Abstract

A data input device which inputs data to a navigation device includes: an image input unit capturing an image displayed on an image display carrier for displaying an image; a code extraction unit extracting a code hidden in the image; and a transmission unit transmitting the code to the navigation device.

Claims

1. A data input device which inputs data to a navigation device, comprising:

an image input unit capturing an image displayed on an image display carrier for displaying an image;

a code extraction unit extracting a code hidden in the image;

an ID inquiry unit transmitting the extracted code to an ID management server, and receiving a position data corresponding to the code; and

a transmission unit transmitting the received position data to the navigation device, wherein

the data input device holds a previously transmitted code and position data corresponding to the code as history information, checks whether or not the code is stored in the history information when the extracted code is transmitted to the ID management server, transmits the position data corresponding to the code to the navigation device if the code is stored, and transmits the code to the ID management server if the code is not stored.

2. The data input device according to claim 1, wherein:

the ID inquiry unit further receives a URL of a contents server corresponding to the code;

a contents information read unit accessing the contents server of the URL and receiving contents information from the contents server is further comprised; and

the transmission unit transmits the contents information to the navigation device.

3. A data input system, comprising:

the data input device according to claim 1; and

an ID management server storing the position data corresponding to the code, receiving the code from the transmission device of the data input device, and transmitting the position data corresponding to the code to the data input device.

4. A data input system, comprising:

the data input device according to claim 2; and

an ID management server storing the position data and the URL corresponding to the code, receiving the code from the transmission unit of the data input device, and transmitting the position data and the URL corresponding to the code to the data input device.

5. The data input system according to claim 4, wherein

the navigation device displays the contents information on a display unit of the navigation device.

6. The data input device according to claim 1, wherein

the code is hidden in an image by steganography.

7. The data input device according to claim 1, wherein

the image display carrier is a printed matter.

8. A printing device for printing an image captured by the image input unit of the data input device according to claim 7, comprising:

a code hiding unit hiding a code in an image;

a printing unit printing an image in which the code is hidden by the code hiding device; and

an ID management server associating and storing the hidden code and position data.

9. A printed matter printed by the printing device according to claim 8.

10. A data inputting method for a data input device, the method comprising:

extracting a code hidden in a image from among captured images;

transmitting the extracted code to a ID management server storing the extracted codes associated with a position data; and

transmitting to a navigation device the position data corresponding to the extracted code received from the ID management server, wherein

the data input device holds a previously transmitted code and position data corresponding to the code as history information

the transmitting checks whether or not the code is stored in the history information when the extracted code is transmitted to the ID management server, transmits the position data corresponding to the code to the navigation device if the code is stored, and transmits the code to the ID management server if the code is not stored.
