US Patent 7747155 Zoom lens assembly

A zoom lens assembly for a miniature camera, such as those used in cellular telephones and other personal electronic devices, is disclosed. One or more lenses of the zoom lens assembly are moved in and/or out of the optical path of the zoom lens assembly to change the magnification of the lens. Since the magnification does not necessarily require movement of lenses along the optical path of the camera, the length of the zoom lens assembly, and consequently of the camera as well, is substantially reduced.
