| 20080247748 | POSITION CONTROLLER, DRIVING MECHANISM AND IMAGE PICKUP SYSTEM - In a position controller, a driving mechanism and an image pickup system according to the present invention, an operation of controlling a position of a movable member is performed by using, as a reference value, a first resistance value giving a first change point at which a resistance change rate per unit temperature change in a shape-memory-alloy member changes from a first rate to a second rate different from said first rate. Thus, the present invention makes it possible to control the position of the movable member based on a resistance of a shape-memory-alloy member, without a position sensor. | 10-09-2008 |
| 20090317072 | FOCAL PLANE SHUTTER - A focal plane shutter includes: a shutter substrate having an opening; a blade for opening and closing the opening; a drive member swingably supported for driving the blade; a drive spring for driving the drive member; and an adjustment mechanism for adjusting an urging force of the drive spring. One end of the drive spring is engaged with the drive member. The adjustment mechanism includes: an adjustment member engaging the other end of the drive spring and rotatably supported to adjust the urging force of the drive spring; and an engagement member abutting the adjustment member to stop rotation of the adjustment member. The adjustment member has a clearance portion for avoiding abutment against the engagement member at a given rotational position. | 12-24-2009 |
| 20100014850 | IMAGING DEVICE - An imaging device includes: an image pickup unit including an image pickup element and a control substrate mounted with the image pickup element; and a shutter unit including a blade for adjusting an amount of light reaching the image pickup element and a drive source for driving the blade. The shutter unit includes a terminal portion electrically connected to a coil of the drive source. The terminal portion extends outward from the shutter unit and is electrically connected to the control substrate. The terminal portion and the image pickup unit include alignment means for aligning these each other. The shutter unit is aligned with the image pickup unit via the terminal portion. | 01-21-2010 |
| 20110052184 | IMAGE SENSING APPARATUS AND CONTROL METHOD THEREOF - An image sensing apparatus comprises a shutter driving member which drives a shutter blade; a shutter spring which urges the shutter driving member; a shutter charge unit which charges the shutter spring, and is switched between an over-charged state and a travel prepared state; a driving unit which drives the shutter charge unit; a retaining unit which, when the shutter charge unit is set in the travel prepared state, retains the shutter driving member in a state in which the shutter spring is charged; a determination unit which determines whether or not the apparatus is executing a continuous shooting operation; and a controller which, when it is determined that the apparatus is executing the continuous shooting operation, controls to drive the shutter charge unit to the travel prepared state without stopping the shutter charge unit in the over-charged state after the charge operation of the shutter spring is complete. | 03-03-2011 |
| 20110243550 | SYSTEM AND METHOD FOR HIGH-SPEED SHUTTERING - A shutter system may be used as part of an imaging device, such as a CMOS imaging device. The shutter system comprises a support structure, and first and second shutter members are rotatably mounted to the support structure so as to have respective first and second axes of rotation. The first and second shutter members have respective first and second shutter apertures defined therethrough, with the first shutter apertures having a first circular orbit about the first axis of rotation and the second shutter aperture having a second circular orbit about the second axis of rotation. The first and second shutter members at least partially overlap, and the first circular orbit and the second shutter circular orbit also at least partially overlap, so that rotation of the first and second shutter members at different frequencies cycles the first and second shutter apertures into and out of registration with each other. | 10-06-2011 |
| 20120141113 | SHUTTER DEVICE - A shutter base plate is formed with a first shaft parallel to an optical axis of a photographic light flux, and a blade lever rotates about the first shaft to drive a first blade and a second blade. A drive lever rotates about the first shaft to drive the blade lever. A second cam gear rotates about a second shaft formed on the shutter base plate in parallel to the first shaft to charge a mirror drive spring. A first cam gear rotates about a third shaft formed on the shutter base plate in parallel to the first shaft to switch between a state in which the blade lever is held so that the first blade and the second blade close the aperture and a state in which holding of the blade lever is released. | 06-07-2012 |
| 20120294602 | CAMERA MODULE AND METHOD FOR MANUFACTURING CAMERA MODULE - Certain embodiments provide a camera module including a lens holder that holds a lens, a transparent substrate disposed below the lens in the lens holder, a driving-device, a substrate including a sensor unit, a driver IC, a plurality of external electrodes electrically connected to the sensor unit and the driver IC, and a wiring for the driving-device. The driving-device is a device which moves the lens in the vertical direction and which is disposed above the transparent substrate in the lens holder. The substrate is disposed below the transparent substrate in the lens holder. The driver IC is an IC which drives the driving-device and which is disposed at a rear side of the substrate. The wiring for the driving-device electrically connects the driving-device with the driver IC. | 11-22-2012 |
| 20130022346 | CAMERA WITH INFRARED SHUTTER MODULE - A camera includes an image sensor, a storing module, an infrared shutter module, and a controlling module. The image sensor converts light rays projected thereon to digital image signals. The storing module is for storing the digital image signals. The infrared shutter module includes an infrared emitter and an infrared receiver adjacent to the infrared emitter, and when infrared rays emitted from the infrared emitter are transmitted into the infrared receiver, the infrared shutter module outputs a triggering signal. The controlling module electrically connects to the image sensor, the storing module, the infrared shutter module and stores the digital image signals in the storing module when receiving the triggering signal. | 01-24-2013 |
| 20130077951 | Cascaded Electrostatic Actuator - A cascaded electrostatic actuator can be formed from a substantially planar substrate. The cascaded electrostatic actuator can be formed in a plane of the substrate. Various embodiments are described. | 03-28-2013 |
