Abstract
A graphics display system comprises a monitor (5); a first frame store (1) for holding digital data defining the color content of an image to be displayed on the monitor; a second frame store (2) for holding an array of control data, there being a control data value corresponding to each pixel of the image in the first frame store; and a processor (6,10,3) to cause the monitor to display the image in the first frame store under control of the control data array. The processor (6,10,3) means is adapted to cause a moving contrast image to be mixed with the image from the first frame store (1) under control of the control data array.
