7.10 Image Area of Interest (AOI)
The image area of interest (AOI) feature lets you specify a portion of the imaging sensor array and
after each frame is acquired, only the pixel information from the specified portion of the array will be
transmitted to the host PC.
The size of the area of interest is defined by declaring a width in columns of pixels and a height in
lines of pixels. Once you set the width and height of the AOI, the camera will automatically position
the AOI at the center of the sensor.
For example, suppose that you specify the width as 20 columns and the height as 16 lines. The size
and position of the AOI will be as shown in Figure 35. (Note that the size of the sensor in the figure
is for illustration only. It does not represent the actual size of the sensor in the camera.)
