Abstract
A code reading device is equipped with a region extracting unit 2, which divides a photographed image of a bar code into a plurality of horizontal areas, and extracts readable regions from the horizontal areas respectively, and a region coupling unit 4, which couples the extracted regions to restore the whole bar code. Even if an unreadable portion occurs in a part of the bar code, a plurality of readable regions are extracted as parts of the barcode and those regions are coupled to restore a bar code the entirety of which can be read. Consequently, it is possible to accurately read a bar code having dirt or containment of illumination light partially.
