  • Patent number: 9824485
    Abstract: Presenting a view based on a virtual viewpoint in a three dimensional (3D) scene. The 3D scene may be presented by at least one display, which includes displaying at least one stereoscopic image of the 3D scene by the display(s). The 3D scene may be presented according to a first viewpoint. A virtual viewpoint may be determined within the 3D scene that is different than the first viewpoint. The view of the 3D scene may be presented on the display(s) according to the virtual viewpoint and/or the first view point. The presentation of the view of the 3D scene is performed concurrently with presenting the 3D scene.

  • Patent number: 9736466
    Abstract: System and method for video processing. First video levels for pixels for a left image of a stereo image pair are received from a GPU. Gamma corrected video levels (g-levels) are generated via a gamma look-up table (LUT) based on the first video levels. Outputs of the gamma LUT are constrained by minimum and/or maximum values, thereby excluding values for which corresponding post-OD display luminance values differ from static display luminance values by more than a specified error. Overdriven video levels are generated via a left OD LUT based on the g-levels. The overdriven video levels correspond to display luminance values that differ from corresponding static display luminance values by less than the error threshold, and are provided to a display device for display of the left image. This process is repeated for second video levels for a right image of the stereo image pair, using a right OD LUT.

  • Patent number: 9706191
    Abstract: In some embodiments, a system for tracking with reference to a three-dimensional display system may include a display device, an image processor, a surface including at least three emitters, at least two sensors, a processor. The display device may image, during use, a first stereo three-dimensional image. The surface may be positionable, during use, with reference to the display device. At least two of the sensors may detect, during use, light received from at least three of the emitters as light blobs. The processor may correlate, during use, the assessed referenced position of the detected light blobs such that a first position/orientation of the surface is assessed. The image processor may generate, during use, the first stereo three-dimensional image using the assessed first position/orientation of the surface with reference to the display.

  • Patent number: 9681122
    Abstract: Systems and methods for enhancement of a coupled zone of a 3D stereoscopic display. The method may include determining a size and a shape of the coupled zone. The coupled zone may include a physical volume specified by the user's visual depth of field with respect to screen position of the 3D stereoscopic display and the user's point of view. Content may be displayed at a first position with a virtual 3D space and the first position may correspond to a position within the coupled zone. It may be determined that the content is not contained in the coupled zone or is within a specified distance from a boundary of the coupled zone and, in response, display of the content may be adjusted such that the content has a second position in the virtual 3D space that corresponds to another position within the coupled zone.

  • Patent number: 9554126
    Abstract: Systems and methods for navigating a 3D stereoscopic scene displayed via a 3D stereoscopic display system using user head tracking. A reference POV including a reference user head position and a reference user head orientation may be established. The user head POV may be tracked, including monitoring user head positional displacements and user head angular rotations relative to the reference POV. In response to the tracking, a camera POV used to render the 3D stereoscopic scene may be adjusted based on a non-linear mapping between changes in the camera POV and the user head positional displacements and user head angular rotations relative to the reference POV. The non-linear mapping may include a mapping of user head positional displacements relative to the reference POV to translational movements in the camera POV and a mapping of user head angular rotations relative to the reference POV to rotations in the camera POV.

  • Patent number: 9549174
    Abstract: Systems and methods for a head tracked stereoscopic display system that uses light field type data may include receiving light field type data corresponding to a scene. The stereoscopic display system may track a user's head. Using the received light field type data and the head tracking, the system may generate three dimensional (3D) virtual content that corresponds to a virtual representation of the scene. The stereoscopic display system may then present the 3D virtual content to a user. The stereoscopic display system may present a left eye perspective image and a right eye perspective image of the scene to the user based on the position and orientation of the user's head. The images presented to the user may be updated based on a change in the position or the orientation of the user's head or based on receiving user input.
