| 20080317459 | Electrical Aperture and Shutter Device having a transparence Switching Element - An electrical aperture and shutter device having a transparence switching element includes an operating element, a transparence switching element, and a controller. The operating element is configured for producing a signal. The transparence switching element is configured for controlling a transparence and a light-passing time of the transparence switching element and thereby carrying out the functions of aperture and shutter. The controller is configured for controlling an operation of the transparence switching element by receiving the signal produced by the operating element. A camera incorporated an electrical aperture and shutter device having a transparence switching element therein, also is provided. | 12-25-2008 |
| 20100021156 | SHUTTER AND CAMERA MODULE WITH SAME - A shutter includes a first light-pervious electrode, a second light-pervious electrode, a light-shielding layer sandwiched between the first and second light-pervious electrodes and a voltage supplying system. The light-shielding layer is comprised of an electrostrictive material. The light-shielding layer has a fixed end positioned adjacent to one edge of the first light-pervious electrode, and a free end facing toward the opposite edge. the free end is extendable towards the opposite edge of the first light-pervious electrode to block light from in response to a voltage applied to the light-shielding layer. The voltage supplying system is electrically connected with the first and second light-pervious electrodes for supplying a voltage between the first and second light-pervious electrodes. | 01-28-2010 |
| 20110076005 | PORTABLE ELECTRONIC DEVICE HAVING CAMERA - A portable electronic device includes a first cover, a second cover, a camera and a liquid crystal shutter. The first and second covers cooperatively form a housing. The camera is received in the housing and fixed to the first cover. The camera includes an optical lens and an image sensor. The optical lens is optically aligned with the image sensor. The second cover has a through hole defined therein aligned with the optical lens of the camera. The liquid crystal shutter is fixed in the through hole. The liquid crystal shutter is changeable between a bright state and a dark state, thereby having a light switch function of a shutter. | 03-31-2011 |

| 20080304820 | IMAGE SENSING APPARATUS AND CONTROL METHOD THEREFOR - An image sensing apparatus comprises an image sensing unit which receives an object image via a lens and accumulate the received image as an electric charge, a mechanical shutter unit which travels so as to shield an image sensing region of the image sensing unit against light, a scanning unit which performs scanning for sequentially starting the accumulation of the electric charge for each image sensing region of the image sensing unit, a control unit which controls the accumulation start scanning of the scanning unit and the travel of a shutter of the mechanical shutter unit, so as to implement a first curtain and second curtain of a shutter and a changing unit which changes a maximum shutter speed on the basis of one of a type of the lens and information on the lens. | 12-11-2008 |
| 20120275777 | FOCAL PLANE SHUTTER FOR CAMERAS - A blade room for a second blade group is formed between a shutter base plate and a middle plate and a blade room for a first blade group is formed between the middle plate and an auxiliary base plate, by separating a space between the shutter base plate and the auxiliary base plate by the middle plate. A push pin which is planted on the shutter base plate pushes a portion on the lower area of the middle plate toward the auxiliary base plate so that the middle plate bends in the shape of an arc. Also, the area of the middle plate below the exposure aperture has the narrowest width in the portion which is pushed by the push pin and the pushed portion of the middle plate has a shape by which the area of the middle plate below the exposure aperture is easy to bend. | 11-01-2012 |

| 20140363151 | THERMAL CONTROL IN VARIABLE APERTURE MECHANISM FOR CRYOGENIC ENVIRONMENT - A shutter assembly comprising a first planar member and a second planar member opposed from one another and forming a sleeve having a cavity therebetween, the sleeve having a pair of side rails adjacent the cavity along sides of the sleeve. A first shutter member having a first end is disposed in the cavity and slidingly disposed along one of the side rails, and a second shutter member having a second end is disposed in the cavity and slidingly disposed along the other side rail. The first end is opposed to the second end and is configured to be selectively advanced towards, and retracted from, the second end so as to define an aperture therebetween having a first shape when disposed in a first position, and wherein the aperture has a second larger shape when the first end is disposed in a second position. The first shutter member and the second shutter member maintain a thermal contact with the side rails and the planar members in all positions. The shutter assembly is well suited to be used at a cryogenic temperature and in a high vacuum environment. | 12-11-2014 |
| 20120321292 | ELECTROMAGNETIC SHUTTER - A shutter includes a driver ring, a plurality of shutter blades coupled to the drive ring such that movement of the drive ring transitions the plurality of shutter blades between an open position exposing a central aperture of the shutter, and a closed position blocking the central aperture, and a first stop and a second stop movable relative to the first stop. At least one of the first and second stops limits travel of the shutter blades. | 12-20-2012 |

| 20150086190 | LIGHT-QUANTITY CONTROL APPARATUS AND OPTICAL APPARATUS - A light-quantity control apparatus includes a light-quantity control blade movable along a curved path preformed between a first optical member and a second optical member, and a blade driver configured to rotate the light-quantity control blade along the curved path. A light-quantity control apparatus includes a light-quantity control blade movable along a curved path preformed between a first optical member and a second optical member, and a blade driver configured to rotate the light-quantity control blade along the curved path. The blade driver includes a rotating member configured to rotate the light-quantity control blade, and a driver connected to an outer circumferential edge portion of the rotating member. | 03-26-2015 |
