Abstract
The invention pertains to an optical scanning system which is capable of reading the UPC (Universal Product Code) symbol, which is printed out of tolerance because the black bars are too wide and the white spaces are too narrow. The system provides an arrangement for selecting any one of three (3) modes of operation, wherein two (2) of the modes provide white space enhancement (a narrowing of the signals representative of the width of the black bars and a widening of the signals representative of the white spaces) and one (1) mode provides no enhancement at all.
