INFORMATION COMMUNICATION METHOD |
摘要 |
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 plurality of bright lines corresponding to a plurality of exposure lines included in the image sensor appear according to a change in luminance of the subject; obtaining a bright line image including the plurality of bright lines, by capturing the subject changing in luminance by the image sensor with the set exposure time; and obtaining information by demodulating data specified by a pattern of the plurality of bright lines included in the obtained bright line image, wherein exposure starts sequentially for the plurality of exposure lines each at a different time, and exposure of each of the plurality of exposure lines starts a predetermined blank time after exposure of its adjacent exposure line ends. |

1. An information communication method of obtaining information from a subject, the information communication method comprising:
setting a first 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 appear according to a change in luminance of the subject; obtaining a bright line image including the plurality of bright lines, by capturing the subject changing in luminance by the image sensor with the set first exposure time; and obtaining the information by demodulating data specified by a pattern of the plurality of bright lines included in the obtained bright line image, wherein in the obtaining of a bright line image, exposure starts sequentially for the plurality of exposure lines each at a different time, and exposure of each of the plurality of exposure lines starts after a predetermined blank time elapses from when exposure of an adjacent exposure line adjacent to the exposure line ends. |
