A blade opening/closing apparatus includes: a base body that includes an aperture; a driving body that is movably supported by the base body and is operated by a driving force of a drive source; an opening/closing blade that is moved by an operation of the driving body and opens/closes the aperture; and a braking body that controls a movement speed of the opening/closing blade via the driving body, the driving body including, on one surface thereof, an engagement portion that is to be engaged with the opening/closing blade and transmits the driving force to the opening/closing blade, the driving body including, on another surface thereof, a braked portion to which a braking force of the braking body is to be applied.

Photographic Synchronization Optimization System and Method

A system and method for synchronizing a photographic lighting device to image acquisition by a camera using light emission profile information to position a light emission profile at a desired location in an image acquisition window. A light energy balance point of a light emission profile can be used to position the balance point at a desired location in an image acquisition window. 1. A method of synchronizing a photographic lighting device to image acquisition by a camera , the camera generating one or more detectible signals and/or events between a first time at which the camera is triggered to start an image acquisition sequence and a second time at which the camera begins capture of an image from light incident upon an imaging sensor of the camera for the image acquisition sequence , the image acquisition sequence being at a first shutter speed setting of the camera , the photographic lighting device having a flash emission profile , the method comprising:receiving a user offset value from a user input interface, the user input interface being at least one of an interface of the camera and an interface of a wireless synchronizer located external to the camera, the user offset value relating to an offset of a position of the flash emission profile of the photographic lighting device within an image acquisition window for the image acquisition;based on the occurrence of a first camera signal and/or event occurring between the first and second times, wirelessly communicating a wireless signal from the camera to the photographic lighting device, the first camera signal and/or event not being a signal or event intended by the camera for instructing the initiation of an X-sync lighting emission at the standard X-sync time for the camera; andbased on the first camera signal and/or event, the wireless signal, the first shutter speed setting, and flash emission profile information for the photographic lighting device stored in a memory of at least one of the camera and ...

FOCAL-PLANE SHUTTER AND OPTICAL APPARATUS

A focal-plane shutter capable of preventing deterioration of the quality of a captured image is provided. A focal-plane shutter includes a base plate having an opening, a rear curtain that moves between an open position where the opening is open and a closed position where the opening is closed to allow the opening to be open and closed, and a first cushioning member that comes into contact with the rear curtain, and the rear curtain has a first protrusion that is located outside the opening, protrudes in a first direction from the open position toward the closed position, and comes into contact with the first cushioning member when the rear curtain moves from the open position to the closed position. 1. A focal-plane shutter comprising:a substrate having an opening;a curtain that moves between an open position where the opening is open and a closed position where the opening is closed to allow the opening to be open and closed; anda cushioning member that comes into contact with the curtain,wherein the curtain has a protrusion that is located outside the opening, protrudes in a first direction from the open position toward the closed position, and comes into contact with the cushioning member when the curtain moves from the open position to the closed position.2. The focal-plane shutter according to claim 1 ,wherein the curtain includes a front curtain and a rear curtain, andthe rear curtain is provided with the protrusion.3. The focal-plane shutter according to claim 2 ,wherein the front curtain comes into contact with the cushioning member when the front curtain moves from the closed position to the open position.4. The focal-plane shutter according to claim 1 ,wherein the curtain includes a front curtain and a rear curtain, andthe front curtain is provided with the protrusion.5. The focal-plane shutter according to claim 1 ,wherein the protrusion is provided at an end portion of the curtain along a second direction perpendicular to the first direction.6. The ...
