In step S43, when the phase difference of pairs of image is zero, determine that the camera lens of front camera focuses to object
Accurately.
The technical scheme provided by this disclosed embodiment can include the following benefits: can be directly by comparing figure in pairs
The phase difference of picture completes accurate focusing of the camera lens institute of front camera to object, without as tradition focusing mode from imaging
Obscure clearly arrive again it is fuzzy during imaging is compared repeatedly, so that the time used in focusing be greatly reduced.
In one embodiment, as shown in figure 5, method may also include step S51-S52:
In step s 51, when phase difference is not equal to zero, sensor determines focusing adjustment direction and focusing according to phase difference
Adjustment amount；
In step S52, sensor is according to focusing adjustment direction and position of the adjustment amount to the camera lens of front camera of focusing
It sets and is adjusted.
For example, the incident ray of the camera lens of front camera is divided into pairs of image by sensor；Sensor calculates
The phase difference of pairs of image；When phase difference is not zero, sensor determines that focusing adjustment direction and focusing are adjusted according to phase difference
Whole amount；And the position of the camera lens of front camera is adjusted according to focusing adjustment direction and focusing adjustment amount；When executing tune
It is whole operation it is correct when, the phase difference of the pairs of image after adjusting is zero, when the phase difference of pairs of image is zero, determine before
The camera lens for setting camera focuses accurately to object.Such scheme has abandoned the process compared repeatedly in traditional focus process, only
It only needs once to focus and primary adjustment can be completed accurately to focus.
The technical scheme provided by this disclosed embodiment can include the following benefits: when phase difference is not equal to zero,
Focusing adjustment direction and focusing adjustment amount can be determined according to phase difference, and then by focusing adjustment direction and focusing adjustment amount to the greatest extent
Head position is adjusted, thus, focusing can be completed by once focusing and once adjusting, further reduce used in focusing
Time.
Fig. 6 is a kind of flow chart of terminal control method shown according to an exemplary embodiment, as shown in fig. 6, the end
Hold control method for including the following steps S601-S610 in terminal:

In step S602, the phase difference for the image that sensor is calculated as pair；
In step S603, when phase difference is not equal to zero, sensor determines focusing adjustment direction and right according to phase difference
Burnt adjustment amount；
In step s 604, sensor is according to focusing adjustment direction and position of the adjustment amount to the camera lens of front camera of focusing
It sets and is adjusted；
In step s 605, when the phase difference of pairs of image is zero, determine the camera lens of front camera to object pair
It is burnt accurate；
In step S606, when the camera lens of front camera is accurate to object focusing, sensor obtains front camera
Focal distance；
In step S607, sensor is according to the distance between camera lens of front camera to photosensitive element and focal distance
Object is calculated at a distance from the camera lens of front camera, obtains the distance between object and terminal；
In step S608, the distance between object and terminal are sent processor by sensor；
In step S609, in communication process, when the distance between object and terminal are less than or equal to the first default threshold
When value, processor generates first control signal and is sent to screen controller, and first control signal is used for the screen of controlling terminal
Locking is closed；
In step S610, when the distance between object and terminal are greater than or equal to the second preset threshold, processor is raw
At second control signal and it is sent to screen controller, second control signal is used for the unlocking screen of controlling terminal or lights.
By taking user is conversed by mobile phone as an example, when mobile phone is close to human body, touch can be generated to mobile phone screen with human body
The distance of input presets one greater than the critical value close to threshold value as critical value, then default one is greater than the critical value
Gradually from threshold value, in communication process, mobile phone be to object people face, mobile phone built-in sensors are by the camera lens of front camera
Incident ray be divided into pairs of face image, and the phase difference to image is calculated as, when the phase difference of the pairs of image is not
When zero, sensor determines focusing adjustment direction and focusing adjustment amount according to the phase difference, and according to determining focusing adjustment direction
The position of the camera lens of front camera is adjusted with focusing adjustment amount, when the phase difference of pairs of image is zero, is determined
The camera lens of front camera to the focusing of object be accurately, the side that this phase difference by pairs of image is focused
The principle that formula is similar to animal or mankind's eyes are focused.And when focusing of the camera lens of preposition head portrait to object is accurate, mobile phone
Built-in sensitive chip obtains the focal distance A of mobile phone front camera, i.e. the distance between object and imaging.And then it is logical
Cross the distance between the photosensitive element that focal distance A is subtracted built in the camera lens to mobile phone of mobile phone front camera B, focal distance A
With the camera lens distance B of mobile phone front camera subtract each other gained difference be mobile phone front camera camera lens institute it is in one's hands to object
The distance between machine C, i.e. A-B=C.The distance between face and terminal are sent processor by sensor；If it is determined that mobile phone
When at a distance from user face for less than or equal to close to threshold value, processor generates the control of an instruction screen locking or closing
Signal is sent to screen controller, and screen controller is according to the control semaphore lock or closes screen.When user opens hands-free function
When needing operating handset when perhaps end of conversation needs to hang up when can be carried out call or in communication process, mobile phone is from user's face
Portion takes away, when mobile phone at a distance from object be greater than or equal to it is preset gradually from threshold value when, processor generate an instruction screen open
The control signal for beginning or lighting is sent to screen controller, and screen controller opens or light screen according to the control signal.
It should be noted that the distance between object and terminal can also obtain in the following way: when preposition head portrait
When camera lens is accurate to the focusing of object, photosensitive element is to camera lens distance b with parfocal plane with parfocal plane distance a
Definite value, therefore can be according to light in the incident angle of photosensitive element and the direction adjustment amount of camera lens and apart from both adjustment amounts
Obtain camera lens to parfocal plane incident angle, then by the refractive index of camera lens obtain the same point of object camera lens topmost
Topmost obtained with the lowermost distance with the incident angle and camera lens of two incident rays of the lowermost camera lens and object it
Between distance.
The technical scheme provided by this disclosed embodiment can include the following benefits: be not necessarily to mounting distance sensor
Electric signal or coupled capacitor when without calculating screen and close human body determine face between mobile phone in the case where changing
Distance, and being compared according to determining distance with preset threshold, when less than the first preset threshold, controlling terminal screen locking or
It closes, prevents user from accidentally touching screen in communication process and maloperation occurs；In addition, when being greater than the second preset threshold,
It by unlocking screen or lights, makes the user do not need to light screen manually.I.e. without mobile phone sensor, without calculating screen and people
Electric signal or coupled capacitor when body is close realize screen intelligence in the case where changing is closed and is lighted.
