11.1.11 Brightness Correction (Binning Correction)
The summation of pixel values may cause an overload. To prevent this, binning correction
was introduced.
Binninig Realization
2x1 2x1 binning takes place within the FPGA of the camera. The binning cor-
rection is realized by averaging the pixel values instead of simply adding
them.
11.2 Color Adjustment – White Balance
This feature is available on all color cameras of the Baumer HXG series and takes
place within the Bayer processor.
White balance means independent adjustment of the three color channels, red,
green and blue by employing of a correction factor for each channel.
User-specific 11.2.1 Color Adjustment
The user-specific 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 amplifica -
tion of each color channel exactly to his needs. The correction factors for the color gains
range from 1 to 4.

One Push 11.2.2 White Balance
Notice
Due to the internal processing of the camera, One Push White Balance refers to the
current ROI but always considers the entire row.
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).
