Binning (only Oscar F-510C)
2xBinning
Definition 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.
Only Format_7 Binning is possible only in video Format_7. The type of binning used
depends on the video mode.
Types 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.
