An information communication method includes: obtaining a first image by capturing a subject; detecting a range of the subject from the first image; determining, from among a plurality of exposure lines, predetermined exposure lines for capturing the range of the subject; setting an exposure time so that, in a second image obtained using the predetermined exposure lines, a bright line appears according to a change in luminance of the subject; obtaining the second image including the bright line, by capturing the subject that changes in luminance using the predetermined exposure lines with the set exposure time; and demodulating data specified by a pattern of the bright line included in the obtained second image.
