Abstract:
An information communication method which enables communication using a variety of devices includes: a step (SK91) in which a light-exposure time for an image sensor is set such that a plurality of bright lines corresponding to a plurality of light-exposure lines included in the image sensor are generated, in accordance with the brightness change of an object, in an image obtained by using the image sensor to photograph the object; a step (SK92) in which a bright-line image including the plurality of bright lines is acquired by using the image sensor to photograph, for the set light-exposure time, the object having a changing brightness; and a step (SK93) in which information is acquired by demodulating data identified by patterns of the plurality of bright lines included in the acquired bright-line image. In step (SK92), for each of the plurality of light-exposure lines, light exposure is started at sequentially different times, and light exposure is started after a prescribed idling time has elapsed since the completion of light exposure for an adjacent light-exposure line adjacent to the current light-exposure line.

Abstract:
A visible light communication method includes: obtaining a first ID identifying an area in which a receiver is present (SB3001); obtaining a second ID by the receiver through visible light communication (SB3002); and obtaining information corresponding to a third ID which is a combination of the first ID and the second ID (SB3003). For example, in the obtaining of a first ID, the first ID may be obtained by referring to a table showing correspondence between the first ID and location information obtained by the receiver and indicating a location of the receiver.
