Abstract
A method and apparatus for producing data in a virtual set memory representing a composite image. The composite image data is produced from a combination of data representing a virtual image and data representing a camera field of view image. The invention includes a plurality of cameras, each disposed for developing data representing a respective field of view and each having a still store frame buffer associated therewith for receiving and storing data representing virtual images. The still store frame buffers are configured for subsequent selective retrieval. The invention also includes a virtual image data source for generating data representing virtual images and for supplying such data to the still store frame buffers associated with each of the plurality of cameras. Finally, the invention includes at least one compositor for compositing data representing the field of view of a selected one of the plurality of cameras and data representing a virtual image retrieved from a still store frame buffer associated with the selected one of the plurality of cameras. The compositor produces data in the virtual set memory.
