Abstract
An information communication method that enables communication between various devices includes: setting an exposure time of an image sensor; obtaining a bright line image including a bright line, by capturing a subject that changes in luminance by the image sensor with the set exposure time; setting a longer exposure time than the exposure time; obtaining a normal captured image by image capture by the image sensor with the longer exposure time; generating a synthetic image by specifying, in the normal captured image, a part that corresponds to the bright line included in the bright line image and superimposing a signal object on the normal captured image, the signal object being an image indicating the part; displaying the synthetic image; and obtaining information by demodulating data specified by a pattern of the bright line included in the obtained bright line image.
