Abstract

An apparatus and method in which a light control signal comprising successive computer generated images are retrieved from a storage medium and played back in an image space with a point of view with respect to a frame of reference of the image space synchronized with a changing point of view of images acquired in an object space by an image acquisition device sensed in an object space changing in its point of view with respect to a frame of reference of the object space, the frame of reference of the image space corresponding to the frame of reference of the object space.
