Description

Camera sharing methods, devices, equipment and media

[0003] With the rapid development of economy and technology, wearable devices, especially head-mounted devices (such as AR, VR, MR and XR smart glasses or helmets), are widely used in various fields.

[0004] Multiple applications running simultaneously is a typical application scenario in head-mounted displays (HMDs), where multiple applications run in the foreground on the HMD simultaneously. In this scenario, the HMD may simultaneously run at least two processes that need to access the same camera.

[0005] However, when a head-mounted device simultaneously launches at least two processes that need to access the same camera, once that same camera is accessed by one process, it cannot be accessed by other processes. This results in at least two processes that need to access the same camera being unable to simultaneously obtain camera data, or the camera function of the later-launched process becoming invalid.

[0046] Electronic device 1000 may include a processor 1100, a memory 1200, an interface device 1300, a communication device 1400, a display device 1500, an input device 1600, a speaker 1700, a microphone 1800, etc. The processor 1100 may be a central processing unit (CPU), a microprocessor (MCU), etc. The memory 1200 may include, for example, ROM (Read-Only Memory), RAM (Random Access Memory), or non-volatile memory such as a hard disk. The interface device 1300 may include, for example, a USB interface, a headphone jack, etc. The communication device 1400 may be capable of wired or wireless communication. The display device 1500 may be, for example, an LCD screen, a touch screen, etc. The input device 1600 may include, for example, a touch screen, a keyboard, etc. Users can input / output voice information through the speaker 1700 and the microphone 1800.

[0047] Although multiple devices are shown for electronic device 1000 in FIG1, the present invention may refer to only some of the devices therein. For example, electronic device 1000 may refer to only memory 1200 and processor 1100.

[0048] In an embodiment of the present invention, the memory 1200 of the electronic device 1000 is used to store instructions for controlling the processor 1100 to execute the camera sharing method provided in the embodiment of the present invention.

[0049] In the above description, those skilled in the art can design instructions based on the scheme disclosed in this invention. How the instructions control the processor to operate is well known in the art, and therefore will not be described in detail here.

[0050] This invention provides a camera sharing method, which is applied to the electronic device shown in Figure 1. As shown in Figure 2, the camera sharing method provided by this invention includes the following steps S2100 to S2500.

[0051] Step S2100: For any camera, obtain at least two target camera processes corresponding to the camera, wherein the at least two target camera processes are camera processes that have the possibility of calling the camera simultaneously.

[0052] Electronic devices typically have multiple cameras, such as wide-angle lenses, ultra-wide-angle lenses, and telephoto lenses. A single camera can be invoked by at least two camera processes. When at least two camera processes invoke a single camera, there is a possibility that at least two camera processes will invoke that camera simultaneously. In this embodiment, for any camera on the electronic device, there will be at least two camera processes that simultaneously invoke that camera, denoted as the at least two target camera processes of that camera.

[0053] In one example, the camera process can be a camera algorithm, such as 6DoF and gesture algorithms. The camera process can also be a camera application, such as a social application that enables video calls or a search application that allows scanning.

[0054] If at least two target camera processes corresponding to the camera are obtained based on the above step S2100, the following step S2200 is executed to allocate memory for each target camera process.

[0055] Step S2200: For any target camera process, allocate first memory for the target camera process according to the image configuration requirements corresponding to the target camera process.

[0056] Image configuration requirements describe the specifications of the image data needed for the corresponding target camera process. In one embodiment, image configuration requirements include at least one of image size and image format. The image format may be, for example, RGB or YUV format.

[0057] For each camera process, there are corresponding image configuration requirements. Based on this, the target camera process also has image configuration requirements.

[0058] In this embodiment, based on the above step S2200, a corresponding first memory is allocated in advance for each target camera process.

[0059] Step S2300: When any target camera process is started, control the camera to acquire image data according to the corresponding image configuration requirements, and allocate second memory for the target camera process.

[0060] When any target camera process is started, for example, when target camera process 1 is turned on, at this time, while allocating second memory for target camera process 1, the camera is controlled to acquire image data according to the corresponding image configuration requirements of target camera 1.

[0061] In one example, taking the image configuration requirement as including image size, and the image configuration requirement corresponding to the target camera process 1 as 640*480, based on the above step S2300, the image data acquired by the camera is image data of 640*480 specification.

[0062] It should be noted that step S2300 above is the step performed by the electronic device when the camera process is started in conventional technology.

[0063] Furthermore, based on the following step S2400, the image data acquired by the camera is stored in the first memory corresponding to the activated target camera process.

[0064] Step S2400: Store the image data in the first memory corresponding to the target camera process.

[0065] Step S2500: Copy the image data in the first memory corresponding to the target camera process to the second memory.

[0066] When the target camera process is target camera process 1, since the first memory stores image data acquired by the camera according to the image configuration requirements corresponding to target camera process 1, based on the above step S2500, the image data in the first memory that meets the image configuration requirements corresponding to target camera process 1 can be completely copied to the second memory. At this time, the second memory stores the image data acquired according to the image configuration requirements corresponding to target camera process 1. In this way, target camera process 1 can successfully access the image data in the second memory.

[0067] Based on the above steps S2100 to S2500, at least two target camera processes can successfully invoke a camera, that is, at least two camera processes can share the camera.

[0068] It should be emphasized that the target camera process involved in steps S2300 to S2400 above is specifically the target camera process that was started as described in step S2300 above.

[0069] This invention provides a camera sharing method, comprising: for any camera, acquiring at least two target camera processes corresponding to the camera, wherein the target camera processes are camera processes that may simultaneously call the camera; for any target camera process, allocating first memory for the target camera process according to the image configuration requirements corresponding to the target camera process; when any target camera process is started, controlling the camera to acquire image data according to the image configuration requirements corresponding to the target camera process, and allocating second memory for the target camera process; storing the image data in the first memory corresponding to the target camera process; and copying the image data in the first memory corresponding to the target camera process to the second memory. This method enables at least two target camera processes to successfully call a camera, that is, it realizes camera sharing by at least two camera processes.

[0070] In one embodiment of the present invention, the above step S2100 can be specifically implemented by the following step S2110.

[0071] Step S2110: For any camera, if at least one of the at least two target camera processes is started, obtain at least two target camera processes corresponding to the camera.

[0072] In this embodiment, for any camera, if one of the at least two target camera processes is started, it indicates that there is a possibility that other target camera processes besides the one that was started may also be started. In this case, by obtaining the at least two target camera processes corresponding to the camera and then executing steps S2200 to S2500, a successful call to a camera by at least two target camera processes can be achieved, i.e., camera sharing by at least two camera processes is realized.

[0073] By using the above step S2110, unnecessary execution of steps S2200 to S2500 can be avoided, thus preventing the waste of computing resources of electronic devices.

[0074] In one embodiment of the present invention, the camera sharing method provided by the present invention further includes the following step S2210 before the above step S2200.

[0075] Step S2310: For any target camera process, find the image configuration requirements corresponding to the target camera process from the preset mapping relationship.

[0076] Among them, the preset mapping relationship is a mapping relationship that represents the camera process and the corresponding image configuration requirements.

[0077] In this embodiment, the image configuration requirements corresponding to any target camera process are known in advance. Therefore, a preset mapping relationship can be generated in advance and stored in the electronic device. The preset mapping relationship represents the mapping relationship between the camera process and the corresponding image configuration requirements.

[0078] Furthermore, for any camera, the image configuration requirements corresponding to the target camera process that was initiated are found in the preset mapping relationship.

[0079] In one embodiment of the present invention, step S2500 is specifically implemented through the following step S2510:

[0080] Step S2510: After the data in the first memory is filled, copy the image data in the first memory corresponding to the target camera process to the second memory.

[0081] In this embodiment, after the first memory is filled with data, the image data corresponding to the target camera process in the first memory is copied to the second memory. This avoids redundant or incorrect copying of image data from the first memory to the second memory, which could lead to errors in the image data in the second memory.

[0082] The camera sharing method provided by this invention can be implemented through a camera daemon process. Based on this, and combining the above embodiments and the camera architecture shown in Figure 3, and taking APP1 and APP2 as the target camera processes respectively, and APP1's image configuration requirement being an image size of 640*480, and APP2's image configuration requirement being an image size of 720*1280 and 1280*1920 as an example, the specific implementation of the above steps S2200 to S2500 is as follows:

[0083] S1, the camera daemon sends the image configuration requirements of 640*480 for APP1 and the image configuration requirements of 720*1280 and 1280*1920 for APP2 to the camera driver through the first path. The first path refers to the path from the camera server, through the config in the camera provider to the camera driver.

[0084] S2, after receiving the image configuration requirements of 640*480 from APP1 and 720*1280 and 1280*1920 from APP2, the camera driver instructs the camera provider to request memory s_buffer1 for 640*480, memory s_buffer2 for 720*1280, and memory s_buffer3 for 1280*1920.

[0085] S3, according to the instructions in S2 above, the camera provider requests memory s_buffer1 corresponding to 640*480, memory s_buffer2 corresponding to 720*1280 and memory s_buffer3 corresponding to 1280*1920.

[0086] S4, when APP1 is started, APP1 controls the camera to acquire image data according to the image configuration requirements of 640*480, and instructs the camera provider to request the memory buffer1 corresponding to 640*480;

[0087] S5, the camera daemon stores the image data captured by the camera in s_buffer1, and copies the data in s_buffer1 to buffer1.

[0088] S6, when APP2 is started, APP1 controls the camera to collect image data according to the image configuration requirements of 720*1280 and 1280*1920, and instructs the camera provider to apply for memory buffer2 corresponding to 720*1280 and memory buffer3 corresponding to 1280*1920.

[0089] S7, the camera daemon stores the 720*1280 image data captured by the camera in s_buffer2 and copies the data in s_buffer2 to buffer2. It also stores the 1280*1920 image data captured by the camera in s_buffer3 and copies the data in s_buffer3 to buffer3.

[0090] As can be understood, as shown in Figure 3, after S7 above, the image data in buffer1, buffer2 and buffer3 are fed back to APP1 and APP2 through the camera server.

[0091] It should be noted that s_buffer1, s_buffer2, and s_buffer3 in S1-S5 above correspond to the first memory in steps S2100 to S2500 above. buffer1 in S1-S5 above is the second memory corresponding to APP1. buffer2 and buffer3 are the second memory corresponding to APP2.

[0092] The present invention also provides a camera sharing device 400, as shown in FIG4, comprising:

[0093] The acquisition module 410 is used to acquire, for any camera, at least two target camera processes corresponding to the camera, wherein the at least two target camera processes are camera processes that have the possibility of calling the camera simultaneously;

[0094] The application module 420 is used to apply for first memory for any target camera process according to the image configuration requirements corresponding to the target camera process.

[0095] The control module 430 is used to control the camera to acquire image data according to the corresponding image configuration requirements when any of the target camera processes are started, and to allocate second memory for the target camera process.

[0096] Storage module 440 is used to store the image data in the first memory corresponding to the target camera process;

[0097] The copy module 450 is used to copy the image data in the first memory corresponding to the target camera process to the second memory.

[0098] In one embodiment of the present invention, the acquisition module 410 is specifically used to: for any camera, if one of the at least two target camera processes is started, acquire at least two target camera processes corresponding to the camera.

[0099] In one embodiment of the present invention, the copying module 450 is specifically used to: copy the image data in the first memory corresponding to the target camera process to the second memory after the first memory has been filled with data.
