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 light-emitting apparatus can shape infrared light. The light-emitting apparatus can include a reflective element including a reflective cavity configured to reflect infrared light incident thereon away from the infrared light-emitting diode, whereby the infrared light-emitting diode extends into the reflective cavity and is configured to emit infrared light into the reflective cavity. The light-emitting apparatus further includes a diffuser to receive infrared light directly from the infrared light-emitting diode and from the reflective element, whereby the diffuser is configured to shape the received infrared light.

摘要： Sidewall reflector structures disposed on the sidewalls of an LED or pcLED comprise a thin specular reflection layer and a light scattering layer disposed between the sidewall and the specular reflection layer. These sidewall reflector structures are more diffusively reflective than a specular reflector, yet maintain high reflectivity.
