Abstract:
An information communication method includes: setting an exposure time of an image sensor to less than or equal to 1/2000 second so that, in an image obtained by capturing a subject by the image sensor, a stripe bright line parallel to a plurality of exposure lines included in the image sensor appears according to a change in luminance of the subject; obtaining the image including the stripe bright line parallel to the plurality of exposure lines by, using the set exposure time, starting exposure sequentially for the plurality of exposure lines each at a different time; and obtaining information by demodulating data according to, in a pattern of the bright line included in the obtained image, a brightness change in a direction perpendicular to the plurality of exposure lines.
