PODT Initial value: 0; Setting range: 0 to 1
Noise detection is set for valid data only.
The function operates regardless of PNON. * For monitor cameras
NRDTF Initial value: 0; Setting range: 0 to 1
Sets noise detection field.
Noise detection is performed once in one frame in the vertical blanking period of one side. Performs
selection of that detection field.

NDCT Initial value: 0; Setting range: 0 to 1
Sets noise detection area in the blanking period.
Selects the setting of the basic noise detection period.

PNON Initial value: 0; Setting range: 0 to 1
Sets noise detection area.
Selects the use of "vertical blanking + valid data area" for noise detection.
* Priority is given to PODT=1.
