Camera module with anti-shake device

Abstract

The present invention relates to a camera module with an anti-shake device. The camera module with an anti-shake device comprises: a lens unit that includes plural lenses for converting a subject image at a certain magnification; a housing that accepts the lens unit so that the lens unit may be driven in an optical axis direction; an automatic-focus driving unit that is installed between the lens unit and the housing to drive the lens unit in the optical axis direction; a suspension member that supports the housing in parallel to the optical axis direction so that the housing may move in the direction perpendicular to the optical axis direction; a box-shaped case that accepts the housing and includes the suspension member fixed thereto; a circuit board that is installed at the lower portion of the case and includes an image sensor; ; and a compensating actuator that is installed between the housing and the case to compensate the displacement caused by the shaking of the housing.

Description

technical field [0001] The present invention relates to a camera module equipped with a vibration compensation mechanism, and more particularly to an implementation of a camera module equipped with a vibration compensation mechanism capable of preventing the focal length of a camera (ie, a camera module equipped with a vibration compensation mechanism) The shake compensation mechanism enables the thickness of the camera to be reduced due to the shake of the hand holding the camera during use of the camera, since the shake compensation mechanism is provided next to the lens unit, and the shake compensation mechanism makes it possible to operate the autofocus The amount of current required by the AF actuator unit is minimized because the weight supported by the AF actuator unit is reduced. Background technique [0002] Most conventional shake compensation mechanisms have been implemented in size-flexible digital cameras, rather than in mobile devices (eg, mobile phones). Howe...

Problems solved by technology

[0007] However, when the user's hand holding the camera module shakes, the target image 54 moves to a different position 55, so the focal length of the camera shakes, resulting in a blurred phenomenon of the target image.

[0008] Although the above-mentioned problems are sometimes alleviated by using a stand for preventing camera shake, the camera stand is inconvenient to the average user due to its large size, heavy weight and complicated method of use

Due to the above-mentioned inconvenience of the camera mount, when the user tries to capture an image without using the camera mount, the focal length of the camera module becomes blurred due to the shaking of the user's hand, thus degrading the quality of the captured image

[0009] The above-mentioned problems not only fail to meet consumer demands for easy-to-use cameras and high image quality, but also generate expenses caused by processing low-quality photos
