Recording medium and control method thereof

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 (S). As a result, after it is determined the returned information contains authentication information, the printer notifies the DSC of its own authentication information (S).

Printing apparatus and control method thereof, and printing system

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.

Electronic apparatus, control method and computer readable medium for transmitting thumbnail data to an external apparatus

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. When the start of connection with the PC is instructed, the digital camera transitions into a state capable of wireless connection with the PC based on the set pairing information.

Image input device having different wireless communication states, control method and program therefor

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.

Digital information input apparatus

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.
