  • Patent number: 10395336
    Abstract: A computing system comprises graphics rendering logic and image processing logic. The graphics rendering logic processes graphics data to render an image using a rendering space which is sub-divided into a plurality of tiles. Cost indication logic obtains a cost indication for each of a plurality of sets of one or more tiles of the rendering space, wherein the cost indication for a set of one or more tiles is suggestive of a cost of processing rendered image values for a region of the rendered image corresponding to the set of one or more tiles. The image processing logic processes rendered image values for regions of the rendered image. The computing system causes the image processing logic to process rendered image values for regions of the rendered image in dependence on the cost indications for the corresponding sets of one or more tiles.

  • Patent number: 10380712
    Abstract: A graphics processing system comprises a memory that stores graphics data. The graphics data stored in the memory is accessible using virtual memory addresses that map to physical memory addresses in the memory. The graphics processing system further comprises page merging circuitry configured to use metadata provided for a set of graphics data to determine whether any pages of the set of graphics data are similar to each other. The pages of the set of graphics data that are determined as being similar to each other are merged by mapping the virtual memory addresses for those pages to the same physical memory address in the memory. The page merging process can provide a way to reduce the number of physical memory addresses needed to store the pages of the set of graphics data in the memory.

  • Patent number: 10263908
    Abstract: The processing of search queries for a customer using a set of resource can balance performance with cost, in order to ensure that the processing satisfies customer performance requirements while attempting to minimize the cost to the customer for obtaining that performance. In addition to dynamically updating the allocation of resources used to process the requests, such as to change the number or sizes of allocated resources, the number of indexes to be searched can be updated as well. For example, a search index can be divided into two sub-indexes against which queries can be executed concurrently in order to reduce the latency by about a half. Adjustments to the indexes and resources can be balanced to minimize cost while retaining performance, which can include rejoining sub-indexes or reducing the number of resource as appropriate.

    Abstract: Video processing techniques and pipelines that support capture, distribution, and display of high dynamic range (HDR) image data to both HDR-enabled display devices and display devices that do not support HDR imaging. A sensor pipeline may generate standard dynamic range (SDR) data from HDR data captured by a sensor using tone mapping, for example local tone mapping. Information used to generate the SDR data may be provided to a display pipeline as metadata with the generated SDR data. If a target display does not support HDR imaging, the SDR data may be directly rendered by the display pipeline. If the target display does support HDR imaging, then an inverse mapping technique may be applied to the SDR data according to the metadata to render HDR data for display. Information used in performing color gamut mapping may also be provided in the metadata and used to recover clipped colors for display.

The rendering target is a graphics surface that is marshaled to the remote terminal. A PDU (Protocol Data Channel) is produced over this first graphics surface that includes a mapping of the location of the top-level window. A second graphics surface containing transparency information is created for a top-level window that contains a transparency characteristic. This second graphics surface is encoded and marshaled to the remote terminal separately from the first graphics surface.

  • Patent number: 9936199
    Abstract: Compared to traditional gamma-coded video, perceptually quantized video provides greater flexibility for the transmission and display management of high-dynamic range video, but it does not compresses as efficiently using existing standard codecs. Techniques are described to improve the coding efficiency of perceptually coded video by applying a color cross-talk transformation after the RGB/XYZ to LMS transformation. Such a transform increases luma and chroma correlation for color appearance models, but improves perceptual uniformity and overall coding efficiency for wide color gamut, HDR, signals.

  • Patent number: 9906817
    Abstract: Coding circuitry may implement an indexed set of color values that stores color values for a neighbor pixel group. The coding circuitry may obtain a current pixel group for coding. The coding circuitry may code the current pixel group using the indexed set of color values when an indication that there is a compression advantage to coding using the indexed set of color values is present within an input stream. When the indication is not present, the coding circuitry may code the current pixel group using another coding technique.

  • Patent number: 9904461
    Abstract: A method for selecting the text on a remote computer or a server from a mobile device is provided. Actions of a user for selecting a text area on the mobile device are emulated on a remote server. A user initiates text selection on a mobile device using touch screen functionality, which is reflected on selected elements of a remote server. Once the mobile device user completes the selection, the emulator selects a corresponding area of the server screen. All mobile device user actions related to selection of text area are emulated on a remote server.

  • Patent number: 9899007
    Abstract: The device and method described in this application relate generally to graphics processing systems utilizing the tile based rendering technique and more specifically relate to the processing of the framebuffer data in graphics processing applications. The present invention discloses techniques to reduce the bandwidth needed to access the color data stored in the framebuffer. A method for adaptive lossy delta based compression of color data is disclosed. The error rate, that is the amount of color data lost during the lossy compression process, is controlled by various parameters of the rendered tiles produced by the graphics processing system. The compression process is driven by a dedicated unit which enables informed compression decisions with controllable error rate so as the output color data can be reliably decompressed to produce the original color data with minimal or no errors.

  • Patent number: 9832440
    Abstract: The present technology relates to a reproduction device, a reproduction method, and a recording medium capable of displaying graphics with a broader dynamic range of luminance and appropriate brightness. The reproduction device reads a Tone_map stream and a graphics stream of an extended graphics from a recording device, wherein the recording device records the Tone_map stream including HDR information indicating a luminance feature of the extended graphics which are first graphics with a first luminance range different from and broader than a second luminance range, and a luminance conversion definition information used in luminance conversion from the extended graphics to standard graphics. The standard graphics are graphics with the second luminance range. The reproduction device converts the extended graphics into the standard graphics based on the luminance conversion definition information of the extended graphics included in the Tone map stream.

  • Patent number: 9788004
    Abstract: A method of coding a block of video data using palette coding is disclosed. According to the present invention, when a previous block is available, the system receives first information related to a previous palette set corresponding to previous palettes/triplet palette, and second information related to a previous palette predictor set corresponding to previous palette predictors/triplet-palette predictors associated with the previous block. The system then derives a current palette predictor set corresponding to current palette predictors/triplet-palette predictor associated with the current block based on the previous palette set and the previous palette predictor set by including at least one unused color or triplet of the previous palette predictor set in the current palette predictor set. A current palette set corresponding to current palettes/triplet-palette associated with the current block is derived from the current palette predictor set for palette encoding or decoding.
