Abstract

PURPOSE: To compress the character pattern information, by coding the subpattern into variable length code according to the frequency of appearance taking into consideration the frequency of usage, in splitting the character pattern into subpattern and transmitting them into coding.
CONSTITUTION: The character pattern in 18×16 dots are separated into 24 sets of subpatterns in 3×4 dots. The frequency of appearance α1, α2,... at the characters. On the other hand, if the usage frequencies of each character are β1, β2..., the frequencies of appearance taking acount of the overall frequencies of appearance for each subpattern, that is, the frequencies of usage of character, can be obtained. This invention performs coding for long and short length for the subpatterns with the coding method of Hoffmann, based on the frequency of appearance.
