Abstract
Method and apparatus are provided for scanning an optically readable code such as a bar code at a variable scanning velocity. Such variable velocity scanning has the effect of normalizing the density of code elements to be scanned thereby eliminating the need for the scanner operator during the course of bar code decoding to vary the distance between the scanner and the optical code for a predetermined range of code element densities.
