摘　　要：本文在透镜成像模型基础上,推导出模糊函数σ与物距及透镜焦距的关系,利用Z-buffer提出一种摄像机景深的模拟算法,在Z方向分层算法中提出三维掩模的概念,提高了算法效率.The relationship between obscure function a and the distance from object to lens and focal length is provided by using the lens model. A new deep of field simulate algorithm of camare is proposed based on Z-buffer. The concept of 3D mask is used to split levels algorithm in Z-buffer so as to the algorithm effectively increased.
