10.3 Image Area of Interest (AOI)
The image area of interest (Image AOI or AOI for short) 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 will be read out of the sensor and transmitted from the camera.
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 48.
The location and size of the area of interest is defined by declaring an offset X, a width, an offset Y,
and a height. For example, suppose that you specify the offset X as 10, the width as 16, the offset Y
as 6, and the height as 10. The area of the array that is bounded by these settings is shown in Figure
48.
The camera will only transmit 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 size of the AOI can increase
the camera’s maximum allowed acquisition frame rate.
The AOI feature also includes Center X and a Center Y capabilities. When Center X is enabled, the
camera will automatically center the AOI along the sensor’s X axis (and will disable the Offset X
