Abstract

The present invention provides a camera hand-shake correction device having a simple structure drive unit (actuator body). The hand-shake correction device (30) corrects hand-shake by maintaining the lens and the camera module (20) of capturing component orthogonal to the optical axis (O), and carrying out shakings around a first axis (P) and a second axis (Y) that crossly intersect so as to fix hand-shake. The hand-shake correction device (30) includes: an inner frame (32) for internally fixing the camera module (20), a middle frame (34) for freely shaking to support the inner frame (32) from its outside surrounding the first axis (P), and an outer frame (36) for freely shaking to support the middle frame from its outside surrounding the second axis (Y) , and a voice coil motor (40) disposed at the bottom of the inner frame and the outer frame. The voice coil motor (40) drives to shake the inner frame (32) and the outer frame (34) that surrounds the first axis (P) and the second axis (Y), respectively.

Description

[0001] This application is a divisional application of a Chinese patent application with an application date of September 24, 2009, an application number of 200910177610.8, and an invention title of "camera shake correction device". technical field [0002] The present invention relates to a camera shake correction device, and more particularly to a camera shake correction device capable of correcting a shake (vibration) generated when a still image is captured, so as to capture an image without image blur. Background technique [0003] Various shake correction devices (image blur correction devices) have been proposed so far, which can prevent blurring of the image on the imaging plane even if there is a shake (vibration) when shooting a still image, and enable clear shooting. [0004] For example, Japanese Unexamined Patent Application Publication No. 2006-65352 (Patent Document 1) discloses an "image blur correction device", which is composed of a plurality of lens groups ...
