Information communication method
First Claim
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 server;
obtaining place information identified by the identification information from the server, the place information indicating a location of the subject; and
displaying a location of the terminal device on a map, on a display of the terminal device using the place information.

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 a bright line corresponding to each of the plurality of exposure lines 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 by demodulating data specified by a pattern of the plurality of bright lines included in the obtained bright line image. The method further includes sending the identification information to a server, obtaining place information indicating a location of the subject from the server, and displaying a location of the terminal device on a map.

12. 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 server; obtaining place information identified by the identification information from the server, the place information indicating a location of the subject; and displaying a location of the terminal device on a map, on a display of the terminal device using the place information.
