Communication system, terminal, control method, and recording medium
View Patent ↗A communication system includes: a plurality of cameras that generate image data by capturing images; a server that stores the image data generated by each of the plurality of cameras; and a plurality of transmission devices in one-to-one correspondence with the plurality of cameras. Each of the plurality of transmission devices transmits light including, as a visible light communication signal, information related to communication for accessing a storage location at which the image data generated by a corresponding one of the plurality of cameras is stored in the server.
1. A terminal, comprising:
a light communication device that receives a light signal transmitted from a first transmission device from among a plurality of transmission devices, the light signal being modulated by transmission data including access information for image data captured by a camera, the first transmission device and the camera being mounted on a vehicle; and
a wireless communication device that receives the image data based on the access information.
2. The terminal according to claim 1 , wherein
the access information indicates a location of the image data stored at a server.
3. The terminal according to claim 1 , wherein
the access information indicates an identifier of an access point connectable via the wireless communication device.
4. The terminal according to claim 1 , further comprising a user interface that provides a selection of one light signal from among light signals transmitted from the transmission devices.
5. A method performed by a terminal including a light communication device and a wireless communication device, the method comprising:
receiving, by the light communication device, a light signal transmitted from a first transmission device from among a plurality of transmission devices, the light signal being modulated by transmission data including access information for image data captured by a camera, the first transmission device and the camera being mounted on a vehicle; and
receiving, by the wireless communication device, the image data based on the access information.
6. The method according to claim 5 , wherein
the access information indicates a location of the image data stored at a server.
7. The method according to claim 5 , wherein
the access information indicates an identifier of an access point connectable via the wireless communication device.
8. The method according to claim 5 , wherein the terminal further includes a user interface that provides a selection of one light signal from among light signals transmitted from the transmission devices.
