Abstract

An optical system, camera module and electronic equipment, the optical system sequentially includes from the object side to the image side along the optical axis: the first lens to the seventh lens with refractive power, and the second lens, the fifth lens and the sixth lens Having positive refractive power, the first lens, the third lens, the fourth lens and the seventh lens have negative refractive power. The object side and the image side of the second lens, the fifth lens and the sixth lens are convex at the near optical axis; the object and image sides of the third lens and the fourth lens are concave at the near optical axis; the first The image side of the lens is concave at the near optical axis; the object side of the seventh lens is concave at the near optical axis. By rationally designing the surface shape and refractive power of each lens in the optical system, it is beneficial to meet the characteristics of having a large image surface and a large aperture.

Description

technical field [0001] The invention belongs to the technical field of optical imaging, and in particular relates to an optical system, a camera module and electronic equipment. Background technique [0002] In recent years, with the continuous improvement of the country's requirements for road traffic safety, the demand for the degree of intelligentization of automobiles has also continued to increase. By installing the front-view camera of the vehicle camera, the front vehicle collision avoidance warning and lane departure warning can be realized, which is conducive to improving traffic safety. [0003] The front-view camera includes a multi-eye camera. Among them, the trinocular camera is composed of a front-view wide-view camera, a main-view camera and a narrow-view camera. As the main camera, the field of view camera can cover most traffic scenes. However, the size of the current main-view camera is small, and the aperture of the lens is not large enough, which affect...
