Description of the data path

Full binning
If horizontal and vertical binning are combined, every 4 pixels are consoli-
dated into a single pixel. At first two horizontal pixels are put together and
then combined vertically.
This increases light sensitivity by a total of a factor of 4 and at the same time
signal-to-noise separation is improved by about 6 dB. Resolution is reduced,
depending on the model.
Use Format_7 Mode_3 to activate full binning.
Sub-sampling
Sub-sampling is the process of skipping neighboring pixels (with the same
color) while being read out from the CCD chip.
All PIKE models, both color and b/w, have this feature.
Sub-sampling is used primarily for 2 reasons:
• A reduction in the number of pixels and thus the amount of data while
retaining the original image area angle and image brightness
Similar to binning mode the cameras support horizontal, vertical and h+v
sub-sampling mode.
Use Format_7 Mode_4 to activate horizontal sub-sampling. The different
sub-sampling patterns are shown below.
