Abstract:
A method for aligning among visible light communication devices comprises the following steps: generating a visible light signal and transmitting same to a corresponding device; determining whether the visible light signal that is output via the screen of the device is identifiable; correcting the color of the visible light signal that is output on the screen if the visible light signal is not identifiable; and using the visible light signal that is corrected to perform alignment for visible light communicating with the corresponding device.
