1. A method for reading a bar code symbol with an optical reader, the method comprising:

  • scanning the bar code symbol to obtain a plurality of scan lines, each of the plurality of scan lines including a linear array of N-pixel values, adjacent pixels in the linear array of N-pixel values being separated by a sample separation distance; and

    generating a reconstructed scan line that interleaves the N-pixel values from selected scan lines of the plurality of scan lines, whereby a reconstructed pixel sample separation distance of adjacent interleaved pixels is an integer fraction of the pixel sample separation distance.
