Title:
デジタルカメラ及びデジタルカメラの制御方法
Document Type and Number:
Japanese Patent JP6571877
Kind Code:
B2
Abstract:
Provided are a digital camera and a control method of a digital camera which are capable of reducing power consumption in a focal-plane shutter capable of performing a normal opening operation. In the focal-plane shutter capable of performing the normal opening operation, in a case where a shutter release switch is operated, exposure using an electronic shutter is started. Thereafter, curtain running preparation for magnetizing a front-curtain electromagnet and a rear-curtain electromagnet and unlocking a second front-curtain drive member and a rear-curtain drive member locked in charge positions by a lock mechanism, which is a curtain running preparation operation of the focal-plane shutter, is performed immediately before exposure of a still image is completed. The exposure is ended by demagnetizing the rear-curtain electromagnet after the curtain running preparation is ended and causing rear curtains to run in a closing direction through the rear-curtain drive member by a biasing force of a rear-curtain running spring. Accordingly, an electrical conduction time of the rear-curtain electromagnet is shortened, and thus, power consumption is reduced.
