Abstract: PURPOSE: A method and an apparatus for regenerating a three-dimensional image from a two-dimensional image are provided to improve a noise removal effect compared with a linear filtering method by processing images through a non-linear filtering method according to a median value. CONSTITUTION: A recovery image generator(310) creates a three-dimensional recovery image through reverse projection using a pixel value corresponding to a median value among pixel values of images. The images are created by the two-dimensional projection of a target to be three-dimensionally recovered. A re-projection image generator(320) creates a two-dimensional re-projected image through the re-projection of the three-dimensional recovered image. A residual image forming part(330) constitutes a residual image according to the difference between the projected image and the two-dimensional re-projected image.

Abstract: A micro mirror of an electrostatic driving mode and a micro mirror array using the same are provided to obtain a maximum rotation angle although a predetermined voltage is supplied between a first address electrode and a reflector. A micro mirror(200) includes an insulation substrate(210), an address electrode(220a), an electric charge part(240a), and a reflector(250). The address electrode, a stop electrode(280a), and supporting parts(270a,270b) are formed on the insulation substrate. The insulation substrate supports the reflector in order to separate the address electrode from the address electrode and the electric charge part. The address electrode is formed on the insulation substrate, and is made of conductive material. The electric charge part is insulated with a first address electrode and a second address electrode by a first insulation layer and a second insulation layer. A discharge-preventing layer is formed on a surface of the electric charge part.
