An entertainment device comprises an input operable to receive a captured image from a video camera, a marker detector operable to detect a fiduciary marker within the captured image, and operable to estimate a distance and angle of the fiduciary marker, and a failure boundary calculation processor operable to calculate at least one of an additional distance and an additional angle from the currently estimated distance and angle of the fiduciary marker at which recognition of the fiduciary marker is assumed to fail. |
