    Abstract: A method of producing vertically projecting three-dimensional images using virtual 3D models (22), wherein said 3D models (22) are created by the simultaneous localization and depth-mapping of the physical features of real objects. A camera (17) is used to take a first image (22A) from a first perspective, and a subsequent image (22N) from a subsequent perspective, wherein the autofocus system (18) provides a first set of depth mapping data and a subsequent set of depth mapping data. The first set of depth mapping data and the subsequent set of depth mapping data are used to generate a disparity mapping (21). A virtual 3D model (32) is created from the disparity mapping (21). The virtual 3D model (32) is imaged to obtain images that can be viewed as three-dimensional. Enhanced 3D effects are added to the virtual 3D model (32).

    Abstract: The invention is directed to recording, transmitting, and displaying a three-dimensional image of a face of a user in a video stream. Reflected light from a curved or geometrically shaped screen is employed to provide multiple perspective views of the user's face that are transformed into the image, which is communicated to remotely located other users. A head mounted projection display system is employed to capture the reflective light. The system includes a frame, that when worn by a user, wraps around and grips the user's head. Also, at least two separate image capture modules are included on the frame and generally positioned relatively adjacent to the left and right eyes of a user when the system is worn. Each module includes one or more sensor components, such as cameras, that are arranged to detect at least reflected non-visible light from a screen positioned in front of the user.

    Abstract: Enables real-time depth modifications to stereo images of a 3D virtual reality environment locally and for example without iterative workflow involving region designers or depth artists that includes re-rendering these images from the original 3D model. Embodiments generate a spherical translation map from the 3D model of the virtual environment; this spherical translation map is a function of the pixel shifts between left and right stereo images for each point of the sphere surrounding the viewer of the virtual environment. Modifications may be made directly to the spherical translation map, and applied directly to the stereo images, without requiring re-rendering of the scene from the complete 3D model. This process enables depth modifications to be viewed in real-time, greatly improving the efficiency of the 3D model creation, review, and update cycle.

    Abstract: A compressed light field imaging system is described. The light field 3D data is analyzed to determine optimal subset of light field samples to be (acquired) rendered, while the remaining samples are generated using multi-reference depth-image based rendering. The light field is encoded and transmitted to the display. The 3D display directly reconstructs the light field and avoids data expansion that usually occurs in conventional imaging systems. The present invention enables the realization of full parallax 3D compressed imaging system that achieves high compression performance while minimizing memory and computational requirements.
