INFORMATION COMMUNICATION DEVICE
First Claim
1. An information communication method, comprising:
- continuously capturing an image of a subject that transmits a signal by changing luminance, with an image sensor;
displaying a captured image that includes a box and a subject image for identifying the subject, while continuously updating a position of the subject image on the captured image, according to a positional relationship between the image sensor and the subject established when the image of the subject is captured;
determining whether the subject image is in the box; and
receiving the signal transmitted by the subject when it is determined that the subject image is in the box,wherein in the receiving,second image data is obtained by performing capturing with a second exposure time shorter than a first exposure time so that exposure starts sequentially for a plurality of exposure lines each at a different time and each of the plurality of exposure lines partially overlaps in exposure time an adjacent one of the plurality of exposure lines, and information is obtained by demodulating a bright line pattern that appears in the second image data and corresponds to the plurality of exposure lines, andthe bright line pattern is caused to appear in the second image data by setting the second exposure time to be less than or equal to 1/480 second.

Abstract
An information communication method is provided that includes continuously capturing an image of a subject that transmits a signal by changing luminance, with an image sensor. The method also includes displaying a captured image that includes a box and a subject image for identifying the subject, while continuously updating a position of the subject image on the captured image, according to a positional relationship between the image sensor and the subject established when the image of the subject is captured. The method further includes determining whether the subject image is in the box, and receiving the signal transmitted by the subject when it is determined that the subject image is in the box. In the receiving, information is obtained by demodulating a bright line pattern that appears in a second image data and corresponds to the plurality of exposure lines.

5. A non-transitory computer-readable recording medium storing an information communication program for performing information communication, the information communication program causing a computer to execute:
-
displaying a captured image that includes a box and a subject image for identifying the subject, while continuously updating a position of the subject image on the captured image, according to a positional relationship between the image sensor and the subject established when the image of the subject is captured; determining whether the subject image is in the box; and receiving the signal transmitted by the subject when it is determined that the subject image is in the box, wherein in the receiving, second image data is obtained by performing capturing with a second exposure time shorter than a first exposure time so that exposure starts sequentially for a plurality of exposure lines each at a different time and each of the plurality of exposure lines partially overlaps in exposure time an adjacent one of the plurality of exposure lines, and information is obtained by demodulating a bright line pattern that appears in the second image data and corresponds to the plurality of exposure lines, and the bright line pattern is caused to appear in the second image data by setting the second exposure time to be less than or equal to 1/480 second.
