8.7 Decimation Vertical (acA2000-165 and
acA2040-90 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 acA2000-165 and acA2040-90 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 83.
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 84).
 2 for color cameras: only every second pair of rows
of the acquired frame will be transmitted out of the
camera (Figure 85).
By using the vertical decimation feature, you can increase the frame rate of the camera.
Setting Vertical Decimation
You can enable vertical decimation for the acA2000-165 and acA2040-90 cameras by setting the
Decimation Vertical parameter. The parameter value can be set to 1, 2, and 4. Setting the parameter
value to 1 disables vertical decimation.
