PURPOSE: A color visible light communication system without flicker is provided to perform a high speed communication by using a light source without flicker. CONSTITUTION: A light encoding unit in a transmitter (ds) makes a digital value correspond to an encoding matrix value. A light control unit in the transmitter generates 'a lighting pattern which corresponds to the encoding matrix value'. A light emitting unit in the transmitter emits light in different colors according to the light emitting pattern. A light receiving unit in a receiver (sm) senses light. A light receiving calculator in the receiver calculates a decoded matrix value from the light receiving quantity pattern of the receiver. A light decoding unit in the receiver makes the calculated decoded matrix value correspond to the digital value.
