Abstract
The invention relates to a method for recording a bar code comprising a plurality of base elements. A reading device generates a sequence of partially overlapping images which together reproduce the bar code. Images are analysed to produce information which describes the positions of the base elements in each image. The bar code is then reconstructed by putting together information that has been extracted from the subimages, so that the contents of the bar code can be interpreted. In reconstruction, the position information and the images are used. By using the image information, the putting together process can be made less calculation-intensive. The invention also relates to a corresponding device and a corresponding computer program.
