Problems solved by technology

[0004] However, since the optical anti-shake system needs to increase the structure of the image stabilizer, it will increase the size of the camera module, which can only be used in high-end digital cameras in the past. The shock function can only use the electronic anti-shake system, but not the optical anti-shake system

Embodiment Construction

[0065] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

[0066] In the following description, the so-called orientations "up" and "down" are only used to represent relative positional relationships, and are not intended to limit the present invention. When referring to a first component being located on a second component, this includes situations where the first component is in direct contact with the second component or is separated by one or more other components.

[0067] In addition, in the drawings or descriptions in the specification, the same symbols are used for similar or identical parts. In the drawings, the shape or thickness of the embodiments may be exaggerated to simplify or facilitate labeling. Furthermore, components not shown or described in the drawings are forms known to those skilled in the art.

[0068] It should be understood that what is provided in the following embodiments is a ...

Abstract

An integrated structure of auto focus (AF) and optical image stabilizer (OIS) mechanisms includes a lens holder, an AF coil disposed outside of the lens holder, wherein the lens holder is suspended inthe center of a frame via a first spring, and inner edges of sidewalls of the frame are close to but do not contact an outer edge of the AF coil; a plurality of magnets disposed in four angular spaces between the frame and the lens holder and corresponding to the outer edge of the AF coil to drive the lens holder back and forth along an optical axis; a plurality of suspension elements configuredto suspend the frame in the direction of the optical axis; and a first driver board having a plurality of first hand shaking preventing coils, each of which corresponds to one of magnets to drive theframe to move laterally with respect to the optical axis.

Description

technical field [0001] The present invention relates to an integrated structure of auto focus and optical anti-shake mechanism; in particular to an integrated structure of auto focus (auto focus, AF) and optical image stabilizer (OIS) mechanism in a small camera module . Background technique [0002] Under the trend of miniaturization of camera modules, many handheld digital products (handheld devices) have built-in camera functions, such as mobile phones or tablet PCs, and more and more functions, such as Autofocus (AF), anti-shaking (anti-shaking) and other functions. [0003] The anti-shake function includes electronic image stabilizer (EIS) and optical anti-shake (OIS) systems. The Electronic Image Stabilization (EIS) system optimizes the digital image captured by the image sensor to correct the blurred image caused by the image out of focus caused by vibration (blurred images), but with limited effect. The optical image stabilization (OIS) is to add an image stabili...
