<p>The method for reconstructing a bar code through consecutive scans comprises the following steps: a) carrying out at least one scan of the bar code; b) determining a reconstructed wave form representative of said at least one scan; c) carrying out an actual scan of the bar code; d) determining an actual wave form representative of said actual scan; e) aligning said reconstructed and actual wave forms; f) combining said aligned wave forms by updating said reconstructed wave form with said actual wave form. The method can directly operate on the photo-sensor signal before carrying out any digitization of it. <IMAGE></p> |
