<p>A computer system having a processing unit (CPU) for controlling the drawing of images on a raster scan display screen having monitoring means (7,8) such as a line counter for monitoring the display of lines on the screen so the processing unit (CPU) can detect when a given line has been displayed so that, when a moving image is to be displayed, the processing unit (CPU) is able to schedule the drawing operation to maximise the time available for the image to be re-drawn before it is displayed again or to ensure there is sufficient time to re-draw the image before it is displayed again, and so reduce perceived flicker of the moving image. <IMAGE></p> |
