A communication terminal may include a processing unit that includes information identifying another communication terminal as path information in data when the data is directly transmitted from its own communication terminal to the other communication terminal, and a transmitting unit that directly transmits the data in which the path information is included by the processing unit to the other communication terminal.

Communication terminal and communication system

When a shutter release operation is performed at an electronic still camera, an MPU records image data output from an image capturing element into a CF card. The MPU also stores the image data in a transfer buffer memory of an interface circuit. The image data stored in the transfer buffer memory are transferred to a transfer buffer memory provided at an interface circuit of a personal computer connected via an IEEE-1394 cable. The MPU of the personal computer reads out the image data having been taken into the personal computer from the transfer buffer memory and records them in a specific recording area in a recording device.

A data recording/reproducing device includes: a position detection unit that detects information (hereafter referred to as position information) indicating a position at which data are acquired and reproduced; a determining unit that determines which specific set of geographical information, among a plurality of sets of geographical information defined in advance, the position information detected by the position detection unit at the time of data acquisition and data reproduction corresponds to; a recording control unit that records the acquired data into a recording medium based upon determining results provided by the determining unit; a selection unit that selects reproduction-permitted data from the recording medium based upon the geographical information determined by the determining unit at the time of data reproduction; and a reproducing unit that outputs and reproduces at least one set of data among the reproduction-permitted data having been selected.

Data recording/reproducing device, data recording/reproducing program and data reproducing device that protect private data from reproduction by unauthorized persons

A data communication apparatus comprises a storage unit that stores network connection information required for establishing a connection via a network with an external device, a light emission element that emits light, a light emission control unit that converts the network connection information into an optical signal and emits the optical signal from the light emission element by controlling an operation of the light emission element based upon the network connection information stored in the storage unit, and a reception unit that receives data transmitted from the external device via the network.

Data communication apparatus, electronic camera, and data communication system

A data storage device includes: a reception unit that receives data transmitted from a transmission device via a network; a storage unit that stores the data which has been received and creates registration history data for the stored data; and a charge processing unit that identifies an access point which has been used by the transmission device when accessing the network based upon access history data created by an access management device which monitors access to the network and the registration history data, and performs charge processing for a user of the transmission device according to a result of identification.

Image data outputted from an image-capturing device 14 is divided to generate a plurality of image data files that are separately reproducible. Using divisional image data included in each of the plurality of image data files, the image data before division is restored. When a color image is to be divided on a pixel-by-pixel basis, data for red, data for green and data for blue are respectively included in the image data of each pixel. When a color image is to be divided on an RGB basis, an image data file for red, a image data file for green and a image data file for blue are created.
