Abstract: A graphic scrolling apparatus comprising a unit for storing image data; an image display device having a screen for displaying a first predetermined-sized area of the image data stored in the image data storing unit; a buffer memory for temporarily storing a second predetermined-sized area of the image data stored in the image data storing means, the second predetermined-sized area being larger than the first predetermined-sized area; a first depicting unit for retrieving, from the image storing means, at least image data corresponding to a third area of the first predetermined-sized area, which protrudes from the second predetermined-sized area and for depicting the at least image data corresponding to the third area on a fourth area of the second predetermined sized area, which is in the outside of the first predetermined-sized area as the first predetermined-sized area scrolls on the second predetermined-sized area; and an image display controlling unit for controlling the apparatus such that an image is d

Abstract: In a text display apparatus comprising a display panel having the display resolution fixed, and a program for carrying out text display by the standard character size corresponding to the display resolution of the display panel, a text display apparatus displaying one page of text in the entire area of the screen with a character size different from the standard character size without modifying the application program, and a method of displaying text are disclosed.

Abstract: An image display apparatus is disclosed, in which a programmable counter is provided with a separate counter with the output thereof varied cyclically with the counting of horizontal sync signal pulses, the output of the counter is used to cull out the horizontal sync signal pulses supplied to the programmable counter, and pixel data of the same line is read out from a reflesh memory at least twice in a period, in which the input is culled. A display on a display panel having a fixed display resolution thus is obtained of display data of a lower resolution than the fixed display screen resolution.
