<p>An automatic camera selection system selects among different video sources based on image analysis of the video signals from one or more available video sources. In controlling the selection of video sources, the system can combine several sources to make images using elements from those several sources. In addition, the system can instruct other elements of the system to act differently to aid in the collection of appropriate video signals. All actions of the system are controlled by the system software, with no operator intervention required. In a preferred embodiment, the video selection system records an auditorium type of presentation for display, via recording or transmission, to remote audiences. The system selects from a number of video cameras, including automatic tracking cameras that follow a person on the auditorium stage. In addition, the system instructs the tracking cameras to operate in different modes, so as to produce images suitable to be used alone or in combination with other images, such as a composite image of a presenter and visual aid, such as projected slide images.</p> |
