9.3.6 ABR3106-WPxx 1.2 MP + Polarized Models 2D Codes
Vignetting
For ABR 3000 models used in 2D code reading applications, due to
the "fisheye" or “vignetting” effect of the lens, the reading area is
limited to the central zone of the Vertical FOV.
Depending on the application, Image Cropping can be applied 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.
