Fig. 3, Fig. 3 are the plane coordinates schematic diagrames for another embodiment of method that fingerprint maloperation is prevented shown in Fig. 2.Terminal 100 is in hand
Hold general keep level under state, terminal 100, which is in non-hand holding state and can be understood as terminal 100, is in non-standard state, example
Such as, after terminal 100 is placed in into horizontal table top stabilization, the acceleration X and movable acceleration Y moved left and right is 0, weight
The numerical value of power acceleration is 9.8m/s2, it is 9.8m/s that now the acceleration Z of vertical direction value, which is approximately equal to acceleration of gravity,2。
Based on above-mentioned principle, when terminal 100 is horizontal positioned, the acceleration X and movable acceleration Y that move left and right
Equal to 0, the acceleration Z of vertical direction is equal to 9.8m/s2；
When terminal 100 is placed vertically, the acceleration X and the acceleration Z of vertical direction that move left and right are equal to 0, front and rear shifting
Dynamic acceleration Y is equal to 9.8m/s2；
When the side direction of terminal 100 is placed, the acceleration Z of movable acceleration Y and vertical direction is equal to 0, left and right
Mobile acceleration X is equal to 9.8m/s2。
Therefore a simple algorithm, which can be done, realizes gravity dynamometer, and terminal 100 obtains the acceleration now moved left and right
Degree X, movable acceleration Y and vertical direction acceleration Z value to judge the angle of inclination of terminal 100.
In this step S22, ambient brightness can be obtained by the light sensor in terminal, specifically, terminal 100
General surrounding environment light is brighter under hand holding state, and general surrounding environment light is than dark under non-hand holding state, for example, working as terminal
100 in trouser pocket when, in surrounding environment light than dark state, light sensor collection in terminal 100 is current
Ambient light is ambient brightness, is set in terminal 100 and judges whether surrounding environment light is defined as than dark intensity of illumination threshold value bar
Part, intensity of illumination, abbreviation illumination, refer to the luminous flux that visible ray is received in unit area, for indicating the power and thing of illumination
The amount of the illuminated degree of body surface area, unit lux (Lux or Lx).Illumination threshold value in setting terminal 100 is 5LX, i.e.,：
When the illumination intensity value of ambient brightness is more than 5LX, the illumination intensity value of ambient brightness can be 5.5LX, 6LX,
10LX, 100LX, 450LX, 1000LX, 10000LX etc., now judge that surrounding environment light is brighter, that is, judges terminal 100 for hand
Hold state；
When the illumination intensity value of ambient brightness is not more than 5LX, the illumination intensity value of ambient brightness can be 4.5LX,
4LX, 3.5LX, 3LX, 2.5LX, 2LX etc., now judge that surrounding environment light than dark, that is, judges terminal 100 for non-hand holding state.
Therefore, whether illumination threshold value can be more than by judging the illumination intensity value of ambient brightness to judge surrounding environment light
Whether than dark.
S23, judges whether angle of inclination, ambient brightness match with preparatory condition.
After getting angle of inclination and ambient brightness in present embodiment step S22, judge the two whether with default bar
Part matches.It is similar with above-mentioned embodiment, when preparatory condition corresponds to user's progress fingerprint recognition maloperation in present embodiment
Terminal state in which, i.e. preparatory condition are defined as terminal and are in non-hand holding state.
Specifically, preparatory condition can be that the angle of inclination of terminal is more than angle of inclination threshold value, and ambient brightness is less than ring
Border luminance threshold, wherein, angle of inclination is angle of inclination of the display surface with respect to ground level of terminal 100, when angle of inclination is more than
During the threshold value of angle of inclination, it is believed that terminal is likely to be at non-hand holding state.For example, if angle of inclination threshold value is 60 °, i.e. angle of inclination
At 60 °~90 °, it is believed that terminal is likely to be at non-hand holding state, and now, terminal 100 is likely located in pocket, and terminal 100 can
It can place vertically, it is also possible to what side direction was placed.And when terminal 100 is in hand holding state and needs unlocked by fingerprint,
The mean level of terminal 100 is placed or convergence is horizontal positioned, and its display surface is less than angle of inclination relative to the angle of inclination of ground level
Threshold value.Therefore, it is gravity sensor in terminal obtains first in above-mentioned steps S22 the acceleration X moved left and right, movable
Acceleration Y, the acceleration Z value of vertical direction judge the placement direction of terminal 100, so as to obtaining the inclination of terminal 100
Angle, then judges whether the angle of inclination of terminal 100 is more than angle of inclination threshold value.
Specifically, when acceleration of the acceleration X moved left and right the and movable acceleration Y equal to 0, vertical direction
Z is equal to 9.8m/s2When, it can determine whether out, terminal 100 is horizontal positioned, and now, the display surface of terminal 100 is relative to ground level
Angle of inclination be 0 degree, less than angle of inclination threshold value, therefore can determine whether out that terminal 100 is hand holding state.
It is equal to when the acceleration X and the acceleration Z of vertical direction moved left and right is equal to 0, movable acceleration Y
9.8m/s2When, can determine whether out, terminal 100 is placed vertically, be it is non-horizontal positioned, now, the display surface phase of terminal 100
Angle of inclination for ground level is 90 degree, more than angle of inclination threshold value, therefore judges that terminal 100 may be non-hand holding state
's.
When the acceleration X that movable acceleration Y and vertical direction acceleration Z is equal to 0, moves left and right is equal to
9.8m/s2When, can determine whether out, terminal 100 be side direction place, be it is non-horizontal positioned, now, the display surface of terminal 100
It is 90 degree relative to the angle of inclination of ground level, more than angle of inclination threshold value, therefore judges that terminal 100 may be non-hand-held shape
State.
Also included ambient brightness is less than ambient brightness threshold value in preparatory condition, and wherein ambient brightness is that current light is strong
Degree, abbreviation illumination, refers to the luminous flux that visible ray is received in unit area, for indicating the power and body surface area quilt of illumination
The amount of lighting level, unit lux (Lux or Lx).When the illumination intensity value of the ambient brightness of terminal is less than ambient brightness threshold value
When, it can determine whether out whether terminal is in non-hand holding state.
Specifically, it is 5LX to set illumination intensity value corresponding to the ambient brightness threshold value of terminal 100, in above-mentioned steps S22
The illumination intensity value for the ambient brightness that light sensor in terminal 100 obtains is matched with ambient brightness threshold value：Work as environment
When the illumination intensity value of brightness is 4.5LX, 4LX, 3.5LX, 3LX, 2.5LX, 2LX etc., the illumination intensity value of ambient brightness is less than
Ambient brightness threshold value 5LX, it is non-hand-held for can determine whether out terminal 100；
When the illumination intensity value of ambient brightness is 5.5LX, 6LX, 10LX, 100LX, 450LX, 1000LX, 10000LX,
The illumination intensity value of ambient brightness is more than environment illumination intensity threshold value 5LX, you can it is hand-held to judge terminal 100.
In this step S23 to angle of inclination, whether ambient brightness matches with preparatory condition judges, respectively by above-mentioned step
The angle of inclination obtained in rapid S22 is compared with the threshold value of angle of inclination, and by the illumination intensity value and environment of ambient brightness
Luminance threshold is compared, to judge whether to match.If matching, then it is assumed that terminal 100 is now in non-hand holding state, performs step
Rapid S24, if mismatching, then it is assumed that terminal 100 is now in hand holding state, performs step S25.
