Noise reduction digital filter function
This function reduces noise by applying a 1x3 median filter or FIR(Finite Impulse Response)
filter.
SNR can be improved, but it affects the sense of resolution and sensitivity. An imaging test
should be performed before deciding to use this feature.
Select the target to apply the filter from [Median Filter Selector] or [FIR Filter Selector] of [JAI
Custom Control Pixel Correction] from Red, Green, Blue, NIR and set the [Median Filter Mode]
or [FIR Filter Mode]. When set to On, this function is enabled.(Both functions are disabled
(Off) by default.)
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 +
Center pixel read value x Center pixel coefficient +
Right pixel read value x Right pixel coefficient.
