Abstract
An apparatus and method for transmitting graphical representations is disclosed. The present invention has an image generator ( ) that generates an image ( ) of a head ( ) with facial features, including an eye portion ( ) that correlates to an eye ( ) in the head ( ). The apparatus also has a non-updating tracker ( ) that searches for an eye target image of the eye ( ) in the head ( ). The eye portion ( ) correlating to the eye ( ) is positioned at the target image located by the non-updating tracker ( ). The apparatus also has an updating tracker ( ) that searches for an updated eye target image when the non-updating tracker ( ) is unable to locate the eye target image. The updating tracker ( ) also positions the eye portion ( ) at the updated eye target image and updates the updated eye target image with the eye portion ( ). The updating tracker further determines the location of the eye portion ( ). The apparatus also has an image differentiator ( ) coupled to the trackers for providing image differential signals ( ), including eye differential signals representing positional difference from the location of the eye portion ( ). The apparatus also has a display device ( ) that receives the image differential signals ( ), including the eye differential signals, and animates a model ( ) with the received image differential signals ( ).
