Abstract

The present application discloses an imaging lens group, a camera module, an electronic device and an automobile. The refractive powers of the first lens to the sixth lens of the imaging lens group are negative, negative, positive, positive, positive and negative in sequence. The object side of the second lens is convex and the image side is concave. The object side and the image side of the five lenses are convex, the sixth lens has a concave object side and a convex image side, and the focal length f1 of the first lens, the focal length f2 of the second lens and the effective focal length f of the imaging lens group are set to satisfy 13.40 mm<f1*f2 / f<16.44mm. By using a combination of multiple lenses, and by rationally distributing the focal length, refractive power and surface shape of each lens, the angle of the incident angle of the light from the object side entering the imaging lens group can be effectively adjusted, thereby effectively improving the imaging effect of the imaging lens group. .

Description

technical field [0001] The present application relates to the field of imaging technology, and in particular, to an imaging lens group, a camera module, an electronic device, and an automobile. Background technique [0002] Since cameras have been applied to electronic devices such as smart phones and tablet computers, with the continuous development of electronic devices, people's shooting requirements for cameras have also been continuously improved. In the related art, it is difficult to adjust the balance among various shooting requirements, such as the size of each lens group in the camera, the range of shooting angles, and the brightness of light in different fields of view, thereby affecting the imaging effect of the camera. SUMMARY OF THE INVENTION [0003] To solve the above problems, embodiments of the present application provide an imaging lens group, a camera module, an electronic device, and an automobile. [0004] In the first aspect, an imaging lens group p...
