Embodiment

Following examples are used to illustrate the present invention, but do not limit the scope of the invention.

Embodiment 1

Be illustrated in figure 1 as the present invention and be used for schematic flow sheet the handwriting processing method on the information processing terminal, this information processing terminal comprises hand input device, data storage device, data presentation device and data communication equipment (DCE) at least in the present embodiment, and this method comprises following key step:

(1) at first the user is specifying handwriting input person's handwriting in the big or small zone by hand input device on the information terminal, and simultaneously, hand input device is the original handwriting data of the collection user of unit handwriting input with the point;

(2) after the input of each monocase is finished, the form and the size of the original handwriting data of the monocase gathered are carried out normalized, and with the handwriting data storage of the monocase that obtains after the normalized in data storage device;

(3) the handwriting data with the monocase after the normalized output to data presentation device, and data presentation device is according to the monocase handwriting of sequencing after the display process of window viewing area of user's input;

(4) user also can edit and revise in handwriting input the person's handwriting of the input content that shows in the display window in the display device, promptly the handwriting data of the monocase of data store memory storage is edited and retouching operation accordingly;

(5) after the affirmation input is all finished, the handwriting data after the normalized that shows in the data presentation device directly are converted to picture format;

(6) the handwriting data of the picture format that obtains in the step (5) are sent to the communication terminal of appointment by data communication equipment (DCE).

The hand input device of the information processing terminal has touch-screen in the present embodiment, in step (1), gather user's original handwriting data by touch-screen, wherein the hand input device of the information processing terminal is not limited to have touch-screen, also can be other handwriting input device.

Present embodiment, when in step (1), gathering each monocase person's handwriting, determine that the foundation that the input of each monocase is finished is: whether the time interval of pausing according to user's handwriting input greater than given threshold value t, or is that given symbol is judged finishing of monocase input according to the handwriting input person's handwriting.

Have according to prior art on the information processing terminal of hand input device specific handwriting input zone is arranged, at data presentation device the hand-written hand-written viewing area that drags track of demonstration is arranged, and handwriting input zone and hand-written viewing area be a multiplexing zone fully, like this person's handwriting track that the user can its input of real time inspection before monocase is finished.Data presentation device in the present embodiment also comprises the viewing area of the handwriting data after the normalized that is presented at reception in the step (3).

Provide two kinds of input patterns in the present embodiment, wherein a kind of input pattern is full frame input pattern, as shown in Figure 2 at the handwriting input zone of hand input device under this pattern and the complete multiplexing same window in viewing area of the handwriting data after the data presentation device demonstration normalized, left-half shows for the window that does not write person's handwriting among Fig. 2, and right half part is the window demonstration when writing person's handwriting among Fig. 2; Another kind of input pattern is the grid input pattern, the viewing area of the handwriting data after the demonstration normalized of the handwriting input of hand input device zone and data presentation device is split up into two zones at same window under this pattern as shown in Figure 3, the handwriting input zone of described hand input device is divided at least one and writes lattice, there are two to write lattice among Fig. 3, left-half shows that for the window that does not write person's handwriting right half part is that the window when writing person's handwriting shows.

Therefore present embodiment will carry out the person's handwriting collection in different ways according to these two kinds of input patterns characteristics separately, be handwriting gatherer process under two kinds of input patterns of present embodiment as accompanying drawing 4.Its process is as follows: when the user clicks on by the touch-screen of writing pencil at the information processing terminal and drags writing pencil, should at first judge the current input pattern of enabling, if full frame input pattern should write down and draw the track that writing pencil drags on whole screen window; If the grid input pattern, and be provided with plurally when writing lattice, need then to judge that user's the first stroke is clicked and whether the coordinate points that begins to drag drops on specific writing in the zone; When this coordinate points drops on when writing in the lattice 1, system is the starting point record with this point and draws the tracing point that the user drags in writing lattice 1 by writing pencil, by that analogy, when this coordinate points drops on when writing in the lattice n, system is the starting point record with this point and draws the tracing point that the user drags in writing lattice n by writing pencil.

The method of wherein judging the current input pattern of enabling is: in data storage device stores the corresponding symbol of representing input pattern is arranged, according to starting corresponding input pattern by the hand input device incoming symbol; Wherein a kind of input pattern can certainly be set for the acquiescence start-up mode, not import the user under the situation of this symbol and import by default mode.In addition, the method of the track that record and drafting writing pencil drag on whole screen window is: gather hand-written original person's handwriting by hand input device, the original handwriting data of storage in data storage device, in the regional multiplexing hand-written viewing area of data presentation device and handwriting input according to the original person's handwriting of position display of handwriting input.

In the present embodiment, original handwriting can be stored in the data storage device, and in memory storage, set up the corresponding relation of the handwriting data after hand-written original person's handwriting and the normalized, by this corresponding relation, when the user clicks person's handwriting after the normalized by hand input device in data presentation device, can in writing lattice, demonstrate the original handwriting corresponding with it by this corresponding relation.

The purpose of handwriting input original character data being carried out normalized in step (2) has two: the one, because the character of user's handwriting input varies, the person's handwriting that has needs " expansion " (writing more greatly), what have then needs " contraction " (writing forr a short time), have only the flexible and adjustment that it is made appropriateness, font just can be more reasonable, attractive in appearance; The another one reason is after carrying out normalized, and the shape of person's handwriting is in controlled while, and its size has also obtained unification simultaneously, and the person's handwriting after the conversion always can be littler than the person's handwriting of direct handwriting input.Therefore this in a way conversion process makes and makes the restricted problem of handwriting input area be improved owing to terminal device touch-screen area is less.

Has a kind of normalized pattern in the present embodiment at least, and it is default mode that a kind of normalized pattern is arranged, the storage mode parameter corresponding in data storage device with each normalized, wherein the normalized process is that each the monocase handwriting data that will collect carries out normalized by normalization pattern parameter to its size and form, the user is not when selecting the normalized model, by the mode parameter in the normalized pattern of acquiescence the size and the form of original handwriting data are carried out normalized, the user selects the normalized pattern before writing after, the size and the form of original handwriting data are carried out normalized by the mode parameter in the normalization pattern of selecting.

During concrete enforcement, the corresponding different symbol of each normalized model, in storer, store the data message of these symbols in advance, when representing the data message of one of them normalized pattern consistent in the data message that the symbol of user by hand input device input obtains after gathering and the storer, think that then the user has selected this normalized model, otherwise the size and the form of original handwriting data are carried out normalized by the parameter in the normalized pattern of acquiescence.

The benefit of setting multiple normalized pattern in the present embodiment is that the user can select the normalized pattern as required, and different conversion process patterns is owing to there is different mode parameters, thereby different to the adjustment degree of the size of original person's handwriting and form.This mode parameter can be given default parameters, also can be set according to individual demand by the user.For example, if display device resolution 240 * 320 pixels, the mode parameter of acquiescence can be unified with the demonstration size of all characters after the normalization, it is adjusted to 20 * 20 pixel sizes, and the user also can adjust to 30 * 30 pixels or 32 * 32 pixels etc. with all characters after the normalization.Therefore in the present embodiment, all characters that the user writes in writing lattice are after normalized, and the height when it shows is consistent with width.

To be present embodiment carry out synoptic diagram before the normalized to some monocase person's handwritings to accompanying drawing 5A, and Fig. 5 B carries out effect comparison figure after the normalized for embodiment to some monocase person's handwritings.As can be seen from the figure: original monocase handwriting data is through after the normalized, these monocase person's handwritings have obtained unification except height and the width at font, the height of its normalization font and width can change, font after the normalization has also obtained correspondingly adjusting and beautifying in addition, thereby realized optimization, solved unbalance and big or small skimble-scamble problem that handwriting characters exists monocase person's handwriting form.

The left side of accompanying drawing 6 is the data presentation window interface of data presentation device on the information processing terminal of present embodiment, because present embodiment specifically is being divided into the capable and v row of u with the viewing area window in the data presentation device in the performance history, the viewing area can be divided into u * v rectangular area by dividing, specifically can be referring to the right half part of accompanying drawing 6, among the figure as can be seen: only show a monocase person's handwriting in each rectangular area, under the multipage editor situation, each page or leaf in the content display window can show u * v monocase person's handwriting at most, multipage is compiled as prior art, no longer describes in detail herein.

Owing to set multiple normalization pattern in the present embodiment, in the adjustment degree difference of different normalization pattern lower word symbols, the therefore corresponding line number u that window is divided under different mode is different with columns v.

Consider that the user may edit and revise the person's handwriting content of having imported, as inserting operations such as space, carriage return, deletion and modification person's handwriting, demonstration should correspondingly be adjusted and refresh to the content display region in the data set.Therefore need in data storage device, set up the handwriting data that a handwriting information table record user has imported, so that system is according to the content in the content display window in the variation refresh data device in the handwriting information table.In the specific implementation process, in view of the internal memory of present mobile communication equipment limited, in order to reduce the user in the process of editor and modification content, system retrieval and searching the time that the handwriting information table is consumed, the data storage device in the present embodiment adopt structure of arrays to administer and maintain in handwriting data after the normalized and the data presentation device mapping relations between each rectangular area in the viewing area.

Be illustrated in figure 7 as in the data storage device in the array and data presentation device the mapping relations figure between each rectangular area in the viewing area, concrete grammar is:

At first, because present embodiment adopts prior art can realize the multipage editor, range of pages is limited in the s, therefore can use an index bound to come storage address information as the array of u * v * s, under the starting condition, the equal assignment of each element in the array is empty, and after the content of user importation, the subscript value of array will point to the handwriting back end after the normalized of this storage of array;

At least should comprise in the foregoing handwriting back end information: this person's handwriting is the handwriting data after corresponding position information and the corresponding normalized in content display region, and described positional information should comprise: page number, row number and row number;

Thus, should there be following relation position of person's handwriting node in the subscript value of the array element viewing area pointed with it:

Subscript value=(k-1) * u * v+ (m-1) * u+n

K described in the formula, m, n represent that this array element person's handwriting node pointed should be presented at the rectangular area that is positioned at the capable and n row of m of k page or leaf in the content display window.

After the user whenever finishes the input of a character, can increase a new handwriting back end automatically in the data storage, and, go out the positional information of new node in content display region according to the positional information calculation in the last handwriting back end simultaneously with in the handwriting information of the handwriting data recording after the normalization to the node.

Show a monocase person's handwriting like this in each rectangular area of data presentation device, when the continuous handwriting input of user, according to the mapping relations between each rectangular area in the viewing area of the array of the handwriting data of storage after the normalized in the data storage device and data presentation device, can be from left to right, the monocase person's handwriting of rule from top to bottom after with normalization be shown in the described rectangular area successively.

After setting up above-mentioned mapping relations, present embodiment utilizes these mapping relations can carry out suitable editor to the character of having imported in step (4), concrete grammar is: when existing certain monocase person's handwriting is made amendment in the user need be to the content display window, can click and need select the monocase person's handwriting of modification by hand input device, can in data presentation device, use frame of broken lines or the outstanding selected person's handwriting of other colors according to prior art, and directly calculate this character subscript value x of corresponding array in the handwriting information table in data storage device according to the position of its click and the page number in the current window, according to editor's type the handwriting data of storage of array in the data storer is done corresponding operation.Be specially:

If 1, this moment, the user re-entered new monocase person's handwriting by hand input device, system will directly find selected character pairing array element in structure of arrays according to subscript value x, and upgrade corresponding normalization handwriting information in this element node pointed, substitute selected character script information with the handwriting information data of pointing to after the new normalized that obtains after the step (2) then;

As Fig. 8 A be depicted as to character substitute when operation substitute before array and the viewing area mapping relations synoptic diagram in the display device in the data storage device, as Fig. 8 B be depicted as to character substitute operate after array in the data storage device and the mapping relations synoptic diagram of the viewing area in the display device.

2, need return when deleting character as the user, in data presentation device, choose last character to carry out back and delete operation, automatically deletion and destroy in the data storage device that last array element is not empty person's handwriting node in the handwriting information table, and be sky with its assignment;

Present embodiment is to utilize to grab the screen technology and convert plurality of pictures in step (5), and picture format can adopt: be JPEG picture compression form, or be image exchange lattice GIF compressed format, or be the compressed format etc. of TIFF picture format.

Present embodiment is in step (6), and data communication equipment (DCE) sends to the communication terminal of appointment with the normalization person's handwriting of picture format in the mode of multimedia message, so as long as can support the terminal device (being mobile communication equipment) of multimedia message can both receive pictorial information.

Wherein, transmission of grabbing screen and multimedia message recited above is prior art.

Realize the system construction drawing of this method as shown in figure 12 for the present invention, the short arrow that tail end indicates open circles among the figure is represented handwriting data information, and the transmission of handwriting data between each module reflected the whole process that person's handwriting of the present invention is handled and sent indirectly.Among the figure as can be seen: system of the present invention mainly by: the mutual primary module of UI, person's handwriting acquisition module, conversion process module, data memory module, display module, editing and processing module, format converting module and sending module are formed.In the present embodiment in the system function of each module as follows:

The mutual primary module of UI: be mainly used in the interactive operation between realization system and the user, system can realize the calling of other functional module by this module, comprising: person's handwriting acquisition module, conversion processing module, data memory module, display module, editing and processing module and sending module;

Whole interface mainly is made of two parts in the present embodiment: write lattice, content display window.The wherein said lattice of writing are that system offers the appointed area that the user imports person's handwriting specially, and the user is in handwriting input, and the person's handwriting of user's handwriting input will be drawn and gather in system also by it; The content display window is in order to the user handwriting after the demonstration normalized, i.e. the Edition Contains input area of system; In addition, system also is provided with the person's handwriting content of auxiliary function buttons control in order to have imported in modification and the content of edit display window in the interface of this module, as: insert space, line feed, return and delete, remodify or the like.

The information processing terminal in the present embodiment is not limited to have the terminal of data communication equipment (DCE), overcomes in the past owing to the less problem that makes that the user writing area is restricted of equipment handwriting input region area there not being data communication equipment (DCE) to utilize method of the present invention that the handwriting input pen mark is handled also can to reach.

Embodiment 2

Because the Chinese character that the user writes in writing lattice is single discrete person's handwriting, to be combined into the multipage literal after these monocase person's handwriting normalization, in order to make every piece of person's handwriting seem more similarly is in the effect that links up on one page paper under writing, and the invention provides embodiment 2.Have system architecture and the treatment scheme identical among this embodiment,, just in demonstration, adopted different processing procedures the conversion process of monocase person's handwriting and person's handwriting referring to accompanying drawing 1 and Figure 12 with embodiment 1.

Shown in Fig. 9 A, write the complete multiplexing same window in viewing area in zone and the data presentation device in the hand input device among this embodiment, write the zone and be matts, adopting the purpose of matts is for the monocase person's handwriting of writing is carried out preliminary classification, in step (1) in the gatherer process, if the user is written character in whole matts, system can handle it automatically as word; If the user writes in the field wordbook is write any four little lattice in the lattice, promptly can be used as punctuate (as: comma, fullstop, colon etc.) and handle.

Can also adopt the viewing area of writing in zone and the data presentation device in the hand input device shown in Fig. 9 B to be split up into two zones among this embodiment at same window, this embodiment writes the zone and is divided into 2 writing units, this writing unit is similarly matts, can carry out preliminary classification to the monocase person's handwriting of writing.

In the present embodiment, the conversion process module of system is also focused on from the relative position and the big or small effect of adjusting the entire chapter person's handwriting demonstration of demonstration that show between word and the word when the monocase person's handwriting is carried out normalized.After preserving data-carrier store by input media collection user's handwriting and with it, in translation process during to its normalized, present embodiment provides two kinds of methods of determining the relative size of conversion back word, a kind of method is directly to be controlled the size of monocase person's handwriting after the normalization by the user, promptly provides the field wordbook to write lattice to the user.The user writes the monocase write on the lattice and the relative size of matts at the field wordbook, has determined the final size of word after the conversion process; If the user writes punctuation mark in the field wordbook is write any four little lattice of lattice, system can be less punctuate with its conversion process automatically.That this method is suitable for is very confident to the person's handwriting of writing of oneself, do not wish that system adjusts the user of person's handwriting size automatically.

Another kind method is to be decided the final size of each monocase person's handwriting of conversion back by system's (being the algorithm in the conversion process module).This method is not only at the current monocase of writing of user, but is kept at all characters in the data storage device at what the user write.Its basic process is as follows: when the user has whenever write a monocase, the conversion process module can be carried out initial normalized to it, and the monocase information that other conversion process of front in the relevant information of font size after its normalization and the storer are crossed merges, draw the statistical information of the profile size of current all monocases, calculate a rational matts (not showing) according to this statistical information, this matts just in time envelope is lived maximum in a statistics monocase.The monocase (comprising punctuation mark) that current all conversion process are crossed compares with the size of this matts and draws fiducial value, and the size of the monocase of current all conversion process being crossed according to fiducial value is once more carried out suitable adjustment.Whenever write a character and carry out the situation that Integratively adjusts except foregoing, system also can import some monocases (as: after importing a line character) back the user and carry out foregoing statistics adjustment process.

In addition, adjust in the current input character size in translation process, present embodiment is also adjusted the relative position that shows between word and the word.Present embodiment is by calculating the centre of gravity place of each word, the center of gravity of all words (except the punctuate) roughly is on the same horizontal line, it is indefinite that the demonstration of every so capable word just can not rise and fall, and also can produce a kind of in picturesque disorder aesthetic feeling between word that varies in size and the word.In the writing of reality, narrower after some monocase conversion process, broad after some monocase conversion process, if output to successively in the rectangular area that is divided on the display screen according to the method among the embodiment 1, the word that can occur some broads unavoidably seems compact, and some narrower words seem more sparse, in order to improve this effect, make the monocase write seem to be unlikely to too sparse also as for too compact from entire chapter, this implementation basis word is wide to be adjusted the word that shows on the display screen and the distance between the word.In the present embodiment, both relations are: if writing is narrower, then the distance between left and right of word is less; If the writing broad, then the distance between left and right of word is bigger.Excessive for the difference that prevents the distance between word and the word, during adjustment, should make the wide ratio of the spacing of narrower word and word more greatly, the wide ratio of the spacing of more fat word and word is littler.Line space as for every capable word can be considered directly to be regulated and control on the interface by the user.Concrete method is: obtain the wide a1 of actual word after each monocase conversion process according to the handwriting data of being stored in the data storage device, calculate left spacing a2 and the space on right a3 corresponding with this monocase according to the wide a1 of the actual word of monocase, left spacing a2, the space on right a3 of the wide little monocase of word is respectively less than left spacing a2, the space on right a3 of the roomy monocase of word; Each storage of monocase handwriting data back and the wide a data of the corresponding demonstration of this monocase word in described data storage device, the wide a1+ space on right of a wide a=left side actual word of spacing a2+ of the demonstration word of this character a3; When showing monocase successively to the screen of the information processing terminal according to the wide data of described demonstration word of monocase, be the space on right a3 that is spaced apart previous monocase between adjacent two monocases and the left spacing a2 sum of a back monocase, as shown in Figure 13.Utilize preceding method to the user write all characters carry out conversion process after, because the wide a1 difference of actual word of each word, therefore also there is gap in its left spacing a2, the space on right a3 that determines, like this, except the demonstration height b unification of word, the wide a of demonstration word of each monocase will be uneven.For example, the demonstration size of word can be 30 * 30 pixels, also can be 28 * 30 pixels, 20 * 30 pixels etc. after the conversion process.

In addition, consider the attractive in appearance of writing, present embodiment identify the handwriting carry out conversion process in, also beautify and taked following disposal route respectively from the level and smooth of person's handwriting and the effect that shows.

Identifying the handwriting and do smoothing processing, is because the user in the written handwriting, the hard turnover of person's handwriting can occur, the phenomenon of sampling point distributions inequality unavoidably on handwriting input device.Present embodiment adopts interpolation and resampling technology to solve the problem of sampling point distributions inequality; Use curve-fitting method can make person's handwriting become more level and smooth.

On the final display effect of person's handwriting, if the sampled point of person's handwriting is coupled together demonstration with line segment singlely, because the restriction of machinery and equipment resolution, writing can produce sawtooth unavoidably when showing, the smoothing processing of identifying the handwriting like this will fall short of success for lack of final effort.Present embodiment adopts anti-aliasing display technique that the value of the color of each point directly is set, and by different color values, utilizes the visual characteristic of human eye, makes the person's handwriting after the conversion process seem that the edge is more level and smooth.When needing, the result of person's handwriting output can be used as image output.

Because after utilizing the described method of present embodiment that the monocase person's handwriting is carried out conversion process, the wide meeting of demonstration word of character becomes inhomogeneous, and can change at any time, so the display module of present embodiment adopted with embodiment 1 noted earlier comparatively diverse ways show monocase person's handwriting after the conversion process.Detailed process is described below:

(1) at first with content display region from vertically being divided into v elongated rectangular shape zone, as shown in figure 10, each elongated rectangular shape zone can be divided into the rectangular area that some width differ once more according to the wide a of demonstration word of each monocase in the data storage device, in order to each the monocase person's handwriting after the demonstration conversion process.The display width a sum of every capable monocase is less than or equal to the width of elongated rectangular shape.

(2) still to adopt index bound be that the structure of arrays of certain value administers and maintains the corresponding relation between each elongated rectangular shape zone in handwriting data and the content display region to present embodiment, as shown in figure 11.Under the starting condition, the equal assignment of each element in the array is empty, after the content of user importation, and the monocase handwriting data node of the part element in the array after with some conversion process of the interim storage of pointing system.At least should comprise in the described in the present embodiment handwriting data nodal information: this person's handwriting corresponding position information in content display region is respectively: the information of the right corner point horizontal ordinate of page number, row number and the corresponding rectangular display area of this individual character person's handwriting and the handwriting data of correspondence thereof.Whenever finish writing of a character, system is new node of application automatically, and the handwriting data after the conversion process is recorded in the handwriting information in the node, go out the display position of new node in content display region according to the positional information calculation in the last array element person's handwriting node pointed simultaneously.

After the user whenever writes a Chinese character or several Chinese characters, if system adjusts relative position and the size that shows between the word and word in the entire chapter person's handwriting automatically, the corresponding information in the handwriting data node that can upgrade in time of the handwriting information table in the data storage device; Correspondingly, when the content in the handwriting information table changes, corresponding with it writing in the automatic refreshing content of the display module meeting viewing area.

Identical with embodiment 1, in the present embodiment, the user still can carry out suitable editor, modification to the content of having imported in written handwriting, comprise the transmission of last person's handwriting.The detailed process of its realization can be referring to corresponding with it content among the embodiment 1.

Though the present invention specifically illustrates and illustrates in conjunction with a preferred embodiment; but the personnel that are familiar with this technical field are appreciated that; wherein no matter still can make various changes in detail in form, this does not deviate from spirit of the present invention and scope of patent protection.
