<p>PROBLEM TO BE SOLVED: To provide a method and device with which the decodable display of a one-dimensional(1D) or two-dimensional(2D) bar code symbol while using a bar code reader having only a 1D image sensor. SOLUTION: When a reader 10 is asynchronously moved across the symbol of an object to be read, continuous 1D digital display is generated. This display is practically inspected in real time and when the symbol is a 1D symbol 72, it is immediately decoded. When the symbol is not the 1D symbol, it is inspected whether this display has one of variously different 2D finder patterns or not and when any finder is identified, concerning that finder, a 2D symbol 76 is decoded.</p> |
