A security device and an information processing device capable of maintaining information useful for confirming a occurrence of a crime which include a switch that is provided so as to be operable with a hand that holds a housing, a light-emitting element that emits pulsed light in accordance with the operation of the switch, an imaging unit that performs imaging in an emission direction of the pulsed light and supplies image information, and a communication unit that transmits the image information to a communication network are provided. This structure allows a user to emit the pulsed light to an assailant, which prevents crimes and transmit to the communication network.

Illumination devices may be provided with one or more light sources that emit light of the same, similar, and/or different optical spectra within a wavelength range, for example, from the extreme ultraviolet (UV) to the far infrared (IR). One or more of the light sources may be selectively adjusted to control the overall mix of light projected onto a scene of interest. For example, one or more light sources may be used, and sometimes in conjunction with other optical elements, to provide illumination having a particular angular intensity distribution, color temperature, and/or other desired optical properties for a scene within a field of view (FOV) of the camera of a mobile device used for videography and/or photography. One or more illumination devices may also be used as flashlights and/or as sources of electrical power for recharging mobile devices. Related methods are provided.
