Abstract: An information communication method selects between a visible light communication mode in which information is obtained from a subject using an image sensor having a plurality of exposure lines and a normal imaging mode. The method includes obtaining first image data by image capture with a first exposure time in the normal imaging mode. When an image is presented that prompts a user of a terminal device including the image sensor to move the terminal device to enable the information to be obtained, second image data is obtained by image capture with a second exposure time, shorter than the first exposure time, in the visible light communication mode. The information is obtained by demodulating data specified by a direction in a pattern of a bright line appearing in the second image data and corresponding to the exposure lines that is substantially perpendicular to the exposure lines.

Abstract: An information communication method selects between a visible light communication mode in which information is obtained from a subject using an image sensor having a plurality of exposure lines and a normal imaging mode. The information communication method includes obtaining first image data by image capture with a first exposure time in the normal imaging mode by sequentially starting exposure of each of the exposure lines of the image sensor at different times. Second image data is obtained by image capture with a second exposure time in the visible light communication mode. The information is obtained by demodulating data specified by a direction in a pattern of a bright line corresponding to the exposure lines, the second exposure time being shorter than the first exposure time. The second image data is obtained by capturing light emitted from the subject and spread by an optical system.

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.
