ABSTRACT:
Systems and techniques for stitching together partial bar code segments to construct and decode information for a complete bar code. As a scanner operates to generate a scan pattern, information is maintained that can be used to identify a scan line being generated when an event of interest occurs. When a scan signal indicates that a terminal delimiter of a bar code is included in a bar code segment that has been transected by a scan line, information is noted that can identify the scan line. Subsequent transections of the bar code by the same scan line are noted, and information for overlapping bar code segments is stored. When a segment is detected that includes a delimiter opposite the delimiter appearing in the original segment, the stored information is retrieved and used to assemble the complete bar code.
