Abstract: Recording indicators for devices with cameras that provide protection from tampering so that the recording indicators cannot be easily disabled or masked. Recording indicators that are external to the camera lens and that emit visible light in an encrypted pattern are described. The device may process captured frames to detect the encrypted pattern; if the encrypted pattern cannot be detected, recording is disabled. In addition, modular accessories are described that the user has to attach to the device to enable recording; the presence of the modular attachment indicates to persons in the environment that they may be being recorded.

Abstract: Light-absorbing flange lenses that may be used in the lens stacks of compact lens systems. In a light-absorbing flange lens, the effective area of the lens is composed of a transparent optical material, and at least a portion of the flange of the lens is composed of an optical material that absorbs at least a portion of the light that enters the flange. Using light-absorbing flange lenses may allow the lens barrel to be eliminated from the lens system, thus reducing the X-Y dimensions of the lens system when compared to conventional compact lens systems that include a lens stack enclosed in a lens barrel. In addition, using a light-absorbing material in the flanges of the light-absorbing flange lenses may reduce or eliminate optical aberrations such as lens flare, haze, and ghosting in images.

Abstract: An imaging system including a front aperture, two or more refractive lens elements mounted in a lens barrel, and a photosensor. One or more of the components of the imaging system (e.g., the aperture, lenses, lens groups, and/or photosensor) are tilted with respect to each other and/or with respect to a center (or mechanical) axis of the imaging system to compensate for effects including but not limited to keystone distortion, resolution non-uniformity, and gradient blur that result from tilt of an object in the field of view of the camera with respect to the center axis of the camera.

Abstract: Recording indicators for devices with cameras that provide protection from tampering so that the recording indicators cannot be easily disabled or masked. Recording indicators that are integrated in a device's camera and that emit visible light through the camera lens aperture are described. In addition, modular accessories are described that the user has to attach to the device to enable recording; the presence of the modular attachment indicates to persons in the environment that they may be being recorded.

Abstract: A device may include a light-folded projector that may include an infrared (IR) light emitter and a light folding element. The light folding element may receive IR light emitted from the IR light emitter and fold the IR light one or more times to guide the IR light passing through the light folding element to exit the device to an environment. The device may also include a detector that may detect and/or recognize an object in the environment using the IR light from the light-folded projector, and a front-facing camera to capture images of the environment in front of the device.

Abstract: Compact folded lens systems are described that may be used in small form factor cameras. Lens systems are described that may include five lens elements with refractive power, with a light folding element such as a prism, located between a first lens element on the object side of the lens system and a second lens element, that redirects the light refracted from the first lens element from a first axis onto a second axis on which the other lens elements and a photosensor are arranged. The lens systems may include an aperture stop located behind the front vertex of the lens system, for example at the first lens element, and an optional infrared filter, for example located between the last lens element and a photosensor.

Abstract: An optical system for a camera may include a lens group having a plurality of lenses, a prism, and an image sensor. The prism may be positioned, optically, between the plurality of lenses and the image sensor along the optical transmitting path of the light. The prism may include at least four surfaces, which may fold the light within the prism at least four times to guide the light from the plurality of lenses passing through the prism to the image sensor. The prism may include multiple prisms joined together using an optical cement. The prism may include one or more aperture masks inside the prism to reduce flare.

Abstract: A folded lens system that includes lenses with refractive power and two light folding elements such as prisms. A first lens on a first axis refracts light to a first folding element. The first folding element redirects the light from the first axis onto a second axis on which one or more lenses are arranged. The lenses on the second axis refract the light to a second folding element. The second folding element redirects the light onto a third axis on which a sensor is disposed. The lens system may include a front aperture. The sensor may be moved on the third axis to provide autofocusing, or alternatively the lens system may include one or more optical actuators that provide autofocusing. The lens system may have a low F-number (

Abstract: Compact lens systems are described that may be used in small form factor cameras. The lens systems may include seven lens elements with refractive power, and may provide low F-numbers with wide field of view while maintaining or improving imaging quality and package size when compared to other compact lens systems. The lens systems may, for example, provide a focal ratio of 1.85 or less, with full field of view of 75 degrees or more. The lens systems may conform to a criterion for compactness TTL/ImageH
