Abstract: A portable information terminal is provided. The portable information terminal includes a housing, a light-emitting region provided for a first surface of the housing, an imaging unit provided for said first surface of the housing, and a controller for supplying a control pulse signal and a shutter signal. The light-emitting region emits pulsed light in accordance with the control pulse signal. The imaging unit performs imaging in an emission direction of the pulsed light and supplies image information in accordance with the shutter signal.

Abstract: 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.

Abstract: To provide a novel security device. To provide a novel information processing device capable of maintaining information useful for confirming the occurrence of a crime. A structure including 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 is provided. With the use of a security device having the structure by a user, the pulsed light can be emitted to a thug or the like, which prevents crimes. Furthermore, information including an image of a crime scene can be transmitted to the communication network.
