Problems solved by technology

Therefore, the function of optical zoom cannot be realized. The image sensor and image processing chip enlarge and process the electrical signal related to the optical image, which is the so-called "digital zoom" function to adjust the magnification of the lens group.
[0004] Although the autofocus function or optical zoom (zoom) function is very common in existing digital cameras, it is still difficult to implement on small digital camera modules whose vertical and horizontal sizes are reduced to within a few 10mm

Abstract

Disclosed herein is a camera module. The camera module includes a bobbin unit, a suspension unit and a drive unit. The bobbin unit includes a stationary part which is fixed in a base, and a movable part which is provided so as to be movable relative to the stationary part, with a lens installed in the movable part. The opposite ends of the suspension unit are respectively connected to the stationary part and the movable part. The suspension unit includes a link unit which rotates when the movable part moves relative to the stationary part. The drive unit moves the movable part relative to the stationary part.

Description

technical field [0001] The invention relates to a camera module with a moving lens. Background technique [0002] The mobile phone has a built-in high-resolution small camera module with several million pixels. A unique compact digital camera module with high resolution. Although it is small in size, it must have the function of auto focusing or optical zoom (zoom) in order to achieve precise image quality. [0003] In order to reduce the manufacturing cost or the size of the product in the existing low-pixel camera module, the lens group is fixed in the direction of the optical axis. Therefore, the function of optical zoom cannot be realized, and the image sensor and image processing chip enlarge and process the electrical signal related to the optical image, that is, the so-called 'digital zoom' function to adjust the magnification of the lens group. [0004] Although the autofocus function or optical zoom (zoom) function is very common in existing digital cameras, it is...
