What was the latest and greatest electronic technology in vehicles? NEC Electronics

America Inc., have developed an image recognition technology that detects lane markers in real time. This advance in technology is really of great help for everybody to avoid car collision and the like.
How is it possible? In order to recognize obstacles, white lane lines, pedestrians and other items, many hi- tech sensors were integrated in the car system. Different motor companies employ different types of detection system like using infrared laser radar, using a stereo camera and image recognition, using a CMOS sensor and a circuit to calculate distance, and maybe a lot more.What about the cost? I think developers of this technology have common crucial difficulty: cost! As long as they want to provide us the best goods in the world nothing can be a hindrance!
