Abstract:
1. A method of transmitting data in a transmitting apparatus using visible light communication, the method comprising: receiving a color index and a luminance index of the color; determining an LED that emits a color having a largest ratio from among ratios of the plurality of light emitting diodes (LEDs) for expressing a color associated with the color index and the luminance index; determining a pattern index of the LED that emits a color having the largest ratio according to the luminance index; determining pattern indexes of the remaining LEDs according to the ratios of the plurality of LEDs; generating a light source control signal according to the pattern index of the LED that emits a color having the largest ratio and the pattern indexes of the remaining LEDs; and; controlling an on/off time of a light source comprising a plurality of LEDs according to the light source control signal to transmit the data using the visible light communication.
