Abstract (en)

A method is disclosed for displaying characters using a computer system (1). A colour table (4) is pre-stored with 16 colours, eight of which are grey scale colours between and including black and white. Thus, if text or any other pre-set type of character is to be displayed the processor (2) works with the eigth grey scaled colours for anti-aliasing. for other characters, the other eight colours may optionally be used. Thus, efficient anti-aliasing is achieved without use of more processing power than conventionally required for processors using using a "VGA" colour table. Indeed, less is required because when dispaying text a three-bit code is sufficient instead of 4-bit.
