    • 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.
    • 本文公开了一种字符识别处理,其提取由字符图案信息的笔画包围的白色区域,并且通过确定打开所述白色区域的方向来识别字符。 该处理由处理装置提供,用于网格信息的转换,以便在一个扫描周期期间将存在于两个黑色网格点之间的白色网格点转换为黑色网格点,以在一个方向上扫描所述字符图案信息。 基于由处理装置获得的转换后的字符图案信息来确定白色区域的开口方向。
