Information providing system

1. An information providing system for receiving or acquiring information corresponding to an image in which a code is embedded by using a print medium on which the image including the code embedded therein is printed, comprising:

a code transmission unit that transmits an image acquired by reading the image that is printed on the print medium and in which the code is embedded, or the code extracted from the read and acquired image;

an information providing unit that receives the acquired image, or the code extracted from the read and acquired image, and transmits information corresponding to the image, or information used for acquiring the information corresponding to the image;

an image receiving/acquiring unit that receives the information corresponding to the image, or receives the information used for acquiring the information corresponding to the image and accordingly acquires the information corresponding to the image using the information that is used for the acquisition; and

an information changing unit that changes the information corresponding to the image in the information providing unit, wherein:

the code transmission unit transmits, together with the code, identification information uniquely identifying the code transmission unit; and

the information providing unit receives the code and the identification information, and, depending on the identification information, determines the information that the information receiving/acquiring unit receives or acquires.

2. The information providing system according to claim 1 , wherein:

the code transmission unit and the information receiving/acquiring unit are included in one terminal.

3. An information providing system for receiving or acquiring information corresponding to an image in which a code is embedded by using a print medium on which the image including the code embedded therein is printed, comprising:

a code transmission unit that transmits an image acquired by reading the image that is printed on the print medium and in which the code is embedded, or the code extracted from the read and acquired image;

an information providing unit that receives the acquired image, or the code extracted from the read and acquired image, and transmits information corresponding to the image, or information used for acquiring the information corresponding to the image;

an image receiving/acquiring unit that receives the information corresponding to the image, or receives the information used for acquiring the information corresponding to the image and accordingly acquires the information corresponding to the image using the information that is used for the acquisition; and

an information changing unit that changes the information corresponding to the image in the information providing unit, wherein:

the information changing unit transmits, to the information providing unit, the code extracted from the image acquired by reading the image that is printed on the print medium and in which the code is embedded, and the identification information uniquely identifying the information changing unit; and

the information providing unit receives the code and the identification information from the information changing unit, and determines whether or not information corresponding to the image specified by the information changing unit is to be changed by using the code and the identification information.

4. The information providing system according to claim 3 , wherein:

the information changing unit can rewrite the information corresponding to the image stored in the information providing unit.

5. The information providing system according to claim 3 , wherein:

the information changing unit can rewrite the information used for acquiring information corresponding to the image stored in the information providing unit.

6. The information providing system according to claim 3 , wherein:

the code transmission unit and the information receiving/acquiring unit are included in one terminal.
