| Abstract: | In order to realize automatic focus, Apply geometric optical object\|picture relation, a mathematic model between the displacement of camera lens ΔA and the distance E of the object which is taken a photo is established on the paper, and adopt the photoelectricity coupler, voltage maintenance circuit etc. and mechanical transmission parts, realize automatic focus. There is certain reference value in design and maintenance of the autofocus system. |
