Light amount adjusting apparatus and photographing apparatus including the same

A photographing apparatus comprising:

• a light amount adjusting apparatus comprising:
• a two-dimensional (2D) aperture assembly that adjusts an opening area of a via hole through which the 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 moving 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 movable 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;
• the photographing apparatus further comprising:
• an imaging device that converts the light transmitted through the light amount adjusting apparatus into an electric signal;
• and
• a controller that executes a photographing apparatus by controlling the imaging device and the light amount adjusting apparatus, and selectively performing a 3D photographing mode in which two images are obtained by opening sequentially the first opening and the second opening that are formed by the 3D aperture plate and a 2D photographing mode in which an image is obtained by using the via hole opened by the 3D aperture plate.
