A camera (10) captures a subject facial image. A unit (30) generates a tracking signal containing feature extraction data. In conjunction with a memory store (40), the unit (30) generates an output signal representing a substitute face having the features of the subject face. To generate the tracking signal, the facial area is detected (3103, 3107-8) initially and used in location of the mouth (3102, 3110-3114) and eyes (3104-6, 3115-3118). Only the H and S components are used for detecting the facial area; and only the S and V components for the mouth within the facial area. A face vector may be generated (50) using the tracking signals.

[ We claim:] [16.] An image processing apparatus comprising means for receiving a subject facial image signal, means for generating a feature extraction tracking signal, and means for processing said tracking signal to provide a processed output signal, said processing means comprising means for:generating an image signal representing a substitute face; andmodifying said substitute face image signal in real time according to the tracking signal to generate an output signal representing the substitute face with facial features of the subject face by converting the tracking signal to a facial characteristic signal representing positional characteristics of facial features, the facial characteristic signal being a vector signal wherein pixel change data in an update image memory is selected by comparison of current and previous characteristic signals.
