Abstract: Compact lens systems that may be used in small form factor cameras. The lens system may include a master lens with two or more lens elements arranged along an optical axis and having refractive power, and an optical actuator located on the object side of the master lens that may provide autofocus (AF) and/or optical image stabilization (OIS) functionality for the camera. An aperture stop for the camera may be included in the optical actuator, for example between a substrate and a flexible optical element of the optical actuator. Including the aperture stop in the optical actuator rather than in the lens stack may allow the optical actuator to be smaller in the X-Y dimensions (perpendicular to the optical (Z) axis) than it would be in a similar camera with the aperture stop located in the lens stack.

Abstract: An electronic device is provided. The electronic device includes a camera module having an optical axis and a set of one or more lenses centered along the optical axis. The electronic device also includes a display panel including an enhanced light transmission region. The enhanced light transmission region permits a greater amount of light to pass therethrough compared to at least one other region of the display panel. The electronic device further includes a display printed circuit board (PCB). In addition, the electronic device includes an aperture stop positioned between the set of one or more lenses and the display panel. The electronic device includes a transparent cover positioned over the display panel on an opposite side of the display panel from the display PCB. The electronic device also includes a housing configured to retain the camera module, the display panel, the display PCB, and the aperture stop therein.

Abstract: Various embodiments disclosed herein include zoom lens assemblies, as well as cameras and devices that incorporate these zoom lens assemblies. The zoom lens assemblies described herein include three lens groups, the first of which includes a light-folding element such as a prism. The second and third lens groups are moveable relative to the first lens group and relative to each other to change the focal length of the camera.

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: A camera may include an image sensor and an optics assembly that may include a light folding element and a lens group having one or more lenses. The light folding element may be placed optically between the image sensor and the lens group, and may redirect light passing through the lens group to the image sensor. The optics assembly may be stationarily attached to a stationary base of the camera, which may be further attached to a stationary housing of the camera. The image sensor may be moved, e.g., using an actuator, in multiple axes relative to the optics assembly to implement autofocus (AF) and/or optical image stabilization (OIS) functions.

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: 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 eye tracking system for detecting position and movements of a user's eyes in a head-mounted display (HMD). The eye tracking system may include at least one near-IR (NIR) eye tracking camera positioned at each side of the user's face and pointed towards eye-facing surfaces of eyepieces of the HMD, an illumination source that emits NIR light towards the user's eyes, and hot mirrors located between the eye-facing surfaces of the eyepieces and the user's eyes. The hot mirrors reflect at least a portion of NIR light, while allowing visible light to pass. The cameras capture images of the user's eyes reflected by the hot mirrors. Positioning the hot mirrors at or near the eye-facing surfaces of the eyepieces allows the cameras to be placed at the sides of the user's face without having to image through the eyepieces.
