ABSTRACT:
An image display apparatus includes a conversion circuit which makes 1-bit information in display memory correspondence to a plurality of dot data on the display screen, so that more sophisticated image information than the ability of a display device is expanded into a bright/dark dot pattern. The apparatus enables an application display program oriented to a higher-graded display device to be displayed in a pseudo sense on a lower-graded display device.
