Abstract:
The visible light communication device includes a control circuit configured to repeat a transmission process of transmitting a communication signal through modulating an intensity of visible light to be emitted from a light source. The control circuit is configured to, in the transmission process, arbitrarily select a time slot for transmission from a plurality of time slots set within a predetermined time period allocated to the transmission process, and transmit the communication signal in the time slot for transmission.
