9.4 Area of Interest (AOI)
The area of interest (AOI) feature lets you specify a portion of the 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 sensor array. The top left corner is
designated as column 0 and row 0 as shown in Figure 29.
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 29.
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 6.10 on page 65.
