(1) Auto Mode Luminance Noise Reduction Mode Settings (AYABN)
Sets whether or not to use the luminance absolute noise reduction mode in the auto mode luminance noise
follow-up status (YDTO2 = 1).

(3) Auto Mode Luminance Noise Convergence Level Settings (AYNS[1:0])
Sets whether or not to use the luminance noise convergence 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 convergence level is ignored.
