4.3.1 User-specicColor Adjustment
The user-specic color adjustment in Baumer color cameras facilitates adjustment of the
correction factors for each color gain. This way, the user is able to adjust the amplica-
tion of each color channel exactly to his needs. The correction factors for the color gains
range from 1 to 4�

4.3.2 OnePushWhiteBalance
Here, the three color spectrums are balanced to a single white point. The correction fac-
tors of the color gains are determined by the camera (one time).

4.4.1 Offset/Black Level
On Baumer cameras, the offset (or black level) is adjustable from 0 to 16 LSB (relating
to 8 bit).
Notice
The given values refer to the digital Offset.
The analog offset works automatically and is not adjustable.

4.4.2 Gain
In industrial environments motion blur is unacceptable. Due to this fact exposure times
are limited. However, this causes low output signals from the camera and results in dark
images. To solve this issue, the signals can be amplied by a user-dened gain factor
within the camera. This gain factor is adjustable from 1 to 10.
Notice
Increasing the gain factor causes an increase of image noise.

AutoGain:
Some models of the EXG
series are equipped with
the ability for automatic ad-
justment of the gain factor
by means of target-settings
in respect of the intensity of
the recorded images.
