Abstract:

A system and method for character presence detection having the capability of locating characters within a line of characters represented by a binary stream of data bits. The stream of binary data bits is divided into scans which correspond to scans of a photocell array. The system for character presence detection receives the binary stream. Each data bit has a unique position within its particular scan, which corresponds to the selection of a particular photocell of the photocell array as the output thereof, and, therefore, the binary stream of data bits comprises an image corresponding to alphanumeric characters disposed upon a written medium. That is, the data bits comprise an image of characters which form a line disposed along a written medium. Within the binary stream, some data bits represent character information and the remainder represents background information. The system compares each scan to a plurality of criterion, each criterion being unique, and forms a series of character segments and spaces based on the results of the comparison of each scan to each of the criterion.
