Abstract
The invention provides a camera module. The camera module comprises a lens, a support, a light-sensitive chip and a circuit board, wherein the support is used for fixing the lens, the light-sensitive chip is located at the bottom of the lens, and the circuit board is electrically connected with the light-sensitive chip. The window edge of the support is provided with a light shielding layer, so that the situation that light is reflected by the window edge of the support to enter the camera module is avoided. Thus, through the light shielding layer, the phenomenon that the light enters the camera module through the window edge of the support, imaging is conducted through the light-sensitive chip, and therefore stray light occurs in a shot image is avoided.
Description
Technical field
The present invention relates to technical field of electronic equipment, more particularly, relate to a kind of camera module.
Background technology
Along with the development of electronic equipment, on the electronic equipments such as computer, digital camera or mobile phone, camera module is all installed, to take pictures or to record a video.Existing camera module, as shown in Figure 1, comprise the support 11 of camera lens 10, fixed lens 10, wherein, camera lens 10 is positioned at the window of support 11, this camera module also comprises the sensitive chip 12 that is positioned at camera lens 10 bottoms, and this sensitive chip 12 is electrically connected with the electrode at two ends by gold thread, and is connected with the circuit board 13 of bottom by this electrode.
But existing camera module, in the time of photographic images, there will be veiling glare phenomenon, camera module is in the time taking the intense light sources such as the sun or fluorescent lamp, and the marginal portion of the picture of shooting there will be the stray lights such as obvious redness, white, or the phenomenon such as dazzle.Inventor studies discovery, cause the reason of this problem to be mainly, camera module is in the time of photographic light sources, light can form at the inwardly protruded A of the window edge of support place reflection, light after reflection can incide the photosurface imaging of sensitive chip, as shown in Figure 1, thus make take image in there is veiling glare phenomenon.
Summary of the invention
In view of this, the invention provides a kind of camera module, the veiling glare phenomenon occurring when the photographic images to solve camera module of the prior art.
For achieving the above object, the invention provides following technical scheme:
A kind of camera module, comprise the support of camera lens, fixed lens, the sensitive chip that is positioned at camera lens bottom and the circuit board being electrically connected with described sensitive chip, wherein, the window edge of described support has light shield layer, to stop that light is entered described camera module by the reflection of the window edge of described support.
Preferably, described light shield layer is light-absorbing coating.
Preferably, described light-absorbing coating is black light-absorbing material.
Compared with prior art, technical scheme provided by the present invention has the following advantages:
Camera module provided by the present invention, the window edge of the support of fixed lens has light shield layer, thereby can pass through described light shield layer, avoid light to be entered after camera module by sensitive chip imaging by the window edge of support reflection, cause in the image of shooting and occur veiling glare phenomenon.
Brief description of the drawings
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of existing camera module;
The structural representation of the camera module that Fig. 2 provides for one embodiment of the present of invention.
Embodiment
As described in background, camera module is in the time of photographic light sources, and light can form reflection at the window edge of support, and the light after reflection can incide the photosurface imaging of sensitive chip, as shown in Figure 1, thereby occurs veiling glare phenomenon in the image that makes to take.
Based on this, the invention provides a kind of camera module, the problems referred to above that exist to overcome prior art, comprise the support of camera lens, fixed lens, the sensitive chip that is positioned at camera lens bottom and the circuit board being electrically connected with described sensitive chip, wherein, the window edge of described support has light shield layer, to stop that light is entered described camera module by the reflection of the window edge of described support.
Camera module provided by the present invention, the window edge of the support of fixed lens has light shield layer, thereby can pass through described light shield layer, avoid light to be entered after camera module by sensitive chip imaging by the window edge of support reflection, cause in the image of shooting and occur veiling glare phenomenon.
Be more than core concept of the present invention, for above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, the specific embodiment of the present invention be described in detail.
A lot of details are set forth in the following description so that fully understand the present invention, but the present invention can also adopt other to be different from alternate manner described here and implement, those skilled in the art can do similar popularization without prejudice to intension of the present invention in the situation that, and therefore the present invention is not subject to the restriction of following public specific embodiment.
Secondly, the present invention is described in detail in conjunction with schematic diagram, in the time that the embodiment of the present invention is described in detail in detail; for ease of explanation; represent that the profile of device architecture can disobey general ratio and do local amplification, and described schematic diagram is example, it should not limit the scope of protection of the invention at this.In addition in actual fabrication, should comprise, the three-dimensional space of length, width and the degree of depth.
One embodiment of the present of invention provide a kind of camera module, its structure as shown in Figure 2, comprise camera lens 20, accommodate and the support 21 of fixed lens 20, the circuit board 23 that is positioned at the sensitive chip 22 of camera lens 20 bottoms and is electrically connected with described sensitive chip 22, wherein, the window edge of the support 21 of fixing described camera lens 20 has light shield layer 24.
Because the window edge of support 21 has light shield layer 24, therefore, camera module is in the time taking intense light source, the light that incides support 21 window edges can be stopped by light shield layer 24, thereby avoid light to be entered after sensitive chip 22 imagings by support 21 window edge reflections, formed the veiling glare in photographic images.
Wherein, light shield layer is light-absorbing coating, is preferably black light-absorbing material.
The camera module that the present embodiment provides, the window edge of the support of fixed lens has light shield layer, thereby can pass through described light shield layer, avoid light to be entered after camera module by sensitive chip imaging by the window edge of support reflection, cause in the image of shooting and occur veiling glare phenomenon.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiment, General Principle as defined herein can, in the situation that not departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
