Claims
- 1. A scanner for reading a coded symbology on an object, comprising:scanning means for repetitively scanning coded symbology and for providing a scan signal producing a series of counts corresponding to transitions in at least fragments of the coded symbology; data means coupled to said scanning means and responsive to said scan signal of said scanning means for selectively storing said counts; comparing means coupled to said data means for comparing stored counts from successive scan signals; and registration means coupled to said data means for reconstructing at least a portion of said coded symbology using the stored counts from at least two of said fragments of said coded symbology.
- 2. A method for reading a coded symbology on an object, comprising the steps of:repetitively scanning said coded symbology and obtaining a series of counts corresponding to transitions in at least fragments of said coded symbology; selectively recording said fragments of said coded symbology based on comparisons of stored counts from successive scan signals; and reconstructing at least a portion of said coded symbology from stored counts corresponding to transitions in at least two of said fragments of said code.
