ABSTRACT:
Disclosed herein is a character recognition process which extracts white regions surrounded by strokes of character pattern information and recognizes characters by determining the directions in which said white regions are opened. The process is provided by processing apparatus, for conversion of mesh information, disposed so as to convert a white mesh point present between two black mesh points to a black mesh point during one scanning period for scanning said character pattern information in one direction. The directions of openings of the white regions are determined based on the converted character pattern information obtained by the processing apparatus.
