Abstract:
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.
