Abstract (en)
[origin: WO9829860A1] The present invention is directed to systems and methods for synthesizing a three-dimensional video stream from a two-dimensional video source. A frame (48) from the two-dimensional video source is digitized (50) and split (54) into a plurality of fields (56, 58). Each field contains a portion of the information in the frame. The fields are then separately processed and transformed (60, 62) to introduce visual clues that, when assembled with the other fields, will be interpreted by a viewer as a three-dimensional image. Such transformations can include, but are not limited to, skewing transformation, shifting transformations, and scaling transformations. The transformations may be performed in the horizontal dimension, the vertical dimension, or a combination of both. In many embodiments the transformation and reassembly of the transformed fields is performed within a single frame so that no temporal shifting is introduced or utilized to create the synthesized three-dimensional video stream. After the three-dimensional video stream has been synthesized, it is displayed on an appropriate display device. Appropriate display devices include a multiplexed display device which alternates the viewing of different fields in conjunction with a pair of shuttered glasses which allows one field to be displayed to one eye of viewer and another field to be displayed to another eye of a viewer. Other types of single display devices and multidisplay devices may also be used.
