NOISE REDUCTION TAB
The Noise Reduction tab is used to configure parameters associated with the video noise reduction
processing. The General Noise Reduction section is a motion adaptive spatial-temporal and recursive
noise filter.
7.5.1. Temporal Noise Reduction Levels
The Temporal Noise Reducer (TNR) Level controls the strength of the applied Temporal Noise Reduction
filter. Select the level of noise reduction to be applied by selecting the appropriate value from the drop
down menu as shown below.
Off
General noise temporal will not be enabled.
Low
A Low level of temporal noise reduction will be applied.
A Medium level of temporal noise reduction will be applied.
Medium
High
A High level of temporal noise reduction will be applied.
Note: Setting the value higher than needed to remove the noise present, will over
soften areas of low amplitude, fine details.
Note: Setting the value too low may cause the circuitry to leave random noise that it
could remove. However, removal of low-level details will be minimized
