Abstract
A communications device such as a portable videophone includes a video camera and monitor disposed on a frame. An object selector is operatively linked to the monitor for selecting an object in an image displayed on the monitor. An image tracker is operatively coupled to the object selector and the camera for retaining an image of the selected object encoded in a video signal from the camera during subsequent relative motion of the object and the camera.

13. A communications method comprising:
-
operating a video camera to generate a first video signal of a selected scene including a plurality of objects;
feeding said first video signal to a video monitor or screen to display said scene on said monitor or screen;
during the display of said scene on said monitor or screen, producing a control signal designating a selected one of said objects;
after the producing of said control signal, generating a second video signal of a changing scene including an encoded image of said selected one of said objects in a predetermined substantially fixed video frame location; and
automatically maintaining said encoded image of said selected one of said objects in said video frame location in said second video signal even during relative movement of said camera and said selected one of said objects. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A communications device comprising:
-
a video signal generator including a video camera;
a video monitor, said video signal generator being operatively linked to said monitor for displaying an image of a scene on said monitor;
means for attaching said video signal generator and said monitor to a person;
a wireless transmitter operatively connected to said video signal generator for transmitting a first video signal from said video signal generator to a remote location; and
