Abstract
Abstract The character patterns of all kana (Japanese characters) or kanji (Chinese characters) to be displayed are divided substantially into halves in a horizontal direction (or alternately in a vertical direction) and stored in memory. Image codes corresponding to the divided character patterns thus obtained are assigned thereto, so that an image code is assigned to a corresponding portion of a kana or kanji. Accordingly, when the kana or kanji is displayed, the two image codes (character codes corresponding to the left and right sides of the same character) which are assigned to the above described character patterns are written to addresses of a buffer corresponding to the location on the screen the kana or kanji is to be displayed. Thus, the two portions of the kanji to be displayed are displayed in adjacent areas on the screen of a display device.
