Abstract:
1. A method comprising: displaying a first view of a scene; marking an object, displayed in the scene, with a marker; recording coordinates of the object in the first view of the scene; displaying a second view of the scene where the object is no longer visible, wherein the second view of the scene is subsequent to the first view of the scene; displaying a third view of the scene where the object is visible, wherein the third view of the scene is subsequent to the second view of the scene; remarking the displayed object with the marker in the third view; performing a correlation computation directly between the coordinates of the object in the first view of the scene and coordinates of the object in the third view of the scene to make a determination of a change in direction and/or distance relationships of the object in the third view of the scene relative to the first view of the scene; and using the distance and/or direction relationships to track the object in the first, second and third views that are screens-widths away from each other as the first view is panned to the second and third views.
