IFMD Mode
This control enables the user to set the motion-processing mode for the de-interlacer. The user may
select from
Disable, Auto
or
Noise Adaptive
using the following drop down menu.
Disable
No motion adaptive processing will take place and all pixels will be treated as static.
Auto
Per pixel motion processing will take place and de-interlacing filters will automatically
change based on the amount of per pixel motion detected.
Noise Adaptive
Per pixel motion processing will take place and de-interlacing filters will automatically
change based on the amount of per pixel motion detected and the automatically
measured amount of noise in the image. This is the recommended setting for the
highest image quality.
6.8.1.4.
IFMD Threshold
With this control, the user can change the threshold of what is deemed motion for the deinterlacer. The
user can set the
IFMD Threshold
by moving the threshold slider to the left or the right.
The IFMD threshold value ranges from 0 to 15. The threshold can be adjusted in increments of 1. The
IFMD Threshold
is set to 8 by default. A value of 8 gives the best overall image quality for a wide variety
of image content.
6.8.1.5.
Film Detection Mode
The 7812UDXD series modules have the ability to automatically detect embedded 3:2 and 2:2 sequences.
When such sequences are present inverse 3:2 and 2:2 is performed so that mathematically lossless
conversion back to progressive may be achieved. For optimal performance, the
Auto
mode of operation is
highly recommended. The
Film Detection Mode
drop down menu enables the user to set the operating
mode as shown below:
Auto
The card will automatically detect video sequences including embedded 3:2 and
embedded 2:2 sequences. Processing will be automatically adapted to match the
detected content. If no film mode sequence is detected, the de-interlacer will
automatically revert to video mode processing. This is the recommended setting
for this control.
Video Only
The video de-interlacer will operate in
video only
mode and will utilize its internal
motion adaptive and edge interpolation process for de-interlacing the input signal.
