| Abstract: | 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. |
