Abstract
When display data are written into the terminal's display memory, the data indicative of the display coordinate are converted from the normalized values to the absolute values of the NTSC system or system and are then written into the corresponding addresses of the display memory, so that regardless of the fact that the display is of the NTSC system or of the system, the figure can be displayed with the correct aspect ratio. Further, when the coordinates are converted, the conversion is carried out such that the display resolution is regarded as the highest one, so that even if the resolution of the display is increased by increasing the capacity of the display memory, it is not necessary to change the conversion algorithm. For displays having less than full resolution capability, the display data is scaled by omitting some of the converted data when writing it into the display memory.
