摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
