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, Image 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 
“Image Cropping” on page 148.
