Area Of Interest (Aoi) - Basler A202K Manual

Operation and Features

3.7 Area of Interest (AOI)

The area of interest (AOI) feature allows you to specify a portion of the CCD array and during
operation, only the pixel information from the lines included in the AOI is transferred out of the
camera.
The size of the area of interest is defined by declaring a starting column, a width in columns, a
starting line and a height in lines. For example, if you specify the starting column as 11, the width
in columns as 16, the starting line as 5 and the height in lines as 10, the AOI will be as shown in
Figure 3-12.
