Method and apparatus for reading under sampled bar code symbols
The present invention is directed to a method for reading a bar code symbol with an optical reader. The method includes the step of scanning the bar code symbol to obtain a plurality of scan lines. Each of the plurality of scan lines includes a linear array of N-pixel values. Adjacent pixels in the linear array of N-pixel values are separated by a sample separation distance. A reconstructed scan line is generated that interleaves the N-pixel values from selected scan lines of the plurality of scan lines. A reconstructed pixel sample separation distance of adjacent interleaved pixels is an integer fraction of the pixel sample separation distance.
