Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
In the related art, by sliding the screen up and down in the video playing area to adjust the brightness, when a specific scene, such as a small window interface and a full screen interface, plays a video at the same time, after the brightness of the small window interface is adjusted, the screen brightness of the full screen interface cannot be adjusted, so that the screen brightness requirement of a user on the full screen interface cannot be met. For example, the video software a adopts a full screen interface to play video, the video software B adopts a picture-in-picture interface or a small window interface to play video, wherein the picture-in-picture interface or the small window interface is on the top layer, and if the screen brightness is adjusted by sliding the screen in the video playing interface of the video software B on the top layer, then the screen brightness cannot be successfully adjusted when the screen brightness is adjusted by sliding the screen in the video playing interface of the video software a on the bottom layer. Therefore, in the multi-window mode, the brightness of a certain area of the screen cannot be finely controlled, the user cannot adjust the screen brightness of the bottom window according to own wish, and the user experience is poor.
In an exemplary embodiment of the disclosure, a method for adjusting screen brightness is provided, and the method is applied to a terminal, where the terminal includes an electronic device supporting a picture-in-picture or a small window function, such as a smart phone and a tablet. Fig. 1 is a flowchart illustrating a method of adjusting screen brightness according to an exemplary embodiment, as shown in fig. 1, the method including the steps of:
step S101, in a multi-window mode, receiving a brightness adjustment instruction;
step S102, determining a target window corresponding to a brightness adjustment instruction;
step S103, adjusting the brightness parameter of the target window to adjust the brightness in the target window to the target brightness.
In an exemplary embodiment of the present disclosure, in order to overcome the problem that the screen brightness of any window cannot be adjusted in the multi-window mode in the related art, a method for adjusting screen brightness is provided. When a brightness adjustment instruction is received in the multi-window mode, a target window corresponding to the brightness adjustment instruction is determined, brightness parameters of the target window are adjusted according to the brightness adjustment instruction, and brightness in the target window is adjusted to target brightness. The method can realize the adjustment of the brightness of the target window in the screen, so that the screen brightness of any window area can be adjusted in a multi-window mode.
In step S101, determining whether the terminal is in the multi-window mode according to the parameters related to the multi-window mode, and when the terminal is in the multi-window mode, receiving a brightness adjustment instruction, where the brightness adjustment instruction may be an instruction supported by any terminal to adjust the brightness of the screen, and may be a default adjustment instruction of an operating system of the terminal, for example, an adjustment instruction for adaptively adjusting the brightness of the screen according to the brightness of surrounding environment by the operating system of the terminal; the adjustment instruction of the user-defined operation may also be an adjustment instruction of the user, for example, the user may adjust the brightness by sliding a brightness adjustment button on a window or the user may adjust the brightness of the screen by a preset touch screen operation.
In step S102, when determining a target window corresponding to the brightness adjustment instruction, if the brightness adjustment instruction is adaptive adjustment of the terminal to the current window, determining the target window according to click of the window by the user, for example, the window clicked by the user is the target window; if the brightness adjustment instruction is through a brightness adjustment button in the window or through a screen of a sliding window area, the corresponding window is the target window. The target window at this time is the focus window.
For example, in the two-window mode, one window is a playing interface of the C video software, the other window is a playing interface of the D video software, and if the window playing the C video is the currently playing window, i.e. the focus window, the target window and the focus window are the same window, and the target window is the window playing the C video. If the user clicks the window of the D video software again at this time or slides the screen in the window area of the D video software to adjust the screen brightness of the D video software area, the target window becomes the window of the D video software.
In step S103, the target brightness to be adjusted can be obtained by the brightness adjustment command, and the brightness parameter of the target window is adjusted according to the target brightness, so that the brightness in the target window to be adjusted to the target brightness. In exemplary embodiments of the present disclosure, the corresponding screen area may be adjusted according to the needs of the user. Thus, the display of the terminal may be a display capable of local brightness adjustment, such as an LED display.
In the exemplary embodiment of the disclosure, in the multi-window mode, the brightness parameter of the target window is adjusted according to the brightness adjustment instruction by determining the target window corresponding to the brightness adjustment instruction, so that the brightness in the target window is adjusted to the target brightness, the area adjustment of the screen brightness in the multi-window mode is realized, and the technical effect of adjusting the screen brightness of any window area is achieved.
In an exemplary embodiment, the method for adjusting screen brightness further includes: and taking the target window area as an area to be regulated.
When the terminal determines to enter the multi-window mode, if the terminal is in the split screen mode at the moment, namely all window areas are spliced to fill the whole display screen area, after the target window is determined at the moment, the area of the target window is the area to be regulated.
In an exemplary embodiment, the method for adjusting screen brightness further includes: and taking all areas except the small window areas in the display screen as areas to be adjusted.
When the target window is a display screen of the terminal, other small window areas can cover a part of the target window, so that when the target window is adjusted, the technical effects of respectively adjusting the brightness of the small window screen and the brightness of the target window screen can be realized only by adjusting the areas outside the small window areas, and at the moment, all the areas outside the small window areas in the display screen are the areas to be adjusted in the target window.
In an exemplary embodiment, the entire display screen area is taken as the area to be adjusted.
When the target window is a display screen of the terminal, other small window areas can cover a part of the target window, and when brightness adjustment is performed on the whole display screen area, the part covered and shielded by the small window area cannot influence brightness of the small window, so that when the target window is adjusted, the whole display screen area is used as an area to be adjusted.
In an exemplary embodiment, fig. 2 is a flowchart of a method for adjusting screen brightness according to an exemplary embodiment, and as shown in fig. 2, the method for adjusting screen brightness further includes the following steps:
step S201, determining whether the target window is a window corresponding to a display screen of the terminal;
step S202, if the window is the window corresponding to the display screen of the terminal, determining the area to be adjusted in the target window.
After the target window is determined, whether the target window is a window corresponding to the display screen is determined, for example, whether the size of the target window is the size of the display screen is determined through the size of the target window, when the size of the target window is the same as the size of the display screen, the target window is indicated to be the window corresponding to the display screen, and if the size of the target window is smaller than the size of the display screen, the target window is indicated to be not the window corresponding to the display screen. If the target window is a window corresponding to the terminal display screen, the region to be regulated in the target window, namely the region except all small window windows, needs to be regulated. It will be appreciated that the size of the region to be adjusted at this point refers to the portion of the display that is visible to the user, e.g., the a-window is a floating window and the B-window is a window below the floating window, i.e., the a-window is floating over the B-window, where the size of the B-window is the area that does not include the a-window.
By determining the area to be adjusted, the sub-area fine adjustment of the screen brightness can be realized.
In an exemplary embodiment, the method for adjusting screen brightness further includes: and determining parameter information of the area to be adjusted in the target window, so as to determine the area to be adjusted in the target window according to the parameter information.
The parameter information of the area to be adjusted includes, for example, the size of the area to be adjusted and the position in the screen. The size area and location of the widget in multi-window mode can be calculated, for example, by the surfaefolinger module of the terminal operating system framework layer. When the target window is a window corresponding to the display screen of the terminal, namely, the area to be regulated is a full-screen area minus window areas of all the small windows, the parameter information of the area to be regulated can be calculated through the parameter information of the full-screen area and the parameter information of the small window area. The size of the area to be adjusted can be obtained by subtracting the size of the window area of all the small windows from the size of the full screen area, and the position of the area to be adjusted is determined according to the positions of all the small windows in the display screen.
In one example, the parameter information includes a starting position, a length, and a width of the area to be adjusted.
After the parameter information of the area to be regulated is determined, an area brightness setting interface can be preset in a kernel layer of the terminal operating system. And determining the initial position of the area to be regulated relative to the screen, and the length and width of the area according to the parameter information of the area to be regulated, and assigning the initial position and the length and width of the area to the corresponding parameters in the area brightness setting interface. For example, the area brightness setting interface may be a setb lightnessvue interface, which is expressed as:
setBrightnessValue(boolean isExcludeErea,int startX,int StartY,int width,int height，int brightness)
in the area brightness setting interface, when one vertex of a display screen of a terminal is used as an origin, the transverse direction is used as an X-axis direction, the longitudinal direction is used as a Y-axis direction, a startX parameter is used for representing an area starting X-axis direction coordinate, a startY parameter is used for representing an area starting Y-axis direction coordinate, a width parameter is used for representing an area width, a height parameter is used for representing an area height, units of startX, startY, width, height are pixels, a brightness parameter is used for representing a brightness value to be regulated of the area, namely a target brightness value, an isexclusiereea parameter is used for determining whether the area is an area to be regulated, when the isexclusiereea parameter is 0, the area is represented as an area to be regulated, and when the isexclusiereea parameter is 1, the area is represented as not an area to be regulated.
After the parameter information of the area to be regulated is determined, the parameter information is sent to an area brightness setting interface, and the parameter information of the area to be regulated is assigned to the corresponding parameter in the area brightness setting interface so as to realize brightness regulation of the area to be regulated.
In an exemplary embodiment, the region brightness adjustment function is activated when the terminal is in the multi-window mode.
When the terminal is detected to enter the multi-window mode, the user is considered to need to carry out area brightness adjustment on the terminal, and the area brightness adjustment function is activated by calling the switching interface at the moment, so that the area adjustment on the screen can be realized at any time when the subsequent requirement on the area brightness adjustment on the screen exists. The switching interface is, for example, a transaction interface within the operating system framework. For example, when the terminal enters a split screen display mode, an area brightness adjustment function is activated to enable a user to adjust the brightness of any split screen.
In an exemplary embodiment, fig. 3 is a flowchart of a method for adjusting screen brightness according to an exemplary embodiment, and as shown in fig. 3, the method for adjusting screen brightness further includes the following steps:
step S301, when the terminal is in a multi-window mode, determining whether a window currently operated is a small window;
in step S302, if the currently operated window is a small window, the area brightness adjustment function is activated.
The currently operated window is a focus window, and the focus window is determined by traversing all windows in the multi-window mode and system parameters of the terminal, and whether the focus window is a window of a small window is determined. For example, the management window service (WMS, windowManagerService) of the framework layer of the terminal operating system traverses all windows in the current multi-window mode, and whether the window is a focus window is judged by the system attribute isFocused of the terminal. When the isFocused attribute value of the window is true, the window is indicated to be the currently operated window, namely, the focus window, and when the isFocused attribute value of the window is false, the window is indicated to not be the focus window. When the currently operated window is determined, it is determined whether the currently operated window is a widget, for example, whether the currently operated window is a widget or not through a terminal system attribute parameter, or whether the currently operated window is a widget or not through a size of the currently operated window. If the currently operated window is a small window, the subsequent window corresponding to the terminal display screen cannot be adjusted when the brightness adjustment is required, so that the operation of the screen for adjusting the regional brightness is described, and the regional brightness adjusting function is activated by calling the switching interface at the moment, so that the regional brightness adjustment of the screen can be realized at any time when the subsequent requirement for the regional brightness adjustment of the screen exists. The switching interface is, for example, a transaction interface within the operating system framework.

In exemplary embodiments of the present disclosure, the brightness of the window may be adjusted using a PWM (Pulse Width Modulation ) approach.
In an exemplary embodiment, setting the brightness parameter of the target window to a state to be adjusted includes: the value of the preset parameter is set as the brightness value of the target window to adjust the brightness of the target window by adjusting the value of the preset parameter.
The preset parameter is a parameter for adjusting the brightness of the screen in the terminal operating system, for example, the preset parameter is an override parameter, the brightness value of the target window is determined by a screen brightness parameter in the window, and the operating system of the terminal generally controls the brightness of the window by the following program statement:
WindowManager.LayoutParams lp＝getWindows().getAttributes()；
Lp.screenBrightness＝1.0f；
getWindows().setAttributes()；
the value corresponding to the screen brightness parameter is the brightness value of the target window.
And setting the value of the preset parameter as the brightness value of the target window, namely setting the value of the override parameter as the value of the screen brightness parameter of the target window, so that when a brightness adjustment instruction is received, the value of the brightness parameter screen brightness of the target window is adjusted by adjusting the value of the preset parameter override parameter.
