Embodiment 1

[0016] Please refer to image 3 , the embodiment of the present invention provides a base of a camera module, the base is provided with a light hole 201 inside, in this embodiment, the hole wall 202 of the light hole adopts an oblique structure, that is, the hole wall of the light hole 202 is an inclined surface, and the inclined surface faces the photosensitive element 203 of the camera module.

[0017] The inclined surface forms an acute angle with the plane where the photosensitive element is located. In a preferred embodiment, the inclined surface may be parallel to the incident light with the largest incident angle. The incident light with the largest incident angle is the incident light with an incident angle of CRA.

[0018] In one embodiment, the lens is a fixed-focus lens, and at this time, the base includes a connection seat located above for connecting the lens and a base located below for connecting the circuit board; in another embodiment, the lens is an automat...

Embodiment 2

[0024] The embodiment of the present invention also provides a camera module, the camera module includes a lens, a circuit board, a photosensitive element and the base as described in the first embodiment.

[0025] The base used in the camera module provided in this embodiment can reduce or avoid the glare phenomenon and reduce interference to normal imaging, thereby providing a better more image-enhancing effect.

Abstract

The embodiment of the invention discloses a base of a camera module. A light through hole is arranged in the base, the hole wall of the light through hole is of an inclined plane, and the inclined plane faces towards a photosensitive element of the camera module. The embodiment of the invention further provides the corresponding camera module. According to the technical scheme disclosed by the invention, as the hole wall of the light through hole of the base of the camera module is designed to be the inclined plane and the inclined plane faces towards the photosensitive element, the reflection of incident light from a lens by the hole wall can be reduced, the glare phenomenon can be further reduced or avoided, and the interference to normal imaging can be also reduced.

Description

technical field [0001] The invention relates to the technical field of camera modules, in particular to a camera module and its base. Background technique [0002] A conventional camera module includes components such as a base, a lens, a photosensitive element, and a circuit board. The base of the camera module is as figure 1 shown. A light hole 101 is provided inside the base, and the hole wall 102 of the light hole is generally a right-angle structure, that is, the hole wall 102 is perpendicular to the bottom surface of the base. [0003] like figure 2 As shown, the incident light of the lens will be reflected at the light hole wall 102 of the base, and part of the light will be reflected to the photosensitive area of ​​the photosensitive element (sensor) 103, which will generate flare and interfere with normal imaging. The incident ray and reflected ray are shown by the arrowed line in the figure. When shooting in a backlight or side backlight environment, high-int...
