Abstract
A method for use in processing an analog signal from a laser scanning bar code reader containing information representative of reflected light from indicia including regions of different light reflectivity, and including narrow and wide elements of the same reflectivity of the indicia, by locating edge transitions between narrow and wide elements; estimating the edge shift associated with such transitions; and changing the edge position to correct for convolution distortion.
