Abstract

The invention relates to a camera assembly, a camera module and a mobile terminal. The camera assembly includes, in order from an object side to an image side: a diaphragm; a first lens has positive refractive power, wherein the object side surface of the first lens is a convex surface at the optical axis, and the image side surface of the first lens is a concave surface at the optical axis; a second lens with positive refractive power, wherein both the object-side surface and the image-side surface of the second lens are convex at the optical axis; a third lens with negative refractive power;a fourth lens with positive refractive power having a convex image-side surface at the optical axis; a fifth lens with refractive power; a sixth lens that has negative refractive power, the object side surface of the sixth lens is a convex surface at the optical axis, the image side surface of the sixth lens is a concave surface at the optical axis, the object side surface and the image side surface of the sixth lens are aspheric surfaces, and at least one inflection point is arranged on the object side surface and the image side surface of the sixth lens. When the ranges of ImgH * tan (HFOV) / f and R41 / OAL are satisfied, the camera assembly has a large imaging area and low sensitivity.

Description

technical field [0001] The invention relates to the field of photography and imaging, in particular to a camera assembly, a camera module and a mobile terminal. Background technique [0002] In recent years, with the rise of electronic products with photographic functions, the requirements for the imaging quality of the lens have become more and more stringent. The photosensitive element of the general optical system is nothing more than a photosensitive coupling device (Charge Coupled Device, CCD) or a complementary metal oxide semiconductor element (Complementary Metal-Oxide Semiconductor Sensor, CMOSSensor), and the pixel size of the electronic photosensitive element is limited Due to the development of semiconductor manufacturing process, in order to have higher pixels, the chip generally adopts a larger size, so a camera lens with a large imaging area is required to match the chip and improve the imaging quality. [0003] In addition, traditional optical systems mounte...
