  • Patent number: 10599028
    Abstract: A sphere assembly comprises a set or network of curved and triangularly-shaped transparent panels (2) placed next to one another to form a spherical shape of a sphere (1), a set of project films (3) placed on the transparent panels, and a set of connectors (4) for connecting the adjacent curved transparent panels to one another. The sphere assembly may be positioned so that the sphere assembly is held and placed in a secure and well-balanced position for the virtual reality (VR), augment reality (AR), or mixed reality (MR) gameplay or environment. The projection films can receive images or sensory cues from a set of projectors which project images from the VR, AR, or MR environment to the sphere assembly. The projectors may connect upstream to at least one image processing module which receives and processes image information from a player's headset, controller, and other tracking sensors.

The first anamorphic lens has a red transparent color filter for removing blue light, forming a red color filter image of the object. The second anamorphic lens has a blue transparent color filter for removing red light, forming a blue color filter image of the object.

  • Patent number: 6108130
    Abstract: A stereoscopic image sensor may be formed of a single image sensor having a pair of fields formed therein. The fields may be closer to one another than are a pair of left and right image collectors. The close spacing may be achieved by using an image redirector to redirect image information from the spaced apart collectors to the less spaced apart fields on the image sensor. In some embodiments of the present invention, by using a single imaging sensor, a more compact structure may be achieved which may be of lower cost and may enjoy reduced processing complexity. In addition, because a single sensor is utilized, in some embodiments of the present invention, the left and right images may be captured essentially identically.

    Abstract: An apparatus for presentation of apparent three-dimensional images without special viewing glasses is disclosed. A projection system projects right and left stereo images from a stereoscopic slide so that the right stereo image and the left stereo image become superimposed relative to one another on a viewing screen. The viewing screen comprises light transmissive slit-raster members and a light diffusion member. The viewing screen is adapted to allow the right and left stereo images to pass between the opaque raster members and be perceived only by the right and left eyes, respectively, of the viewer as the left image formed in a raster-like manner on the diffusion member is blocked by further opaque raster members and prevented from being perceived by the right eye and the right stereo image also formed in a raster-like manner on the diffusion member is blocked by the further opaque raster members and prevented from being perceived by the left eye.
