2.3.6 Luminance continuous code motion compensation level setting
SUB_ADDRESS = 50h(W): Luminance Continuous Code Motion Compensation Level Setting
Table R2-3-6 (4) Auto Mode Motion Compensation Level Setting (Valid at NRAUTO = 1)
Register name
YMS[3:0] Initial value: 0100;
AYMS[1:0] Initial value: 00; Setting range: Refer to table R2-3-5 (4).
DATA_BIT
Sets luminance signal continuous code motion compensation level.
Settable in 0 to 30 levels for the luminance signal field differential absolute value data.
Assigns respective setting values to the 3-continuous codes, 4-continuous codes and 5-continuous codes
motion detection, decides data having large motion components for | LY| exceeding the setting, and
performs the noise attenuation compensation (YNRM = 0) or NROFF compensation (YNRM = 1).
Sets auto mode luminance motion compensation level.
Valid in the auto mode noise follow-up state.
