4.1.8 BrightnessCorrection(BinningCorrection)
The aggregation of charge carriers may cause an overload. To prevent this, binning cor-
rection was introduced. Here, three binning modes need to be considered separately:
Binninig Realization
1x2 1x2 binning is performed within the sensor, binning correction also takes
place here. A possible overload is prevented by halving the exposure time.
2x1 2x1 binning takes place within the FPGA of the camera. The binning cor-
rection is realized by aggregating the charge quantities, and then halving
this sum.
2x2 2x2 binning is a combination of the above versions.

4.1.9 FastMode
The Fast Mode is employed in 90% of all cases.
Here you can use the full frame rate of the camera. Short readout times cause a de-
crease in the smear effect.
4.1.10 HQMode
In HQ Mode the pixel clock of the sensor is mottled. This leads to longer readout times
and enhances the signal-to-noise ratio (SNR). Hereby the image quality is increased.
