[0044] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0045] Figure 1 This is a schematic diagram illustrating the implementation of the method for sharing a camera in this application. Figure 1This method is applied to the primary application of cameras in electronic devices that require prolonged use. The method includes:

[0046] Step 101: Obtain image acquisition information from at least one second application process through the first application process, wherein the image acquisition information includes at least an image storage address;

[0047] Step 102: Establish a first image acquisition channel based on the image storage address of the first application process and the image storage address of the second application process;

[0048] Step 103: Based on the first image acquisition channel, send the first image acquisition request of the first application process and the second image acquisition request of the second application to the camera service layer, so that the camera service layer sends the image data acquired by the camera to the image storage area of ​​the first application process and the image storage area of ​​the second application process based on the first image acquisition request and the second image acquisition request.

[0049] In this application, the electronic device is an electronic device with an Android operating system and image acquisition capabilities, and the electronic device has at least one first application that needs to occupy the camera for an extended period of time, such as a security application or a video recording application. When the electronic device has at least one second application, the electronic device can obtain the image acquisition information of the at least one second application through the process of the first application. Here, the second application can be a video call application or a camera application, i.e., an application that does not occupy the camera for an extended period of time.

[0050] In this application, the first application process may have a camera sharing service. The electronic device can receive a first service call request sent by at least one second application process for the camera sharing service through the first application process. The first application process responds to the first service call request to establish a communication connection with the second application process through the camera sharing service interface of the camera sharing service.

[0051] In this application, the electronic device can collect image acquisition requests from at least one second application process in a cross-process manner through the camera sharing service interface in the first application process, wherein the image acquisition request may carry the image acquisition information.

[0052] Here, the image acquisition information includes, but is not limited to, the image storage address (Surface object) of the second application process and template data. The image storage address allows allocation of an image storage area for the second application process, and the template data determines the type of image acquisition request for the second application process. For example, the template data could be: TEMPLATE_PREVIEW (preview template) or TEMPLATE_STILL_CAPTURE (photo template). The preview template corresponds to a series of consecutive image acquisition requests, while the photo template corresponds to a single image acquisition request.

[0053] In this application, after the electronic device obtains image acquisition information from the second application process through the first application process, it can re-establish an image acquisition channel (referred to as the first image acquisition channel) based on the image storage address carried in the image acquisition information and the image storage address of the first application process. This releases the image acquisition channel (referred to as the second image acquisition channel) established between the first application process and the camera service layer. The second image acquisition channel is designed for operation only by the first application process. This is because the first application in the electronic device is in a state of long-term camera occupancy. When the second application does not access the camera, the second image acquisition channel established between the first application and the camera service layer is only for the use of the first application process. Other application processes cannot access the camera through this second image acquisition channel. Therefore, when the second application accesses the camera, it is necessary to re-establish an image acquisition channel through the first application process that allows multiple application processes to access the camera simultaneously. Thus, the first image acquisition channel enables multiple application processes to use the camera simultaneously.

[0054] In this application, after the electronic device establishes a first image acquisition channel that can be used by multiple application processes through the first application process, the first application process can also generate an image acquisition request (referred to as a second image acquisition request) for the second application process based on the image storage address and template data of the second application process. Then, the first application process sends the first image acquisition request of the first application process and the second image acquisition request of the second application process together to the camera service layer through the first image acquisition channel.

[0055] After receiving the first and second image capture requests, the camera service layer prioritizes the received requests according to the Android operating system's sorting method. Based on the sorting result, it retrieves a target image capture request (CaptureRequest) from the request queue (this could be from the first application or the second application) and sends it to the camera device. The camera service layer then requests an image storage area from the image buffer compositing service layer (SurfaceFlinger) based on the GraphicBufferProducer object carried in the CaptureRequest's Surface. Simultaneously, it establishes a mapping between the second application's image storage address and this image storage area, ensuring that the image storage area is mapped to the second application process. This allows the second application to obtain the image data captured by the camera from this image storage area.

[0056] The camera device retrieves the target image storage area (GraphicBuffer) corresponding to the target image storage address (Surface object) carried in the target image acquisition request, and then sends the currently acquired image data to the target image storage area (GraphicBuffer) through the camera device. Here, the target image storage area includes the image storage area corresponding to the image storage address of the first application process and the image storage area corresponding to the image storage address of the second application process. In this way, the second application can achieve camera sharing through the first application process without modifying the Android system's camera service and camera architecture.

[0057] Figure 2 This is a schematic diagram illustrating the method for sharing a camera in this application. Figure 2 ,like Figure 2 As shown, the system comprises five parts: a first application 21, a second application 22, a camera sharing service 23, a camera service 24, and an image buffering and compositing service 25. The first application 21, for example, is a security application (App) that requires long-term camera access. The second application 22 establishes a connection with the camera sharing service 23 within the first application 21 process via AIDL (Android Interface Definition Language). The process of the second application 22 sends an image storage address (Surface) and an image capture (CaptureRequest) template to the process of the first application 21. The process of the first application 21 creates an image capture request based on the parameters of the Surface and CaptureRequest template passed by the process of the second application 22.

[0058] (CaptureRequest), and send the CaptureRequest to the camera service 24.

[0059] (CameraService) The CameraService notifies the camera to render the image storage address object (Surface object) of the second application process 22.

[0060] The detailed technical process of this method includes:

[0061] 1) The process of the first application 21 obtains the camera manager through the service interface;

[0062] Here, after the first application process starts, it uses the standard Camera API V2 to access the camera through the Camera Framework.

[0063] 2) The process of the first application 21 opens the camera device through the camera manager;

[0064] 3) The first application 21's process creates an image acquisition channel;

[0065] Here, after the process of the first application 21 obtains the CameraDevice of the specified camera, it creates an image acquisition channel (Capture Session).

[0066] 4) The first application 21 sets the image storage address (Surface) A of the first application 21 process;

[0067] 5) The process of the first application 21 generates an image acquisition request A based on the image storage address A;

[0068] 6) The process of the first application 21 sends an image acquisition request A to the camera service 24;

[0069] Here, since the first application needs to occupy the camera for a long time, the camera service will continuously add the first application process's image capture request A (CaptureRequestA) to the camera service queue.

[0070] 7) Camera driver 26 retrieves an image acquisition request A from the request queue;

[0071] Here, the most recently entered image acquisition request is usually retrieved from the request queue, meaning the camera service uses a first-in, first-out (FIFO) strategy.

[0072] 8) The camera driver 26 drives the camera hardware 27 to fill the image data captured by the camera into the image storage area A corresponding to the image acquisition request A.

[0073] The above describes the specific process for using the camera only in the first application. The following section introduces the camera sharing process for the second application.

[0074] 9) The process of the second application 22 calls the camera sharing service 23 in the process of the first application 21 in a cross-process manner through the service interface.

[0075] Here, the service interface can be an AIDL interface. The camera sharing service 23 is started when the process of the first application 21 starts. When the process of the second application 22 opens the specified camera through the camera manager, if the camera opens successfully, it means that the camera is not occupied and can be used normally through the standard camera application interface of the Android system; if the camera fails to open, it means that the camera is occupied, and a connection is established with the camera sharing service (ShareCameraService) 23 of the first application 21 process through the AIDL interface.

[0076] 10) Camera sharing service 23 returns Binder parameters to the process of the second application 22;

[0077] 11) The process of the second application 22 sends image acquisition information to the camera sharing service 23 based on the Binder parameters.

[0078] Here, the image acquisition information includes at least image storage address B and image template data; specifically, image storage address B can be a Surface container, such as ImageReader, SurfaceView, SurfaceTexture, etc. Then, the serialized SurfaceB and image template data are encapsulated to obtain a serialized data packet, which is then sent to the camera service 23.

[0079] Here, the image template data can be, for example, a TEMPLATE_PREVIEW preview template or a TEMPLATE_STILL_CAPTURE photo template.

[0080] 12) The camera sharing service 23 deserializes the image storage address B sent by the second application 22 to obtain the image storage address B.

[0081] 13) The first application 21 recreates the image acquisition channel based on the image storage address A of the process of the first application 21 and the image storage address B of the process of the second application 22, while releasing the image acquisition channel originally created by the process of the first application 21.

[0082] Here, the image acquisition channel originally created by the first application process 21 could only be used for communication between the first application process 21 and the camera service. The newly created image acquisition channel can be used for communication between multiple application processes and the camera service simultaneously.

[0083] 14) The first application 21 process generates an image acquisition request B for the second application 22 process based on the image storage address B and the image template data of the second application 22 process;

[0084] 15) The first application 21 process sends the image acquisition request A of the first application 21 process and the image acquisition request B of the second application 22 process to the camera service 24 based on the recreated image acquisition channel;

[0085] 16) The camera service 24 prioritizes the received image acquisition requests, retrieves the target image acquisition request from the request queue through the camera driver, and sends the target image acquisition request to the camera device.

[0086] 17) The camera device fills the acquired image data into the image storage area A corresponding to the first application process and the image storage area B corresponding to the second application process based on the image storage address carried in the target image acquisition request.

[0087] Here, the camera device obtains the image storage address (Surface object) carried in the target image acquisition request, and requests the allocation of an image storage area from the image buffer compositing service layer (SurfaceFlinger) 25 through the graphics buffer producer (GraphicBufferProducer) to obtain the image storage area (GraphicBuffer) corresponding to the Surface object. Simultaneously, a mapping relationship is established between the image storage address of the second application process and this image storage area, so that the image storage area is mapped to the second application process. Then, the acquired image data is written to this image storage area. Here, this image storage area can be image storage area A corresponding to the first application process and image storage area B corresponding to the second application process.

[0088] Here, image storage region A (GraphicBuffer A) and image storage region B (GraphicBuffer B) are memory-mapped as anonymous shared memory to the first application process and the second application process, respectively.

[0089] This application collects image acquisition requests from multiple application processes in a cross-process manner by having a primary application that continuously occupies the camera. Then, it fills the image storage areas of these multiple application processes with image data through an image acquisition channel established by the primary application for all application processes. This eliminates the need to modify the Android system's camera service or architecture; camera data sharing can be achieved solely through the application layer that continuously occupies the camera. No system customization is required, facilitating the rapid deployment of camera sharing capabilities and enhancing practicality.

[0090] Figure 3 This is a schematic diagram illustrating the method for sharing a camera in this application. Figure 3 ,like Figure 3 As shown, this method is applied to a second application in an electronic device, and the method includes:

[0091] Step 301: Send the first service call request to the first application process that has been occupying the camera for a long time;

[0092] Step 302: If the first service call request is successfully responded to, a communication connection is established with the first application process;

[0093] Step 303: Send image acquisition information to the first application process based on the communication connection. The image acquisition information includes at least an image storage address and template information.

[0094] Step 304: Obtain the image data captured by the camera through the image storage area corresponding to the image storage address; wherein, the image storage area is allocated by the camera service layer from the image cache synthesis service layer; the image data is sent by the camera service layer to the image storage area based on the image acquisition request sent by the first application process, and the image acquisition request is generated by the first application process according to the image storage address and the template information.
