US Patent 9360671 Systems and methods for image zoom

A method is provided that includes operating a first camera to capture a first image stream and operating a second camera to capture a second image stream. The method further includes initially using the first image stream to display a first field of view in a live-view interface of a graphic display and, while displaying the first image stream in the live-view interface, receiving an input corresponding to a zoom command. The method further includes, in response to receiving the input: (a) switching from using the first image stream to display the first field of view in the live-view interface to using a combination of the first image stream and the second stream to display a transitional field of view of the environment in the live-view interface and (b) subsequently switching to using the second image stream to display the second field of view in the live-view interface.
