A shutter apparatus includes a shutter base plate having an opening, a light shielding member movable to provide a closed state for closing the opening and an open state for opening the opening, and at least one processor or circuit configured to perform operations of a control unit configured to control the light shielding member configured to reciprocate relative to the opening so as to move the light shielding member in a first direction for a forward exposure and in a second direction opposite to the first direction for a return exposure. The control unit varies an exposure correction amount of the light shielding member between the forward exposure and the return exposure.

Shutter apparatus, imaging apparatus, control method of shutter apparatus, and storage medium

An imaging apparatus includes a controller configured to control a motor and an image sensor. The controller rotates the motor in a first direction as reading of a signal corresponding to first imaging starts for one frame using the image sensor, and charges the first urging member and the blade member. The controller rotates the motor in a second direction reverse to the first direction after a charge of the blade member by the first urging member is completed, completes reading the signal corresponding to the first imaging before opening the exposure opening, and stops rotating the motor in the second direction.

Imaging apparatus, control method for the imaging apparatus, and storage medium

A shutter apparatus includes a blade member, a blade moving member, a locking member, a cam member, and a restriction member. The cam member moves the locking member from the locking position to the non-locking position so that the blade moving member moves from the closing position to the opening position. The restriction member moves from the non-restriction position to the restriction position after the blade moving member moves from the closing position to the opening position. The cam member moves the locking member in a direction opposite to a direction from the non-locking position to the locking position so that the locking member moves the restriction member from the restriction position to the non-restriction position.

Shutter apparatus and image pickup apparatus

An image-pickup apparatus includes a driving member for leading blades configured to drive a leading blade group, a driving member for trailing blades configured to drive a trailing blade group, a cam member configured to rotate the driving member for leading blades and the driving member for trailing blades, a motor configured to drive the cam member, and a controller configured to control the motor. The controller applies a second voltage that is lower than a first voltage applied in releasing the driving member for leading blades to the motor when the driving member for trailing blades is released at normal shooting, and a third voltage that is lower than the first voltage and that is higher than the second voltage to the motor when the driving member for trailing blades is released at live view shooting.

Image-pickup apparatus having shutter apparatus

An apparatus includes an image sensor unit, a retaining member configured to retain the image sensor unit on a photographer side and to retain an optical member on an object side, a first sealing member configured, when the image sensor unit is mounted on the retaining member, to form a closely sealed space by sealing between the image sensor unit and the retaining member, the first sealing member being provided on the photographer side of the retaining member, and a second sealing member configured, when the optical member is mounted on the retaining member, to form a closely sealed space by sealing between the optical member and the retaining member, the second sealing member being provided on the object side.

Connector jacks are surface-mounted on one surface of a substrate. A reinforcing member reinforces the connector jacks. On the reinforcing member, a first reinforcing part, which is in contact with the back of the surface of the substrate on which the connector jack is mounted, and second reinforcing parts, which elastically urge the top surface of the connector jacks, are formed.

Electronic apparatus

A focal-plane shutterincludes a leading blade driving memberrotatably fitted onto a first shaftand driven by a biasing force of a leading blade driving spring, a trailing blade driving memberrotatably fitted onto a second shaftand driven by a biasing force of a trailing blade driving spring, a leading blade adjusting memberrotatably fitted onto the first shaftand adjusting the biasing force of the leading blade driving spring, a trailing blade adjusting memberrotatably fitted onto the second shaftand adjusting the biasing force of the trailing blade driving spring, and an upper base plateincluding a first surfaceand a second surfacethat are thrust position limiters. An area of the first surfaceis larger than that of the second surface

Focal-plane shutter and image pickup apparatus

A control method for a mechanical shutter in an image sensing apparatus that has the mechanical shutter which includes and a second curtain held in a pre-travel initial position using electric power, that performs image sensing using an image sensor, and that has an electronic viewfinder function. The voltage of the electric power for holding the second curtain is reduced during execution of the electronic viewfinder function, the voltage of the electric power for holding the second curtain is raised if a shutter speed set for image sensing is faster than a preset period in a case where still image sensing is instructed, and the second curtain is made to travel when a period corresponding to the shutter speed has elapsed.

Mechanical shutter control method and image sensing apparatus

A first cam gear (a shutter cam gear) and a second cam gear (a mirror cam gear) are driven to successively realize a first phase (a stop phase), a second phase (a live view phase), and a third phase (a shooting phase).

An image memory apparatus includes a unit for storing input image information, a unit for designating a storing capacity of the storing unit for the input image information, and a control unit for performing storing control of the storing unit for the input image information in accordance with an instruction from the designating unit.

Image memory apparatus

The present invention is to allow display based on the setting positions of devices in selection of a desired device to be used, and facilitate selection considering the setting positions of the devices. The present invention can also display equipments so as to allow discrimination between an equipment included in an image processing apparatus and an equipment connected on a communication line. Equipments in a network environment are placed on the first floor (1F), the second floor (2F), and the third floor (3F) in a building and connected through a network (LAN ). For example, a computer ( ) collects device information including status information and setting position information from usable input/output devices. For example, status information representing &ldquo;BUSY&rdquo; and setting position information representing &ldquo;3F-B block&rdquo; are transferred from a virtual optical scanner ( ). The computer ( ) displays the connected input/output devices together with the setting position information obtained from the devices. An image processing apparatus ( ) has various input/output devices including a reader unit ( ), a printer unit ( ), and an image input/output control unit ( ). In addition, various input/output equipments (two optical scanner devices ( ) and three facsimile transmission/reception devices ( )) are connected to the image processing apparatus ( ) through a LAN interface unit ( ) and the LAN ( ). A CPU ( ) of a core unit ( ) manages the input/output equipments to determine whether they are connected through the network. When a desired input/output equipment is to be selected, whether the input/output equipments are connected through the network is explicitly indicated.
