Disclosed are a color-independent visual-MIMO communications system using color-space-based image processing and a method for operating the same. The color-independent visual-MIMO communications system includes a transmission device and a reception device. The transmission device includes: a color space modulation unit which modulates input data into color data by referring to a color space; a conversion unit which converts the demodulated color data into parallel data corresponding to the size of an LED array; a mapping unit which maps the converted parallel data to the LED array according to a mapping rule; and the LED array which emits visible light corresponding to the mapped parallel data. The reception device includes: an image sensor which senses the visible light received from the LED array of the transmission device; an image processing unit which discriminating colors, generated by each of multiple LED units constituting the LED array, from the sensed visible light; a de-mapping unit which de-maps colors of emitted light for each LED unit to serial color data; and a decoding unit which decodes the de-mapped serial data into data bits.
