Matrix 120™ 210-0xx 2D Codes WVGA
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 Ver-
tical Field of View.

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.
