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 and obtaining second image data by image capture with a second exposure time, shorter than the first exposure time, in the visible light communication mode. When the second image data is obtained by capturing a plurality of subjects reflected on a reflection surface, the information is obtained by separating a bright line corresponding to each subject from bright lines included in the second image data according to a strength of the bright line and demodulating, for each subject, the data specified by the pattern of the bright line.
