AI Technical Summary

Technical Problem

The imaging systems of existing electronic devices adopt a dual-lens discrete design, which results in high manufacturing costs and makes it difficult to achieve a thinner and lighter design, thus failing to meet the demand for miniaturization.

Method used

It adopts an optical zoom lens design, and achieves continuous switching between main camera mode and telephoto mode by moving and inserting the first lens group, the second lens group and the third lens group, reducing the number of lens modules, and optimizing aberration correction and light propagation by combining lens combinations with positive and negative refractive forces.

Benefits of technology

It enables state switching within a single optical zoom lens, reducing manufacturing costs and assembly difficulty, while improving image quality and field of view, adapting to different shooting needs, and meeting the miniaturization and high-quality imaging requirements of electronic devices.

Abstract

The application discloses an optical zoom lens, a camera module and an electronic device. The optical zoom lens can be continuously switched between a main camera state and a long-focus state, can meet the miniaturization requirement, effectively reduces the manufacturing cost, and realizes high-quality imaging. When the optical zoom lens is switched from the main camera state to the long-focus state, the first lens group and the second lens group are moved in the direction away from the imaging surface along the optical axis to zoom the optical zoom lens, and the third lens group is inserted between the second lens group and the imaging surface. The optical zoom lens satisfies the following relationship: 1.30<FOVl / FOVs<1.35, 1.40<FNOs / FNOl<1.45; wherein, FOVs is the maximum field of view angle of the optical zoom lens in the main camera state, FOVl is the maximum field of view angle of the optical zoom lens in the long-focus state, FNOs is the aperture number of the optical zoom lens in the main camera state, and FNOl is the aperture number of the optical zoom lens in the long-focus state.
