Problems solved by technology

However, part of the incident light 270 does not directly enter the image sensor 260 through refraction, but enters the image sensor 260 after being reflected on the surface of the spacer ring 250, thereby forming glare and blurring the image. The existence of glare seriously affects the The quality of the captured image

Embodiment Construction

[0013] The lens module of the technical solution and the camera module having the lens module will be further described in detail below in combination with multiple embodiments and drawings.

[0014] Please also refer to figure 1 and figure 2 , the camera module 1 provided by the first embodiment of the technical solution includes a lens module 10 , a lens mount 20 and an image sensor 30 .

[0015] The mirror base 20 has a receiving hole 22 , the inner wall of the receiving hole 22 is provided with an internal thread. The lens module 10 and the image sensor 30 are accommodated at two sides of the receiving hole 22 . The lens module 10 is used to form optical imaging. The image sensor 30 is located on the image side of the camera module 1 , and is connected to the printed circuit board 40 to convert the digital signal of the image sensor 30 into an electrical signal and transmit it to the outside. The image sensor 30 may be a Charge Coupled Device (CCD for short) or a Com...

Abstract

The invention provides a lens module, comprising a lens barrel, a first lens, a second lens and a spacer ring. The first lens, the spacer ring and the second lens are sequentially arranged in the lens barrel along the optical axis. The spacer ring is provided with a first surface, a second surface opposite to the first surface and an inner wall connecting the first surface and the second surface, wherein, the first surface is in contact with the first lens and the second surface is in contact with the second lens; the inner wall comprises a first bevel and a second bevel, which are connected with each other; the first bevel and the first surface form an acute angle; the second bevel and the second surface also form an acute angle. The flare can be effectively reduced, thus improving the imaging quality of the lens module. The invention also provides a camera module with the lens module.

Description

technical field [0001] The invention relates to the technical field of optical systems, in particular to a lens module capable of reducing glare and a camera module with the lens module. Background technique [0002] With the multi-functional development of electronic products, camera modules are widely used in consumer electronic products such as mobile phones, notebook computers, and personal digital assistants. While pursuing multi-functionality, people also hope that electronic products have excellent image effects, that is, they hope that camera modules have high image quality. Takano, H published an article titled "Two-phase direct-drive motor built into a camcorders zoom lens barrel" on "Consumer Electronics" in February 1995, revealing a camera module with high-quality Imaging quality, while having the advantage of compact structure. [0003] A camera module is usually composed of a lens barrel with optical elements and a lens base with an image sensor. see Figur...
