Abstract: This paper presents an image-based scan-line method for cartoon-style rendering for the purpose of simulating the style of artists．The method firstly abstracts contour，then processes color and finally combines the two results to operate cartoon-style render on input images which users get with digital camera．Furthermore，the method gives two algorithm of histogram-based parameter computation for edge detection and color processing based on scan-line which help to complete real-time rendering process automatically．Results show that the approach can render images to an artistic style which is suitable for cartoon animation and personalized photo．
