Abstract
A time for displaying bitmap data is shortened, and the volume of a font table is reduced. A table having all records from start 0000h to end FFFFh is used as a pointer table which imparts a start address of bitmap data. A start address of bitmap data is stored in each of the records. Thereby, the character code directly accesses a corresponding record, to thus acquire a start address. Further, the volume of a font table is diminished by means of combined use, as pointer tables, of a first pointer table from which unused character code areas are removed and a second pointer table which specifies an address positional relationship between the respective character code areas achieved before removal and the respective character codes achieved after removal.
