Abstract

The present invention relates to a lens, comprising an independent first lens unit and at least one independent second lens unit arranged and fixedly connected with the first lens unit; the first lens unit or the second lens The unit has a lens with variable focal length. The close-range imaging of the lens is realized by adopting the lens whose focal length can be changed, and no additional lens or redundant components are needed, thereby saving hardware cost and hardware quantity. The zooming speed of the lens is fast and convenient, thereby reducing the design requirements of the lens and making the image of the camera module clearer. The lens is used in the lens, which can realize the continuous zoom of the camera module, and the image quality is good. The use of lenses is equivalent to replacing the corresponding fixed-focus lenses in the lens, avoiding the increase in the number of lenses in the lens, thereby avoiding the increase in the overall height or volume of the lens.

Description

technical field [0001] The invention relates to a lens, in particular to a lens with a variable focal length lens; and a camera module including the lens. Background technique [0002] The camera module of the current mobile phone realizes the optical zoom function, and generally adopts the periscope method. This method uses two or more groups of long and short focal length lenses to achieve optical zoom of a specific magnification. At the same time, the digital zoom is integrated through a certain algorithm to achieve the purpose of zooming. In the prior art, the zooming of individual camera modules achieves the zoom function of a single lens through the movement of the lens inside the lens to achieve the focal length change. However, due to the size limitation of mobile phones, this solution is difficult to be widely used, and the market value is not high. In addition, when shooting close range, it mainly depends on the design strength of the lens. Due to the limitation...
