Method and apparatus for controlling amount of light in visible light communication system

摘要

A method and an apparatus for controlling an amount of light in a visible light communication system are provided. In the visible light communication system, a terminal measures an amount of light for a light signal received from a sensor, determines whether the measured amount of light is less than a threshold value, increases an amount of light for a light source signal to transmit to the sensor when the measured amount of light is less than the threshold value, and transmits, to the sensor, a light source signal according to the increased amount of light.

1. A method of controlling an amount of light by a terminal in a visible light communication system, the method comprising:
receiving a light signal from a sensor; determining whether an amount of light for the light signal is less than a threshold value or determining whether the light signal is detected in a reception area smaller than a reference size; increasing an amount of light for a light source signal to transmit to the sensor when the amount of light for the light signal is less than the threshold value or the light signal is detected in the reception area smaller than the reference size; and transmitting, to the sensor, a light source signal according to the increased amount of light.
