INFORMATION COMMUNICATION METHOD
First 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 bright line corresponding to an exposure line included in the image sensor appears according to a change in luminance of the subject;
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; and
obtaining the information by demodulating data specified by a pattern of the bright line included in the obtained bright line image,wherein in the obtaining of a bright line image, the bright line image is obtained by capturing light emitted from the subject and expanded by an optical system.

Abstract
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; 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; and obtaining information by demodulating data specified by a pattern of the bright line included in the obtained bright line image, wherein in the obtaining of a bright line image, the bright line image is obtained by capturing light emitted from the subject and expanded by an optical system.

14. An information communication device that obtains information from a subject, the information communication device comprising:
-
an exposure time setting unit configured to set an exposure time of an image sensor so that, in an image obtained by capturing the 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; an image obtainment unit including the image sensor, and configured to obtain a bright line image including the bright line by capturing the subject that changes in luminance with the set exposure time; and an information obtainment unit configured to obtain the information by demodulating data specified by a pattern of the bright line included in the obtained bright line image, wherein the image obtainment unit is configured to obtain the bright line image by capturing light emitted from the subject and expanded by an optical system.
