Luminance noise level of 8 frames average (YNAMS = 0), or of 1 frame (YNAMS = 1), of noise
absolute value average of lines detected at NRDTON = 1
Updated every frame. 7Fh is read out if the noise level exceeds 7Fh.
YAVRO[6:4] is an integral part and YAVRO[3:0] is a decimal part.
Color difference noise level of 8 frames average (CNAMS = 0), or of 1 frame (CNAMS = 1), of noise
absolute value average of lines detected at NRDTON = 1
Updated every frame. 7Fh is read out if the noise level exceeds 7Fh.
CAVRO[6:4] is an integral part and CAVRO[3:0] is a decimal part.
Luminance Noise Detection Flag
At NRDTON = 1, YDTO1 is set to “1” if YAVRO[6:0] > YAVR1[5:0] state continues in 4 frames.
Color difference noise detection flag 1.
At NRDTON = 1, CDTO1 is set to “1” if CAVRO[6:0] > CAVR1[5:0] state continues in 4 frames.
