7.9 Decimation
The decimation feature lets you perform vertical and/or horizontal sub-sampling of an acquired
frame.
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).
 When vertical decimation is used, vertical binning is not available. When
horizontal decimation is used, horizontal binning is not available.
However: When vertical decimation is used, horizontal binning is available.
When horizontal decimation is used, vertical binning is available.
For more information about decimation, see Section 7.9.1 on page 253.
 When decimation is used, scaling is not available.
For more information about scaling, see Section 7.10 on page 258.
