Embodiment
In order that those skilled in the art more fully understand the present invention program, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.Obviously, described embodiment is only part of the embodiment of the present invention, rather than
Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, belongs to the scope of protection of the invention.
Referring to Fig. 1, for a kind of implementing procedure figure of camera interface access method in the present invention, this method can include following
Step：
Step S101：When the translational speed for detecting mobile terminal reaches default threshold speed, internal trigger is generated
Signal.
A threshold speed can be preset to mobile terminal, reaches default in the translational speed for detecting mobile terminal
Threshold speed when, can be regarded as having reached default trigger condition, in such a case, it is possible to generate internal trigger letter
Number.
It should be noted that threshold speed can be set and be adjusted according to actual conditions, the embodiment of the present invention is to this
Do not limit.For example, the technical scheme that the multiple embodiment of the present invention provided is performed in a certain threshold speed according to setting,
But when user is captured using mobile terminal to object, there is mobile terminal and not automatically enter the phenomenon at camera interface still
Compare frequently, then can suitably reduce the threshold speed.
Step S102：According to internal trigger signal, the acceleration signature value and angular speed characteristic value of mobile terminal are obtained.
After internal trigger signal is generated, it is probably that user needs to enter the object on periphery using mobile terminal that can prejudge
Row is taken pictures.Therefore, in such a case, it is possible to according to the internal trigger signal of generation, the acceleration signature of mobile terminal is obtained
Value and angular speed characteristic value.
Step S103：According to acceleration signature value and angular speed characteristic value, it is determined whether generation camera call signal, if
It is then to perform step S104.
, can be according to the acceleration signature of acquisition after the acceleration signature value and angular speed characteristic value of mobile terminal is obtained
Value and angular speed characteristic value, translation and the rotation situation of mobile terminal are determined, verify the user previously made possibly also with movement
Whether this anticipation that take pictures of the object on terminal-pair periphery is correct, determines whether to generate camera call signal, if really
Surely camera call signal is generated, then can continue executing with step S104.If it is determined that do not generate camera call signal, then without
Ensuing detection.

First angular speed characteristic value of the angular speed characteristic value in X-direction or the second angular speed characteristic value in Y direction of dynamic terminal
During less than default second angular speed threshold value, whether timing time is less than default very first time threshold value, that is, detects mobile terminal
Whether have from being moved to static trend, it is impossible to only judge whether that acceleration signature value is more than acceleration rate threshold and angular speed
Characteristic value is more than the situation of the first angular speed threshold value, because user is not when needing to capture object, such as user exists
When carrying mobile terminal running, it is also possible to which the acceleration signature value for mobile terminal occur is more than acceleration rate threshold and angular speed feature
Value is more than the situation of the first angular speed threshold value, and user is using mobile terminal to object when being captured, and mobile terminal is from original
Beginning, position was to the process for having deceleration in the certain time of camera site, and mobile terminal is decelerated to up to after camera site, in transverse screen
State or portrait layout state, transverse screen state are that the angle change of mobile terminal in the X-axis direction is substantially zeroed, or in a very little
In the range of change, portrait layout state is that the angle change of mobile terminal in the Y-axis direction is substantially zeroed, or in the range of a very little
Change.
It should be noted that acceleration rate threshold and the first angular speed threshold value are the value more than zero, and both can be with
Set and adjusted according to actual conditions, the embodiment of the present invention is not limited this.For example, when a certain acceleration according to setting
Degree threshold value and a certain first angular speed threshold value of setting perform the technical scheme that the multiple embodiment of the present invention is provided, but such as
Fruit appears in user when being captured using mobile terminal to object, and the phenomenon that mobile terminal not automatically enters camera interface still compares
Relatively frequently, then the acceleration rate threshold of setting or the first angular speed threshold value of setting can suitably be reduced, to reduce due to setting
Acceleration rate threshold or the first angular speed threshold value of setting are excessive, mobile when user is captured using mobile terminal to object
Terminal not automatically enters the probability at camera interface.
Explanation is needed further exist for, very first time threshold value can be set and be adjusted according to actual conditions, the present invention
Embodiment is not limited this.Carried for example, performing the multiple embodiment of the present invention in a certain very first time threshold value according to setting
The technical scheme of confession, but when user is captured using mobile terminal to object, occur due to reaching in timing time
During one time threshold, the first angular speed characteristic value in X-direction of the angular speed characteristic value of mobile terminal and in Y direction
Two angular speed characteristic values are all not less than the second angular speed threshold value, and the phenomenon that mobile terminal not automatically enters camera interface still compares frequency
It is numerous, then it can increase the very first time threshold value.
Further it should be noted that the second angular speed threshold value can be set and be adjusted according to actual conditions, this
Inventive embodiments are not limited this, for example, when a certain second angular speed threshold value according to setting performs repeatedly the present invention in fact
Apply the technical scheme that example is provided, still, when appearing in user and not using mobile terminal to capture object, it is mobile eventually
Hold the phenomenon automatically into camera interface still relatively more frequent, then can reduce the second angular speed threshold value.
In a kind of embodiment of the present invention, determine whether timing time is less than default very first time threshold value,
It may comprise steps of：
Determine whether that timing time is less than default very first time threshold value and the first angular speed characteristic value or the second angular speed
The duration that characteristic value is less than the second angular speed threshold value is more than default second time threshold.
It is determined that the acceleration signature value that mobile terminal be present is more than acceleration rate threshold and angular speed characteristic value is more than first
After the situation of angular speed threshold value, and determine to be more than acceleration rate threshold and angular speed feature from the acceleration signature value of mobile terminal
The first moment that value is more than the first angular speed threshold value starts timing, to mobile terminal angular speed characteristic value the of X-direction
One angular speed characteristic value or when the second angular speed characteristic value of Y direction is less than the second angular speed threshold value, timing time is less than
After default very first time threshold value, first jiao speed of the angular speed characteristic value in X-direction of mobile terminal may further determine that
Spend characteristic value or whether be less than the duration of the second angular speed threshold value more than default in the second angular speed characteristic value of Y direction
The second time threshold.Because user when being captured to object, may reach shooting position in mobile terminal from home position
Postpone, user wants to change screen state, such as from transverse screen State Transferring be portrait layout state, so determining it is mobile eventually
First angular speed characteristic value of the angular speed characteristic value at end in X-direction or the second angular speed characteristic value in Y direction are less than
, it is necessary to there is the wait of certain time after second angular speed threshold value.
It should be noted that the second time threshold can be set and be adjusted according to actual conditions, the embodiment of the present invention
This is not limited.For example, when a certain second time threshold according to setting of the embodiment of the present invention performs repeatedly the present invention in fact
The technical scheme that example is provided is applied, still, user from home position by mobile terminal after camera site is moved to, it is desirable to is changed
Once screen state is shot, and the phenomenon that but mobile terminal is shot to object before screen conversion frequently occurs, then may be used
To increase second time threshold.
Step S104：Camera call signal is generated, calls camera to enter camera interface using camera call signal.

Machine call signal, camera is called to enter camera interface using camera call signal.By detecting the movement of mobile terminal
When speed reaches default threshold speed, the acceleration signature value and angular speed characteristic value of mobile terminal are obtained, according to acceleration
Spend characteristic value and angular speed characteristic value is judged after generating camera call signal, camera call signal can be utilized to call camera enter
Enter camera interface, so as to when user needs to capture object, be simplified automatically into camera interface into camera
