Abstract
Methods and apparatus for implementing user controlled zoom operations during a stereoscopic, e.g., 3D, presentation are described. While viewing a 3D presentation of a scene environment, a user may switch to a zoom mode allowing the user to zoom in on a particular portion of the environment being displayed. In order to maintain the effect of being physically present at the event, and also to reduce the risk of making the user sick from sudden non-real world like changes in views of the environment, the user in response to initiating a zoom mode of operation is presented with a view which is the same or similar to that which might be expected as the result of looking through a pair of binoculars. In some embodiments the restriction in view is achieved by applying masks to enlarged version of left and right eye views to be displayed.
