Name and function
Table 15-2. Write Register Functions (5/14)
0: x 6/8 (small noise reduction effect and small after-image)
1: x 7/8 (large noise reduction effect and large after-image)
The magnitude of the NR effect is specified.
0: 6 LSB (small noise reduction effect and small after-image)
1: 8 LSB (large noise reduction effect and large after-image)
An input larger than specified is assumed to be a motion
component, resulting in 0 being output.
00: 0 LSB (YNR off) to
11: 3 LSB (large noise reduction effect and large after-image)
An input larger than specified is assumed to be a motion
component, resulting in a limit value being output.
