Apparatus and method for, in an image space, decoding and playing back a light control signal having successive computer generated images in correspondence with a changing point of view acquired by a device navigated in motion in an object space

摘要

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.
