A target area is determined according to an input operation on a screen. A scheme for reducing power consumption of the target area is determined according to a layer allocation strategy of a currently running application, where the scheme is selected from a group consisted of reducing an image resolution in the target area and reducing power consumption of layers corresponding to the target area. Power consumption of the target area is reduced with the scheme determined.
Implementations of the disclosure will be detailed below with reference to the accompanying drawings.
At block 120, an operation area is determined according to a position of an input operation on a screen of the terminal.
For example, the terminal in this implementation may be a device having a display screen, such as a mobile phone, a smart watch, a tablet computer, a game machine, a personal digital assistant, and a digital multimedia player.
In an implementation, the input operation may include a touch input operation or an eye-focus input operation. In the case that the input operation is the touch input operation, the screen of the terminal is a touch screen for example, and the touch input operation of the user is received via the touch screen. In the case that the input operation is the eye-focus input operation, the terminal may include a camera (e.g., a front camera or a rotatable camera disposed at a front surface of the terminal) disposed at the top of the screen of the terminal. The camera is configured to capture a face image. A focus position of user's eyes on the screen is determined by recognizing positions of eyeballs. In this way, the eye-focus input operation of the user is received. The input manner may be applicable to a terminal having a large screen for example.
For example, the position of the input operation of the user on the screen can be understood as a position that the user is interested in. As an example,
In an implementation, the method may include the following. A center position (or referred to as an operation center) of the input operation on the screen is determined. An operation object is determined according to coordinates of the center position on the screen. The operation area is determined according to an area where the operation object locates. One of advantages of this implementation is that the operating area can be accurately determined. Similar to the above example, in
For example, if the input operation is a touch input operation, the method may further include the following. The operation area is determined to be a closed area, where the closed area is formed by an operation trajectory of the touch input operation on the screen.
In an implementation, if the input operation is a touch input operation, the method may further include the following. The operation area is determined to be an area other than the closed area, where the closed area is formed by the operation trajectory of the touch input operation on the screen. Compared with the foregoing manner, this manner can accurately determine the operation area by enhancing the interaction between the terminal and the user, and can also be applicable to a case where an area that the user is not interested in is smaller than an area that the user is interested in.
The above two manners can be set by default or selected by the user. Before the user starts to circle an area, the user may be prompted, such as “please circle your area of interest” or “please circle an area where a power reduction operation needs to be performed”.
At block 130, power consumption of a target area other than the operation area is reduced.
The power consumption of the target area may be reduced by reducing an image resolution in the target area or reducing power consumption of layers corresponding to the target area.
For example, the target area may include all or part of areas on the screen other than the operation area. For example, according to system settings or user settings, a preset area of the screen can be set to be an area that cannot be determined as the target area. In this case, the target area is all the areas on the screen other than the operation area and the preset area. The preset area may vary according to a specific display scenario, where display scenarios can be distinguished according to factors such as currently running applications (or process identifiers of the applications), sensing data acquired by a sensor, touch data, and properties of layers of applications.
In this implementation, an operating system loaded in the terminal may be an Android® system, a windows phone (WP) operating system, a Linux system, an iphone operating system (IOS), or the like. For ease of illustration, in the following, this implementation will be described in conjunction with the Android® system.
The Android® system is taken as an example to briefly describe a process from generation of a to-be-displayed image to display of the to-be-displayed image in the Android® system.
First, in an application layer, each application (hereinafter, “APP” for short) contains one or more layers, and each of multiple applications APP 1, APP 2 . . . APP N performs a layer-rendering operation (i.e., rendering an image on a layer) separately according to application design conditions of each of the multiple applications (generally, determined by a corresponding Android® package (APK)). After the rendering operation, each application sends one or more layers rendered by each application to a layer composite module (e.g., surface flinger) that performs a layer composite operation.
Then, in a framework layer, a layer list containing all layers (including visible and invisible layers) is generated, and the layer list is defined as ListAll. The layer composite module selects the visible layers from the ListAll to form a visible-layer list, and the visible-layer list is defined as DisplayList. Then, the layer composite module finds an unoccupied frame buffer (FB) from three reusable frame buffers in the Android® system. In the unoccupied FB, according to application configuration information, for example, which layer should be bottomed, which layer should be topped, which area is visible and which area is transparent, etc., by means of a composite operation, the layers contained in the DisplayList are superimposed to obtain a final to-be-displayed image.
In a kernel layer, the to-be-displayed image is transmitted to a display hardware, where the display hardware includes a controller and a display screen, so that the to-be-displayed image is finally displayed on the display screen. The type of the display screen is, for example, a liquid crystal display (LCD).
In addition, during a display refresh process, for the Android® system, a vertical synchronization (Vsync) refresh mechanism is introduced.
In a layer-rendering process, a layer composite process, and a layer refresh display process of the terminal, three kinds of frame rates are involved, which are a rendering frame rate, a composite frame rate, and a refresh rate, respectively.
The rendering frame rate is used for triggering the layer composite module to perform the composite operation after each application finishes the layer-rendering operation. The rendering frame rate can also be understood as frames of layers rendered per unit time (e.g., one second). The rendering frame rate includes a rendering frame rate of an application and a rendering frame rate of a layer. There may be more than one application currently running in the Android® system, and each application may include multiple layers. For example, a video player application generally includes three layers: one layer (defined as U1) for displaying video contents, and two SurfaceView-type layers, where one layer (defined as U2) is set to display contents of bullet-screen, and another layer (defined as U3) is set to display user-interface (UI) controls (e.g., a playback progress bar, a volume control bar, and various control buttons, etc.) and display advertisements. The rendering frame rate of the application refers to the number of times that each application performs the rendering operation per unit time, where one or more layers may be rendered when performing a rendering operation. The rendering frame rate of the layer refers to the number of times that a layer of the same number or name (e.g., U1, U2, or U3) is triggered to be rendered per unit time.
The composite frame rate is used for compositing layers rendered by respective applications to a to-be-displayed image. The composite frame rate can also be understood as frames of an image composited per unit time.
The refresh rate refers to a frame rate according to which an image displayed on the display screen of the terminal is refreshed. The display screen may be refreshed at a refresh rate of 60 Hz.
As an implementation, a processing manner of reducing the image resolution in the target area may be applicable to a case where an area is directly divided only according to a display image, regardless of whether the operation area and the target area are in a same layer. Reducing the image resolution in the target area may be implemented in a layer-rendering stage or a layer composite stage. In an implementation, a coordinate range of the target area in a display image is sent to a layer composite module. According to the coordinate range of the target area, respective sub-coordinate ranges of the target area in multiple layers are calculated via the layer composite module. Each of the sub-coordinate ranges is sent to a corresponding application via the layer composite module, whereby respective applications reduce the image resolution in the target area according to respective sub-coordinate ranges when rendering the multiple layers corresponding to the target area. In this way, a rendering process can be simplified during a layer-rendering stage, thereby saving rendering time and reducing power consumption. In another implementation, the coordinate range of the target area in the display image is sent to the layer composite module, and the image resolution in the target area can be reduced in the layer composite process according to the coordinate range of the target area. In this way, the composite process can be simplified during a layer composite stage, and so composite time can be saved and power consumption can be reduced. The image resolution can be reduced by means of related schemes of image processing.
The main difference between reducing the power consumption of the layers corresponding to the target area and reducing the image resolution in the target area described above is the following. A resolution of a part of an image in a same layer can be reduced when reducing the image resolution in the target area. However, when reducing the power consumption of one layer corresponding to the target area, the power consumption of the entire layer is reduced.
In an implementation, reducing the power consumption of the layers corresponding to the target area may include the following processing manners. In a first processing manner, a rendering frame rate of each of the layers corresponding to the target area is reduced. In a second processing manner, a resolution of each of the layers corresponding to the target area is reduced. In a third processing manner, the layers corresponding to the target area are removed from a set of layers to-be-composited (e.g., the DisplayList). In a fourth processing manner, play volume of each of the layers corresponding to the target area is decreased.
For the first processing manner, as an implementation, the rendering frame rate of each of the layers can be reduced by lowering the frequency of a reference signal (e.g., a Vsync signal) for layer rendering. At this time, the frequency of a Vsync signal for rendering the layers corresponding to the target area is reduced during a layer-rendering process, and the frequency of a Vsync signal during a layer composite process and the frequency of a Vsync signal during a refresh display process remain unchanged. For example, the frequency of the Vsync signal during the layer-rendering process, the frequency of the Vsync signal during the layer composite process, and the frequency of the Vsync signal during the refresh display process are all 60 Hz, and when the frequency of the Vsync signal for rendering the layers corresponding to the target area is reduced from 60 Hz to 50 Hz, the frequency of the Vsync signal during the layer composite process and the frequency of the Vsync signal during the refresh display process are still 60 Hz. In addition, the rendering frame rate of each of the layers can also be reduced by changing a response mechanism of a layer-rendering operation in response to reference signals. As an example, make a response to a (2n+1)th signal received, and for a (2n)th signal received, no response is made. As another example, take n signals (e.g., five signals) as a group, make a response to signals having a first type of preset number (e.g., 1, 2, 4, 5) in each group, and for signals having a second type of preset number (e.g., 3) in each group, no response is made.
For the second processing manner, reducing the resolution of each of the layers corresponding to the target area refers to reducing an image resolution of each of the layers corresponding to the target area, which can be implemented in the layer-rendering stage.
For the third processing manner, the operation of removing the layers corresponding to the target area from the set of layers to-be-composited may be implemented via a layer composite module. For instance, a coordinate range of the target area in a display image is sent to the layer composite module. The layer composite module identifies identifiers (such as a name or a number) of the layers corresponding to the target area according to the coordinate range of the target area, and removes corresponding layers from the set of layers to-be-composited according to the identifiers. As such, contents of the layers corresponding to the target area are not contained in a composite image to-be-displayed.
For the fourth processing manner, as an implementation, the layers corresponding to the target area may be layers corresponding to a video advertisement or layers with a sound effect. In this situation, play volume of each of the layers corresponding to the target area can be decreased, and so power consumption of the terminal can be reduced.
The above four types of power reduction processing manners may be combined with each other. For example, the first processing manner and the fourth processing manner are adopted simultaneously, the first processing manner and the second processing manner are adopted simultaneously, the first processing manner, the second processing manner, and the fourth processing manner are adopted simultaneously, or the like.
According to the method for controlling a terminal provided in this implementation, the input operation of the user on the screen of the terminal can be received, the operation area can be determined according to the position of the input operation on the screen, and the power consumption of the target area other than the operation area can be reduced, where reducing the power consumption of the target area includes reducing the image resolution in the target area or reducing the power consumption of the layers corresponding to the target area. By adopting the above technical solution, the power consumption of the target area can be selectively reduced according to the input operation of the user, thereby reducing system power consumption of the terminal.
At block 701, a touch input operation of a user on a screen of a terminal is received.
At block 702, an operation area is determined to be an area other than a closed area, where the closed area is formed by an operation trajectory of the touch input operation on the screen.
At block 703, power consumption of a target area other than the operation area is reduced.
The power consumption of the target area may be reduced by reducing an image resolution in the target area or reducing power consumption of layers corresponding to the target area.
In an implementation, an area other than the operation area may be a closed area formed by an operation trajectory of the touch input operation on the screen.
The manner of reducing the power consumption of the target area may be selected according to a layer allocation strategy of each application. Similarly, taken the game application A as an example, if display contents of the game application A on the game area 801 and display contents of the game application A on the background area 802 are all rendered on a same layer, the image resolution in the target area can be reduced. If the display contents of the game application A on the game area 801 and the display contents of the game application A on the background area 802 are respectively rendered on different layers, the power consumption of the layers corresponding to the target area can be reduced, that is, power consumption of layers corresponding to the closed area 803 is reduced. For the specific processing, reference may be made to the related descriptions above, and it will not be described in further detail herein.
In this implementation, the area that the user is not interested in can be determined according to a circle selection operation on the screen, and power consumption of images or layers corresponding to the area that is not of interest can be reduced, thereby reducing power consumption of the terminal and prolonging battery life.

According to the device for controlling a terminal of this implementation, the power consumption of the target area can be selectively reduced according to the input operation of the user, and so system power consumption of the terminal can be reduced.
In an implementation, the power consumption of the layers corresponding to the target area is reduced as follows. A rendering frame rate of each of the layers corresponding to the target area is reduced. A resolution of each of the layers corresponding to the target area is reduced. The layers corresponding to the target area are removed from a set of layers to-be-composited. Play volume of each of the layers corresponding to the target area is decreased.
In an implementation, the input operation includes a touch input operation or an eye-focus input operation.
In an implementation, the operation-area determining module includes an operation-center determining unit, an operation-object determining unit, and an operation-area determining unit. The operation-center determining unit is configured to determine a center position of the input operation on the screen.

The operation-area determining unit is configured to determine the operation area according to an area where the operation object locates.

In an implementation, the image resolution in the target area are reduced as follows. A coordinate range of the target area in a display image is sent to a layer composite module. According to the coordinate range of the target area, respective sub-coordinate ranges of the target area in multiple layers are calculated via the layer composite module. Each of the sub-coordinate ranges is sent to a corresponding application via the layer composite module, whereby respective applications reduce the image resolution in target area according to respective sub-coordinate ranges when rendering the multiple layer corresponding to the target area. In another implementation, the image resolution in the target area are reduced as follows. The coordinate range of the target area in the display image is sent to the layer composite module. According to the coordinate range of the target area, the image resolution in the target area are reduced via the layer composite module in a layer composite process.
