A procedure with which a user sends an image recorded in the recording medium 177 of the electronic camera 10 to the photograph laboratory 92 via the cellular phone 40 to receive a print service will be hereinafter described.
The user inputs a power source of the cellular phone 40 and sets the cellular phone 40 in a state in which communication is possible via short distance wireless communication and the cellular phone telephone public line 44. Next, the user operates the mode switching dial 108 of the electronic camera 10 to set it in a communication mode and operates the power switch 106 to put the electronic camera 10 in an activated state.
The electronic camera 10 automatically starts wireless communication with the cellular phone 40 of a user existing in the vicinity and wireless communication is established between respective communication apparatuses. When the communication apparatuses enters a state in which they can carry out communication mutually, the information processing device 480 of the cellular phone 40 reads out the information of a telephone directory such as attribute information of dial-up recorded in the nonvolatile memory 482 and sends it to the electronic camera 10 via the transmitting and receiving device 457.
When the transmitting and receiving device 157 of the electronic camera 10 receives the information of a telephone directory, the information processing device 180 instructs the displaying device 168 to display the received information of a telephone directory.
FIG. 8 illustrates selection menus of dial-up connection destinations displayed on the displaying device of the electronic camera.
According to the figure, the displaying device 168 of the electronic camera 10 shows names of servers in destinations of communication such as Sato Photograph Laboratory and Image Sharing Service. A user can easily select a desired destination of communication by operating the increment button 111, the decrement button 112, the setting button 110 and the like.
When the user selects a desired destination of communication, a processing program of the electronic camera 10 activates software required for communication such as browser software, a protocol stack and a packet driver and starts connection with the access point 46 via the cellular phone 40 using information of a telephone directory such as a number or the like of a dial-up attribute received from the cellular phone 40.
When the electronic camera 10 and the access point 46 start communication directly via the cellular phone 40, a contract ID and a password of the user are sent to the access point 46, whereby connection to the Internet becomes possible.
In addition, instead of the electronic camera 10 receiving the information of a telephone directory for connecting to the Internet 48 from the cellular phone 40 to directly perform dial-up connection as described above, the cellular phone 40 may perform processing of dial-up connection.
In this case, when a user selects a desired destination of communication, the processing program of the electronic camera 10 activates software required for communication such as browser software, a protocol stack and a packet driver and sends information on a name of a server in the selected destination of communication to the cellular phone 40. Upon receiving the information on the server in the destination of communication, the cellular phone 40 reads out a telephone number for dial-up of a corresponding telephone directory and starts connection with the access point 46 via the cellular phone public line 44. When the connection is completed and communication is established, since the cellular phone 40 makes communication open to the electronic camera 10, it becomes possible for the electronic camera 10 and the access point 46 to carry out communication directly.
Further, the contract ID and the password for connecting the Internet 48 may be recorded in the nonvolatile memory 482 or the like of the cellular phone 40, read out when the cellular phone 40 is connected to the access point 46 and sent by the cellular phone 40 to establish communication or may be recorded in a nonvolatile memory of the electronic camera 10.
When communication is established as described above, the electronic camera 10 is connected to the Internet 48 and sends destination information, which is a server name of a destination of communication designated by the user in advance converted to a URL or a domain name, and address information and data of the electronic camera 10 in the origin of transmission on the Internet.
Then, the electronic camera 10 receives menu information from, for example, the photograph laboratory 92 in a destination of connection via the cellular phone 40 and the browser software of the electronic camera 10 displays a service menu shown in FIG. 9 on the displaying device 168. The user selects a desired service from the displayed service menu, browses images in accordance with Web menus or uploads images and voice information recorded in the electronic camera 10, whereby it becomes possible to easily receive various services such as upload and download.
Other embodiments of a communication terminal and a communication system will be hereinafter described.
In the above-described embodiment, a user selects a desired service menu after the electronic camera 10 and the Internet 48 are connected. On the other hand, if a user decides a service that the user receives in advance, a batch file in which information of the service to be received is written in advance is prepared as described below and connection with the Internet 48 is started.
FIG. 10 shows a directory structure of image files and print order files that are recorded in the recording medium 177 of the electronic camera 10 in advance.
As shown in the figure, a print order file “PRT-INFO.TXT” (a form of a batch file describing contents of processing) is stored in a directory “\Root\ORDER” of the recording medium 177 (recording device). In addition, various image files are recorded in a directory “\Root\IMAGE”.
FIG. 11 shows an example of a description of a print order file.
As shown in the figure, information such as a file name, the number of prints and a print type is written for each job in the print order file. When the electronic camera 10 receives a menu of destinations of communication for making communication connection to a communication apparatus on a network from the cellular phone 40, the information processing device 180 of the electronic camera 10 displays the menu information of the destination of communication on the displaying device 168. When the user designates a desired destination of communication via the inputting device 172, the information processing device 180 of the electronic camera 10 instructs the electronic camera 10 to connect communication with a communication apparatus on the above-described designated network.
Then, the electronic camera 10 reads out a print order file related to an apparatus on the network of the above-described designated destination of communication and an image file described in the print order file from the above-described recording medium 177 and, at the same time, sends them to a communication apparatus on the network.
In this way, since the electronic camera 10 is arranged to automatically send the print order file and the image file, which are prepared in advance, to the photograph laboratory 92 after dial-up connection is established, operation burdens for the user is reduced. Further, if an image or music information is downloaded, it becomes possible to send only a batch file to a predetermined server (communication apparatus) on a network to automatically download a desired image file, music information or the like.
In addition, as shown in FIG. 12, the attribute of a telephone directory recorded in the cellular phone 40 may be subdivided with the addition of an item for writing a service name, an item for writing a server type, an item for writing a communication protocol and the like. Thus, when the cellular phone 40 receives information of a print order service from the electronic camera 10, it automatically selects “xx photograph laboratory” as a destination of connection of “Print Service” to automatically upload the above-described print order file and image file.
In addition, when TCP/IP information such as an IP address and a DNS number is inputted in the cellular phone 40, if TCP/IP information set on a screen of a personal computer as shown in FIG. 13 is directly transmitted to the cellular phone 40 from the personal computer, it becomes possible to input accurate information without an error.
As described above, according to the communication terminal in accordance with the present invention, since the communication terminal is provided with a receiving device for receiving connection information such as a dial-up telephone number, attribute information, a URL, an IP address, gateway information and a DNS for making communication connection to a communication apparatus on a network and a transmitting and receiving device for sending and receiving information such as an image to and from the communication apparatus on the network based on the connection information received from the above-described cellular phone, it becomes possible to eliminate necessity of complicated setting inputs related to communication in the communication terminal in performing dial-up connection to the Internet or the like from the communication terminal.
In addition, according to the communication system in accordance with the present invention, since the communication system is composed of a cellular phone provided with a recording device which records connection information such as a dial-up telephone number, attribute information, a URL, an IP address, gateway information and a DNS for making communication connection to the communication apparatus on the network, a transmitting device which sends the above-described connection information to a communication terminal, a first receiving device which receives the information such as an image from the above-described communication terminal and a first transmitting and receiving device which sends and receives information to and from the communication apparatus on the above-described network and a communication terminal provided with a second receiving device which receives connection information for making communication connection to the communication apparatus on the network from the above-described cellular phone and a second transmitting and receiving device which sends and receives the information such as an image to and from the communication apparatus on the network based on the connection information received from the above-described cellular phone, it becomes possible to eliminate necessity of complicated setting inputs related to communication in the communication terminal in performing dial-up connection to the Internet or the like from the communication terminal.
