Binning reduces resolution by combining adjacent same-color imager pixels to produce
one output pixel. All of the pixels in the FOV contribute to the output image in bin mode.
This can result in a more pleasing output image with reduced subsampling artifacts. It
also improves low-light performance. For columns, the combination step can be either
an averaging or summing operation. Depending on lighting conditions, one or the other
may be desirable. In low-light conditions, summing produces a gain roughly equivalent
to the column bin factor. Column summing may be enabled by setting Column_Sum.
Binning works in conjunction with skipping. Pixels that would be skipped because of the
Column_Skip and Row_Skip settings can be averaged instead by setting Column_Bin
and Row_Bin to the number of neighbor pixels to be averaged with each output pixel.
For example, to set bin 2x mode, set Column_Skip and Column_Bin to 1. Additionally,
Column_Start must be a multiple of (2 * (Column_Bin + 1)) and Row_Start must be a
multiple of (2 * (Row_Bin + 1)).
