Fig. 1 is the schematic flow sheet of the stabilization processing method of one embodiment of the application.
As it is shown in figure 1, this stabilization processing method includes:
Step 101, receives the photographing instruction of mobile terminal.
Specifically, the executive agent of the stabilization processing method that the present embodiment provides is stabilization processing means, and this stabilization processes
Device can be configured in as a example by having in the mobile terminal of camera head and be specifically described.
It should be noted that the type of mobile terminal is a lot, can select, such as according to application needs: be mobile phone, flat
Plate computer etc..
Camera head in the embodiment of the present application includes MEMS (micro electro-mechanical
System, is called for short MEMS) and imaging sensor Sensor, wherein imaging sensor is under MEMS control, by different driving electricity
Pressure drives and carries out upper and lower, the movement of left and right in a plane, or rotates.Generally, when camera head has been focused and mobile
During terminal non-jitter, the driving voltage of MEMS output is in plateau, and thus, the embodiment of the present application proposes a kind of root
Scope according to the driving voltage value place of MEMS output, it is judged that whether mobile terminal exists shake, and then selects properly
Photo opportunity, to improve the definition of the image that camera head in mobile terminal obtains.
Concrete, stabilization processing means can receive photographing instruction in several ways.
Example one:
Whether it is triggered by the button of taking pictures in monitoring mobile terminal, receives photographing instruction.
Wherein, the button of taking pictures in mobile terminal can be setting " entity snapshot button " in mobile terminal, it is also possible to
It is mobile terminal when being in exposal model, on the display screen of mobile terminal " the touch snapshot button " of display.
During taking pictures, when user presses " entity snapshot button " or taps " touch snapshot button ", stabilization
Processing means, can receive photographing instruction.
Example two:
The definition of the image obtained in the camera lens determine mobile terminal has reached the value preset, thus triggering is taken pictures and asked
Ask.
Wherein, the value preset can set according to definition values when having focused.
Concrete, stabilization processing means, the definition of the image that mobile terminal camera lens obtains can be monitored in real time, determining
When definition reaches default value, i.e. determining that focusing completes, can take pictures, now stabilization processing means can receive bat
According to instruction.
Step 102, it is judged that current time for the driving voltage value driving the MEMS of imaging sensor to export is
No in default voltage range, described MEMS is for driving described imaging sensor to compensate described mobile terminal
Shake, what wherein said MEMS exported driving voltage value is for characterizing the jitter amplitude of described mobile terminal.
Concrete, due to the different state of the different driving voltage value correspondence mobile terminal of MEMS output,
When such as mobile terminal is in dither state, MEMS output driving voltage value, be in static shape with mobile terminal
During state, what MEMS exported driving voltage value is different, therefore, exports according to MEMS in each embodiment of the application
The size of driving voltage value, judge whether mobile terminal is in dither state, and the amplitude size of shake.
Wherein, the voltage range preset, can be according to when remaining static of MEMS output, corresponding microcomputer
The driving voltage value of electricity system output determines.Such as, if when mobile terminal remains static MEMS output drive
Galvanic electricity pressure is 5 volts (V), then consider that certain measurement error or voltage instability, default voltage range can be set to
4.8V-5.2V, then when stabilization processing means detects that driving voltage that MEMS exports is between 4.8V-5.2V,
Then it is believed that mobile terminal remains static, accordingly, if detecting, the driving voltage that MEMS exports is 5.4V,
Then it is believed that mobile terminal is in dither state, be the most now not suitable for taking pictures.
Step 103, the most then control camera lens and obtain the image of current time.
Concrete, if stabilization processing means, determine driving voltage that MEMS exports in default voltage range,
I.e. mobile terminal is currently at resting state, then can control camera lens and obtain the image of current time.
It is understood that in the embodiment of the present application, according to the driving voltage value of MEMS output, it is judged that mobile whole
Whether end is in dither state, such that it is able to effectively realize the monitoring to mobile terminal dither state, and then selects suitably
Photo opportunity, thus ensure that the definition of the image got.
The stabilization processing method that the embodiment of the present application provides, first receives the photographing instruction of mobile terminal, then judges to work as
The front moment for drive driving voltage value that the MEMS of imaging sensor exports whether in default voltage range, institute
State MEMS for driving described imaging sensor to compensate the shake of described mobile terminal, wherein said MEMS
The driving voltage value of output is for characterizing the jitter amplitude of described mobile terminal；If it is determined that the driving voltage of MEMS output
In default voltage range, then control camera lens and obtain the image of current time.Hereby it is achieved that mobile terminal was being taken pictures
The effective monitoring of shake and evading in journey, and according to shake rule, reasonably select preferably photo opportunity, suitable for selecting
Photo opportunity provides condition, thus ensure that the definition of the image got.
By above-mentioned analysis, in the embodiment of the present application, can be according to the driving of current time MEMS output
Magnitude of voltage judges whether mobile terminal is in dither state, and when determining that mobile terminal is in steady statue, obtains current
The image in moment.In a kind of possible way of realization, user when hand-held mobile terminal shoots, the shake of mobile terminal
It is to be caused by the heart beating of user, and owing to the heart beating of user has certain regularity, so that the shake of mobile terminal
Also having certain regularity, accordingly, for compensating the shake of mobile terminal, the driving voltage of MEMS output also has certain rule
Property.Now, stabilization processing means, camera lens can be controlled on suitable opportunity according to the regularity of the driving voltage of MEMS output
Obtain image, below in conjunction with Fig. 2, above-mentioned situation is described in detail.
Fig. 2 is the schematic flow sheet of the stabilization processing method of another embodiment of the application.
As in figure 2 it is shown, this stabilization processing method, including:
Step 201, receives the photographing instruction of mobile terminal.
Step 202, it is judged that whether the driving voltage value that current time exports for driving the MEMS of imaging sensor is in advance
If voltage range in, the most then perform step 205, otherwise, perform step 203.
Step 203, the driving voltage waveform exported according to described MEMS, it is judged that within the first time period preset, if
There is the driving voltage value first time period in default voltage range of described MEMS output, the most then perform step
204, otherwise perform step 205.
Step 204, in described first time period, controls described camera lens and obtains image.
Step 205, controls described camera lens and obtains the image of current time.
Concrete, the shake of the mobile terminal caused due to the heart beating of user, it is generally of certain regularity, because of
This, if when receiving photographing instruction, the driving voltage value of MEMS output, can be according to MEMS not in default voltage range
The driving voltage waveform of output, it is judged that in following certain period of time, whether the driving voltage value of MEMS output is at default electricity
In the range of pressure, if, then can determine when mobile terminal can be at resting state after a certain time, then control camera lens acquisition figure
Picture.
Wherein, the first time period preset can need to be configured according to the wait of user.For example, if user etc.
Deng time more than 300 milliseconds (ms), waiting time the most long sensation i.e. can be produced, then the first time period preset i.e. may be set to
300ms。
For example, the MEMS outputting drive voltage waveform diagram that Fig. 3 provides for the embodiment of the present application.As it is shown on figure 3,
With per second as cycle, there is intermittent shake in MEMS outputting drive voltage, wherein imaging sensor the highest shake voltage is 6V,
Low jitter voltage is 4V.
If the voltage range so preset is 4.8V-5.2V, the first time period preset was 0.5s, was receiving finger of taking pictures
During the t1 made, the driving voltage value of MEMS output is 4.5V, then can be according to the driving voltage waveform of MEMS output, it is judged that
In following 0.5s, whether the driving voltage of MEMS output has the first time period in 4.8V-5.2V, according to Fig. 3, at t1
In the t2 moment after moment, the driving voltage of MEMS output is i.e. in 4.8V-5.2V, and the time in t2 moment distance t1 moment
It is spaced apart 0.4s, less than 0.5s, therefore, after the t2 moment by the time, then camera lens acquisition image can be controlled.
It should be noted that first time period can determine according to the processing speed of camera head, if receiving than camera lens
After the instruction of acquisition image, 0.1s can complete process of taking pictures, then first time period can be 0.1s, if camera lens is receiving
After obtaining the instruction of image, 0.3s could can complete to take pictures processs, then first time period can be 0.3s, i.e. needs guarantee shifting
Dynamic terminal remains static in camera lens obtains the time period of image, higher in the image definition that can guarantee that acquisition.
If it is understood that the driving voltage waveform of MEMS output is not periodic jitter waveform, then stabilization processes
Device, can directly control camera lens obtain the image of current time when receiving photographing instruction.
In a kind of possible way of realization, if the above-mentioned first time period preset is less, for example, if first presets
Time period be 0.3s, and the driving voltage of MEMS output every 1s there will be the driving voltage of 0.6s 4.8V-5.2V time
Between, i.e. the driving voltage of MEMS output, in every 1s, has driving voltage value corresponding to time of 0.4s not in 4.8V-5.2V.
If so stabilization processing means is the t3 moment as shown in Figure 3 in the moment receiving photographing instruction, and the t2 after 0.4s
During the moment, just become the driving voltage value of MEMS output can stablize 0.6s, i.e. 0.4s between 4.8V-5.2V be more than 0.3s, in order to
Reducing owing to the waiting time is long, and affect the experience of user, stabilization processing means can control camera lens and obtain current time
Image, and when no longer waiting the driving voltage of MEMS output to stablize to 4.8V-5.2V, then trigger camera lens acquisition image.
It should be noted that during actual photographed, need the judgement that drives voltage waveforms to according to MEMS output to move
Whether the shake of dynamic terminal is owing to the heart beating of user causes, and then further according to the driving voltage waveform of MEMS output, selects
Suitably photo opportunity, i.e. before above-mentioned steps 202, the present embodiment also includes:
Step 206, the driving voltage waveform of MEMS output in the second preset time period before acquisition current time.
Step 207, according to the driving voltage waveform in described second preset time period, determines that described mobile terminal is current
Whether shake is periodic jitter, the most then perform step 202, otherwise perform step 205.
Concrete, stabilization processing means, the driving voltage value of MEMS output can be monitored in real time, then receiving finger of taking pictures
When making, according to the driving voltage waveform in the time period before current time, it is judged that whether the current shake of mobile terminal
For periodic jitter, the most then may determine that current shake is caused by heart beating or other periodically ectocine, thus
The driving voltage value that can export in conjunction with the MEMS that the driving voltage waveform of MEMS output and current time are corresponding, selects a shifting
The moment control camera lens acquisition image that dynamic terminal shake is relatively light or static.
Wherein, the length of the second time period preset can determine according to user's common heart beating rule, the most generally uses
The heart beating rule at family is in each 1s, and heart beating is once, then the second time period preset needed more than at least 2 heart beat cycles
Time, such as, 3s, 5s, 6s etc. can be chosen.
The stabilization processing method of the embodiment of the present application, first receives the photographing instruction of mobile terminal, then according to time current
The driving voltage waveform of the MEMS output in the second preset time period before quarter, it is judged that what mobile terminal was current is dithered as the cycle
Property shake, judge the most again driving voltage value that current time MEMS exports whether in default voltage range, if,
Then controlling camera lens and obtain the image of current time, if not existing, then judging within the first time period preset, if there is MEMS defeated
The driving voltage value gone out first time period in default voltage range, if existing, then time in first time period, controls institute
State camera lens and obtain image, if not existing, controlling camera lens the most again and obtaining the image of current time.Hereby it is achieved that to mobile terminal
The effective monitoring of shake during taking pictures, and reasonably select preferably photo opportunity according to shake rule, thus ensure that
The definition of the image got.
In a kind of possible way of realization, if the driving voltage of MEMS output is cyclic fluctuation form, and receiving
In the time period that after photographing instruction first is preset, the driving voltage of MEMS output can not be stablized in default voltage range,
So stabilization processing means, it is also possible in judging the time period that first after current time is preset, if there is MEMS defeated
The driving voltage gone out is less than the second time period of the driving voltage of current time, if existing, then just within the second time period, and control
Camera lens processed obtains image.
For example, if the driving voltage of MEMS output is as it is shown on figure 3, receive photographing instruction in the t3 moment, when
The driving voltage V1 of front moment MEMS output is not in default voltage range, and after the t2 moment, the driving of MEMS output is electric
Pressure just can be stablized in default voltage range, and the time difference of t3 to t2, and the time that can receive more than user waits until, that
Stabilization processing means, i.e. can determine whether within the t3-t2 time period, if there is the driving voltage of MEMS output than current time
The situation that driving voltage V1 is low, according to Fig. 3, within the t4-t5 time, driving voltage the driving than current time of MEMS output
Pressure V1 is low for galvanic electricity, and i.e. within the t4-t5 time, the shake of mobile terminal is lower than the jitter amplitude of current time, i.e. to the shadow taken pictures
Ring less than current time, therefore, camera lens can be controlled and obtain image within the t4-t5 time.Thus, ensure that camera lens obtains as far as possible
Take the definition of image.
