A microarray LED flash, applied to a mobile phone for lighting an adjustable flashlight or projecting an image, comprises a LED array module, a mixing optical module and an optical module. The LED array module is configured in a shell of the mobile phone for generating a patterning light source. The mixing optical module and the optical module are detachably configured on an external surface of the shell to receive the patterning light source from the LED array module for lighting the flashlight or projecting the image respectively. A LED array chip could be used as the LED array module and combined with the outboard mixing optical module to generate a flashlight with adjustable color and light pattern. Furthermore, the invention can use the optical module to substitute for the mixing optical module for projecting an image from the patterning light source, therefore the mobile phone has a projection function.

Apparatus, systems and methods for windows integration with cover glass and for processing cover glass to provide windows for electronic devices are disclosed. Transparent windows such as a transparent camera window, a transparent illuminator window and/or a transparent display window can be integrated into the cover glass. The apparatus, systems and methods are especially suitable for cover glasses, or displays (e.g., LCD displays), assembled in small form factor electronic devices such as handheld electronic devices (e.g., mobile phones, media players, personal digital assistants, remote controls, etc.). The apparatus, systems and methods can also be used for cover glasses or displays for other relatively larger form factor electronic devices (e.g., portable computers, tablet computers, displays, monitors, televisions, etc.).

Introduced here are computer programs and associated computer-implemented techniques for determining reflectance of an image on a per-pixel basis. More specifically, a characterization module can initially acquire a first data set generated by a multi-channel light source and a second data set generated by a multi-channel image sensor. The first data set may specify the illuminance of each color channel of the multi-channel light source (which is configured to produce a flash), while the second data set may specify the response of each sensor channel of the multi-channel image sensor (which is configured to capture an image in conjunction with the flash). Thus, the characterization module may determine reflectance based on illuminance and sensor response. The characterization module may also be configured to determine illuminance based on reflectance and sensor response, or determine sensor response based on illuminance and reflectance.

Introduced here are light sources for flash photography configured to produce high-fidelity white light that is tunable over a broader range of correlated color temperatures (CCTs) than conventional flash technologies. The light source can include multiple independently controllable color channels representing illuminants (e.g., light-emitting diodes) of different colors with varying degrees of saturation. Operating collectively, the multiple color channels can produce a high spectral quality white light corresponding to different CCTs (e.g., warm white light having a red hue, cool white light having a blue hue). Operating independently, these same color channels can be pre-flashed in a variety of prescribed sequences to probe the spectral characteristics of a scene, thereby allowing for an enhanced, spectrally matched white flash as well as collecting per-pixel reflectivity data that can be later used in during post processing of the captured image.

A security camera and assembly include a camera lens assembly, a lens tilt locking mechanism, and a grab handle having LEDs mounted thereon. Embodiments include a lens tilt locking mechanism coupled to the camera lens assembly for setting a field of view (FOV) for a camera lens of the camera lens assembly. The grab handle is pivotally coupled to the camera lens assembly via a pivoting mechanism. The grab handle having LEDs mounted thereon pivots to provide independent control of illumination to the FOV without shifting the FOV. In a further embodiment, the grab handle may further include an antenna embedded therein.

The present embodiment relates to a light-emitting module comprising: a substrate; a light source which is arranged on the substrate and emits laser light; a holder arranged on the substrate; a diffuser lens arranged in the holder and over the light source; and a diffuser ring for supporting the diffuser lens, wherein the diffuser lens comprises a plurality of microlenses, and the holder comprises an opening formed above the diffuser lens and a stopping protrusion for inhibiting the diffuser lens from being separated through the opening.

The present disclosure relates to optical systems, vehicles, and methods that are configured to illuminate and image a wide field of view of an environment. An example optical system includes a camera having an optical axis and an outer lens element disposed along the optical axis. The optical system also includes a plurality of illumination modules, each of which includes at least one light-emitter device configured to emit light along a respective emission axis and a secondary optical element optically coupled to the at least one light-emitter device. The secondary optical element is configured to provide a light emission pattern having an azimuthal angle extent of at least 170 degrees so as to illuminate a portion of an environment of the optical system.

An image capturing device includes a base, a light sensing element, an image capturing lens, and multiple light sources. The light sensing element is disposed on the base. The image capturing lens is disposed above the light sensing element. The light sources are disposed on the base and arranged beside the image capturing lens. Each of the light sources emits a light beam. A chief ray direction of the light beam has a horizontal component and a vertical component. The horizontal component and the vertical component are both greater than zero.

A camera includes an image-capturing part, a plurality of lamp cups, and a plurality of lighting parts disposed in the lamp cups correspondingly. The lamp cup includes two reflection members oppositely disposed. One of the reflection members thereon defines a light source position and has a first reflecting surface. The other reflection member has a second reflecting surface toward the light source position, and a third reflecting surface, close to the second reflecting surface and toward the first reflecting surface. The first reflecting surface and the third reflecting surface form a light-out opening therebetween. Some light travels from the light source position to be reflected by the second reflecting surface and the first reflecting surface in order to emit out of the light-out opening. Some light travels from the light source position to be reflected by the third reflecting surface to emit out of the light-out opening.

Ring illuminated surgical cameras and scopes having a ring lens and a plurality of LEDs. The LEDs set behind an electronic imaging sensor (camera) and positioned radially about the longitudinal axis of the lens and/or scope.
