Noise Reduction Filter Functions

Related Setting Items:
The camera has noise reduction functions. The noise reduction methods vary depending on the
channel.
Three filters are available:
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. (SW-4000TL-10GE
l
only)
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.

Non-Volatile Flash Memory

Storing Data in On-Camera Flash Memory
The camera has non-volatile memory for users to store data. Refer to the technical note "Storing
Data in On-Camera Flash Memory" for more information.
Note: JAI strongly recommends saving images to the PC or other storage location because
the non-volatile flash memory may not have enough memory size to store large data.
