In this mode, R,G,B or NIR can be set individually.
Settings:
Range: 0 to 8191 LSB (200%)
Setting point: 512
7.19. Command NR - Noise Reduction
Noise levels less than 16 LSB (4LSB) which are superimposed on the video signal will be
eliminated. The deterioration of spatial frequency is minimized. The improvement of
signal-to-noise ratio will be 3dB as the maximum although it depends on the object.
Figure in ( ) is for 8-bit output.
Settings:
0=ON, 1=OFF
7.20 Command PBC – Enable Pixel Black (FPN) Correction
This command enables (or disables) the “pixel black level” correction function, which
compensates for Dark Signal Non Uniformity / Fixed Pattern Noise (DSNU / FPN) for
individual pixels.
Settings:
0 = Off
1 = Factory setting
2 = user area
Associated functions:
Command PBR
Applicable modes:
All
7.21. Command PBR – Run Pixel Black Correction and Store to User Area
This command initiates the “pixel black level” correction function, and stores the settings
in the user area. When this function is activated, lens must be capped.
Settings:
0 = Run this function
Associated functions:
Command PBC must be set to 2
Note:
•
This function requires that no light reaches the image sensors. The lens must therefore
be covered by a lens cap, or put the F-mount protective cover on the camera, when
executing this function.
•
As the black level is influenced by the exposure time (especially for long exposure times
at slow scan rates) it is recommended to perform the pixel black correction at the
Setting point
