First Claim
Patent Images
1. A visible light communication device comprising:
- a light source unit configured to emit light for visible light communication; and
a control circuit that generates an original signal of the light to be emitted by the light source unit,wherein the control circuit generates the original signal that includes a payload part, a Cyclic Redundancy Check (CRC) part, and a recognition part, the payload part including identification information identifying the visible light communication device, the CRC part being determined according to data indicated in the payload part, and the recognition part being arranged immediately subsequent to the CRC part.

11. A receiving device for visible light communication, the receiving device comprising:
-
a light receiver that receives light from a visible light communication device; and a control circuit that extracts an original signal of the light received by the light receiver, wherein the control circuit obtains a recognition part from the original signal, and obtains a CRC part arranged immediately prior to the obtained recognition part from the original signal as a signal for identifying the visible light communication device.
