Abstract

An information communication method is provided for obtaining information from a subject. The information communication method includes transmitting position information indicating a position of an image sensor used to capture the subject, and receiving an ID list that is associated with the position indicated by the position information. The information communication method also includes setting an exposure time of the image sensor so that in a bright line corresponding to an exposure line included in the image sensor appears according to a change in luminance of the subject. The information communication method further includes obtaining a bright line image including the bright line, obtaining information by demodulating data specified by a cycle length or frequency of a stripe pattern of the bright line included in the obtained bright line image, and searching the ID list for identification information that includes the obtained information.

Claims

1. An information communication method of obtaining information from a subject, the information communication method comprising:

transmitting position information indicating a position of an image sensor used to capture the subject;

receiving an ID list that is associated with the position indicated by the position information and includes a plurality of sets of identification information;

setting an exposure time of the 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;

obtaining the information by demodulating data specified by a cycle length or frequency of a stripe pattern of the bright line included in the obtained bright line image; and

searching the ID list for identification information that includes the obtained information.

2. An information communication device of obtaining information from a subject, the information communication device includes a processor, the processor executes instructions comprising:

transmitting position information indicating a position of an image sensor used to capture the subject;

receiving an ID list that is associated with the position indicated by the position information and includes a plurality of sets of identification information;

setting an exposure time of the 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;

obtaining the information by demodulating data specified by a cycle length or frequency of a stripe pattern of the bright line included in the obtained bright line image; and

searching the ID list for identification information that includes the obtained information.

3. A non-transitory computer-readable recording medium for use in a computer, the recording medium having recorded thereon a computer program for obtaining information from a subject and causing the computer to execute:

transmitting position information indicating a position of an image sensor used to capture the subject;

receiving an ID list that is associated with the position indicated by the position information and includes a plurality of sets of identification information;

setting an exposure time of the 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;

obtaining the information by demodulating data specified by a cycle length or frequency of a stripe pattern of the bright line included in the obtained bright line image; and

searching the ID list for identification information that includes the obtained information.
