摘要
在介绍照相机景深公式的基础上,讨论了在什么情况下数码相机与传统135相机成像效果相同,推出了二者景深相同的条件,并给出了在远摄和近摄时二者的景深变换关系。
Based on introducing the depth equation of the camera, this paper discusses on that under water kind of conditions the imaging results of the digital camera and the traditional 135 camera are the same, and deduces the conditions of the same depth of he digital camera and the traditional 135 camera, and gives the transformation relation of the depth between the telephoto and the near photo.
