Fig. 2 is another structural representation of camera head provided in an embodiment of the present invention；
Fig. 3 is a kind of flow chart of the manufacture method of camera head provided in an embodiment of the present invention.
Specific embodiment
Further to illustrate the present invention to reach technological means and effect that predetermined purpose is taken, below
With reference to accompanying drawing and preferred embodiment, the present invention is described in detail as after.By specific embodiment
Illustrate, the present invention should more be deepened to reach technological means that predetermined purpose taken and effect
Enter and specifically understand, but appended diagram is only to provide reference and purposes of discussion, not for this hair
It is bright to be any limitation as.
As shown in figure 1, embodiments of the invention provide a kind of camera head, including：
First lens 1, light guide section 2, the second lens 3, imaging section 4；The optical axis of the first lens 1 and
The optical axis of two lens 2 is parallel to each other but not conllinear；Light from subject T passes through the first 1 one-tenth of lens
It is directional light；The directional light is incident to the second lens 3 to form converged light by light guide section 2, described
Converged light is imaged from after the injection of the second lens 3 in imaging section 4.
Camera head provided in an embodiment of the present invention, by the first lens 1 by the light from subject T
Become directional light, the directional light is incident to the second lens 3 to form converged light by light guide section 2, institute
Converged light is stated to be imaged in imaging section 4 from after the injection of the second lens 3.Due to the optical axis of the first lens 1 and
The optical axis of two lens 3 is parallel to each other but not conllinear, and realizes that light path is connected by light guide section 2, the first lens
1 just can be separately positioned with the second lens 3 and follow-up optical device, so as to reduce camera head along light
The size in road direction, effectively reduces the thickness of camera head, substantially increases Consumer's Experience.
Optionally, light guide section 2 can be conducted to second saturating the light of the outgoing of the first lens 1 for any
Device of mirror 3, such as optical fiber or fiber waveguide etc..Due to the optical axis and second lens 3 of the first lens 1
Optical axis is parallel to each other but not conllinear, and light guide section 2 needs light is certain along being carried out perpendicular to the direction of optical axis
Translation, therefore, the length and riding position of light guide section 2 are required for that the translation can be realized.It is optional
, the first lens 1 and the second lens 3 can be convex lens.
Further, in order that light can carry out Lossless transport in light guide section 2, it is preferred that light guide section
2 refractive index and riding position may be configured to make the light transmitted in light guide section 2 to be totally reflected.
Specifically, as shown in Fig. 2 imaging section 4 may include drive module 41 and image-forming module 42；
Image-forming module 42 is arranged in drive module 41, adjusts saturating with second under the driving of drive module 41
The distance of mirror 3, to realize focusing.Optionally, drive module 41 is specifically as follows voice coil motor etc..
Optionally, image-forming module 42 may include photosensitive sensor 421 and be arranged on photosensitive sensor 421
With the 3rd lens 422 between the second lens 3.Light from the outgoing of the second lens 3 is by the 3rd lens 422
After be incident to photosensitive sensor 421, on photosensitive sensor 421 be imaged.
Certainly, the light on photosensitive sensor 421 is irradiated to, its focal plane is not necessarily just by photosensitive sensing
Device 421 is captured, and this is accomplished by voice coil motor and carries out automatic focusing.According to automatic focusing principle：Work as sense
After optical sensor receives the image of most original, these view data can be taken as firsthand information to be sent to
In GPU (Graphics Processing Unit, image processor), now GPU will be to original number
According to being analyzed, the density variation in check image between adjacent pixels.If the focusing of original image is
Inaccurate, then the picture element density for adjoining will be sufficiently close to.GPU can be using corresponding algorithm to this
A little pixels are adjusted, and drive image-forming module 42 to move by by drive module 41, realize auto-focusing.
Specifically, voice coil motor mainly includes coil, group of magnets and shell fragment, coil is solid by upper and lower two shell fragments
It is scheduled in group of magnets, when to coil electricity, coil can produce magnetic field, and coil magnetic field and group of magnets are mutual
Effect, coil can produce displacement, and be locked in just moving together in coil, and when power is off, coil is in bullet
Returned under piece elastic force, be so achieved that automatic focusing function.
Accordingly, the present invention also provides a kind of mobile terminal, and above-mentioned implementation is provided with the mobile terminal
Any one camera head that example is provided, therefore corresponding technique effect can be also realized, have been carried out above
Describe in detail, here is omitted.
Accordingly, as shown in figure 3, the present invention also provides a kind of system of the camera head in previous embodiment
Method is made, including：
S11, manufactures the first lens, light guide section, the second lens and imaging section respectively；
S12, by first lens, the light guide section, second lens and the imaging section difference
Set on mobile terminals, the optical axis of first lens it is parallel to each other with the optical axis of second lens but
It is not conllinear.
The manufacture method of camera head provided in an embodiment of the present invention, manufactures the first lens, described leads respectively
Light portion, the second lens and imaging section, by first lens, the light guide section, second lens and
The imaging section is separately positioned on mobile terminal.Due to the optical axis and the optical axis of the second lens of the first lens
It is parallel to each other but not conllinear, and realize that light path is connected by light guide section, the first lens just can be with the second lens
And follow-up optical device is separately positioned, so as to reduce size of the camera head along optical path direction, effectively subtracts
The small thickness of camera head, substantially increases Consumer's Experience.
Although being example purpose, the preferred embodiments of the present invention, those skilled in the art are had been disclosed for
To recognize that various improvement, increase and substitution are also possible, therefore, the scope of the present invention should not be limited
In above-described embodiment.
