Based on above-mentioned mobile terminal hardware configuration and communications network system, each embodiment of the method for the present invention is proposed.
With reference to Fig. 3, first embodiment of the invention provides a kind of flexible screen control method, the flexible screen control method packet
It includes：
Step S10 obtains selected shooting when receiving the control instruction of track up pattern unlatching by image recognition
Clarification of objective information, and obtain corresponding target image；
Specifically, when shooting, user can open the control instruction of track up pattern by transmission, to open tracking
Pattern.After tracing mode is opened, user is then obtained by image recognition technology and is used by the selected target in screen, mobile terminal
The selected target image in family.
Step S20 determines position coordinates of the target image in screen, and according to the position coordinates and screen of target image
In preset reference region relative distance, judge whether to flexible screen carry out shape control；
Specifically, after the target image for obtaining track up, by position of the target image in screen with the shape of coordinate
Formula is quantified, and then whether is located at preset reference region according to the coordinate position of target image, judges whether to control flexible screen
Deformation.By quantization, position that can be more accurately to target image in screen judges, and more preferably to control
Flexible screen deformation opportunity and scene.
Step S30, it is true according to the position coordinates of target image when judgement judgement needs to carry out shape control to flexible screen
Shape variable element, and carries out corresponding shape control to flexible screen.
Specifically, when judgement needs to carry out shape control to flexible screen, according to the coordinate of target image, it may be determined that mesh
Logo image deviates the direction in preset reference region, the direction of flexible screen deformation is determined with this, and detect and move according to sensor
The current stress area of terminal, according to stress area and deformation direction, control flexible screen carries out deformation.
Camera function is that the most commonly used one of function is used in mobile terminal, and can record user by camera shooting wants note
The slice of life of record, so as to be recalled at any time, to obtain more joys of life.But user is to carry out camera shooting dynamic
When the object of state, needs to carry out track up to object, can preferably record slice of life.And partial dynamic object due to
It is kept in motion, and without the apparent characteristics of motion, therefore user can not effectively prejudge the movement locus of object, so
May result in user can not capture object in time, eventually cause user and occur wanting the target of shooting when shooting and leave and take the photograph
As the case where head coverage.Such as user, when shooting the image that child plays, child it is possible that run suddenly
Behavior, and user it is reflect in time in the case of, then the case where running out of except pick-up lens it is easy to appear child,
To influence the final effect of user's shooting.Such that the usage experience of user is affected.
The problem of being lost for photographic subjects, the mobile terminal of traditional type when shooting for losing photographic subjects not
Good solution, and the present invention by the mobile terminal of flexible screen material can Deformation Features, realize a kind of tracking and clap
Take the photograph method.After user opens track up pattern, the shooting second is chosen first, and mobile terminal is known by image recognition technology etc.
Do not go out the characteristic information of target image, target image is then positioned by characteristic information, such as when target image is people, then it can be with
The general image of target is identified by identifying the features such as eyes, nose, face, ear.By target image in screen
Coordinate, which can know whether to need to control flexible screen, carries out deformation, when judging target image in screen by profile information
Preset reference region when, then be not necessarily to control flexible screen carry out deformation, and when judgement targeted graphical position be located in screen
When except preset reference region, then control flexible screen deformation is demonstrated the need for so that shooting angle changes, to ensure shooting
The image of target maintains in coverage.
The mode that deforms upon of mobile terminal control flexible screen, can by the mechanical device installed in mobile terminal with it is right
Module is answered to realize, mobile terminal can be realized with corresponding control method to flexible screen deformation degree and direction by mechanical device
Control, mobile terminal can also be met using other, mode of flexible screen demand for control is realized.Due to flexible screen
Deformation can change the shooting angle of camera, therefore can be reached to a certain degree to shooting mesh by controlling flexible screen deformation
There is the case where photographic subjects flee from coverage so as to improve user when using camera function in target tracking effect.User
After opening track up function, mobile terminal can continue to obtain coordinate of the target image in screen, and in target image
Coordinate when being detached from preset preset reference region in screen, according to the coordinate shift direction of target image, control flexible screen into
Corresponding deformation go to adjust shooting angle, so as to adjust target image into preset reference region.Such as in movement
Under the horizontal state of terminal, detect that the coordinate of target image is located at except preset reference region.According to the direction of coordinate position, control
The deformation direction of flexible screen processed is finally reached the purpose for the coverage that photographic subjects are maintained to camera.
When controlling mobile terminal deformation, it is also necessary to detect the force part of mobile terminal flexible screen, that is, hold or solid
Fixed point.Such as mobile terminal is divided into upper end, centre, the position of lower end three, camera is located at upper end, when the hand-held movement of user
When lower end, the shooting angle of camera can be changed by middle section deformation.And when in user's hand-held mobile terminal
Between part when, the deformation of lower end can not then change shooting angle, then the upper part that must change mobile terminal can
Realize the purpose for changing shooting angle.Therefore before controlling flexible screen deformation, it is thus necessary to determine that the stress of mobile terminal flexible screen
Position, to add effective mode to carry out shape control.The control of flexible screen can be by adding the mechanical parts such as foot chain, and controls
Mechanical part processed realizes the deformation of control flexible screen, can also be realized by other effective control modes.
Flexible screen image pickup method through the invention, user can when being shot to dynamic object using camera function,
Obtain higher shooting quality.Photographic subjects are encountered in the state of fast moving, and mobile terminal can be by controlling flexible screen
Corresponding deformation is carried out, can track up be carried out to photographic subjects to a certain extent, to allow user to have enough time
The action of target user is reacted (mobile terminal by hardware limitations such as flexible screen deformation limits, cannot it is unconfined into
Line trace), and (such as adjustment shooting direction etc.) can be coped in time.Therefore it is possible to prevente effectively from user is in shooting dynamic
When object, there is the case where object fast moves caused disengaging coverage so that user can get better bat
Effect is taken the photograph, the usage experience of user is increased.
Further, step S20 determines that the step of position coordinates of the target image in screen includes：
The center of target image is calculated according to mathematical relationship by step S21；
Step S22 obtains coordinate of the center in screen, and as the position coordinates of target image.
Specifically, when obtaining the position of target image, the finger of user's selection is got by image recognition technology first
The photographic subjects in region are determined, then according to geometry far from the central point that can get target image, then according to central point
Position coordinates in screen judge target image the location of in screen.
In track up pattern, an important problem is exactly how the position of target determines, passes through screen in the present invention
Curtain shows position of the target image in screen in the form of coordinate system, with position coordinates.The screen shape of mobile terminal is general
Close to rectangle, and then accurately the position of target image can be stated by the form of coordinate.And target image
Due to being irregular in most cases, pass through the position coordinates using the coordinate of central point as target image.And
The central point of target image can be counted according to the computational methods (central points of irregular geometric figures) of central point in geometrical relationship
Obtain, other than using central point calculating position, can also according to the difference of actual conditions, using the forms such as boundary coordinate into
Row calculates.The position of target image can be quantified by the form of coordinate, and facilitates subsequent calculating.
Further, step S20 according to the preset reference region in the position coordinates and screen of target image it is opposite away from
From, judge whether to flexible screen carry out shape control further include：
Step S23 determines the range in the preset reference region in screen according to target image；
Step S24 judges whether to carry out deformation to flexible screen according to the position relationship of target image and preset reference region
Control.
Specifically, the range in the preset reference region in screen is determined according to the size of target image so that preset reference
The range in region can match with target image.After the range for determining preset reference region, according to target image and preset
The position relationship of reference zone, for example, target image in preset reference region, on the left of preset reference region, the positions such as right side
Corresponding deformation occurs for relationship, control flexible screen.
After target image is determined, then the range that preset reference region is determined according to target image, target figure are needed
The volume of picture is bigger, and (volume herein is not necessarily referring to the actual volume size of photographic subjects, but target figure displayed in the screen
As the accounting size in screen), then the range in corresponding preset reference region is smaller, so as to ensure that target image can
It is in the preset reference region of screen as far as possible so that the effect of track up is more preferable.And preset reference region is being determined
Range after, may determine that it is the flexible shape of control according to the correspondence in the position coordinates of target image and preset reference region
The direction of change and deformation.
Further, step S23 determines that the range in the preset reference region in screen includes according to target image：
Step S231 obtains target image and occupies ratio in screen, occupies ratio according to described to correspond to setting default
The range of reference zone.
Specifically, the size in preset reference region is relevant with the size of target image, and the volume of target image is bigger,
Then the range in corresponding preset reference region is smaller.
It is that the position coordinates of the central point of the target image used are counted since the present invention is in calculating position relationship
Calculate, thus target image volume (image volume, not the actual volume of object) it is bigger when, the range in preset reference region
It is corresponding then smaller, so as to ensure that target image is in screen ranges so that user can obtain preferable shooting effect.
Further, step S24 judges whether according to the position relationship in target image and preset reference region to flexible screen
Carry out shape control the step of include：
Step S241, when detecting that target image is located in the range of preset reference region, then judgement need not be to soft
Property screen carry out shape control；
Step S242 then judges to need to flexibility when detecting that target image is located at outside the range in preset reference region
Screen carries out shape control.
Specifically, when the position coordinates of target image are located in the range of preset reference region, then show target image
It is currently in the central part of screen, there is no need to control flexible screen deformation.And works as and detect that the position coordinates of target image exist
When except preset reference region, then need opposite with preset reference region to adjust target image by controlling flexible screen deformation
Position.
Judging whether that it when carrying out track up, is the coordinate by target image by controlling flexible screen deformation to need
What the position relationship in position and preset reference region judged.Pass through the position of the position coordinates and preset reference region of target image
Relationship (i.e. the position of target image be in the preset reference region or preset reference region outside), can be simple and quick sentence
It is disconnected whether to need to control flexible screen deformation so that track up can quickly obtain knot when being made to determine whether to need deformation
By, and responded.
Further, with reference to Fig. 4, step S30 is determined according to the position coordinates of target image in another embodiment of the present invention
Deformation parameter, and corresponding shape control is carried out before to flexible screen and includes：
Step S31 detects the force part of flexible screen by sensor, according to the location determination flexible screen of force part
Deformation region.
Specifically, before controlling flexible screen deformation, it is necessary first to detect flexible screen force part (such as user hold
When mobile terminal, the position grade force part of hand gripping), the position of deformation can be different according to the difference of force part.
When shooting, often hand-held or other modes fixed cellular terminal, is being imaged user, therefore mobile whole
End (can detect that the external force such as pressure may determine that the forced section of mobile terminal there are one force part by sensor
Position), and under tracing mode, the deformation position of control flexible screen deformation then (must avoid the shape of flexible screen except force part
Become and flexible screen is fixed to user cause harmful effect, can not effectively fix or loosen to causing flexible screen and the accident feelings such as fall
The generation of condition).The purpose of controlling the deformation of flexible screen simultaneously is to change the shooting angle of camera, therefore camera must be positioned at shape
Become region in, therefore deformation region needs be changed according to the difference of stress area, use so that flexible screen deformations
Position is more scientific and effective, different schematic diagram such as Fig. 5 and Fig. 6 influenced caused by deformation region of stress area.
Further, step S31 detects the force part of flexible screen by sensor, according to the location determination of force part
Include after the deformation region of flexible screen：
Step S32, root obtains coordinate vector according to the coordinate of target image, and determines deformation according to the direction of coordinate vector
Direction；
Step S33, control flexible screen carry out deformation in the deformation direction.
Specifically, when control flexible screen carries out deformation, the position coordinates of target image are expressed in the form of vectors, and it is vectorial
It is that tool is directive as vector, then deformation direction can be determined according to the vector of position coordinates, then controls flexible screen in shape
It changes direction and deforms upon.
The factors such as the origin according to coordinate system, the vector that the position coordinates of combining target image are formed can determine flexible screen
Deformation direction, such as when using screen center as coordinate origin, the direction of position coordinates is deformation direction, then in corresponding side
Corresponding deformation (including bending, the deformation such as varicose) is carried out upwards, and deformation schematic diagram such as Fig. 7 changes camera to reach
The purpose of shooting angle, the final track up effect realized to photographic subjects.
Further, step S33 control flexible screens include after the step of deformation direction carries out deformation：
Step S34 detects the deformation quantity of flexible screen, when deformation quantity is more than default deformation threshold value, stops deformation, and export
Prompt message.
Specifically, in order to ensure that the normal use of flexible screen mobile terminal, track up pattern unconfined can not be controlled
Flexible screen processed deforms upon, and when the deformation quantity of flexible screen is more than default deformation threshold value, then needs to stop deformation, and by raising one's voice
The equipment such as device, shock module export the prompt messages such as sound, vibrations to prompt user to pay attention to the deformation degree of flexible screen.
It, can be such as excessive in deformation degree with the normal use of effective guarantee user by the way that deformation threshold value flexible is arranged
When, it may cause user that can not normally obtain the display content (the too big influence display effect of deformation degree) of flexible screen, while with
The function of track shooting can not substitute user hand motion tracking completely, therefore when deformation degree is more than default deformation threshold value, lead to
While crossing output prompt message call user's attention flexible screen deformation degree, the also manual track up mesh of call user's attention
Mark.
