5.1.4
Decimation (monochrome cameras)
Decimation reduces the number of pixels in y-direction. Decimation in y-direction transfers
every n
th
row only and directly results in reduced read-out time and higher frame rate
respectively.
Decimation can also be used together with ROI or MROI. In this case every ROI
should have a height that is a multiple of the decimation setting. E.g. if decima-
tion=3, then the height of every ROI should be a multiple of 3.
Fig. 5.6 shows decimation on the full image. The rows that will be read out are marked by red
lines. Row 0 is read out and then every n
th
row.

Fig. 5.7 shows decimation on a ROI. The row specified by the Window.Y setting is first read out
and then every n
th
row until the end of the ROI.
Fig. 5.8 shows decimation and MROI. For every MROI region m, the first row read out is the row
specified by the MROI<m>.Y setting and then every n
th
row until the end of MROI region m.
