In this paper, we present a technique for applying artistic effects to videos based on a pencil rendering technique. First of all, we propose a vectorized line generation method as a primary technique for solving temporal coherence problem which appears when applying some artistic effects to video. In addition, we propose progressive pencil rendering technique which controls detailed range of drawings from rough sketch to detailed drawing for video. Also, regarding that a real color pencil has a limited set of colors, we suggest limited color pencil rendering method. Furthermore we analyze hand drawing pencil drawings, compare them with rendering results and complement some weakness. A series of our works has a meaning of not only technological but also aesthetical consideration for pencil drawings.
