Abstract

The night vision that notifies obstacles in front of the car to support driver`s vision at night driving has been developed. The conventional infrared ray night vision system is weak to noise and has low contrast. To overcome the problem of infrared ray night vision system, the researching of the night vision using digital camera image is in processing. In this paper, we propose an image enhancement algorithm for the night vision. The proposed algorithm consists of three methods, YCbCr color space conversion , noise reduction and saturation and contrast improvement.
