Abstract

A method and apparatus for an imaging capable mobile terminal for close-up imaging is presented. An imaging lens arrangement has a first focal length in one direction and a second focal length in a second direction where the second focal length is shorter than the first focal length using an optical component such as a close-up lens or close-up lens and reflector which shortens the focal length of the lens arrangement. The close-up lens is mounted in a fixed position in the mobile terminal case and a rotatable camera assembly rotates a main camera lens into position behind the close-up lens so that the focal point of an object to be imaged can only converge at a point for close-up imaging.
