摘要： An information communication method obtains information from a subject using a terminal device that includes an image sensor. The method includes setting an exposure time of the image sensor having a plurality of exposure lines so that 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, and obtaining identification information of the subject. In the obtaining of the bright line image, 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. During asynchronous communication, a minimum width of the stripe pattern corresponds to at least two bright lines in the obtained bright line image.
