Abstract:
A method for decoding a coded symbology having differing symbol widths representing encoded information, the method comprising:generating scanned data representing a line crossing the coded symbology;identifying individual symbol widths of the coded symbology based on in part a run length series of values of the scanned data;decoding the scanned data based on in part the identified symbol widths to determine resolvable portions of the encoded information;determining characteristics of the scanned values associated with each differing width corresponding to the resolvable portions; anddecoding the scanned data corresponding to portions of the encoded information which were not determined to be resolvable based on in part the width characteristics; andwherein the step of decoding the not resolvable encoded information is based on in part comparing for each identified symbol width in the not resolved portions with a width for that symbol determined based on in part the width characteristics.
