Abstract
A visible light communication device is a visible light communication device capable of communicating with an other communication device, and includes an image acquisition unit and an image processing unit. The image acquisition unit acquires a first image signal including an R component, a G component, and a B component, the first image signal being output based on a communication signal of a visible light communication. The image processing unit outputs a second image signal in which an influence of the R component of the first image signal is reduced during the visible light communication with the other communication device.
Claims16
A visible light communication device capable of communicating with an other communication device, the visible light communication device comprising:
- an image acquisition unit for acquiring a first image signal including an R component, a G component, and a B component, the first image signal being output based on a communication signal of the visible light communication;
- and
- an image processing unit for outputting a second image signal in which an influence of the R component of the first image signal is reduced during the visible light communication with the other communication device.
A visible light communication method using a device capable of performing visible light communication, comprising:
- acquiring a first image signal including an R component, a G component, and a B component, the first image signal being output based on a communication signal of the visible light communication;
- outputting a second image signal in which an influence of the R component of the first image signal is reduced during the visible light communication;
- and
- displaying the second image signal on a display unit or reading information of the communication signal from the second image signal.
A display device including a screen capable of displaying an image, the display device comprising, at least while the display device and an other communication device perform visible light communication:
- a first image area for displaying an image signal that includes at least one of a G component and a B component;
- and
- a second image area capable of displaying an image signal including only an R component.
A visible light communication device capable of communicating with an other communication device, the visible light communication device being configured to transmit or receive data by switching a backlight OFF or ON, the visible light communication device comprising:
- an image acquisition unit for acquiring a first image signal including an R component, a G component, and a B component, the first image signal being output based on a communication signal of the visible light communication;
- and
- an image processing unit for outputting a second image signal in which an influence of the R component of the first image signal is reduced during the visible light communication with the other communication device.
