Abstract: Various embodiments disclosed herein include adaptive light source modules that can provide adaptive illumination to a scene. The adaptive light source modules may comprise a housing, an emitter array, and a lens. The emitter array comprises a plurality of emitters. The lens may redirect light emitted from the emitter array through a transparent window of the housing. The housing may further include a prismatic surface that distorts light emitted from the emitter array and/or one or more non-transparent portions that limits light travelling therethrough. The adaptive light source module may optionally comprise a light sensor, and a portion of the lens may be configured to direct light toward the light sensor.

Abstract: A light source module includes an illumination element and an adjustable light diffusing material. The light source module is configured to receive or generate a control signal for adjusting diffusion of light emitted from the light source module and accordingly adjust an amount of diffusion of light emitted from the light source module. In some embodiments, an adjustable light diffusing material includes a polymer stabilized cholesteric texture (PSCT), a smectic phase liquid crystal, a polymer network liquid crystal (PNLC), or other suitable material. A controller for a light source module may determine a level of diffusion based on a level of inclusion of a wide-angle field of view of a wide-angle lens system or a telephoto field of view of a telephoto lens system in a composite camera field of view that includes a combination of the wide angle field of view and the telephoto field of view. Also, the controller may determine a level of diffusion based or an estimated distance to a scene in a camera field of view that is to be captured.

Abstract: A device which includes a display can provide adjustable light output, based in part on the color of the display screen output, to control the light output of the display screen. An illumination processor can adjustably control light output based on the colors of portions of the display screen. The light output can be adjusted to maintain the light output of the display screen across a range of colors of display screen light output. Controlling the light output of the display screen results in controlling the illuminance of a subject. The device can include a camera which captures an image of the subject and displays the image on a portion of the display screen, where the light output of a portion of the display screen can illuminate the subject such that the captured image has at least a certain level of image quality.

Abstract: Apparatus and methods are described, including an apparatus for testing a light beam emitted by a light source. The apparatus includes a transparent substrate, a first face of the substrate being shaped to define a plurality of optical deflectors. At least one optical detector is positioned to face a second face of the substrate that is not opposite the first face. Each one of the deflectors is configured to deflect a portion of the light beam toward the detector, when the light beam is passed through the first face of the substrate. Other applications are also described.

Abstract: A lighting module which provides adjustably controllable illumination of a camera field of view of a camera module includes an adjustable collimator which can be adjustably positioned such that the emitted light beam is adjustably directed to illuminate various regions of various camera fields of view. The collimator can be adjusted via an actuator which adjustably positions the collimator relative to static components of the lighting module, including the light emitter. The light beam can be directed to illuminate a selected limited region of a camera field of view, based on identification of a subject within the limited region. The light beam can be adjustably directed based on user interactions with a user interface, including adjusting the light beam according to user-commanded beam angle, intensity, and direction. The light beam can be adjustably directed to illuminate a region according to different fields of view of different camera modules.

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.
