A first lens is provided for focusing light reflected from a graphical code to form a first image on a first region of the image sensor. A second lens is provided for focusing light reflected from the graphical code to form a second image on a second region of the image sensor. The first lens is separated from the image sensor by a first distance, and the second lens is separated from the image sensor by a second distance.
