  • Patent number: 7075556
    Abstract: A telestrator system is disclosed that allows a broadcaster to annotate video during or after an event. For example, while televising a sporting event, an announcer (or other user) can use the present invention to draw over the video of the event to highlight one or more actions, features, etc. In one embodiment, when the announcer draws over the video, it appears that the announcer is drawing on the field or location of the event. Such an appearance can be performed by mapping the pixels location from the user's drawing to three dimensional locations at the event. Other embodiments include drawing on the video without obscuring persons and/or other specified objects, and/or smoothing the drawings in real time.
    Type: Grant

  • Patent number: 6909438
    Abstract: A system is disclosed for blending two image that makes use of a color map which indicates colors in a foreground can be mixed with the background and how much of each source to mix. One embodiment of the invention restricts the use of the color map to only pixels in the foreground that correspond to a graphic (or effect) in the background. Another embodiment makes use of a gray scale matte which stores blending values for each pixel in the foreground.

  • Patent number: 6597406
    Abstract: A three-dimensional model is created to represent an environment to be captured on video. A camera is fitted with pan, tilt and/or zoom sensors. An operator selects a location in the environment. The three-dimensional model is used to determine the three-dimensional coordinates of the location selected by the operator. Information from the pan, tilt and/or zoom sensors is used to transform the three-dimensional coordinates to a two-dimensional position in the video from the camera. Using the two-dimensional position of the video, a graphic is properly added to the video such that the graphic appears to be at the selected location in the environment.
