7.9.1 Decimation Vertical (acA3800-14 and
acA4600-10 Only)
The decimation vertical feature lets you specify the extent of vertical sub-sampling of the acquired
frame, i.e. you can define rows that you want to be left out from transmission.
The acA3800-14 and acA4600-10 cameras support
decimation in vertical direction.
Examples
(Blue rows will be transmitted):
If vertical decimation is set to
1: the complete frame will be transmitted out of the

camera (no sub-sampling is realized); see
Figure 97.
This is valid for mono and color cameras.
2 for mono cameras: only every second row of the

acquired frame will be transmitted out of the camera
(Figure 98).
2 for color cameras: only every second pair of rows

of the acquired frame will be transmitted out of the
camera (Figure 99).
