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.

Abstract: A recoding medium storing a computer program, which, when executed by a processor, cause the processor to perform operations including: determining a pattern of a change in luminance, by modulating the signal to be transmitted; and transmitting the signal, by at least one light emitter changing in luminance according to the determined pattern of the change in luminance. The signal has a plurality of blocks, each block of the plurality of blocks includes (i) address information that indicates a position of a data segment in the signal and (ii) the data segment. In the transmitting, the signal is transmitted repeatedly at different times. The address information is used to identify a same location of the block data segment in the signal transmitted at a first time and in the signal transmitted at a second time, which is different from the first time. The signal has a check signal.

Abstract: A method includes capturing images with an image sensor while switching the shutter speed of the image sensor between a first speed and a second, higher speed. When a captured subject is a barcode, a barcode image is obtained when the shutter speed is the first speed, and barcode information is obtained by decoding the barcode in the image. When a captured subject is a light source, a bright line image including bright lines corresponding to a plurality of exposure lines included in the image sensor is obtained when the shutter speed is the second speed, and a visible light signal is obtained as visible light information by decoding a pattern of the bright lines in the obtained bright line image. The method also includes displaying an image obtained through capturing performed when the shutter speed is the first speed.
