The embodiment of the invention discloses a kind of contrast formula focusing method and mobile terminals, cam lens can be made quickly to look for
To best focusing position, so as to improve the focusing speed of contrast formula focusing.It is described in detail separately below.
Referring to Fig. 1, Fig. 1 is a kind of flow diagram of contrast formula focusing method disclosed by the embodiments of the present invention.Wherein,
Method shown in FIG. 1 can be applied to smart mobile phone (such as Android phone, iOS mobile phones), tablet computer, palm PC with
And mobile internet device (Mobile Internet Devices, MID), personal digital assistant (Personal Digital
Assistant, PDA), media player, smart television, smartwatch, intelligent glasses, the mobile terminals such as Intelligent bracelet.Such as Fig. 1
Shown, which may comprise steps of：
S101, when receive for target subject focusing instruction when, acquisition for mobile terminal be directed to the target subject
Two image data waveforms between phase difference value.
In the embodiment of the present invention, the camera of mobile terminal includes imaging sensor, can by imaging sensor come
Image is acquired, which can be linear transducer.Due to phase focusing speed, mobile terminal leads to
Often phase focusing mode can be used to focus.In phase focus process, mobile terminal can be obtained by imaging sensor
Two images so as to obtain the image data waveform of the two images, and calculate the phase between the two image data waveforms
Potential difference value carries out phase focusing according to phase difference value.
Therefore, after the region where user in preview image clicks or touch target subject, the mobile terminal
The focusing instruction for the target subject will be received, preferred phase focusing mode is focused.Specifically, mobile terminal
Can two image data waveforms for the target subject be obtained, and obtain the two image datas by imaging sensor
Phase difference value between waveform.
As a kind of feasible embodiment, acquisition for mobile terminal is directed to two image data waveforms of the target subject
Between the concrete mode of phase difference value may comprise steps of：
Step 11) obtains the first image for the target subject by the left pixel of imaging sensor in camera
Image data, and pass through the imaging sensor right pixel obtain the second image image data.
In the specific implementation, in phase focusing technology, the pixel of imaging sensor includes left pixel and right pixel,
When being focused, two images that left and right pixel obtains preview screen respectively are first passed through.
Therefore, after receiving for the focusing instruction of the target subject, which will pass through camera
The left pixel of middle imaging sensor obtains the first image for the target subject, so as to obtain the picture number of the first image
According to；And pass through the right pixel of imaging sensor or the second image for the target subject in camera, so as to obtain
The image data of second image.Wherein, image data can include but is not limited to rgb value, grayscale value, gray value etc..
Step 12) generates the first image data waveform according to the image data of first image, and according to the second image
Image data generates the second image data waveform.
In the specific implementation, after image data of the acquisition for mobile terminal to the first image, it can be by the institute of first image
There is image data to generate the first image data waveform；And after image data of the acquisition for mobile terminal to the second image, it can incite somebody to action
All image datas of second image generate the second image data waveform.
For example, after mobile terminal gets the rgb value of the first image by left pixel, can according to this first
All rgb values of image generate the first image data waveform；When mobile terminal gets by right pixel the RGB of the second image
After value, the second image data waveform can be generated according to all rgb values of second image.Due to waveform, there are wave crests and wave
Paddy, therefore, the mobile terminal can calculate the first image data waveform by the phase between the wave crest or trough of waveform
With the phase difference value between the second image data waveform.
Step 13) calculates the phase difference value between the first image data waveform and the second image data waveform.
In the specific implementation, when mobile terminal generate respectively the first image data waveform and the second image data waveform it
Afterwards, which will calculate the phase difference value between two image data waveforms.Under normal conditions, only when two images
Phase difference between data waveform be zero when, just represent the preview image obtained as most clearly image, and if two figures
As there are during phase difference between data waveform, it is necessary to obtain most clearly preview image by the form of focusing.In phase pair
Under burnt pattern, the focusing position of camera can be determined by the phase difference value calculated, so as to realize rapid focus.
Further, the phase difference value calculated between the first image data waveform and the second image data waveform also may be used
To be interpreted as：The distance between first image and the second image are detected by linear transducer, the distance it can be appreciated that
Phase difference between two image data waveforms.
S102, the mobile terminal judge whether the phase difference value meets the entry condition of contrast formula focal modes, if so, holding
Row step S103；If it is not, terminate this flow.
In the embodiment of the present invention, mobile terminal is when using phase focusing technology, since phase focusing is also passive type pair
Burnt mode is to reflect into camera lens by light, is then delivered to corresponding component and is identified up, and how determines Focusing module
Work.So, when light is weaker or during insufficient light, focusing speed and performance can be decreased obviously, it is also possible to which appearance can not
The situation of focusing.
That is, if light is weaker in external environment, the absolute value for the phase difference value that acquisition for mobile terminal arrives is smaller,
May result in cannot start phase focal modes, and in order to realize focusing faster, which will use contrast
Formula is focused.
Therefore, after acquisition for mobile terminal to the phase difference value between two image data waveforms, the mobile terminal is just
It can judge whether the phase difference value meets the entry condition of contrast formula focal modes, it is understood that be：The mobile terminal can be sentenced
Break the phase difference value whether can phase-triggered focal modes entry condition.
Further, when mobile terminal judges that the phase difference value meets the entry condition of contrast formula focal modes,
Indicate that the phase difference value is unable to the startup of phase-triggered focal modes, therefore, which will start the focusing of contrast formula
Pattern；And when mobile terminal judges that the phase difference value is unsatisfactory for the entry condition of contrast formula focal modes, also indicate that this
The startup of phase difference value energy phase-triggered focal modes, then the mobile terminal will continue to using phase focal modes to the mesh
Mark subject is focused.
As a kind of feasible embodiment, which judges whether the phase difference value meets contrast formula focal modes
The concrete mode of entry condition may comprise steps of：
Step 21) determines the absolute value of the phase difference value.
In the specific implementation, the phase difference value between two image data waveforms may be positive number, it is also possible to for negative, phase
The positive negativity of difference can represent that the camera lens of the camera of mobile terminal is moved to the positive negative direction of focusing position respectively.Therefore,
After acquisition for mobile terminal to the phase difference value between two image data waveforms for target subject, the mobile terminal
The absolute value of the phase difference value will be calculated.
Step 22) judges whether the absolute value is less than predetermined threshold value.
In the specific implementation, when the absolute value for determining the phase difference value, the mobile terminal will by the absolute value come
Judgement is to start phase focal modes or start contrast formula focal modes.Under normal conditions, it is to need to start phase focal modes
The absolute value of phase difference value is wanted to be more than what some threshold value could trigger, if less than the threshold value, is focused in order to realize, generally
Contrast formula focal modes can be started.
That is, the predetermined threshold value is the line of demarcation between contrast formula focal modes and phase focal modes.This is default
The size of threshold value can depend on the circumstances, you can to determine that the embodiment of the present invention is not done according to the focus performance of module of phase
It limits.Therefore, after the absolute value of the phase difference value is determined, it is pre- which will judge whether the absolute value is less than
If threshold value.If it is lower, determine that the phase difference value meets the entry condition of contrast formula focal modes；And if it does, with regard to table
The bright phase difference value meets the entry condition of phase focal modes, and therefore, which will start phase focal modes pair
The target subject is focused.
Step 23) determines that the phase difference value meets contrast formula focusing mould when judging that the absolute value is less than predetermined threshold value
The entry condition of formula.
In the specific implementation, when mobile terminal judges that the absolute value is less than predetermined threshold value, the phase difference value is indicated that not
Energy phase-triggered focal modes, so as to trigger contrast formula focal modes, therefore, the mobile terminal it is determined that the phase difference
Value meets the entry condition of contrast formula focal modes.
For example, the phase difference between two image data waveforms for target subject are got is -30 degree
When, phase difference value be -30, the mobile terminal so as to determine the absolute value of the phase difference value be 30.Work as predetermined threshold value
When being 20, which will judge that the absolute value is more than predetermined threshold value, be unsatisfactory for instead so that it is determined that going out the phase difference value
The entry condition of differential focal modes；And if when the predetermined threshold value is 35, then the absolute value is less than predetermined threshold value, because
This, which is assured that out that the phase difference value meets the entry condition of contrast formula focal modes.
Optionally, due to the absolute value of phase difference value it is smaller when, reliability is also smaller, therefore, is judging the phase
After difference meets the entry condition of contrast formula focal modes, in order to realize rapid focus under contrast formula focal modes,
The absolute value of the phase difference value had better not be less than target predetermined threshold value, wherein, which is less than predetermined threshold value.
That is, in order to accurately determine the focusing number of the focusing position under contrast formula focal modes according to phase difference value
According to the absolute value of the phase difference value is preferably between target predetermined threshold value and predetermined threshold value, such as no more than 25 and not less than 10.
S103, the mobile terminal start contrast formula focal modes, and according to the phase difference under the contrast formula focal modes
Value determines the focus data of the focusing position of camera.
In the embodiment of the present invention, focus data can be moved to the shifting of the camera focusing position including the camera lens of camera
Dynamic direction can also include mobile distance etc., and the embodiment of the present invention does not limit.
Under normal conditions, after contrast formula focal modes are started, the mobile terminal can control the camera lens of camera according to
Preset track movement, if not finding focusing position as first moved forward, then moves backward, again so as on preset track
Find focusing position.
And in the embodiment of the present invention, after entry condition that the phase difference value meets contrast formula focal modes is judged,
The mobile terminal will start the focusing of contrast formula, and then under contrast formula focal modes, camera shooting is determined according to the phase difference value
The focus data of the focusing position of head.
Wherein, due to phase difference value, there are positive numbers and negative, if phase difference value is positive number, illustrate a certain image data wave
Shape another image data waveform positive direction, and if phase difference value be negative, then just illustrate a certain image data waveform
In the negative direction of another image data waveform, accordingly, it is possible to determine the camera pair according to the positive negativity of the phase difference value
The direction of burnt position is forward or backward.Further, which can also determine camera by phase difference value
Camera lens movement general distance, more can find focusing position by fast accurate in this way, focus so as to fulfill contrast formula.
As a kind of feasible embodiment, the mobile terminal is true according to the phase difference value under the contrast formula focal modes
Determining the concrete mode of the focus data of the focusing position of camera can be：
When the phase difference value is more than preset phase difference, the movement for the focusing position that first direction is the camera is determined
Direction, wherein, the first direction for the camera camera lens towards the direction of the target subject；
When the phase difference value is less than the preset phase difference, the shifting for the focusing position that second direction is the camera is determined
Dynamic direction, wherein, the second direction be with the first party in the opposite direction.
In the specific implementation, when the moving direction of camera lens of the focus data including camera to focusing position, this is default
Phase difference value is 0, and therefore, which can determine its moving direction by judging the positive negativity of the phase difference value.
That is, when the phase difference value is more than 0 and is positive number, which is assured that first direction to be somebody's turn to do
The moving direction of the focusing position of camera.Wherein, first direction represent be the camera camera lens towards the target shoot
The camera lens outwardly direction in the direction of object, i.e. camera.And when the phase difference value is less than 0 and is negative, the mobile terminal is just
It can determine the moving direction for the focusing position that second direction is the camera.Wherein, the second direction and first direction on the contrary,
What i.e. the second direction represented is the camera lens of the camera backwards to the direction of the target subject.
As an example it is assumed that the phase difference value of acquisition for mobile terminal is -18, predetermined threshold value 20, then may determine that
The absolute value 18 of the phase difference value is less than predetermined threshold value 20.Therefore, the mobile terminal is it may determine that go out phase difference value satisfaction
The entry condition of contrast formula focal modes, so as to start contrast formula focal modes.It is negative due to phase difference value -18, then
The mobile terminal be assured that out the focusing position of camera moving direction be backwards to target subject direction, i.e., to
Afterwards.And if the phase difference value of acquisition for mobile terminal is 16, then be assured that the moving direction of the focusing position of camera
For towards the direction of target subject, i.e., forward.
S104, the mobile terminal control the camera lens of the camera to be moved to the focusing position, and tie according to the focus data

Data control the camera lens of the camera to be moved to the focusing position.Specifically it can be understood as：When focus data is moving direction,
After the moving direction for the focusing position for determining camera, which will control the camera lens of the camera towards the shifting
Dynamic direction movement, so as to be quickly found out focusing position；Further, when focus data further includes displacement distance, the shifting
Dynamic terminal is assured that out the approximate location of the focusing position of the camera, i.e., is probably needed on the moving direction determined
Mobile distance, then the mobile terminal will control the camera lens of the camera to be moved towards the position, to be quickly found out focusing position
It puts.
As an example it is assumed that predetermined threshold value is 30, and when user needs to focus to the kitten in preview screen, user's meeting
The kitten is clicked on the screen, and then mobile terminal can obtain two images for kitten, and by the rgb value of the two images
Two image data waveforms are generated, it is 22 then to calculate the phase difference value between the two image data waveforms.Therefore, the shifting
Dynamic terminal is it may determine that go out the entry condition that the phase difference value meets contrast formula focal modes, so as to start contrast formula pair
Burnt pattern, and determined by the phase difference value camera focusing position moving direction for forward.Therefore, the mobile terminal is just
The camera lens of the camera can be controlled to move forward to be quickly found out focusing position, so as to which the focusing to kitten is rapidly completed.
As it can be seen that in the described methods of Fig. 1, when receiving the focusing instruction for target subject, mobile terminal

The entry condition of sufficient contrast formula focal modes, if it is satisfied, just starting contrast formula focal modes, and under contrast formula focal modes
The focus data of the focusing position of camera is determined according to the phase difference value, the camera is finally controlled according to the focus data
Camera lens is moved to the focusing position.Through the embodiment of the present invention, when starting contrast formula focal modes, the phase of acquisition can be passed through
Potential difference value determines the direction of the focusing position of camera, and the camera lens for then directly controlling the camera is moved to the direction, from
And focusing position can be quickly found out, the focusing speed of formula of intensifying focusing promotes user experience.
