Fig. 1 is the structural representation of a kind of Double-camera device disclosed in the utility model embodiment；
Fig. 2 is the structural representation of another kind of Double-camera device disclosed in the utility model embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, to the technology in the utility model embodiment
Scheme is clearly and completely described, it is clear that described embodiment is only the utility model one
Divide embodiment rather than whole embodiments.Based on the embodiment in the utility model, this area is common
The every other embodiment that technical staff is obtained under not making creative work premise, broadly falls into this
The scope of utility model protection.
The utility model embodiment discloses the terminal device of a kind of Double-camera device and application thereof, with reality
Existing dual camera not only can realize wide viewing angle video calling but also can shoot the photo of relatively high image quality.
See Fig. 1, the structural representation of a kind of Double-camera device that the utility model embodiment provides, bag
Include: the first camera 11, second camera 12, display 13, CPU (Central Processing Unit,
Central processing unit) 14 and GPU (Graphics Processing Unit, graphic process unit) 15；
Wherein,
First camera 11 and second camera 12 are arranged on terminal device homonymy, the first camera 11 and
A camera in two cameras 12 is ultra wide-angle imaging head, and another camera is that horizontal field of view angle exists
The camera of 70 degree of-90 degree, i.e. common camera.
It should be noted that ultra wide-angle imaging head is the shooting up to 180 degree of a kind of horizontal field of view angular region
Head, therefore can receive the scenery at bigger visual angle, uses this camera can provide when video calling
Preferably Consumer's Experience, allows partner see the scene information around more multi-user, when for many people
During video calling the most convenient.
The horizontal field of view angle of common camera, at 70 degree of-90 degree, has good photographic effect, it is possible to shooting
Go out the photo of relatively high image quality.
Camera switching command can be converted into passage switching command by CPU14.
GPU15 includes: the first IMAQ port, the second IMAQ port, control signal collection terminal
Mouth and output end of image mouth, described first IMAQ port and described second IMAQ port can be cut
Change and be connected to described control signal collection port；
The first IMAQ port of GPU15 connects the output port of the first camera 11, the of GPU15
Two IMAQ ports connect the output port of second camera 12, and the output end of image mouth of GPU15 connects
The input port of display 13, the control signal that the control signal of GPU15 gathers port connection CPU14 is defeated
Go out port.
The operation principle of Double-camera device is:
CPU14 judges the camera needing to start according to the enabled instruction received, and by this enabled instruction
Be converted into correspondence camera link order output to GPU15, GPU15 receive this camera connect refer to
Opening the IMAQ port of correspondence after order, (the first camera 11 or the second is taken the photograph to connect corresponding camera
Picture 12), and start to receive the view data collected of this camera output, GPU15 is to this image
Data export after carrying out quality optimization process to display 13 and show so that user is able to carry out taking pictures or
Vision operation.
When needs carry out camera switching, the camera switching command received is converted into logical by CPU14
Road switching command, and export and receive passage switching command rear cutout to GPU15, GPU15 and change corresponding figure
As gathering port and being attached with the camera after switching, the camera output after having connected gathers
To view data complete camera switching.
In summary it can be seen, by the first IMAQ port and the control of the second IMAQ port,
The mutual switching of the output of ultra wide-angle imaging head and common camera can be realized, due to ultra wide-angle imaging head
Can receive the scenery at bigger visual angle, it is possible to achieve wide viewing angle video calling, common camera can shoot
Going out the photo of relatively high image quality, therefore, user can switch the camera of the different angle of visual field according to self-demand,
To meet the use demand in different scenes.
It should be noted that the feeder ear of the feeder ear of the first camera 11 and second camera 12 is the most only
Vertical.
Wherein, the first camera 11 and second camera 12 can be arranged on the front panel of terminal device
Or be arranged on the rear board of terminal device.
For convenience of video and auto heterodyne, the first camera 11 and second camera 12 can be arranged at terminal
The upper side frame of equipment, naturally it is also possible to as required two cameras are arranged at the side of terminal device
Frame.
Two cameras arrange position concrete according to being actually needed depending on, only need to ensure two camera positions
Homonymy in terminal device.
Owing to the Edge Distance between two cameras can affect the angle of the cone, therefore, for improving user
Experience, within the Edge Distance between two cameras can being set to 10mm so that user feel not
Change to the cone.
Input it is understood that the camera switching command that CPU14 receives can be user, example
As, a switching push button is set on the terminal device, user realizes ultra-wide angle by clicking on this switching push button
Switching between camera and common camera；Can also is that CPU14 is according to the attitude residing for terminal device certainly
Row judgement obtains.
Therefore, for optimizing above-described embodiment further, seeing Fig. 2, another embodiment of the utility model provides
The structural representation of a kind of Double-camera device, on the basis of embodiment illustrated in fig. 1, also include: weight
Force snesor 16；
The signal output port of gravity sensor 16 gathers port with the control signal of CPU14 and is connected, signal
End that output port output measures according to the Gravity changer of terminal device, as camera switching command
End equipment angle of inclination with respect to the horizontal plane.
It should be noted that the acceleration caused due to gravity by gravity sensor 16 measuring terminals equipment,
This terminal device angle of inclination with respect to the horizontal plane can be calculated.
Concrete, terminal device angle of inclination with respect to the horizontal plane is exported extremely by gravity sensor 16
After CPU14, CPU14, by the comparative result at this angle of inclination Yu predetermined angle, determines and is currently needed for connecting
Camera.
In summary it can be seen, the Double-camera device that the utility model provides both can be real by switching push button
Existing manual switching, can realize automatically switching by gravity sensor 16 again.
Corresponding with above-mentioned Double-camera device, the utility model additionally provides a kind of terminal device, and this is eventually
End equipment includes above-mentioned Double-camera device.
Wherein, in terminal device, the operation principle of Double-camera device is with above-mentioned, and here is omitted.
