  • Patent number: 8446415
    Abstract: A framework for performing graphics animation and compositing operations has a layer tree for interfacing with the application and a render tree for interfacing with a render engine. Layers in the layer tree can be content, windows, views, video, images, text, media, or any other type of object for a user interface of an application. The application commits change to the state of the layers of the layer tree. The application does not need to include explicit code for animating the changes to the layers. Instead, an animation is determined for animating the change in state. The determined animation is explicitly applied to the affected layers in the render tree. A render engine renders from the render tree into a frame buffer for display on the processing device. Those portions of the render tree that have changed relative to prior versions can be tracked to improve resource management.

Layers in the layer tree can be content, windows, views, video, images, text, media, or other types of objects for an application's user interface. The application commits state changes to the layers of the layer tree. The application does not need to include explicit code for animating the changes to the layers. Instead, an animation is determined for animating the change in state by the framework which can define a set of predetermined animations based on motion, visibility, and transition. The determined animation is explicitly applied to the affected layers in the render tree. A render engine renders from the render tree into a frame buffer. Portions of the render tree changing relative to prior versions can be tracked to improve resource management.

  • Patent number: 7050642
    Abstract: A method and apparatus are disclosed for symmetrically compressing and decompressing video information in real time by coupling block and wavelet techniques. In the compression pipeline, the image is divided into blocks comprising 2k×2k pixels (in the preferred embodiment, k=1). The average color of each block is computed. The system computes an average luminance for each block and differential luminances of each pixel of the plurality of pixels of each block. A first plurality of frequency details of each block are determined by Haar transforming the differential luminances. The system computes an average color difference between each block and the preceding block, and quantizes the average color difference and the first plurality of frequency details using Lloyd-Max quantization. In an alternate embodiment, skip codes are generated for blocks having the same quantized average color difference and second plurality of frequency details.

  • Patent number: 6954193
    Abstract: A method and apparatus is described for providing a consistent visual appearance of pixels of a display screen with respect to a viewing position. Variations between perceived pixel level values associated with the pixels and corresponding pixel level values may be compensated for. Variations are associated with a viewing angle between pixel location and the viewing position and compensated for by applying a respective different correction factor to each of the corresponding pixel level values based on a respective viewing angle. Accordingly different non-linear correction curves corresponding to locations may be established relating a range of pixel level values to a corresponding range of corrected pixel level values associated with the viewing position. A calibration pattern may be further be displayed and user inputs associated with locations received responsive to calibration pattern.
