2.4.2 Sub-sampling Decimation
Subsampling reduces the number of pixels output by reducing the output frame size,
but maintains the full field of view. If an area of interest (AOI) is selected, then the
field of view of the AOI is maintained.
The C5180, C4181, C4180 and C2880 employ a ‘keep one pixel’, ‘skip one pixel’
sequence. When enabled in both x and y, every other pixel within a line is retained
and every other line within the image is retained.
