Abstract
An information communication method includes: setting an exposure time of an image sensor so that, in an image obtained by capturing a subject by the image sensor, a bright line corresponding to an exposure line included in the image sensor appears according to a change in luminance of the subject; capturing the subject that changes in luminance by the image sensor with the set exposure time, to obtain the image including the bright line; and obtaining information by demodulating data specified by a pattern of the bright line included in the obtained image.
