In addition, the touch screen 121 may be implemented in various types, such as resistive, capacitive, infrared, and surface acoustic wave. Other input devices 122 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, power switch keys, etc.), a trackball, a mouse, and a joystick.
The processor 13 is a control center of the mobile phone 01, and may be a single processor or a collective term for a plurality of processing elements. For example, the processor 13 is a Central Processing Unit (CPU), or may be an Application Specific Integrated Circuit (ASIC), or may be one or more Integrated circuits configured to implement embodiments of the present invention, such as: one or more microprocessors (DSPs), or one or more Field Programmable Gate Arrays (FPGAs).

The display unit 15 may include a display panel 151. Alternatively, the Display panel 151 may be configured in the form of a Liquid Crystal Display (LCD), an Organic Light-Emitting Diode (OLED), or the like.
Further, the touch screen 121 may cover the display panel 151, and when the touch screen 121 detects a touch operation thereon or nearby, the touch screen is transmitted to the processor 13 to determine the type of the touch event, and then the processor 13 provides a corresponding visual output on the display panel 151 according to the type of the touch event. Although the touch screen 121 and the display panel 151 are shown in fig. 1 as two separate components to implement the input and output functions of the mobile phone, in some embodiments, the touch screen 121 and the display panel 151 may be integrated to implement the input and output functions of the mobile phone.
In some other embodiments, the touch screen 121 may further include a pressure sensing sensor, so that when a user performs a touch operation on the touch screen 121, the touch screen 121 can also detect a pressure of the touch operation, and the mobile phone 01 can detect the touch operation more accurately.
Further, the mobile phone 01 may further include at least one sensor, such as a light sensor, a motion sensor, and other sensors.

Although not shown, the mobile phone 01 may further include a Wireless Fidelity (WiFi) module, a bluetooth module, a Global Positioning System (GPS) module, and the like, which will not be described herein.
The methods in the following embodiments can be implemented in the mobile phone 01 having the above hardware structure. Based on each module or component of the mobile phone 01 shown in fig. 1, an embodiment of the present invention provides a method for adjusting screen brightness, which introduces different screen brightness adjustment processes for different application scenes in detail. Specifically, as shown in fig. 2, the method for adjusting the screen brightness may include S201 to S203:
s201, the terminal device determines an application scene according to the type of the first application.
The first application is the application to which the current display interface belongs.
When a user touches the touch screen of the terminal device, the touch screen of the terminal device can detect the touch operation of the user on the touch screen, and sends related parameters generated according to the touch operation to the processor of the terminal device. And after receiving the parameters, the processor determines the object in the area corresponding to the touch operation as the touch object according to the parameters.
Illustratively, when a user presses an icon of a first application in the display interface of the mobile phone 01, the touch screen 121 of the mobile phone 01 may detect the pressing operation and send parameters generated according to the pressing operation to the processor 13 of the mobile phone 01. After receiving the parameter, the processor 13 may determine, according to the parameter, that the object of the pressing operation performed by the user is the icon of the first application; the processor 13 then controls the display panel 151 to display the first application so that the user can see the first application on the current display interface; the processor 13 determines the type of the first application and determines the application scenario according to the type of the first application.
For example, after the user presses the "WeChat" icon in the display interface of the mobile phone 01, the processor 13 of the mobile phone 01 determines that the object of the pressing operation by the user is the "WeChat" and determines that the type of the "WeChat" is the instant message application, and then the processor 13 determines that the application scene is the instant message scene according to the type of the "WeChat".
Illustratively, the application scenario in the embodiment of the present invention may include at least one of the following: a browser scene, a game scene, a video scene, an instant messaging scene, a photographic scene, and an e-book scene. The application scenarios in the embodiments of the present invention include, but are not limited to, the above application scenarios, which are not listed here.
For example, when the first application is ". times.browser", the corresponding application scene is a browser scene; when the first application is the video, the corresponding application scene is a video scene; when the first application is "QQ" or "WeChat" or the like, the corresponding application scenario is an instant message scenario.
S202, the terminal device determines an adjustment curve corresponding to the application scene according to the application scene and a corresponding relation between a preset application scene and the adjustment curve.
The application scenes correspond to the adjustment curves one by one, namely one application scene corresponds to one adjustment curve.
For example, the processor of the terminal device may preset a corresponding relationship between each application scenario and the adjustment curve, and store the corresponding relationship in the memory. After a user starts a first application, a processor of the terminal device determines an application scene, searches a corresponding relation between the application scene and an adjustment curve in a memory according to the application scene, and then searches the adjustment curve corresponding to the application scene from the adjustment curve according to the application scene and the corresponding relation between the application scene and the adjustment curve.
Since human eyes are more sensitive to brightness change under the condition of low screen brightness, when the screen brightness is low, the time for gradual change of the screen brightness is longer, and the step length of jump is smaller, and when the screen brightness is high, the time for gradual change of the screen is shorter, and the step length of jump is longer. For example, assuming that the screen brightness has a variation value of 20, the user may not perceive it as noticeable when the screen brightness is reduced from 200 to 180; however, when the screen brightness is reduced from 60 to 40, the user may clearly perceive that the screen brightness is getting darker. Based on such characteristics, the adjustment curve employed should have the following characteristics: when the screen brightness is bright, the slope of the curve should be large, and the change rate of the screen brightness is high; when the screen brightness is low, the slope of the curve should be low, and the rate of change of the screen brightness is low. In order to ensure that the change of the screen brightness is gradual in the process of adjusting the screen brightness, the screen brightness is realizedIn the embodiment of the invention, the screen brightness is adjusted in a linear mode. Therefore, the adjustment curve adopted in the embodiment of the present invention is the quadratic function y ═ ax2+ bx + c, where y is the screen brightness, x is the brightness adjustment time, and a, b, and c are the basic parameters of the above quadratic function.
For example, assume that the processor 13 of the handset 01 presets the browser scene and the adjustment curve 1 (i.e., y)1＝a1x1 2+b1x1+c1) Correspondingly, the video scene corresponds to the adjustment curve 2 (i.e., y)2＝a2x2 2+b2x2+c2) Correspondingly, the instant message scene and adjustment curve 3 (i.e., y)3＝a3x3 2+b3x3+c3) And (7) corresponding. After the user starts the first application and the first application is 'WeChat', the processor 13 of the mobile phone 01 determines that the application scene is an instant message scene, and the processor 13 determines that an adjustment curve corresponding to the instant message scene is y according to the determined instant message scene and the preset corresponding relationship between the instant message scene and the adjustment curve3＝a3x3 2+b3x3+c3。
And S203, the terminal equipment adjusts the screen brightness by adopting the adjusting curve corresponding to the application scene.
For example, the embodiment of the present invention may use a quadratic function y ═ ax2+ bx + c adjusts the screen brightness, and the domain of the quadratic function is [0, T]Value range of [ Bmin,Bmax]. Wherein y is the screen brightness, x is the brightness adjustment time, T is the brightness adjustment duration, BminIs a first target brightness, BmaxIs the current brightness of the first application. And, for different application scenarios, the quadratic function y ═ ax adopted by the terminal equipment2The + bx + c is different, that is, the parameters (a, b, and c) of the quadratic function are different for different application scenarios.
Specifically, the processor of the terminal device may use a quadratic function y ═ ax2+ bx + c, B for screen brightness from the beginning (time 0)maxB adjusted to time TminThe second orderThe function passes through two special points, namely (0, B)max) And (T, B)min). From the above quadratic function, the following two equations can be obtained through two special points:
Bmax＝a*02+b*0+c(1)
Bmin＝a*T2+b*T+c(2)
from equations (1) and (2), the equation can be derived: c is Bmax(3)。
Since the above-described quadratic function has monotonicity in the definition domain, the quadratic function monotonically decreases as the screen brightness decreases and monotonically increases as the screen brightness increases. From the monotonic decrease of the quadratic function in the defined domain, it can be obtained that the symmetry axis of the quadratic function is on the right of or coincides with the straight line x-T, i.e. the axis of symmetry of the quadratic function is on the right of or coincides with the straight line x-T

Suppose to get
Figure BDA0001353644370000082
The following equation can be obtained: b is-2 aT (4). Substituting equations (3) and (4) into equation (2) can yield
Figure BDA0001353644370000083
Fig. 3 is a schematic diagram of an example of the adjustment curve being a quadratic function according to the embodiment of the present invention.
This can result in: when the current brightness, the first target brightness and the brightness adjustment duration of the first application are determined, the basic parameters a, b and c of the quadratic function can be determined, so as to obtain a gradual adjustment function (i.e. quadratic function).
For example, if the application scene is a browser scene, the current brightness of the first application is 180, the first target brightness is 90, and the brightness adjustment time length is 10s, the gradual change adjustment function corresponding to the browser scene is as follows: y is 0.9x2-18x + 180. As shown in fig. 4, it is assumed that the current brightness of the browser scene, the video scene, the instant message scene, and the game scene is 180, 120, 90, and 70, respectively, the first target brightness is 90, 60, 45, and 35,the brightness adjustment duration is 10s, and then the gradual change adjustment functions corresponding to the application scenes are respectively y-0.9 x2-18x+180、y＝0.6x2-12x+120、y＝0.45x2-9x +90 and y 0.35x27x +70, corresponding to curves (a), (b), (c) and (d) shown in FIG. 4, respectively.
The adjustment curve adopted by the terminal equipment has monotonicity in the definition domain, so that the phenomenon that the screen brightness is dim and dim can not occur in the process of adjusting the screen brightness of the terminal equipment.
Of course, the method for adjusting the screen brightness provided by the embodiment of the invention can also restore the screen brightness for different application scenes. For example, the processor of the terminal device may use a quadratic function y ═ ax2+ bx + c, B for screen brightness from the beginning (time 0)minAdjusting B to restore to T timemaxThe quadratic function passes through two special points, namely (0, B)min) And (T, B)max). From the monotonic increase of the quadratic function in the defined domain, it can be obtained that the symmetry axis of the quadratic function is left of or coincides with the straight line x equal to 0, i.e. the line x is equal to 0

This gives:
Figure BDA0001353644370000092
b＝0，c＝Bmin。
for example, assuming the application scene is a browser scene, the screen brightness recovery fade adjustment function that recovers from the first target brightness 90 to the first application's current brightness 180 is: y is 0.9x2+90. As shown in fig. 5, assuming that the first target luminances of the browser scene, the video scene, the instant message scene, and the game scene are 90, 60, 45, and 35, the current luminances are 180, 120, 90, and 70, and the luminance adjustment time periods are all 10s, the screen luminance recovery gradual change adjustment functions corresponding to the application scenes are y-0.9 ×, respectively2+90、y＝0.6x2+60、y＝0.45x2+45 and y-0.35 x2+35, corresponding to curves (e), (f), (g) and (h) shown in fig. 5, respectively.
For example, assume that the current brightness of the browser scene and the video scene in the environment in which the terminal device is located is 180 and 120, respectively, and the requirements for screen brightness are 90 and 60, respectively.
In the prior art, when a first application is a browser scene, a terminal device adjusts the screen brightness in the browser scene to 90 according to the brightness of ambient light; when the first application is a video scene, the terminal device adjusts the screen brightness in the video scene to 90 according to the brightness of the ambient light. However, since the demand of the video scene for the screen brightness is 60 and the terminal device adjusts the screen brightness in the video scene to 90, a waste of power consumption of the terminal device is caused.
In the embodiment of the invention, when the first application is a browser scene, the terminal device adjusts the screen brightness to 90 by using the adjustment curve corresponding to the browser scene; when the first application is a video scene, the terminal device adjusts the screen brightness to 60 according to the adjustment curve corresponding to the video scene. It can thus be seen that: the terminal equipment in the embodiment of the invention can further reduce the power consumption of the terminal equipment.
The embodiment of the invention provides a method for adjusting screen brightness, and terminal equipment can adjust the screen brightness by adopting an adjusting curve corresponding to a determined application scene according to the application scene. Because each application scene has different requirements on the screen brightness, if the screen brightness of the terminal device is reduced only according to the change of the ambient light, and the application scene with smaller requirement on the screen brightness can cause the waste of power consumption, the terminal device in the application adjusts the screen brightness by adopting the adjusting curve aiming at different application scenes, so that the waste of the power consumption of the terminal device can be avoided, the power consumption of the terminal device is further reduced, and the endurance time of the terminal device is prolonged.
It can be seen from the above embodiments that, after the current brightness of the first application, the first target brightness, and the brightness adjustment duration are determined, the parameters a, b, and c of the quadratic function may be determined, so as to obtain an adjustment curve adopted by the terminal device. In the embodiment of the present invention, the terminal device may preset a corresponding relationship between the application scene and the brightness adjustment coefficient and a reference adjustment curve, so as to determine the first target brightness and the brightness adjustment duration.
Specifically, as shown in fig. 6, another method for adjusting screen brightness according to an embodiment of the present invention is shown, and compared with the method for adjusting screen brightness shown in fig. 2, S202 is mainly replaced with S202a and S202b, and only different places are described in detail herein, referring to fig. 6, the method for adjusting screen brightness includes:
s201, the terminal device determines an application scene according to the type of the first application.
S202a, the terminal device determines the brightness adjustment coefficient according to the application scene and the corresponding relation between the application scene and the brightness adjustment coefficient.
The brightness adjustment coefficient is used for the terminal equipment to determine the first target brightness. The application scenes correspond to the brightness adjustment coefficients one to one, that is, one application scene corresponds to one brightness adjustment coefficient. The processor of the terminal device may preset a correspondence between each application scene and the brightness adjustment coefficient, and store the correspondence in the memory.
For example, the processor of the terminal device may search for a corresponding relationship between the application scene and the brightness adjustment coefficient in the memory according to the determined application scene, and then search for the brightness adjustment coefficient corresponding to the application scene from the brightness adjustment coefficient according to the application scene and the corresponding relationship between the application scene and the brightness adjustment coefficient.
For example, the brightness adjustment coefficient in the embodiment of the present invention may be a "discount rate" of the screen brightness, the brightness adjustment coefficient corresponding to the browser scene is 0.65 (that is, the discount rate is 0.65), the brightness adjustment coefficient corresponding to the game scene is 0.9, the brightness adjustment coefficient corresponding to the video scene is 0.85, the brightness adjustment coefficient corresponding to the instant messaging scene is 0.8, the brightness adjustment coefficient corresponding to the photo scene is 0.85, and the brightness adjustment coefficient corresponding to the e-book scene is 0.7. In the embodiment of the present invention, the correspondence between each application scene and the brightness adjustment coefficient is not limited to the above correspondence, and is not listed here.
For example, the brightness adjustment coefficient in the embodiment of the present invention may be a "discount rate" of the screen brightness, and it is assumed that the processor 13 of the mobile phone 01 sets the browser scene corresponding to the brightness adjustment coefficient 1, the video scene corresponding to the second brightness adjustment coefficient 2, and the game scene corresponding to the brightness adjustment coefficient 3 in advance. After determining that the application scene is the browser scene, the processor 13 may determine that the brightness adjustment coefficient corresponding to the browser scene is 0.65 according to a preset correspondence relationship between the browser scene and the brightness adjustment coefficient (i.e., the browser scene corresponds to the brightness adjustment coefficient 3).
S202b, the terminal device determines an adjusting curve corresponding to the application scene according to the brightness adjusting coefficient and a preset reference adjusting curve.
The preset reference adjustment curve is used for the terminal equipment to determine the brightness adjustment duration.
For example, the method for determining the adjustment curve corresponding to the application scene according to the brightness adjustment coefficient and the preset reference adjustment curve by the processor of the terminal device may specifically include steps S202c, S202d, and S202 e:
s202c, the processor of the terminal device may determine the first target brightness according to the current brightness of the first application and the brightness adjustment coefficient.
Specifically, the processor of the terminal device may adopt a formula

A first target brightness is calculated, wherein,
Figure BDA0001353644370000102
as a brightness adjustment factor, BminIs a first target brightness, BmaxIs the current brightness of the first application. The processor of the terminal device may obtain the current brightness of the first application after determining the application scene.
For example, the processor 13 of the mobile phone 01 may acquire that the current brightness of the browser application is 200, and determine that the brightness adjustment coefficient corresponding to the browser scene is 0.65, and then the processor 13 may calculate that the first target brightness is 200 × 0.65 — 130.
S202d, the processor of the terminal device may determine the brightness adjustment duration according to the current brightness of the first application, the first target brightness, and a preset reference adjustment curve.
The terminal device may obtain a preset reference adjustment curve in advance. Specifically, the processor of the terminal device may determine a brightness adjustment time period T from the initial brightness adjustment to the second target brightness0And based on the starting brightness, the second target brightness and T0Determining a preset reference adjustment curve
Figure BDA0001353644370000103
Where y is the screen brightness, x is the brightness adjustment time, Δ x0Is the absolute value of the difference between the initial brightness and the second target brightness, B0The initial brightness.
Wherein, B0A second target brightness and T0All the values are experimental values which ensure that the perception of the user is small in the process of brightness adjustment, namely, under each application scene, a processor of the terminal equipment is at T0Completing screen brightness from B within time length0Adjusted to a second target brightness (e.g. B)1) The perception of the user is small.
Therefore, in order to ensure that the perception of the user is small, when the processor of the terminal device determines the brightness adjustment duration corresponding to any application scene, only the current brightness B according to the first application is ensuredmaxFirst target brightness BminAnd the slope of the linear function determined by the brightness adjustment time length T
Figure BDA0001353644370000111
And the brightness adjustment time length T can be calculated. Specifically, the linear function y ═ k × x + B crosses two special points, namely (0, B)max) And (T, B)min) Can obtain

Wherein the content of the first and second substances,

s202e, the processor of the terminal device may determine an adjustment curve corresponding to the application scene according to the current brightness of the first application, the first target brightness, and the brightness adjustment duration.
After the current brightness, the first target brightness and the brightness adjustment duration of the first application are determined, parameters a, b and c of the quadratic function can be determined.
As can be seen from the foregoing embodiments, the adjustment curve adopted by the processor of the terminal device is the quadratic function y ═ ax2+ bx + c, and
