Patent ID: 8447189

Claim:
A visible light wireless communication transmitter, comprising: a source code recognizing unit that receives a source bit stream and recognizes the source bit stream as source codes of a unit of a first number of bits; and a line coding unit that encodes each of the source codes into an encoding code of a unit of a second number of bits, the second number being larger than the first number, and wherein the encoding code has the same number of bits corresponding to 1 as the number of bits corresponding to 0, wherein the first number is 4 and the second number is 6, and wherein the line coding unit encodes each of the source codes “0000”, “0001”, “0010”, “0011”, “0100”, “0101”, “0110”, “0111”, “1000”, “1001”, “1010”, “1011”, “1100”, “1101”, “1110”, “1111” into any one of the encoding codes “001110”, “001101”, “010011”, “010110”, “010101”, “100011”, “100110”, “100101”, “011001”, “011010”, “011100”, “110001”, “110010”, “101001”, “101010”, “101100”.
