Fig. 2 is a schematic diagram of an internal structure of an electronic device in one embodiment. As shown in fig. 2, the electronic device includes a processor, a memory, and a network interface connected by a system bus. Wherein, the processor is used for providing calculation and control capability and supporting the operation of the whole electronic equipment. The memory is used for storing data, programs and the like, and at least one computer program is stored on the memory, and the computer program can be executed by the processor to realize the method for adjusting the image display preview frame rate of the electronic device, which is suitable for the electronic device, provided by the embodiment of the application. The Memory may include a non-volatile storage medium such as a magnetic disk, an optical disk, a Read-Only Memory (ROM), or a Random-Access-Memory (RAM). For example, in one embodiment, the memory includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system and a computer program.

In the conventional technology, when an electronic device performs a video call, for an application in a white list on the electronic device, a frame rate range for image display preview of the video call is fixed, for example, an application in the white list limits a frame rate range for the image display preview frame rate to be 5 to 24fps (frame Per Second, frame Per Second, abbreviated as fps), while an application not in the white list has a frame rate range for the image display preview frame rate to be 10 to 30 fps. The scheme that the frame rate range of the image display preview frame rate of the electronic equipment is fixed has some defects: when a video component operates, such as video call, photography or camera shooting, the electronic device has more hardware resources involved in operation, and the problems of power consumption and heating are relatively outstanding, and if the frame rate range of the image display preview frame rate is fixed, the smoothness requirement of image display and the power consumption heating requirement of the electronic device cannot be better and dynamically adapted, for example, the frame rate range of the image display preview frame rate of an application in a white list is fixed at 5-24 fps, but in some scenes, the frame rate range of the image display preview frame rate is increased to 10-30 fps, even higher frame rate range, so that the smoothness requirement of the image display of the application and the effect requirement of the application can be met, for example, some instant communication software, such as WeChat, Skype software, imo chat and the like, can use the software of video call; on the contrary, in some application scenarios, the frame rate range of the image display preview frame rate is reduced, for example, the frame rate range of the image display preview frame rate of the application is reduced to 5-20 fps, so that a better power consumption heating performance of the electronic device can be obtained.
Based on this, the embodiment of the present application provides a method for adjusting an image display preview frame rate of an electronic device, where the electronic device can automatically dynamically adjust a frame rate range of the image display preview frame rate of the electronic device according to actual power consumption and heat generation performance, so as to obtain a better balance between fluency of image display and power consumption and heat generation of the electronic device.
Note that the preview frame rate and the display frame rate are different from each other, and the differences are as follows:
(1) when a preview refers to a representation of the field of cameras, in general, the output modes of the camera include: a preview output mode, a photographing mode and a recording mode.
The preview output mode refers to the screen content output by the camera, and after the screen content is processed by Image Signal Processing (abbreviated as ISP), the flow behind the software displays the screen stream on the screen.
The picture output mode refers to picture content output by the camera, and after the picture content is processed by the ISP, the picture content is coded and then stored in a file form by the later process of software to form a single picture file. Wherein, the photographing output mode may include a process of preview output.
The video output mode refers to the picture content output by the camera, and after the picture content is processed by the ISP, the following process of the software encodes the picture streams and stores the encoded picture streams in the form of a file to form a video file. The video output mode may include a preview output process.
The preview frame rate refers to a frame rate of a picture output by the camera in the preview output mode, for example, the preview frame rate is 30fps, which indicates that the camera outputs 30 pictures per second at this time, and application scenarios of the preview frame rate include: video calls, photography, or video capture.
(2) The display means that all pictures on the terminal are stored in a buffer area in the memory, when the pictures are updated, the electronic device refreshes the buffer area once, and then the display controller flushes the content of the buffer area to the screen.
Display frame rate: referring to the number of times the electronic device refreshes the buffer area per second, for example, the display frame rate is 60fps, which indicates that the electronic device refreshes the buffer area 60 times per second, and the application scenarios include: games or movie television, etc.
Referring to fig. 3, fig. 3 is a flowchart illustrating a method for adjusting an image display preview frame rate of an electronic device according to an embodiment of the present disclosure, where the method for adjusting the image display preview frame rate of the electronic device in the embodiment of the present disclosure is described by taking the electronic device in fig. 1 as an example. As shown in fig. 3, the method for adjusting the image display preview frame rate of the electronic device includes:
and step 302, acquiring power consumption characteristics and heating characteristics of the electronic equipment.
Specifically, the power consumption characteristics refer to power consumption performance of the electronic device, including current power consumption of the electronic device, and a charging state of the electronic device. Generally, the capacity of the electronic device is represented by a certain number of milliamperes, such as 2300 milliamperes and 3200 milliamperes, and the current capacity of the electronic device is represented by 80%, 50%, or 30% of the battery capacity. Here, the battery capacity indicates an amount of electricity discharged from the battery under a certain condition (such as a discharge rate, a temperature, and a voltage), that is, the capacity of the battery, and is generally expressed in units of ampere-hour (abbreviated as "a · H", 1A · H ═ 3600C), milliampere, which is a unit of measurement of current, and is expressed in letters mA, and one milliampere is one thousandth of one ampere. The Quantity of electricity (english Quantity of electric charge) indicates how much an object is charged, and generally, the Quantity of electric charge is called the Quantity of electricity, and is represented by symbol Q, and the unit is bin (symbol is C). The electronic device power consumption is in different states, for example, the electronic device is in a screen-off state and a screen-on state, the electronic device is in a standby state and a use state, the power consumed by the electronic device during operation is different, and the power consumed by different application programs during operation is also different, so that the power consumption of the electronic device changes with the change of the state of the electronic device and the difference of the running application programs, and the power consumption of the electronic device is generally expressed as the power of the electronic device and can be converted into the power consumed correspondingly. The charging state of the electronic device includes that the electronic device is being charged, that the electronic device is not being charged, and the like. The electronic equipment acquires the power consumption information of the electronic equipment, can acquire the power consumption information of the electronic equipment through a power supply (Powersupply), and can also acquire the power consumption information through a power consumption log provided by a battery state service (Battery).
The heating characteristic refers to the heating performance of the electronic device, and includes temperature information of each warm zone (Thermal _ zone) in the electronic device, including a Central Processing Unit (CPU) temperature, a Graphics Processing Unit (GPU) temperature, and a motherboard temperature (board temperature for short), where the highest temperature among the CPU temperature, the GPU temperature, and the motherboard temperature is the temperature of the electronic device. The CPU temperature, the GPU temperature and the mainboard temperature can be respectively obtained through temperature sensors, and the temperature ranges of the CPU temperature, the GPU temperature and the mainboard temperature are generally 30-60 ℃. The electronic equipment acquires the temperature information of the electronic equipment and can acquire the temperature information through the temperature sensors corresponding to the warm areas.
And 304, acquiring the power consumption heating state of the electronic equipment according to the power consumption characteristics and the heating characteristics.
Specifically, the electronic device presets different parameters for each condition according to the acquired power consumption characteristics, such as conditions of the electronic device, such as electric quantity, power consumption data of the electronic device, a charging state of the electronic device, and the like, and conditions of the heating characteristics, such as CPU temperature, GPU temperature, motherboard temperature, and the like, determines the state of each condition according to the preset different parameters, and acquires the power consumption heating state of the electronic device according to the state of each condition. For example, the following conditions are predetermined:
(1) if the electronic equipment is in the uncharged state, the electric quantity of the electronic equipment can be judged according to the preset electric quantity threshold value.
The electric quantity state of the electronic equipment can be divided into different electric quantity states according to the comparison between the preset electric quantity threshold value and the current electric quantity of the electronic equipment. For example, if the current power of the electronic device is greater than or equal to a preset power threshold, it is called a first power state, if the current power of the electronic device is less than the preset power threshold, it is called a second power state, and so on, for example, the power threshold is set to 30% of the battery capacity, if the current power of the electronic device is greater than or equal to 30% of the battery capacity, because the electric quantity of the electronic equipment is sufficient, the current electric quantity of the electronic equipment is judged to be in the first electric quantity state, if the current electric quantity of the electronic equipment is less than 30 percent of the battery capacity, because the electric quantity of the electronic equipment is lower than the preset threshold value, the current electric quantity of the electronic equipment is judged to be in a second electric quantity state, the battery capacity is 2300 milliamperes, 3200 milliamperes or 3800 milliamperes, different electronic devices are different in capacity, and different electric quantity thresholds need to be set according to the actual conditions of specific electronic devices. Furthermore, a plurality of preset electric quantity thresholds can be set, and electric quantity is correspondingly divided into a plurality of states.
If the electronic device is in a charging state, the state of charge of the electronic device may be disregarded because the rate of power consumption is less than the rate of charging the battery.
(2) The electronic device power consumption may be represented by electric power.
The electric power is the work done by current in unit time, called electric power, and is used for representing the physical quantity of consumed electric energy, and is represented by P, and the unit of the electric power is Watt (Watt), which is called Watt for short, and the symbol is W.
The power consumption state of the electronic device may be determined based on a preset electric power threshold. For example, an electric power less than a preset electric power threshold is referred to as a first power consumption state, and an electric power greater than or equal to the preset electric power threshold is referred to as a second power consumption state. Specifically, for example, when the electric power threshold is set to 1600 mW, if the electric power consumption of the electronic device is less than 1600 mW, the power consumption of the electronic device is determined to be in the first power consumption state, and if the electric power consumption of the electronic device is greater than or equal to 1600 mW, the power consumption of the electronic device is determined to be in the second power consumption state, where mW is mW and 0.001W is one thousandth of watt.
It should be noted that, the parameters of the real-time power consumption are different for different electronic devices. For example, the power consumption of the mobile terminal is different from that of a desktop computer, and the power consumption of the wearable device is different from that of the mobile terminal, so that different electric power thresholds, such as 1200 milliwatts, 2000 milliwatts, or 2400 milliwatts, need to be set according to actual conditions of different electronic devices.
(3) The heating characteristic of the electronic equipment takes the highest temperature among the CPU temperature, the GPU temperature and the mainboard temperature as the judgment basis of the heating characteristic of the electronic equipment.
The heating characteristics can be judged by setting a temperature threshold of the temperature of the electronic equipment, and the heating characteristics of the electronic equipment can be divided into a first temperature state, a second temperature state and the like according to a preset temperature threshold. For example, the temperature of the electronic device is smaller than or equal to the temperature threshold as a first temperature state, and is greater than the temperature threshold as a second temperature state. Typically, the CPU temperature, GPU temperature and motherboard temperature will be between 30 degrees celsius and 60 degrees celsius. The temperature threshold value for setting the temperature of the electronic equipment is 50 ℃, if the obtained CPU temperature, the GPU temperature and the mainboard temperature do not exceed 50 ℃, the temperature of the electronic equipment is judged to be in a first temperature state, and if one of the obtained CPU temperature, the GPU temperature and the mainboard temperature exceeds 50 ℃, the temperature of the electronic equipment is judged to be in a second temperature state.
The power consumption heating state of the electronic device is further determined according to the above determination of the states of the conditions, for example, in combination with the above examples of the conditions, the power consumption heating state of the electronic device can be determined as follows:
(1) if the electronic equipment is in the charging state, only if the power consumption of the electronic equipment is in the first power consumption state and the temperature of the electronic equipment is in the first temperature state, the power consumption heating state of the electronic equipment can be judged to be in the first state, and if not, the power consumption heating state of the electronic equipment is judged to be in the second state.
The power consumption heating state of the electronic equipment is in a first state, which indicates that the power consumption of the electronic equipment can be further improved to meet the requirement of the electronic equipment on power consumption during operation, and the power consumption heating state of the electronic equipment is in a second state, which indicates that the power consumption of the electronic equipment needs to be reduced to ensure a good working state of the electronic equipment.
(2) If the electronic equipment is in the uncharged state, only if the electric quantity of the electronic equipment is in the first electric quantity state, the power consumption of the electronic equipment is in the first power consumption state and the temperature of the electronic equipment is in the first temperature state, the power consumption heating state of the electronic equipment can be judged to be in the first state, otherwise, the power consumption heating state of the electronic equipment is judged to be in the second state.
It should be noted that the above examples are only for understanding the embodiments of the present application and are not intended to limit the technical solutions of the present application, and the technical solutions of the present application include more or less expressions than the above examples and are within the scope of the claims of the present application. For example, in the above embodiment, the data of each condition and the power consumption heating state of the electronic device may be previously corresponding to the acquired conditions such as the electric quantity data of the electronic device, the power consumption data of the electronic device, the charging state of the electronic device, and the like, and the temperature data including the CPU temperature, the GPU temperature, the motherboard temperature, and the like included in the heating characteristic, and the power consumption heating state of the electronic device may be directly determined according to the data of each condition, and the current power consumption heating state of the corresponding electronic device may also be acquired through a process of determining the state of each condition according to the different preset parameters of each condition without presetting different parameters for each condition.
And step 306, adjusting the frame rate range of the image display preview frame rate of the electronic equipment according to a preset rule according to the power consumption heating state.
Specifically, frame rate, english: the Frame rate is a measure for measuring the number of display Frames in units of Frames Per Second (Frame Per Second, fps) or Hertz (Hz).
The electronic equipment judges whether the frame rate range of the image display preview frame rate is increased or decreased or the frame rate range of the image display preview frame rate is maintained according to the acquired power consumption heating state of the electronic equipment. For example, if the power consumption heating state of the electronic device is determined to be in the first state, the frame rate range of the image display preview frame rate can be increased, so that the smoothness of image display is improved, and if the current power consumption heating state of the electronic device is determined to be in the second state, the frame rate range of the image display preview frame rate can be decreased, so that the power consumption of the electronic device is decreased, and the balance among the power consumption, the heating and the smoothness of image display of the electronic device can be better obtained by dynamically adjusting the frame rate range of the image display preview frame rate in the video call, photographing or photographing process, so that the working state of the electronic device is optimized, and the efficiency of video call, photographing or photographing is improved.
Further, referring to fig. 4, fig. 4 is a software architecture diagram in the adjustment method for the preview frame rate in an embodiment, and the operation principle of each module of the software architecture diagram shown in fig. 4 is as follows:
(1) the power supply (Powersupply) is used for acquiring power consumption information of electronic equipment, and can be realized by a coulomb meter arranged in a system under a general condition, wherein the coulomb meter, also called ampere-second meter, is a programmable digital electric meter, and adopts an advanced microprocessor to carry out intelligent control, and after an input signal is subjected to operation processing by a CPU, the input signal outputs the current battery capacity.
(2) The temperature control core (Thermal core) is used for acquiring temperature information of the electronic device, and generally, the system is divided into different warm-up areas (Thermal zones), such as a CPU warm-up area, a GPU warm-up area and a motherboard warm-up area, and each warm-up area (Thermal zone) has a corresponding temperature Sensor (Sensor) for measuring temperature information.
(3) The system comprises a virtual file system sysfs and a Daemon process (Daemon) located in a library of a local layer (Native layer) space, wherein the Daemon process (Daemon) comprises a Power consumption local Daemon process (Power Native Daemon) and a temperature control local Daemon process (Thermal Native Daemon), the Daemon process (Daemon) can access information data corresponding to a Power supply (Power supply) and a temperature control core (Thermal core) through the sysfs, and in the embodiment, the Daemon process (Daemon) acquires Power consumption information and temperature information through the virtual file system sysfs.
(4) A Power consumption local daemon process (Power native daemon) acquires and arranges Power consumption information of the electronic device, and ranks Power consumption levels according to a threshold, for example, the Power consumption levels are divided into a first Power consumption state and a second Power consumption state according to whether the Power consumption of the electronic device is greater than or equal to a preset Power consumption threshold. For example, if the power consumption of the electronic device is less than 1600 mw, it is referred to as a first power consumption state, and if the power consumption of the electronic device is greater than or equal to 1600 mw, it is referred to as a second power consumption state.
(5) A local temperature control daemon (Thermal native daemon) acquires and arranges temperature information of the electronic device, and classifies temperature levels according to a threshold, for example, the temperature levels are classified into a first temperature state and a second temperature state.
(6) Battery status services (batteries) for providing a battery consumption log.
(7) The power consumption monitoring service (Powermonitor services) dynamically outputs the target frame rate range according to the power consumption level of the electronic device, the temperature level of the electronic device, and a battery consumption log provided by the battery status service (batteries services). And the power consumption monitoring service (Powermonitor services) module is also responsible for application management of the white list, such as setting the white list, adding an application in the white list, deleting an application in the white list, or setting a preview frame rate range of an application in the white list.

When a user uses a third-party chat Application (APP for short) to perform video chat, if the APP is in a white list of the electronic device, a frame rate mode corresponding to the technical scheme of the embodiment of the present Application may be used. For the frame rate mode of the technical scheme of the application, the frame rate mode can be set in the following two ways:
(1) in the first mode, the user can select the video call frame rate through setting, battery, advanced and video call frame rate adjustment, and then through one of three options: a first frame rate mode, wherein in the first frame rate mode, the frame rate range is 15-30 fps; a "second frame rate mode", in which the frame rate range is 5-20 fps; in the "dynamic frame rate mode", the frame rate range is dynamically adjusted according to the power consumption performance and the heat generation performance of the electronic device.

and if the video assembly is detected to be started, acquiring the power consumption characteristic and the heating characteristic of the electronic equipment.
Specifically, the video component refers to an element capable of performing a video call, shooting or shooting, and the like, and includes a camera, a lens of a camera, and the like, for example, a camera of a mobile terminal, a camera of a wearable device, and the like, or a digital camera, a video camera, and the like.

and if the message of starting the video assembly is received, judging that the video assembly is started.
Specifically, the white list and the concept of the white list correspond to a "black list", and it is simply understood that the white list is a user who can pass through the setting, and users other than the white list cannot pass through the setting.
The electronic equipment can manage the application program through the white list by setting the white list, the application program in the white list uses a mode of dynamically adjusting the frame rate range, and the application program outside the white list does not use the mode of dynamically adjusting the frame rate range, so that the application program is better managed, particularly the application program with higher requirements on the power consumption and the fluency of the electronic equipment, such as the application program of video call type, the application program of photography camera type and other application programs with higher power consumption.

In an embodiment, please refer to fig. 8, fig. 8 is a flowchart illustrating a step of acquiring a power consumption heating state of an electronic device according to an embodiment, where the step of acquiring the power consumption heating state of the electronic device according to the power consumption feature and the heating feature includes:
step 802, acquiring a power consumption level corresponding to the power consumption feature according to the power consumption feature;
step 804, acquiring a temperature level corresponding to the heating feature according to the heating feature;
and 806, acquiring the power consumption heating state of the electronic equipment according to the power consumption level and the temperature level.
Specifically, the power consumption level refers to a power consumption level at which the electronic device divides the power consumption characteristics according to a preset threshold, and is used for indicating the power consumption degree of the electronic device in different situations.
The following two cases can be classified:
(1) and under the condition of charging the electronic equipment, dividing the power consumption characteristics into different levels according to the power consumption threshold of the electronic equipment.
Specifically, the power consumption characteristics may be divided into three levels according to different power consumption thresholds of the electronic device, the power consumption characteristics are divided into a first level when the power consumption of the electronic device is less than or equal to a first preset power consumption threshold, the power consumption characteristics are divided into a second level when the power consumption of the electronic device is greater than or equal to a second preset power consumption threshold, and the power consumption characteristics are divided into a third level when the power consumption of the electronic device is between the first preset power consumption threshold and the second preset power consumption threshold. For example, the power consumption is expressed by electric power, see table 1, for example, a first preset power consumption threshold is set to 1600 milliwatts, a second preset power consumption threshold is set to 2400 milliwatts, and the power consumption levels of the electronic device are divided into a first level, a second level and a third level, which respectively correspond to corresponding power consumption characteristics. Wherein 1600 milliwatts is equivalent to the electric power of 400 milliamperes current under 4 volts; 2400 milliwatts corresponds to an electrical power of 600 milliamps of current at 4 volts.
(2) Under the condition that the electronic equipment is not charged, the power consumption characteristics are divided into different levels according to the battery power and the power consumption threshold of the electronic equipment. For example, the power consumption level is classified into three levels according to the battery capacity as a percentage of the battery capacity and the difference between the power consumption thresholds. For example, the first preset charge threshold is set to be 30% of the battery capacity, the second preset charge threshold is set to be 50% of the battery capacity, and the power consumption is expressed as electric power, see table 1, according to the fact that the charge is greater than or equal to 50% of the battery capacity, the charge is between 30% of the battery capacity and 50% of the battery capacity, the charge is less than or equal to 30% of the battery capacity, the electric power of the electronic device is less than or equal to 1600 milliwatts, the electric power of the electronic device is between 1600 milliwatts and 2400 milliwatts, and the electric power of the electronic device is greater than or equal to 2400 milliwatts, the power consumption levels are divided into a first level, a second level and a third level, which correspond to the corresponding power consumption characteristics respectively.
The temperature level refers to a temperature level preset by the electronic device and is used for indicating the heating degree of the electronic device, and the heating features are divided into different levels according to a preset temperature threshold.
According to the difference of the temperature thresholds, the heating features can be divided into three levels, when the temperature of the electronic device is less than or equal to a first preset temperature threshold, the electronic device is divided into a first level, when the temperature of the electronic device is greater than or equal to a second preset temperature threshold, the electronic device is divided into a second level, and when the temperature of the electronic device is between the first preset temperature threshold and the second preset temperature threshold, the electronic device is divided into a third level. For example, referring to table 1, according to the difference between the temperature of the electronic device and the preset temperature threshold, the first preset temperature threshold is set to 35 degrees celsius, the second temperature threshold is set to 60 degrees celsius, and according to the temperature of the electronic device being less than or equal to 35 degrees celsius, the temperature of the electronic device being between 35 degrees celsius and 60 degrees celsius, and the temperature of the electronic device being greater than or equal to 60 degrees celsius, the temperature levels of the heating features are divided into three levels, and the temperature levels are divided into a first level, a second level and a third level, which correspond to the corresponding heating features respectively.
It should be noted that the parameter setting and the grade division in table 1 are only for explaining the technical solution of the present embodiment, and are not used to limit the technical solution of the present application, and the specific parameter setting and the grade division may be set and adjusted continuously in practice according to different actual conditions of different devices, so that the parameter setting and the grade division better conform to the actual operating conditions of the devices.

After the electronic equipment acquires the power consumption characteristics of the electronic equipment, the power consumption level corresponding to the power consumption characteristics is acquired according to the power consumption characteristics. For example, referring to table 1, if the power consumption characteristic of the electronic device is acquired by the electronic device that the battery is not charged and the electric quantity is greater than or equal to 50% of the battery capacity, the power consumption level is the first level.
After the electronic equipment acquires the heating characteristics of the electronic equipment, the temperature level corresponding to the heating characteristics is acquired according to the heating characteristics. For example, referring to table 1, if the electronic device obtains the heat generation characteristic of the electronic device that the current temperature of the electronic device is 33 degrees celsius, the temperature level is the first level.
And acquiring the power consumption heating state of the electronic equipment according to the power consumption level and the temperature level. For example, please refer to table 1, where the power consumption level of the electronic device obtained by the electronic device is a first level, and the temperature level of the electronic device obtained by the electronic device is a first level, as can be seen from table 1, the state of the power consumption heating feature of the electronic device is a first state, and then it is determined that the frame rate range of the preview frame rate can be increased, so as to improve the fluency of the video image, the photographing image, or the shooting image. Similarly, if the state of the power consumption heating feature of the electronic device is determined to be the second state, the frame rate range of the preview frame rate needs to be reduced, thereby reducing the power consumption of the electronic device.

Specifically, the electronic device acquires a power consumption heating state of the electronic device, acquires a target frame rate range corresponding to the power consumption heating state according to the power consumption heating state, and adjusts the frame rate range of the preview frame rate to the target frame rate range. With reference to table 1, if the power consumption heating state of the electronic device is the first state, the target frame rate range for acquiring the preview frame rate is 10 to 30fps, and the electronic device adjusts the preview frame rate range of the video component to 10 to 30fps, so as to achieve dynamic adjustment of the preview frame rate range, and balance between the power consumption of the electronic device and the smoothness of image display of the electronic device is obtained.

if the frame rate range of the preview frame rate is smaller than the target frame rate range, increasing the frame rate range of the preview frame rate to the target frame rate range;
and if the frame rate range of the preview frame rate is equal to the target frame rate range, not adjusting.
Specifically, the electronic device acquires a target frame rate range of a preview frame rate corresponding to a power consumption heating state of the electronic device, compares the frame rate range of the preview frame rate with the target frame rate range, and determines whether to increase the frame rate range of the preview frame rate, decrease the frame rate range of the preview frame rate, or not to adjust the frame rate according to a comparison result. If the frame rate range of the preview frame rate is larger than the target frame rate range, reducing the frame rate range of the preview frame rate to the target frame rate range, if the frame rate range of the preview frame rate is smaller than the target frame rate range, increasing the frame rate range of the preview frame rate to the target frame rate range, and if the frame rate range of the preview frame rate is equal to the target frame rate range, not adjusting. For example, if the frame rate range of the preview frame rate is 10 to 25fps, if the range of the obtained target frame rate is 10 to 30fps, the frame rate range of the preview frame rate is increased to 10 to 30fps, if the range of the obtained target frame rate is 5 to 20fps, the frame rate range of the preview frame rate is decreased to 5 to 20fps, and if the range of the obtained target frame rate is 10 to 25fps, no adjustment is performed.

step 906, the electronic equipment judges that the power consumption heating state is in a first state;
step 907, the electronic device determines that the power consumption heating state is in the second state.
It should be noted that, although the steps in the flowchart of fig. 9 are shown in sequence as indicated by arrows, the steps are not necessarily executed in sequence as indicated by the arrows. Since the three conditions of the power consumption of the electronic device, the power consumption of the electronic device and the temperature of the electronic device are in parallel, the steps may be performed in other sequences, for example, the electronic device may perform the detection of the three conditions simultaneously. Moreover, at least a portion of the steps in fig. 7 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performance of the sub-steps or stages is not necessarily sequential, but may be performed in turn or alternately with other steps or at least a portion of the sub-steps or stages of other steps.
In one embodiment, the step of adjusting a frame rate range of an image display preview frame rate of the electronic device according to a preset rule according to the power consumption heating state includes:

and if the power consumption heating state of the electronic equipment is judged to be in the second state, reducing the frame rate range of the preview frame rate to a second target frame rate range.
Specifically, after determining that the power consumption heating state of the electronic device is in the first state or the second state, the electronic device adjusts the frame rate range of the preview frame rate of the electronic device to a target range according to a preset rule, for example, if the electronic device determines that the power consumption heating state of the electronic device is in the first state, the frame rate range of the preview frame rate is increased to a first target frame rate range, the first target frame rate range includes 10 to 30fps, so as to increase the smoothness of the image displayed by the video component, and prevent a picture of a video call, a picture of a photography or a video camera from being stuck, please refer to fig. 10(a) and fig. 10(b), where fig. 10(a) is a schematic diagram of a picture being stuck in one embodiment, and fig. 10(b) is a schematic diagram of a picture in fig. 10(a) after dynamically increasing the frame rate range of the preview frame rate; if the electronic equipment judges that the power consumption heating state of the electronic equipment is in a second state, the frame rate range of the preview frame rate is reduced to a second target frame rate range, the second target frame rate range comprises 5-20 fps, so that the power consumption of the image displayed by the video component is reduced, the electronic equipment is enabled to keep a good working state, further the frame rate range of the preview frame rate of the electronic equipment is dynamically adjusted, balance is obtained between the fluency of the image displayed by the electronic equipment and the power consumption of the electronic equipment, the working state of the electronic equipment is optimized, and the efficiency of video conversation, shooting or shooting is improved.
