<p>A character pitch detecting apparatus is provided for use in a character segmenting system, and more particularly a character pitch detecting apparatus for detecting whether a character block which is a group of substantially lined characters printed on a paper and including merged characters is of a variable-pitch type or a fixed-pitch type. The character pitch detecting apparatus comprises a scanner (1), a character memory (2), a character block extractor (3), a character block register (4), a controller (6), a frequency table memory (5), an adder (11), an average-height detector (7), a multiplier (10), a width-range register (12), a width detector (13), a constant register (16), a register (8), and a decision circuit (9), which detects whether the character pitch in the character arrays stored in the memory (2) is variable or fixed.</p> |
