  • Patent number: 6271890
    Abstract: A chromokeying panel for use in conjunction with a chromakeying system includes a plurality of first and second location. Each of the first and the second locations has a color within the color of a color keying spectrum of the chromakeying system. In addition, each of the first and the second locations are arranged to define a coded pattern for a computation of a perspective of the chromakeying panel with respect to a camera independently in each video field produced by the camera. The coded pattern may include a plurality of straight lines that intersect to define vertices. The plurality of straight lines may be spaced apart from each other so that for a given vertex, a ratio of the distance of one of the lines extending from the given vertex to a first adjacent vertex, to the distance of another of the lines from the given vertex to a second adjacent vertex is unique.

  • Patent number: 6122013
    Abstract: A chromokeying system includes a store that contains a representation of a known coded chromokeying pattern. The system further includes a frame grabber that grabs a video image including at least a portion of the known coded chromokeying pattern and a foreground subject. A perspective transformation computation unit computes a perspective transformation by comparing the video image of the portion of the coded chromokeying pattern with the known chromokeying pattern. The system may further include a background generation unit that receives a background image and applies the perspective transformation to the background image to produce a transformed background. The portion of the coded chromokeying pattern in the video image can then be replaced by the transformed background to create a composite image.

  • Patent number: 5923365
    Abstract: A sports event video manipulating system for manipulating a representation of a sports event, the sports editor including a video field grabber operative to grab at least one video field including a video image A/D converter operative to digitize a grabbed video field, an object tracker operative to track an object through a plurality of successive video fields, an object highlighter receiving input from the object tracker and operative to highlight the tracked object on each of the plurality of successive video fields, a D/A image converter operative to convert output of the object highlighter into a video standard format, and a video display monitor.

  • Patent number: 5903317
    Abstract: A system (FIGS. 7 and 8) and method (FIG. 1) for video tranmission of active events, for example sports events, having in the background physical images in designated targets, wherein the physical images are electronically exchanged with preselected virtual images, so that objects or shadows actually blocking potions of the physical images will be seen by viewers as blocking the same portions of the virtual images, and the motion of players or a ball blocking the physical image will block corresponding regions of the exchanged virtual images, so that the exchange electronic image will remain in the background of the event, exactly as the original image.
