Patent ID: 8767074

Claim:
A system for assisting visibility of a driver, the system comprising: a camera module including a lens configured to receive an optical signal of an image in front of a vehicle, a color filter array having IR filters, R filters, G filters, and B filters, and an image sensor configured to convert the received optical signal into an electrical source image signal for image processing, wherein a number of the IR filters is larger than a number of the G filters, and the number of the G filters is larger than a number of the R filters or the B filters; and a processor including a signal extraction unit configured to extract an RGB image signal and an IR image signal from the electrical source image signal output from the camera module, a lane pattern image data generating unit including an RGB interpolation part configured to interpolate the extracted RGB image signal, a signal expansion part configured to expand a data size of the interpolated RGB image signal, and a signal conversion part configured to convert the expanded RGB image signal into a YCbCr image signal, to generate data for a lane pattern display image, a pedestrian image data generating unit including an IR interpolation part configured to interpolate the extracted IR image signal, and a signal synthesizing part configured to synthesize the YCbCr image signal output from the signal conversion part to the interpolated IR image signal, to generate data for a pedestrian display image, and a display drive unit configured to implement image data generated by the lane pattern image data generating unit and the pedestrian image data generating unit through a display.
