Abstract: An apparatus is provided that includes a light source, a memory storing a visible light signal, a control circuit configured to control change in luminance of the light source in accordance with the visible light signal, and a receiver configured to receive another visible light signal, which rewrites over the visible light signal, by a communication method that is different from a visible light communication. The control circuit determines whether the visible light signal is rewritten by the another visible light signal or not when the receiver receives the another visible light signal, and the visible light signal is rewritten by the another visible light signal when the control circuit determines the visible light signal is rewritten by the another visible light signal. The control circuit controls the change in luminance of the light source to transmit the another visible light signal.

Abstract: An information communication method is provided for transmitting a signal using a change in luminance. The method includes determining a pattern of the change in luminance by modulating the signal to be transmitted, and transmitting the signal by a light emitter changing in luminance according to the determined pattern, wherein the pattern of the change in luminance is a pattern in which one of two different luminance values occurs in each arbitrary position in a predetermined duration. In the determining, the pattern of the change in luminance is determined so that a luminance change position in the duration is different for each of different signals to be transmitted, the luminance change position being a position at which the luminance rises or a position at which the luminance falls.

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 terminal in the indoor space.
