Abstract

PURPOSE:To enlarge characters at an optional magnification with a simple constitution by providing an interpolation processing table where interpolation processings to all of 512 kinds of turn-on/off pattern information to which a local pattern detecting means can output are recorded. CONSTITUTION:A local pattern detecting means 12 detects the ON/OFF pattern information of an optional dot and adjacent 8 dots on a character pattern storage means 11, and an interpolation processing selecting means 13 is provided with an interpolation processing table 22 where instructions of interpolation processing methods corresponding to 512 kinds of possible ON/OFF pattern information are stored. An interpolation processing determining means 21 supplies a control signal, which instructs that the interpolation processing method corresponding to ON/OFF pattern information should be performed, to a dot interpolating means 15. Positions of dots on the character pattern storage means 11 and an instructed magnification are inputted to an enlargement magnification discriminating means 14 to calculate the enlargement rate. The dot interpolating means 15 enlarges the center dot and performs the interpolation processing to output an enlarged character pattern.
