An imaging method to take high-speed moving objects with wide dynamic range image has been developed. In order to expand dynamic range of the image, the method combines two images taken under different exposure conditions at the same time. To obtain the two different exposure condition images, incident light is divided to different light intensity by optical beam splitter, and then these divided light are converted to images by CCD devices. Using this method we product a high-speed wide dynamic range camera. With this camera and newly developed algorithms, we have constructed a printed character recognition system for moving electronic parts. Using this system, a recognition accuracy of 98.1% (2895 parts, moving speed is 50cm/sec and lighting condition is 1500lux-10000lux) is obtained, which indicates sufficient performance for practice application.
