Patent number: 6985290Abstract: Three-dimensional imaging without parallax barriers or specialized eye gear, and without attendant loss of resolution, is provided by a display that produces dynamic images for display on at least two stacked electronic transmissive displays to create a continuous 3-D image field in a large viewing area or in multiple viewing areas. The images on each display are derived from stereoscopic image sources corresponding to both eyes of a viewer, and the derived images act as a mask for each other causing 3-D perception. The derived images are processed by summing the predicted image data, comparing the predicted image data to the desired stereopair, and minimizing the error. In preferred embodiments, the processing can be performed by an artificial neural network. A viewer may be presented with different aspects of an image as their viewing position changes to allow the viewer to perceive various perspectives of an image in dynamic fashion.Type: GrantFiled: January 6, 2004Date of Patent: January 10, 2006Assignee: NeurOK LLCInventors: Andrey N.
