Configuration and Adjustments
• Manual mode – when Auto mode is turned off, the temporal recursive
filter is in Manual mode. This will activate a number of controls for
manual temporal filtering.
The Distance control is set to determine the sensitivity to motion
between the current frame and historical frames. This threshold repre-
sents a percentage of the current pixel value that the historical pixel
value must be within in order to be considered unchanged. Therefore,
a setting of zero would detect motion at every pixel, applying no fil-
tering occurring. A setting of 40 would be less sensitive to motion, tem-
porally filtering every pixel which could result in blurring or any
objects or areas that are in motion. If the Distance control is set too low,
too little filtering may occur, whereas, if set too high, too much filtering
will be applied.
The No Motion control sets the historical weighting factor for areas in
the frame where no motion has been detected. A setting of 100% forces
the filter to use only historical data in areas where no motion has been
detected. A setting of zero forces the filter to use only current data in
areas where no motion has been detected.
The Motion control sets the historical weighting factor for areas in the
frame where motion has been detected. A setting of 100% forces the
filter to use only historical data in areas where motion has been
detected. A setting of zero forces the filter to use only current data in
areas where motion has been detected.
