Patent abstract

A two dimensional symbol is decoded by forming a binary image that includes the symbol. The binary is used to generate symbol margins for use in digitization. By using the binary image to determine the symbol margins, margins can be located efficiently and in the presence of symbol contrast variation caused by irregularities in the marked surface or light source angles. Digitization proceeds based on the determined margins.
