•
Luma – set to On to enable the Luma control or Off to disable. The luma channel
can be adjusted independently of the chroma channel for noise reduction and
motion threshold while in any of the Motion Adaptive Recursive modes.
•
Use the Luma NR Factor and Threshold controls to fine tune the noise as
it appears on a waveform monitor and the Show Noise function set in the
Bypass mode below.
•
Chroma – set to On to enable the Luma control or Off to disable. The noise
reduction and threshold of the chroma channel can be adjusted independently of
the luma channel with these controls. A Luma Tie setting is provided that controls
the chroma filter based on the motion estimation on the luma channel. Not only is
noise more effectively reduced when this control is active, but it can also reduce
the appearance of cross-color artifacts from poor upstream decoding of composite
signals.
•
Use the Chroma NR Factor and Threshold controls to fine tune the
chroma noise factor.
•
Bypass – set the DNR output mode in conjunction with the Vid Out menu Bypass
function with this control. You may use this control to view the desired DNR
output for comparing noise reduction or detail enhancement. Refer to the Vid Out
menu for details on setting this mode.
