Abstract:
An information communication method obtains 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 by capturing the subject that changes in luminance by the image sensor with the set exposure time, and obtaining identification information of the subject. An exposure time of each of the plurality of exposure lines partially overlaps with an exposure time of an adjacent one of the plurality of exposure lines, and the subject includes a first area and a second area.
