  • Patent number: 11335042
    Abstract: Methods, systems, and non-transitory computer readable storage media are disclosed for utilizing enhanced curve primitives to modify color gradients in vector-based graphics. To illustrate, the disclosed system can receive an input of a curve to insert into a portion of a vector-based graphic including a mesh for a color gradient. The disclosed system can then insert a discontinuity into the mesh by adding a plurality of vertices to the mesh defining two unconnected edges at the position of the curve within the portion of the vector-based graphic. After inserting the discontinuity into the mesh, the disclosed system can determine colors for the edges of the discontinuity based on one or more user-selected colors and/or one or more colors associated with the color gradient. The disclosed system can then update the color gradient in response to determining the colors for the edges of the discontinuity.

  • Patent number: 11310540
    Abstract: In one example, a device includes one or more processors implemented in circuitry and configured to execute a Dynamic Adaptive Streaming over HTTP (DASH) aware application (DAA) and a DASH client, and one or more user interfaces. The DAA subscribes to DASH events of a DASH event stream via a first application programming interface (API) between the DAA and a DASH client executed by the one or more processors. The DAA then receives data for one or more DASH events of the DASH event stream from the DASH client via a second API between the DAA and the DASH client, the data for the one or more DASH events specifying interactivity-related content. The DAA then presents the interactivity-related content via the one or more user interfaces. The DAA may further send usage measurements on usage of the interactivity-related content to the DASH client, for reporting to a report server device.

  • Patent number: 11145266
    Abstract: A method and a circuit for viewing-angle image compensation applied to a flat panel display are provided. A viewing-angle image compensation scheme is applied to an input image for improving a problem of color shift caused by a large viewing angle. The method further solves the blur effect in high frequency regions and color bleeding in low saturation regions of the input image after viewing-angle image compensation. In the method, a frequency distribution of the input image is detected and decremental frequency weights are assigned to the regions having high to low frequencies. A saturation distribution of the input image is detected and incremental saturation weights are assigned to the regions having high to low saturations. The weights assigned to the regions are used to designate degrees of the viewing-angle image compensation. The method can effectively reduce the effect of the viewing-angle image compensation on the image.

Parameters for the multiple color mapping functions can be encoded into a bitstream. In one embodiment, color mapping functions are consecutively applied on their own domains of definition only. In another embodiment, the first color mapping (CRI1) is applied on its domain of definition only, but the second color mapping is applied only on samples that have been previously color mapped by CRI1 and which are also inside the domain of definition of the second color mapping function. At the decode side, the multiple color mapping functions can be reconstructed and successively applied to a decoded picture to generate another picture.

  • Patent number: 10764547
    Abstract: A projection system projects images onto a projection surface in, for example, a computer game head-mounted display (HMD). The light is projected through a spatial light modulator that is combined with a Freeform Fourier Lens that is a combination of a Fresnel lens, an X-phase grating, a Y-phase grating, and a radial grating. The freeform lens causes the gradual shrinking of portions of the laser-projected image, decreasing the perceived pixel pitch in at least one foveal area on the projection surface compared to a non-modulated laser image. The center positions of the Fresnel lens and radial grating can be changed in the X and Y axes, moving the condensed foveal areas in accordance with eye tracking of the user. In effect, the system projects a Foveated image that contains variable pixel pitch such that a user perceives a higher visual acuity in his gaze direction.

  • Patent number: 9997134
    Abstract: Methods and systems for calibrating devices reproducing high dimensional data, such as calibrating High Dynamic Range (HDR) displays that reproduce chromatic data. Methods include mapping input data into calibrated data using calibration information retrieved from spatial data structures that encode a calibration function. The calibration function may be represented by any multidimensional scattered data interpolation methods such as Thin-Plate Splines. To efficiently represent and access the calibration information in runtime, the calibration function is recursively sampled based on guidance dataset. In an embodiment, an HDR display may be adaptively calibrated using a dynamic color guidance dataset and dynamic spatial data structures.

  • Patent number: 9699468
    Abstract: An adaptive screen and video coding system adaptively selects different coding schemes for coding an image block of a screen or video image based on a type of content included in the image block. The adaptive screen and video coding system further includes a screen coding scheme that classifies pixels of the image block into major colors and escape pixels and convert values of the pixels into index values assigned to the major colors and the escape pixels. Since the number of index values is usually less than a normal range of pixel values, using the index values instead of actual pixel values further facilitate compression and coding of the image block, thus improving coding accuracy and efficiency of the screen or video image. In one embodiment, the adaptive screen and video coding system may be used for screen sharing application.

    Abstract: An RGB video signal is generated by illuminating an object with light from a first monitor and capturing an image of the object with a camera. The second monitor holds a profile representing the correspondence relationship between R, G, and B values generated by displaying an image including values of R, G, and B on a reference monitor and capturing an image of the displayed image with the camera and X, Y, and Z values which are measurements of tristimulus values of the displayed image in the XYZ color space. The second monitor converts the first R, G, and B values of the video signal to first X, Y, and Z values based on the profile, and converts the first X, Y, and Z values to second R, G, and B values appropriate for the second monitor to display an image of the object on a display unit.

  • Patent number: 9659513
    Abstract: A method for use with an electronic signboard (e.g., an LED signboard) compensates psychovisual chromaticity shift due to ambient light. The method first measures a color of light reflected from the signboard. Based on the measurement a set of calorimetric equations defining the desired light to be perceived as being displayed by each pixel of the signboard are solved. The calorimetric equations are the additive color mixture of the ambient light and the light to be actually displayed by the pixel in the absence of ambient light. The calorimetric equations may be expressed in units of uniform color space. The solutions of the colorimetric equations are then used to control the light actually displayed by the pixel.

  • Patent number: 9641820
    Abstract: Techniques for de-noising a digital image using a multi-band noise filter and a unique combination of texture and chroma metrics are described. A novel texture metric may be used during multi-band filter operations on an image's luma channel to determine if a given pixel is associated with a textured/smooth region of the image. A novel chroma metric may be used during the same multi-band filter operation to determine if the same pixel is associated with a blue/not-blue region of the image. Pixels identified as being associated with a smooth blue region may be aggressively de-noised and conservatively sharpened. Pixels identified as being associated with a textured blue region may be conservatively de-noised and aggressively sharpened. By coupling texture and chroma constraints it has been shown possible to mitigate noise in an image's smooth blue regions without affecting the edges/texture in other blue objects.
