Abstract:
1. A light amount adjusting apparatus comprising: a two-dimensional (2D) aperture assembly that adjusts an opening area of a via hole through which light is transmitted; a three-dimensional (3D) aperture plate that forms a first opening and a second opening by blocking a part of the via hole, or moves to outside of the via hole to open the via hole; a first shielding plate that is movable to open or close the first opening; and a second shielding plate that is movable so as to close the second opening when the first shielding plate opens the first opening and to open the second opening when the first shielding plate closes the first opening; wherein: the 3D aperture plate, the first shielding plate, and the second shielding plate are moveable to the outside of the via hole to not block the transmitted light through the via hole when a 2D image photographing is performed; and the first shielding plate and the second shielding plate are movable to the via hole to close alternatively the first opening or the second opening formed by the 3D aperture plate when a 3D image photographing is performed.
