<P>PROBLEM TO BE SOLVED: To provide an illumination light communication system for transmitting individual information of each of receivers from a single transmission source (the number of light sources may be one or more) to each of a plurality of the receivers. <P>SOLUTION: Transmission information 101 transmitted from a transmitter includes: an information signal 103 which is desired to convey; a control signal 102 for identifying a receiver to which the information signal is desired to be transmitted; and an ending signal 104 following the information signal. The transmitter transmits the control signal 102, the information signal 103 and the ending signal 104 in sequence. A plurality of the receivers to which an individual ID number is preliminarily assigned reads and regenerates the information signal 103 only when the control signal 102 transmitted from the transmitter coincides with the ID number. <P>COPYRIGHT: (C)2012,JPO&INPIT |
