Abstract: A recording medium removable from a host device includes a wireless communication unit for performing wireless communication with an external device different from the host device. The recording medium includes an image transmission control unit which transmits image data to the external device via the wireless communication established by the wireless communication unit by using an image transmission protocol. The recording medium switches which of the image transmission control unit of the recording medium and an image transmission control unit of the host device is used to communicate with the external device via the wireless communication unit.

Abstract: An electronic apparatus, method, and computer-readable medium shorten the response time of an electronic apparatus such as an electronic camera capable of communicating with an information processing apparatus such as a computer, and improve the usability of the information processing apparatus when the information processing apparatus requests data stored in the storage medium of the electronic apparatus. The electronic apparatus, which has a main storage device and an auxiliary storage device, is connected to an external apparatus, and can transmit/receive data to/from the external apparatus. Data to be requested by the external apparatus is loaded in advance from the auxiliary storage device to the main storage device before the external apparatus requests the data after connection to the external apparatus is established.

Abstract: An image input device connects to a network, and achieves, when a user wants to connect to a particular communication counterpart by operating the image input device, reliable connection with the counterpart that the user wants to connect by smoothly avoiding connection with other communication counterparts. Meanwhile, if the user wants to connect to the image input device by operating an information processor, connection with a communication counterpart which has issued a connection request earliest is achieved without operation of the image input device. For example, a digital camera has a wireless communication function of wirelessly connecting to a PC (personal computer), which is an information processor. Pairing information for identifying a PC to be a communication counterpart is set in advance, by connecting to the PC via a USB cable.

Abstract: A wireless communication device is connected to an external device such as a personal computer. If an image capture device such as a digital camera is wirelessly connected to the external device, the wireless communication device behaves as the image capture device. If the image capture device is wirelessly connected to the external device, the wireless communication device relays information between the external device and the image capture device.

Abstract: This invention has as its object to allow an authentication process that avoids unnecessary information from being stored in a digital camera irrespective of whether or not a digital camera connected to the printer has a direct print function. To this end, in this invention, in an early stage of connection between a digital camera DSC and PD printer, the PD printer side requests an object which contains a keyword as authentication information of those which are stored and held by the DSC (S29). As a result, after it is determined the returned information contains authentication information, the printer notifies the DSC of its own authentication information (S33).

Abstract: If a request of handle information to identify data existing in a recording medium is made to a digital camera by a PC, the digital camera collects the data existing in the recording medium by accessing a file system, generates unique handle information independent of the file system on the basis of a file path of the file system, and transmits it to the PC. When the request accompanied by the handle information is received from the PC, the digital camera executes a file path restoring process to the handle information, thereby restoring the file path which depends on the file system in the digital camera, retrieves the requested file by using the obtained file path, and transmits the data to the PC. According to this arrangement, installation costs can be suppressed by making an identification information management table unnecessary even while identification information which is independent of a logical data management system is used.

Abstract: When there are very many images stored in a memory card, a time after a computer and a digital camera have been logically connected with each other until the computer and the camera answers a user becomes extremely long. When the digital camera caches the information of a file stored in a storage medium by accessing the storage medium in a reproduction mode, and when the digital camera and the computer are physically connected to each other and they are in a communication mode, information which the computer appears to request finally is generated and stored. After that, when the digital camera receives a data transfer request from the computer, the digital camera transmits stored information to the computer in a lump.

Abstract: An image pickup apparatus in which when a decision button is depressed, a transfer confirmation screen is displayed without recording a selection record, and, when a shortcut button is depressed, a selection record is recorded and the transfer confirmation screen is not displayed. When one of image data recorded in a storage medium is selected by an operation of a user, a reproduction module executes reproduction for display of the image data, and upon a user transfer instruction and acceptance of the instruction by a queue, a communication module transfers image data to an external apparatus. When one of other image data recorded in the storage medium is selected by a user operation in the course of a transfer process of the image data by the communication module, the reproduction module executed a reproduction process on the selected other image data.

Abstract: A personal digital assistant 1 composed of a main body 2 formed with an operation section 212; a cover body 3 which is freely attached and slides parallel to the operating section 212 from a position overlapped on the operation section side of the main body 2; and an energization spring 45 formed in the cover body 3 which applies force along a direction which maintains an opened state in an opened position where the cover body 3 has been made to slide from the main body 2. Accordingly, a sliding type personal digital assistant can be stabilized in a closed position and/or an opened position and prevent opening or closing in a midway through position.

Abstract: This invention completes an authentication procedure early when it is ready to directly communicate with a printer, and serves as a user interface device of a direct print system. To this end, when a digital camera DSC is ready to directly communicate with a printer, and receives from the printer an inquiry about objects stored and held by the camera, it assigns an object which contains a word serving as authentication information of those stored and held in the DSC to a first handler (S52), assigns other objects (image data and the like) to subsequent handlers (S53), and sends that assignment result to the printer (S54).
