Abstract: One embodiment of the present invention sets forth a technique for intelligently accessing one or more different hardware-based mechanisms for cropping out, blurring or blocking private content in a live preview image generated for the camera and in media recorded by the camera. The technique incudes receiving input regarding a plurality of objects to be concealed in media captured by an imaging device and identifying at least one of the plurality of objects in a field of view of the imaging device. Further, the technique includes modifying the at least one of the plurality of objects in a live preview image or media captured by the imaging device using one or more hardware-based actuators, where the modifying the at least one of the plurality of objects causes the one of the plurality of objects to be concealed.

Abstract: An integrated optical assembly with one or more integrated tunable lens elements within a lens barrel is described. The integrated optical assembly may be a part of an imaging device. The integrated optical assembly may include an optical element, a tunable lens element, and a lens barrel. The tunable lens element includes a tunable lens that is affixed to and communicatively coupled to a mount and is configured to adjust its optical power in accordance with an applied signal. The lens barrel is configured to hold the tunable lens element in optical series with at least one other optical element within the lens barrel. The lens barrel includes an integrated electrode that communicatively couples the mount to a controller which supplies the applied signal.
