  • Patent number: 10547846
    Abstract: Image information is often transmitted from one electronic device to another. Such information is typically encoded and/or compressed to reduce the bandwidth required for transmission and/or to decrease the time necessary for transmission. Embodiments are directed to tagging objects or primitives with attribute tags to facilitate the encoding process. Other embodiments are directed to codecs running on hardware and/or software.

  • Patent number: 10506196
    Abstract: An embodiment may include a display processor, memory to store a 2D frame corresponding to a projection from a 360 video, and a quality selector to select a quality factor for a block of the 2D frame based on quality information from neighboring blocks of the 2D frame, including blocks which are neighboring only in the 360 video space. The system may also include a range adjuster to adjust a search range for the 2D frame based on a search area of the 2D frame, a viewport manager to determine if a request for a viewport of the 2D frame extends beyond a first edge of the 2D frame and to fill the requested viewport with wrap-around image information, and/or a motion estimator to estimate motion information based on both color information and depth information. Other embodiments are disclosed and claimed.

  • Publication number: 20190261000
    Abstract: Systems and methods may provide for occlusion detection in frame rate conversion. Detecting the occlusion allows frame rate conversion to be more accurately performed. In some embodiments, one or more stereoscopic depth cameras may be used to determine the depth of a moving object to more accurately determine the occlusion. In some embodiments, the compression ratio may be adjusted to balance the frame rate and power to help ensure compliance with a power budget. In at least some embodiments, the motion of a camera may be passed from a 3D render pipe to an encoder to avoid motion calculation and thereby saving power.

    Abstract: Systems, apparatuses and methods may a performance-enhanced computing system comprising a sensor for measuring luminance values corresponding to light focused onto the sensor at a plurality of pixel locations, a memory including a set of instructions, and a processor. The processor executes a set of instructions causing the system to generate a multi-segment tone mapping curve, generate a set of tone mapping values corresponding to the multi-segment tone mapping curve for equally spaced input values between zero and one for storage into a look up table, and process the luminance values using the look up table to apply the tone mapping curve to the luminance values of the pixels.

  • Publication number: 20180302556
    Abstract: Systems and methods may provide for capturing 360 degree video, and multi-resolution encoding, processing and displaying of the video based on a field of view (FOV) and region of interest (ROI) for a viewer. The ROI may be determined based on eye tracking information (ETI) and the video may be encoded for viewports within the FOV at a high resolution and for other viewports outside the FOV at a lower resolution. ROI in the video may be encoded at a high resolution and areas outside of the ROI may be encoded at a lower resolution. The ETI enables the selective display of one or more warnings based on the gaze of a user to improve the efficiency of the warning. 3D glasses having variable lens may be used to adjust the focal distance of a virtual display to match a virtual distance of an object based on stereo distance cues.

  • Publication number: 20180295367
    Abstract: Systems, apparatuses and methods may include a source device that generates a scene change notification in response to a movement of a camera, modifies an encoding scheme associated with the video content captured by the camera in response to the scene change notification, identifies a full-frame difference threshold, wherein scene analysis information includes frame difference data, and compares the frame difference data to an intermediate threshold that is less than the full-frame difference threshold, wherein the scene change notification is generated when the frame difference data exceeds the intermediate threshold. A sink device may obtain transport quality data associated with video content, modify an output parameter of a display based on the transport quality data, determine a view perspective of a still image containing a plurality of image slices, retrieve only a subset of the plurality of image slices based on the view perspective and decode the retrieved subset.

  • Publication number: 20180292743
    Abstract: Systems and methods may provide for utilizing stereoscopic inputs to take advantage of a codec to improve encoding and processing efficiency. The left and right channels of the stereoscopic inputs provide inputs for views of the same image frames. The frames may be offset by the parallax effect. The systems and methods utilize similarities between the left and right channels to allow motions (i.e., motion vectors) related to an object in the scene for one view to be spatially translated for the other view based on known differences in distance and geometry to avoid the necessity to encode and process both channel views. The system and method thereby improves the encoding and processing efficiency of motion processes such as motion vectors, motion sampling, macroblock sampling, edge sampling and the like.
