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 computer-implemented method is provided, in which a plurality of luminance change frequencies of a light emitter is determined by coding one of a plurality of transmission information sources. The light emitter transmits a transmission information source by a change in luminance according to each of the plurality of luminance change frequencies. A signal, which controls the change in luminance of the light emitter according to each of the plurality of luminance change frequencies, is output to the light emitter. The plurality of luminance change frequencies include a first frequency and a second frequency. A signal of the first frequency and a signal of the second frequency respectively cause the light emitter to change in luminance according to the first frequency during a first time period and to change in luminance according to the second frequency during a second time period after the first time period has elapsed.
