ABSTRACT:
A method and an apparatus are described for the recognition and reading of a bar code provided on an object and consisting of a plurality of code elements. The object carrying the bar code is scanned by one or more scanning beams of a bar code reader, wherein each time a scanning beam sweeps over an object a scan is formed and bright and dark regions of an object swept over during a scan are recognized as scanned elements. A width index is determined for at least some of the elements scanned during a scan and is in each case representative for the width of the element in the scanning direction. Furthermore the frequency of occurrence of the width indexes found is in each case determined and a conclusion is drawn on the presence of a bar code from the frequencies that are found.
