Reading Width
Due to the "fisheye" effect of the wide angle
6 mm lens, the reading area for higher
resolution codes is limited to the central zone
of the Vertical Field of View.
For these applications, window cropping is
recommended above and below the central
zone of the Vertical FOV, limiting image
acquisition to the effective reading area and
therefore increasing frame rate and reducing
overall image processing time. See par. 7.5.8.
