Information communication method for obtaining information specified by stripe pattern of bright lines

摘要

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.

1. An information communication method for 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; setting a longer exposure time than the exposure time; obtaining a normal captured image by capturing the subject and surroundings of the subject 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 plurality of bright lines 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 in which the subject and the surroundings of the subject are shown, in a form that enables identification of a spatial position of the part corresponding to the plurality of bright lines; and obtaining the information by demodulating data specified by a stripe pattern of the plurality of bright lines included in the obtained bright line image.
