Claim:
1. An information communication method of obtaining information from a subject, the information communication method comprising: setting an exposure time of an image sensor so that, in an image obtained by capturing the subject by the image sensor, a plurality of bright lines corresponding to a plurality of exposure lines included in the image sensor appears according to a change in luminance of the subject; obtaining a bright line image including the plurality of bright lines, by capturing the subject that changes in luminance by the image sensor with the set exposure time; and obtaining the information by demodulating data specified by a striped pattern of the plurality of bright lines included in the obtained bright line image, wherein a value of a relative exposure time, which is obtained by dividing a luminance of a subject change period by the exposure time set in the setting, is smaller than or equal to 1.5, and wherein the exposure time set in the setting is longer than a period of a high frequency noise included in the luminance of the subject.
