Problems solved by technology

[0002] In related technologies, the zoom lens can realize the change of the overall focal length through the movement of the lens group. However, most of the current driver chips are only suitable for realizing the focus of the fixed-focus lens. The output accuracy is not high
However, in the zoom lens, the movement range of the lens group of the zoom lens is relatively large. If the above-mentioned driving chip for focusing is used to control the movement of the lens group of the zoom lens, the movement accuracy of the lens group will be reduced.

Abstract

The invention discloses a zoom lens, a camera module and an electronic device. The zoom lens includes a shell, a first lens assembly, a second lens assembly, a third lens assembly, and a driving chip.The first lens assembly, the second lens assembly and the third lens assembly are arranged in the shell. The driving chip comprises a first control end and a second control end, and the first controlend is connected with the second lens assembly to control the second lens assembly to move relative to the first lens assembly along the optical axis; the second control end is connected with the third lens assembly to control the third lens assembly to move relative to the first lens assembly along the optical axis; the effective control bit of the driving chip is greater than or equal to a predetermined value so that the minimum movement unit of the zoom lens conforms to the predetermined movement precision. According to the zoom lens provided by the embodiment of the invention, the effective control bit of the driving chip is greater than or equal to the predetermined value so that high-precision movement of the lens assembly of the zoom lens during zooming can be realized.

Description

Technical field [0001] This application relates to the technical field of consumer electronics, in particular to a zoom lens, a camera module and an electronic device. Background technique [0002] In the related art, the zoom lens can realize the change of the overall focal length through the movement of the lens group. However, most of the current driving chips are only suitable for realizing the focusing of the fixed-focus lens. Because the lens group moves within a small range during focusing, the driving chip The output precision is not high. However, in a zoom lens, the movement range of the lens group of the zoom lens is relatively large. If the above-mentioned driving chip for focusing is used to control the movement of the lens group of the zoom lens, the movement accuracy of the lens group will be reduced. Summary of the invention [0003] The embodiments of the present application provide a zoom lens, a camera module, and an electronic device. [0004] The zoom lens of ...
