Abstract:
In a bar code scanning system, a method for compiling element width information from multiple scans of a barcode label for use in decoding character information comprising:receiving a first scan of label information from a barcode label, the label information comprising bar element information and space element information; capturing from the first scan of label information element widths in relation to the bar element information and element widths in relation to the space element information; separately storing bar element widths captured from the first scan in a first histogram and storing space element widths captured. from the first scan in a second histogram; receiving a second scan of label information from the barcode label, the second scan of label information comprising bar element information and space element information; and repeating the steps of capturing element widths and separately storing bar element widths in the first histogram and storing space element widths in the second histogram for the second scan of label information received, wherein the bar element widths captured from the second scan of label information are combined with the bar element widths previously stored in the first histogram and the space element widths captured from the second scan of label information are combined with the space element widths previously stored in the second histogram.
