Abstract: A method and an apparatus for demodulating visible light communication data modulated in a VPPM method are disclosed. According to an embodiment of the present invention, a method for demodulating visible light communication data comprises the steps of: generating sampling signals by receiving and sampling visible light communication signals modulated in a VPPM method; comparing a preset threshold with a first sampling signal among the sampling signals; setting an initial rise flag to a first level when the first sampling signal is larger than the preset threshold and setting the initial rise flag to a second level when the first sampling signal is smaller than the preset threshold; generating an accumulated sample value by accumulating the sampling signals increasing a sample count value; comparing the accumulated sample value with a value in which the threshold is multiplied by the sample count value; making a first bit data into demodulation data, if the initial rise flag is at the second level, when the accumulated sample value is larger than the value in which the threshold is multiplied by the sample count value; and making a second bit data into demodulation data, if the initial rise flag is at the first level, when the accumulated sample value is smaller than the value in which the threshold is multiplied by the sample count value.
