When mobile terminal is in static condition, carry out step 3013, when mobile terminal is not in static condition, carry out step 3014.
Step 3013, determines that mobile terminal is in the state of buckling.
Step 3014, determines that mobile terminal is not in the state of buckling.
Like this, user is when using mobile terminal, and mobile terminal is in mode of operation, after detecting that movement turns by user, then determines whether mobile terminal is static condition, thus can determine that user does not re-use this terminal, can enter energy-saving mode.
As shown in Fig. 3-3, in another kind of implementation, judge whether mobile terminal is in the process presetting economize on electricity trigger state and can comprises:
Step 3015, judges whether mobile terminal is in static condition.When mobile terminal is not in static condition, perform step 3016, when mobile terminal is in static condition, perform step 3017.
Example, judge that the process whether mobile terminal is in static condition can comprise: the value gathering m dynamic parameter of mobile terminal in preset time period, m is more than or equal to 1, and this dynamic parameter can comprise: at least one in the horizontal velocity in the vertical speed of mobile terminal on gravity direction (also claiming vertical direction), vertical acceleration, in the horizontal direction (direction vertical with gravity direction) on gravity direction, horizontal acceleration in the horizontal direction; When the value of m dynamic parameter is 0, determine that mobile terminal is in static condition; Exist in the value of m dynamic parameter be not 0 value time, determine that mobile terminal is not in static condition.
In embodiments of the present invention, when dynamic parameter is the vertical speed of mobile terminal on gravity direction, the value of the m of mobile terminal in preset time period vertical speed is 0, illustrate that mobile terminal no longer moves on gravity direction, now, static condition in the embodiment of the present invention can think the static condition of mobile terminal on gravity direction, in practical application, the value of this m dynamic parameter can be the dynamic parameter in a continuous print m moment, also can be the dynamic parameter in m moment of dispersion, the embodiment of the present invention limit this.Further, in order to effectively ensure that mobile terminal is in static condition on gravity direction, dynamic parameter can comprise the vertical speed of mobile terminal on gravity direction and the vertical acceleration on gravity direction, when the value of the m of mobile terminal in preset time period vertical speed and m vertical acceleration is 0, determine that mobile terminal is in static condition.Can ensure that mobile terminal did not both move at gravity direction like this, trend not dynamic on gravity direction again, determines that mobile terminal is in the static condition on gravity direction exactly.
In embodiments of the present invention, when dynamic parameter is mobile terminal horizontal velocity in the horizontal direction, the value of the m of mobile terminal in a preset time period horizontal velocity is 0, illustrate that mobile terminal no longer moves in the horizontal direction, now, static condition in the embodiment of the present invention can think mobile terminal static condition in the horizontal direction, in practical application, the value of this m dynamic parameter can be the dynamic parameter in a continuous print m moment, also can be the dynamic parameter in m moment of dispersion, the embodiment of the present invention limit this.Further, in order to effectively ensure that mobile terminal is in static condition in the horizontal direction, dynamic parameter can comprise the horizontal velocity of mobile terminal on gravity direction and the horizontal acceleration on gravity direction, when the value of the m of mobile terminal in a preset time period horizontal velocity and m horizontal acceleration is 0, determine that mobile terminal is in static condition.Can ensure that mobile terminal did not both move in the horizontal direction like this, trend not dynamic in the horizontal direction again, determines that mobile terminal is in the static condition in horizontal direction exactly.
When dynamic parameter comprises: the vertical speed of mobile terminal on gravity direction, vertical acceleration on gravity direction, horizontal velocity in the horizontal direction and horizontal acceleration in the horizontal direction time, the static condition determined belongs to absolute static condition, its defining method can with reference to said process, and the embodiment of the present invention repeats no more.
Step 3016, determines that mobile terminal is not in the state of buckling.
Step 3017, judges whether mobile terminal is oppositely placed.When mobile terminal backward is placed, perform step 3018.When the non-return placement of mobile terminal, perform step 3019.
In embodiments of the present invention, judge that the method whether mobile terminal is oppositely placed can have multiple, the embodiment of the present invention can implementation be described for following three kinds:
In implementation, can judge that the process whether mobile terminal is oppositely placed can comprise at the first:
Steps A 1, by being arranged on the light intensity of optical sensor perception through the light of screen at inside screen or screen rear.
In the embodiment of the present invention, mobile terminal at least comprises screen and back cover, this screen and back cover can surround closed cavity, the modules such as processing module can be provided with in this cavity, optical sensor sense can be integrated in screen, also screen rear can be arranged on, namely in cavity, for the outside light intensity through screen of perception mobile terminal.
Steps A 2, compares the size of light intensity through the light of screen and default Intensity threshold.When the light intensity of light is less than default Intensity threshold, perform steps A 3, when the light intensity of light is more than or equal to default Intensity threshold, perform steps A 4.
Steps A 3, determines that mobile terminal backward is placed.
Steps A 4, determines the non-return placement of mobile terminal.
Light intensity is the abbreviation of luminous intensity, international unit is that candela (candela) writes a Chinese character in simplified form cd, in correlation technique, 1cd and 1000mcd refers to the light of monochromatic source, in given directions (the party's radiation intensity is upwards (1/683) watt/surface of sphere)) the luminous flux that sends of unit solid angle.Can calculate by Kirchhoff integral theorem.In embodiments of the present invention, default Intensity threshold is generally a very little value, close to 0.
In embodiments of the present invention, when the light intensity of optical sensor perception through the light of screen by being arranged on inside screen or screen rear, when light intensity through the light of screen is less than default Intensity threshold, can think that the light of mobile terminal outside cannot through screen, account for screen may be blocked by some objects, the embodiment of the present invention thinks that now mobile terminal is buckled on placed side, is in the state of buckling.
In addition, it is worth mentioning that, for some current mobile terminals, screen periphery on the front panel of this mobile terminal is just provided with optical sensor, optical sensor such as above screen near camera, the intensity (or brightness) of the light of current environment can be obtained by this optical sensor, and the intensity (or brightness) of this light is compared with preset value, when the light intensity (or brightness) of light is less than preset value, determine that mobile terminal backward is placed, when the light intensity (or brightness) of light is more than or equal to preset value, determine the non-return placement of mobile terminal, therefore also may be used for judging whether mobile terminal is oppositely placed.
In implementation, can judge that the process whether mobile terminal is oppositely placed can comprise at the second:
Step B1, by being arranged on the light intensity of optical sensor perception through the light of screen at inside screen or screen rear.
In the embodiment of the present invention, mobile terminal at least comprises screen and back cover, this screen and back cover can surround closed cavity, the modules such as processing module can be provided with in this cavity, optical sensor sense can be integrated in screen, also screen rear can be arranged on, namely in cavity, for the outside light intensity through screen of perception mobile terminal.
Step B2, by the light intensity of the light of the optical sensor perception mobile terminal outside of the back cover or side that are arranged on mobile terminal.
Step B3, calculates the light intensity of the light of mobile terminal outside and the difference through the light intensity of the light of screen.
Step B4, compare the size of this difference and default light intensity difference.When difference is greater than default light intensity difference, perform step B5, when difference is less than or equal to default Intensity threshold, perform step B6.
Step B5, determines that mobile terminal backward is placed.
Step B6, determines the non-return placement of mobile terminal.
In embodiments of the present invention, presetting light intensity difference can be the light intensity of the light moving exterior of terminal when mobile terminal is in normal operating condition and the difference through the light intensity of the light of screen, because mobile terminal is when normally using, screen and back cover are all in non-occlusion state, the light intensity of the surround lighting of its outside perceived is substantially identical, therefore, preset light intensity difference less, level off to 0.When the light intensity being compared the light obtaining mobile terminal outside by step B4 is greater than default light intensity difference with the difference through the light intensity of the light of screen, there is certain light intensity difference in account for screen and back cover, and the light intensity of the surround lighting of outside that back cover perceives is greater than mobile terminal, can think that the light of mobile terminal outside cannot through screen, account for screen may be blocked by some objects, the embodiment of the present invention thinks that now mobile terminal is buckled on placed side, is in the state of buckling.
In implementation, can judge that the process whether mobile terminal is oppositely placed can comprise at the third:
Step C1, obtains the light direction of the screen of mobile terminal, and this light direction is the direction of the light of mobile terminal inside injection, and light direction falls in the exiting surface in screen, and points to outside screen.
As shown in Figure 3-4, Fig. 3-4 is the end view of the mobile terminal 0 shown in Fig. 1, and this mobile terminal 0 is made up of back cover 01 and screen 02, and as shown in Fig. 3-3, the exiting surface of screen is W, and light direction x falls in the exiting surface W in screen 02, and points to outside screen 02.
Step C2, detects whether light direction and gravity direction point to the same side of the exiting surface of the screen of mobile terminal.
In the embodiment of the present invention, by detecting that the same side whether light direction and gravity direction point to the exiting surface of the screen of mobile terminal judges whether mobile terminal is oppositely placed.Detect that the method whether light direction and gravity direction point to the same side of the exiting surface of the screen of mobile terminal can have multiple.Example, detect whether light direction and gravity direction point to the same side of the exiting surface of the screen of mobile terminal, comprising:
Step C21, obtains the angle of light direction and gravity direction.
As in Figure 3-5, Fig. 3-5 buckles view for the mobile terminal 0 shown in Fig. 1, mobile terminal 0 buckles on the K of placed side, this placed side K can be the placed side of desktop, bed surface and other types, and this placement can be plane or curved surface, is preferably plane, the embodiment of the present invention does not limit this, as in Figure 3-5, now light direction x is parallel with gravity direction g for light direction x and gravity direction g, and the two angle is 0.
It should be noted that, the angle of light direction and gravity direction can be obtained by angular transducer measurement, and this angle measuring sensor can be gyroscope.
Step C22, when angle belongs to default angular range, determines that light direction and gravity direction are positioned at the same side of the exiting surface of the screen of mobile terminal, and default angular range is positioned at and is more than or equal to 0 and is less than 90 degree.
As in Figure 3-5, the angle of light direction x and gravity direction g is 0, belongs to default angular range, and therefore light direction and gravity direction are positioned at the same side of the exiting surface of the screen of mobile terminal.
Step C23, when angle does not belong to default angular range, determines that light direction and gravity direction are not positioned at the same side of the exiting surface of the screen of mobile terminal.
Step C3, when light direction and gravity direction are positioned at the same side of the exiting surface of the screen of mobile terminal, determines that mobile terminal backward is placed.
Step C4, when light direction and gravity direction are not positioned at the same side of the exiting surface of the screen of mobile terminal, determines the non-return placement of mobile terminal.
Step 3018, determines that mobile terminal is in the state of buckling.
Step 3019, determines that mobile terminal is not in the state of buckling.
In practical application, step 3015 and 3016 can not be performed, directly perform step 3017 to 3018, namely determine that the mobile terminal oppositely placed is in the state of buckling, and do not need to determine whether it is standing.
Second aspect, when default economize on electricity trigger state is screen covering state, judges whether mobile terminal is in the process presetting economize on electricity trigger state and can comprises:
