Abstract: An information communication method that enables communication between various devices 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 (SK11) ; 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 (SK12) ; and obtaining information by demodulating data specified by a pattern of the bright line included in the obtained bright line image (SK13), wherein in the obtaining of a bright line image (SK12), the bright line image is obtained by capturing light emitted from the subject and expanded by an optical system.

Abstract: An information communication method that enables communication between various devices includes: (SK71) determining a plurality of patterns of a change in luminance, by modulating a respective plurality of signals to be transmitted; and (SK72) transmitting, by each of a plurality of light emitters changing in luminance according to any one of the determined plurality of patterns of the change in luminance, a signal corresponding to the pattern, wherein in the transmitting (SK72), each of the plurality of light emitters changes in luminance at a different frequency so that light of one of two types of light different in luminance is output per a time unit predetermined for the light emitter and that the time unit predetermined for the light emitter is different from a time unit predetermined for an other one of the plurality of light emitters.
