Abstract

An information communication method is provided for obtaining information from a subject using a terminal device that includes an image sensor having a plurality of exposure lines. The method includes setting an exposure time of the image sensor so that, in an image obtained by capturing the subject by the image sensor, a bright line corresponding to each of the 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, and obtaining identification information of the subject. The method further includes sending the identification information to a first server, obtaining access information from the first server, sending the access information to a second server, and obtaining information from the second server.

Claims (28)

1. An information communication method for obtaining information from a subject using a terminal device that includes an image sensor having a plurality of exposure lines, the information communication method comprising:

setting an exposure time of the image sensor so that, in an image obtained by capturing the subject by the image sensor, a bright line corresponding to each of the 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 first server;

obtaining access information from the first server, the access information related to the identification information in the first server;

sending the access information to a second server; and

obtaining information from the second server, the information related to the access information in the second server.

2. The information communication method according to claim 1 ,

wherein the access information is URL of the second server.

3. The information communication method according to claim 2 ,

wherein the first server is different from the second server.

4. An information communication device for obtaining information from a subject, the information communication device including a processor and an image sensor having a plurality of exposure lines, the processor executes operations comprising:

setting an exposure time of the image sensor so that, in an image obtained by capturing the subject by the image sensor, a bright line corresponding to each of the 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 first server;

obtaining access information from the first server, the access information related to the identification information in the first server;

sending the access information to a second server; and

obtaining information from the second server, the information related to the access information in the second server.

5. A non-transitory recording medium that stores a program for controlling an information communication device for obtaining information from a subject, the information communication device including a processor and an image sensor having a plurality of exposure lines, the program executed by the processor causing the information communication device to execute:

setting an exposure time of the image sensor so that, in an image obtained by capturing the subject by the image sensor, a bright line corresponding to each of the 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 first server;

obtaining access information from the first server, the access information related to the identification information in the first server;

sending the access information to a second server; and

obtaining information from the second server, the information related to the access information in the second server.
