Abstract
The embodiment of the invention discloses a kind of base of camera module, this chassis interior is provided with light hole, and the hole wall of described light hole is dip plane, and this dip plane is towards the photo-sensitive cell of camera module.The embodiment of the present invention also provides corresponding camera module.The hole wall of camera module base light hole is designed to dip plane owing to adopting and makes dip plane towards the technical scheme of photo-sensitive cell by technical solution of the present invention, the reflection of hole wall to camera lens incident ray can be reduced, thus alleviate or avoid glare phenomenon, reduce the interference to normal imaging.
Description
Technical field
The present invention relates to 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.Chassis interior is provided with light hole 101, and the hole wall 102 normally right-angle structure of this light hole, 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 place, and some light is reflected to the photosensitive area of photo-sensitive cell (sensor) 103, can produce dazzle (flare), interference normal imaging.Incident ray and reflection ray are as being with in figure shown in arrow straight line.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(throughthelens, by camera lens, a kind of light value) also more and more shorter, CRA(chiefrayangle, key light line angle) increasing, even increase to 28 ° to 30 °.
CRA increases, and mean that the incident angle of incident ray increases, the light quantity making the incident ray of camera lens that reflection occur at base light hole wall place increases further, causes glare phenomenon more serious.
Summary of the invention
The embodiment of the present invention provides a kind of camera module and base thereof, can produce serious glare phenomenon to solve existing camera module, the technical matters of interference normal imaging.
A base for camera module, this chassis interior is provided with light hole, and the hole wall of described light hole is 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 base as above.
The hole wall of camera module base light hole is designed to dip plane and makes dip plane towards the technical scheme of photo-sensitive cell by embodiment of the present invention employing, the reflection of hole wall to camera lens incident ray can be reduced, reduce or avoid incident ray to arrive the photosensitive area of photo-sensitive cell, thus alleviate or avoid glare phenomenon, reduce the interference to normal imaging.
Accompanying drawing explanation
Fig. 1 is the sectional view of existing camera module base;
Fig. 2 is the schematic diagram that reflection occurs at base light hole inwall place camera lens incident ray;
Fig. 3 is the sectional view of the base of the camera module that the embodiment of the present invention provides;
Fig. 4 is the schematic diagram of camera lens incident ray by the base light hole of the embodiment of the present invention.
Embodiment
The embodiment of the present invention provides a kind of base of camera module, can solve existing camera module and can produce serious glare phenomenon, the technical matters of interference normal imaging.The embodiment of the present invention also provides corresponding camera module.Below be described in detail respectively.
Embodiment one,
Please refer to Fig. 3, the embodiment of the present invention provides a kind of base of camera module, and this chassis interior 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 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, the incident ray that described dip plane can be maximum with incident angle is parallel.The incident ray of the maximum incident ray of described incident angle to be incident angle be CRA.
In a kind of embodiment, camera lens is tight shot, and now, described base comprises and is positioned at top for the Connection Block of connection lens be positioned at the pedestal of below for connection line plate; In another kind of embodiment, camera lens is autofocus lens, and described camera lens is arranged on base by motor, and can stretch out under motor drives or retract.
Described chassis interior can arrange divider wall 204, realizes the effects such as anti-gray, and described light hole can be specifically the through hole that described divider wall middle section is offered.This through hole can be circular or square.
The inner hollow of base, bottom surface is used for connection line plate, and described photo-sensitive cell is positioned at the below of base light hole, and is fixed on described wiring board.
As shown in Figure 4, when camera lens incident ray passes through the base light hole of the embodiment of the present invention, hole wall due to light hole is downward dip plane, incident ray can be reduced reflection, especially when maximum with incident angle when dip plane incident ray is parallel, even do not produce reflection, thus 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, embodiments provide a kind of base of camera assembly, the hole wall of light hole is designed to dip plane and makes dip plane towards the technical scheme of photo-sensitive cell by the employing of this base, can alleviate or avoid glare phenomenon, reducing the interference to normal imaging.
Embodiment two,
The embodiment of the present invention also provides a kind of camera module, and described camera module comprises camera lens, wiring board, photo-sensitive cell and the base as described in embodiment one.
The base that camera module that the present embodiment provides adopts can alleviate or avoid glare phenomenon, reduces the interference to normal imaging, thus can provide better more as effect.
The camera module provided the embodiment of the present invention above and base thereof are described in detail, but the explanation of above embodiment just understands method of the present invention and core concept thereof for helping, and 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 change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.
