ABSTRACT:
Video image information representing an immersive image up to a complete spherical field of view is utilized by a special image processor to extract a region of interest as a moveable window. The immersive image is divided into standardized pentagonal segments according to the geometry of the dodecahedron, and these segments are carried as a plurality of video channels. The image processor extracts and assembles the moveable region of interest from among the various segments of the image as they are recorded in a segmented memory, according to pointing device information from the user, such as a joystick or the tracker of a head-mounted-display. The video image information used can come from sources including a photographic camera system recording scenes from the real world, and can be either live or prerecorded. Existing methods for transmission of video channels can be used to broadcast such immersive images. A special encoding of pentagon information can be used to conserve bandwidth and reduce the number of channels required, or to add information for a stereoscopic effect. independently movable windows within a single overall spherical video image input can be produced when more than one viewing processor is used.
