In this paper state the authors their studies on the analysis of the the generating lines of mirror surfaces which give the reflected images in the form of Equi-Solid Angle Representation or Equi-Distance Projection to incident rays from a pin hole. They solved the differential equations of the generating lines of the mirror surfaces numerically in successive method and have got four curves of generating lines of the mirrors. The authors have an intention of making trial pin hole cameras with some of refecting mirrors whose generating lines are defined here.
