Embodiment Construction

[0020] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] Such as figure 1 As shown, the large-aperture high-pixel camera module at least includes a lens, a base matched with the lens, and a photosensitive device arranged on the base for receiving optical signals from the lens. The lens is provided with an optical system along the The optical axis is arranged sequentially from the object plane to the image plane 8: a first lens 1 , a second lens 2 , a third lens 3 , a fourth lens 4 , a fifth lens 5 and a sixth lens 6 .

[0022] The object plane side of the first lens 1 is a convex surface, the image plane side is a conc...

Abstract

The embodiment of the invention discloses a large-aperture high-pixel camera module group, and the module group at least comprises a lens, a pedestal, and a light sensing device. The interior of the lens is provided with an optical system, and the optical system is sequentially provided with a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from the object space to the image space. The object plane of the first lens is a convex surface, and the image plane of the first lens is a concave surface. The object plane of the second lens is a convex surface, andthe image plane of the second lens is a concave surface. The object plane of the third lens is a convex surface, and the image plane of the third lens is a concave surface. The fourth lens is a biconvex lens. The fifth lens is a biconvex lens. The object plane of the sixth lens is a concave surface, and the image plane of the sixth lens is a convex surface. The fifth lens and the sixth lens form acombined lens, and meet a condition: TTL / EFL<=4.5. According to the invention, a lens cone mainly consists of the six lenses, and the number of lenses is small, and the structure is simple. The module group employs the combination of different lenses, and the fourth and fifth lenses are bonding lenses. The module group is large in aperture, is high in pixel, is low in distortion, and is good in athermalization.

Description

Technical field: [0001] The invention relates to a camera module, in particular to a camera module with a large aperture and high pixels. Background technique: [0002] With the application and popularization of car safety driving systems, car camera modules have also been widely used. The camera module used in the electronic rearview mirror of the car is required to be able to adapt to clear images in day and night environments, so the camera module needs to consider a large aperture; at the same time, in order to meet the details of the surrounding environment, the camera module Higher clarity is required. In order to meet the above requirements and overcome the common defects of too many lenses and complex structures in the existing vehicle-mounted camera modules, a camera module with a large aperture and high pixels is proposed. Invention content: [0003] In order to overcome the problems of too many lenses and complicated structure in the existing vehicle-mounted c...
