ABSTRACT:
A figure is disclosed having a head with a back projected image to animate the facial expression of the figure. The image is back projected onto the head's face by a wide angle lens inside the head having an extremely short focal length. The lens is adjustable for focusing and image registration purposes in vertical, horizontal and lateral directions with respect to the face by a lens adjustment system also inside the head. The image is brought inside the head to the lens by a coherent fiber optic bundle having a high resolution which transfers the image from a remote image source, such as a motion picture projector. Independent movement of the head in all directions with respect to other parts of the figure is provided by a motion device. The lens adjustment system and fiber optic bundle ensure that the image always remains in proper focus and registration on the face despite free and unrestricted movement of the head by the motion device.
