An information communication method for obtaining information from a subject includes transmitting position information indicating a position of an image sensor used to capture the subject, and receiving an ID list that is associated with the position indicated by the position information. The method also includes setting an exposure time of the image sensor so that a bright line corresponding to an exposure line included in the image sensor appears according to a change in luminance of the subject. The method further includes obtaining a bright line image including the bright line by capturing the subject that changes in luminance by the image sensor with the set exposure time, obtaining the information by demodulating data specified by a pattern of the bright line included in the obtained bright line image, and searching the ID list for identification information.
