Abstract: Embodiments of the present disclosure relate to a camera device assembled to reduce an auto-focusing actuation power for the most typical use case. The camera device comprises an image sensor and a lens assembly in an optical series with the image sensor. During assembling of the camera device, the lens assembly is assembled within the camera device to have an optical axis parallel to gravity and positioned to have an offset along the optical axis relative to a support assembly. The offset is determined during assembling of the camera device such that, when the camera device is oriented with a rotated optical axis orthogonal to gravity, the lens assembly is positioned at a neutral position relative to the image sensor without activation applied to the lens assembly.

Abstract: An optical lens assembly with an electrically controlled, tunable optical lens with an attached aperture stop provides autofocus or similar functionalities in a camera with a wide field of view (FOV) (that is larger than 100 degrees in diagonal direction). The tunable optical lens is positioned between a first optical lens and a second optical lens in the optical lens assembly with the assembly including any number of negative or positive optical power lenses and/or other optical elements such as polarizers, quarter wave plates, optical filters, and similar ones. An optical profile of the tunable optical lens is modified through a voltage-controlled thin film piezo actuator based on a determined focus distance.

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.
