摘要： A method according to embodiments of the invention includes creating a three-dimensional profile of a scene, calculating a relative amount of light for each portion of the scene based on the three-dimensional profile, and activating a light source to provide a first amount of light to a first portion of the scene, and a second amount of light to a second portion of the scene. The first amount and the second amount are different. The first amount and the second amount are determined by calculating a relative amount of light for each portion of the scene.

摘要： Multi-color flash with image post-processing that uses a camera device with a multi-color flash and implements post-processing to generate images is described. In one aspect, the multi-color flash with image post-processing may be implemented by a controller configured to control a camera and flashes of at least two different colors. The controller may be configured to cause the camera to acquire a first image of a scene while the scene is being illuminated with the first flash but not the second flash, then cause the camera to acquire a second image of the scene while the scene is being illuminated with the second flash but not the first flash, and generate a final image of the scene in post-processing based on a combination of the first image and the second image.

摘要： A LED lighting module is described that is realized as a printed circuit assembly. The LED lighting module has a carrier with a strip of dielectric material and conductive circuit tracks printed on the dielectric material. Bare LED dies are mounted in a linear formation on the carrier. The width of the LED die formation does not exceed 0.75 mm and the area of the emission face of an LED die does not exceed 0.0625 mm2. Drivers are mounted on the carrier and are connected to drive the LED dies.

摘要： LED arrays with diffusing elements are disclosed. In various embodiments, diffusing elements in the form of one or more structures of a diffuser material may be provided between an LED array and an optical element that collects light emitted by the array and directs the light to an optical far field. The optical element may image or approximately image the LED array. The diffusing elements at least partially blur patterning in the far field illumination that may otherwise arise from the optical element imaging the array. Each LED may be a wavelength-converting LED in that it may include a light emitter arrangement and a wavelength-converter structure.

摘要： A semiconductor light-emitting device has an emitter matrix with an arrangement of emitter cells interspersed with non-emitter cells. The emitter cell has a semiconductor emitter, and a non-emitter cell does not have a semiconductor emitter. A number of bond pads for connection to a power supply and a plurality of wirebonds are present. Each wirebond extends from a bond pad to the semiconductor emitter of an emitter cell. An imaging arrangement includes a light source for illuminating a scene. The light source has a pair of such semiconductor light-emitting devices. A method of manufacturing such a semiconductor light-emitting device is also described.

摘要： An illumination arrangement in a mobile device is provided that uses an artificial neural network (ANN) to correct an image of a scene. The mobile device has an illumination apparatus with an LED array that emits light to illuminate a scene. The LED array has LEDs, separated by borders, that are independently driven. A camera has a sensor to capture an image of the scene. The ANN has a training mode in which the ANN is trained using a set of images captured by the camera to generate parameters. The ANN is trained offline in a cloud network. A processor uses the trained ANN in an inference mode to correct the image.

摘要： First and second LED arrays can include respective first and second pluralities of light-emitting areas that are separated by respective first and second boundaries. The first and second boundaries can be arranged in slightly different patterns. At least one lens can collimate light from the first LED array to form first illumination, collimate light from the second LED array to form second illumination, and illuminate the scene with the first and second illuminations. The first boundaries can form first dark bands in the first illumination. The second boundaries can form second dark bands in the second illumination, which can be slightly offset from the first dark bands at the scene.
