Problems solved by technology

However, the method of compensating for distortion through algorithms has the risk of loss of resolution, and real-time correction in video application scenarios or photo preview mode needs to consume system resources, which poses great challenges to device power consumption, heat dissipation, and processing speed.

Embodiment Construction

[0078] For the convenience of understanding the optical lenses provided by the embodiments of the present application, the relevant terms involved in the present application are explained:

[0079] The optical axis is an axis passing through the center of each lens.

[0080] Taking the lens as the boundary, the side where the subject is located is the object side, and the surface of the lens close to the object side is called the object side.

[0081] Taking the lens as the boundary, the side where the image of the object is located is the image side, and the surface of the lens close to the image side is called the image side.

[0082] Positive refractive power, also known as positive refractive power, means that the lens has a positive focal length.

[0083] Negative power, also known as negative refractive power, means that the lens has a negative focal length.

[0084] The focal length, also known as the focal length, is a measure of the concentration or divergence of li...

Abstract

An optical lens (45), a camera module (40) and electronic equipment (100). The optical lens (45) comprises a first lens (451), a second lens (452), a third lens (453), a fourth lens (454), a fifth lens (455) and Sixth lens (456). The first lens (451), the third lens (453) and the fifth lens (455) all have positive refractive power, the second lens (452) and the fourth lens (454) all have negative refractive power, and the sixth lens ( 456) has positive or negative power. The object side and the image side of the first lens (451) to the sixth lens (456) include at least one non-rotationally symmetrical aspherical surface. The optical lens (45) is applied to the camera module (40) and the electronic device (100), and the camera module (40) and the electronic device (100) can achieve ultra-wide-angle shooting while solving the problem of ultra-wide-angle shooting to a greater extent. Distortion problems in imaging.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 202010480875.1 and the application name "Optical Lens, Camera Module and Electronic Equipment" filed with the China Patent Office on May 30, 2020, the entire contents of which are incorporated herein by reference Applying. technical field [0002] The present application relates to the field of lenses, and in particular, to an optical lens, a camera module and an electronic device. Background technique [0003] In recent years, the demand for mobile phone photography has been increasing, especially the popularization of large-size, high-pixel CMOS (complementary metal oxide semiconductor, complementary metal oxide semiconductor) chips. Imaging quality puts forward more stringent requirements. However, traditional mobile phones have obvious distortion problems in imaging. At present, in order to solve the problem of distortion, the distortion is generally reduced by mea...
