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
The present invention relates to the camera module technical field, be specifically related to a kind of camera module and base thereof.
Background technology
Conventional camera module comprises the assemblies such as base, camera lens, photo-sensitive cell and wiring board.The base of camera module as shown in Figure 1.Base inside is provided with light hole 101, and the hole wall 102 of this light hole is right-angle structure normally, and namely hole wall 102 is vertical with base end face.
As shown in Figure 2, the incident ray of camera lens can reflect at base light hole wall 102 places, and part light is reflected to the photosensitive area of photo-sensitive cell (sensor) 103, can produce dazzle (flare), disturbs normal imaging.Incident ray and reflection ray are shown in band arrow straight line among the figure.When backlight or the shooting of side backlight environment, high-intensity light source enters camera lens, and glare phenomenon can be more serious.
The structural design trend of camera module is more and more less, more and more thinner.Camera lens TTL(through thelens, by camera lens, a kind of light value) also more and more shorter, CRA(chiefray angle, key light line angle) increasing, even increase to 28 ° to 30 °.
CRA increases, and means that the incident angle of incident ray increases, and further increases so that the light quantity of reflection occurs at base light hole wall place the incident ray of camera lens, causes glare phenomenon more serious.
Summary of the invention
The embodiment of the invention provides a kind of camera module and base thereof, can produce serious glare phenomenon to solve existing camera module, disturbs the technical matters of normal imaging.
A kind of base of camera module, this base inside is provided with light hole, and the hole wall of described light hole is the dip plane, and this dip plane is towards the photo-sensitive cell of camera module.
A kind of camera module comprises camera lens, wiring board, photo-sensitive cell and aforesaid base.
The embodiment of the invention adopts the hole wall with camera module base light hole to be designed to the dip plane and to make the dip plane towards the technical scheme of photo-sensitive cell, can reduce hole wall to the reflection of camera lens incident ray, reduce or avoid the photosensitive area of incident ray arrival photo-sensitive cell, thereby alleviate or avoid glare phenomenon, reduce the interference to normal imaging.

Embodiment
The embodiment of the invention provides a kind of base of camera module, can solve existing camera module and can produce serious glare phenomenon, disturbs the technical matters of normal imaging.The embodiment of the invention also provides corresponding camera module.Below be elaborated respectively.
Embodiment one,
Please refer to Fig. 3, the embodiment of the invention provides a kind of base of camera module, and this base inside is provided with light hole 201, in the present embodiment, the hole wall 202 of this light hole adopts oblique angle structure, namely, the hole wall 202 of light hole is the dip plane, and this dip plane is towards the photo-sensitive cell 203 of camera module.
The plane at described dip plane and photo-sensitive cell place acutangulates.In a preferred embodiment, described dip plane can be parallel with the incident ray of incident angle maximum.The incident ray of described incident angle maximum is that incident angle is the incident ray of CRA.
In a kind of embodiment, camera lens is tight shot, and at this moment, described base comprises that being positioned at the top is used for the Connection Block of connection lens and is positioned at the pedestal that the below is used for the connection line plate; In the another kind of embodiment, camera lens is autofocus lens, and described camera lens is installed on the base by motor, and can stretch out under motor drives or retract.
Described base inside can arrange divider wall 204, realizes the effects such as anti-gray, and described light hole specifically can be the through hole that described divider wall middle section is offered.This through hole can be circular or square.
The inner hollow of base, the bottom surface is used for the connection line plate, and described photo-sensitive cell is positioned at the below of base light hole, and is fixed on the described wiring board.
As shown in Figure 4, when the camera lens incident ray passes through the base light hole of the embodiment of the invention, because the hole wall of light hole is downward dip plane, incident ray can be reduced reflection, especially when the dip plane is parallel with the incident ray of incident angle maximum, even do not produce reflection, thereby can reduce or avoid reflected light to arrive the photosensitive area of photo-sensitive cell, and then alleviate or avoid glare phenomenon, reduce the interference to normal imaging.
To sum up, the embodiment of the invention provides a kind of base of camera assembly, and this base adopts the hole wall with light hole to be designed to the dip plane and to make the dip plane towards the technical scheme of photo-sensitive cell, can alleviate or avoid glare phenomenon, reduces the interference to normal imaging.
Embodiment two,
The embodiment of the invention also provides a kind of camera module, and described camera module comprises camera lens, wiring board, photo-sensitive cell and such as embodiment one described base.
The base that camera module that the present embodiment provides adopts can alleviate or avoid glare phenomenon, reduces the interference to normal imaging, thereby can provide better more as effect.
Above camera module and the base thereof that the embodiment of the invention is provided is described in detail, and understands method of the present invention and core concept thereof but the explanation of above embodiment just is used for help, should not be construed as limitation of the present invention.Those skilled in the art are in the technical scope that the present invention discloses, and the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
