First Claim
1. A recoding medium storing thereon a computer program, which when executed by a processor, causes the processor to perform operations including:
- setting an exposure time of an image sensor of a terminal of a customer so that, in an image obtained by capturing a subject that is installed in a store by the image sensor, a bright line corresponding to each of a plurality of exposure lines included in the image sensor appears according to a change in luminance of the subject;
obtaining a bright line image including a plurality of bright lines, by capturing the subject that changes in luminance by the image sensor with the set exposure time;
obtaining identification information of the subject, by demodulating data specified by a pattern of the plurality of bright lines included in the obtained bright line image;
sending the identification information to a server;
obtaining a menu listing a product of the store from the server;
displaying the menu on a display of the terminal; and
sending product information of the product that is selected by the customer when the product is selected by the customer.

Abstract
A method includes setting an exposure time of an image sensor of a terminal of a customer so that, in an image obtained by capturing a subject, a bright line corresponding to each of a plurality of exposure lines included in the image sensor appears according to a change in luminance of the subject. The method also includes obtaining a bright line image including a plurality of bright lines, by capturing the subject that changes in luminance by the image sensor with the set exposure time, and obtaining identification information of the subject, by demodulating data specified by a pattern of the plurality of bright lines. The method further includes sending the identification information to a server, obtaining a menu listing a product of the store from the server, displaying the menu on a display of the terminal, and sending product information of the product selected by the customer.

4. A terminal, comprising:
-
a processor; and a memory storing thereon a computer program, which when executed by the processor, causes the processor to perform operations including setting an exposure time of an image sensor of the terminal of a customer so that, in an image obtained by capturing a subject that is installed in a store by the image sensor, a bright line corresponding to each of a plurality of exposure lines included in the image sensor appears according to a change in luminance of the subject; obtaining a bright line image including a plurality of bright lines, by capturing the subject that changes in luminance by the image sensor with the set exposure time; obtaining identification information of the subject, by demodulating data specified by a pattern of the plurality of bright lines included in the obtained bright line image; sending the identification information to a server; obtaining a menu listing a product of the store from the server; displaying the menu on a display of the terminal; and sending product information of the product that is selected by the customer when the product is selected by the customer.

5. A server, comprising:
-
a processor; and a memory storing thereon a computer program, which when executed by the processor, causes the processor to perform operations including receiving identification information that is sent from a first terminal of a customer, the identification information of a subject installed in a store being received by the first terminal via visible light communication with the subject; sending a notification indicating that the customer comes to the store to a second terminal of a clerk of the store when the identification information is received; sending a menu listing a product of the store to the first terminal when the identification information is received, the menu being to be displayed on a display of the first terminal; receiving a product information of the product when the product is selected by the customer, the product information being sent from the first terminal to the server. - View Dependent Claims (6, 7, 8)
