摘要
An image display system provides a viewer with an experience of three-dimensional imagery by presenting a composite image made up of at least two separate images. The system includes at least first and second image sources, a beam combiner, and a “background-image-occluding element” which prevents background imagery from being seen through foreground image elements. The system presents the image from one of the image sources, containing background image information, at a distance from the viewer which is greater than the distance from the viewer to the other image presented from the other image source, which contains foreground image elements. The “background-image-occluding element” is positioned at the same optical distance from the viewer as the image containing foreground image elements, eliminating any parallax error between them, enabling the foreground image elements to always occlude appropriate areas of the background image, regardless of the viewer's position or the background image brightness relative to the brightness of foreground image elements.
