    Abstract: Examples of the disclosure enable a mobile device to generate high quality images. In some examples, the mobile device includes a lens assembly that includes a first lens configured to provide positive optical power, and a telephoto stage including a second lens configured to provide negative optical power, and a third lens configured to perform one or more of increasing a sharpness and decreasing a distortion of an image associated with light transmitted through the lens assembly. The lens assembly has a track length that is less than or equal to approximately 6.0 mm and a focal length that is greater than or equal to approximately 7.3 mm. Aspects enable a lens assembly to be used in a mobile device environment, such that a mobile device including and/or associated with the lens assembly is configured to take high quality images.

    Abstract: The description relates to capturing or sensing color images of scenes and information about the type of light (e.g., light source) that illuminated the scene. One example can include an image sensor manifest as an array of pixels. This example can also include a lens configured to focus an image from a scene on the array of pixels. The array of pixels can entail first pixels that are configured to sense the image and second pixels that are configured to capture information about lighting of the scene.

    Abstract: In a portable electronic device having a digital camera function, focusing of an image may be accomplished by moving a movable image sensor assembly relative to a lens assembly that is affixed in a housing. An image sensor drive, such as a voice coil motor to move the movable image sensor assembly, may be positioned between the movable image sensor assembly and the lens assembly concentric with the lens assembly.

    Abstract: Focus self-calibration for a digital camera may be performed by moving a lens assembly of the digital camera over its travel range, and detecting travel limits of the lens assembly based on audio signal generated by the lens assembly reaching ends of the travel range. Digital-to-analog converter values corresponding to the lens assembly at the ends of the travel range may be used to create a camera focus profile.

    Abstract: Technologies are provided for IR illumination through background lighting sources. Some examples are directed to an IR light source such as IR LEDs being interspersed with visible light sources (e.g., LEDs) in a light guide of a display. IR LED configuration and/or light extraction features of the light guide may be selected such that a desired IR illumination pattern (e.g., a more centralized or a more uniform pattern) can be achieved. In other examples, an activation (turning on/off) of the IR LEDs may be used to generate the desired IR illumination pattern. The IR LEDs may be driven by the same circuitry as the visible light LEDs or by dedicated drive circuitry. Furthermore, the IR LEDs may be activated in an interlaced form with the visible light LEDs (e.g., selected frames in a stream of frames) to provide the IR illumination while displaying content.
