Abstract: Electronic devices, methods, and program storage devices for achieving smooth zooming operations during video capture are disclosed. In particular, smooth zooming may be desirable during video capture operations that involve a single image capture device and/or transitioning between two or more distinct image capture devices, e.g., having different optical and/or zooming properties, during the video capture. When video zooming is done abruptly, it can lead to an unpleasant user experience. The techniques described herein to improve the smoothness of zooming operations include: the use of longer zoom “ramps” for image capture devices; the “early” transitioning between image capture devices during video capture; and the performance of additional “digital zoom smoothing-aware” video image stabilization operations. The embodiments described herein also provide for a more consistent user experience between video streaming (i.e., “preview”) modes and the recorded (i.e., “final”) zoomed video that is produced using the various zoom smoothing techniques described herein.
