UIDELINES
Before you start working with a SMX-160 Series camera, some initial tuning should be
done to remove distortions and noise from the video view.
It is convenient to have camera histogram opened while tuning the image because you
can observe how your changes are reflected in the histogram.
Quality of the image directly depends on such parameters:
● Black level (Amplifier DAC raw offset)
● Column balancing (Amplifier DAC fine offset)
● White Balance for the SMX-160C (color) model
These parameters should be always tuned at the beginning of the camera work. Besides,
each time when the Black level and Column balancing are changed, the White Balance
should be tuned as well.
Concerning the environment conditions, day lighting is the best condition for the colors
and image tuning. Otherwise, use additional fluorescent light or its equivalent.
Tuning the Black Level and Column Balancing
To adjust Black level and Column balancing:
1 Start video by pressing the Start Video button in the toolbar.
2 Activate histogram by pressing h on the keyboard.
