Abstract
A receiving device includes: an event camera configured to detect a rising edge and a falling edge of luminance as events; and a controller configured to receive, through the event camera, an optical wireless communication signal transmitted from a transmitting device. In the optical wireless communication signal, data 0 is represented by a zeroth event set including one or more events, and data 1 is represented by a first event set including one or more events and being different from the zeroth event set. The controller is configured to recognize data represented by the optical wireless communication signal without referring to an interval between events.
Claims6
A receiving device comprising:
- an event camera configured to detect a rising edge and a falling edge of luminance as events;
- and
- a controller configured to receive, through the event camera, an optical wireless communication signal transmitted from a transmitting device, wherein
- in the optical wireless communication signal, data 0 is represented by a zeroth event set including one or more events,
- in the optical wireless communication signal, data 1 is represented by a first event set including one or more events and being different from the zeroth event set, and
- the controller is configured to recognize data represented by the optical wireless communication signal without referring to an interval between events.
A transmission device comprising:
- a controller configured to transmit an optical wireless communication signal, wherein
- a receiving device for receiving the optical wireless communication signal is provided with an event camera that detects a rising edge and a falling edge of luminance as events, and is configured to receive the optical wireless communication signal through the event camera,
- the controller is configured to:
- represent data 0 in the optical wireless communication signal by a zeroth event set including one or more events;
- and
- represent data 1 in the optical wireless communication signal by a first event set including one or more events and being different from the zeroth event set, and
- the receiving device is configured to recognize data represented by the optical wireless communication signal without referring to an interval between events.
An optical wireless communication system comprising:
- a transmitting device configured to transmit an optical wireless communication signal;
- and
- a receiving device configured to receive the optical wireless communication signal transmitted from the transmitting device, wherein
- the receiving device is provided with an event camera that detects a rising edge and a falling edge of luminance as events, and is configured to receive the optical wireless communication signal through the event camera,
- the transmitting device is configured to:
- represent data 0 in the optical wireless communication signal by a zeroth event set including one or more events;
- and
- represent data 1 in the optical wireless communication signal by a first event set including one or more events and being different from the zeroth event set, and
- the receiving device is configured to recognize data represented by the optical wireless communication signal without referring to an interval between events.
