Abstract: A camera includes an image sensor package, a lens assembly, and an adhesive or dam compound. The image sensor package includes an image pixel array and support circuitry disposed around the image pixel array. The lens assembly includes a lens barrel disposed around lens elements configured to focus image light to the image pixel array. The adhesive or dam compound adheres the lens barrel to the support circuitry in an inactive area of the image sensor package.

Abstract: A method for using cameras in an augmented reality headset is provided. The method includes receiving a signal from a sensor mounted on a headset worn by a user, the signal being indicative of a user intention for capturing an image. The method also includes identifying the user intention for capturing the image, based on a model to classify the signal from the sensor according to the user intention, selecting a first image capturing device in the headset based on a specification of the first image capturing device and the user intention for capturing the image, and capturing the image with the first image capturing device. An augmented reality headset, a memory storing instructions, and a processor to execute the instructions to cause the augmented reality headset as above are also provided.

Abstract: An electrically activated lens filter with an electro-optic portion having a radially and circumferentially symmetric electric field gradient is disclosed. More particularly, embodiments of the lens filter include an electro-optic portion having one or more conductive plugs arranged around a center region such that an electric field within the electro-optic portion varies from a maximum at an outer rim to a minimum outside of the center region. The lens filter may include a plurality of front electrodes and rear electrodes accessible in an axial direction for electrically activating front and rear transparent conductive layers, respectively.

Abstract: A portable electronic device has a device housing, and an electronic camera module in the device housing. The module has a focusing lens to focus light from a scene, an imaging sensor to receive the focused light, and an electro-optic variable aperture to allow different amounts of the light from the scene to reach the imaging sensor. The electro-optic variable aperture may include a first aperture stack placed on a transparent substrate and a second aperture stack placed on the first aperture stack. The first aperture stack defines a first aperture and the second aperture stack defines a second aperture that is larger than the first aperture. Each aperture stack includes a transparent conductive oxide layer that is common with the adjacent aperture stack. Alternatively the electro-optic variable aperture may include an aperture stack that has two transparent conductive oxide layer layers, where one layer is in the form of concentric annuli.
