Initial value: 00_0000; Setting range: 00_0000 to 11_1111
Sets increase direction decision average value level of luminance noise state 1.
Becomes the decision level when the noise level is in the increase direction.
YAVR1[5:4] is an integral part and YAVR1[3:0] is a decimal part.
Make sure to set a value smaller than YAVR2[6:0].
YAH1 Initial setting: 0; Setting range: 0 to 1
Sets decrease direction decision average value level hysteresis coefficient of luminance noise state 1.
The decision level of the noise level in decreasing direction is set by (YAVR1[5:0]) × (Coefficient).
CAVR1[5:0] Initial value: 00_0000; Setting range: 00_0000 to 11_1111
Sets increase direction decision average value level of chrominance noise state 1.
Becomes the decision level of the noise level in increasing direction.
CAVR1[5:4] is an integral part and CAVR1[3:0] is decimal part.
Make sure to set the value smaller than CAVR2[6:0].
CAH1 Initial value: 0; Setting range: 0 to 1
Sets decrease direction decision average value level hysteresis coefficient of chrominance noise state 1.
The decision level of the noise level in the decreasing direction is set by (CAVR1[5:0]) × (Coefficient)
YAVR2[6:0] Initial value: 111_1111; Setting range: 000_0000 to 111_1111
Sets increase direction decision average value level of luminance noise state 2.
Becomes the decision level of the noise level in increasing direction.
YAVR2[6:4] is an integral part and YAVR2[3:0] is a decimal part.
Make sure to set the value larger than YAVR1[5:0].
YAH2 Initial value: 0; Setting range: 0 to 1
Sets decrease direction decision average value level hysteresis coefficient of luminance noise state 2.
The decision level of the noise level in decreasing direction is set by (YAVR2[6:0]) × (Coefficient).
