Abstract: A mobile device system includes a plurality of mobile devices, each to which unique identification information is assigned, wherein each mobile device includes a location-information acquisition unit, a communication unit, and a group registration unit. The communication unit links location information acquired by the location-information acquisition unit of the mobile device and the identification information of the mobile device, sends the information to other mobile devices, and receives from the other mobile devices location information of the other mobile devices and identification information linked to the location information of the other mobile devices. The group registration unit detects other mobile devices located within a predetermined range of the mobile device on the basis of the location information of the other mobile devices and the location information of the mobile device and registers the identification information of the detected other mobile devices as a group.

Abstract: A plurality of mobile devices interoperate without configuration operation. A mobile device system including a plurality of mobile devices is provided.

Abstract: An imaging apparatus comprises an optical magnification changing mechanism which optically changes a magnification of an image, and an electronic magnification change mechanism which reduces or expands a magnification with respect to image data by signal processing. The optical magnification changing mechanism is configured so that a magnification is discrete and a focal position changes together with a focal distance. The electronic magnification change mechanism carries out an interpolation process such that the number of pixels is increased with respect to a predetermined region of read image data during an expanding process, and carried out a process for discretely sampling a wide region as compared with a readout region obtained by the sampling provided when no magnification conversion is made, during a reducing process, thereby offsetting a change of the focal position in the optical magnification changing mechanism.
