Detailed description of the invention
For making the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and tool
Body embodiment is described in detail.
First embodiment
As it is shown in figure 1, the first embodiment of the present invention provides the method for adjustment of a kind of mobile terminal screen brightness, including:
Step 101, receives the touching of the finger of mobile phone users, gathers the fingerprint image of described finger.
In this step, mobile terminal is provided with fingerprint identification module, and its fingerprint identification module can be according to user's finger
Touching gathers the fingerprint image of finger.The design sketch of its fingerprint image, as shown in Figure 2.
Step 102, according to described fingerprint image, determines the change in location letter of the fingerprint image of the most described finger
Breath.
In this step, user can make finger occur with the touch position of fingerprint identification module by the angle adjusting finger
Change, so that the position of the fingerprint image of finger changes；Mobile terminal need to obtain the finger of the most described finger
The change in location information of print image.Concrete, its change in location information at least includes position offset and offset direction, position.
Step 103, according to the change in location information of described fingerprint image, adjusts the screen intensity of described mobile terminal.
The change in location information obtained according to step 102 in this step adjusts the screen intensity of mobile terminal, i.e. basis
Change in location increases screen intensity or reduces screen intensity.Concrete, how to adjust screen intensity, can be set in advance by user
Fixed, or preset by system, it is not especially limited at this.
To sum up, by identifying the fingerprint image of user and according to the position of fingerprint image in the first embodiment of the present invention
Change improves the method adjusting screen intensity so that user is without lighting screen, without searching the slider bar regulating brightness,
Just anywhere or anytime screen intensity can be adjusted, optimize Consumer's Experience.
Second embodiment
As it is shown on figure 3, the second embodiment of the present invention provides the method for adjustment of a kind of mobile terminal screen brightness, including:
Step 301, receives the touching of the finger of mobile phone users, gathers the fingerprint image of described finger.
In this step, mobile terminal is provided with fingerprint identification module, and its fingerprint identification module can be according to user's finger
Touching gathers the fingerprint image of finger.The design sketch of its fingerprint image, as shown in Figure 2.
Step 302, obtained described in primary importance and second moment of the first fingerprint image of finger described in the first moment
The second position of the second fingerprint image of finger.
In this step, after being engraved in for the first moment when second, the concrete interval between it is not construed as limiting.Concrete, first
First fingerprint image in moment and the fingerprint image that the second fingerprint image is same finger in the second moment.It is also preferred that the left its first
Between moment and the second moment, the finger of user is without departing from the fingerprint identification module of mobile terminal；Or when pre-setting first
Carving the maximum time interval between the second moment, i.e. in maximum time interval, user touches the fingerprint of mobile terminal for twice
Identification module.
Step 303, according to described primary importance and the described second position, determines that described second fingerprint image is relative to first
The change in location information of fingerprint image；Wherein, described change in location information includes position offset and offset direction, position.
In this step, its change in location information refers specifically to the second fingerprint image and becomes relative to the position of the second fingerprint image
Changing, i.e. the second position is relative to the position offset of primary importance and offset direction, position；The such as second position is relative to
One position has moved up 1mm etc., wherein, " on " it is offset direction, position, " 1mm " is position offset.
Step 304, according to the mapping relations of offset direction, position set in advance Yu adjustment direction, determines described mobile whole
The adjustment direction of the screen intensity of end.
In this step, user or mobile terminal need to pre-set mapping relations, specially offset direction, position and screen
Mapping relations between the adjustment direction of brightness, such as offset direction, position be " on " time, adjustment direction is " tuning up ".It is concrete
