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 communication system, comprising:
a plurality of cameras that generate image data by capturing an image;
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, wherein each of the plurality of transmission devices transmits light including a visible light communication signal whose luminance is temporally modulated in accordance with 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.
2. The communication system according to claim 1 ,
wherein the information includes address information indicating the storage location at which the image data is stored.
3. The communication system according to claim 1 ,
wherein the information includes an encryption key used in encryption of communication for a terminal to access the storage location at which the image data is stored.
4. The communication system according to claim 1 ,
wherein the information includes an identifier of a base station for wireless communication for a terminal to access the storage location at which the image data is stored.
5. The communication system according to claim 1 ,
wherein the information includes position information indicating a position of a location at which the image was captured.
6. A control method for a communication system including a plurality of cameras, a server, and a plurality of transmission devices in one-to-one correspondence with the plurality of cameras, the control method comprising:
generating image data by the plurality of cameras capturing an image;
storing the image data generated by each of the plurality of cameras in the server; and
transmitting, by each of the plurality of transmission devices, light including a visible light communication signal whose luminance is temporally modulated in accordance with 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.
