摘　　要：提出加速逃逸时间算法生成分形图象的算法—屏幕分割算法,根据逃逸时间算法生成分形图象的特点,将屏幕区域进行矩形分割,检测每个矩形区域内是否有受控点,若没有,用背景色填充,反之则利用逃逸时间算法绘制图象。利用屏幕分割法,图象生成速度明显提高。A new method of generating fractal Image based on escape time algorithm- Screen Partition Algorithm(SPA) is developed in this paper.Screen is partitioned into a lot of rectangles and in- control point is detected in every rectangle,the rectangle is fined with background color if there is no in- control point ,otherwise ,escape time algorithm is been applied.Time of rendering fractal Image can be decreased with SPA.

关 键 词：逃逸时间算法 分形图象 屏幕分割算法
