DecimationHorizontal – Integer – R/W
Decimation (also known as sub-sampling) is the process of skipping neighbor-
ing pixels (with the same color) while being read out from the CCD chip. Deci-
mationHorizontal controls the horizontal sub-sampling of the image. There is
no increase in the frame rate with horizontal sub-sampling.
DecimationVertical – Integer – R/W
Decimation (also known as sub-sampling) is the process of skipping neighbor-
ing pixels (with the same color) while being read out from the CCD chip. Deci-
mationVertical controls the vertical sub-sampling of the image. There is
increase in frame rate with vertical sub-sampling.
Note

• BinningY and DecimationVertical are mutually exclu-
sive. Setting BinningY > 1 forces DecimationVertical to
1.
• Color cameras only: Color information is lost while bin-
ning is active due to summing of adjacent different fil-
tered pixels on the Bayer filter array.
Range: [1–8] Default: 1
1 Off
2 2x reduction factor. 2 of 4 columns displayed
4 4x reduction factor. 2 of 8 columns displayed
8 8x reduction factor. 2 of 16 columns displayed
Note

• Writing an invalid number for DecimationHorizontal will
round up to next valid mode. For example, 5 rounds up to
8.
• DecimationHorizontal and BinningX are mutually exclu-
sive. Setting DecimationHorizontal > 1 forces BinningX
to 1.
