A bar code reader includes an image capture means for storing a two dimensional image in memory, which stored image may include a bar code symbol within the field of view of said image. The present bar code reader further includes method and apparatus for determining the location and orientation of said bar code symbol within the field of view of said image, and then filtering said located and oriented bar code symbol along an axis perpendicular to said detected orientation. Thereafter, the filtered bar code symbol is scanned and applied to a decoder to produce a decoded bar code output.
