Abstract: Even when the user carries a different combination of mobile devices on different days, the system can flexibly respond to those situations and misplacement of a mobile device can be prevented. Each mobile device includes a communication unit for communicating with other mobile devices, a GPS receiver for acquiring current location information of the mobile device, a group registration unit, a function-restricting unit for restricting a predetermined function, and a control unit. In each mobile device, other mobile devices located within a predetermined range of the mobile device are registered in the group registration unit as a group. After the registration, the other mobile devices located within the predetermined range of the mobile device are periodically detected, and the function-restricting unit is operated when the combination of the detected other mobile devices and the combination of the other mobile devices registered in the group registration unit differ.

Abstract: A plurality of mobile devices interoperate without configuration operation. A mobile device system including a plurality of mobile devices is provided. Each mobile device is operable in one of an independent-operation mode in which the mobile device operates with priority over the other mobile devices and a dependent mode in which the mobile device operates dependently on another mobile device and includes a control unit having a start-up-order detection unit configured to detect the start-up order of the mobile device with respect to the other mobile devices. A first mobile device operates in the independent-operation mode when the start-up order of the first mobile device detected by the start-up-order detection unit is earlier than the start-up order of a second mobile device and operates in the dependent-operation mode when the start-up order is later than the start-up order of the second mobile device.

Abstract: In order to make it possible to reduce the noise which is generated in an imaging device 1 in an accurate manner, after the dark current noise has been eliminated from the signal from the imaging device 1 by a black level compensation section 2, noise reduction processing is performed by a noise reduction section 3 and elimination of shot noise is performed, and subsequently white balance compensation is performed by a white balance compensation section 4. When noise reduction processing is performed with this type of structure, it becomes possible to reduce the noise in an accurate manner, since the noise reduction is performed after the black level compensation and moreover before the white balance compensation.
