    Abstract: To enable HDR video signals of a plurality of signal interfaces to be satisfactorily handled. A processing unit processes a linear high dynamic range video signal and obtains a high dynamic range video signal that has undergone a grayscale compression process. The processing unit is able to perform grayscale compression processes of a plurality of signal interfaces. For example, when a grayscale compression process of another signal interface other than a reference signal interface is performed, the processing unit further performs a process of adding characteristics of system gamma of the reference signal interface and a process of cancelling out characteristics of system gamma of the other signal interface.

  • Patent number: 11211036
    Abstract: Systems, apparatuses, and methods for implementing a timestamp based display update mechanism. A display control unit includes a timestamp queue for storing timestamps, wherein each timestamp indicates when a corresponding frame configuration set should be fetched from memory. At pre-defined intervals, the display control unit may compare the timestamp of the topmost entry of the timestamp queue to a global timer value. If the timestamp is earlier than the global timer value, the display control unit may pop the timestamp entry and fetch the frame next configuration set from memory. The display control unit may then apply the updates of the frame configuration set to its pixel processing elements. After applying the updates, the display control unit may fetch and process the source pixel data and then drive the pixels of the next frame to the display.

  • Patent number: 11164365
    Abstract: A graphics processing system has a rendering space which is divided into tiles. Primitives within the tiles are processed to perform hidden surface removal and to apply texturing to the primitives. The graphics processing system includes a plurality of depth buffers, thereby allowing a processing module to process primitives of one tile by accessing one of the depth buffers while primitive identifiers of another, partially processed tile are stored in another one of the depth buffers. This allows the graphics processing system to have “multiple tiles in flight”, which can increase the efficiency of the graphics processing system.

  • Patent number: 11116420
    Abstract: Physicians performing invasive procedures utilize instruments inserted into a human body to perform the procedures. Such procedures typically involve actions to be performed on specific targeted anatomical structures. During the procedure, nearby anatomical structures unrelated to the procedure should generally be avoided. A system and techniques are provided herein for monitoring the position of such unrelated nearby anatomical structures relative to one or more surgical instruments. The system emits a warning to a human operator such as a surgeon if one of the instruments is too close to a monitored anatomical structure.
