Decimation
Decimation reduces the number of pixels in y-direction. Decimation can also be used together
with ROI or MROI. Decimation in y-direction transfers every n
th
row only and directly results in
reduced read-out time and higher frame rate respectively.
Fig. 4.26 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.

Figure 4.26: Decimation in full image
Fig. 4.27 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.

Figure 4.27: Decimation and ROI
Fig. 4.28 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.
