Abstract: A stabilization actuation assembly includes a lens barrel, a magnetic assembly, one or more stabilizing coils, an outer shell, and a piece of ferromagnetic material. The lens barrel is configured to carry a lens that is positioned along an optical axis. The magnetic assembly includes a plurality of magnets that produce a magnetic field. The one or more stabilizing coils are coupled to a printed circuit board below the plurality of magnets. The outer shell includes an aperture through which the lens barrel can actuate. The piece of ferromagnetic material is coupled to a surface of the outer shell and is positioned to augment the magnetic field. A current supplied to the one or more stabilizing coils interacts with the augmented magnetic field to cause the magnetic assembly together with the lens barrel to translate in a direction perpendicular to the optical axis.

Abstract: An adjustment image of a projected image is captured by a disparity image sensor. A first defocus factor in generated response to comparing the adjustment image with a reference image driven onto a display projector assembly the generated the projected image. A second defocus factor is generated in response to an alignment of a first intensity profile of the adjustment image and a second intensity profile of the adjustment image. A focusing lens of the display projector assembly is adjusted in response to at least one of the first defocus factor and the second defocus factor.

Abstract: A display assembly generates environmentally matched virtual content for an electronic display. The display assembly includes a display controller and a display. The display controller is configured to estimate environmental matching information for a target area within a local area based in part on light information received from a light sensor. The target area is a region for placement of a virtual object. The light information describes light values. The display controller generates display instructions for the target area based in part on a human vision model, the estimated environmental matching information, and rendering information associated with the virtual object. The display is configured to present the virtual object as part of artificial reality content in accordance with the display instructions. The color and brightness of the virtual object is environmentally matched to the portion of the local area surrounding the target area.

Abstract: Embodiments of the present disclosure relate to a camera device with optical image stabilization (OIS) having a range of motion that is asymmetric along two spatial dimensions. The camera device includes an image sensor, a lens assembly in an optical series with the image sensor, and an OIS assembly. The OIS assembly initiates a first motion of at least one of the image sensor and the lens assembly along a first direction parallel to a first axis, the first motion having a first range. The OIS assembly further initiates a second motion of at least one of the image sensor and the lens assembly along a second direction parallel to a second axis orthogonal to the first axis, the second motion having a second range different than the first range.

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: 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.
