Reading Features
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 Vertical 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.
