摘要： A method and apparatus for decoding one or more bar codes comprising a plurality of marks, the marks comprise one or more spaces and one or more bars. The method comprises the following steps: digitalizing electrical signals obtained from a pick-up for picking up reflected laser beams; deriving the width of bars and spaces from the digital signals; determining one or more mark values with a degree on the basis of the width of the spaces and bars found inside the mark or in the immediate vicinity of the mark; determining one or more information values with a degree from the mark values with a degree; and selecting the most probable information values for a bar code or part of a bar code using the determined information values.

摘要： An optional device for reading and decoding bars of different reflectivity arranged in accordance with a barcode and adjoining one another. The device includes an optical scanning device for scanning the bars by a light beam, a sensor for receiving the reflected light beam and converting the latter into an electrical sensor output signal, a transition detector for detecting the level transitions of the electrical sensor output signal and a decoding device which decodes the scanned barcode on the basis of the output signals from the transition detector. The sensor output signal is fed to an amplitude averaging device and/or contrast averaging device, the output of which is connected to a decision device which controls the decoding device in such a way that reading and decoding of the barcode is carried out several times if the output signal from the amplitude averaging device and/or contrast averaging device is below at least a predetermined threshold value.
