Optical path adjusting device and photographing apparatus having the same

A photographing apparatus comprising:

• an optical path adjusting device comprising,
• a supporting plate having a hole through which light passes,
• a two-dimensional (2D) aperture disposed in the supporting plate so as to adjust an open area of the hole, and
• a three-dimensional (3D) aperture having a plurality of first blinds and a plurality of second blinds,
• wherein the plurality of first blinds are disposed to correspond to a first area of the hole so as to move to open or close the first area, and the plurality of second blinds are disposed to correspond to a second area of the hole so as to move to open or close the second area;
• an imaging device that converts light passed through the optical path adjusting device into an electrical signal;
• and
• a control unit that performs photographing by controlling the imaging device and the optical path adjusting device, and selects and performs one of a 2D photographing mode and a 3D photographing mode, wherein, in the 2D photographing mode, the control unit performs photographing by controlling the optical path adjusting device to open the plurality of first blinds and the plurality of second blinds of the 3D aperture and then to adjust an open area of the 2D aperture, and in the 3D photographing mode, the control unit obtains two images by controlling the optical path adjusting device to maximally open the 2D aperture and alternately open and close the plurality of first blinds and the plurality of second blinds.
