Abstract

Smoother transitions between changing cursor images which are less stressful to the interactive user of a computer controlled display are provided by apparatus for changing the cursor image, including a frame buffer for storing the display screen image as a pixel array, a separate display buffer for storing the current cursor image as a pixel array, together with apparatus for storing an alternate cursor image as a pixel array during the display of the current cursor image, and means for replacing the current cursor image with the alternate cursor image. In raster scan apparatus for maintaining screen images in the frame buffer on said display screen, there are means for effecting the replacement of said cursor images during a vertical blanking period in said raster scanning.
