Title:
ACTUATOR AND CAMERA DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/051918
Kind Code:
A1
Abstract:
Provided are an actuator and a camera device, with which the rotational driving of a movable unit in three directions relative to a stationary unit can be controlled while the number of components needed to detect the roll-direction rotational angle is minimized. A drive control part (110) of an actuator (2) controls rotation of the movable unit in a pitch direction on the basis of the results of detection by a first magnetic sensor (92a) and a first gyro sensor (93a). The drive control part (110) controls rotation of the movable unit in a yaw direction on the basis of the results of detection by a second magnetic sensor (92b) and a second gyro sensor (93b). The drive control part (110) controls rotation of the movable unit in the roll direction on the basis of the the results of detection by a third gyro sensor (401).
