PROBLEM TO BE SOLVED: To provide a CCD camera device for a vehicle, which detects not only straight light but refracted light and can clearly recognize a yellow line in the lane of a road. SOLUTION: An ultraviolet filter receives the input of light applied to the video of the lane and detects an ultraviolet area. A convergence part converges the light of the ultraviolet area and a light dispersion part disperses the light of the ultraviolet area, which is converged, and outputs plural light beams dispersed through different routes. A CCD cell image-picks up the plural light beams inputted through the different routes. An addition part adds plural picked-up video signals inputted from the CCD cell through the different routes and outputs the video signal which can detect the yellow lane.
