Abstract
A method of reading an optical code encodes a message that has a character chain having a plurality of characters. The method includes recording image data having the optical code; segmenting the image data to locate a region of interest having the optical code; evaluating the image data within the region of interest to read the message; and comparing the read characters of the message with at least one scheme that contains an expectation for at least one position of the message of a character at this position of the optical code to be read and thereby determining a scheme that matches the message and agrees with the read message in a minimum portion of the characters In this respect, a size of a region of interest in which an optical code fits is determined from the scheme and a new region of interest of this size is produced.
