A graphics processing system is provided. The graphics processing system comprises a display unit, a frame buffer, an interface, and a controller. The frame buffer, defined by an initial pointer and a boundary pointer first image data in the frame buffer, stores first image data corresponding to a first image area displayed on the display unit. The interface receives a scrolling request directing the first image to scroll in a vertical and/or horizontal direction. The controller determines a reading pointer of the frame buffer according to the initial and boundary pointers and the scrolling request, loads new image data into a memory location at which a particular part of the first image data is stored. The new image data is loaded in a memory location in which an image area not included in the first image area after the scrolling is stored, retrieves the remaining first image data and the new image data beginning from the reading pointer, and directs the display unit to display the retrieved image data in sequence on a viewable image area thereof.
