Abstract
Technical scheme includes a kind of system and method based on the more Application share cameras of Android, for realizing：Obtain the data address of camera device in android system；Create multiple virtualization camera devices to be shared and associated with the data address that the address acquisition module obtains, each data address for virtualizing camera device possesses unique mark；The video data of camera device is obtained by data address using virtualization camera device, and is sent to corresponding application program, and, use the function of camera device.Beneficial effects of the present invention are：In android system multiple application programs can be made to use camera device and camera function not the strategy switching by camera device.
Description
Technical field
The present invention relates to a kind of system and method based on the more Application share cameras of Android, belong to computer realm.
Background technology
In some special application scenarios.Such as backstage is being recorded a video always, at this moment camera can videoed to apply and account for always
Have, others application can not open camera again.If other application will so must be first occupancy camera using camera
Same application is exited.
So done without good solution, some schemes in the industry at present：
Scheme 1：During using opening camera, if camera is occupied, that just forces camera to give last opening
The application of camera.Substantially it is not shared, simply have modified the strategy that camera uses.
Scheme 2：Do not change the occupancy of camera, but change the window of camera preview.Which application wants preview to image
Which application camera preview data is just switched to by head image.
Prior art (patent No. 2016105494670) discloses what is shared based on Android intelligent back vision mirrors camera
System and method, its system include application layer and ccf layer, and the application layer has at least two answering using camera resource
Use program unit；Wherein, camera service layer, camera client and camera hardware adaptation are provided with the ccf layer
Layer, for after the client that the camera has created before finding, by the camera service layer set the preview window to
The camera client, and the preview window is passed to the camera adaptation layer by the camera client, and by the camera
Adaptation layer is filled the preview window progress preview and shown.
Applicant think only be merely camera picture display strategy adjustment.Do not realize really shared.
The content of the invention
In view of the shortcomings of the prior art, technical scheme is provided one kind and taken the photograph based on the more Application shares of Android
As the system and method for head, another camera is fictionalized in virtual hardware, can completely support Android cameras
Institute it is functional, including preview is taken pictures, video recording etc., and allows multiple applications preview camera picture simultaneously, is realized real
Shared camera.
Technical scheme includes a kind of system based on the more Application share cameras of Android, it is characterised in that
The system includes：Address acquisition module, for obtaining the data address of camera device in android system；Virtual photographing module,
Shared and associated with the data address that the address acquisition module obtains for creating multiple virtualization camera devices, each
The data address of virtualization camera device possesses unique mark；Image Sharing module, for being passed through using virtualization camera device
Data address obtains the video data of camera device, and sends to corresponding application program.
According to the system based on the more Application share cameras of Android, address acquisition module therein also includes：
Need to use the application program of camera device used in user in system for identifying and the number of camera device can be used, will take the photograph
Identifier and application program identification add different data queues as corresponding to device, and provide editing interface to using journey
Sequence interacts with camera device carries out customized control, wherein control includes the association for releasing and establishing different pieces of information queue.
According to the system based on the more Application share cameras of Android, virtual photographing module therein also includes：
For multiple application program identification codes of camera device needed for acquisition in real time, created for each application program virtual corresponding to corresponding to
Camera device, each virtual camera device have unique mark.
According to the system based on the more Application share cameras of Android, virtual photographing module therein also includes：
For creating main virtual video camera device according to the data address of acquired camera system, further, virtually taken the photograph by master
As device shares the data address of camera system to other multiple virtual video camera devices.
According to the system based on the more Application share cameras of Android, virtual photographing module therein also includes：
Multiple virtual video camera devices therein are located at the hardware abstraction layer of android system.
According to the system based on the more Application share cameras of Android, Image Sharing module therein also includes：
Sent for the video stream data gathered by virtual camera device acquisition cam device, and by video stream data to corresponding
Application program, and, use the function of camera device.
Technical scheme also includes being based on the more Application shares shootings of Android according to one kind of above-mentioned any system
The method of head, it is characterised in that this method includes：Obtain the data address of camera device in android system；Create multiple void
Planization camera device is shared and associated with the data address that the address acquisition module obtains, and each virtualizes camera device
Data address possess unique mark；The video data of camera device is obtained by data address using virtualization camera device,
And send to corresponding application program,.
Beneficial effects of the present invention are：It is able to can make not the strategy switching by camera device in android system
Multiple application programs use camera device and camera function.
Brief description of the drawings
Fig. 1 show the general structure block diagram according to embodiment of the present invention；
