Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.

Currently, a camera device (may also be referred to as a camera device) is generally included on a notebook computer, so that a user may take a picture using the camera device on the notebook computer, for example, the user may take a picture, record a video, or perform a video conference using the camera device on the notebook computer.

When a user uses a camera device on a notebook computer to take a picture, the user may also process the image taken by the camera device to obtain a final image using different effect algorithms, where an effect algorithm refers to an algorithm that processes an image frame (which may also be referred to as an image). The effect algorithm may also be referred to as an image algorithm, i.e. an algorithm used when processing an image taken by the camera device. For example, image algorithms may include algorithms for denoising images, image transformation, image analysis, image compression, image enhancement, image blurring processing, and the like. The image algorithm may also include an algorithm that performs a filter process, a beauty process, or a background process that masks an image captured by the camera device. That is, different image algorithms may implement different functions.

When a user uses a camera device on a notebook computer to shoot and uses an effect algorithm to process a shot image, the notebook computer generally sets the frequency of a CPU of the notebook computer according to a default power consumption strategy, namely a preset power consumption strategy in an operating system of the notebook computer.

However, the CPU frequency of the default power consumption policy setting is generally high, and the CPU frequency is high, which results in a larger power consumption of the CPU. And because the notebook computer uses the effect algorithm to further process the image, the load of the CPU is higher, and the power consumption is larger.

In addition, when a user uses a camera device on a notebook computer to shoot and uses an effect algorithm to process a shot image, the CPU of the notebook computer does not need to be high in frequency, and the CPU frequency of the notebook computer is high according to a default power consumption strategy, so that the CPU resource is wasted.

In the related art, a notebook computer can identify whether a user uses an effect algorithm to shoot when shooting by using camera equipment on the notebook computer by setting a hook function. And further, under the condition that the notebook computer recognizes that a user shoots by using an effect algorithm, the notebook computer can perform corresponding power consumption adjustment.

In the related art, a hook function needs to be set in a notebook computer, so that when a user shoots by using an effect algorithm on the notebook computer, the notebook computer can call the hook function first and then call the effect algorithm. That is, the notebook computer can determine whether the user uses the effect algorithm on the notebook computer to take a photograph by determining whether the hook function is called.

However, in this related art, it is necessary to provide a hook function in a notebook computer. In general, a procedure of setting a hook function is complicated, which results in a complicated procedure of recognizing whether a user uses an effect algorithm on a notebook computer to photograph. When the hook function is set in the notebook computer, the hook function is usually set in an operating system of the notebook computer. The addition of the hook function to the operating system of the notebook computer results in reduced security of the operating system of the notebook computer.

In view of the above problems, an embodiment of the present application provides a power consumption control method, which should be used in an electronic device, where the method may obtain a data stream start event when the electronic device starts a data stream of a camera (i.e. starts a camera device), and obtain an effect starting algorithm event when the electronic device starts an effect algorithm, and accurately identify whether the electronic device starts the effect algorithm to shoot by identifying the data stream start event and the effect starting algorithm event. When the electronic equipment is identified to start the effect algorithm to shoot, the electronic equipment can determine a corresponding power consumption adjustment strategy, and the frequency of a processor of the electronic equipment is correspondingly adjusted. According to the determined power consumption adjustment strategy, the electronic equipment can set the frequency of the processor of the electronic equipment to be smaller when adjusting the frequency of the processor of the electronic equipment, for example, the frequency of the processor of the electronic equipment can be set to be smaller than the frequency of the CPU corresponding to the default power consumption strategy, so that the power consumption of the CPU of the notebook computer can be reduced when a user shoots by using an effect algorithm on the notebook computer.

According to the scheme, when the electronic equipment starts the camera data stream, the event viewer included in the operating system of the electronic equipment reports a data stream starting event, and when the electronic equipment starts the effect algorithm, the event viewer included in the operating system of the electronic equipment reports the effect algorithm starting event, that is, the scheme can determine whether the electronic equipment starts the effect algorithm or not by using the event viewer in the operating system of the electronic equipment, a hook function is not required to be added in the operating system of the electronic equipment, the process of identifying whether shooting is performed by using the effect algorithm or not by the electronic equipment can be simplified, and the safety reduction of the operating system of the electronic equipment can be avoided.

In other examples, the electronic device may be an electronic device that includes an event viewer, e.g., a Windows system of the electronic device may include an event viewer.

In other examples, the electronic device may include an effects algorithm customization library. The effects algorithm customization library may include a plurality of effects algorithms. For example, the effect algorithm customization library may include algorithms for denoising an image, image transformation, image analysis, image compression, image enhancement, image blurring processing, and the like, and the effect algorithm customization library may also include filtering an image captured by a camera device, beautifying or obscuring the background of the image, and the like.

It will be understood, of course, that the above illustration of fig. 1 is merely exemplary of the case where the electronic device is in the form of a notebook computer. If the electronic device is in the form of a handheld computer, PDA, personal computer, or other device, the electronic device may include fewer structures than those shown in fig. 1, or may include more structures than those shown in fig. 1, and is not limited thereto.

The methods in the following embodiments may be implemented in an electronic device having the above-described hardware structure. In the embodiment of the application, the electronic equipment is taken as a notebook computer as an example for schematic description.

It will be appreciated that in general, implementation of electronic device functions requires software in addition to hardware support.

For example, in conjunction with fig. 2, in order to realize a function of accurately identifying whether the electronic device has turned on the effect algorithm to perform shooting, the electronic device needs to support hardware as described above, and also needs software, such as the camera application 01 and the perception application 02.

The camera application 01 may be used to obtain a data stream sent by a camera device of the electronic device. That is, when the electronic device starts up the camera device, the camera device may acquire a data stream (e.g., data corresponding to a captured picture, data stream corresponding to a captured video, etc.). After the camera device acquires the data stream, the camera device transmits the data stream to the camera application 01, so that the camera application 01 can display the data stream transmitted by the camera device.

It should be noted that, when the user uses the camera device of the electronic device and uses the effect algorithm to perform shooting, the camera device of the electronic device may first acquire a data stream (such as data corresponding to a shot picture, a data stream corresponding to a shot video, etc.).

After the camera device of the electronic device acquires the data stream, the electronic device may process the data stream acquired by the camera device using a corresponding effect algorithm, such as denoising or beautifying the data stream acquired by the camera device.

After the electronic device acquires the processed data stream, the electronic device may send the processed data stream to the camera application 01, so that the camera application 01 may display the processed data stream using the effects algorithm.

The aware application 02 may be configured to perceive a data stream sent by the camera device of the electronic device to the camera application 01, thereby determining whether the electronic device is capturing using an effects algorithm. For example, when the user uses the camera device of the electronic device to take a picture, the camera device of the electronic device may send the acquired data stream to the camera application 01 without using the effect algorithm, and the sensing application 02 may determine that the data stream sent by the camera device of the electronic device to the camera application 01 is a data stream that is not processed by the effect algorithm, so that the sensing application 02 may determine that the electronic device does not use the effect algorithm to take a picture.

For another example, when a user uses a camera device of the electronic device and uses an effect algorithm to shoot, the electronic device uses the corresponding effect algorithm to process a data stream acquired by the camera device, so as to acquire the processed data stream. After the electronic device acquires the processed data stream, the electronic device sends the processed data stream to the camera application program 01, and the sensing application program 02 can determine that the data stream sent to the camera application program 01 by the camera device of the electronic device is the data stream processed by the effect algorithm, so that the sensing application program 02 can determine that the electronic device uses the effect algorithm to shoot.

The aware application 02 may also be configured to determine a power consumption adjustment policy of the electronic device, and adjust power consumption of the electronic device according to the determined power consumption adjustment policy (e.g., adjust power consumption of a CPU of the electronic device). For example, when the sensing application 02 determines that the electronic device uses the effect algorithm to capture, the sensing application 02 may determine that the power consumption adjustment policy of the electronic device is a power consumption adjustment policy corresponding to the effect algorithm, and adjust the power consumption of the electronic device according to the power consumption adjustment policy corresponding to the effect algorithm. When the sensing application 02 adjusts the power consumption of the electronic device according to the power consumption adjustment policy corresponding to the usage effect algorithm, the frequency of the CPU of the electronic device may be set to a smaller frequency.

For another example, when the sensing application 02 determines that the electronic device does not use the effect algorithm to perform shooting, the sensing application 02 may determine that the power consumption adjustment policy of the electronic device is a power consumption adjustment policy corresponding to the effect algorithm, and adjust the power consumption of the electronic device according to the power consumption adjustment policy corresponding to the effect algorithm.

In some examples, in order for the aware application 02 to implement the function of determining whether the electronic device is shooting using the effects algorithm, and to implement the function of determining a power consumption adjustment policy of the electronic device, and adjusting the power consumption of the electronic device according to the determined power consumption adjustment policy, the aware application 02 needs to cooperate with different functional modules in addition to the hardware support as shown in fig. 1.

For example, as shown in connection with fig. 3, the aware application 02 also requires coordination of different functional modules such as a camera status probe 03, a probe manager 04, a scene awareness module 05, a scene policy management module 06, and a CPU power consumption scheduler 07.

The camera status probe 03 may be used to obtain the status of the camera device of the electronic device. That is, the camera status probe 03 may be used to obtain events during use of the camera device of the electronic device, such as a data stream start event (i.e., an event in which the camera device of the electronic device is started and begins to send a data stream to the camera application 01), an on-effects algorithm event (i.e., an event in which the electronic device uses effects algorithms to take a photograph), and a data stream off event (i.e., an event in which the camera device of the electronic device is off and stops sending a data stream to the camera application 01).

The camera status probe 03 may also be configured to send the acquired event during use of the camera device of the electronic device to the probe manager 04.

The probe manager 04 may be configured to receive an event during use of the camera device of the electronic device sent by the camera status probe 03. The probe manager 04 may also be configured to send the received event during use of the camera device of the electronic device to the scene sensing module 05.

The scene perception module 05 may be configured to receive an event during use of a camera device of the electronic device sent by the probe manager 04.

The scene perception module 05 may be further configured to determine different scenes (such as an effect algorithm on scene, an effect algorithm off scene, or a data stream off scene) according to an event during use of the camera device of the electronic device, that is, determine whether the electronic device uses the effect algorithm to shoot, or determine whether the camera device of the electronic device is turned off.

The scene perception module 05 may be further configured to send an effect algorithm start notification to the scene policy management module 06 when it is determined that the electronic device shoots using the effect algorithm.

The scene perception module 05 may be further configured to send a data stream shutdown notification to the scene policy management module 06 when it is determined that the electronic device does not use the effect algorithm to shoot.

The scene policy management module 06 may be configured to receive a notification (such as an effect algorithm on notification, an effect algorithm off notification, or a data stream off notification) sent by the scene perception module 05.

The scene policy management module 06 may be further configured to determine a corresponding power consumption adjustment policy according to the received notification sent by the scene sensing module 05. For example, in a case where the notification received by the scene policy management module 06 and sent by the scene perception module 05 is an effect algorithm on notification (corresponding to an effect algorithm on scene), the scene policy management module 06 may determine that the power consumption adjustment policy is a power consumption adjustment policy corresponding to the use effect algorithm. In the case that the notification sent by the scene perception module 05 and received by the scene policy management module 06 is an effect algorithm closing notification (corresponding to the effect algorithm closing scene), the scene policy management module 06 may determine that the power consumption adjustment policy is a power consumption adjustment policy corresponding to the closing effect algorithm. In the case where the notification sent by the scene perception module 05 and received by the scene policy management module 06 is a data stream shutdown notification (corresponding to a data stream shutdown scene), the scene policy management module 06 may determine that the power consumption adjustment policy is a power consumption adjustment policy corresponding to the non-usage effect algorithm.

The scenario policy management module 06 may be further configured to send a corresponding power consumption adjustment policy to the CPU power consumption scheduler 07.

The CPU power consumption scheduler 07 may be configured to receive the power consumption adjustment policy sent by the scene policy management module 06.

The CPU power consumption scheduler 07 may also be configured to adjust power consumption of the electronic device (e.g., adjust power consumption of a CPU of the electronic device) according to the power consumption adjustment policy sent by the received scene policy management module 06.

It should be noted that the sensing application 02 may also include other probes for sensing other scenes. For example, as shown in connection with fig. 3, the aware application 02 may also include an application type probe 08 for sensing the type of application that the electronic device is open to determine other scenarios.

In some examples, as shown in connection with fig. 4, in order for the camera status probe 03 to implement the functionality of acquiring events during use of the camera device of the electronic device, in addition to the support of hardware as shown in fig. 1 above, coordination of the camera service 09, the camera driver 11, the camera device 12, the event viewer 13, and the camera application 01 comprised by the electronic device is required. The camera service 09 can include an effects algorithm customization library 10. The effects algorithm customization library 10 may include a plurality of effects algorithms.

For example, as shown in connection with fig. 3 and 4, the process of acquiring events (such as the above-described data stream start event, the on-effect algorithm event, and the data stream off event) during use of the camera device of the electronic device by the camera status probe 03 may include the following processes.

The process of the camera status probe 03 acquiring a data stream start event may include:

when a user needs to take a picture using the camera device of the electronic device, the user may trigger the camera application 01 on the electronic device. That is, when the camera application 01 on the electronic device receives a trigger operation by the user, the camera application 01 on the electronic device may call the camera service 09 of the electronic device. After the camera application 01 on the electronic device invokes the camera service 09 of the electronic device, the camera service 09 of the electronic device may invoke the camera driver 11 of the electronic device.

After the camera service 09 of the electronic device invokes the camera driver 11 of the electronic device, the camera driver 11 of the electronic device may invoke the camera device 12 of the electronic device. In some examples, the camera driver 11 of the electronic device may invoke the camera device 12 of the electronic device through a USB interface or MIPI interface.

After the camera driver 11 of the electronic device invokes the camera device 12 of the electronic device, the camera device 12 of the electronic device is started. After the camera device 12 of the electronic device is started, the camera device 12 of the electronic device may acquire a data stream (e.g., data corresponding to a captured picture, data stream corresponding to a captured video, etc.).

After the camera device 12 of the electronic device acquires the data stream, the camera device 12 of the electronic device may send the acquired data stream to the camera driver 11 of the electronic device.

After the camera driver 11 of the electronic device receives the data stream, the camera driver 11 of the electronic device may send the data stream to the camera service 09 of the electronic device.

After the camera service 09 of the electronic device receives the data stream, the camera service 09 of the electronic device may send the data stream to the camera application 01 of the electronic device. After the camera application 01 of the electronic device receives the data stream, the electronic device may display the received data stream.

After the camera service 09 of the electronic device receives the data stream, the camera service 09 of the electronic device may also send a data stream start event to the event viewer 13 of the electronic device. That is, the camera status probe 03 of the electronic device has acquired the data stream start event. In some examples, where the operating system of the electronic device is a Windows system, the event viewer 13 may be a Windows event viewer.

After the electronic device's event viewer 13 receives the data stream start event, the electronic device event viewer 13 may send the data stream start event to the electronic device's aware application 02. In some examples, the electronic device event viewer 13 may send a data stream start event to the probe manager 04 included in the aware application 02 of the electronic device.

The process of the camera status probe 03 acquiring the on-effect algorithm event may include:

after the user triggers the electronic device to start the camera device (i.e. the camera status probe 03 acquires the data stream start event), when the user needs to use the effect algorithm of the electronic device to shoot, the user may trigger the effect algorithm displayed by the camera application 01 on the electronic device, so as to select a corresponding effect algorithm. That is, when the camera application 01 on the electronic device receives the triggering operation of the effect algorithm by the user, the camera application 01 on the electronic device may call the camera service 09 of the electronic device, so that the camera service 09 may process the data stream sent by the camera device 12 using the corresponding effect algorithm in the effect algorithm custom library 10.

After the camera application 01 on the electronic device invokes the camera service 09 of the electronic device, the camera service 09 of the electronic device can customize the library 10 with the effect algorithm to process the data stream sent by the camera device 12 using the corresponding effect algorithm.

After the camera service 09 of the electronic device processes the data stream sent by the camera device 12 using the corresponding effect algorithm in the effect algorithm customization library 10, the camera service 09 of the electronic device may send the processed data stream to the camera application 01 of the electronic device. After the camera application 01 of the electronic device receives the processed data stream, the electronic device may display the received processed data stream.

The camera service 09 of the electronic device may also send a number on effect algorithm event to the event viewer 13 of the electronic device when the camera service 09 of the electronic device processes the data stream sent by the camera device 12 using the corresponding effect algorithm in the effect algorithm customization library 10. That is, the camera status probe 03 of the electronic device has acquired the on-effect algorithm event.

After the electronic device's event viewer 13 receives the open effect algorithm event, the electronic device event viewer 13 may send the open effect algorithm event to the electronic device's aware application 02 4. In some examples, the electronic device event viewer 13 may send an open effect algorithm event to the probe manager 04 included in the aware application 02 of the electronic device.

The process of the camera status probe 03 acquiring a data stream shutdown event may include:

after the user triggers the electronic device to shoot using the effect algorithm (i.e. the camera status probe 03 acquires the event of turning on the effect algorithm), the user may trigger the camera application 01 on the electronic device when the user needs to turn off the camera device of the electronic device. That is, when the camera application 01 on the electronic device receives a trigger operation that the user turns off the camera device of the electronic device, the camera application 01 on the electronic device may invoke the camera service 09 of the electronic device.

After the camera application 01 on the electronic device invokes the camera service 09 of the electronic device, the camera service 09 of the electronic device may invoke the camera driver 11 of the electronic device.

After the camera service 09 of the electronic device invokes the camera driver 11 of the electronic device, the camera driver 11 of the electronic device may invoke the camera device 12 of the electronic device.

After the camera driver 11 of the electronic device invokes the camera device 12 of the electronic device, the camera device 12 of the electronic device is turned off.

When the camera application 01 on the electronic device invokes the camera service 09 of the electronic device, the camera service 09 of the electronic device may also send a data stream shutdown event to the event viewer 13 of the electronic device. That is, the camera status probe 03 of the electronic device has acquired a data stream shutdown event.

After the electronic device's event viewer 13 receives the data stream shutdown event, the electronic device event viewer 13 may send the data stream shutdown event to the electronic device's aware application 02. In some examples, the electronic device event viewer 13 may send a data stream shutdown event to the probe manager 04 included in the aware application 02 of the electronic device.

After the probe manager 04 receives the data stream start event, the start effect algorithm event or the data stream close event, the probe manager 04 may send the acquired data stream start event, start effect algorithm event or data stream close event to the scene sensing module 05, so that the scene sensing module 05 may determine a corresponding scene, and further, the scene policy management module may determine a corresponding power consumption policy according to the corresponding scene.

The power consumption control method provided by the embodiment of the application is described in detail below with reference to fig. 5. Fig. 5 is a flow chart of a power consumption control method according to an embodiment of the present application. As shown in fig. 5, the power consumption control method may include S501 to S538 described below.

That is, when the electronic device receives an operation of turning on the camera device by the user, the electronic device may turn on the camera device in response, and the operation of turning on the camera device by the user in the embodiment of the present application may be referred to as a fourth operation.

In some examples, when a user needs to take a photograph using a camera device of an electronic device, the user may trigger a camera application on the electronic device, such that the camera application of the electronic device may trigger the camera device of the electronic device to turn on. The process of triggering the camera device of the electronic device to be turned on by the camera application of the electronic device is as follows S502-S508.

In other examples, a user may initiate operation of the camera device by invoking a camera application during use of other applications of the electronic device. For example, a user may turn on the operation of the camera device while using the social application to conduct a video call. That is, the electronic device may receive an operation for turning on the camera device when the video call is made, and the application of the video call may call the camera application, that is, the camera application of the electronic device may receive an operation for the user to turn on the camera device, so that the camera application may turn on the camera device.

In other examples, the user may trigger an operation of opening a camera application of the electronic device, such as a click operation of an icon of the camera application by the user. After the user starts the camera device of the electronic device, the user can also operate the camera device of the electronic device to take a picture, and can also operate the camera device of the electronic device to record a video.

S502, in response to an operation of turning on the camera device by the user, the camera application of the electronic device sends a first notification to the camera service to instruct to turn on the camera device of the electronic device.

When a camera application of the electronic device receives an operation of turning on the camera device by a user, such as a click operation of an icon of the camera application by the user, the camera application of the electronic device may send a first notification to the camera service in response. The first notification may be used to indicate that the camera device of the electronic device is to be activated.

That is, after the camera application of the electronic device receives an operation of turning on the camera device by the user, the camera application of the electronic device may invoke the camera service, so that the camera service may send a first notification to the camera driver.

S503, the camera service of the electronic device receives the first notification.

S504, the camera service of the electronic device sends a second notification to the camera driver.

After the camera service of the electronic device receives the first notification sent by the camera application of the electronic device, the camera service of the electronic device may send a second notification to a camera driver of the electronic device to indicate that the camera device of the electronic device is activated.

I.e. the camera driver of the electronic device may invoke the camera device of the electronic device via a USB interface or MIPI interface.

S507, the camera device of the electronic device receives a third notification.

S508, starting the camera device of the electronic device.

After the camera device of the electronic device receives the third notification sent by the camera driver of the electronic device, the camera device of the electronic device may be started.

S509, the camera device of the electronic device acquires the data stream.

After the camera device of the electronic device is turned on, the camera device of the electronic device may acquire a data stream, which may also be referred to as a camera data stream. After the camera device of the electronic device acquires the data stream, the data stream may be sent to the camera application of the electronic device, so that the camera application of the electronic device may display the data stream sent by the camera device. The process of the camera device of the electronic device transmitting the data stream to the camera application of the electronic device is as follows S510-S515.

Camera data streams, i.e. data of images taken by a camera device of an electronic device. The data of the image shot by the camera device may be data corresponding to a picture shot by the camera device when shooting, may also be data corresponding to a picture shot by the camera device when recording, or may also be data corresponding to a picture shot by the camera device when making a video call.

It should be noted that, when the camera device of the electronic device is in the preview state, the camera device also acquires the camera data stream. The camera device of the electronic device obtains the data stream when the camera device of the electronic device is started, and sends the obtained data stream to the camera application program of the electronic device, that is, the operation that the user starts the camera device is the operation that the user starts the data stream of the camera device.

In the embodiment of the application, the operation of starting the camera equipment by the user is taken as an example for schematic description when the user uses the electronic equipment to carry out video call, namely, the data stream acquired by the camera equipment of the electronic equipment is the data corresponding to the picture shot by the camera equipment of the electronic equipment when carrying out video call.

It should be noted that, after the user turns on the camera device, the user operates the camera device of the electronic device to perform a video call, and the camera device of the electronic device may continuously acquire a data stream during the video call, that is, the camera device of the electronic device may continuously send the acquired data stream to the camera application program of the electronic device.

After the camera device of the electronic device acquires the data stream, the camera device of the electronic device may send the acquired data stream to a camera driver of the electronic device.

S511, the camera driver of the electronic device receives the data stream.

S512, the camera driver of the electronic device sends the data stream to the camera service.

After the camera driver of the electronic device receives the data stream sent by the camera device of the electronic device, the camera driver of the electronic device may send the received data stream to a camera service of the electronic device.

S513, the camera service of the electronic device receives the data stream.

S514, the camera service of the electronic device sends the data stream to the camera application.

After the camera service of the electronic device receives the data stream sent by the camera driver of the electronic device, the camera service of the electronic device may send the received data stream to a camera application of the electronic device.

S515, the camera application program of the electronic device receives and displays the image corresponding to the data stream.

After the camera application of the electronic device receives the data stream sent by the camera service of the electronic device, the camera application of the electronic device may display the first interface. The first interface may include an image corresponding to a data stream received by a camera application of the electronic device.

For example, taking an operation of starting the camera device by a user as an example of an operation of starting the camera device when the user uses the electronic device to perform video call, when the camera application program of the electronic device receives an operation of triggering the camera device of the electronic device to perform video call by the user, the camera application program of the electronic device starts the camera device of the electronic device by calling the camera service and the camera driver. After the camera device of the electronic device is started, the camera device of the electronic device acquires a data stream at the time of the video call (i.e., an image captured by the camera device at the time of the video call).

After the camera device of the electronic device acquires the data stream at the time of the video call, the camera device of the electronic device transmits the acquired data stream to the camera application of the electronic device through the camera driver and the camera service. After the camera application of the electronic device receives the data stream, the electronic device may display the received data stream, as shown in (a) in fig. 6A, when the electronic device performs a video call, the camera device of the electronic device may acquire an image captured during the video call, after the camera application of the electronic device receives the data stream, the electronic device may display a first interface (i.e., an interface for the video call), where the first interface may include an image corresponding to the data stream received by the camera application of the electronic device (i.e., an image captured by a camera of the electronic device).

The first interface may also include an effects algorithm control. When the user needs to use the effect algorithm to shoot, the user can trigger an effect algorithm control (which can be called as a first control in the embodiment of the application) included in the first interface. That is, when the electronic device receives a triggering operation, such as a clicking operation, of an effect algorithm control included in the first interface, the electronic device may use a corresponding effect algorithm (in the embodiment of the present application, may be referred to as a preset image algorithm, where the preset image algorithm corresponds to the first control), to process a data stream sent by the camera device to the camera application program.

In some examples, the effect algorithm control may be one or multiple, which is not limited in the embodiment of the present application. Different effect algorithm controls may correspond to different effect algorithms. For example, the effect algorithm control may include a filter option, a beauty option, an occlusion background option, a denoising option, a blurring option, and the like, where the filter option corresponds to a filter effect algorithm (i.e., when the user selects the filter option, the electronic device may filter an image captured by the camera device), the beauty Yan Xuanxiang corresponds to a beauty effect algorithm (i.e., when the user selects the beauty option, the electronic device may beautify an image captured by the camera device), the occlusion background option corresponds to an occlusion background effect algorithm (i.e., when the user selects the occlusion background option, the electronic device may occlude a background of an image captured by the camera device), the denoising option corresponds to a denoising effect algorithm (i.e., when the user selects the denoising option, the electronic device may denoise an image captured by the camera device), and the blurring option corresponds to a blurring effect algorithm (i.e., when the user selects the blurring option, the electronic device may blur an image captured by the camera device).

In some examples, the electronic device may select one effect algorithm to shoot, or the electronic device may select multiple effects to shoot at the same time, which is not limited by the embodiment of the present application.

For example, continuing to take the operation of turning on the camera device by the user, for example, as shown in (a) in fig. 6A, when the user uses the electronic device to perform a video call, the camera device of the electronic device may acquire an image captured during the video call, after the camera application of the electronic device receives the data stream, the electronic device may display a first interface (i.e., an interface for the video call), where the first interface may include the data stream received by the camera application of the electronic device (i.e., an image captured by the camera of the electronic device).

In the present application, a power consumption adjustment strategy is used to adjust the power consumption of an electronic device. In particular, it may be used to adjust the power consumption of a CPU on an electronic device. For example, the power consumption adjustment policy may adjust the power consumption of the CPU by adjusting relevant power consumption parameters of the CPU. For example, the power consumption parameter includes the frequency of the CPU, the energy efficiency ratio of the CPU, and the like.

In some examples, the first power consumption adjustment policy may include adjusting a frequency of a CPU of the electronic device to a first frequency.

In other examples, adjusting the frequency of the CPU of the electronic device to the first frequency may include adjusting an energy efficiency ratio of the CPU of the electronic device to the first energy efficiency ratio. The energy efficiency ratio is the ratio of performance to power consumption, i.e., the energy efficiency ratio is the ratio of energy conversion efficiency. The larger the energy efficiency ratio is, the more electric energy is saved, and the corresponding frequency of the CPU of the electronic equipment is reduced.

When the electronic equipment is identified to start the effect algorithm to shoot, the electronic equipment can determine a corresponding power consumption adjustment strategy, and the frequency of a processor of the electronic equipment is correspondingly adjusted. According to the application, when the frequency of the processor of the electronic device is regulated according to the corresponding power consumption regulation strategy, the frequency of the processor of the electronic device can be set to be smaller, for example, the frequency can be set to be smaller than the frequency of the CPU corresponding to the default power consumption strategy, so that the power consumption of the CPU of the notebook computer can be reduced when a user shoots by using an effect algorithm on the notebook computer.

In some examples, the second power consumption adjustment policy may include adjusting a frequency of a processor of the electronic device to a second frequency, which may be less than the first frequency (i.e., a frequency of a processor corresponding to the first power consumption adjustment policy). The second power consumption adjustment policy may also include adjusting an energy efficiency ratio of a CPU of the electronic device to a second energy efficiency ratio.
