Tuning Guidelines: Advanced Settings
30 SMX-12A2x Series Gigabit Ethernet Camera User Guide
● Mono - sensor pixels data is transformed into a monochrome stream
● Bayer - standard Bayer matrix
● Nearest - this is the fastest algorithm that gives the worst, compared to other algo-
rithms, image quality
● Bin 2x2 - four adjacent Bayer matrix pixels become one RGB pixel
● Bilinear - this a slower algorithm that gives a better quality, the optimal option in
terms of quality and noise sensitivity
● Adaptive bilinear - improved bilinear algorithm
● Laplacian - the slowest algorithm that gives the best quality and high noise sensitiv-
ity
● Preview - 1:2 decimation (every second pixel is excluded from the image) that gives
a relatively good video output on slow computes.
Black level
Black level slider allows changing sensor’s level of black. By default, this value is set
automatically. But when additional tuning is needed, you can uncheck the Auto box
and move the slider up or down to improve the image. However, in most of the cases, it
is recommended to change brightness instead (see
“Color Correction Settings” on page 27 ).
Median filter
Median filter turns on pixel averaging. The brightness of every single pixel becomes
affected by the brightness of its neighbor pixels and the whole image becomes
smoother.
There are two types of the hardware median filter:
● Median Filter Type 0 - reduces speckle noise and salt and pepper noise.
● Median Filter Type 1 - preserves edges and is useful when edge blurring is unde-
sirable.
Hardware gamma correction
Check the Enable gamma correction box if you want the camera to perform gamma
correction on the hardware level.
