PROBLEM TO BE SOLVED: To easily obtain identification information of an illumination device even from a device that cannot perform visible light communication.SOLUTION: An imaging unit (camera) of an identification information acquisition device 100 consecutively images an illumination device 300 that is outputting, as a visible light signal, identification information for identifying its own device on a network (wired LAN 400) under the control of a control unit. Then, the identification information acquisition device 100 obtains identification information such as the MAC address of the illumination device 300 on the basis of each of captured images which are obtained by consecutive imaging.SELECTED DRAWING: Figure 1 |
