Noise Reduction Filter Functions

Related Setting Items: CorrectionControl,
The camera has noise reduction functions. The noise reduction methods vary depending on the
channel.
RGB
Three filters are available for the RGB channels:
MEDIAN Filter: Apply 1x3 MEDIAN filter
l
Select the target to apply the filter from Red, Green, Blue, and set the Median Filter Mode.
When set to On, this function is enabled. (Default = Off)
FIR Filter: Apply the FIR (Finite Impulse Response) filter
l
Select the target to apply the filter from Red, Green, Blue, and set the FIR Filter Mode.
When set to On, this function is enabled (Default = Off). In FIR Filter, the coefficients of the
three signals (left, center, right) can be set in the range of -2 to 2. The correction value
through the FIR Filter is:
Left pixel read value x Left pixel coefficient +
l
Center pixel read value x Center pixel coefficient +
l
Right pixel read value x Right pixel coefficient.
l
Noise Reduction: Apply the noise filter using JAI's own algorithm.
l
Set the noise reduction intensity in 4 levels. Level1 = weak, Level4 = strong.
Any of the above filters can improve SNR, but it affects the sense of resolution and sensitivity. An
imaging test should be performed before deciding to use this feature.
SWIR
Enables/Disables NoiseReduction in SWIRCorrectionControl.
