Considerations When Using Binning - Basler ace acA640-90gm User Manual

You can combine vertical and horizontal binning. This, however, may cause objects to appear dis-
torted in the image. For more information on possible image distortion due to combined vertical and
horizontal binning, see below.
Setting Binning
You can enable vertical binning by setting the Binning Vertical parameter. Setting the parameter's
value to 2, 3, or 4 enables vertical binning by 2, vertical binning by 3, or vertical binning by 4 respec-
tively. Setting the parameter's value to 1 disables vertical binning.
You can enable horizontal binning by setting the Binning Horizontal parameter. Setting the param-
eter's value to 2, 3, or 4 enables horizontal binning by 2, horizontal binning by 3, or horizontal bin-
ning by 4 respectively. Setting the parameter's value to 1 disables horizontal binning.
You can set the Binning Vertical or the Binning Horizontal parameter value from within your
application software by using the Basler pylon API. The following code snippet illustrates using the
API to set the parameter values:
// Enable vertical binning by 2
Camera.BinningVertical.SetValue( 2 );
// Enable horizontal binning by 4
Camera.BinningHorizontal.SetValue( 4 );
// Disable vertical and horizontal binning
Camera.BinningVertical.SetValue( 1 );
Camera.BinningHorizontal.SetValue( 1 );
You can also use the Basler pylon Viewer application to easily set the parameters.
For more information about the pylon API and the pylon Viewer, see Section 3 on
10.6.1

Considerations When Using Binning

Increased Response to Light
Using binning can greatly increase the camera's response to light. When binning is enabled, ac-
quired images may look overexposed. If this is the case, you can reduce the lens aperture, reduce
the intensity of your illumination, reduce the camera's exposure time setting, or reduce the camera's
gain setting.
When using vertical binning, the limits for the minimum gain settings are automatically lowered. This
allows you to use lower gain settings than would otherwise be available.
For the lowered limits for the minimum gain settings, see Section 10.1 on
