Abstract

An augmented display (20) includes an image display (22) and a silhouette display source (26). The image display generates a virtual image (26) to be received by the viewer. The silhouette disply source occurs in the path of background light (16). The silhouette display source generates a mask corresponding to the image content of the image display. The mask is a darkened area reducing or blocking background light. As the light from the virtual image is overlaid onto the background, there is less background light in the portion where the image appears.
