Abstract: An image blur correction device includes an acceleration sensor, an angular velocity sensor, and a system control unit that calculates rotational acceleration components which are included in detected accelerations and are generated by rotation of a digital camera around a rotation axis parallel to an optical axis, and corrects blurs of the captured image signal in directions based on accelerations obtained by subtracting the rotational acceleration components from the accelerations detected by the acceleration sensor. The system control unit selects one of rotation axes based on a usage state of the digital camera, and calculates the rotational acceleration components generated by the rotation of the digital camera around the selected rotation axis based on an angular velocity and distances in the directions from the selected rotation axis to the acceleration sensor.

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.

Abstract: In one aspect of the present invention, when reset of a camera is received, a pan motor and a tilt motor of a pan and tilt mechanism are rotated in a first preset rotation direction, and the pan and tilt mechanism is first moved to a pan reference position and a tilt reference position. Thereafter, the pan motor and the tilt motor are rotated in a second rotation direction opposite to the first rotation direction, and the pan and tilt mechanism is moved to an initial pan position and an initial tilt position. Using a movement of the pan and tilt mechanism to initial pan and tilt positions, detection of a subject for automatic tracking is performed, and if the subject is detected, then transition to an automatic tracking state is caused to occur.

Abstract: Provided are an imaging device and a focusing control method capable of preventing a focusing error even in a case where still image capturing is consecutively performed to enhance imaging quality. A digital camera performs a correlation operation of two images captured by a pixel pair P1 after performing an imaging process of an N-th frame, and determines a reliability of a correlation operation result based on the result of the correlation operation. In a case where the reliability is low, the digital camera performs a focusing control based on a contrast AF method in each time of imaging subsequent to an (N+1)-th frame, and in a case where the reliability is low, the digital camera performs a focusing control based on a phase difference AF method in an imaging process of the (N+1)-th frame.

Abstract: The imaging device includes: a first display section that functions as an electronic view finder; a viewing angle setting section that sets a viewing angle of a live view image; a display image generation section that generates a display image which uses the live view image reduced in accordance the viewing angle; a display timing control section; and a blanking time period setting section. The display timing control section synchronizes the image sensor and the first display section in a delay time shorter than a single frame period. The blanking time period setting section sets a blanking time period at the end of the single frame period in accordance with a size of the live view image to be displayed. By completing reading of the imaging signal before start of the blanking time period, synchronization between the timing of driving the image sensor and the timing of performing display on the electronic view finder is maintained.
