The settings use
an X-Y coordinate system with (0,0) being at the
center of the sensor array. The upper two numbers

are the pixel coordinates of the upper

remain centered on the zoom window. If the camera is being used in zoom mode, it is
recommended that the zoom AGC ROI be set to the same size as the zoom window.
