Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and be not considered as limiting the invention.
Below with reference to the accompanying drawings shooting light-regulating method, device and the mobile terminal of the embodiment of the present invention described.
Fig. 1 is the flow chart of shooting light-regulating method according to an embodiment of the invention, as shown in figure 1, this method
Including：
Whether the light difference in S110, detection shooting picture meets preset trigger condition.
Generally, the shooting light-regulating method that the present embodiment is provided is configured in the terminal device with shoot function.
For example：In using digital camera, the scene of the mobile terminal shooting picture such as smart mobile phone, if light in shooting picture compared with
Bright, the image exposure for being likely to result in shooting is excessive, and bright region does not have level or details in the image of shooting, if shooting picture
Dark in face, the image exposure for being likely to result in shooting is not enough, causes the dark field color in shooting image dark,
The color and luster of scenery can not truly be reflected.
Thus, in order to which the image to shooting is suitably exposed so that the scenery in image can clearly be debated, the present invention is real
The shooting light-regulating method of example is applied, when the light intensity difference in shooting environmental is larger, the side for being adapted to shooting is actively selected
To the direction for selecting light intensity difference little as far as possible is shot.
Specifically, in actual implementation process, preset one and determine the whether larger triggering of light difference in shooting picture
Whether condition, preset trigger condition is met by the light difference detected in shooting picture, to judge the light in shooting picture
Whether difference is larger.
It should be noted that setting different trigger conditions according to the difference of concrete application demand, it is illustrated below：
The first example, the preset trigger condition can be default light luminance value, can by detecting shooting picture,
It is more than the light in the spot light of the light intensity value in the preset trigger condition, detection shooting picture with the presence or absence of light luminance value
Whether line difference meets preset trigger condition.
Specifically, the light luminance threshold value related to picture quality exposure effect that can be demarcated according to many experiments, and then
The light luminance of each spot light in shooting picture is detected, whether know by detection in shooting picture has bright more than default light
The spot light of threshold value is spent, determines whether the light difference in shooting picture is larger.
Second of example, the preset trigger condition can be default levels of exposure, can be by detecting shooting picture
Whether levels of exposure gap is more than default levels of exposure in the preset trigger condition, detects that the light difference in shooting picture is
It is no to meet preset trigger condition.
Specifically, due to exposure realized by shutter and aperture, thus can be based on exposure shutter and light
Circle value presets levels of exposure during shooting picture, and the fast gate value and f-number of the exposure higher grade that more exposes completely.
So as to which after the photometric data during shooting picture is known in detection, associative processor can be calculated according to photometric data
In shooting picture, the fast gate value and f-number of the exposure in each region, and determined according to the fast gate value and f-number of the exposure
Levels of exposure.
Thus, can be by judging in shooting picture, each regional exposure rank difference judges to shoot away from whether predetermined threshold value is more than
Whether the light difference in picture meets preset trigger condition.
Wherein, the predetermined threshold value of above-mentioned levels of exposure gap value is demarcated according to many experiments, if levels of exposure is poor
It is more than predetermined threshold value away from value, then shows that the light difference in shooting picture is big, if levels of exposure gap value is not more than default threshold
Value, then show that the light in shooting picture is evenly distributed.
S120, if detection light difference meets preset trigger condition, triggering MEMS is by imaging sensor from first
The four direction movement progress light-metering vertically and horizontally respectively of beginning position.
Specifically, if detection light difference meets preset trigger condition, the light in current detection shooting picture is shown

, wherein it is desired to explanation, according to the difference of concrete application demand, above-mentioned MEMS controls imaging sensor from initial
Position, when the movement of four direction vertically and horizontally of level carries out light-metering respectively, controls the order of imaging sensor moving direction
And step-length etc., it can be demarcated, also can be voluntarily set according to demand by user according to lot of experimental data by system.
S130, if detection knows that the difference of the light luminance and the light luminance in other three directions of first direction is more than
Predetermined threshold value, then control MEMS that imaging sensor is moved into the direction relative with first direction and shot.
Specifically, in one embodiment of the invention, if detection know the light luminance of first direction with other the
The difference of the light luminance in three directions is more than predetermined threshold value, then shows the light luminance and other area differentiations of first direction
Larger, the exposure effect to other regions may be influenceed by the region shoot, thus control MEMS by image
Sensor is moved to the direction relative with first direction and shot.
It should be noted that above-mentioned predetermined threshold value be demarcated according to many experiments, with picture quality exposure effect phase
The light luminance value of pass.
Wherein, the either direction that first direction can move horizontally for imaging sensor, other three directions are and first
Other different three directions of the direction in direction, it is relative to be reversed the opposite direction relative with first direction, such as, if first is anti-
During to for right, then other three directions be left, above and below, the direction relative with first direction is left etc..
For example, as shown in figure 4, when being left direction in a first direction, if the light luminance of left direction is known in detection
With other three directions, i.e., to the right, the difference of downward and upward light luminance be more than predetermined threshold value, then imaging sensor
The light luminance of initial position left and other area differentiations are larger, and carrying out shooting in the region may influence to other regions
Exposure effect, thus control MEMS imaging sensor is moved to, the direction of initial position to the right is shot.
In summary, whether the light difference in the shooting light-regulating method of the embodiment of the present invention, detection shooting picture
Preset trigger condition is met, if detection light difference meets preset trigger condition, MEMS is triggered by imaging sensor
From initial position, four direction movement carries out light-metering vertically and horizontally respectively, and then if detection knows that the light of first direction is bright
The difference of degree and the light luminance in other three directions is more than predetermined threshold value, then controls MEMS to move imaging sensor
The direction relative with first direction is moved to be shot.Thus, the active detecting light luminance when shooting, and by imaging sensor
It is moved to the suitable direction of light to be shot, improves the exposure effect of shooting image.
Based on above example, it should be appreciated that divide imaging sensor from initial position in triggering MEMS
Four direction movement is not carried out after light-metering vertically and horizontally, and obtained photometry result has diversity, except above-mentioned steps S130
Described in one of direction and other three directions light luminance difference it is larger except in the case of, it is also possible to occur in which
Any two direction situation larger with the difference of the light luminance in other directions etc..
