CBDTO
(4) Auto Mode Color Difference Noise Convergence Level Settings (ACNS[1:0])
Sets whether or not to use the color difference noise convergence level automatic setting in the auto mode noise
follow-up status (CDTO2 = 1).
When AMM = 0, noise reduction stops with CDTO1 = 0, so the color difference noise convergence level is
ignored.
(5) Auto Mode Luminance Noise Upper Limit Level Settings (AYLM[1:0])
Sets whether or not to use the luminance noise upper limit level automatic setting in the auto mode luminance
noise follow-up status (YDTO2 = 1).
When AMM = 0, noise reduction stops with YDTO1 = 0, so the luminance noise upper limit level is ignored.
(6) Auto Mode Color Difference Noise Upper Limit Level Settings (ACLM[1:0])
Sets whether or not to use the color difference noise upper limit level automatic setting in the auto mode color
difference noise follow-up status (CDTO2 = 1).
When AMM = 0, noise reduction stops with CDTO1 = 0, so the color difference noise upper limit level is
ignored.
