Power consumption of operating mode when being worked it is different, avoid gyroscope in different scene types with the Working mould of higher power dissipation
Formula works, and reduces the power consumption of gyroscope.
In one embodiment, according to scene type from the corresponding relationship of scene type and the operating mode of gyroscope,
Determine corresponding operating mode, comprising: when the scene type of image is the first scene type, according to the first scene type from field
In the corresponding relationship of the operating mode of scape classification and gyroscope, corresponding first operating mode is determined；When the scene type of image

In the running parameter of present gyroscope, such as vibration frequency, frequency acquisition, measurement direction, measurement range.When the vibration of gyroscope
Frequency is higher, then the precision of the angular velocity data of gyroscope acquisition is smaller, i.e., angular velocity data is more accurate, and the performance of gyroscope is got over
The power consumption of height, gyroscope is also higher.When the sample frequency of gyroscope is higher, then the angular speed that gyroscope acquires within the unit time
Data are more, and the performance of gyroscope is higher, and the power consumption of gyroscope is also higher.
In one embodiment, the first scene type can be text scene type.When user shoots text, such as shoot
When one article, the fine jitter of electronic equipment may make the image Chinese type matrix of shooting to paste, to not see Chu's shooting
Word content.Therefore, when the scene type of image is text scene type, the performance of gyroscope is higher can to make electronic equipment
Jitter compensation is more accurately carried out, to obtain the image being more clear.
In one embodiment, the first scene type can also be portrait scene type.When user shoots people, such as shoot
When face, need to guarantee the clarity of the human face region of shooting.Therefore, when the scene type of image is behaved as scene type,

In one embodiment, the second scene type can be landscape scene type.When user shoots landscape, such as shoot
When high mountain and great rivers, the object of shooting generally apart from electronic equipment farther out, then electronic equipment is under fine jitter, and gyroscope is with lower
Performance acquire angular velocity data, electronic equipment can also according to the angular velocity data carry out jitter compensation, it is still available
More visible image.Therefore, when the scene type of image is landscape scene type, the performance of gyroscope can be lower, thus
Reduce the power consumption of gyroscope.
In one embodiment, the second scene type can be scene type on daytime.It is understood that being shot at night
When image, the light information that electronic equipment obtains is less, then the fine jitter of electronic equipment will cause the image more mould of shooting
Paste.And when shooting image daytime, the light information that electronic equipment obtains is more, though electronic equipment there are fine jitter,
More visible image can be obtained.Therefore, when the scene type of image is scene type on daytime, the performance of gyroscope can be compared with
It is low, to reduce the power consumption of gyroscope.
In one embodiment, electronic equipment can increase default scene type, such as third scene type；Then the first scene
The performance of classification, the second scene type and the corresponding gyroscope of third scene type successively improves, work in the first scene type,
The power consumption of second scene type and the corresponding gyroscope of third scene type is sequentially increased.
Above-mentioned gyroscope processing method determines that gyroscope is corresponding when the scene type of image is the first scene type
Operating mode is the first operating mode；When the scene type of image is the second scene type, the corresponding work of gyroscope is determined
Mode is the second operating mode.The performance for working in the gyroscope of the first operating mode is higher, and electronic equipment can be according to work
In the angular velocity data that the gyroscope of first mode obtains, more accurate image is obtained；Work in the top of the second operating mode
The performance of spiral shell instrument is lower, can reduce the power consumption of gyroscope.
In one embodiment, operating mode includes the running parameter for configuring gyroscope, and the running parameter of gyroscope includes
At least one of vibration frequency and the sample frequency of gyroscope of gyroscope；The vibration frequency of the gyroscope of first operating mode is high
In the vibration frequency of the gyroscope of the second operating mode；The sample frequency of the gyroscope of first operating mode is higher than the second Working mould
The sample frequency of the gyroscope of formula.
Vibration frequency refers to the number of vibration each second.Sample frequency refers to obtaining first jiao of speed gyroscope each second
The number of degree evidence.
The performance of the corresponding gyroscope of first scene type is higher than the performance of the corresponding gyroscope of the second scene type, because
This, the vibration frequency of the gyroscope of the first operating mode is higher than the vibration frequency of the gyroscope of the second operating mode.Work as gyroscope
Vibration frequency it is higher, smaller shake can be measured, the precision of the angular velocity data of acquisition is also smaller, i.e. the performance of gyroscope
It is higher.The sample frequency of the gyroscope of first operating mode is higher than the sample frequency of the gyroscope of the second operating mode.
When the sample frequency of gyroscope is higher, i.e., gyroscope obtains more angular velocity datas, gyro within the unit time
The real-time that instrument measures the shake of electronic equipment is more preferable, i.e. the performance of gyroscope is higher.
It should be pointed out that the running parameter of gyroscope can also include measurement range, measurement direction etc., specific work
Parameter can be set according to user, without being limited thereto.
Above-mentioned gyroscope processing method, operating mode include the running parameter for configuring gyroscope, the running parameter of gyroscope
It may include at least one of vibration frequency and the sample frequency of gyroscope of gyroscope；The vibration of the gyroscope of first operating mode
Dynamic frequency is higher than the vibration frequency of the gyroscope of the second operating mode；The sample frequency of the gyroscope of first operating mode is higher than the
The sample frequency of the gyroscope of two operating modes.The performance for then working in the gyroscope of the first operating mode is higher, works in
The power consumption of the gyroscope of two operating modes is lower.
As shown in figure 4, in one embodiment, above-mentioned gyroscope processing method further include:
Step 402, the first angular velocity data acquired when gyroscope work is obtained.
Angular speed refers to describing the angle turned within the unit time when object rotation and rotation in physics
The vector in direction.First angular velocity data refers to the direction of the angle that electronic equipment turns within the unit time and rotation.
First angular velocity data is bigger, indicates that the angle of electronic equipment rotation is bigger, the direction of rotation is bigger, then the shake of electronic equipment
It is bigger.
Step 404, when the first angular velocity data is greater than or equal to the first angular speed threshold value, the vibration frequency of gyroscope is reduced
Rate.
Vibration frequency refers to the number of vibration each second.It is illustrated in figure 5 the structural schematic diagram of MEMS gyroscope.MEMS
Gyroscope, which is constantly vibrated by two and constantly done heterodromous block 502 and 504, to be formed.When detecting shake, also
It is the power of Coriolis effect F generation opposite direction when applying angular velocity vector Ω, on each block, so as to cause capacitance variations.
Capacitive differential is directly proportional to angular speed, therefore, may know that angular speed at this time by the variation of measurement capacitance, so as to
Get the first angular velocity data.Vibration frequency is the number that each block each second is vibrated in MEMS gyroscope.Each
The vibration frequency of block is identical.
As shown in fig. 6, the Coriolis force formula of gyroscope is as follows when gyroscope detection electronic equipment shake:
Wherein,It is the base vector of three axis of Space Rotating coordinate system.R refers to that moving radius, ω are
Angular speed, vrIt is radial motion speed, arIt is radial acceleration, aCoriolisIt is Coriolis force acceleration.
By above formula it is found that working as Coriolis force aCoriolisWhen constant, for lesser shake i.e. lesser
For angular speed, big radial motion speed v is neededrIt can be only achieved the precision of gyroscope, and radial motion speed vrWith vibration
Frequency is proportional.That is, gyroscope needs higher vibration frequency, lesser shake can be just detected.Work as gyro
When the vibration frequency of instrument is higher, biggish power consumption is also produced.
It is understood that indicating electronic equipment when the first angular velocity data is greater than or equal to the first angular speed threshold value
Shake it is larger.And the size of the vibration frequency of gyroscope and gyroscope can be detected the size of the shake of electronic equipment at
It is negatively correlated.Therefore, when the shake of electronic equipment is larger, even if the lesser vibration frequency of gyroscope may also detect that electronics is set
Standby shake, to collect correct first angular velocity data.When reducing the vibration frequency of gyroscope, top can be reduced
The power consumption of spiral shell instrument, to save the resource of electronic equipment.
Step 406, when the first angular velocity data is less than the first angular speed threshold value, the vibration frequency of gyroscope is improved.
When the first angular velocity data is less than the first angular speed threshold value, indicates that the shake of electronic equipment is smaller, can be improved
The vibration frequency of gyroscope allows gyroscope to measure more small shake, improves the accurate of the angular velocity data of acquisition
Property.
The vibration frequency that gyroscope is adjusted according to the first angular velocity data can also improve the model of gyroscope measurement shake
It encloses.For example, the range of the shake that can be measured is 2 degree or more when the vibration frequency of gyroscope is 100Hz, then when according to the
The vibration frequency that one angular velocity data adjusts gyroscope is 150Hz, and the range for the shake that can be measured is 1 degree or more, then adjusts
Gyroscope afterwards can measure more small shake, improve the range of the measurement shake of gyroscope.
Above-mentioned gyroscope processing method obtains the first angular velocity data acquired when gyroscope work, when the first angular speed
When data are greater than or equal to the first angular speed threshold value, the vibration frequency of gyroscope is reduced, the power consumption of gyroscope can be reduced；When
When one angular velocity data is less than the first angular speed threshold value, the vibration frequency of gyroscope is improved, the angle of gyroscope acquisition can be improved
The accuracy of speed data.
As shown in fig. 7, in one embodiment, above-mentioned gyroscope processing method further include:
Step 702, at least one of location information and the application program of unlatching are obtained.

The satellite systems such as Beidou or network are positioned to obtain to electronic equipment.
In the electronic device, various application programs can be downloaded, and more and more application programs can open camera shooting
Head obtains image, carries out Video chat as social category application program can open camera, scanning class application program can be opened
Camera is scanned acquisition image, and short video application can open camera recorded video etc..
Step 704, it is determined according to the scene type of at least one of location information and the application program of unlatching and image
