VIDEO PROCESSING SYSTEM AND METHOD
First Claim
1. A method of introducing a graphical feature or effect into a part of one or more video images of a scene, the scene including a view of a plurality of objects disposed on an object plane, the part of the video images including one of the plurality of objects on the object plane, the method comprisingforming a three dimensional model view of the object plane,calculating a transform matrix for transforming points in the model of the object plane into the view of the object plane in the video image,forming the graphical feature or effect in the model of the object plane,transforming the graphical feature or effect from the model to the image view of the object plane using the transform matrix,identifying the one of the plurality of object which is to be viewed within the part of the video image, in which the object is present, andextracting the part of the image view from the video images, into which the graphical feature has been transformed, the extracted part including that part of the feature or effect, which has been transformed from the model.

Abstract
An image processing method introduces a graphical feature or effect into a part of one or more video images of a scene. The scene includes a view of a plurality of objects disposed on an object plane, the part of the video images including one of the plurality of objects on the object plane. The method includes forming a three dimensional model view of the object plane, calculating a transform matrix for transforming points in the model of the object plane into the view of the object plane in the video image, forming the graphical feature or effect in the model of the object plane, transforming the graphical feature or effect from the model to the image view of the object plane using the transform matrix, identifying the one of the plurality of object which is to be viewed within the part of the video image, in which the object is present, and extracting the part of the image view from the video images, into which the graphical feature has been transformed, the extracted part including that part of the feature of effect, which has been transformed from the model. The image processing method provides an improved way of adding a graphical feature or effect to a plane on which a plurality of objects are disposed, so that when a part of the video image, in which one of the plurality of objects, is viewed, the graphical feature or effect appears to the viewer to be a natural scene as if the graphical feature or effect is actually present.

8. An image processing apparatus operable to introduce a graphical feature or effect into a part of one or more video images of a scene, the scene including a view of a plurality of objects disposed on an object plane, the part of the video images including one of the plurality of objects on the object plane, the image processing apparatus including a data processor, which is operable
to form a three dimensional model view of the object plane, to calculate a transform matrix for transforming points in the model of the object plane into the view of the object plane in the video image, to form the graphical feature or effect in the model of the object plane, to transform the graphical feature or effect from the model to the image view of the object plane using the transform matrix, to identify the one of the plurality of object which is to be viewed within the part of the video image, in which the object is present, and to extract the part of the image view from the video images, into which the graphical feature has been transformed, the extracted part including that part of the feature or effect, which has been transformed from the model.

17. An apparatus for introducing a graphical feature or effect into a part of one or more video images of a scene, the scene including a view of a plurality of objects disposed on an object plane, the part of the video images including one of the plurality of objects on the object plane, the apparatus comprising
means for forming a three dimensional model view of the object plane, means for calculating a transform matrix for transforming points in the model of the object plane into the view of the object plane in the video image, means for forming the graphical feature or effect in the model of the object plane, means for transforming the graphical feature or effect from the model to the image view of the object plane using the transform matrix, means for identifying the one of the plurality of object which is to be viewed within the part of the video image, in which the object is present, and means for extracting the part of the image view from the video images, into which the graphical feature has been transformed, the extracted part including that part of the feature or effect, which has been transformed from the model.
