Abstract: Scenes can be imaged under low-light conditions using flash photography. However, the flash can be irritating to individuals being photographed, especially when those individuals' eyes have adapted to the dark. Additionally, portions of images generated using a flash can appear washed-out or otherwise negatively affected by the flash. These issues can be addressed by using a flash at an invisible wavelength, e.g., an infrared and/or ultraviolet flash. At the same time a scene is being imaged, at the invisible wavelength of the invisible flash, the scene can also be imaged at visible wavelengths. This can include simultaneously using both a standard RGB camera and a modified visible-plus-invisible-wavelengths camera (e.g., an “IR-G-UV” camera). The visible and invisible image data can then be combined to generate an improved visible-light image of the scene, e.g., that approximates a visible light image of the scene, had the scene been illuminated during daytime light conditions.

Abstract: Example embodiments relate to devices for media handoff. An example device includes a first transceiver configured to transmit and receive signals to communicate with a second transceiver of a handoff device. The signals are indicative of an orientation and a position of the first transceiver relative to the second transceiver. The device also includes an inertial measurement unit configured to measure changes in angular orientation or position of the device. Additionally, the device includes a memory. The memory stores a first set of instructions. Further, the device includes a processor communicatively coupled to the first transceiver, the inertial measurement unit, and the memory. The processor is configured to execute the first of instructions to cause the handoff device to output a piece of media.
