Reading Distance

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.
