Sub-sampling (Stingray b/w and color)
What is sub-sampling?
Definition
Sub-sampling is the process of skipping neighboring pixels (with the same
color) while being read out from the CCD chip.
Which Stingray models have sub-sampling?
All Stingray models, both color and b/w, have this feature.
Description of sub-sampling
Sub-sampling is used primarily for the following reason:
•
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.
Format_7 Mode_4
By default and without further remapping use Format_7 Mode_4 for
•
b/w cameras:
2 out of 4 horizontal sub-sampling
•
color cameras: 2 out of 4 horizontal sub-sampling
The different sub-sampling patterns are shown below.
