YNRM Initial value: 0; Setting range: Refer to Table R2-3-3 (1).
Sets luminance noise reduction motion compensation mode selection.
YFAM Initial value: 0; Setting range: Refer to Table R2-3-3 (3).
Sets luminance adaptive noise reduction mode.
YABN Initial value: 0; Setting range: Refer to Table R2-3-3 (5).
Sets luminance absolute noise mode.
It is possible not to perform 1/2 motion compensation as absolute noise with respect to the motion level
detection noise of luminance signal.
AYABN Initial value: 0; Setting range: Refer to Table R2-3-3 (7).
Sets auto mode luminance absolute noise mode.
By setting to “1”, the luminance absolute noise mode operates in luminance noise follow-up state
(YDTO2 = 1) of the auto mode. (The same operation as YABN = 1.)
YSLT[3:0] Initial value: 0001; Setting range: Refer to Table R2-3-3 (9).
Sets luminance noise reduction noise detection lines/convergence lines inclination.
CNRM Initial value: 0; Setting range: Refer to Table R2-3-3 (2).
Sets chrominance noise reduction motion compensation mode selection.
CFAM Initial value: 0; Setting range: Refer to Table R2-3-3 (4).
Sets chrominance adaptive noise reduction mode.
CABN Initial value: 0; Setting range: Refer to Table R2-3-3 (6).
Sets chrominance absolute noise mode.
It is possible not to perform 1/2 motion compensation as absolute noise with respect to the motion level
detection noise of chrominance signal.
ACABN Initial value: 0; Setting range: Refer to Table R2-3-3 (8).
Sets auto mode chrominance absolute noise mode.
By setting to “1”, the chrominance absolute noise mode operates in the chrominance noise follow-up
state (CDTO2 = 1) of the auto mode. (The same operation as CABN = 1.)
CSLT[3:0] Initial value: 0001; Setting range: Refer to Table R2-3-3 (10).
Sets chrominance noise reduction noise detection line/convergence line inclination.
