ABSTRACT:
Disclosed is a system for automatic adjustment of character spacing suited to characters in innumerable combinations, such as in the case with Chinese characters and hiragana and katakana characters in the Japanese language. In character dot data of a plurality of characters which construct a character string developed in memory, character density data representing the broadness of the character face of a character, character face overlap area data representing degree of overlap between this character and a character adjacent thereto in a state in which the character and adjoining character are closest to each other, and blank-space area data representing the broadness of blank space produced between the two characters are generated for each and every character. The appropriate character spacing is inferred for each character through fuzzy reasoning by applying the character density data, character face overlap area data and blank-space area data to already given knowledge relating to character spacing adjustment.
