摘要： An imaging system includes a digital camera and illuminating devices. The digital camera includes an imaging optical system, a shutter, a shutter driving mechanism, an imaging element, an illumination control unit, and a wireless I/F. The shutter is a focal-plane shutter. In a case in which a main imaging operation is performed in a plural illumination control mode, the shutter driving mechanism drives the shutter to generate a transition period for which a partial exposure region is transferred to the lower side of an imaging area of the imaging element over time. The illumination control unit controls the emission times of the illuminating devices to be different times within the transition period.

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： An imaging apparatus is provided, including a blade-driving device and a driving control unit which drives the front curtain actuator and the rear curtain actuator. The front curtain and the rear curtain are positioned at the open position at a time of start and termination of imaging, in which the front curtain moves from the closing position to the open position, and the rear curtain moves from the open position to the closing position, thereby performing an exposure operation. During consecutive photographing, the front curtain positioned at the closing position is moved once in a direction of the open position and is then returned to the closing position after the rear curtain is moved to the open position after termination of the exposure operation, and before a subsequent exposure operation is performed.

摘要： A focal plane shutter includes: a bottom board having an opening portion; blade members; main driving members biased in the direction of carrying out a shutter operation of the blade members; a setting member that sets the main driving member to a setting position prior to the shutter operation, against the biasing force; following driving members connected to the blade members, biased to follow the main driving members, and moved by being pushed by the main driving members at the shutter operation; and a constraining mechanism that constrains movement of the following driving member so that the blade members are held in the closed state. The constraining mechanism engages the following driving member biased to constrain the movement thereof, and also includes a constraining member that moves to release the constraint on the main driving member through the engagement thereof prior to the setting member completing the setting operation.
