<p>A stereoscopic image acquisition and display system is provided. The system includes a mechanism for displaying imagery either three-dimensionally or two-dimensionally. The mode of operation of the display can be selected automatically or under control of the observer, so as to avoid presenting image pairs which are not conveniently fused into a three-dimensional image by the observer. In an autostereoscopic embodiment of the system the observer's location is tracked and viewing zones are positioned to remain colocated with the eyes of the observer. If the observer moves outside the tracking range of the system, the imagery defaults to a two-dimensional presentation. The system may also include means for sensing the distance from a stereo-camera, which provides the two perspectives required for three-dimensional viewing, to the object field. When the distance to this field is less than a preset minimum, the imagery defaults to a two-dimensional presentation, to avoid parallax beyond the comfortable level.</p> |
