摘要：
A system for decoding a bar code symbol receives a signal representative of the symbol and searches the signal in one dimension to locate two adjacent critical points corresponding to an element of the symbol. The system also computes a value representative of the signal energy between the two critical points and determines the width of the element in accordance with the value.
