Abstract: In a base station device, a receiver receives a normal signal from one terminal device included in one of a plurality of groups each including a plurality of terminal devices. The transmitter transmits the normal signal received by the receiver to the rest of the terminal devices included in the group. When the receiver has received an emergency signal from one terminal device included in one group, the transmitter transmits the emergency signal that has been received by the receiver to the rest of the terminal devices included in the group and terminal devices other than those in the group.

Abstract: In a terminal device, a receiver receives a plurality of signals from a plurality of other terminal devices. When the receiver has received a plurality of emergency signals, a setting unit sets priorities for a plurality of other terminal devices that are the transmission sources for the plurality of emergency signals. A notification unit gives notification of information regarding the plurality of other terminal devices that have transmitted the emergency signals, based on the priorities that have been set by the setting unit.

Abstract: A reception unit in a terminal device receives an emergency signal from a further terminal device. A computing unit computes a distance between the host terminal device and the further terminal device. A comparison unit causes a camera connected to the terminal device to start video recording when the reception unit receives the emergency signal and the distance computed by the computing unit is equal to or smaller than a predetermined video recording start threshold value.

Abstract: Provided is an image pickup apparatus that includes: an image pickup unit configured to generate picked-up image data by an image pickup process; a camera shake detection unit configured to detect an angular velocity generated by camera shake when shooting; an electronic image stabilization unit configured to perform an image stabilization process by moving a position of a cropping area in the picked-up image data, based on the angular velocity detected by the camera shake detection unit; and an area changing unit configured to change a size of the cropping area with respect to the picked-up image data, based on the angular velocity detected by the camera shake detection unit.
