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: Embodiments of the present disclosure relate to power saving mechanisms for a wearable camera device. The camera device comprises an image sensor and lens assembly in an optical series with the image sensor. At a first orientation of the camera device, an offset is between a center axis of the image sensor and an optical axis of the lens assembly. At a second orientation of the camera device, at least one of the image sensor and the lens assembly sag due to gravity such that the center axis and the optical axis substantially overlap while the camera device is in a neutral state. The lens assembly and the image sensor can further allow a dynamic amount of sag relative to each other.

Abstract: A size of an optical aperture for an imaging system is adjustable. The size of the optical aperture can be adjusted based on refractive index matching, optical absorption, or near field coupling techniques. These techniques may also be used to provide a high speed optical shutter.
