INFORMATION COMMUNICATION METHOD

摘要

An information communication method that enables communication between various devices includes: setting an exposure time of an image sensor so that, in an image obtained by capturing a subject by the image sensor, a bright line corresponding to an exposure line included in the image sensor appears according to a change in luminance of the subject (SK11) ; obtaining a bright line image including the bright line, by capturing the subject that changes in luminance by the image sensor with the set exposure time (SK12) ; and obtaining information by demodulating data specified by a pattern of the bright line included in the obtained bright line image (SK13), wherein in the obtaining of a bright line image (SK12), the bright line image is obtained by capturing light emitted from the subject and expanded by an optical system.
