Setting the Auto Function AOI

By default, the auto function AOI is set to the full width of the sensor line and to a height of 128 lines.
You can change the size and the position of the auto function AOI by changing the value of the
following parameters:
AutoFunctionAOIOffsetX: determines the starting pixel (in horizontal direction) for the auto

function AOI. The outer left pixel is designated as pixel 0.
AutoFunctionAOIWidth: determines the width of the auto function AOI.

AutoFunctionAOIHeight: determines the number of lines that must be acquired for auto

function control.
All parameters can be set in increments of 1.
For general information about the parameters, see Section 8.5.1 on
When you are setting the auto function AOI, you must follow these guidelines:
Guideline
AutoFunctionAOIOffsetX + AutoFunctionAOIWidth
< width of camera sensor
AutoFunctionAOIHeight ≤ number of line acquisitions
Normally, the AutoFunctionAOIOffsetX and the AutoFunctionAOIWidth parameter
settings refer to the physical line of the sensor. But if binning is enabled, these
parameters are set in terms of a "virtual" line. For more information about binning,
see Section 8.7 on
Depending on your firmware version, you may be able to choose from multiple
auto function AOIs (AOI 1, AOI 2, ...) using the AutoFunctionAOISelector.
However, leave the Auto Function AOI 1 selected at all times and do not use the
other auto function AOIs.
You can set the parameter values for the auto function AOI from within your application software by
using the Basler pylon API:
// Select Auto Function AOI 1
camera.AutoFunctionAOISelector.SetValue(AutoFunctionAOISelector_AOI1);
// Set the position and size of the auto function AOI (sample values)
camera.AutoFunctionAOIOffsetX.SetValue(20);

Example: raL4096-80km
AutoFunctionAOIOffsetX + AutoFunctionAOIWidth
< 4096.
If AutoFunctionAOIHeight > number of line
acquisitions, the effective auto function AOI height will
be equal to the actual number of line acquisitions.
Example: If you set AutoFunctionAOIHeight to 400,
and acquire only 100 lines, the effective auto function
AOI height will be 100.
