First Claim
Patent Images
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 reservation information related to the identification information from the server, the reservation information related to a content displayed by the subject; and
displaying the reservation information on a display of the terminal device.
