Binning is the process of combining neighboring pixels while being read out 
from the CCD chip.

Binning is used primarily for 3 reasons:

•

a reduction in the number of pixels and thus the amount of data while 
retaining the original image area angle

•

an increase in the frame rate (vertical binning and full binning only)

•

a brighter image, also resulting in an improvement in the signal-to-
noise ratio of the image

Signal-to-noise ratio (SNR) and signal-to-noise separation specify the 
quality of a signal with regard to its reproduction of intensities. The value 
signifies how high the ratio of noise is in regard to the maximum achievable 
signal intensity.

The higher this value, the better the signal quality. The unit of measurement 
used is generally known as the decibel (dB), a logarithmic power level. 6 dB 
is the signal level at approximately a factor of 2.

However, the advantages of increasing signal quality are accompanied by a 
reduction in resolution.

Binning is possible only in video Format_7. The type of binning used 
depends on the video mode. 

In general, we distinguish between the following types of binning
(H=horizontal, V=vertical):

•

2 x H-binning

•

2 x V-binning

Only Oscar F-510C has the binning feature.

Changing binning modes involves the generation of new 
shading reference images due to a change in the image size.
