Abstract
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.
Claims16
An imaging apparatus comprising:
- a blade member configured to open and close an exposure opening;
- a drive member configured to drive the blade member;
- a first urging member configured to change the blade member to a charge state according to a rotation of the drive member;
- a motor configured to drive the drive member;
- an image sensor located at a position corresponding to the exposure opening;
- and
- a controller configured to control the motor and the image sensor,
- wherein 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, and
- wherein 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.
A control method for an imaging apparatus that includes a blade member configured to open and close an exposure opening, a drive member configured to drive the blade member, a first urging member configured to change the blade member to a charge state according to a rotation of the drive member, a motor configured to drive the drive member, and an image sensor located at a position corresponding to the exposure opening, the control method comprising the steps of controlling the motor and the image sensor,
- wherein the controlling step 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, and
- wherein the controlling step rotates the motor in a second direction reverse to the first direction after a charge of the blade member by the first urging member completed, completes reading the signal corresponding to the first imaging before opening the exposure opening, and stops rotating the motor in the second. direction.
A non-transitory computer-readable storage medium that stores a program for causing a computer to execute each process of a method for controlling an imaging apparatus that includes a blade member configured to open and close an exposure opening, a drive member configured to drive the blade member, a first urging member configured to change the blade member to a charge state according to a rotation of the drive member, a motor configured to drive the drive member, and an image sensor located at a position corresponding to the exposure opening, the control method comprising the steps of controlling the motor and the image sensor,
- wherein the controlling step 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, and
- wherein the controlling step 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.
