Abstract
A video graphics system is provided with a framestore 3 and a viewing store 10. The framestore 3 is arranged to receive new image data created by a processor 6 in response to user manipulations of a stylus/touch tablet device 1. The framestore 3 and the viewing store 10 both have the capacity to store a high definition image and to facilitate display of the image on a high definition monitor 13 the framestore is arranged to transfer only portions of its data contents to the viewing store 10 during a frame period. The portion transferred is determined by the position of the stylus on the touch tablet at the beginning of a frame period. Data in the viewing store 10 is output in faster sequence for display on the monitor 13.
