Figure 12: Maximum ROI
If the ROI is set to the size of the visible portion of the zoomed image as shown in Figure 13 and
the image is tilted to the maximum limits as shown in Figure 14, pixels will not be dropped from
the ROI but the AGC will change as the ROI changes with the pan and tilt coordinates. The AGC
is determined only by the visible portion of the image.
