Abstract
A stack barcode reader may include an imager configured to image the stack barcode; an image memory configured to store an image datum of the stack barcode; and a data processor including a decoder configured to decode an encoded information expressed as the stack barcode, on the basis of the image datum. The decoder may be configured to measure width of a bar and a space of the stack barcode; measure a T-sequence, being a sequence of numerical values, according to line width of a bar and a space of the stack barcode; obtain a code-word corresponding to the T-sequence; and compare a cluster value obtained from the T-sequence with a theoretical cluster value, and modify the T-sequence by using the theoretical cluster value and the conversion table of T-sequence/code-word if there appears a difference between the two cluster values.
