But when the camera module of dual camera uses a telephoto lens and a wide-angle/common lens, can exist
Problems with：
First, Material Cost lifting, because using two camera lenses, its cost is the two of traditional single camera module price
Times；
Second, the lifting of hardware circuit design complexity, two sensitive chips are used for example, working as, such as cmos image sensing
, it is necessary to increasingly complex hardware circuit, such as power supply, data-interface during the scheme of device；
3rd, higher requirement is proposed to application processor (AP), considers the mobile phone simultaneous with preposition camera function
At least there are three cameras (for example, rearmounted double camera modules and preposition single camera module), its primary processor is also required to
At least three camera data-interfaces (generally move Industry Processor MIPI interfaces), and this causes only part high-end processors
It could support, further improve double costs for taking the photograph mobile phone；
4th, higher requirement is it is also proposed to software and algorithm, system needs to provide extra webcam driver program
Switching/while operating mechanism with driver, additionally, due to dual camera it is difficult to accomplish on hardware time synchronized and shooting/
Exposure parameter matches the staking-out work, it is necessary to extra, and the scene process effect to quickly moving is bad.

Primary optic axis be not orthogonal to the imaging surface, the imaging surface includes the first imaging region and the second imaging region, from
Extraneous the first incident light is imaged on first imaging region by first lens group 110, from extraneous incidence
Second light is imaged on second imaging region by second lens group 120；With, the first leaded light device group 140, use
In guiding, first light is incided in first lens group 110 and guiding going out from what first lens group 110 was emitted
Photoimaging is penetrated on first imaging region.
In the camera module 100 according to the embodiment of the present application, subject is imaged on sense by first lens group 110
On first imaging region of optical chip 130, and the subject is imaged on same sensitive chip by second lens group 120
On 130 the second imaging region.Therefore, single sensitive chip 130 is used only just according to the camera module 100 of the embodiment of the present application

Please the camera module 100 of embodiment need not use specific lens group and sensitive chip, therefore being capable of compatible main flow list shooting
The scheme of hardware/system software of head, significantly reduce the cost of whole system.
In addition, when sensitive chip is cmos image sensor, because cmos image sensor has Rolling shutter in itself
Characteristic, double time synchronization errors for taking the photograph image can make it that within 0.1ms, it is more preferable to the scene effect quickly moved.
Below, the first leaded light device group 140 will be specifically described.
Fig. 2 is the schematic diagram according to an example of the camera module of the embodiment of the present application.As shown in Fig. 2 camera module
Including the first lens group 210, the second lens group 220 and sensitive chip 230, and the first leaded light device group includes the first speculum
240 and second speculum 250.When being imaged using the camera module to subject, incident ray is incident from Fig. 2 left side, warp
First reflection light is formed after the reflection of first speculum 240, the first reflection light is focused on by first lens group 210
The emergent light is formed, the emergent light forms second of reflected light, second secondary reflection via second speculum 250
Photoimaging the sensitive chip 230 the first imaging region, i.e. in Fig. 2 in the upper half area of sensitive chip 230.
Because the first speculum 240 and the second speculum 250 carry out level crossing reflection to light, light is in the first reflection
Incidence angle on the speculum 250 of mirror 240 and second is respectively equal to the angle of emergence, therefore, based on this, can calculate the first speculum
240th, the second speculum 250 and the first lens group 210 are each relative to the angle of imaging surface.It is assumed that the first speculum 240 with
The angle of imaging surface is α 1, then the angle of the second speculum 250 and imaging surface also be α 1, and the first lens group 210 and into
The angle of image surface is 90 ° of+2* α 1.
Also, in the camera module according to the embodiment of the present application, in order that obtaining the quilt formed on the first imaging region
Subject image and the subject image formed on the second imaging region are not interfere with each other, and the second speculum could be arranged to first
Imaging region and the second imaging region are optically separated.That is, one end of the second speculum can be located at first
The intersection of imaging region and the second imaging region, so that being directly imaged by the second lens group on the second imaging region
Light and the light that is imaged by the first lens group on the first imaging region it is separated from one another.
Therefore, in above-mentioned camera module, the first leaded light device group includes：First speculum, with the imaging table
Face is set into first angle α 1；With the second speculum, first is arranged on into the first angle α 1 with the imaging surface
Put, and be located at first imaging region and second imaging region in one end of the second speculum described in the first position
Intersection, first lens group between first speculum and second speculum, the primary optic axis with
The imaging surface is set into second angle α 2, α 2=90 °+2* α 1.
Also, in above-mentioned camera module, first light forms first reflection light via first speculum,
The first reflection light focuses on to form the emergent light by first lens group, and the emergent light is anti-via described second
Penetrate mirror and form second of reflected light, second of reflected light is imaged on first imaging region.
Here, it will be understood by those skilled in the art that in the camera module according to the embodiment of the present application, the first speculum
It can be set within the specific limits relative to the angle of imaging surface with the second speculum, to cause subject to pass through the first lens
Group is imaged in the first imaging region of sensitive chip.
Fig. 3 is the schematic diagram according to an imaging example of the camera module of the embodiment of the present application.As shown in figure 3, this Shen
Please the essence of optical imagery of embodiment camera module be considered as to be (anti-from second by the mirror sections of the second speculum
The region penetrated between an end points C to another end points D for mirror) by the first imaging region CT of sensitive chip (for example, from photosensitive core
Region between the central point C to upper extreme point T of piece) empty imaging plane CT ' is projected as, so that going out by the first lens group
Light is penetrated to be imaged on the empty imaging plane CT '.Wherein, point T be sensitive chip up contour point, and point T ' be T on minute surface
Symmetric points.Also, it is imaged on by the emergent light of the second lens group on the second imaging region of sensitive chip bottom.
Here, when first angle α 1 is 45 degree, empty imaging plane CT ' is perpendicular to the first imaging region CT, so as to hang down
Directly in sensitive chip is divided into the first imaging region and the second imaging region on the direction of sensitive chip.Those skilled in the art
It is appreciated that the point C of the first imaging region of division and the second imaging region can be located at the height center of sensitive chip, to cause
CMOS can be imaged respectively in the imaging region of formed objects for the light by two lens groups, so as to obtain phase
With two images of size.Alternatively, for other different designs, point C can also be located elsewhere, to obtain different chis
Very little image pair.
Although the examples of first angle α 1 are 45 degree by Fig. 3, first angle α 1 can also be in centered on 45 degree
In preset range.If the angle sets too small, focusing on the emergent light to be formed by the first lens group may be by photosensitive
The stop of first imaging region of chip, so as to influence the image quality on the first imaging region；And if the angle is set
It is too big, then the second speculum, which is difficult to that the emergent light to be formed will be focused on by the first lens group, all reflexes to the first imaging region
On, it can also influence the image quality on the first imaging region.
Therefore, in above-mentioned camera module, the first angle α 1 can change between 15 degree to 75 degree, it is preferable that
Change between 30 degree to 60 degree.It is further preferable that in above-mentioned camera module, the first angle α 1 can be equal to 45 degree.
In addition, order point M for the photocentre O1 and point T ' of the first lens group (camera lens 1) line O1T ' (that is, the first lens group
The left margin of visual field) with the second speculum CD intersection point, and f1 is the focal length of the first lens group.In the second speculum and imaging
In the case that first angle α 1 between surface is equal to 45 degree, in order that the emergent light for obtaining the first lens group all reflexes to first
On imaging region, and it is unlikely to leak into outside the first imaging region, as shown in figure 3, the focal length of the first lens group can be caused
F1 is more than or equal to the length CT of the first imaging region.In other words, the focal length f1 of the first lens group minimum value is the first one-tenth
As the length CT in region.Therefore, the focal length f1 of first lens group can be bigger numerical value, i.e., by the first lens group selection
For in/telephoto lens.Certainly, when selecting the focal length f1 of the first lens group, if its numerical value is excessive, camera module is in height side
Size will also become big on to (that is, the above-below direction in Fig. 3), and focal length is longer, and the cost of camera lens can also greatly improve.Cause
This, the focal length f1 of first lens group can take into account above two factor and carry out comprehensive selection.
Meanwhile in order that the second speculum the emergent light by the first lens group can all be reflected, without
As for intercepting, as shown in figure 3, the length CD of the second speculum is also required to be more than or equal to length CM.Above is in CMOS
Sectional view dimension on discuss the length of the second speculum, it may occur to persons skilled in the art that, in CMOS top view
Angle need also exist for consider speculum width.
Therefore, in above-mentioned camera module, the focal length of first lens group is more than or equal to first imaging region
Length.Also, in above-mentioned camera module, the focal length of the second size of second speculum and first lens group and
The size of first imaging region is associated.
In addition, the visual angle of the first lens group is actually what is determined by the focal length of the first lens group, when the first lens group
When focal length f1 increases, the visual angle of the first lens group correspondingly reduces, and vice versa.In theory, as the focal length f1 of the first lens group
Equal to the first imaging region length CT when, the focal length of the first lens group is in limit minimum value；And its visual angle is in the limit most
Big value, is 2*arctan (1/2).
Certainly, if the visual angle of the first lens group is more than view angle theta 1 as shown in Figure 3, by being focused on after the first lens group
Light all can not be imaged on empty imaging plane CT ' so that only a part for subject is imaged on the first imaging region,
At this moment need to select bigger cmos device.Certainly, if necessarily realizing complete imaging, the visual angle of the first lens group also may be used
To be set greater than the view angle theta 1 shown in Fig. 3, and keep the size constancy of cmos device.
On the other hand, as shown in figure 3, the second lens group (camera lens 2) can be simply set as without leaded light device group
Guiding, and be directly imaged on imaging surface.In other words, the light from subject is directly entered the second lens group, and
And it is projected directly at after being focused on via the second lens group on the second imaging region of sensitive chip.
Therefore, in above-mentioned camera module, the second optical axis of the second lens group is set perpendicular to the imaging surface, described
Second light is directly imaged on second imaging region by second lens group.
For the second lens group, because in the absence of lens group by the situation of reflective mirror blocks, for the second lens group
Focal length f2 be not particularly limited.In order to obtain camera module chi thinner on thickness direction (that is, the left and right directions in Fig. 3)
Very little, the focal length f2 of second lens group can be smaller numerical value, i.e., be wide-angle/common lens by the second lens group selection.
Also, it is similar with the view angle theta 1 of the first lens group, show that the emergent light focused on by the second lens group projects completely in Fig. 3
Situation on second imaging region, wherein, the optical axis of the second lens group and the intersection point of imaging surface are located at the second imaging region
Center, and the view angle theta 2 of the second lens group and focal length f2 make it possible to intactly be imaged on the second imaging region.However, such as
Fruit can allow imperfect imaging, and the view angle theta 2 of the second lens group is not also limited.
Fig. 4 is the schematic diagram according to another imaging example of the camera module of the embodiment of the present application.Fig. 4 and Fig. 3 difference
It is, in figure 3, the intersection point of primary optic axis and imaging surface is located at the center of the second imaging region, so as to pass through the second lens
Second light of group is only imaged on the second imaging region.And in Fig. 4, the intersection point of primary optic axis and imaging surface is positioned at described
On imaging surface on the intersection of the first imaging region and the second imaging region, for example, positioned at imaging surface along its length
On center line, i.e. the center of the first imaging region and the second imaging region entirety so that pass through the second of the second lens group
Light can be not only on the second imaging region, and is imaged on the first imaging region.That is, in above-mentioned camera module
In, the intersection point of second optical axis and the imaging surface is located at the friendship of first imaging region and second imaging region
At boundary.So so that in the second speculum, in the first position shown in Fig. 3, (one end of second speculum is positioned at described the
The intersection of one imaging region and second imaging region) when, it will stop the second image formation by rays in first imaging area
On domain, and make it that it is only imaged on the second region, i.e., some visual field is blocked.But if the second speculum
It can be moved away from the first position, and no longer stop the second image formation by rays when on first imaging region, second is anti-
Bigger areas imaging can then be obtained by penetrating mirror, so as to obtain larger sized image.
Correspondingly, the first leaded light device group further comprises the driving part for driving the second speculum to change position,
So as to which the second speculum to be shifted out through to projection scope of the emergent ray of the second lens group in the imaging surface of sensitive chip.Example
Such as, as shown in Fig. 2 by the driving of driving part, the second speculum 250 is moved to such as dotted portion from initial first position
250 ' shown in the second place (for example, this can by elder generation to upper left it is mobile, using any be again that axle is rotated come reality
It is existing).On the one hand, the second speculum 250 ' after movement no longer forms any stop to the light being emitted from the second lens group, makes
It can be intactly imaged on first imaging region, rather than only half is imaged；On the other hand, the second speculum
250 ' but completely shielding from the first lens group outgoing light, it can not be imaged on first imaging region so that
Obtain and single camera module is used as according to the camera module of the embodiment of the present application, obtain larger sized image.
That is, in above-mentioned camera module, the first leaded light device group further comprises driving part, for driving
Move second speculum and be moved to the second place from the first position, second speculum stops in the second place
First light, without stopping second image formation by rays on first imaging region.
Therefore, have what is switched between single camera module and double camera modules according to the camera module of the embodiment of the present application
Handover mechanism.When not needing dual camera, only subject can be imaged by the first lens group, it is photosensitive so as to make full use of
The pixel of chip, improve image quality；On the other hand, again can be right respectively by two lens groups when needing dual camera
Subject is imaged, it is achieved thereby that the flexibly camera module dynamic structure of purpose.
As described above, traditionally, in the manufacturing process of camera module, for zoom lens, camera lens
Focal length significantly limit camera module in focal length direction, the i.e. size on the direction of the imaging surface of sensitive chip.
Therefore, according in the camera module of the embodiment of the present application, sensitive chip is not orthogonal to by the optical axis of the first lens group
Imaging surface, the thickness of camera module in the direction of the optical axis can be reduced.
As shown in Figures 2 and 3, in the case where first angle is 45 degree, the optical axis direction of the first lens group parallel into
The direction of image surface, therefore, the thickness of camera module are substantially determined by the focal length of the second lens group.So for maximum journey
Degree ground reduces the thickness of camera module, can be by the lens group with smaller focal length, for example, wide-angle/common lens are as second
Lens group.
Therefore, in above-mentioned camera module, the focal length of first lens group can be more than Jiao of second lens group
Away from.
In double camera modules, for example, the first lens group can be equivalent 50mm or so telephoto lens, and the second lens
Group can be equivalent 17mm-28mm wide-angle/common lens.
Fig. 5 is the schematic diagram according to another example of the camera module of the embodiment of the present application.Camera module shown in Fig. 5 with
The difference of camera module shown in Fig. 2 is, with the first lens group similarly, the optical axis of the second lens group is also not orthogonal to photosensitive
