Abstract
An autostereoscopic display provides true natural perception of 3D scenes by projecting depth-slice images of objects located at different distances, so during each video frame the scene is segmented into five or more different depths and then each displayed in succession with both the stereo disparity and apparent image distance proper for each depth.
Claims18
A binocular 3D projection system comprising dual projectors each dynamically creating a succession of depth-slices fully comprising a 3D scene, wherein each pair of said depth slices has a stereoshift and is displayed in the form of a pair of images at a selected apparent distance from the observer, the parameters of said stereo-disparity and apparent distance being that of the object-distance to be binocularly displayed to the observer.
A binocular 3D projection system comprising:
- dual image projectors, each said projector comprising an image display, an optical element of variable power, and an electronics driver, said driver successively generating image-segments of a 3-D input scene, each said image-segment representing a depth-slice of said 3-D input scene, parsed into their different distances from said observer, and said driver in operation causing the optical element of variable power to alter its overall power such that each said depth-slice is displayed in the form of an image having an appropriate apparent distance from an observer.
A 3D projection system comprising:
- a display;
- an optical system including an element of variable optical power arranged to form an image of the display visible from a viewpoint at an apparent distance from the viewpoint dependent on the power of the element of variable optical power;
- and
- a driver operative to control the display and the element of variable optical power so as to produce a plurality of said visible images at different apparent distances from the viewpoint at a rate sufficiently fast to be perceived by normal human vision as a single image having depth.
