Abstract: An information communication method that obtains information from a subject includes setting an exposure time of an image sensor that, in an image obtained, a bright line corresponding to each of a plurality of exposure lines included in the image sensor appears, according to a change in luminance of the subject. A bright line image, in which the bright line is shown along with surroundings of the subject, is obtained by starting exposure of each of the exposure lines included in the image sensor at a sequentially different time. The bright line image is displayed and information is obtained when, in the bright line image, a part corresponding to the bright line is tapped, by demodulating data specified by a direction generally perpendicular to the exposure line in a pattern of the bright line corresponding to the tapped part.

Abstract: A visible light communication method transmits a signal by visible light communication. The visible light communication method includes modulating the signal into a predetermined blinking pattern, and transmitting the signal by causing visible light to blink according to the predetermined blinking pattern, from a projector disposed in an indoor space surrounded by a wall toward the wall. The visible light communication method also includes projecting video from the projector toward the wall, wherein the visible light is reflected by the wall to prevent the signal from being received in an outside of the indoor space, and the signal is used to transmit data related to the video projected to a plurality of terminals in the indoor space.
