Step 110, the person's handwriting control operation in response to receiving, show at least one handwriting trace, deposit in handwriting trace The first tracing point in the enclosed region for being located at Target ellipse and the second tracing point outside enclosed region.

Illustratively, person's handwriting control operation is control operation that user issues, for handwriting trace.Wherein, rail is write Mark is user under writing function, and the track being written by touch control operation, it includes multiple continuous tracing points, each tracing points A corresponding coordinate points.Coordinate points are the point in operating area coordinate system.Specifically, coordinate system is created for operating area in advance, Wherein, the specific location embodiment of the origin of coordinate system is not construed as limiting.Further, in order to guarantee that user has enough operating spaces Domain, setting operation region does not have fixed dimension in embodiment, i.e. operating area can be infinitely great.For example, operating area can be with The writing process of user infinitely expand.Wherein, specific expansion mode and direction of expansion embodiment are not construed as limiting.It can manage Solution, since the size of display screen is limited, so in display screen can only display portion operating area, and detecting user Operating area when issuing setting replacement operation in replacement display screen.The operating area replaced in display screen may include mobile behaviour Make region, zoom operations region etc..Wherein, the specific implementation embodiment for setting replacement operation is not construed as limiting, for example, detection To user's palm touching display screen, and when progress moving operation, movement routine, and then basis are determined according to the track of moving operation The operating area shown in movement routine replacement display screen.Further, the coordinate of the operating area shown in display screen is determined Range, and then determine according to coordinate range the corresponding relationship of coordinate points and pixel.Wherein, each pixel is corresponding in display screen One pixel coordinate passes through the available coordinate points of pixel coordinate range and pixel of the coordinate range and display screen of operating area The corresponding relationship of point.Typically, when obtaining touch control operation, determine the corresponding pixel of touch control operation, and according to coordinate points with The corresponding relationship of pixel determines coordinate points corresponding with pixel, and then using the coordinate value of coordinate points as corresponding tracing point Coordinate position.Meanwhile the pixel coordinate for showing tracing point being denoted as to the location of pixels of tracing point.When the operating space in display screen When domain is constant, if the location of pixels of tracing point changes, the coordinate position of tracing point, which synchronizes, to change.In embodiment, It is described so that the operating area in display screen is constant as an example.

In embodiment, setting person's handwriting control operation includes at least one in write operation, moving operation and amplifying operation Kind.Wherein, write operation refers to the operation of write-in handwriting trace, shows that at least one is new after completing write operation, in display screen The handwriting trace of increasing.Moving operation refers to the operation of mobile handwriting trace location of pixels, and in embodiment, moving operation is used for book At least one tracing point for writing track moves into the enclosed region of Target ellipse.The size referred to handwriting trace is enlarged The operation amplified expands the coordinate range of handwriting trace, wherein coordinate range is whole tracing points in handwriting trace Coordinate position set.Further, person's handwriting control operates corresponding touch control manner embodiment without limitation.For example, user selects After writing function, if interactive intelligent tablet computer detects mobile touch control operation in operating area, it is determined that receive write-in behaviour Make.For another example, after the coordinate range where detecting certain handwriting trace is selected and moves, determination receives moving operation, And the handwriting trace is moved according to the path of moving operation.

In embodiment, set interactive intelligent tablet computer can graphing as ellipse.The specific drafting means of ellipse are implemented Example is without limitation.Further, Target ellipse is the ellipse currently having shown that, it is understood that is that Target ellipse is to use Family is the person's handwriting frame of handwriting trace setting, is used to integrate handwriting trace, i.e., handwriting trace is placed in target as a whole Elliptical inside.Wherein, the inside of Target ellipse refers to inside enclosed region that Target ellipse surrounds, correspondingly, Target ellipse Outside refer to other regions in addition to enclosed region.It is understood that Target ellipse is only a kind of optional way, implement In example, the figure for integrating handwriting trace can also be the convex polygons such as circle and matrix, square, diamond shape, triangle.

Typically, in embodiment, after setting response person's handwriting control operation, display track relevant to person's handwriting control operation, And when at least one tracing point is located in the enclosed region that ellipse has been displayed in some in track, corresponding ellipse is denoted as Target ellipse.Further, whole pixels of Target ellipse enclosed region are traversed, with determine in enclosed region whether there is also Other tracks.Other tracks if it exists, then it is synchronous to obtain other tracks.Later, it determines relevant to person's handwriting control operation In track and other tracks, if there is the tracing point in Target ellipse enclosed region and the rail outside enclosed region Mark point.If it exists, then person's handwriting is controlled into the relevant track of operation and other tracks is determined as handwriting trace.Wherein, tracing point exists Refer to the location of pixels of tracing point in enclosed region in the pixel region of Target ellipse, pixel region refers to that Target ellipse surrounds The corresponding pixel coordinate set of enclosed region.Further, setting will be located in Target ellipse enclosed region in handwriting trace Tracing point be denoted as the first tracing point, by be located at enclosed region outside tracing point be denoted as the second tracing point.That is handwriting trace only portion Divide and is shown in Target ellipse.In general, the second tracing point being located at outside enclosed region is track relevant to person's handwriting control operation On tracing point.Since handwriting trace is shown in display screen, in embodiment, the determining, position using location of pixels as position Set the relevant parameter of statement and calculating, it is to be understood that in practical application, can also join coordinate position as correlation Number, for example, determining tracing point whether in enclosed region by coordinate position.

For example, when person's handwriting control operation is write operation, according to the track of write operation display write-in.Later, confirmation is write It is located in the enclosed region that ellipse has been displayed in some in the track entered with the presence or absence of at least one tracing point, and if it exists, then will Ellipse, which has been displayed, is determined as Target ellipse accordingly.Meanwhile each pixel in Target ellipse enclosed region is traversed, if confirmation The inside of Target ellipse is in addition to the track of write-in, and there is also other tracks, then obtains other tracks.Later, confirm write-in In track and other tracks, if be located in the enclosed region of Target ellipse there are at least one first tracing point exist simultaneously to Few second tracing point is located at outside the elliptical enclosed region of same target.If it exists, then by the track of write-in and other tracks It is determined as handwriting trace.It is understood that if each tracing point is respectively positioned on the enclosed region of some ellipse in the track of write-in It is interior, then without carrying out any operation to the ellipse.

For another example, when person's handwriting control operation is moving operation, track and mobile road to be moved are determined according to moving operation Diameter, and according to movement routine motion track.After track is mobile, it whether there is at least one track in the track after confirmation is mobile Point is in the enclosed region that ellipse has been displayed in some, and if it exists, then ellipse having been displayed accordingly, to be determined as target ellipse Circle.Meanwhile each pixel in Target ellipse enclosed region is traversed, if except mobile rail in the enclosed region of confirmation Target ellipse Outside mark, there is also other tracks, then obtain other tracks.Later, confirming whether there is in mobile track and other tracks At least one first tracing point, which is located in the enclosed region of Target ellipse, exists simultaneously at least one second tracing point positioned at identical Outside the enclosed region of Target ellipse.If it exists, then mobile track and other tracks are determined as handwriting trace.It is understood that Be, if whole tracing points are respectively positioned in enclosed region of some ellipse in the track after mobile, without to the ellipse into Any operation of row.

Also such as, when person's handwriting control operation is is enlarged, track and amplification ratio to be amplified are determined according to being enlarged Example, and then amplified track is shown according to magnification ratio.Later, confirm in the track of amplification with the presence or absence of at least one track Point is in the enclosed region that ellipse has been displayed in some, and if it exists, then ellipse having been displayed accordingly, to be determined as target ellipse Circle.Meanwhile each pixel inside Target ellipse enclosed region is traversed, if except amplification in the enclosed region of confirmation Target ellipse Outside track, there is also other tracks, then obtain other tracks.Later, confirm in the track and other tracks of amplification, if deposit At least one second tracing point is existed simultaneously in the enclosed region that at least one first tracing point is located at Target ellipse is located at phase Outside with the enclosed region of Target ellipse.If it exists, then the track of amplification is determined as handwriting trace.It is understood that if putting Whole tracing points of big track are respectively positioned in the enclosed region of some ellipse, then without carrying out any operation to ellipse.

It should be noted that track is operated or is calculated for the ease of processor, usually by rail in writing process Mark is placed in corresponding element box and is shown.In general, element box is it is also assumed that be the minimum circumscribed rectangle of track, and member The boundary of plain box hides display.Further, due to a writing process, it is possible to create a plurality of track, if every track is corresponding One element box, will increase the burden of processor.Therefore, each track generated of writing can be set as to share an element Box.Wherein, after the completion of a track input, if receiving writing behaviour again in setting time interval and setting pixel distance Make, then the track being newly written and former track is considered the track obtained with a writing process, and place in identity element box. It is subsequent, if certain track is deleted or moved to remote position (by with preset distance threshold ratio in element box Compared with), it is determined that track is reduced in element box, and according to the size of residual track more new element box.If increasing certain in element box The track or increase certain track being moved in element box that item is newly written, then can be with the size of synchronized update element box.Or Person can also place the track for the condition that meets in identity element box in conjunction with actual demand.For example, by a certain Target ellipse pair The handwriting trace answered is placed in identity element box.At this point, only needing comparison element box when determining Target ellipse and handwriting trace The location of pixels of location of pixels and Target ellipse.

Step 120, the dimension data for adjusting Target ellipse, so that whole tracing points of handwriting trace are located at target after adjustment In elliptical enclosed region.

Illustratively, the dimension data of Target ellipse refers to location of pixels of the side of Target ellipse in display screen.Pass through Dimension data can determine the central point location of pixels of Target ellipse, the length in pixels of major semiaxis, the length in pixels of semi-minor axis with And length shaft length ratio.Wherein, length in pixels ratio of the length shaft length than referring to major semiaxis and semi-minor axis.It is understood that When determining above-mentioned parameter, location of pixels can be replaced with coordinate position.

Specifically, adjusting the dimension data of Target ellipse according to the location of pixels of handwriting trace.Wherein, adjustment target is ellipse Round dimension data is realized by mobile Target ellipse and/or the elliptical mode of amplification target.Mobile Target ellipse, which refers to, not to be changed Become the length in pixels of the major semiaxis of Target ellipse and the length in pixels of semi-minor axis, only changes the central point pixel position of Target ellipse It sets, to realize the dimension data of adjustment Target ellipse.Amplification target ellipse refers to the central point pixel position for not changing Target ellipse It sets, only changes the major semiaxis of Target ellipse and/or the length in pixels of semi-minor axis.In embodiment, when setting amplification target ellipse, mesh Elliptical length shaft length is marked than constant, i.e., the Target ellipse before amplified Target ellipse and amplification is similar fitgures.

Optionally, when adjusting the dimension data of Target ellipse, firstly, whole tracing points of handwriting trace are obtained, later, It include the minimum ellipse figure of corresponding tracing point, the central point and Target ellipse of each minimum ellipse figure based on each track point-rendering Central point be overlapped.In each minimum ellipse figure of drafting, the maximum minimum ellipse figure of area is selected, and the minimum is ellipse Dimension data of the dimension data of circle diagram shape as Target ellipse after adjustment.Either, in each minimum ellipse figure of drafting, The ratio of the length in pixels of the semi-minor axis of the length in pixels and Target ellipse of semi-minor axis in each minimum ellipse figure is calculated, and is selected The maximum minimum ellipse figure of ratio, using the dimension data of the minimum ellipse figure as the size number of Target ellipse after adjustment According to, or using maximum ratio as the amplification ratio of Target ellipse.

It is also optional, when adjusting the dimension data of Target ellipse, firstly, the minimum circumscribed rectangle of confirmation handwriting trace, Later, the minimum ellipse comprising the minimum circumscribed rectangle is drawn, and the dimension data of minimum ellipse is ellipse as target after adjustment Round dimension data.Either, confirm the minimum circumscribed rectangle of handwriting trace, later, obtain the center of the minimum circumscribed rectangle Point, and mobile Target ellipse, the central point of Target ellipse is overlapped with the central point of minimum circumscribed rectangle.Later, traversal is write Whole tracing points of track are confirmed whether that there is also the second tracing points being located at outside current goal ellipse enclosed region, and if it exists, Whole tracing points of handwriting trace are then obtained, later, are based on the corresponding minimum ellipse figure of each track point-rendering, each minimum ellipse The central point of figure is overlapped with the central point of Target ellipse.In each minimum ellipse figure of drafting, select area maximum most Small ellipse figure, and using the dimension data of the minimum ellipse figure as the dimension data of Target ellipse after adjustment.Either, exist In each minimum ellipse figure drawn, the length in pixels of semi-minor axis and the semi-minor axis of Target ellipse in each minimum ellipse figure are calculated Length in pixels ratio, and select the maximum minimum ellipse figure of ratio, using the dimension data of the minimum ellipse figure as The dimension data of Target ellipse after adjustment, or using maximum ratio as the amplification ratio of Target ellipse.

Optionally, after receiving person's handwriting control operation every time, can be confirmed whether to need to adjust the size number of Target ellipse According to, and when needed, the dimension data of Target ellipse is adjusted, so that Target ellipse includes whole tracks of handwriting trace always Point.Wherein, it is confirmed whether that the technological means for needing to adjust the dimension data of Target ellipse can be determining person's handwriting control operation It is located at outside the enclosed region of Target ellipse in relative trajectory with the presence or absence of at least one tracing point.

It is above-mentioned, by the person's handwriting control operation in response to receiving, show at least one handwriting trace, wherein write rail First tracing point of the mark comprising being located in Target ellipse enclosed region and the second tracing point outside Target ellipse enclosed region, Later, the dimension data for the Target ellipse having been displayed is adjusted, so that target is ellipse after whole tracing points of handwriting trace are located at adjustment Technological means in round enclosed region.Solve the technical problem low with the integration efficiency of ellipse for handwriting trace.When When handwriting trace part in ellipse exceeds ellipse, realizes ellipse and handwriting trace synchronous self-adapting is followed to amplify, mention The usage experience of user has been risen, and ensure that the rational deployment and aesthetics of display content.

Fig. 2 is a kind of flow chart of the oval processing method based on handwriting trace provided by Embodiment 2 of the present invention.This reality Applying example is to be embodied on the basis of the above embodiments.Specifically, with reference to Fig. 2, the oval processing side based on handwriting trace Method includes:

Step 201 is operated in response to the Graph Control received, and displaying target is oval.

In embodiment, only for showing ellipse in interactive intelligent tablet computer.Graph Control operation refers to the elliptical behaviour of control Make.Its specifically can be drafting oval, the elliptical major semiaxis length in pixels of adjustment, the elliptical semi-minor axis length in pixels of adjustment and At least one operation such as mobile ellipse.It is understood that Graph Control, which operates, can be directed to arbitrary ellipse, in embodiment, it is It is easy to understand, setting Graph Control operation is directed to Target ellipse, i.e., deposits in the relative trajectory that subsequent person's handwriting control operation generates In at least one tracing point in the enclosed region of the Target ellipse.

Further, the specific implementation embodiment of Graph Control operation is not construed as limiting.For example, detecting oval template After being transferred by user, determines that operating area is inscribed and receive the drag-and-drop operation based on elliptical modes plate, and operated according to drag-and-drop operation Ellipse is shown in region.For another example, if detecting, 1 points on elliptical side receive touch control operation, move according to touch-control Dynamic rail mark determines elliptical scaled size, and zooms in and out to ellipse.If detecting, any point on elliptical side receives touching Control operation, then according to touch-control motion track, determine elliptical shift position, and move to ellipse according to the shift position. In general, showing the Target ellipse operated according to Graph Control in display screen after response pattern control operation.

Step 202, the first nodal point for determining Target ellipse and the first length shaft length ratio.

Illustratively, when receiving Graph Control operation displaying target ellipse, the correlation for determining and recording Target ellipse is synchronized Data.Wherein, related data can be dimension data, first nodal point, the first length shaft length than, major semiaxis length in pixels And at least one of length in pixels of semi-minor axis etc..In embodiment, using related data as first nodal point and the first length Shaft length is than carrying out exemplary description.

Specifically, the central point of Target ellipse is denoted as first nodal point.Wherein, the method for determination embodiment of first nodal point Without limitation.For example, the long axis and short axle of Target ellipse are drawn according to the location of pixels where the side of Target ellipse, it later, will The crosspoint of long axis and short axle is denoted as the first nodal point of Target ellipse, and records the location of pixels of first nodal point.

Further, the length shaft length ratio of Target ellipse is denoted as the first length shaft length ratio.Wherein, the first length axial length Spend the method for determination embodiment of ratio without limitation.For example, drawing Target ellipse according to the location of pixels where the side of Target ellipse Long axis and short axle determine the length in pixels of long axis and the length in pixels of short axle later, and using the ratio of two length in pixels as First length shaft length ratio.

Record first nodal point and the benefit of the first length shaft length ratio are when being convenient for subsequent adjustment Target ellipse to size The calculating of data.

Step 203, the person's handwriting control operation in response to receiving, show track to be selected.

In embodiment, person's handwriting control operation is by write operation, moving operation or for being enlarged.Wherein, person's handwriting controls When operation is moving operation, after being responded according to moving operation, there is newly-increased track inside Target ellipse.

Further, after response person's handwriting control operation, display track relevant to person's handwriting control operation, and it is denoted as rail to be selected Mark.For example, at least one track being newly written is denoted as track to be selected when write operation；When amplifying operation, will be amplified to A few track is denoted as track to be selected；When moving operation, track to be selected will be denoted as by mobile track.

Step 204 judges whether to be matched to Target ellipse, in the enclosed region of Target ellipse at least comprising track to be selected One tracing point.If confirmation is matched to Target ellipse, step 205, otherwise, end operation are executed.

Specifically, traversing and all oval, the pixel region at each oval place of confirmation having been displayed after showing track to be selected. Later, according to the location of pixels of each tracing point in elliptical pixel region and track to be selected, it is determined whether exist comprising rail to be selected The ellipse of at least one tracing point of mark, and if it exists, the ellipse is then determined as Target ellipse.If it does not exist, then illustrate rail to be selected Mark does not have corresponding Target ellipse, and then terminates this operation.In general, track to be selected only corresponds to a Target ellipse.It needs It is noted that the whole ellipses having been displayed can refer to the whole in all oval or display screens in operating area It is oval.In embodiment, by taking all ellipses in display screen as an example, it is described.Certainly, if the whole ellipses having been displayed refer to operation When whole in region is oval, it is thus necessary to determine that each elliptical coordinates regional, later, root is according to elliptical coordinates regional and rail to be selected The coordinate position of each tracing point in mark, it is determined whether there is the ellipse comprising at least one tracing point of track to be selected.

It is understood that interactive intelligent tablet computer distinguishes oval and track mode embodiment without limitation.Such as track There is different marks with ellipse, interactive intelligent tablet computer determines that element is track or ellipse by identifying.

There is at least one rail in step 205, the whole tracks for obtaining Target ellipse, any bar track in whole tracks Mark point is located in the enclosed region of Target ellipse.

Specifically, whole pixels in Target ellipse are traversed after determining Target ellipse, to filter out display tracing point Pixel.In general, setting the pixel and blank or display background that the pixel inside Target ellipse includes display tracing point Pixel, can be distinguished by the pixel value of each pixel.Later, the rail in Target ellipse where each tracing point is determined Mark.Wherein, it is made of due to every track multiple continuous tracing points, it need to only find the corresponding whole of each tracing point Continuous path point, can confirm the track where each tracing point, and then obtain whole tracks of Target ellipse.

Step 206 judges in whole tracks with the presence or absence of the tracing point being located at outside enclosed region.If confirming in whole tracks In the presence of the tracing point being located at outside enclosed region, 207, otherwise, end operation are thened follow the steps.

Specifically, after determining whole tracks of Target ellipse, each tracing point of whole tracks is traversed, and by each track The location of pixels of point and the pixel region of Target ellipse are compared, and are located at outside Target ellipse enclosed region with determining whether there is Tracing point.If confirming in whole tracks there is the tracing point being located at outside Target ellipse enclosed region, illustrate Target ellipse Enclosed region does not include whole tracks, needs to be adjusted the dimension data of Target ellipse, so that Target ellipse includes complete Portion track.At this point, executing step 207.If confirming in whole tracks and the tracing point being located at outside Target ellipse enclosed region being not present, Then illustrate that Target ellipse has contained whole tracks, at this point, without the dimension data for adjusting Target ellipse, therefore, Ke Yijie Beam operation.

Whole tracks are determined as handwriting trace by step 207.

Further, whole tracks are determined as handwriting trace, and Target ellipse enclosed region will be located in handwriting trace Interior tracing point is denoted as the first tracing point, is denoted as the second rail for the tracing point outside Target ellipse enclosed region is located in handwriting trace Mark point.

Step 208, mobile Target ellipse, so that the second central point weight of the first nodal point of Target ellipse and handwriting trace It closes, the second central point is the central point of the minimum circumscribed rectangle of handwriting trace.

Specifically, determining the minimum circumscribed rectangle of handwriting trace.Wherein, minimum circumscribed rectangle refers to comprising handwriting trace Whole tracing points and the smallest rectangle of area.Further, the method for determination embodiment of minimum circumscribed rectangle is not construed as limiting.Example Such as, the whole tracing points for obtaining handwriting trace select an outermost tracing point from upper and lower, left and right four direction respectively, into And minimum circumscribed rectangle is determined according to four outermost tracing points.Further, it after determining minimum circumscribed rectangle, determines minimum outer It connects the central point of rectangle and is denoted as the second central point.Wherein, the method for determination embodiment of the second central point is without limitation.For example, For minimum circumscribed rectangle, connect the midpoint of two long sides and the midpoint of two short sides, and using the intersection point of two lines as Second central point.

Further, before this step, the first nodal point of the second central point and Target ellipse that determine handwriting trace is No coincidence.If not being overlapped, this step is executed, if being overlapped, executes step 209.In general, after response person's handwriting control operation, book The first nodal point of the second central point and Target ellipse of writing track is not overlapped.At this point, mobile Target ellipse, so that the first center Point and the second central point are overlapped, i.e., the center of Target ellipse and minimum circumscribed rectangle is overlapped.For example, Fig. 3 is the embodiment of the present invention Two the first display schematic diagrams provided.With reference to Fig. 3, the second central point 311 and target of the minimum circumscribed rectangle 31 of handwriting trace The first nodal point 321 of ellipse 32 is respectively two positions.Further, the mobile Target ellipse 32 of interactive intelligent tablet computer, so that First nodal point 321 and the second central point 311 are overlapped, at this point, Fig. 3 becomes Fig. 4, Fig. 4 is provided by Embodiment 2 of the present invention the Two display schematic diagrams.Compared to Fig. 3, the relative position of handwriting trace and Target ellipse is more reasonable in Fig. 4.It should be noted that real In the application of border, the central point of minimum circumscribed rectangle and each figure is only the consistency operation of interactive intelligent tablet computer, will not be in display screen Middle display shows that minimum circumscribed rectangle, first nodal point and the second central point are merely for convenience of understanding in Fig. 3.

It is understood that handwriting trace can also be moved other than mobile Target ellipse, so that first nodal point and the Two central points are overlapped.Since the person's handwriting control operation that handwriting trace is issued according to user obtains, handwriting trace is usually shown In the desired position of user, therefore, compared to mobile handwriting trace, mobile Target ellipse is more reasonable.

Step 209 judges in handwriting trace with the presence or absence of the second tracing point being located at outside Target ellipse enclosed region.If book The second tracing point for existing in track and being located at outside Target ellipse enclosed region is write, 210, otherwise, end operation are thened follow the steps.

Specifically, handwriting trace may be integrally incorporated in Target ellipse closure after in view of mobile Target ellipse In region, it is also possible to which there is also the second tracing points being located at outside Target ellipse in handwriting trace.Therefore, in mobile Target ellipse Afterwards, the whole tracing points for needing to traverse handwriting trace again, obtain the location of pixels of each tracing point, and by the location of pixels and mesh Elliptical pixel region is marked to be compared.The location of pixels of at least one tracing point is then said in the outside of pixel region if it exists There is the second tracing point outside the enclosed region of Target ellipse in bright handwriting trace, at this time, it may be necessary to carry out to Target ellipse It is enlarged, i.e. execution step 210.The location of pixels of at least one tracing point is then said in the outside of pixel region if it does not exist Each tracing point is the first tracing point in the enclosed region of Target ellipse in bright handwriting trace.At this point, no longer needing to pair Target ellipse amplifies operation, that is, terminates this operation.

Step 210 amplifies operation to Target ellipse, so that whole tracing points of handwriting trace are located at target after amplification In elliptical enclosed region.

Specifically, amplifying operation to Target ellipse.In embodiment, retouched so that equal proportion amplification target is oval as an example It states.Optionally, in handwriting trace, select the elliptical first nodal point of distance objective apart from farthest tracing point, and draw packet Minimum ellipse figure containing the tracing point, the central point of the minimum ellipse figure are that first nodal point later puts Target ellipse It is big to be extremely overlapped with minimum ellipse figure.It is also optional, it is based on handwriting trace, draws the minimum ellipse figure of each tracing point, and The amplifying parameters of Target ellipse are determined according to minimum ellipse figure.

Specifically, the step specifically includes step 2101- step by taking the minimum ellipse figure for drawing each tracing point as an example 2103:

Step 2101 draws the corresponding ellipse figure to be selected of each tracing point in handwriting trace, and ellipse figure to be selected is packet Minimum ellipse figure containing corresponding tracing point, the central point of ellipse figure to be selected are first nodal point, the of ellipse figure to be selected First length shaft length ratio of the two length shaft lengths than being equal to the Target ellipse.

Specifically, successively selecting each tracing point of handwriting trace, and draw the ellipse figure to be selected of each tracing point.Its In, the corresponding ellipse figure to be selected of each tracing point.Ellipse figure to be selected is the point centered on first nodal point, and includes The minimum ellipse figure of corresponding tracing point.Further, ellipse figure to be selected and Target ellipse are similar fitgures, i.e., will be to be selected ellipse The length shaft length ratio of circle diagram shape is denoted as the second length shaft length ratio, and the second length shaft length ratio and the first length shaft length ratio It is equal.

It is understood that first nodal point can replace mutually with the second central point in this step.

In general, after determining the corresponding ellipse figure to be selected of each tracing point, it is available relative to first nodal point Multiple concentration ellipses.By taking Fig. 4 as an example, after determining the corresponding ellipse figure to be selected of each tracing point, the third of available Fig. 5 is aobvious Show schematic diagram.Wherein, what Fig. 5 was merely exemplary the show ellipse figure to be selected of 3 tracing points, in practical application, each tracing point There is corresponding ellipse figure to be selected.It is understood that Fig. 5 is the calculating process of interactive intelligent tablet computer, in user's operation mistake It will not be shown in display screen in journey.

Step 2102, according to all ellipse figures to be selected, determine the amplifying parameters of Target ellipse.

Specifically, ellipse figure to be selected may be considered the pixel region to be selected when Target ellipse includes corresponding tracing point. Accordingly, according to whole ellipse figures to be selected, the amplifying parameters of Target ellipse are determined.Wherein, amplifying parameters can be for mesh Elliptical magnification ratio is marked, the amplified dimension data of Target ellipse, i.e. target size data are also possible to.The class of amplifying parameters When type difference, corresponding determining scheme is different.Accordingly, include at least one following scheme in embodiment:

Scheme one, the program are directed to the case where amplifying parameters are amplification ratio, at this point, the step specifically includes: step 21021- step 21024:

Step 21021, the first length data for obtaining semiaxis to be selected in each ellipse figure to be selected, semiaxis to be selected is to be selected short Semiaxis or major semiaxis to be selected.

Specifically, major semiaxis is denoted as major semiaxis to be selected in ellipse figure to be selected, in ellipse figure to be selected semi-minor axis be denoted as to Select semi-minor axis.Semiaxis to be selected is the major semiaxis to be selected or semi-minor axis to be selected in corresponding ellipse figure to be selected.In embodiment, with to be selected Semiaxis is to be described for the semi-minor axis to be selected in corresponding ellipse figure to be selected.

Illustratively, the length in pixels of semi-minor axis to be selected in each ellipse figure to be selected is obtained, and is denoted as the first length data. Specifically, determining semi-minor axis to be selected according to the location of pixels on the side of ellipse figure to be selected, later, determine that semi-minor axis to be selected is corresponding Pixel length, and be denoted as the first length data.

Step 21022, the lenth ratio for calculating each first length data with the second length data of target semiaxis, target Semiaxis is and the corresponding target semi-minor axis of semi-minor axis to be selected or target major semiaxis corresponding with major semiaxis to be selected in Target ellipse.

Specifically, major semiaxis is denoted as target major semiaxis in Target ellipse, semi-minor axis is denoted as target semi-minor axis in Target ellipse. Further, target semiaxis refers in Target ellipse for the semiaxis with semiaxis computational length ratio to be selected.When semiaxis to be selected is When semi-minor axis to be selected, target semiaxis is target semi-minor axis.When semiaxis to be selected is major semiaxis to be selected, target semiaxis is that target is long by half Axis.

Further, due to by taking semi-minor axis to be selected as an example, target semiaxis is target semi-minor axis in this step.Specifically , second is denoted as according to the length in pixels of the available target semi-minor axis of the dimension data of Target ellipse, and by the length in pixels Length data.Calculate separately the lenth ratio of each first length data and the second length data.In general, lenth ratio can indicate The scaling relationships of corresponding semiaxis between ellipse figure to be selected and Target ellipse.

Step 21023, in whole lenth ratios, select the maximum lenth ratio of numerical value.

Illustratively, lenth ratio is bigger, illustrates that the semi-minor axis to be selected of ellipse figure to be selected is longer, ellipse figure to be selected Area is bigger, and enclosed region includes that the tracing point quantity of handwriting trace is more.Therefore, in embodiment, select numerical value maximum Lenth ratio.At this point, the area of ellipse figure to be selected is maximum, the quantity of the tracing point for the handwriting trace that enclosed region includes is most It is more.In general, the corresponding ellipse figure to be selected of the maximum lenth ratio of numerical value includes oval the second farthest tracing point of distance objective.

Step 21024, using the maximum lenth ratio of numerical value as the amplification ratio of Target ellipse.

Specifically, the corresponding ellipse figure to be selected of the maximum lenth ratio of numerical value includes oval second farthest of distance objective Tracing point, at this point it is possible to think that the enclosed region of the ellipse figure to be selected includes whole tracing points of handwriting trace.Therefore, if The ellipse that sets the goal is amplified according to the amplification ratio, and is overlapped after amplifying with ellipse figure to be selected.

For example, the maximum lenth ratio of numerical value is 2, at this point, the amplification ratio of Target ellipse is 2.According to the amplification ratio When amplifying to Target ellipse, the major semiaxis length in pixels and semi-minor axis length in pixels of Target ellipse are put and are twice.

The case where scheme two, the program for amplifying parameters are Target ellipse amplified dimension data, at this point, the step It specifically includes: step 21025- step 21026:

Step 21025, in all ellipse figures to be selected, select maximum ellipse figure to be selected.

Specifically, maximum ellipse figure to be selected can be it is farthest apart from first nodal point in all ellipse figures to be selected Ellipse figure to be selected, i.e., with one heart in ellipse figure to be selected outermost ellipse figure to be selected.In general, maximum ellipse to be selected The area of figure is maximum, and enclosed region includes that the quantity of the tracing point of handwriting trace is most, it can is thought comprising whole Handwriting trace.Further, the selection mode embodiment of maximum ellipse figure to be selected is without limitation.For example, selection outermost Ellipse figure to be selected, the maximum ellipse figure to be selected of selection area, the length in pixels of selection major semiaxis to be selected it is longest to be selected The longest ellipse figure to be selected of length in pixels of ellipse figure or selection semi-minor axis to be selected.

Step 21026, using the dimension data of maximum ellipse figure to be selected as the target size data of Target ellipse.

Specifically, target size data refer to the amplified dimension data of Target ellipse.Due to needing to put Target ellipse It is big to be extremely overlapped with maximum ellipse figure to be selected.Therefore, using the dimension data of maximum ellipse figure to be selected as target size Data.After determining target size data, directly the dimension data of Target ellipse can be adjusted to target size data.

It is understood that in practical application, it can also be by the pixel of the major semiaxis to be selected of maximum ellipse figure to be selected Length and the length in pixels of semi-minor axis to be selected are as target size data.At this point, can directly be adjusted when amplifying to Target ellipse The target major semiaxis and target semi-minor axis of Target ellipse are to corresponding length in pixels.

It is step 2103, oval according to amplifying parameters amplification targets.

Specifically, can be when according to amplifying parameters amplification target ellipse and determine that Target ellipse adjusts according to amplifying parameters Dimension data afterwards, and then Target ellipse is amplified.It can also be and determined on the side of Target ellipse respectively according to amplifying parameters The adjustment data (the A pixel on such as side moves up B pixel) of pixel, and according to adjustment data to Target ellipse into Row amplification.

In the present embodiment, using the location of pixels of tracing point and Target ellipse as calculating reference data, in practical application, also It can be using the coordinate position of tracing point and Target ellipse as calculating reference data.
