  • Patent number: 7692666
    Abstract: Systems and techniques support color management of an image with a parameterized image color space. In general, in one implementation, a color profile that conforms to a defined color profile architecture and that defines a multistage color space transform is generated. The image includes a parameterized encoding of an image color space with image parameters defining a range and an offset of an image component of the image, and a white point of the image color space. Generation of the color profile involves affecting two or more stages of the multistage transform based on the image parameters. Image processing precision can be increased by fitting output to input data scopes between two or more stages. The image parameters of the parameterized encoding can define ranges, offsets, and bit depths of image components of the image, and the color profile can be a bit-depth independent color profile.

  • Patent number: 7429986
    Abstract: In one embodiment according to the present invention, relative z-ordering of segments in a digital image is determined. A method comprises forward and backward motion matching of image regions to determine overlap, followed by the creation of relationships (e.g., pairwise relationships) between regions and comparing the result with the original image to determine the relative z-ordering.

  • Patent number: 7425956
    Abstract: One embodiment of the present invention sets forth a method for implementing occlusion testing prior to processing a primitive command. The method includes the steps of determining that an occlusion test should be performed on an enclosed primitive, saving the primitive command on a deferred list, and disabling a rendering functionality in hardware. The method also includes the step of performing an occlusion query on the enclosed primitive where a pixel count is generated that indicates how many pixels within a bounding volume defined around the enclosed primitive are visible. One advantage of this method is that it provides occlusion testing functionality for graphics applications that do not use the occlusion testing functionality provided by graphics APIs. Implementing occlusion testing functionality in this fashion reduces rendering time, thereby increasing rendering performance.

  • Patent number: 7408545
    Abstract: With an image-based rendering (IBR) system based on linear interpolated concentric mosaics, an observer is able to wander through a real or synthesized scene and have new view images (optionally including stereo images) of the scene rendered as the observer moves. According to one embodiment, multiple viewing rays are extended in a viewing direction from the image to be rendered at a view point. For viewing rays that do not coincide with captured images, an image is generate based on the captured images. The image is generated by interpolating between at least two captured images based on a constant distance to objects in the scene. The view images that are displayed can be mono or stereo (e.g., simulating a pair of eyes of the observer).

  • Patent number: 7397482
    Abstract: A string display system for displaying display target strings includes a storage unit 50 that correlates and stores detection target strings and display numbers, a display time determination unit 56 that provisionally determines display times of the display target strings, and a detection unit 52 that detects the detection target strings included in the display target strings. The display time determination unit 56 conducts processing where, when the detection target strings are detected, the display numbers of the detection target strings are read from the storage unit 50, and the display times of the display target strings are shortened in accordance with the read display numbers. The string display system further includes a display unit 58 that displays the display target strings over the shortened display times of the display target strings.

  • Patent number: 7385603
    Abstract: A method for simulating motion of cloth or other flexible membranes corrects surface-to-surface intersection involving a membrane. The method may be applied at time intervals of a conventional motion simulation for computer-generated animation. When a collision is detected, a function for a line of intersection between intersecting surfaces is parameterized in terms of vertices of the membrane model. The function is differentiated, and a correction factor is applied to the dynamic simulation in proportion to the value of the partial derivative for respected ones of the intersected vertices. The correction factor may be smoothed over a number of vertices in the vicinity of the intersected vertices.

  • Patent number: 7336279
    Abstract: The present invention provides a time-series data display method and system for displaying time-series data items so that a user can grasp time more intuitively. First data associated with a desired date is retrieved and displayed, second data associated with a contiguous date is retrieved, and a display screen for the second data is displayed smaller than that for the first data in a temporal direction starting with the desired date. Third data is associated with a date contiguous to the second date retrieved, and is displayed inside the second data with a smaller display area. Also, in a hierarchical data display method and browser system, a display area is divided into an area where icons representing data items belonging to one level are displayed, and an area where child levels are displayed. As hierarchical depth increases, the data icons are made smaller and simpler. The hierarchical structure of a file system or data base can be displayed as a Venn diagram.

  • Patent number: 7336280
    Abstract: Described is a method and system in which storyboard objects coordinate the animation of multiple elements and/or media displayed on a computer graphics display. Storyboards relate properties of elements in an element tree to a timeline, such that the properties associated with a storyboard are animated/play together as a group by starting, stopping, seeking or pausing the storyboard. Triggers, such as controlled by user interaction with the displayed information, including property triggers that change values in response to a state change, and event triggers that fire events, may cause the storyboard to start, stop, pause and seek. Storyboards may be used in XAML-based programs, and may be directly associated with elements, or indirectly associated with elements via styles. Complex properties and changeables are supported. Media playback may be controlled via storyboards, and thereby coordinated with other media playback and/or animations.

  • Patent number: 7319469
    Abstract: A video apparatus consistent with certain embodiments has a receiver that receives a data stream containing video data and video overlay data, wherein the video data includes a censored region having boundaries. A video plane receives the video data in order to render a video frame for display, the video data including the censored region. A video overlay plane receives the video overlay data in order to render a frame of overlay video data for display. The overlay data has boundaries that overlay the censored region. An alpha plane defines overlay boundaries for the overlay data to determine how much of the overlay video data overlays the censored region when rendering the video frame. The alpha plane defines boundaries that are smaller than the boundaries of the overlay data and larger than the boundaries of the censored region. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
