Description

Technical Field

[0001] This application relates to the field of terminal technology, and in particular to temperature control methods and related devices. Background Technology

[0002] In scenarios such as video conferencing or video teaching, users can use the camera of electronic device B on electronic device A. This scenario can be called a shared camera scenario.

[0003] However, when electronic device A uses the camera of electronic device B, it increases the system load of electronic device B, which may cause the temperature of electronic device B to rise and reduce the user experience. Summary of the Invention

[0004] The temperature control method and related apparatus provided in this application can reduce the frame rate of the camera capturing images and the bit rate of the electronic device transmitting images when the temperature of the electronic device using the camera rises, so that the temperature of the electronic device will not be too high.

[0005] In a first aspect, the temperature control method provided in this application includes: a first electronic device calling a camera device of a second electronic device; the second electronic device using the camera device to acquire images and transmitting the images to the first electronic device; wherein, during the process of the second electronic device acquiring images using the camera device, when the temperature of the second electronic device rises to a first preset value, if the first frame rate of the image acquired by the camera device is greater than a target frame rate, the second electronic device reduces the frame rate of the image acquired by the camera device; otherwise, if the first frame rate is less than or equal to the target frame rate, the second electronic device reduces the bit rate of the transmitted image. In this way, the frame rate of the image acquired by the camera and the bit rate of the image transmitted by the electronic device can be adaptively adjusted based on a baseline frame rate, a baseline bit rate, and temperature levels without significantly affecting the user experience, thereby regulating the temperature of the electronic device and reducing the probability of the electronic device overheating.

[0006] In one possible implementation, during the process of the second electronic device acquiring images using a camera: at a first moment, the temperature of the second electronic device is a first temperature, and the frame rate of the image acquired by the camera is a first frame rate, which is greater than the target frame rate; at a second moment, the temperature of the second electronic device is a second temperature, and the frame rate of the image acquired by the camera is a second frame rate, wherein the second moment is later than the first moment, the second temperature is greater than the first temperature, the second frame rate is less than the first frame rate, and the second frame rate is greater than the target frame rate; at a third moment, the temperature of the second electronic device is a third temperature, and the frame rate of the image acquired by the camera is a third frame rate, wherein the third moment is later than the second moment, the third temperature is greater than the second temperature, the third frame rate is less than the second frame rate, and the third frame rate is greater than or equal to the target frame rate. This achieves a gradual reduction in the frame rate, ensuring that the decrease in frame rate is not significant, the interface display is not overly choppy, and the user experience is minimized.

[0007] In one possible implementation, between the second and third time points, the temperature of the second electronic device is a fourth temperature, and the frame rate at which the camera captures images is a second frame rate. The fourth temperature is greater than the second temperature and less than the third temperature, and both the fourth and second temperatures fall within a first preset temperature range. This eliminates the need for frequent frame rate adjustments based on temperature changes, allowing the second electronic device to transmit images to the first electronic device at a relatively stable frame rate.

[0008] In one possible implementation, the temperature level corresponding to the first temperature is designated as Level 1, the temperature level corresponding to the second temperature is designated as Level 2, the temperature level corresponding to the third temperature is designated as Level 3, and the temperature level corresponding to the fourth temperature is designated as Level 2. This reduces the number of steps involved in adjusting the frame rate, thereby reducing memory resource usage.

[0009] In one possible implementation, during the process of the second electronic device acquiring images using a camera: at the fourth moment, the temperature of the second electronic device is the fifth temperature, the frame rate of the image acquired by the camera is the first frame rate, and the bit rate of the image transmitted by the second electronic device is the first bit rate, which is greater than the target frame rate; at the fifth moment, the temperature of the second electronic device is the sixth temperature, the frame rate of the image acquired by the camera is the target frame rate, and the bit rate of the image transmitted by the second electronic device is the second bit rate, wherein the fifth moment is later than the fourth moment, the sixth temperature is greater than the fifth temperature, and the second bit rate is less than the first bit rate; at the sixth moment, the temperature of the second electronic device is the seventh temperature, the frame rate of the image acquired by the camera is the target frame rate, and the bit rate of the image transmitted by the second electronic device is the third bit rate, wherein the sixth moment is later than the fifth moment, the seventh temperature is greater than the sixth temperature, and the third bit rate is less than the second bit rate. In this way, the second electronic device first reduces the frame rate and then reduces the bit rate. Since the bit rate also decreases when the frame rate decreases, the probability of interface stuttering and / or blurring can be reduced.

[0010] In one possible implementation, between the fifth and sixth moments, the temperature of the second electronic device is an eighth temperature, the frame rate of the image captured by the camera device is the target frame rate, and the bit rate of the image transmitted by the second electronic device is a second bit rate. The eighth temperature is greater than the sixth temperature and less than the seventh temperature, and both the eighth and sixth temperatures fall within a second preset temperature range. This eliminates the need for frequent bit rate adjustments based on temperature changes, allowing the second electronic device to transmit images to the first electronic device at a relatively stable bit rate.

[0011] In one possible implementation, during the process of the second electronic device acquiring images using a camera: at the seventh moment, the temperature of the second electronic device is the ninth temperature, the frame rate of the image acquired by the camera is the first frame rate, and the bit rate of the image transmitted by the second electronic device is the first bit rate, where the first frame rate is less than or equal to the target frame rate; at the eighth moment, the temperature of the second electronic device is the tenth temperature, the frame rate of the image acquired by the camera is the target frame rate, and the bit rate of the image transmitted by the second electronic device is the fourth bit rate, wherein the eighth moment is later than the seventh moment, the tenth temperature is greater than the ninth temperature, and the fourth bit rate is less than the first bit rate; at the ninth moment, the temperature of the second electronic device is the eleventh temperature, the frame rate of the image acquired by the camera is the target frame rate, and the bit rate of the image transmitted by the second electronic device is the fifth bit rate, wherein the ninth moment is later than the eighth moment, the eleventh temperature is greater than the tenth temperature, and the fifth bit rate is less than the fourth bit rate. In this way, the decrease in bit rate value will not be significant, the display effect of the interface will not be too blurry, and the user experience can be minimized.

[0012] In one possible implementation, during the process of the second electronic device acquiring images using the camera device, when the temperature of the second electronic device drops to a second preset value, if the frame rate of the image acquired by the camera device is less than a first frame rate, the second electronic device increases the frame rate. This increases the frame rate of the image acquired by the camera, thereby improving the image quality.

[0013] In one possible implementation, the second electronic device increases the frame rate by: increasing the frame rate to a first frame rate; or, increasing the frame rate to a fourth frame rate, where the fourth frame rate is lower than the first frame rate, and when the temperature of the second electronic device drops to a third preset value, increasing the fourth frame rate back to the first frame rate, where the third preset value and the second preset value belong to different temperature ranges; or, increasing the frame rate to a fourth frame rate; and when the temperature of the second electronic device is less than or equal to the second preset value within a first preset time period, increasing the fourth frame rate back to the first frame rate. In this way, after the second electronic device increases its frame rate, the frame rate of the image data received by the first electronic device also increases, thereby improving the user experience.

[0014] In one possible implementation, during the process of the second electronic device acquiring images using the camera, if the temperature of the second electronic device drops to a fourth preset value and the bit rate of the transmitted image is lower than the first bit rate, the second electronic device increases the bit rate. This increases the bit rate of the image acquired by the camera, thereby improving the image quality.

[0015] In one possible implementation, the second electronic device increases the bitrate, including: the second electronic device increasing the bitrate to a first bitrate; or, the second electronic device increasing the bitrate to a sixth bitrate, where the sixth bitrate is lower than the first bitrate, and when the temperature of the second electronic device drops to a fifth preset value, the second electronic device increases the sixth bitrate back to the first bitrate, where the fifth preset value and the fourth preset value belong to different temperature ranges; or, the second electronic device increasing the bitrate to a sixth bitrate, and when the temperature of the second electronic device is less than or equal to the fourth preset value within a second preset time period, the second electronic device increases the sixth bitrate back to the first bitrate. In this way, after the second electronic device increases its bitrate, the bitrate of the image data received by the first electronic device also increases, thereby improving the user experience.

[0016] In one possible implementation, before the first electronic device invokes the camera device of the second electronic device, the method further includes: the first electronic device displaying an interface of a target application, the interface including identifiers of one or more cameras; the identifiers of the one or more cameras including an identifier of the camera device of the second electronic device; the first electronic device invoking the camera device of the second electronic device includes: the first electronic device invoking the camera device of the second electronic device in response to a selection operation on the identifier of the camera device of the second electronic device. In this way, users can use the camera device of the second electronic device on the first electronic device for video conferencing or video teaching, thus improving the user experience.

The first electronic device is used to execute the method performed by the first electronic device in the first aspect or any possible implementation thereof.

[0018] For example, the first electronic device is used to invoke the camera device of the second electronic device and to display the interface of the target application, specifically in response to a selection operation of the identifier of the camera device of the second electronic device.

[0019] The second electronic device is used to capture images using a camera device, and also to transmit images to the first electronic device, and to reduce the frame rate of the images captured by the camera device, and specifically to reduce the bit rate of the transmitted images.

[0020] The second electronic device is also used to increase the frame rate and the bit rate.

[0021] Thirdly, embodiments of this application provide an electronic device, including a processor and a memory, wherein the memory is used to store code instructions, and the processor is used to run the code instructions to execute the method executed by the first electronic device in the first aspect or any possible implementation of the first aspect, or to execute the method executed by the second electronic device in the first aspect or any possible implementation of the first aspect.

[0036] To facilitate a clear description of the technical solutions in the embodiments of this application, some terms and technologies involved in the embodiments of this application will be briefly introduced below:

[0037] 1. Terminology

[0038] In the embodiments of this application, terms such as "first" and "second" are used to distinguish identical or similar items with substantially the same function and purpose. For example, "first chip" and "second chip" are used only to distinguish different chips and do not limit their order of execution. Those skilled in the art will understand that terms such as "first" and "second" do not limit the quantity or execution order, and that "first" and "second" do not necessarily imply that they are different.

[0039] It should be noted that, in the embodiments of this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design scheme described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0040] In this application embodiment, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, a--c, bc, or abc, where a, b, and c can be single or multiple.

[0041] In scenarios such as video conferencing or video lectures, users can use the camera of electronic device B on electronic device A. This scenario can be called a shared camera scenario. The following example uses a computer as electronic device A and a mobile phone as electronic device B to illustrate a video conferencing scenario where a user uses a mobile phone camera on a computer.

[0042] like Figure 1 As shown, computer 100 can establish a connection with mobile phone 101. Computer 100 can display the interface 1001 of a certain application, which can conduct video conferencing. The interface 1001 of this application can include video conferencing-related functions, such as mute function, camera function 1002, interactive function, more functions, sharing function, etc. The interface 1001 may also include an end-sharing button and an end-live button. It is understood that the application can provide functions such as camera on / off, but the content displayed on the interface 1001 of different applications may vary, and this embodiment does not limit the scope of the application.

[0043] The camera function 1002 may include enabling and disabling the camera, and may also have a corresponding camera selection menu 1003. For example, the camera function may be as follows: Figure 2 As shown, the application interface can display an icon and text indicating that the camera 200 is turned on. In response to the user's operation of turning on the camera, the application interface can display an icon and text indicating that the camera 201 is turned off.

[0044] Furthermore, in response to the user clicking the drop-down arrow 202, the application interface can also display a camera selection menu 203. The camera selection menu 203 can include different types of cameras such as the device's own camera, the front-facing camera 204, and the rear-facing camera 205. The camera selection menu 203 can also provide functions such as beautification, virtual backgrounds, and video settings. It is understood that the content and functions displayed in the camera selection menu 203 may differ between different applications, and this embodiment does not limit the scope of the application.

[0045] In response to the user's selection of the front-facing camera 204, the selected front-facing camera 206 can be displayed in the application interface. The display method of the selected front-facing camera 206 can be customized by the application, and this embodiment does not impose any limitations on it.

[0046] As mentioned above Figure 1 As shown, when the computer 100 responds to the user's selection of the front-facing camera on the mobile phone, the mobile phone 101 can turn on the front-facing camera and use it to conduct a video conference with the computer 100.

[0047] However, using a mobile phone camera on a computer increases the system load on the phone, which may cause the phone to overheat and reduce the user experience.

[0048] In view of this, the temperature control method provided in this application embodiment can reduce the frame rate of the camera capturing images and the bit rate of the electronic device transmitting images when the temperature of the electronic device using the camera rises, so that the temperature of the electronic device will not be too high.

[0049] The temperature control method provided in this application embodiment can be applied to a communication system, which may include a first electronic device and a second electronic device.

[0050] The first electronic device and the second electronic device can be of the same type or different types.

[0051] By way of example and not limitation, in this embodiment, the electronic device can also be a wearable device. Wearable devices, also known as wearable smart devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are feature-rich, large in size, and can achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those that focus on a specific type of application function and require the use of other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0052] Furthermore, in this application embodiment, the electronic device can also be an electronic device in the Internet of Things (IoT) system. IoT is an important part of the future development of information technology. Its main technical feature is to connect objects to the network through communication technology, thereby realizing an intelligent network of human-machine interconnection and object-to-object interconnection.

[0053] The electronic equipment in the embodiments of this application may also be referred to as: user equipment (UE), mobile station (MS), mobile terminal (MT), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent, or user device, etc.

The hardware layer includes hardware such as a central processing unit (CPU), a memory management unit (MMU), and memory (also called main memory). The operating system can be any one or more computer operating systems that implement business processing through processes, such as Linux, Unix, Android, iOS, or Windows. The application layer includes applications such as browsers, address books, word processing software, and instant messaging software.

[0055] For example, the first electronic device may include the above-described Figure 1 The computer 100 in the middle, the second electronic device may include the above-mentioned Figure 1 The mobile phone 101 in the example can also be a tablet or other electronic device, and this application embodiment does not limit the scope of the device.

[0079] In the embodiments of this application, the first electronic device and the second electronic device may use the same operating system or different operating systems. The operating system may include, for example, any of the following operating systems: Linux operating system, Unix operating system, Android operating system, iOS operating system, or Windows operating system, etc.

[0080] For example, Figure 5 Taking the Android system as an example, a partial software architecture of the electronic device is illustrated. This software system can employ a layered architecture, event-driven architecture, microkernel architecture, microservices architecture, or cloud architecture.

[0081] A layered architecture divides software into several layers, each with a clear role and function. Layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into five layers, from top to bottom: the application layer, the application framework layer, the Android runtime and system libraries, the hardware abstraction layer, and the kernel layer.

[0082] The application layer can include a series of application packages. Application packages can include applications such as phone, music, calendar, camera, games, notes, and video. Applications can include system applications and third-party applications.

[0083] The application framework layer provides application programming interfaces (APIs) and a programming framework for applications in the application layer. The application framework layer includes some predefined functions.

[0084] The application framework layer may include a window manager, resource manager, notification manager, content provider, and view system, etc. In this embodiment, the application framework layer may also include a shared camera service, a temperature control service, a virtualization service, a communication service, etc.

[0085] The window manager is used to manage windowed applications. It can obtain the screen size, determine if a status bar is present, lock the screen, allow screen touch, drag the screen, and capture the screen, among other things.

[0086] The file explorer provides applications with various resources, such as localized strings, icons, images, layout files, video files, and more.

[0087] Content providers enable data sharing between different applications, allowing one application to access data in another while ensuring the security of the accessed data.

[0088] The view system can be responsible for drawing the application's interface and handling events.

[0089] The shared camera service can be used to perform camera-related business processes. For example, the shared camera service can interact with communication services through signaling, such as issuing signaling to start or stop the camera. The shared camera service can also enable the camera through virtualization services and synchronize the camera status.

[0090] Temperature control services provide an interface for temperature changes, allowing electronic devices to revert to their original temperature and / or temperature level when the temperature rating changes. Temperature control services can also be called temperature management services.

[0091] Virtualization services can be used to enable the sharing of cameras between devices. They can also be used to adjust the frame rate of images captured by cameras and the bit rate of images transmitted by electronic devices based on temperature adjustment information issued by the shared camera service. Furthermore, virtualization services can interact with communication services to transmit camera data and exchange signaling.

[0092] The communication service can transmit camera data between two devices. For example, camera data may include the frame rate of the image captured by the camera, the bit rate of the image transmitted by the electronic device, and the content captured by the camera. The communication service can also interact with the shared camera service and / or virtualization service through signaling. For example, the signaling interaction between the communication service and the shared camera service may include turning the camera on or off, and the signaling interaction between the communication service and the virtualization service may include parameter negotiation.

[0093] The Android runtime consists of core libraries and a virtual machine. The Android runtime is responsible for scheduling and managing the Android system.

[0094] The core library consists of two parts: one part is the functionalities that need to be called by the Java language, and the other part is the Android core library.

[0095] The application layer and application framework layer run in a virtual machine. The virtual machine executes the Java files of the application layer and application framework layer as binary files. The virtual machine is used to perform functions such as object lifecycle management, stack management, thread management, security and exception management, and garbage collection. For example, in the embodiments of this application, the virtual machine can be used to perform functions such as turning the camera on or off, detecting the temperature of the electronic device, and adjusting the frame rate and / or bit rate of the image captured by the camera.

[0096] System libraries, also known as the native layer, can include multiple functional modules. Examples include media libraries, function libraries, and graphics processing libraries (such as OpenGL ES).

[0097] The media library supports playback and recording of various common audio and video formats, as well as still image files. It supports multiple audio and video encoding formats, such as MPEG4, H.264, MP3, AAC, AMR, JPG, and PNG.

[0098] The function library provides developers with API interfaces for various services, making it easy for them to quickly integrate and implement various functions.

[0099] The graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing.

[0100] The Hardware Abstraction Layer (HAL) is a layer of abstraction located between the kernel layer and the Android runtime. The HAL can be a wrapper around hardware drivers, providing a unified interface for calls from upper-layer applications.

[0101] The kernel layer is the layer between hardware and software. The kernel layer can include Bluetooth drivers, Wi-Fi drivers, display drivers, camera drivers, audio drivers, battery drivers, CPU drivers, USB drivers, and more.

[0102] It should be noted that the embodiments of this application are only illustrated using the Android system. In other operating systems (such as Windows system, iOS system, etc.), as long as the functions implemented by each functional module are similar to those in the embodiments of this application, the solution of this application can also be implemented.

[0103] For ease of description, this application uses a shared camera scenario where a user uses a mobile phone camera on a computer as an example to illustrate the temperature control method.

[0104] In this context, the computer side can be referred to as the user, and the mobile phone side can be referred to as the user. Both the user and the user can include various functional modules that enable camera sharing, such as camera sharing services, virtualization services, communication services, and temperature control services.

[0105] For ease of description, the user's shared camera service will be referred to as the first shared camera service, the user's virtualization service as the first virtualization service, and the user's communication service as the first communication service. The user's shared camera service will be referred to as the second shared camera service, the user's virtualization service as the second virtualization service, and the user's communication service as the second communication service.

[0106] Figure 6 The diagram illustrates the interaction between software modules on a computer and a mobile phone.

[0107] The user's application layer can include several third-party applications capable of video conferencing, where users can select the camera of the party being used. For example, if a user selects the front-facing camera of the party being used, when the user responds to the user's action of turning on the front-facing camera, the user can pass the information about turning on the front-facing camera to the first shared camera service in the application framework layer.

[0108] After receiving information that the front-facing camera of the user is turned on, the first shared camera service can enable and synchronize the status of the user's camera through the first virtualization service.

[0109] Camera enabling can include enabling the user's camera and enabling the user's camera. Camera enabling can be understood as the first virtualization service's identification and mounting of the camera. When the first virtualization service identifies the user's or user's camera and mounts the camera to the user, it means that the camera has the ability to be used.

[0110] The first virtualization service can transmit camera enabling data to the second virtualization service through the data channel established between the first and second communication services. Once the second virtualization service successfully enables the camera, it can transmit this success information back to the first virtualization service through the same data channel. The first virtualization service can then return a callback message indicating successful camera enabling to the first shared camera service. This callback message can be returned to the third-party application, allowing the application's interface to display the camera of the user. For example, the camera displayed on the third-party application's interface could include the aforementioned... Figure 2 The phone's front-facing camera 204 and rear-facing camera 205.

[0111] The synchronization of camera status can include the synchronization of camera enable status, as well as the synchronization of camera status during use, such as camera on, camera in the process of opening, camera successfully opening, camera successfully closing, etc.

[0112] On the other hand, the first shared camera service can transmit control signaling to the first communication service. This control signaling may include selecting a front or rear camera, turning the camera on or off, etc. For example, the first shared camera service can transmit information about turning on the user's front camera to the first communication service.

[0113] The first communication service can transmit camera data between the user and the user. The first communication service can transmit the information of the user's front-facing camera to the user's second communication service through the Bluetooth or Wi-Fi module of the hardware abstraction layer and the Bluetooth or Wi-Fi driver of the kernel layer.

[0114] Within the application framework layer of the user, the second communication service can report information about the user's front-facing camera being turned on to the second shared camera service. The second shared camera service can then pass this information to the second virtualization service, which in turn starts the camera driver by calling the camera enable interface of the hardware abstraction layer. Once the user's camera is turned on, the second virtualization service can transmit the result of the camera being turned on to the second communication service through the second shared camera service.

[0115] The second communication service can transmit camera data between the user and the user, and return the camera activation result to the user's first communication service. The first communication service can report this result to the first shared camera service, which can then return the result to the third-party application. The third-party application can then display the camera activation icon and text information on its interface.

[0116] Understandably, the second virtualization service can also pass the camera activation result to the second communication service, which then returns the camera activation result to the first communication service. The first communication service can then report the camera activation result to the first virtualization service. In other words, the first virtualization service and the first communication service can transmit camera data and exchange signaling without going through the first shared camera service. The transmitted camera data may include the frame rate of the images captured by the camera, the bit rate of the images transmitted by the user, and the content captured by the camera. The exchanged signaling may include parameter negotiation, camera selection, and camera capability activation.

[0117] Understandably, when the third-party application starts, the first shared camera service, the first virtualization service, the first communication service, the second virtualization service, and the second communication service can all start and run, enabling the camera of the user or the device being used. When the third-party application's interface displays a camera icon and / or camera text, it indicates that the camera has been successfully enabled and is capable of being used. When the device being used receives the message to open the camera, the second shared camera service and the temperature control service can start and run. In this way, the second shared camera service and the temperature control service only start and run when the camera is being used, saving power consumption for the device being used.

[0118] When the user receives a message to turn off the camera, the second shared camera service and the temperature control service can stop running. This way, the second shared camera service and the temperature control service operate while the camera is in use, saving power for the user. When the third-party application is closed, the first shared camera service, the first virtualization service, the first communication service, the second virtualization service, and the second communication service can all stop running.

[0119] The following is combined Figure 7 This paper describes the implementation flow of the temperature control method according to embodiments of this application. It should be noted that the computer and mobile phone interact with each other via a communication channel between a first communication service and a second communication service. Figure 7 The implementation process does not currently reflect the interaction between the first and second communication services.

[0120] 1. Enable camera sharing service.

[0121] When a user uses a mobile phone's camera in a third-party application on their computer, the application can send camera usage information to the phone through the computer's primary camera sharing service and primary communication service. Upon receiving this message, the phone can activate a secondary camera sharing service. The specific process of the computer sending camera usage information to the phone can be found above. Figure 6 The descriptions in the corresponding embodiments will not be repeated here.

[0122] 2. Report the camera's initial frame rate and initial resolution.

[0123] After the second camera sharing service is started, third-party applications can report the camera initial frame rate and camera initial resolution to the first virtualization service through the first camera sharing service. It is understandable that different applications may have different camera initial frame rates and camera initial resolutions.

[0124] The first virtualization service, based on the communication channel between the first and second communication services, transmits the camera's initial frame rate and initial resolution to the second virtualization service. The second virtualization service can then report the camera's initial frame rate and initial resolution to the second camera sharing service. It is understood that the second camera sharing service can convert the camera's initial resolution into an initial bitrate, and subsequently, it can save the initial frame rate and initial bitrate for later use. The initial frame rate can also be referred to as the baseline frame rate or base frame rate, and the initial bitrate can also be referred to as the baseline bitrate or base bitrate.

[0125] For example, the camera initialization frame rate can be 30 frames per second (fps), and the camera initialization resolution can be 1080P. The second camera sharing service can convert the camera initialization resolution into the camera initialization bitrate, for example, the camera initialization bitrate can be 5 megabits per second (Mbps).

[0126] 3. Register temperature monitoring callback.

[0127] To adjust the frame rate of the camera or the bit rate of the image transmitted by the phone in a timely manner when the phone's temperature rises or falls, the second camera sharing service can register a temperature monitoring callback interface with the temperature control service. When the temperature of the phone's casing changes, the second camera sharing service can obtain the temperature and / or temperature level of the phone's casing through this callback interface. In this embodiment, the phone casing temperature can be understood as the phone's surface temperature, also referred to as the shell temperature or front shell temperature; the frame rate of the camera's image acquisition can be simply referred to as the frame rate; and the bit rate of the image transmitted by the phone can be simply referred to as the bit rate.

[0128] In possible implementations of the temperature control service to obtain the shell temperature, the phone's temperature sensor can report the shell temperature to the temperature control service, or the temperature control service can periodically call relevant interfaces to detect the shell temperature. This application embodiment does not limit this.

[0129] It is understandable that the temperature control service can adjust the corresponding temperature level according to different temperature changes. For example, Table 1 below can show the correspondence between shell temperature and temperature level.

[0130] Table 1

[0131] Entering temperature retreat temperature Temperature rating Shell temperature 37℃ Front shell temperature 35℃ 1 Shell temperature 40℃ Front shell temperature 38℃ 2 Shell temperature 43℃ Front shell temperature 41℃ 3 Shell temperature 48℃ Front shell temperature 46℃ 4

[0132] The "entry temperature" can be understood as the temperature level increasing as the casing temperature rises to a certain level. For example, when the casing temperature rises to 37℃, the corresponding temperature level is 1; when the casing temperature rises to 40℃, the corresponding temperature level increases to 2. When the casing temperature is below 37℃, the corresponding temperature level is 0, which can be understood as the default temperature level for the phone.

[0133] The temperature drop-off can be understood as the temperature level decreasing when the shell temperature drops to a certain level. For example, when the shell temperature drops to 41℃, the corresponding temperature level is 2, meaning the shell temperature has dropped to a lower temperature level; similarly, when the shell temperature drops to 38℃, the corresponding temperature level drops to 1.

[0134] It is understood that the entry temperature, exit temperature, and temperature level can all be customized by the temperature control service, and the specific values ​​of the entry temperature, exit temperature, and temperature level are not limited in this embodiment. Furthermore, the change in shell temperature and the change in temperature level may not be positively correlated; for example, as the shell temperature increases, the temperature level may decrease accordingly, and as the shell temperature decreases, the temperature level may increase accordingly. The specific relationship between shell temperature and temperature level is not limited in this embodiment.

[0135] 4. Adjust the temperature level to 3.

[0136] When the second camera sharing service receives a temperature level 3 callback, the corresponding casing temperature rises to 43℃, indicating that the current phone temperature is relatively high and may affect the user experience. Therefore, the second camera sharing service can activate a temperature level 3 cooling strategy.

[0137] 5. Activate the temperature level 3 cooling strategy.

[0138] In possible implementations, cooling strategies may include (1) reducing the frame rate and / or (2) reducing the bit rate.

[0139] (1) Reduce the frame rate.

[0140] The second camera sharing service can reduce the frame rate. Specifically, when the base frame rate is greater than a preset minimum frame rate, the second camera sharing service can reduce the frame rate to 2 / 3 of the base frame rate. If the temperature level continues to rise, the second camera sharing service can reduce the frame rate to 1 / 2 of the base frame rate. Different electronic devices can have different preset minimum frame rate values; for example, the preset minimum frame rate can be 15 fps. This application embodiment does not limit the value of the preset minimum frame rate.

[0141] It should be noted that the reduced frame rate value must not be lower than the preset minimum frame rate. In other words, if the reduced frame rate is lower than the preset minimum frame rate, the second camera sharing service can set the frame rate to the preset minimum frame rate. This can basically maintain the smoothness of the image, thus ensuring that the user experience is not too bad.

[0142] For example, with a base frame rate of 30fps and a preset minimum frame rate of 15fps, when the second camera sharing service detects that the temperature level has risen from temperature level 2 to temperature level 3, a cooling strategy can be implemented. Since the base frame rate is greater than the preset minimum frame rate, the second camera sharing service can reduce the frame rate to around 20fps. If the temperature level continues to rise, from temperature level 3 to temperature level 4, the second camera sharing service can reduce the frame rate to around 15fps.

[0143] (2) Reduce bit rate.

[0144] When the frame rate is less than or equal to a preset minimum frame rate, the second camera sharing service can reduce the bitrate. Situations where the frame rate is less than or equal to the preset minimum frame rate may include (a) the base frame rate is less than or equal to the preset minimum frame rate; and (b) the second camera sharing service reduces the frame rate to the preset minimum frame rate.

[0145] (a) The baseline frame rate is less than or equal to the preset minimum frame rate.

[0146] When the baseline frame rate is less than or equal to the preset minimum frame rate, the second camera sharing service can maintain the frame rate and reduce the bitrate to 2 / 3 of the baseline bitrate. If the temperature level continues to rise, the second camera sharing service can reduce the bitrate to 1 / 2 of the baseline bitrate.

[0147] For example, with a base frame rate of 15fps, a preset minimum frame rate of 15fps, and a base bitrate of 2.5Mbps, when the second camera sharing service detects that the temperature level has risen from temperature level 2 to temperature level 3, a cooling strategy can be implemented. Since the base frame rate equals the preset minimum frame rate, the second camera sharing service can maintain the frame rate while reducing the bitrate to approximately 1.7Mbps. If the temperature level continues to rise, from temperature level 3 to temperature level 4, the second camera sharing service can reduce the bitrate to approximately 1.2Mbps.

[0148] (b) The second camera sharing service will reduce the frame rate to the preset minimum frame rate.

[0149] When the second camera sharing service reduces the frame rate to a preset minimum frame rate, but the temperature level continues to rise or the shell temperature continues to rise within a first preset time period, the second camera sharing service can maintain the frame rate unchanged and reduce the bitrate to 2 / 3 of the base bitrate. If the shell temperature continues to rise within the first preset time period, the second camera sharing service can reduce the bitrate to 1 / 2 of the base bitrate. The first preset time period can be customized by the second camera sharing service; for example, it can be 5 minutes. This application embodiment does not limit the value of the first preset time period.

[0150] For example, with a base frame rate of 30fps, a preset minimum frame rate of 15fps, a base bitrate of 5Mbps, and a first preset time period of 5 minutes, when the temperature level rises from temperature level 3 to temperature level 4, the second camera sharing service will reduce the frame rate to 15fps. Since a lower frame rate leads to a corresponding decrease in bitrate, the bitrate can be reduced to approximately 2.5Mbps. If the housing temperature continues to rise within 5 minutes, the second camera sharing service can reduce the bitrate to approximately 1.7Mbps. If the housing temperature continues to rise within 5 minutes, the second camera sharing service can reduce the bitrate to approximately 1.2Mbps.

[0151] It is understood that the aforementioned second camera sharing service reducing the frame rate to 2 / 3 or 1 / 2 of the base frame rate and reducing the bit rate to 2 / 3 or 1 / 2 of the base bit rate can be set by experience. The second camera sharing service can also reduce the frame rate or bit rate to other values ​​respectively. This application embodiment does not limit this.

[0152] The second camera sharing service first reduces the frame rate to 2 / 3 of the base frame rate, then to 1 / 2 of the base frame rate, and / or the second camera sharing service first reduces the bit rate to 2 / 3 of the base bit rate, then to 1 / 2 of the base bit rate. This can achieve the effect of gradually reducing the frame rate or bit rate. In this way, the decrease in frame rate or bit rate will not be too large, and the display effect of the interface will not be too laggy and / or too blurry, so as to minimize the impact on the user experience.

[0153] Of course, the temperature control method in this application embodiment can also reduce the frame rate to a minimum value all at once, for example, reduce the frame rate to half of the base frame rate, and / or reduce the bit rate to a minimum value all at once, for example, reduce the bit rate to half of the base bit rate. The temperature control method in this application embodiment can also reduce the frame rate and bit rate more times, without limitation.

[0154] In the above implementation, when the frame rate cannot be reduced further, the bitrate can be reduced. This is because the bitrate also decreases when the frame rate decreases, so it is not necessary to reduce the bitrate at the same time. If both the frame rate and bitrate are reduced simultaneously, the interface is likely to experience stuttering and / or blurry display effects, resulting in a poor user experience.

[0155] Of course, the temperature control method in this application embodiment can also simultaneously reduce the frame rate and bit rate, or reduce the bit rate first and then the frame rate, without limitation. After the second camera sharing service executes the cooling strategy, the second virtualization service can reduce the encoder load and the amount of data transmitted. In this way, the frame rate and bit rate of the image data received by the computer side also decrease, thereby reducing the temperature of the mobile phone.

[0156] When the temperature of the mobile phone decreases, the temperature control method of this application embodiment can also increase the frame rate of the image captured by the camera and the bit rate of the image transmitted by the mobile phone, thereby improving the image quality.

[0157] 6. Adjust back to temperature level 2.

[0158] When the second camera sharing service receives the callback information that the temperature level has fallen back to 2, the corresponding shell temperature drops to 41°C, indicating that the phone temperature is not too high. Therefore, the second camera sharing service can (1) increase the frame rate and / or (2) increase the bit rate.

[0159] 7. Lower temperature increases frame rate and bit rate.

[0160] (1) Increase frame rate.

[0161] If the second camera sharing service used a method to reduce the frame rate before increasing the frame rate, then the second camera sharing service can increase the frame rate.

[0162] In one possible implementation to improve the frame rate, the second camera sharing service can first increase the frame rate to 2 / 3 of the base frame rate, and if the temperature level continues to drop, the second camera sharing service can increase the frame rate back to the base frame rate.

[0163] For example, with a base frame rate of 30fps and a current frame rate of 15fps, if the temperature level decreases, for instance, from temperature level 3 to temperature level 2, the second camera sharing service can increase the frame rate from 15fps to approximately 20fps. If the temperature level continues to decrease, from temperature level 2 to temperature level 1, the second camera sharing service can increase the frame rate from 20fps to 30fps.

[0164] Another possible implementation to improve the frame rate is the second camera sharing service, which can boost the frame rate to the baseline frame rate in one go.

[0165] For example, with a base frame rate of 30fps and a current frame rate of 15fps, if the temperature level drops, for example from temperature level 3 to temperature level 2, the second camera sharing service can increase the frame rate from 15fps to 30fps.

[0166] In another possible implementation of frame rate enhancement, after the second camera sharing service increases the frame rate to 2 / 3 of the base frame rate, if the shell temperature does not rise within a second preset time period, the second camera sharing service can then increase the frame rate back to the base frame rate. The second preset time period can be customized by the second camera sharing service; for example, it can be 3 minutes. The first and second preset time periods can be the same or different. In this embodiment, the value of the second preset time period is not limited.

[0167] For example, with a base frame rate of 30fps, a current frame rate of 15fps, and a second preset time period of 3 minutes, if the temperature level decreases, for example from temperature level 3 to temperature level 2, the second camera sharing service can increase the frame rate from 15fps to approximately 20fps. If the casing temperature does not rise within 3 minutes, then after 3 minutes, the second camera sharing service can increase the frame rate from 20fps to 30fps.

[0168] (2) Increase the bit rate.

[0169] If the second camera sharing service used a method to reduce the bitrate before increasing the bitrate, then the second camera sharing service can increase the bitrate.

[0170] In one possible implementation to increase the bitrate, the second camera sharing service can first increase the bitrate to 2 / 3 of the base bitrate, and if the temperature level continues to rise, the second camera sharing service can increase the bitrate to the base bitrate.

[0171] For example, with a base bitrate of 5 Mbps and a current bitrate of 2.5 Mbps, if the temperature level decreases, for instance, from temperature level 3 to temperature level 2, the second camera sharing service can increase the bitrate from 2.5 Mbps to approximately 3.3 Mbps. If the temperature level continues to decrease, from temperature level 2 to temperature level 1, the second camera sharing service can increase the bitrate from 3.3 Mbps to 5 Mbps.

[0172] Another possible way to increase the bitrate is through a second camera sharing service, which can boost the bitrate to the baseline bitrate in one go.

[0173] For example, with a base bitrate of 5Mbps and a current bitrate of 2.5Mbps, if the temperature level drops, for example from temperature level 3 to temperature level 2, the second camera sharing service can increase the bitrate from 2.5Mbps to 5Mbps.

[0174] In another possible implementation of increasing the bitrate, after the second camera sharing service increases the bitrate to 2 / 3 of the base bitrate, if the shell temperature does not rise within a second preset time period, the second camera sharing service can increase the bitrate to the base bitrate.

[0175] For example, with a base bitrate of 5Mbps, a current bitrate of 2.5Mbps, and a second preset time period of 3 minutes, if the temperature level decreases, for example from temperature level 3 to temperature level 2, the second camera sharing service can increase the bitrate from 2.5Mbps to approximately 3.3Mbps. If the casing temperature does not rise within 3 minutes, then after 3 minutes, the second camera sharing service can increase the bitrate from 3.3Mbps to 5Mbps.

[0176] It is understood that the temperature control method in this application embodiment can increase the frame rate first, and then increase the bit rate. This is because when the frame rate increases, the bit rate also increases accordingly, so it is not necessary to increase the bit rate at the same time as increasing the frame rate. If both the frame rate and the bit rate are increased simultaneously, the phone temperature may rise more quickly. Of course, the temperature control method in this application embodiment can also increase the frame rate and bit rate simultaneously, or increase the bit rate first and then increase the frame rate; there is no limitation.

[0177] After the second camera sharing service increases the frame rate and / or bit rate, the second virtualization service can increase the encoder load and the amount of data transmitted. As a result, the frame rate and bit rate of the image data received by the computer side also increase, thereby improving the user experience.

[0178] It is understandable that when the second camera sharing service obtains a temperature level of 3 again, the above cooling strategy can be re-executed, which will not be elaborated further.

[0179] In summary, the embodiments of this application can adaptively adjust the frame rate of the camera capturing images and the bit rate of the electronic device transmitting images based on the baseline frame rate, baseline bit rate, temperature level, etc., without significantly affecting the user experience, thereby adjusting the temperature of the electronic device and reducing the probability of the electronic device overheating.

[0180] The methods of this application will be described in detail below through specific embodiments. The following embodiments can be combined with each other or implemented independently, and the same or similar concepts or processes may not be described again in some embodiments.

[0181] Figure 8 A temperature control method according to an embodiment of this application is illustrated. The method includes:

[0182] S801, The first electronic device calls the camera device of the second electronic device.

[0183] In this embodiment, the first electronic device and the second electronic device can be the same type of device or different types of devices. For example, the first electronic device may include the aforementioned... Figure 1 In the corresponding embodiment, the computer 100 and the second electronic device may include the aforementioned Figure 1 In the corresponding embodiment, the mobile phone 101 and the second electronic device may also include a tablet or other electronic devices. This application embodiment does not limit the first electronic device and the second electronic device.

[0184] S802, The second electronic device uses a camera device to capture images and transmits the images to the first electronic device.

[0185] In this embodiment of the application, the process of the second electronic device transmitting an image to the first electronic device can be referred to the above. Figure 7 The relevant descriptions in the corresponding embodiments will not be repeated here.

[0186] S803. During the process of the second electronic device acquiring images using the camera device, when the temperature of the second electronic device rises to a first preset value, if the first frame rate of the image acquired by the camera device is greater than the target frame rate, the second electronic device reduces the frame rate of the image acquired by the camera device; otherwise, if the first frame rate is less than or equal to the target frame rate, the second electronic device reduces the bit rate of the transmitted image.

[0187] In this embodiment, the first preset value can be understood as a value indicating a relatively high temperature of the second electronic device. For example, the first preset value can be understood as the aforementioned... Figure 7 In the corresponding embodiment, the temperature range value corresponding to temperature level 3 can also be understood as the temperature range value corresponding to level 4, without limitation.

[0201] Although the fourth temperature is higher than the second temperature, causing the temperature of the second electronic device to rise, the second electronic device does not need to reduce its frame rate because both the fourth and second temperatures fall within the same preset temperature range.
