  • Patent number: 9203987
    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).

  • Patent number: 8810669
    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.
