Abstract:
An electrically activated lens filter (204) with an electro-optic portion (418) having a radially and circumferentially symmetric electric field gradient is disclosed. More particularly, embodiments of the lens filter (204) include an electro-optic portion (418) having one or more conductive plugs (512) arranged around a center region (514) such that an electric field within the electro-optic portion (418) varies from a maximum at an outer rim (408) to a minimum outside of the center region (514). The lens filter (204) may include a plurality of front electrodes (409) and rear electrodes (410) accessible in an axial direction for electrically activating front and rear transparent conductive layers (414, 416), respectively.
Abstract:
A folded optical system that comprises two prisms with refractive power and in which at least one surface of at least one of the prisms is not rotationally symmetric. The materials and surfaces of the prisms in the folded optical system may be selected to provide a low F -number (e.g.,
Abstract:
A folded camera that includes two light folding elements such as prisms and an independent lens system, located between the two prisms, which includes an aperture stop and a lens stack. The lens system may be moved on one or more axes independently of the prisms to provide autofocus and/or optical image stabilization for the camera. The shapes, materials, and arrangements of the refractive lens elements in the lens stack may be selected to capture high resolution, high quality images while providing a sufficiently long back focal length to accommodate the second prism.
Abstract:
A light source module includes an array of illumination elements and a light diffusing material. The light source module is configured to receive a control signal for adjusting diffusion of light emitted from the light source module and in response adjust the amount of diffusion of light emitted from the light source module. A light source module may include a segmented light diffusing material where each segment is associated with an illumination element. And individual segments may have light diffusing properties that are different than other segments of the light diffusing material. Some illumination elements may emit light of a different color spectrum than other illumination elements, and a light diffusing material may scatter the different colored light to illuminate a scene with combinations of light of different colors. A light source module may be embedded in a mobile computing device.
Abstract:
A mobile device lens assembly having an electrically activated lens component with an electro-optic portion is disclosed. More particularly, embodiments of the mobile device lens assembly include the electro-optic portion and an interlock feature to engage a second lens element. The second lens element may have an interlock surface, which when engaged or mated with the interlock feature of the electrically activated lens component, may maintain alignment of the lens components along an optical axis. Other embodiments are also described and claimed.
Abstract:
A compact optic design is disclosed in which an image capture device's cover glass (or other transparent material) is imbued with optic power and affixed directly to the device's housing. A lens barrel, in which one or more additional lens elements are mounted, may be aligned with the optical lens formed by the cover glass and an image sensor to provide a complete camera module.
