11.6 Area of Interest (AOI)
The area of interest (AOI) feature lets you specify a portion of the imaging sensor array and after
each image is acquired, only the pixel information from the specified portion of the array is
transmitted to the host PC.
The area of interest is referenced to the top left corner of the array. The top left corner is designated
as column 0 and line 0 as shown in Figure 44.
The location and size of the area of interest is defined by declaring an X offset (coordinate), a width,
a Y offset (coordinate), and a height. For example, suppose that you specify the x offset as 10, the
width as 16, the y offset as 6, and the height as 10. The area of the array that is bounded by these
settings is shown in Figure 44.
The camera will only transfer pixel data from within the area defined by your settings. Information
from the pixels outside of the area of interest is discarded.

One of the main advantages of the AOI feature is that decreasing the height of the AOI can increase
the camera’s maximum allowed acquisition frame rate.
For more information about how changing the AOI height affects the maximum allowed frame rate,
see Section 8.9 on page 102.
