A system includes a camera module, a processor, and a display drive unit. The camera module includes a lens, a color filter array having an IR filter, an R filter, a G filter, and a B filter, and an image sensor. The number of IR filters is larger than that of G filters, and the number of G filters is larger than that of R filters or B filters. The processor includes a signal extraction unit that extracts an RGB image signal and an IR image signal from an electrical source image signal from the camera module, a lane pattern image data generating unit that generates image data, a pedestrian image data generating unit that generates pedestrian image data. The display drive unit implements image data generated by the lane pattern image data generating unit and the pedestrian image data generating unit through a display.
