Zoom related methods and apparatus
First Claim
1. A method of operating an interactive system, the method comprising:
- displaying a scene on a first portion of a display;
detecting user input indicating a zoom mode of operation; and
in response to the detected user input indicating the zoom operation, simulating viewing of a portion of said scene through binoculars, said simulating viewing of the portion of the scene through binoculars including using a second portion of said display to display a zoomed version of said portion of said scene while a third portion of said display is blocked from displaying a portion of said scene, said second portion of the display being smaller than said first portion of the display, said second and third portions being different portions of said first portion of the display.

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.
