Abstract
A barcode decoding method includes obtaining a plurality of scanning lines defining a second set of scanning lines which also comprises a predetermined scanning line. Each scanning line has a first set of pixels, each identified by a first and by a second index. The pixels that are part of the second set of scanning lines define a third set of pixels and, from the pixels of the third set of pixels, it is possible to select a fourth set of pixels to construct an oversampled profile of the barcode, ordering intensity values calculated from the intensity values of the pixels of the fourth set. The pixels of the fourth set include pixels of the predetermined scanning line and further pixels of the third set that do not belong to the predetermined scanning line, to obtain a subpixel resolution that is able to decode the barcode.
