Embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the specific embodiment of the invention and
Technical solution of the present invention is clearly and completely described corresponding accompanying drawing.Obviously, described embodiment is only the present invention one
Section Example, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not doing
Go out under the premise of creative work the every other embodiment obtained, belong to the scope of protection of the invention.
Fig. 1 shows the flow chart of image capture method according to an embodiment of the invention, as shown in figure 1, the image capture method bag
Include：
Step 120, the first image is obtained, the first image is to carry out imaging acquisition to the scene in default first angle of visual field
Image information；
Step 140, the second image is obtained, the second image is to carry out imaging acquisition to the scene in default second angle of visual field

Three reflectings surface 303；
First reflecting surface 301 is used to block the light from external incident, makes the extraneous light in second angle of visual field incident
To the second reflecting surface 302 and the 3rd reflecting surface 303；
Second reflecting surface 302 and the 3rd reflecting surface 303 are set towards the first reflecting surface 301, for by incidence exterior light
Line reflection makes the first reflecting surface 301 to incident after the second reflecting surface 302 and the reflection of the 3rd reflecting surface 303 to the first reflecting surface 301
Light reflected.
First reflecting surface 301 can be arranged on lens barrel, for example, it is anti-to plate reflectance coating formation first in lens barrel front end face
Penetrate face；First reflecting surface can also be used as individual components.The length of first reflecting surface 301 can be set accordingly, shield portions
Outside light, it is the scene in second angle of visual field to make the outside light entered.
Second reflecting surface 302 and the 3rd reflecting surface 303 can be in the protective glass inner surface plating reflectance coating realities of the second camera lens
Existing, the second reflecting surface 302 and the 3rd reflecting surface 303 can have certain inclination angle, can also be vertically arranged.
Optionally, the second reflecting surface 302 and the 3rd reflecting surface 303 are symmetrical with the axis X of the second camera lens 102 and set, and the
The axis X of two camera lenses 102 passes through the center of the first reflecting surface 301.This structural being symmetrical arranged can ensure to be imaged
Symmetry.
Fig. 5 shows that mobile terminal includes the front view of the first camera lens 101 and the second camera lens 102.As shown in figure 5, first
The camera lens 102 of camera lens 101 and second is vertically arranged, and the first camera lens 101 and the second camera lens 102 can be positioned at the backs of mobile terminal
Centre position, or the side at mobile terminal back.Certainly, the first camera lens 101 and the second camera lens 102 can also be arranged in parallel,
And it is located at left side, right side or the centre position at mobile terminal back accordingly.It is appreciated that the first camera lens 101 and second
Camera lens 102 can not only be installed on mobile terminal, can also be installed on the terminals such as video camera, will not enumerate herein.Need
, it is noted that the installation site and set-up mode of the first camera lens 101 and the second camera lens 102 can be adjusted reasonably.
Generally, the first camera lens 101 using conventional camera lens when, its first angle of visual field can be 0 to 88 °, 0 to 86 ° or its
Angle similar in him, pixel can be 13mega pixels (mega pixel).Herein, the scope and pixel of first angle of visual field
Can accordingly it select.Second angle of visual field of the second camera lens 102 can be 80 ° to 120 °, and pixel can be 7mega pixels.
Herein, the angle of second angle of visual field corresponding can select to pixel, and the present embodiment is not limited only to data above.
In second camera lens, the light for the scene angle of visual field that the second reflecting surface 302 and the 3rd reflecting surface 303 receive 80 ° to 120 ° passes through
Secondary reflection (the first reflecting surface 301 is reflexed to by the second reflecting surface 302 and the 3rd reflecting surface 303, then by the first reflecting surface
301 reflections are imaged) after, the angle that can make arrival mobile terminal interior len is only 44 ° to 76 °, comparatively, compares appearance
Easily realize the design of lens component in mobile terminal.When being ultimately imaged, the image that the first camera lens and the second camera lens obtain is synthesized
The angle of visual field is can obtain afterwards as 0 ° to 120 °, and pixel is 20mega high quality wide angle picture.
Thus, imaged viewing angle can be expanded by two angles of visual field of two or more；In imaging process, small angle scene
(i.e. scene in first angle of visual field) does not repeat to take Image space, ensure that the enough information integrities of peripheral vision, realizes
The lifting of picture whole pixel.Meanwhile in imaging process, because the aperture that need not reduce camera lens can be implemented as the big of picture
Visual angle, overcome conventional art can only reduce camera lens aperture can just be implemented as picture big visual angle understanding.
Fig. 6 shows the schematic diagram being combined after mobile terminal imaging.As shown in fig. 6, the first camera lens 101 is obtained
After the image that image and the second camera lens 102 obtain is combined, it can obtain whole comprising first angle of visual field and second angle of visual field
Body image.Herein, mobile terminal can carry out splicing by processor to two images, wherein, processor can select
Appropriate algorithm is selected to splice two images.
Fig. 7 shows the schematic diagram during mobile terminal imaging of another embodiment of the present invention.As shown in fig. 7, mobile terminal
Including camera lens 501 could be arranged to one；
Mobile terminal can also include the mobile sliding block 502 set towards camera lens 501, for being located in mobile sliding block 502
During first position, camera lens 501 is imaged the scene in default first angle of visual field, and be located at second in mobile sliding block
When putting, camera lens is set to be imaged the scene in default second angle of visual field.
