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.
