Abstract

The present invention provides an obscurity correcting device which can shoot at any condition and uses a vibration wave motor, and a camera using the obscurity correcting device. The number that a deviation exceeds a preset threshold value is counted, wherein the deviation is a difference between a target drive position computed based on the obscure signals detected by an X axis gyroscope sensor (350x) and a Y axis gyroscope sensor (350y) and a position detection value detected in a position detecting sensor (353), if the count result reaches a preset count value, the obscurity correcting device is judged at unsteady state, and Tucom (402) executes control to stop the obscurity correction.

Description

technical field

[0001] The present invention relates to a blur correction device and an imaging device, and more particularly, to an imaging device having a blur correction function for preventing image blur caused by shaking. Background technique

[0002] Conventionally, imaging devices having a blur correction function include, for example, cameras. The blur correction function included in the camera is as follows, and uses a blur detection unit such as an angular velocity sensor (sensor) to detect vibration in the pitch direction and vibration in the yaw direction of the camera. The angular velocity sensor generally adopts a vibration gyroscope (vibratory gyroscope). And, based on the detected shake (vibration), a part of the lens or the imaging element of the imaging optical system is moved in a direction that cancels the shake (vibration) in a plane perpendicular to the imaging optical axis, thereby correcting the vibration formed on the imaging element. Image blur (b...
