Sets noise reduction auto mode transition.
Selects noise reduction transition mode at NRAUTO = 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.
Sets noise detection area in the blanking period.
Selects the setting of the basic noise detection period.
Sets noise detection area.
Selects whether the valid data area is used or not for noise detection.
