ABSTRACT:
A bar code reader locates and decodes a bar code symbol in a pixel image by searching along a selected scan line for a candidate quiet zone and then counting the bright/dark transitions that correspond to candidate bars and spaces. The reader determines whether the candidate quiet zone and candidate bars and spaces correspond to a bar code symbol, and, if so, decodes the symbol. When processing binary pixel images, the reader searches for candidate quiet zones and counts bright/dark transitions by analyzing the image one byte of pixels at a time.
