Vignetting
For Matrix 120 readers 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
Field of View.
Figure 62 – MP Model Vignetting Effect
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.
