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].
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).
Sets increase direction decision average value level of color difference 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].
Sets decrease direction decision average value level hysteresis coefficient of color difference noise state
1.
The decision level of the noise level in the decreasing direction is set by (CAVR1[5:0]) (Coefficient)
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].
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).
