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;
determining whether the subject is in the box; and
receiving the signal transmitted by the subject when it is determined that the subject is in the box,wherein in the receiving,image data is obtained by capturing the subject with an exposure time so that (i) exposure starts sequentially for a plurality of exposure lines each at a different time, (ii) each of the plurality of exposure lines partially overlaps in exposure time an adjacent one of the plurality of exposure lines, and (iii) a bright line pattern appears in the image data according to the changing luminance, the bright line pattern corresponding to the plurality of exposure lines,the signal is obtained by demodulating the bright line pattern, andthe bright line pattern is caused to appear in the image data by setting the 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, and displaying a captured image that includes a box. The method also includes determining whether the subject is in the box, and receiving the signal transmitted by the subject when it is determined that the subject is in the box. In in the receiving, image data is obtained by capturing the subject with an exposure time, the signal is obtained by demodulating a bright line pattern, and the bright line pattern is caused to appear in the image data by setting the exposure time to be less than or equal to 1/480 second.
