  • Patent number: 10812823
    Abstract: Systems and methods for improving operational efficiency of a video encoding system used to encode image data are provided. In embodiments, the video encoding system includes a low resolution pipeline that includes a low resolution motion estimation block, which generates downscaled image data by reducing resolution of the image data and performs a motion estimation search using the downscaled image data and previously downscaled image data. The video encoding system also includes a main encoding pipeline in parallel with the low resolution pipeline that includes a motion estimation block, which determines a global motion vector based on data from the low resolution motion estimation block. The main encoding pipeline may utilize the global motion vector in determining a candidate inter prediction mode.

  • Patent number: 10789902
    Abstract: An electronic device may generate content that is to be displayed on a display. The display may have an array of liquid crystal display pixels for displaying image frames of the content. The image frames may be displayed with positive and negative polarities to help reduce charge accumulation effects. A charge accumulation tracker may analyze the image frames to determine when there is a risk of excess charge accumulation. The charge accumulation tracker may analyze information on gray levels, frame duration, and frame polarity. The charge accumulation tracker may compute a charge accumulation metric for entire image frames or may process subregions of each frame separately. When subregions are processed separately, each subregion may be individually monitored for a risk of excess charge accumulation.

  • Patent number: 10706825
    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: 10694129
    Abstract: Systems and methods for down-scaling are provided. In one example, a method for processing image data includes determining a plurality of output pixel locations using a position value stored by a position register, using the current position value to select a center input pixel from the image data and selecting an index value, selecting a set of input pixels adjacent to the center input pixel, selecting a set of filtering coefficients from a filter coefficient lookup table using the index value, filtering the set of source input pixels to apply a respective one of the set of filtering coefficients to each of the set of source input pixels to determine an output value for the current output pixel at the current position value, and correcting chromatic aberrations in the set of source input pixels.

  • Patent number: 10602152
    Abstract: Adaptive video processing for a target display panel may be implemented in or by a server/encoding pipeline. The adaptive video processing methods may obtain and take into account video content and display panel-specific information including display characteristics and environmental conditions (e.g., ambient lighting and viewer location) when processing and encoding video content to be streamed to the target display panel in an ambient setting or environment. The server-side adaptive video processing methods may use this information to adjust one or more video processing functions as applied to the video data to generate video content in the color gamut and dynamic range of the target display panel that is adapted to the display panel characteristics and ambient viewing conditions.

  • Publication number: 20200058152
    Abstract: A mixed reality system that includes a device and a base station that communicate via a wireless connection The device may include sensors that collect information about the user's environment and about the user. The information collected by the sensors may be transmitted to the base station via the wireless connection. The base station renders frames or slices based at least in part on the sensor information received from the device, encodes the frames or slices, and transmits the compressed frames or slices to the device for decoding and display. The base station may provide more computing power than conventional stand-alone systems, and the wireless connection does not tether the device to the base station as in conventional tethered systems. The system may implement methods and apparatus to maintain a target frame rate through the wireless link and to minimize latency in frame rendering, transmittal, and display.

  • Patent number: 10438561
    Abstract: Systems and methods for interpolating overdrive values using a lookup table to compensate for potential display artifacts. Interpolating includes applying a first interpolation type to a first portion of the lookup table when a point to be interpolated is in the first portion of the lookup table. However, interpolating includes applying a second interpolation type to a second portion of the lookup table when the point to be interpolated is in the second portion of the lookup table. The interpolated values are then used to drive pixels of a display panel.

  • Patent number: 10403192
    Abstract: Devices and methods for error diffusion and spatiotemporal dithering are provided. By way of example, a method of operating a display includes receiving a pixel input, a set of pixel coordinates, and a current frame number. A kernel and a particular kernel bit of the kernel is selected from a set of kernels, based upon the pixel input, the pixel coordinates, the frame number, or any combination thereof. A dithered output is determined based at least in part upon the kernel bit. When the display is in a diamond pixel configuration, the dithered output is applied in accordance with a diamond pattern formed by red, blue, or red and blue pixel channels.

  • Publication number: 20190208205
    Abstract: A method of signaling additional chroma QP offset values that are specific to quantization groups is provided, in which each quantization group explicitly specifies its own set of chroma QP offset values. Alternatively, a table of possible sets of chroma QP offset values is specified in the header area of the picture, and each quantization group uses an index to select an entry from the table for determining its own set of chroma QP offset values. The quantization group specific chroma QP offset values are then used to determine the chroma QP values for blocks within the quantization group in addition to chroma QP offset values already specified for higher levels of the video coding hierarchy.
