Typically, the power consumption is expressed as the current consumption at rated voltage, and the unit can be milliamp mA or microampere uA; and in particular to the current drawn on the terminal battery. The mobile terminal (for example, a smart phone) mainly has components such as WLAN, bluetooth, GPS (Global Positioning System, global satellite positioning system), display screen, CPU (Central Processing Unit ), sensor, camera, flash lamp, etc. as power consumption sources. The excessive power consumption can cause the problems of excessive power consumption, body heating and the like of the mobile phone.

Wherein the camera application is one of the components with higher power consumption. The use experience of a user when using a camera application is controlled by a variety of camera operating parameters, several of which have a significant impact on the use experience as well as power consumption are described below.

The camera frame rate is a camera operating parameter that means the number of image frames acquired per second by the camera. The highest camera frame rate supported by a typical terminal is 30 frames/second. The rendering frame rate is a parameter closely associated with the camera and represents the number of image frames drawn per second of the screen, i.e. for displaying the image captured by the camera. For special effect camera applications, complex processes such as face recognition, a graph repair algorithm, a sticker, a filter and the like are usually required to be performed on an original image frame acquired by a camera, and the partial processes are usually time-consuming and occupy a large amount of resources of a CPU (Central Processing Unit ) and a GPU (Graphic Processing Unit, graphics processor), so that it is more necessary to reduce power consumption related to the camera by a certain technical means for special effect camera applications.

Camera resolution is another camera operating parameter, meaning that the higher the resolution, the more complete the image detail remains, and the better the preview experience, but the corresponding increase in the number of pixels processed per frame results in more system resources being consumed.

Thus, when the camera application is running, the main power consumption is derived from the consumption of the CPU and GPU in the system camera and in the image processing process. In view of this, the embodiments of the present disclosure provide a power consumption control method, which aims to reduce power consumption caused by a camera application, and at the same time ensure a use experience when a user uses a camera (e.g., ensure smoothness when the camera application runs, sharpness of a shot picture, etc.).

Fig. 1 is a flowchart of a power consumption control method in an embodiment of the present disclosure. The method may be performed by a power consumption control device, which may be implemented in software and/or hardware, where the device may be configured in an electronic device, such as a mobile terminal, including, but not limited to, a smart phone, a palm top computer, a tablet computer, a wearable device with a display screen, a desktop computer, a notebook computer, an all-in-one machine, a smart home device, and the like.

As shown in fig. 1, the method specifically may include:

And 110, when the camera application is detected to be started, determining a camera operation parameter set adapted to the target terminal according to the performance level of the target terminal, wherein the camera operation parameter set comprises at least one operation parameter.

The target terminal in the embodiment of the disclosure has a shooting function. After the camera application is started, a preview interface appears on a display screen of the target terminal, and objects in the shooting range of the camera can be determined through the preview interface.

Optionally, the performance level of the target terminal may be determined by a model of the target terminal. The processing performance of the target terminal can be determined according to the model of the target terminal, the target terminal can be divided into different performance levels according to the processing performance, for example, the target terminal with higher processing performance corresponds to a first-level performance level, the target terminal with middle processing performance corresponds to a second-level performance level, and the target terminal with lower processing performance corresponds to a third-level performance level. It will be appreciated that the processing power of the CPU of the target terminal corresponding to the primary performance level is typically relatively high.

The performance level of the target terminal may be obtained by a setting logic each time the camera application start is detected; or the camera application start-up is detected for the first time, the performance level of the target terminal is stored after being acquired through the setting logic acquisition, and when the camera application start-up is detected again, the stored performance level is directly read and is not acquired through the setting logic. It will be appreciated that reading already stored data consumes less system resources than retrieving data by the set logic. Therefore, when the camera application is detected to start for the first time, the camera application is acquired in real time through the setting logic, after the performance level of the target terminal is acquired, the performance level is stored, when the camera application is detected to start again, the stored performance level is directly read, and the purpose of reducing the system resource consumption can be achieved without acquiring the stored performance level in real time through the setting logic. On the other hand, the performance level of the target terminal is a relatively stable data, which does not substantially change over a long period of time, even over the entire life cycle of the target terminal. Therefore, the performance level of the target terminal is obtained only once through the setting logic, and the method has strong executable performance.

In the special effect camera application (the special effect camera application refers to an application that performs some special effect processing on an image when the image is shot, for example, identifies a face, adjusts brightness, or adds a filter to perform further processing on the image), taking a camera frame rate as an example, since a large system resource is consumed in rendering the image or performing special effect processing on the image, even if a high camera frame rate, for example, 30fps is set in a target terminal with low processing performance, the rendering frame rate cannot reach 30fps, so that the waste of the camera frame rate is caused, and meanwhile, a high camera frame rate causes high power consumption. Based on the above, in the technical solution of the embodiment of the present disclosure, the camera operation parameters are set pertinently according to the performance level of the target terminal, so as to achieve the purpose of reducing power consumption without reducing the use experience of the user.

Wherein the camera operating parameter set includes at least one operating parameter. The operating parameters include, but are not limited to, camera frame rate, camera resolution, anti-shake parameters, auto-focus parameters, and the like. Each operating parameter corresponds to a preset value range or a set of selectable data, which is related to the performance level of the target terminal. For example, the predetermined range of values corresponding to the camera frame rate may be [15,20], and the set of selectable data corresponding to the camera resolution may be {1536×2048,1920×2560}, for example. The upper limit of the value of each operation parameter is the upper limit of the value which can be supported or competed by the target terminal, and can be understood as the upper limit of the processing performance of the target terminal; the lower limit of the value of each operation parameter indicates that the processing performance of the target terminal can be better played, and the value of the target terminal cannot be damaged for the use experience of a user. Taking the camera frame rate as an example, on a target terminal with low processing performance, since an algorithm, rendering task, and the like associated with the camera consume a large amount of system resources, even if the camera frame rate is set to 30fps, the rendering frame rate can only reach 20fps at the highest, and therefore the upper limit of the processing performance of the target terminal is 20fps. When the frame rate of the camera is set to be the upper limit of 20fps, the smoothness of images seen by a user is higher, but the target terminal generates heat and has serious power consumption; if the camera frame rate is set to the lower limit of 15fps, the smoothness is impaired (at the visual level, the user does not normally feel the impairment and thus has no influence on the user's experience), but the target terminal heat generation and power consumption can be greatly reduced.

For example, reference is made to a camera operation parameter set adapted to target terminals with different performance levels as shown in table 1 below, where a preset value range corresponding to an operation parameter may be stored together with the camera operation parameter set, as shown in table 1, or may be stored separately and independently from the camera operation parameter set.

Based on the following table 1, the determining a set of camera operation parameters adapted to the target terminal according to the performance level includes:

and determining a camera operation parameter set adapted to the target terminal based on a mapping relation between a preset performance level and the camera operation parameter set.

Table 1: camera operation parameter set adapted to target terminals of different performance levels

Step 120, controlling the camera application to run on the target terminal based on the camera running parameter set; wherein the camera applications have different power consumption when running on target terminals of different performance levels.

Specifically, the target value of the operation parameter may be determined according to a preset value range corresponding to the operation parameter in the camera operation parameter set. A specific value in the preset value range may be selected as the target value, for example, a maximum value in the preset value range is selected, a minimum value in the preset value range is selected, or an intermediate value in the preset value range is selected, etc.

Optionally, a specific value within the preset value range may be dynamically selected as the target value, for example, a notification is displayed to the user first in a pop-up window manner, the user determines which value to select based on the notification, and then a specific value is selected according to the user's selection.

Further, the specific value may be dynamically determined from a preset value range based on the current resource consumption condition of the target terminal as the target value of the operation parameter.

Illustratively, the controlling the camera application to run at the target terminal based on the camera running parameter set includes: determining a target value of the operation parameters in the camera operation parameter set according to the current resource consumption information of the target terminal; and controlling the camera application to run on the target terminal based on the target value.

The current resource consumption information of the target terminal includes, but is not limited to: the remaining capacity of the battery, the memory occupancy rate, the CPU occupancy rate and the like.

Further, the determining, according to the current resource consumption information of the target terminal, the target value of the operation parameter in the camera operation parameter set includes: acquiring the current residual electric quantity of the target terminal; and determining a target value of the operation parameter according to the residual electric quantity and a preset value range of the operation parameter, wherein the preset value range is related to the performance level of the target terminal, and the lower the residual electric quantity is, the lower the power consumption of the camera application when the target terminal operates based on the target value is.

When the residual electric quantity is relatively large, the operation parameter value which can obtain high fluency is selected as much as possible, and when the residual electric quantity is relatively low, the power consumption is reduced as much as possible, and the operation parameter value with relatively small power consumption is selected.

In one embodiment, the determining the target value of the operation parameter according to the remaining power and the preset value range of the operation parameter includes: when the residual electric quantity is lower than a preset degradation threshold value, determining a target value of the operation parameter as a minimum value in the preset value range; and when the residual electric quantity is higher than the preset degradation threshold value, determining the target value of the operation parameter as the maximum value in the preset value range.

Alternatively, the target value of the corresponding operation parameter may be determined according to a difference value that the remaining power is lower than a preset degradation threshold. For example, the performance level of the target terminal is one level, the current remaining power is 60%, the preset degradation threshold is 45%, the operation parameter corresponding to the preset degradation threshold 45% is the camera frame rate, the preset value range of the camera frame rate is [25,30], the difference value of the remaining power 60% higher than 45% is 15%, and at this time, the camera frame rate can be set to any value greater than 25 and less than 30, for example, 28; if the remaining power is 90%, the camera frame rate may be set to 29 or the like. In other words, when the remaining electric power is higher than the preset threshold value, the maximum value in the preset value range is not necessarily selected as the target value.

It should be noted that the preset degradation thresholds corresponding to different kinds of operation parameters are different, and the preset degradation threshold is determined based on the influence coefficient of the corresponding operation parameter on power consumption.

For example, reference is made to the types of operating parameters corresponding to different preset degradation thresholds as shown in table 2.

Table 2: the operation parameter types corresponding to different preset degradation thresholds

Kind of operating parameters	Presetting a degradation threshold
		Camera frame rate	＜45％
Camera resolution	＜30％
		Anti-shake	＜20％
Automatic focusing	＜20％
		……	……

The meaning of the above table 2 is: when the remaining power is lower than 45% but higher than 30%, the camera frame rate is adjusted, and the camera frame rate can be adjusted to be the minimum value in the value range, or one of the values larger than the minimum value in the value range and smaller than the maximum value in the value range is determined as the target value of the camera frame rate according to the difference between the current remaining power and 45%. When the remaining power is lower than 30% but higher than 20%, the resolution of the camera is adjusted in a similar manner to the frame rate of the camera, and the description is omitted. And when the residual electric quantity is lower than 20%, adjusting the anti-shake parameter and the automatic focusing parameter.

According to the power consumption control method provided by the embodiment of the disclosure, in the use process of the camera application, the camera operation parameters are configured for the target terminal in a personalized manner according to the performance level of the target terminal, so that the purpose of reducing the power consumption of the camera in operation can be achieved, the power consumption of the target terminal is reduced, and the use experience of a user is ensured.

In summary, on the basis of the foregoing embodiment, referring to a flow chart of a power consumption control method as shown in fig. 2, the method specifically includes the following steps:

when the camera application is detected to be started for the first time, the performance level of the target terminal is acquired, and the performance level is stored, so that the camera application can be conveniently and directly read when the subsequent camera application is started again.

Determining a camera operation parameter set of the adaptive target terminal according to the performance level of the target terminal when the camera application is detected to be started each time; then obtaining the current residual electric quantity of the target terminal; determining a specific value, namely a target value, of each operation parameter according to the residual electric quantity; the control camera application is run based on the target value.

Further, the obtaining the current remaining power of the target terminal includes:

and periodically acquiring the current residual electric quantity of the target terminal according to a preset frequency. For example, collecting the current residual electric quantity every 60s, if the residual electric quantity is lower than a preset degradation threshold (for example, 45%), checking whether various types of parameters in a camera operation parameter set fall into a degradation interval one by one, and if so, dynamically reducing the value of the parameters; otherwise, if the residual electric quantity is higher than the preset degradation threshold value, the value of the corresponding parameter is adjusted upwards.

For example, referring to a flowchart for dynamically adjusting camera operation parameters as shown in fig. 3, when a camera application is detected to be started, the remaining power of the target terminal is detected every 60s, if the remaining power is lower than a preset degradation threshold, the parameters falling in the degradation interval are adjusted down, otherwise, the parameters not falling in the degradation interval are adjusted up. Wherein the camera frame callback represents the process of obtaining the image frame by the camera application adjusted parameters.

For example, if the detected residual electric quantity for the first time is 40% and is lower than the preset degradation threshold value by 45%, the parameter-camera frame rate corresponding to the preset degradation threshold value by 45% is adjusted to be a lower limit value in the value range; assuming that the target terminal is in a charging state during the period, when the detected residual power becomes 50% in the third time and is higher than the preset degradation threshold value by 45%, the camera frame rate which is adjusted down before is adjusted up, and the camera frame rate is restored to the upper limit value in the value range. By dynamically adjusting the camera operation parameters matched with the target terminal, the purpose of reducing power consumption can be achieved, the processing performance of the target terminal can be reasonably utilized, the phenomenon that the target terminal seriously heats is relieved, and the purpose of prolonging the service life of the target terminal is achieved; and the use experience of the user can be ensured.
