Disclosure of Invention

According to the temperature control method and the temperature control device, when the temperature of the electronic equipment using the camera is increased, the frame rate of the image collected by the camera and the code rate of the image transmitted by the electronic equipment can be reduced, so that the temperature of the electronic equipment is not too high.

In a first aspect, a temperature control method provided in an embodiment of the present application includes: the first electronic device invokes a camera device of the second electronic device; the second electronic equipment collects images by using the camera device and transmits the images to the first electronic equipment; when the temperature of the second electronic equipment is increased to a first preset value in the process of acquiring images by the second electronic equipment by using the camera device, if the first frame rate of the images acquired by the camera device is larger than the target frame rate, the frame rate of the images acquired by the camera device is reduced by the second electronic equipment; otherwise, if the first frame rate is less than or equal to the target frame rate, the second electronic device reduces the code rate of the transmission image. Therefore, the frame rate of the image collected by the camera and the code rate of the image transmitted by the electronic equipment can be adaptively adjusted based on the reference frame rate, the reference code rate, the temperature grade and the like under the condition that the user experience is not affected basically, so that the temperature of the electronic equipment is adjusted, and the probability of overhigh temperature of the electronic equipment is reduced.

In a possible implementation, during the process of capturing the image by the second electronic device using the camera device: at a first moment, the temperature of the second electronic equipment is a first temperature, the frame rate of the image acquired by the camera device is a first frame rate, and the first frame rate is larger than the target frame rate; the temperature of the second electronic equipment is the second temperature, the frame rate of the image acquired by the camera device is the second frame rate, wherein the second time is later than the first time, the second temperature is higher than the first temperature, the second frame rate is lower than the first frame rate, and the second frame rate is higher than the target frame rate; the temperature of the second electronic equipment is a third temperature, the frame rate of the image acquired by the camera device is a third frame rate, the third temperature is later than the second time, the third temperature is higher than the second temperature, the third frame rate is lower than the second frame rate, and the third frame rate is higher than or equal to the target frame rate. Therefore, the effect of gradually reducing the frame rate can be realized, the descending amplitude of the frame rate is not large, the display effect of the interface is not too stuck, and the user experience can be not influenced as much as possible.

In a possible implementation, between the second time and the third time, the temperature of the second electronic device is a fourth temperature, and the frame rate at which the camera device collects the image is a second frame rate, where the fourth temperature is greater than the second temperature, the fourth temperature is less than the third temperature, and both the fourth temperature and the second temperature belong to the first preset temperature interval. In this way, frequent adjustments of the frame rate according to changes in temperature may not be required, so that the second electronic device may transmit images to the first electronic device at a relatively stable frame rate.

In one possible implementation, the temperature level corresponding to the first temperature is a first level, the temperature level corresponding to the second temperature is a second level, the temperature level corresponding to the third temperature is a third level, and the temperature level corresponding to the fourth temperature is a second level. Thus, the flow for executing frame rate adjustment is reduced, and the occupation of memory resources is reduced.

In a possible implementation, during the process of capturing the image by the second electronic device using the camera device: at a fourth moment, the temperature of the second electronic equipment is a fifth temperature, the frame rate of the image acquired by the camera device is a first frame rate, the code rate of the image transmitted by the second electronic equipment is a first code rate, and the first frame rate is larger than the target frame rate; the temperature of the second electronic equipment is the sixth temperature, the frame rate of the image acquired by the camera device is the target frame rate, and the code rate of the image transmitted by the second electronic equipment is the second code rate, wherein the fifth time is later than the fourth time, the sixth temperature is higher than the fifth temperature, and the second code rate is lower than the first code rate; at a sixth moment, the temperature of the second electronic equipment is a seventh temperature, the frame rate of the image acquired by the camera device is a target frame rate, the code rate of the image transmitted by the second electronic equipment is a third code rate, wherein the sixth moment is later than the fifth moment, the seventh temperature is higher than the sixth temperature, and the third code rate is lower than the second code rate. In this way, the second electronic device reduces the frame rate first and then reduces the code rate, and at this time, when the frame rate is reduced, the code rate is also reduced, so that the probability of the interface being stuck and/or blurred can be reduced.

In a possible implementation, between the fifth time and the sixth time, the temperature of the second electronic device is an eighth temperature, the frame rate at which the camera device collects the image is a target frame rate, and the code rate at which the second electronic device transmits the image is a second code rate, where the eighth temperature is greater than the sixth temperature, the eighth temperature is less than the seventh temperature, and both the eighth temperature and the sixth temperature belong to a second preset temperature interval. In this way, frequent adjustments of the code rate according to changes in temperature may not be required, so that the second electronic device may transmit images to the first electronic device at a relatively stable code rate.

In a possible implementation, during the process of capturing the image by the second electronic device using the camera device: at a seventh moment, the temperature of the second electronic equipment is a ninth temperature, the frame rate of the image acquired by the camera device is a first frame rate, the code rate of the image transmitted by the second electronic equipment is a first code rate, and the first frame rate is smaller than or equal to the target frame rate; the temperature of the second electronic equipment is tenth temperature, the frame rate of the image acquired by the camera device is the target frame rate, and the code rate of the image transmitted by the second electronic equipment is fourth code rate, wherein the eighth time is later than the seventh time, the tenth temperature is higher than the ninth temperature, and the fourth code rate is lower than the first code rate; at the ninth moment, the temperature of the second electronic equipment is eleventh temperature, the frame rate of the image acquired by the camera device is the target frame rate, the code rate of the image transmitted by the second electronic equipment is fifth code rate, wherein the ninth moment is later than the eighth moment, the eleventh temperature is higher than tenth temperature, and the fifth code rate is lower than the fourth code rate. Therefore, the descending amplitude of the code rate value is not large, the display effect of the interface is not too fuzzy, and the user experience can be not influenced as much as possible.

In a possible implementation, when the temperature of the second electronic device is reduced to the second preset value during the process of capturing the image by using the camera device, if the frame rate of capturing the image by using the camera device is smaller than the first frame rate, the second electronic device increases the frame rate. Therefore, the frame rate of the image acquired by the camera can be improved, and the image texture is improved.

In one possible implementation, a second electronic device increases a frame rate, comprising: the second electronic device increasing the frame rate to the first frame rate; or the second electronic equipment increases the frame rate to a fourth frame rate, the fourth frame rate is smaller than the first frame rate, and when the temperature of the second electronic equipment is reduced to a third preset value, the second electronic equipment increases the fourth frame rate to the first frame rate, and the third preset value and the second preset value belong to different temperature intervals; alternatively, the second electronic device increases the frame rate to a fourth frame rate; and when the temperature of the second electronic equipment is less than or equal to a second preset value in the first preset time period, the second electronic equipment increases the fourth frame rate to the first frame rate. Therefore, after the frame rate of the second electronic device is increased, the frame rate of the image data received by the first electronic device is also increased, so that the user experience is improved.

In a possible implementation, in the process that the second electronic device collects the image by using the camera device, when the temperature of the second electronic device is reduced to a fourth preset value, if the code rate of the image transmitted by the second electronic device is smaller than the first code rate, the second electronic device increases the code rate. Therefore, the code rate of the image acquired by the camera can be improved, and the image texture is improved.

In one possible implementation, a second electronic device increases a code rate, comprising: the second electronic device increases the code rate to the first code rate; or the second electronic equipment increases the code rate to a sixth code rate, the sixth code rate is smaller than the first code rate, when the temperature of the second electronic equipment is reduced to a fifth preset value, the second electronic equipment increases the sixth code rate to the first code rate, and the fifth preset value and the fourth preset value belong to different temperature intervals; or the second electronic equipment increases the code rate to the sixth code rate, and when the temperature of the second electronic equipment is smaller than or equal to the fourth preset value in the second preset time period, the second electronic equipment increases the sixth code rate to the first code rate. Therefore, after the second electronic equipment improves the code rate, the code rate of the image data received by the first electronic equipment is improved, so that the user experience is improved.

In a possible implementation, before the first electronic device invokes the camera device of the second electronic device, the method further includes: the first electronic device displays an interface of the target application, wherein the interface comprises identifications of one or more cameras; the identification of the one or more cameras comprises the identification of a camera device of the second electronic equipment; the first electronic device invokes a camera device of the second electronic device, comprising: the first electronic device invokes the camera device of the second electronic device in response to a selected operation of the identification of the camera device of the second electronic device.

The second electronic device may implement a photographing function through the ISP, the camera 293, the video codec, the GPU, the display 294, the application processor, and the like.

It will be appreciated that some of the specific details presented above with respect to the first electronic device and the second electronic device may not be required, and that the specific structures of the first electronic device and the second electronic device are not limited by the embodiments of the present application.

In this embodiment of the present application, the first electronic device and the second electronic device may use the same operating system, or may use different operating systems, where the operating systems may include any of the following operating systems, for example: linux operating system, unix operating system, android operating system, iOS operating system or windows operating system, etc.

Fig. 5 illustrates a part of the software architecture of the electronic device by using the Android system as the software system of the second electronic device. The software system may employ a layered architecture, an event driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture.

The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into five layers, from top to bottom, an application layer, an application framework layer, an Zhuoyun row (Android run) and system libraries, a hardware abstraction layer, and a kernel layer, respectively.

The application layer may include a series of application packages. The application packages may include applications for telephones, music, calendars, cameras, games, memos, videos, and the like. Applications may include system applications and three-way applications.

The application framework layer provides an application programming interface (application programming interface, API) and programming framework for application programs of the application layer. The application framework layer includes a number of predefined functions.

The application framework layer may include a window manager, resource manager, notification manager, content provider, and view system, among others. In the embodiment of the application program framework layer, the application program framework layer can further comprise a shared camera service, a temperature control service, a virtualization service, a communication service and the like.

The window manager is used for managing window programs. The window manager may obtain the display screen size, determine if there is a status bar, lock screen, touch screen, drag screen, intercept screen, etc.

The resource manager provides various resources for the application program, such as localization strings, icons, pictures, layout files, video files, and the like.

The content provider is used for realizing the function of data sharing among different application programs, allowing one program to access the data in the other program, and simultaneously ensuring the safety of the accessed data.

The view system may be responsible for interface rendering and event handling for the application.

The shared camera service may be used to perform camera related business processes, e.g., the shared camera service may interact with the communication service in signaling, e.g., signaling to start or shut down the camera; the shared camera service may also perform camera enablement through the virtualization service, synchronize camera status, and so on.

The temperature control service may provide a temperature change interface that may call back the temperature and/or temperature level of the electronic device when the temperature level of the electronic device changes. The temperature control service may also be referred to as a temperature control service.

The virtualization service can be used for realizing the call of cameras among devices, and can also be used for adjusting the frame rate of images acquired by the cameras and the code rate of images transmitted by the electronic device according to temperature adjustment information issued by the shared camera service. The virtualization service may also communicate camera data and signaling with the communication service.

The communication service can transmit camera data between two devices, for example, the camera data can comprise a frame rate of images acquired by a camera, a code rate of images transmitted by electronic devices, contents shot by the camera and the like; the communication service may also interact with the shared camera service and/or the virtualization service in signaling, e.g., the communication service may interact with the shared camera service in signaling including camera startup or shutdown, etc., and the communication service may interact with the virtualization service in signaling including parameter negotiation, etc.

Android runtimes include core libraries and virtual machines. Android run time is responsible for scheduling and management of the Android system.

The core library consists of two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

The application layer and the application framework layer run in a virtual machine. The virtual machine executes java files of the application program layer and the application program framework layer as binary files. The virtual machine is used for executing the functions of object life cycle management, stack management, thread management, security and exception management, garbage collection and the like. For example, in the embodiment of the present application, the virtual machine may be used to perform functions of turning on or off the camera, detecting the temperature of the electronic device, and adjusting the frame rate of the image acquired by the camera and/or the code rate of the image transmission.

The system library may also be referred to as Native layer, which may include a plurality of functional modules. For example: media libraries (media libraries), function libraries (function libraries), graphics processing libraries (e.g., openGL ES), etc.

Media libraries support a variety of commonly used audio, video format playback and recording, still image files, and the like. The media library may support a variety of audio video encoding formats, such as: MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, etc.

The function library provides multiple service API interfaces for the developer, and is convenient for the developer to integrate and realize various functions quickly.

The graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like.

The hardware abstraction layer is a layer of abstracted structure between the kernel layer and the Android run. The hardware abstraction layer may be a package for hardware drivers that provides a unified interface for the invocation of upper layer applications.

The kernel layer is a layer between hardware and software. The kernel layer may include bluetooth drivers, wireless fidelity (wireless fidelity, wi-Fi) technology drivers, display drivers, camera drivers, audio drivers, battery drivers, central processor drivers, USB drivers, and the like.

It should be noted that, the embodiments of the present application are only illustrated by using an android system, and in other operating systems (such as Windows systems, IOS systems, etc.), the schemes of the present application can also be implemented as long as the functions implemented by the respective functional modules are similar to those of the embodiments of the present application.

For convenience of description, the embodiment of the application describes a temperature control method by taking a shared camera scene of a user using a mobile phone camera on a computer as an example.

The computer side may be referred to as a user, and the mobile phone side may be referred to as a used party. The user and the used party can each include various functional modules for realizing the shared camera, for example, the shared camera service, the virtualization service, the communication service, the temperature control service and the like.

For convenience of description, the shared camera service of the user will be referred to as a first shared camera service, the virtualized service of the user will be referred to as a first virtualized service, and the communication service of the user will be referred to as a first communication service. The shared camera service of the used party is referred to as a second shared camera service, the virtualized service of the used party is referred to as a second virtualized service, and the communication service of the used party is referred to as a second communication service.

Fig. 6 shows a diagram of the interaction of software modules between a computer and a cell phone.

The application program layer of the user can comprise three-party applications capable of video conference, and the user can select the camera of the user in a certain three-party application. Taking the example that the user selects the front-facing camera of the used party, when the user responds to the operation that the user opens the front-facing camera of the used party, the information of opening the front-facing camera of the used party can be transmitted to the first shared camera service in the application framework layer.

After the first shared camera service receives the information of opening the front-end camera of the user, on one hand, the first shared camera service can enable and synchronize states of the cameras of the user through the first virtualization service.

The camera enabling may include camera enabling of a user and camera enabling of a used user. The camera enabling can be understood as the identification and mounting of the first virtualization service to the camera, and when the first virtualization service identifies the camera of the user or the used party and mounts the camera to the user, the camera is described as having the used capability.

The first virtualization service may perform camera-enabled data transmission with the second virtualization service through a data channel established between the first communication service and the second communication service. When the second virtualization service successfully enables the camera, the second virtualization service can transmit information of the camera enabling success to the first virtualization service through a data channel between the first communication service and the second communication service, the first virtualization service can return callback information of the camera enabling success of a user to the first sharing camera service, and the first sharing camera service can return the callback information to the three-party application, so that an interface of the three-party application can display the camera of the user. For example, the camera of the used party displayed by the interface of the three-party application may include the front camera 204 of the handset and the rear camera 205 of the handset in fig. 2 described above.

The synchronization of the camera states can comprise state synchronization of camera enabling, and can also comprise state synchronization of camera opening, camera opening success, camera closing success and the like in the use process of the camera.

On the other hand, the first shared camera service may perform transmission of control signaling with the first communication service, where the control signaling may include selecting a front or rear camera, turning on or off the camera, and so on. For example, the first shared camera service may pass information to the first communication service that opens the front-facing camera of the party being used.

The first communication service may transmit camera data between the user and the user, and the first communication service may transmit information of opening the front camera of the user to the second communication service of the user through a bluetooth module or a Wi-Fi module of a hardware abstraction layer, and a bluetooth driver or a Wi-Fi driver of a kernel layer.

In the application framework layer of the used party, the second communication service can report information of opening the front-end camera of the used party to the second shared camera service, the second shared camera service can transmit the information to the second virtualization service, and the second virtualization service starts a camera driver by calling a camera enabling interface of the hardware abstraction layer. When the camera of the user is turned on, the second virtualization service may transmit a result of the camera being turned on to the second communication service through the second shared camera service.

The second communication service may perform transmission of camera data between the user and the used party, and return a result of the camera activation to the first communication service of the user. The first communication service can report the result to the first shared camera service, the first shared camera service can return the result to the three-party application, and the three-party application can display information such as icons, characters and the like started by the camera in the interface.

It can be appreciated that the second virtualization service may also transmit the result of camera activation to the second communication service, where the second communication service returns the result of camera activation to the first communication service. The first communication service may report the result of the camera start to the first virtualization service. That is, the transmission of the camera data and the interaction of the signaling may be performed between the first virtualization service and the first communication service without passing through the first shared camera service. The transmitted camera data may include a frame rate of an image acquired by the camera, a code rate of an image transmitted by a user, content photographed by the camera, and the like, and the interactive signaling may include parameter negotiation, camera selection, camera capability starting, and the like.

It will be appreciated that when a three-way application is started, the first shared camera service, the first virtualization service, the first communication service, the second virtualization service, the second communication service, etc. may start running, so that the camera of the user or the used party may be enabled. When the interface of the three-party application can see the camera icon and/or the camera text, the camera is enabled successfully, and the camera has the capability of being used. When the used party receives the information of opening the camera, the second shared camera service and the temperature control service can start to operate. In this way, the second shared camera service and the temperature control service start to operate again when the camera is used, so that the power consumption of a user can be saved.

When the used party receives the information of closing the camera, the second shared camera service and the temperature control service can stop running. In this way, the second shared camera service and the temperature control service operate when the camera is used, and power consumption of a used party can be saved. When the three-party application is closed, the first shared camera service, the first virtualization service, the first communication service, the second virtualization service, the second communication service, and the like may cease to operate.

The implementation flow of the temperature control method according to the embodiment of the present application is described below with reference to fig. 7. It should be noted that, the computer and the mobile phone perform data interaction based on the communication channel between the first communication service and the second communication service, and the implementation flow in fig. 7 does not temporarily reflect the interaction between the first communication service and the second communication service.

1. And starting the camera sharing service.

When a user uses the camera of the mobile phone in the three-party application of the computer, the three-party application can send information of using the camera to the mobile phone through the first camera sharing service, the first communication service and the like of the computer, and the mobile phone can start the second camera sharing service after receiving the information. The process of sending the information of using the camera to the mobile phone by the specific computer can refer to the description in the embodiment corresponding to fig. 6, and will not be repeated.

2. And reporting the camera initialization frame rate and the camera initialization resolution.

After the second camera sharing service is started, the three-party application can report the camera initialization frame rate and the camera initialization resolution to the first virtualization service through the first camera sharing service. It will be appreciated that different applications may correspond to different camera initialization frame rates and camera initialization resolutions.

The first virtualization service transmits the camera initialization frame rate and the camera initialization resolution to the second virtualization service based on a communication channel between the first communication service and the second communication service, and the second virtualization service can report the camera initialization frame rate and the camera initialization resolution to the second camera sharing service. It can be appreciated that the second camera sharing service may convert the camera initialization resolution into a camera initialization code rate, and further, the second camera sharing service may store the camera initialization frame rate and the camera initialization code rate for subsequent use. The initialization frame rate may be referred to as a reference frame rate or a base frame rate, and the initialization code rate may be referred to as a reference code rate or a base code rate.

Illustratively, the camera initialization frame rate may be 30 frames per second (fps), the camera initialization resolution may be 1080P, and the second camera sharing service may convert the camera initialization resolution to a camera initialization code rate, for example, the camera initialization code rate may be 5 megabits per second (Mbps).

3. Registering a temperature monitoring callback.

In order to timely adjust the frame rate of the image collected by the camera or the code rate of the image transmitted by the mobile phone when the temperature of the mobile phone is increased or decreased, the second camera sharing service can register the temperature monitoring callback interface with the temperature control service. When the temperature of the mobile phone shell changes, the second camera sharing service can acquire the temperature and/or the temperature grade of the mobile phone shell through the callback interface. In this embodiment of the present application, the temperature of the mobile phone shell may be understood as the surface temperature of the mobile phone, the temperature of the mobile phone shell may also be referred to as the shell temperature or the front shell temperature, the frame rate at which the camera collects the image may be referred to as the frame rate, and the code rate at which the image is transmitted by the mobile phone may be referred to as the code rate.

In the implementation of acquiring the shell temperature by the possible temperature control service, the temperature sensor of the mobile phone may report the shell temperature to the temperature control service, or the temperature control service may periodically call a relevant interface to detect the shell temperature, which is not limited in the embodiment of the present application.

It is understood that the temperature control service may adjust the corresponding temperature level according to different changes in temperature. For example, table 1 below may represent the correspondence of the shell temperature to the temperature level.

TABLE 1

Entry temperature	Back-off temperature	Temperature rating
			The shell temperature is 37 DEG C	The temperature of the front shell is 35 DEG C	1
The shell temperature is 40 DEG C	The temperature of the front shell is 38 DEG C	2
			The shell temperature is 43 DEG C	The temperature of the front shell is 41 DEG C	3
The shell temperature is 48 DEG C	The temperature of the front shell is 46 DEG C	4

The entry temperature is understood to mean that, when the shell temperature increases to a certain temperature, the corresponding temperature level also increases accordingly. For example, when the shell temperature increases to 37 ℃, the corresponding temperature level is 1, and when the shell temperature increases to 40 ℃, the corresponding temperature level increases to 2. When the shell temperature is less than 37 ℃, the corresponding temperature level is 0, and it can be understood that the temperature level 0 can be a default temperature level of the mobile phone.

The rollback temperature is understood to mean that when the shell temperature decreases to a certain temperature, the corresponding temperature level decreases accordingly. For example, when the shell temperature is reduced to 41 ℃, the corresponding temperature level is 2, that is, the shell temperature is backed off to a lower temperature level; similarly, when the shell temperature is reduced to 38 ℃, the corresponding temperature level is reduced to 1.

It may be understood that the entering temperature, the retreating temperature and the temperature level may be determined by the temperature control service in a self-defining manner, and the values of the entering temperature, the retreating temperature and the temperature level are not limited in this embodiment. In addition, the change in the shell temperature and the change in the temperature level may not be positively correlated, for example, the temperature level may be correspondingly reduced as the shell temperature increases, and the temperature level may be correspondingly increased as the shell temperature decreases. The specific shell temperature and temperature level changes are not limited in this application.

4. The temperature level 3 is recalled.

When the second camera sharing service obtains callback information of the temperature level 3, the corresponding shell temperature rises to 43 ℃, which indicates that the current temperature of the mobile phone is higher, and the user experience can be possibly affected. Thus, the second camera sharing service may initiate a temperature down policy of temperature level 3.

5. And starting a temperature grade 3 cooling strategy.

In possible implementations, the cooling policy may include (1) reducing the frame rate and/or (2) reducing the code rate.

(1) The frame rate is reduced.

The second camera sharing service may reduce the frame rate. Specifically, when the reference frame rate is greater than the preset minimum frame rate, the second camera sharing service may reduce the frame rate to 2/3 of the reference frame rate. If the temperature level continues to rise, the second camera sharing service may reduce the frame rate to 1/2 of the reference frame rate. Different electronic devices may have different preset minimum frame rate values, for example, the preset minimum frame rate may be 15fps, and the value of the preset minimum frame rate is not limited in the embodiment of the present application.

It should be noted that the reduced frame rate value must not be lower than the preset minimum frame rate, that is, if the reduced frame rate is smaller than the preset minimum frame rate, the second camera sharing service may set the frame rate to the preset minimum frame rate. In this way, the smoothness of the picture can be basically maintained, so that the user experience is not too bad.

Illustratively, taking the reference frame rate of 30fps and the preset minimum frame rate of 15fps as an example, the cooling strategy may be executed when the second camera sharing service obtains that the temperature level increases from the temperature level 2 to the temperature level 3. Since the reference frame rate is greater than the preset minimum frame rate, the second camera sharing service may reduce the frame rate to around 20 fps. If the temperature level continues to rise, after a rise from temperature level 3 to temperature level 4, the second camera sharing service may reduce the frame rate to around 15 fps.

(2) The code rate is reduced.

When the frame rate is less than or equal to the preset minimum frame rate, the second camera sharing service may reduce the code rate. Wherein the case where the frame rate is less than or equal to the preset minimum frame rate may include (a) the reference frame rate is less than or equal to the preset minimum frame rate; (b) The second camera sharing service reduces the frame rate to a preset minimum frame rate, etc.

(a) The reference frame rate is less than or equal to a preset minimum frame rate.

When the reference frame rate is less than or equal to the preset minimum frame rate, the second camera sharing service can keep the frame rate unchanged, and the code rate is reduced to 2/3 of the reference code rate. If the temperature level continues to rise, the second camera sharing service may reduce the code rate to 1/2 of the reference code rate.

Illustratively, taking the example that the reference frame rate is 15fps, the preset minimum frame rate is 15fps, and the reference code rate is 2.5Mbps, when the second camera sharing service obtains that the temperature level is increased from the temperature level 2 to the temperature level 3, the cooling strategy may be executed. Because the reference frame rate is equal to the preset minimum frame rate, the second camera sharing service can keep the frame rate unchanged, and the code rate is reduced to about 1.7 Mbps. If the temperature level continues to rise, after the temperature level rises from 3 to 4, the second camera sharing service may reduce the code rate to about 1.2 Mbps.

(b) The second camera sharing service reduces the frame rate to a preset minimum frame rate.

When the second camera sharing service reduces the frame rate to the preset minimum frame rate, but the temperature level continues to rise or the inner shell temperature continues to rise in the first preset time period, the second camera sharing service can keep the frame rate unchanged, and the code rate is reduced to 2/3 of the reference code rate. If the inner shell temperature continues to rise for the first preset time period, the second camera sharing service can reduce the code rate to 1/2 of the reference code rate. The first preset time period may be defined by the second camera sharing service, for example, the first preset time period may be 5 minutes, and the value of the first preset time period is not limited in this embodiment of the present application.

For example, taking the example that the reference frame rate is 30fps, the preset minimum frame rate is 15fps, the reference code rate is 5Mbps, the first preset time period is 5 minutes, when the temperature level is increased from the temperature level 3 to the temperature level 4, the second camera sharing service reduces the frame rate to 15fps, the code rate is correspondingly reduced due to the reduction of the frame rate, and therefore, the code rate can be reduced to about 2.5 Mbps. If the inner shell temperature continues to rise for 5 minutes, the second camera sharing service can reduce the code rate to about 1.7 Mbps. If the inner shell temperature is still rising for 5 minutes, the second camera sharing service can reduce the code rate to about 1.2 Mbps.

It may be understood that the above-mentioned second camera sharing service may reduce the frame rate to 2/3 or 1/2 of the reference frame rate, and reduce the code rate to 2/3 or 1/2 of the reference code rate may be set for an empirical value, and the second camera sharing service may also reduce the frame rate or the code rate to other values respectively.

The second camera sharing service reduces the frame rate to 2/3 of the reference frame rate, then to 1/2 of the reference frame rate, and/or the second camera sharing service reduces the code rate to 2/3 of the reference code rate, then to 1/2 of the reference code rate, so that the effect of gradually reducing the frame rate or the code rate can be realized, the frame rate value or the code rate value can not be greatly reduced, the display effect of the interface can not be too stuck and/or too fuzzy, and the user experience can be not influenced as much as possible.

Of course, the temperature control method of the embodiment of the present application may also implement reducing the frame rate to the minimum value once, for example, reducing the frame rate to 1/2 of the reference frame rate, and/or reducing the code rate to the minimum value once, for example, reducing the code rate to 1/2 of the reference code rate. The temperature control method of the embodiment of the application can also realize the reduction of the frame rate and the code rate for more times, without limitation.

In the above implementation, the code rate may be reduced when the frame rate can no longer be reduced. This is because when the frame rate is reduced, the code rate is also reduced, and thus it is not necessary to reduce the code rate while reducing the frame rate. If the frame rate is reduced and the code rate is reduced, the interface may have a large probability of a stuck and/or blurred display effect, and the user experience is poor.

Of course, the temperature control method of the embodiment of the present application may also achieve simultaneous reduction of the frame rate and the code rate, or reduce the code rate first and then reduce the frame rate, without limitation. After the second camera sharing service executes the cooling strategy, the second virtualization service can reduce the load of the encoder and the data transmission quantity, so that the frame rate and the code rate of the image data received by the computer are also reduced, and the temperature of the mobile phone can be reduced.

When the temperature of the mobile phone is reduced, the temperature control method can further improve the frame rate of the images collected by the camera and the code rate of the images transmitted by the mobile phone, and improve the image texture.

6. The temperature level 2 is recalled.

When the second camera sharing service obtains callback information with the temperature level falling back to 2, the corresponding shell temperature is reduced to 41 ℃, and the temperature of the mobile phone is not too high, so that the second camera sharing service can (1) improve the frame rate and/or (2) improve the code rate.

7. The temperature is reduced, and the frame rate and the code rate are improved.

(1) And the frame rate is improved.

The second camera sharing service may increase the frame rate if the second camera sharing service adopts a scheme of reducing the frame rate before increasing the frame rate.

In one possible implementation of increasing the frame rate, the second camera sharing service may first increase the frame rate to 2/3 of the reference frame rate, and if the temperature level continues to decrease, the second camera sharing service may increase the frame rate to the reference frame rate.

Illustratively, taking a reference frame rate of 30fps and a current frame rate of 15fps as an example, if the temperature level drops, for example, from temperature level 3 to temperature level 2, the second camera sharing service may increase the frame rate from 15fps to around 20 fps. If the temperature level continues to drop, from temperature level 2 to temperature level 1, the second camera sharing service may increase the frame rate from 20fps to 30fps.

In another possible implementation of frame rate boosting, the second camera sharing service may boost the frame rate to the reference frame rate at a time.

Illustratively, taking a reference frame rate of 30fps and a current frame rate of 15fps as an example, if the temperature level drops, for example, from temperature level 3 to temperature level 2, the second camera sharing service may increase the frame rate from 15fps to 30fps.

In yet another possible implementation of increasing the frame rate, the second camera sharing service may increase the frame rate to the reference frame rate if the inner shell temperature is not increased for a second preset period of time after increasing the frame rate to 2/3 of the reference frame rate. The second preset time period may be defined by the second camera sharing service, for example, the second preset time period may be 3 minutes, and the first preset time period and the second preset time period may be the same or different, where the value of the second preset time period in the embodiment of the present application is not limited.

Illustratively, taking the reference frame rate of 30fps, the current frame rate of 15fps, and the second preset time period of 3 minutes as an example, if the temperature level drops, for example, from the temperature level 3 to the temperature level 2, the second camera sharing service may increase the frame rate from 15fps to about 20 fps. If the shell temperature does not rise within 3 minutes, the second camera sharing service may increase the frame rate from 20fps to 30fps after 3 minutes.

(2) And the code rate is improved.

If the second camera sharing service adopts a scheme of reducing the code rate before the code rate is increased, the second camera sharing service can increase the code rate.

In one possible implementation of increasing the code rate, the second camera sharing service may increase the code rate to 2/3 of the reference code rate first, and if the temperature level continues to increase, the second camera sharing service may increase the code rate to the reference code rate.

For example, taking the reference code rate of 5Mbps and the current code rate of 2.5Mbps as an example, if the temperature level drops, for example, from the temperature level 3 to the temperature level 2, the second camera sharing service may increase the code rate from 2.5Mbps to about 3.3 Mbps. If the temperature level continues to drop, the second camera sharing service may increase the code rate from 3.3Mbps to 5Mbps after dropping from temperature level 2 to temperature level 1.

In another possible implementation of code rate promotion, the second camera sharing service may promote the code rate to the reference code rate at a time.

Illustratively, taking the reference code rate of 5Mbps and the current code rate of 2.5Mbps as an example, if the temperature level drops, for example, from the temperature level 3 to the temperature level 2, the second camera sharing service may increase the code rate from 2.5Mbps to 5Mbps.

In another possible implementation of increasing the code rate, after increasing the code rate to 2/3 of the reference code rate, the second camera sharing service may increase the code rate to the reference code rate if the inner shell temperature is not increased in the second preset time period.

For example, taking the reference code rate of 5Mbps, the current code rate of 2.5Mbps, and the second preset time period of 3 minutes as an example, if the temperature level is reduced, for example, from the temperature level 3 to the temperature level 2, the second camera sharing service may increase the code rate from 2.5Mbps to about 3.3 Mbps. If the shell temperature does not rise within 3 minutes, the second camera sharing service may increase the code rate from 3.3Mbps to 5Mbps after 3 minutes.

It can be understood that, in the temperature control method of the embodiment of the present application, the frame rate may be first increased, and then the code rate may be increased. This is because the code rate increases as the frame rate increases, so it is not necessary to increase the code rate at the same time as the frame rate increases. If the frame rate is increased while the code rate is increased, the temperature of the mobile phone may be increased faster. Of course, the temperature control method of the embodiment of the application may also implement raising the frame rate and the code rate simultaneously, or raise the code rate first and then raise the frame rate, without limitation.

After the frame rate and/or the code rate of the second camera sharing service are/is improved, the second virtualization service can increase the load of the encoder and the transmission data quantity, so that the frame rate and the code rate of the image data received by the computer are also improved, and the user experience is improved.

It can be understood that, when the second camera sharing service acquires the temperature level of 3 again, the above cooling policy may be executed again, which is not described again.

As can be seen from the above, according to the embodiment of the present application, under the condition that user experience is not substantially affected, the frame rate of the image collected by the camera and the code rate of the image transmitted by the electronic device are adaptively adjusted based on the reference frame rate, the reference code rate, the temperature level and the like, so that the temperature of the electronic device is adjusted, and the probability of overhigh temperature of the electronic device is reduced.

The method according to the embodiment of the present application will be described in detail by way of specific examples. The following embodiments may be combined with each other or implemented independently, and the same or similar concepts or processes may not be described in detail in some embodiments.

Fig. 8 shows a temperature control method of an embodiment of the present application. The method comprises the following steps:

s801, the first electronic device calls a camera device of the second electronic device.

In this embodiment of the present application, the first electronic device and the second electronic device may be the same type of device, or may be different types of devices. The first electronic device may include the computer 100 in the embodiment corresponding to fig. 1, the second electronic device may include the mobile phone 101 in the embodiment corresponding to fig. 1, and the second electronic device may also include a tablet or other electronic devices, which are not limited in this embodiment.

S802, the second electronic equipment collects images through the camera device and transmits the images to the first electronic equipment.
