ABSTRACT:
A postal code detection system is described having a prescanning apparatus operable to detect the position on a mail item of a postal code. The pre-scanning apparatus detects word length, character height of each word, and word position. Based on the latter detected information and on a set of predetermined rules of postal code placement, the postal code can be identified to the exclusion of all other words on the mail item, and its position can be identified and sent to the main scanner and recognition circuitry.
