    Abstract: A method and system for calibration and compensation of color in a three dimensional display system includes user calibration of individual color channels using a multiplicity of grey screens while viewing with three dimensional glasses. Look-up tables are generated to ease conversion of input pixels to color corrected pixels to pre-distort the color of the pixels being driven by the three dimensional display system. Input pixels are then converted using the look-up tables and color corrected frames are displayed to a user. The pre-distortion effect allows a user to perceive colors in the three dimensional system as intended with the distortions caused by the viewing glasses and other aspects of the three dimensional display system.

  • Patent number: 9317483
    Abstract: A method for resampling time series data includes determining a first time series of data points; determining a variation of the data points within a selected sequence, wherein the variation is determined by determining linearly interpolated data points for the data points of the selected sequence and by determining a maximum absolute difference. If a determined variation is greater than a predetermined error value, subsequences are selected by repeatedly dividing the first time series into adjacent subsequences until the first time series comprises a set of subsequences, wherein a determined variation for each of the subsequences is smaller than the predetermined error value. A resampled time series is created by adding the data points of the first time series that correspond to a first or last data point of the selected subsequences to the resampled time series, wherein every data point is added only once to the resampled time series.

  • Patent number: 9007389
    Abstract: Embodiments of the present invention are directed towards increasing texture filtering performance for texel components represented by more than 8 bits. As the number of bits per component increases, the number of texels that are processed each clock cycle decreases since more bits need to be processed to produce each filtered result. A filtered result may be accumulated over two or more iterations, with each iteration producing a portion of the filtered result. When only a portion of the components for each texel are used, the unused texel components are not processed. Elimination of unnecessary texel processing for unused texel components may improve texture filtering performance.

  • Patent number: 9007388
    Abstract: Surfaces without a global surface coordinate system are divided into surface regions having local surface coordinate systems to enable the caching of surface attribute values. A surface attribute value for a surface region may include contributions from two or more adjacent surfaces. Sample points may be arranged at the corners, rather than centers, of surface regions and include prefiltered values based on two or more surfaces. A renderer may sample the surface attribute function using these prefiltered values without accessing any adjacent surfaces, even if the renderer's filter crosses a surface boundary. A multiresolution cache stores surface attribute values at different resolution levels for surface regions of one or more surfaces, which may be discontiguous. Two or more resolution levels may have the same number of sample points but have values based on filters with different areas and spatial frequency limits. Resolution levels may be selected based on geodesic distance on a surface.

    Abstract: The efficiency of shading and rendering processes can be improved through implementing object oriented programming for shading program languages. Computer graphics data representing a geometric model in a scene are determined and assigned to object oriented classes and subclasses and are subsequently sorted and grouped into several (e.g., two or more) groups based on the classification information. Once the computer graphics data are assigned in a class and/or subclasses and grouped, a shader interpreter implements SIMD operators on each group of data values.

  • Patent number: 8933958
    Abstract: Embodiments of enhanced user interface elements in ambient light are described. Sensor inputs can be received from light sensors that detect ambient light proximate an integrated display of a portable device. A determination is made that the ambient light detracts from the visibility of user interface elements displayed in a user interface on the integrated display. Display properties of graphic components of a user interface element are interpolated through a light range from approximately complete darkness to full sunlight, and the graphic components of a user interface element can be modified based on interpolating the display properties within the light range to enhance the visibility of the user interface element for display in the ambient light.

  • Patent number: 8917284
    Abstract: This patent relates to thin plate spline (TPS)-based interpolation techniques for representing free-flowing vector graphics (VG) images based on user-specified features, such as points and curves. One or more features can be identified in a pixel grid. A higher-order least squares interpolating function with a TPS smoothness objective can then be utilized to interpolate individual color values to individual pixels of the pixel grid. Smoothness terms of the function that impose smoothness penalties can be interrupted in certain regions of the pixel grid based on attributes of the user-specified features. For example, a curve attribute can specify a particular color value(s), add or remove a smoothness penalty, or anisotropically impose a first derivative constraint in a particular direction.

    Abstract: An image processing apparatus and an image processing method are provided. When a display apparatus is in the 3D display mode, a mode-switching unit adjusts the way to generate a vertical-count-value by counting every two rows of pixels and outputs the adjusted vertical-count-value. A dither unit outputs a carry value corresponding to the adjusted vertical-count-value. An adding unit adds the carry value and the surplus pixel bit together.

  • Patent number: 8907973
    Abstract: An image processor includes generates a content adaptive kernel from an image block with noise of a luminance component signal with a low resolution. The content adaptive kernel is convolved with the luminance component signal. A noise signal and an extracted texture which excludes noise are generated. The luminance component signal is filtered as function of the noise signal to generate an enhanced luminance component signal. Horizontal and vertical scaling is performed on the enhanced luminance component signal, the extracted texture, and the luminance component signal, with the luminance component signal adaptively scaled as a function of the extracted texture. The horizontally and vertically scaled enhanced luminance component signal, extracted texture and luminance component signal are then combined to generate an output luminance component signal with a high resolution.

  • Patent number: 8907971
    Abstract: A global image adjustment, such as dynamic range adjustment is established based on image characteristics. The image adjustment is based more heavily on pixel values in image areas identified as being important by one or more saliency mapping algorithms. In one application to dynamic range adjustment, a saliency map is applied to create a weighed histogram and a transformation is determined from the weighted histogram. Artifacts typical of local adjustment schemes may be avoided.
