Description

手写文字输入方法及装置 Handwritten character input method and apparatus

技术领域 FIELD

[0001] 本发明涉及一种在形成于显示画面表面的触摸屏上进行手写输入的手写文字输入方法及其装置,特别涉及一种在手写文字输入中,手写输入部的显示画面区域内没有可供添笔的地方时,能够调整并形成添笔空间的手写文字输入方法及手写文字输入装置。 [0001] The present invention relates to a forming method and apparatus for handwritten characters input handwriting input on the touch screen display of the screen surface, particularly to a handwritten character input, the display screen is not available in the area of ​​the handwriting input unit when Tim local pen, and can be adjusted handwritten character input handwritten character input method and apparatus for forming a space pen added.

背景技术 Background technique

[0002] 现有的导航装置能够利用GPS检测出当前位置,计算出由该当前位置到达通过各种方法输入的目的地的引导路线,之后沿着该引导路线将车辆安全的引导至目的地。 [0002] can utilize a conventional GPS navigation device detects the current position calculated by the arrival of the current position of the input by various methods guidance route to a destination, after the vehicle along the guide route to the destination secure boot. 在进行目的地的设定时,可运用各种检索方法,例如,通过省市区县乡镇(日本的都道府县)来逐渐缩小检索范围从而进行地址设定的地址检索方法、通过输入公共设施、商店或者餐饮店等设施名称的读法来进行检索的名称检索方法、或者通过输入上述设施的电话号码来检索的电话号码检索方法、根据医院、火车站、宾馆、公园等分类来缩小目的地检索范围的分类检索方法、检索事先进行了标记的地点、家、设施等的标记点检索方法等。 During setting of the destination, may be retrieved using a variety of methods, e.g., by narrowing the search range by provincial towns counties (prefectures in Japan) to perform address setting address retrieval method, by inputting a common facilities, shops, restaurants and other facilities or the name of the readings for name retrieval method retrieval, or retrieval method to retrieve a phone number by entering a phone number to the facilities, according to the classification of hospitals, railway stations, hotels, parks and other purposes to narrow classification retrieval method retrieval range, the retrieval mark in advance the location of the home, facility, etc. marker retrieval methods.

[0003] 在进行这些检索时,针对地址、分类的检索,多采用从上位项目开始逐渐缩小检索范围,从显示在屏幕上的下位项目,任选其一的检索方法。 [0003] During the search for an address retrieval, classification, began to use more narrow the search items from the host from the display items on the lower screen, optionally one of the search method. 另外,如果直接检索特定的地址、 或者直接检索已知设施名称时,可直接输入其拼音进行检索,此时通过遥控器的按键、或者通过触摸屏功能在显示于屏幕上的字母表中逐一进行拼音字母的选择来进行输入操作。 Further, if directly retrieve a specific address, or facility name retrieved directly known, which can be directly input phonetic searching, in case one by one phonetic alphabet displayed on a screen by remote control key, or by a touch panel function selected for letter input operation.

[0004] 这样在触摸屏上逐一进行拼音字母的选择来实现输入的情况下,也可以采用手写文字输入方法来进行文字的输入,即通过手写输入用笔或者手指在显示屏上的文字输入画面内书写,将书写后的笔迹显示在显示画面上,用户在确认该笔迹地基础上进行输入确认从而实现希望文字的输入。 In the case [0004] carried out by alphabet selection on the touch screen one by one to achieve input handwritten character may be used to enter text input methods, i.e. by intra input handwriting with a pen or a finger on a display screen of text writing, the handwriting was written on the display screen, a user input confirmation confirming to achieve desired text input based on the handwriting.

[0005] 上述各种检索方法及输入方法都各有所长,通常不存在最合适的方法。 [0005] The various search methods have their own merits and the input methods, the most appropriate method generally does not exist. 特别是上述导航装置并不是指在特定国家使用,而是分别在各个国家生产,或者出口到各国家被广泛使用。 In particular, does not refer to the use of the navigation device in a specific country, but are produced in various countries, or exported to countries are widely used. 因此,例如在美国可以通过字母输入来直接检索特定的设施名,日本则可以通过输入罗马字母、假名变换成汉字来检索含有汉字的设施名等输入检索方法被广泛使用。 Thus, for example, in the United States may be retrieved directly by a specific letter POI name input by the input Japan Roman alphabets, kana into kanji characters to retrieve the name of the facility contains an input retrieval method and the like are widely used.

[0006] 同样,在我国,由于设施名几乎都是由汉字组成的,设施等检索时主要采用通常在电脑输入中使用的拼音输入法以及五笔输入法。 [0006] Similarly, in China, due mainly Pinyin input method and Wubi input method commonly used in computer input when the facilities were almost always composed of Chinese characters, and retrieval facilities. 由于被广泛使用的拼音输入法是通过从字母表选择、输入构成汉字发音的拼音来进行汉字输入,而上述字母被对应分配到键盘的各个按键上的,因此对于不经常接触键盘的人来说,利用导航装置进行设施检索时,设施名称的输入经常要花费很长时间。 Since the Pinyin input method is widely used to input Chinese characters by characters from the phonetic alphabet pronunciation configuration selection, input, and said letters are assigned to correspond to the respective keys of the keyboard, so for people who are not regular contact with the keyboard when the facility searching using a navigation device, enter the name of the facility often takes a long time. 并且,五笔输入法是通过将汉字的偏旁部首拆开,分别输入与其对应的按键来进行汉字输入的,使用该输入法更是要记住所有偏旁部首所对应的按键, 对于一般的导航装置使用者是非常难于利用的。 Further, by the stroke input method of Chinese character radicals apart, are input keys corresponding to input Chinese characters, the input method is used to remember all the key corresponding radicals, for general navigation It means the user is very difficult to use.

[0007] 在这样的情况下,将显示屏的显示画面作为手写输入的功能部,通过直接在该画面上书写文字笔迹来进行文字输入,利用事先做成的手写输入文字识别用数据库对上述输入的文字笔迹进行识别的手写文字输入方法,对于任何人来说都是比较容易且及其有效的文字输入方法。 [0007] In this case, the display portion of the display screen as a function of handwriting to text input handwritten characters by writing directly on the screen, using beforehand to handwriting character recognition of the input database handwritten character input method of character handwriting recognition, are relatively easy for anyone and its effective text input method. 这种手写文字输入方法,不仅在我国,在日本、韩国也作为有效的输入方法被广为利用。 This handwritten text input method, not only in our country, in Japan, South Korea as an effective input method is widely used.

[0008] 另外,在专利文献1中公开了一种技术,当进行手写文字识别时,如果输入的文字列不能全部显示在规定区域内,就将最后输入的文字以外的文字列的显示尺寸暂时缩小, 暂时能够完全显示于上述规定区域内。 [0008] Further, in Patent Document 1 discloses a technique of, when handwritten character recognition, if the input character can not be displayed all columns other than the display size of the text characters in a predetermined area, will be the last column of the input is temporarily narrow, temporarily it can be fully displayed in the predetermined region. 并且,专利文献2公开了一种能够反映在原图像数据上进行添笔、修改的结果,从而实现高速显示输入笔迹的现有技术。 Further, Patent Document 2 discloses a pen can reflect be added in the original image data, the modified result, prior art in order to achieve high-speed display of the input handwriting. 专利文献3公开了如下的现有技术:在手写输入区域内设定手写输入用的基准格,并设定输入基本区域及该输入基本区域周围的扩张区域,在该区域整体上检出手写文字笔迹,之后使其收纳于基本区域内。 Patent Document 3 discloses the following prior art: setting the handwriting input area of ​​the handwriting input with the reference grid, and set the input of the input region and the base region surrounding the base region expansion, detection region handwritten character on the whole handwriting, after which it is accommodated in the region group.

[0012] 上述现有的手写文字输入装置是例如像图12所示那样进行文字输入的。 [0012] The conventional handwritten character input means is for example as shown in FIG. 12 as text input. S卩,如图12(a)所示的手写输入例,在手写输入“梁”字时,在液晶屏幕表面贴触摸屏而形成的手写输入部51上,用手指或笔尖等进行所谓的手写输入。 Handwriting input unit 51 S Jie, handwriting (a), an input embodiment shown in FIG 12, when the handwriting input "beam", which is formed in a touch screen LCD screen attached to the surface, so-called handwritten input with a finger or stylus . 此时的汉字输入就是将文字图形一笔一笔地进行手写输入。 At this point is the Chinese character input text graphics one stroke handwriting input.

[0013] 由手写输入文字识别的处理方法,将手写输入的文字图形中的细小的凸凹部去掉,将直线、规定的曲线进行变换从而生成识别用文字图形,将其与手写输入文字识别用数据库中存储的标准文字图形进行比较,得出两个文字图形的相似度,并将候选文字按照相似度高低的顺序进行提示。 [0013] a processing method handwriting character recognition, the fine convexo-concave portion character pattern handwriting input is removed, the linear, predetermined curve transformation thereby generating identification character pattern, which is the handwriting character recognition database standard character pattern stored in the comparison, the similarity between two characters and graphics, prompts and candidate characters in accordance with the level of sequence similarity. 因此,如前所述将“梁”字一笔一划地进行输入,每输入一笔都重新进行文字的识别处理,并连续的将当次识别处理的结果的候选文字按照相似度高低的顺序进行显示。 Thus, the previously described "beam" one stroke character input, each input brushstroke re character recognition process, and continuously will result when the second candidate character recognition processing according to the level of sequence similarity display.

[0014] 图12(a)示出了汉字“梁”下方的“木”字还没有被输入时的情形,手写输入至此, 作为现阶段识别结果的候选文字被显示在图中所示的候选文字显示部52。 [0014] FIG. 12 (a) shows the case when the bottom of the kanji "wood" has not been inputted word "beam", the handwriting input so far, a candidate is displayed as shown in FIG stage recognition result candidate characters text display section 52. 此时,由于候选文字显示部52上并没有显示使用者想要的“梁”字,所以如图12(b)所示使用者又在下方输入了“木”。 In this case, since the candidate character display desired by the user and does not show the word "beam" upper portion 52, so that FIG. 12 (b) shown below and a user inputs "timber." 这时的文字识别结果,在候选文字显示部52上,使用者所希望的“梁”字被显示在最前边的位置上,使用者确认之后通过用手指的触摸操作等对候选文字“梁”进行了选择。 In this case the character recognition result, the candidate character in the display unit 52, a user desired "beam" word is displayed at the position on the front most, after the user confirms the candidate word by touching with a finger operation "beam" We were selected. 据此,如图12(c)所示,确定文字显示部53上显示被选择文字“梁”,手写输入部51的手写文字笔迹以及候选文字的显示都被消去,进入下个文字的手写输入处理。 Accordingly, FIG. 12 (c), the determination on the character display unit 53 displays the selected character "beam", the handwritten character stroke and a display candidate character handwriting input section 51 have been eliminated, enter the next character handwriting input deal with.

[0015] 像这样进行手写输入时,例如在手写输入上述“梁”字的文字图形时,很多时候在最初并没有考虑到文字整体的平衡,而是想到哪儿写到哪儿。 [0015] When the handwriting input like this, for example, in the above-mentioned handwriting input text graphics word "beam", many times in the first and did not take into account the overall balance of the text, but think of where to where to write to. 并且,很多手写文字输入装置都不能确保有足够大的输入区域(手写输入部51的画面区域)。 Further, many of the handwritten character input device can not ensure a sufficiently large input area (screen area of ​​the handwriting input unit 51). 在这种情况下,很容易出现例如如图12(d)所示的状况,即在手写输入部51的画面区域内没有供可输入“木”字的空间。 In this case, (d), for example, the situation illustrated in FIG. 12 is prone, i.e., can not enter the space for "wood" word in the screen area of ​​the handwriting input section 51. 只手写输入到图12(d)所示的程度,由所输入的手写文字笔迹而生成的识别用文字图形与手写输入文字识别用数据库中存储的“梁”字的标准文字图形的相似度太低,因此在候选文字显示部52上不能显示出使用者所希望的“梁”字。 Handwriting input only to the extent shown in FIG. 12 (d), a handwritten character input handwriting recognition input generated by the character recognition similarity too standard character pattern word "beam" stored in the database with the handwritten character pattern low, and therefore can not display "beam" word desired by the user in the candidate character display unit 52. 这时,显示的候选文字中既没有使用者想要的文字,手写输入部51上也没有可供添笔用的空间,所以只能消去至此输入的手写文字笔迹返回至初始画面,考虑文字整体的平衡后如图12(a)所示从手写输入部51 的区域的上方开始重新输入比上次输入的尺寸小的文字图形。 In this case, the candidate character display neither the character the user wants, the handwriting input unit 51 does not add the space for the pen, so far only erasing handwriting input handwritten character is returned to the initial screen, the entire text considered (a), starting from the upper region of the handwriting input unit 51 to re-enter the smaller size than the previous input character pattern 12 after balance.

[0016] 特别是在面积很小的手写输入部51上输入笔画数很多的复杂的汉字时,经常会发生手写输入还没有完成,手写输入部51上可供添笔的空间却不足的状况,此时使用者就不得不重新进行输入,非常的不便。 When the [0016] Enter the number of strokes especially a lot of complex Chinese characters on a small area of ​​the handwriting input section 51, often occur handwriting input is not yet complete, adding the situation was less than pen space available on the handwriting input section 51, At this time, users will have to re-enter, very inconvenient. 在汉字输入以外,例如韩国语等其他语种的输入也会发生同样的问题。 Outside Chinese character input, such as input in other languages ​​such as Korean language will be the same problem occurs.

[0017] 因此,本发明的目的就是提供一种手写文字输入方法及手写文字输入装置,在进行文字的手写输入时,即使在文字图形还没有输入完成就发生手写输入部的添笔空间不足的情况,也没有必要进行文字图形的重新输入,能够容易得进行添笔输入操作。 [0017] Accordingly, an object of the present invention is to provide a handwritten character input handwritten character input method and apparatus, when performing the handwriting input text, yet less than the input character pattern is completed even if the handwriting input pen unit occurs Tim space case, there is no need to re-enter the characters and graphics, can be easy to get Tim pen operation.

[0060] 候选文字显示处理部19进行如下处理:将由手写输入文字识别部10对手写输入文字笔迹5进行文字识别后得到的候选文字在上述候选文字显示部6上显示。 [0060] candidate character display processing unit 19 performs processing: by the input handwritten character recognition unit 10 for the handwriting input handwritten characters 5 candidate characters obtained in the above-described character recognition candidate character displayed on the display unit 6. 而且,确定文字显示处理部20进行如下处理:如前所述使用者从候选文字中任选其一时,或者任一文字被选择指示后由手写输入确定指示部17进行确定指示时,该文字被作为确定文字显示在确定文字显示部7上。 Further, the processing unit 20 determines the display character performs processing: As described above the user from the candidate text which optionally one o'clock, any text or word is determined by the selection instruction indicating the handwriting input unit 17 determines an indication, as the character is determining the character displayed on the character display unit 7 is determined. 显示于确定文字显示部7的一连串的确定文字列作为确定文字数据33被存储于后述存储部30中。 Determining a series displayed in the text display character is determined as the determining portion 7 of the column 33 after the character data is stored in the storage unit 30 described later.

[0061] 手写输入消去部22进行如下处理:例如当一个文字的手写输入处理完毕,且文字的输入被确定时,消去显示在手写输入显示部3的先前输入的手写输入笔迹。 [0061] erasing handwriting input unit 22 performs processing: for example, when a handwritten character input processing is completed, and when the input character is determined, erasing the display of the previously entered handwriting input unit 3 handwriting input handwriting. 除此之外,在手写输入文字笔迹不能被进行文字识别时,或者即使被识别也显示不出想要输入的候选文字等情况下,为了促使使用者进行再次输入而结束识别处理,将显示的手写输入文字笔迹消去。 In addition, when the handwriting input character handwriting character recognition can not be performed, or even if identified can not displayed like the case where the candidate character to be input, to prompt the user to again input recognition processing ends, the display handwriting input handwritten characters eliminated. 此时,候选文字显示部上有文字显示的话,也同时消去该显示文字。 In this case, the candidate text characters are displayed, then the display, and also display text on the erased portion.

[0062] 输入空间不足检出部23进行检出以下状态:位于手写输入显示部3的画面框4中的手写输入未完成阶段的手写输入文字笔迹在画面框4内(手写输入检出部2内)处于写不下的状态,或者将要处于写不下的状态。 [0062] The input detection unit 23 is insufficient space for detecting the following states: handwriting input handwriting input is located in the screen frame of the display unit 3 is not 4 stages of completion handwriting input handwritten characters in the screen frame 4 (handwriting input detecting unit 2 inside) in writing no less than the state, or will not be written in the state. 根据上述检出,后述的手写输入文字笔迹显示调整部34调整手写输入中的手写输入文字笔迹的显示。 According to the above detection, the handwriting input handwritten characters described later display adjustment unit 34 adjusts the handwriting input handwriting input handwritten characters. 输入空间不足检出部23可通过各种方法检出输入空间(添笔空间)不足。 Insufficient input space detecting section 23 can detect the input space (the space pen Tim) insufficient by various methods. 其中,可由手写输入文字笔迹画面框接触检出部M 通过上述检出方法检出手写输入中的手写输入文字笔迹与画面框4相接触,从而判断为输入空间不足。 Wherein the handwritten input character by handwriting detecting portion contacting the screen frame handwriting input character M 4 is in contact with the screen frame handwriting input handwritten detected by the above detection method, thereby determining the input insufficient space.

[0063] 而且,当使用者的手写输入进行到中途且处于没有显示候选文字的状态下,或者候选文字显示之后,通过手写输入停止后经过规定时间检出部25检测出规定时间内(例如7秒)没有进行手写输入文字笔迹的添笔操作以及候选文字的选择操作、并且也没有进行其他任何操作时,推定为上述输入空间不足。 [0063] Moreover, when the handwriting input state of the user and is in no way to display the candidate character or candidate character display, by a predetermined time elapsed after the detection unit detects the handwriting input within the predetermined stop time (e.g., 725 sec) no selection operation handwriting input pen to add handwritten characters and the candidate characters, and also without any other operations, presumed to be less than the input space. 该处理也可以与上述手写输入文字笔迹画面框接触检出部M的处理相结合进行,例如当检测出手写输入文字笔迹5与画面框4相接触,且之后规定时间内使用者没有进行任何操作时,判断为输入空间不足。 This processing of handwritten characters may be input screen frame above the handwriting contact detector combination for M, for example, when the contact 4 is detected handwriting input handwritten characters and the screen frame 5, and after a predetermined period of time without any user operation when it judged insufficient input space.

[0064] 而且,设定包围手写输入中的手写输入文字笔迹的外边框,通过手写输入文字笔迹外边框面积比检出部沈检测出上述外边框所包围的面积占画面框4的面积的比例在规定值以上时,就判断为上述输入空间不足或者不足的可能性很大。 [0064] Further, an outer frame surrounding the set of handwriting input handwriting input handwritten characters, handwritten characters by handwriting outer border area than the detection portion detects the sink area surrounded by the outer border area occupies the screen frame ratio of 4 is above a predetermined value, it is determined that a great possibility of inadequate or insufficient in the input space. 为了进行上述处理,当例如如图11(a)所示进行手写输入时,外边框检出部27如图11(b)所示那样检测出画面框M 的手写输入文字笔迹的上下方向上以及左右方向上的各个最突出的点,将检测出的各点用水平线以及垂直线连接成四边形,将该四边形作为手写输入文字笔迹外边框进行设定。 In order to perform the above-described process, when, for example FIG. 11 (a) handwriting input, the upper in FIG. 11 (b) detects the vertical direction of the screen frame M handwriting input handwritten characters outer frame portion 27 as shown in detecting and the most prominent point of the respective left and right directions, the respective points detected by the horizontal and vertical lines are connected to a quadrilateral, quadrangle as the handwriting input handwriting to text frame set.

[0065] 图11(c)体现了手写输入文字笔迹外边框检出方法的其他实例。 [0065] FIG. 11 (c) Other examples reflect the handwriting input method for detecting the outer border of the handwritten characters. 在该实例中,以手写输入文字笔迹的中心(重心)为基准,将各个方向上的最突出的部分作为突出点进行抽出,连接抽出的各突出点而形成的多边形被作为手写输入文字笔迹外边框进行设定。 In this example, the handwriting input handwritten characters to the center (center of gravity) as a reference, the most prominent part in the respective directions as the projecting points for extraction, drawn connecting the projecting points of the polygon is formed as an outer handwriting input handwritten characters border set. 如此,可以采用多种方法设定手写输入文字笔迹外边框。 Thus, various methods can be used to set the handwriting input handwriting to text frame. 外边框面积计算部28计算由上述外边框检出部27检出的手写输入文字笔迹外边框的框内面积,外边框面积比计算部四利用存储部30中存储的输入画面面积数据31,计算手写输入文字笔迹外边框的框内面积与画面框4(图8至图11的符号54)的框内面积的比。 Outer border area calculating section 28 calculates the input by the outer frame portion 27 detected by detecting the handwritten character stroke borders the outer frame area, the frame area outside the screen 30 than the input data stored in the storage unit by using four calculating unit area of ​​31, calculated handwriting input handwriting to text frame border of the frame area of ​​the screen (reference numeral 54 in FIG. 8 to FIG. 11) of the frame 4 is the area ratio. 如果由此得到的面积比大,即相对于画面框4内的面积,手写文字输入笔迹外边框内的面积占规定比例以上时,判断为输入空间不足。 If the area ratio thus obtained, i.e., with respect to the area within the screen frame 4, handwritten character input box outside the handwriting area accounts for more than a predetermined ratio, determines that the shortage of the input space.

[0066] 在存储部30中,除了存储了上述输入画面面积数据31之外,还存储了将手写输入文字笔迹5的各笔迹用坐标数据进行表示的手写输入文字笔迹数据32,如后所述将手写输入文字笔迹移动、缩小显示时,读出该手写输入文字笔迹数据32,对其进行在画面框4中的移动处理或者缩小处理。 [0066] In the storage unit 30, in addition to the above input screen stored in the data area 31, 32 is also stored, as the handwriting input handwritten characters after each stroke 5 is represented by the coordinate data input handwritten character stroke data the handwriting input handwritten characters moved, zoomed, reads the handwritten input character stroke data 32, its movement in the picture processing block 4 or the reduction process. 存储部30中的确定文字数据33是如上所述按照被确定的先后顺序显示于确定文字显示部7上的一连串确定文字列的数据,该数据可被用于后述的为了进行导航装置目的地设定而进行的设施名输入等。 Determining the character data storage section 30 as described above is 33 in the order determined according to a determination that the text display navigation device determines a destination for data series of character string on the portion 7, the data can be described for the rear display the facilities were set name input and so on.

[0067] 手写输入文字笔迹显示调整部34具备显示位置调整部35、显示尺寸调整部42,其中,显示位置调整部35大致被分成自动调整部36和手动调整部39。 [0067] The handwriting input handwriting character display adjusting unit 34 includes a display position adjustment unit 35, the display size adjustment unit 42, wherein the display position adjustment portion 35 is substantially divided into the automatic adjusting unit 36 ​​and the manual adjustment section 39. 当上述手写输入文字笔迹画面框接触检出部M检测出手写输入中的手写输入文字笔迹与画面框4相接触时,上述自动调整部36中的手写输入文字笔迹画面框接触位置检出部37检测出上述接触处是位于矩形画面框4的哪一条边上,并使手写输入文字笔迹自动向接触边的相反侧移动。 When said handwriting input handwriting character M the screen frame contact detector detects handwriting input handwritten character input handwriting and the screen frame 4 contacted 36 of the automatic adjusting unit in the handwriting input character handwriting position detecting portion contacting the screen frame 37 the contact is detected at which one of the rectangular sides of the screen frame 4, and the handwriting input handwritten characters automatically moves to the opposite side of the contact edge. 例如, 手写输入中的手写输入文字笔迹与画面框4的下方的边相接触时,将到那时为止所输入的手写输入文字笔迹的整体向画面框4内的上方移动并显示。 For example, handwriting input handwritten input when the whole side of the screen below the text handwriting frame 4 is brought into contact, until then the handwritten input of handwritten characters input in the upward movement of the screen frame and the display 4.

[0068] 并且,当上述输入空间不足检出部23检测出画面框4内(手写输入检出部2内) 的输入空间不足时,自动调整部36的手写输入文字笔迹部首等识别调整部38进行下述处理:判断已输入的手写输入文字笔迹如果作为手写输入文字识别用数据库11中的汉字的部首等,在什么位置上存在的几率高,并根据该判断结果向特定方向移动上述手写输入文字笔迹。 Insufficient [0068] Further, when the space is less than the input detection unit 23 detects the intra frame 4 (within the handwriting input detection unit 2) of the input space, the automatic adjusting unit 36 ​​in the handwriting input character handwriting recognition, etc. Header adjusting portion 38 performs the following process: determining whether handwriting input has been entered as handwriting input handwritten characters if the character recognition characters radicals database 11, a high probability exists in what position, and moves in a specific direction based on the determination result of the handwriting input handwritten characters. 例如,成为“左偏旁”的几率高时,使手写输入文字笔迹向画面框4内的左侧移动以便确保右侧的输入空间(添笔空间),同样的,成为“右偏旁”的几率高时使手写输入文字笔迹向右侧移动,成为“字头”的几率高时使手写输入文字笔迹向上方移动,成为“字底”的几率高时使手写输入文字笔迹向下方移动。 For example, becomes "radical left," the probability is high, so that movement of the handwriting input handwritten characters left in the screen to the frame 4 in order to ensure the input space (the space pen Tim) to the right of, the same, the probability of becoming "right radical" high when handwriting input handwritten characters so moved to the right, so that the handwriting input handwritten characters become moved downward when the high probability is high that the handwriting "prefix" handwriting input text moves upward to become the "end of the word" chance. 在这里除了可以判断输入中的手写输入文字笔迹成为哪种部首的几率高之外,还可以进行下述处理:将该手写输入文字笔迹作为汉字的一部分进行识别,并判断该部分在手写输入文字识别用数据库11中的各种汉字的什么位置上存在的几率高。 In addition to this determination input handwriting input handwritten characters which become to high probability of radicals, the following may also be treated: the recognition of handwritten characters as part of the handwritten input characters, and determines whether the handwriting input portion high probability of the presence of what position the various characters 11 on the database by the character recognition.

[0069] 即使在通过上述自动调整部36不能对输入中的手写输入文字笔迹的位置进行自动调整的情况下,也能够通过手动调整部39根据用户的意图,将手写输入文字笔迹以手动的形式进行任意的移动。 [0069] Even in the case of automatic adjustment by the position can not enter handwritten characters input in handwriting of the automatic adjusting unit 36, it is possible according to user's intention, the handwriting input handwritten characters by the manual adjustment section 39 are manually form arbitrary movement. 移动方向指示检出部40检测使用者的例如操作8方向键开关或者操作触摸屏的方向显示键等的操作动作。 Indicating the moving direction detection unit 40 detects a user operation, for example, a direction key switch 8 or the operation of the touch panel display operation of an operation key or the like. 而且,拖拽检出部41检测使用者的拖拽操作, 即使用者在触摸屏上用手指触摸已输入的手写输入文字笔迹的一部分,并将其向画面上所希望的方向拉拽的操作。 Further, a drag detection section 41 detects a user's drag operation, i.e., a portion of the user on the touch screen with a finger touch input is handwriting input handwritten characters, and the desired direction on the screen of the pulling operation. 通过这些移动方向指示检出部40、拖拽操作检出部41检出进行了手写输入文字笔迹的移动操作时,通过手动调整部39使手写文字输入笔迹向使用者指定的方向移动。 When the detection unit 40 indicates, the operation detecting portion 41 detecting a drag performed handwriting input handwritten characters operated by movement of the moving direction, the manual adjustment section 39 so that the handwriting input handwritten character moves in the direction designated by the user.

[0070] 如前所述显示位置调整部35进行手写输入文字笔迹的显示位置的调整时,手写输入文字笔迹显示调整部34的显示尺寸调整部42进行将该手写输入文字笔迹整体缩小显示等的显示尺寸的调整。 [0070] As described earlier position adjusting unit 35 adjusts the handwritten input character display positions of the handwriting, the handwritten text handwriting input display adjusting unit 34 to adjust the display size of the handwriting input section 42 for overall reduced display of handwritten characters or the like resizing the display. 此时,还可以进行下述处理:手写输入文字笔迹越向画面框4的角部移动,与其对应其缩小率就越大等。 In this case, the following processing may be performed: handwriting input handwritten characters is moved to the corner portion of the screen frame 4, corresponding to a reduction ratio which is greater the like. 另外,即使上述显示位置调整部35没有进行手写输入文字笔迹的显示位置的调整,该显示尺寸调整部42也可以将该手写输入文字笔迹在相同位置上进行缩小,从而确保之后的画面框4内的输入空间(添笔空间)。 Further inside the screen frame after, even if the above display position adjustment unit 35 adjusts the display position of the handwritten input of handwritten characters is not performed, the display size adjustment section 42 may be reduced at the same position on the handwriting input handwritten characters, thus ensuring 4 the input space (Tim pen space).

[0071] 另外,如图1右下方画面框4内的手写输入文字笔迹显示例18所示,18-1体现了在手写输入汉字“梁”时,没有空间以供使用者输入其下方笔迹“木”字的情形,18-2体现了将已输入的手写输入文字笔迹以自动或者手动的方式边向画面框4的上方移动边缩小,从而形成添笔空间的情形,18-3体现了在该添笔空间中添笔输入“木”字的情形,18-4体现了最终汉字“梁”被正确输入的状态。 [0071] Further, the lower right hand in FIG. 1 intra frame 4 handwriting input character shown in the display cases 18, 18-1 reflects the handwriting input when the character "beam", there is no room for the user to input handwriting below " wood case "word, 18-2 reflects the handwriting input handwritten characters entered automatically or manually moved to the top of the screen side frame 4 narrow sides, thereby forming a space pen case Tim, 18-3 reflects the the case of Tim Tim pen pen space "wood" word, 18-4 reflects the final status of the Chinese character "beam" is correctly entered.

[0072] 如图1所示功能框所形成的本发明能够通过图2〜图7所示的工作流程以各种形态进行实施。 [0072] The present invention is shown in functional blocks in Figure 1 can be formed by the workflow shown in FIG. 2 ~ 7 carried out in various modes. 在图2所示的手写输入文字识别处理的实例中,最初在手写输入部中手写输入文字笔迹(步骤Si),之后通过输入空间不足检出部23进行如图3所示的输入空间不足的检出处理(步骤S2)。 Input handwritten character recognition processing example shown in Figure 2, the initial handwriting input handwritten characters handwriting input unit (step Si), then the input is less than the space 23 through the input detection unit is less than the space shown in FIG. 3 The detection process (step S2).

[0073] 然后判断是否检出输入空间不足(步骤S3),检测出输入空间不足时,进入步骤S4。 [0073] then determines whether the input space is less than the detection (step S3), detects that the input space is insufficient, proceeds to step S4. 在步骤S4中,由自动调整部36判断是否可能进行手写输入文字笔迹的自动移动处理, 可能进行自动移动处理时进入步骤S11,进行图5所示的输入空间不足时的手写文字笔迹的自动移动处理。 In step S4, by the automatic adjusting section 36 determines whether or not the automatic scroll process may be handwriting input handwritten characters, the process proceeds to step S11 when the automatic scroll process may be performed when a handwritten character handwriting input is insufficient space shown in FIG. 5 of the self-moving deal with. 另外,本实施方式的步骤S4中,在如下情况下判断为可能进行手写输入文字笔迹的自动处理:在步骤S2的输入空间不足检出处理中检测出手写输入文字笔迹于画面框4接触的情况,或者,将基于已输入的手写输入文字笔迹通过识别用文字图形生成部9生成的识别用文字图形与存储在手写输入文字识别用数据库11中的各文字(汉字) 的标准文字图形进行比较,手写输入文字笔迹是汉字部首或者汉字的一部分的概率在所定值以上的情况。 Further, the step S4 of the present embodiment, in the case where the automatic determination processing handwriting input handwritten characters are possible: processing handwriting input is detected in contact with the screen frame handwriting character input space 4 at step S2, detection of inadequate or the input of handwritten characters based on the handwriting entered by identifying identifying handwriting input character with a recognized character pattern generating unit 9 with the character pattern stored is compared with each character 11 database (Chinese characters) of standard character pattern, handwriting input handwritten characters is the probability of a portion of Chinese radicals or characters in the case of a predetermined value or more. 除上述情形之外判断为不能进行自动移动处理。 Other than the above can not be determined that the automatic scroll process.

[0074] 另一方面,由步骤S4判断为不能进行手写输入文字笔迹的自动移动处理时,将与步骤S3中没有检测出输入空间不足时相同,进入步骤S5,由手动调整部39判断使用者是否进行手写输入文字笔迹的移动操作。 When [0074] On the other hand, can not be determined at step S4 handwriting input handwritten characters automatic scroll process, the step S3 is not detected in the same input space is insufficient proceeds step S5, the manual adjustment section 39 determines the user whether handwriting input handwritten characters move operation. 这里使用者通过操作8方向键、触摸屏的方向显示键来指示手写输入文字笔迹的移动,移动方向指示检出部40、拖拽操作检出部41检测出上述操作时,进入步骤S12,根据移动指示进行手写输入文字笔迹的移动处理。 Here the user when displaying the operation key 8 through the direction arrow keys, a touch screen to indicate movement, the moving direction of the handwriting input handwritten characters indicating the detection portion 40, a drag operation detection unit 41 detects the operation proceeds step S12, the mobile It instructs the mobile handwriting input processing of handwritten characters. 在该步骤S12的手写输入文字笔迹的移动时,为了确保足够的输入空间(添笔空间),优选的进行改手写输入文字笔迹的缩小处理。 In step S12 moves the handwriting input handwritten characters, in order to ensure sufficient input space (Tim pen space), it is preferably modified reduction processing handwriting input handwritten characters.

[0075] 步骤S5中判断为使用者不进行手写输入文字笔迹的移动操作时,以及在步骤S12 的手写输入文字笔迹的手动移动及缩小处理进行之后,进入步骤S6,根据已输入的手写输入文字笔迹进行文字的识别处理。 After the processing performed when the [0075] Step S5, it is determined that the user does not input a handwritten character stroke movement operation, and handwritten characters input at step S12 and manually moved handwriting reduction proceeds step S6, the input character entered handwriting handwriting character recognition process. 该文字识别处理进行以下处理:将已输入的手写输入文字笔迹由识别用文字图形形成部9去除细小的凸凹,使之变换成直线或者规定的曲线,从而形成识别用文字图形,然后将该识别用文字图形与手写输入文字识别用数据库11中存储的各文字的标准文字图形相比较,从手写输入文字识别用数据库11抽出与上述识别用文字图形的相似度在规定值以上的文字。 The character recognition process performs the following processing: the entered handwritten character handwriting input unit 9 is formed by removing the fine irregularities character pattern recognition, so that a straight line or into a predetermined curve, thereby forming a character pattern recognition, the recognition and compared with a standard character pattern of each character stored in the database 11 the input character pattern and the handwritten character recognition, text extracted from the identification value by more than a predetermined degree of similarity with the character pattern database 11 from the handwriting character recognition. 然后,判断上述手写输入文字识别用数据库11中是否存在与上述手写输入文字笔迹的相似度在规定值以上的文字(步骤S7),如果判断为不存在该文字时进入步骤S13,进行图6所示的不能识别输入文字时的处理。 Then, determining whether the handwriting character recognition database 11 whether there is the above-described handwriting input handwritten characters similarity in character than a predetermined value (step S7), it is determined if the character does not exist into the step S13, the diagram 6 the processing shown in the input character can not be recognized.

[0076] 由步骤S7判断未存在该文字时进入步骤S8,按照识别率(与上述标准文字图形的相似度)高低的顺序在候选文字显示部6上显示该文字。 Proceeds to step S8 when [0076] the presence of the character is not determined in step S7, in accordance with the recognition rate (similarity with the above standard character pattern) at the level of the candidate character sequential display section 6 displays on the character. 之后,在步骤S9中判断使用者是否从候选文字显示部6上显示的候选文字中选择了一个候选文字,若判断并没有进行选择时,进入步骤S14,进行图7所示的未选择候选文字时的处理。 Thereafter, in step S9, the user determines whether the candidate text unit 6 displays the selected candidate characters from a candidate character display, if no selection is determined, and proceeds step S14, shown in Figure 7 for the non-selected candidate characters processing of. 反之,由步骤S9判断为进行了候选文字的选择时,将被选文字作为手写输入文字进行确定(步骤S10),将该确定文字通过确定文字显示处理部20显示于确定文字显示部7。 Conversely, when it is determined in step S9 has been selected candidate characters, the text will be selected as the handwritten input character determination (step SlO), the processing unit 20 determines the display character displayed on the character display unit 7 is determined by determining the text.

[0077] 图2中步骤S2的输入空间不足检出处理如图3所示,最开始判断手写输入文字笔迹是否与画面框4相接触(步骤S21)。 [0077] FIG input space is insufficient in Step 2 S2 detection process shown in Figure 3, initially determines whether handwriting input handwriting character 4 is in contact with the screen frame (step S21). 此时的与画面框4是否相接触的判断虽然是基于上述各种检测方法而进行的,但是也可以采用下述处理更早的检测出输入空间不足:当画面框4是手写输入显示部3的显示区域的外周边缘或者手写输入检出部2的输入区域的外周边缘的边界线,通过由触摸屏输出的接触位置坐标检测出手指或者笔接触了与该边界线相重合的位置的方法来检出手写输入文字笔迹与画面框4相接触时,将上述境界线设定在上述手写输入显示部3的显示区域的外周边缘或者手写输入检出部2的输入区域的外周边缘的稍内侧。 At this time, the screen frame and determines whether the contact 4, although based on the various detection methods are carried out, but the following process may be employed earlier detected input space is insufficient: the screen frame when the handwriting input display section 4 is 3 an outer peripheral edge or a handwriting display area of ​​the input outer peripheral edge of the input region detecting portion 2 of the boundary line, by detecting a contact position coordinates of the touch screen output of a finger or a pen in contact with the boundary line coinciding position of approach to the subject when the handwriting input handwriting character frame 4 into contact with the screen, the above-described boundary line set in the outer peripheral edge of the handwriting input area or display the handwriting input display section 3 an outer peripheral edge of the input region of the detecting portion 2 slightly inside.

[0078] 由步骤S21判断手写输入文字笔迹与画面框4相接触时,进入步骤S26,检测出输入空间不足。 [0078] When the handwriting input is determined at step S21 and the character handwriting contacting the screen frame 4 proceeds step S26, the detected input space insufficient. 反之,由步骤S21判断手写输入文字笔迹没有与画面框4相接触时,进入步骤S22,判断手写输入是否停止了规定时间(例如7秒等)。 Conversely, when the determination in step S21 handwriting input handwritten characters not in contact with the screen frame 4 proceeds step S22, it is determined whether or not the handwriting input is stopped for a predetermined time (e.g., 7 seconds). 具体的,通过手写输入停止后规定时间经过检出部25,判断在手写输入操作中途停止后,规定时间内没有进行手写输入文字笔迹的添笔操作以及候选文字的选择指示操作或者其他任何操作。 Specifically, the handwriting input by a predetermined time after stop detection unit 25, determines the handwriting input operation stopped on the way, there is no predetermined input handwritten character handwriting pen and the candidate add text selection, or any other instruction operation within the operation time. 这里判断手写输入停止后规定时间内没有进行任何操作时,进入步骤S26,推定由于输入空间不足,导致使用者长时间迟迟无法进行下面的操作,从而判断输入空间不足。 Where a determination is stopped after a predetermined time the handwriting input operation without any time, enter the step S26, the input estimated due to lack of space, resulting in long delays in user performs the following operations, so that the input space is determined insufficient. 然后通过步骤S25返回图2的步骤S3,进行是否检出输入空间不足的处理的判断及其以后的处理。 Then returns to step S25 via step 2 of FIG S3, the process determines whether the input space is insufficient and the subsequent detection process.

[0079] 步骤S22中判断手写输入停止后没有经过规定时间时,由图示步骤S23判断是否进行根据手写输入文字笔迹的外边框面积比例来检出输入空间不足的处理,如果事先进行了进行上述处理的设定时进入步骤S24,进行如图4所示的根据手写输入文字笔迹的外边框面积比例进行输入空间不足的检出处理。 When the [0079] determination in step S22 after the predetermined time has not elapsed handwriting input is stopped, the step S23 shown to detection process determines whether the input space according to the ratio is less than the outer border area of ​​the handwriting input handwritten characters, if the above-described advance setting process enters step S24, the input for lack of space for FIG detection processing in accordance with the ratio of the area of ​​the outer frame 4 handwriting input handwritten characters shown.

[0080] 反之,由步骤S23判断为事先没有设定进行上述处理时,由步骤S25返回图2的步骤S3,继续进行是否检出输入空间不足的处理的判断及其以后的处理。 When [0080] On the contrary, the determination in step S23 is not set in advance for the above-described process, the step S25 returns to step S3 of FIG. 2, determination processing whether to continue the input space is insufficient and the subsequent detection process.

[0081] 图3的步骤SM所进行的根据手写输入文字笔迹的外边框面积比例来检出输入空间不足的处理如图4所示,首先检出手写输入文字笔迹的外边框(步骤S31)。 Input space according to the ratio to the detection area of ​​the outer frame handwriting input processing of handwritten characters is insufficient step [0081] FIG. 3 is performed SM 4, handwriting input is first detected handwritten characters outer frame (step S31). 该动作是由图1的输入空间不足检出部23中手写输入文字笔迹外边框面积比检出部沈的外边框检出部27来检测的,具体的,通过对于上述图11(a)所示的手写输入文字笔迹进行如图11(b) 或者如图11(c)所示的处理来检测外边框。 This operation is less than the input space of FIG. 1 in the handwriting input detection unit 23 detecting an outer frame portion handwriting to text heavier than the frame area detection section 27 detects, in particular by the above-described FIG. 11 (a) is handwritten character handwriting input shown in FIG. 11 (b) or the process shown in FIG. 11 (c) detecting an outer frame.

[0082] 然后,外边框面积计算部观计算由步骤S31检测出的外边框内的面积(步骤S32),之后,外边框面积比计算部四计算相对于手写输入画面(画面框4内)的整体面积, 手写输入文字笔迹外边框内的面积所占比例(步骤S3;?)。 [0082] Then, the outer border area calculating unit calculates a step S31 Concept detected frame outside the area (step S32), then, the outer border of the area ratio calculation section with respect to the four handwritten input screen (the screen frame 4) is overall area, the handwriting input handwritten characters outside the frame area percentage (step S3 ;?). 此时,外边框面积比计算部四将由外边框面积计算部观计算的外边框面积及存储在存储部30的输入画面面积数据31读出,计算两个面积的比值。 At this time, the area of ​​the outer frame and the outer frame storage area calculation unit calculating ratio calculating unit area of ​​the outer frame concept by four in the storage unit 30 the input screen area 31 reads the data, calculate the ratio of the two areas.

[0083] 之后,在步骤S34中判断相对于手写输入画面面积文字笔迹外边框内面积所占比例是否在规定值以上,若判断为在规定值以上时,由步骤S35检出输入空间不足。 After [0083] In step S34 is determined with respect to the screen for handwritten input character handwriting area frame outside the area proportion of not less than a predetermined value, it is determined if the predetermined value or more, step S35 detected by the lack of input space. 之后与上 After previous

14述步骤S34中判断为上述比值不在规定值以上时相同,通过步骤S36进入图2的步骤S3,与前述做同样处理。 14 is determined in Step S34 described later when the same value or more, step S36 through step S3 in FIG. 2 enters, and do the same process as the above-mentioned ratio is not predetermined.

[0084] 图2的步骤Sll的手写输入文字笔迹的自动移动处理如图5所示,首先判断手写输入文字笔迹是否接触画面框4。 Step [0084] FIG. 2 Sll handwritten input character handwriting automatic scroll process shown in FIG. 5, first determines whether handwriting input handwritten characters 4 contacts the screen frame. 该判断直接利用上述图3的步骤S21的判断结果。 The determination result of the determination in step direct use of the above-described S21 of FIG. 3. 因此当由图3的步骤S21判断手写输入文字笔迹与画面框4相接触时,图5的步骤S41也判断手写输入文字笔迹与画面框4相接触且进入步骤S46,在画面框4内,将手写输入文字笔迹向与该手写输入文字笔迹接触的画面框4的边的相反侧移动的同时,将该手写输入文字笔迹以规定的比例(如70% )缩小。 Thus, when the step of FIG. 3 S21 determines handwriting input handwritten characters with the screen frame 4 is in contact, the steps of FIG. 5 S41 also determines the handwriting input handwritten characters with the screen frame 4 contacted and enters step S46, the inside of the screen frame 4, the handwriting input handwriting character input character handwriting the handwriting is in contact with the opposite side edges of the screen frame 4 while moving, the ratio (e.g. 70%) of the handwriting input handwritten characters with a predetermined reduction.

[0085] 另一方面,步骤S41 (图3的步骤S21)中判断手写输入文字笔迹没有与画面框4 相接触时,进行图5所示的手写输入文字笔迹的部首等的识别处理(步骤S^)。 [0085] On the other hand, in step S41 (FIG. 3 step S21) determines that the handwriting input handwritten characters not in contact with the screen frame 4, as shown in FIG. 5 for the handwriting input handwriting character recognition processing such radicals (step S ^). 步骤S42 所进行的识别处理与通常的文字识别处理不同,该识别处理的目的是为了让图1的手写输入文字笔迹部首等识别调整部38判断已输入的手写输入文字笔迹是否有很大可能性作为汉字的部首或者汉字的一部分进行使用。 Recognition processing step S42 is performed by the character recognition process is usually different, the object is to make the recognition process of FIG. 1 handwriting input handwriting input handwriting character recognition of handwritten characters and other radical adjusting unit 38 determines whether an input has a great possibility or a radical of the part used for Chinese characters. 上述通常的文字处理是指:将输入的手写输入文字笔迹(由该手写输入文字笔迹形成的识别用文字笔迹)与存储于手写输入文字识别用数据库11中的各文字的标准文字图形相比较、识别。 The normal word processing means: handwriting input from the input handwritten characters (input handwritten characters is formed by the handwriting recognition of handwritten characters) stored identification comparison with a standard character pattern of each character 11 database handwritten input characters, recognition.

[0086] 也就是说,即使已经输入的手写输入文字笔迹作为文字不能被识别,也作如下识别处理:将与存储于上述手写输入文字识别用数据库11中的各文字的标准文字图形的部分一致程度作为判断基准,判断该手写输入文字笔迹是否作为汉字部首存在,或者,即使不作为汉字部首存在,判断该文字笔迹是否作为汉字的一部分被使用,例如没有输入上述“梁”字下面的“木”时的文字笔迹。 [0086] That is, even when the handwritten input character has been input handwriting can not be recognized as a character, but also recognition processing as follows: the input character recognition to the stored handwritten character pattern is consistent with the standard portion of each character in the database 11 as a reference degree judgment, determines whether the handwriting input handwritten characters as Chinese radicals exists, or, if not present as Chinese radicals, determines whether the character stroke is used as part of the characters, for example, there is no input to the "beam" following the word when handwritten characters of "wood."

[0087] 在步骤S43中由上述步骤S42的识别处理结果判断为手写输入文字笔迹被作为部首等使用的可能性很大时,在步骤S44中,根据可能成为什么样的偏旁部首(左偏旁、右偏旁、字头、字底),将该手写输入文字笔迹向画面框4内的任一方向移动。 [0087] The result of the determination by the recognition process in step S42 is a handwriting input handwritten characters when in step S43 is the possibility of using a radical as a large etc., in step S44, according to what may be radical (left radical, right-radical, prefix, word bottom), the handwriting input handwritten characters move in either direction in the screen frame 4. 例如,如果手写输入文字笔迹作为左偏旁使用的概率高时,使手写文字输入笔迹向画面框4内的左方移动; 如果手写输入文字笔迹作为右偏旁使用的概率高时,使手写文字输入笔迹向画面框4内的右方移动;如果手写输入文字笔迹作为字头使用的概率高时,使手写文字输入笔迹向画面框4内的上方移动;如果手写输入文字笔迹作为字底使用的概率高时,使手写文字输入笔迹向画面框4内的下方移动。 For example, if the handwriting input as handwritten characters using a high probability radical left the handwriting input handwritten character moves to the left in the screen frame 4; if handwriting input handwritten characters as a high probability of the right to use the radical, so that handwritten character input handwriting moved to the right in the screen frame 4; if handwriting input handwritten characters as a prefix used in a high probability of the handwritten character input handwriting 4 is moved upward in the screen frame; if the handwriting input as handwritten characters using a high probability that word at the end when the handwriting input handwritten character is moved downward in the screen frame 4.

[0088] 同样的,在步骤S42中检出手写输入文字笔迹是汉字的一部分(非部首)时,剪除该手写输入文字笔迹作为汉字的上、下、左、右哪一部分使用的可能性高,且根据检测的结果将手写输入文字笔迹在画面框4内移动。 [0088] Similarly, the handwriting input handwritten characters detected in step S42 is a part of the characters (non-radical), to cut off the input handwritten characters as handwritten characters, down, left, and right is a high possibility of use which part , and according to the result of detection handwriting input handwritten characters move within the screen frame 4. 因此,在上述“梁”字被输入中途还没有输入下方的“木”字的状态下,该已输入的手写输入文字笔迹虽不能被作为部首进行识别,却被检出作为汉字的一部分位于汉字上方的的可能性很高,从而能够使该手写输入文字笔迹自动向上方移动。 Under Therefore, in the "beam" word has not been entered is entered halfway below the "wood" status word, which has entered though the handwriting input handwritten characters can be recognized as a radical, but was detected as part of characters located above the possibility of characters is high, thereby enabling the handwriting input handwritten characters automatically move upward.

[0089] 另外,在步骤S44中,使输入到中途的手写输入文字笔迹在画面框4中移动的同时,最好能够考虑确保之后的输入空间(添笔空间),将该手写输入文字笔迹按规定尺寸进行缩小处理。 [0089] Further, in step S44, the input to the handwriting input handwritten characters halfway while the moving picture frame 4, it is best to consider the input space (the space Tim pen) to ensure that after, the handwriting input handwritten characters according to a predetermined size reduction processing.

[0090] 由步骤S43判断手写输入文字笔迹不能作为汉字的部首或者汉字的一部分被识别时,进入步骤S47,判断该手写输入文字笔迹不能进行自动移动处理,然后进入步骤S45,进行图2步骤S5以后的处理。 [0090] When judged at step S43 is not part of the handwritten input character is recognized as handwriting characters or kanji radical, the process proceeds step S47, the handwriting input handwritten characters is determined that the automatic scroll process can not be performed, then proceeds to step S45, the steps performed in FIG. 2 S5 subsequent processing.

[0091] 并且,由上述步骤S46、步骤S44进行了手写输入文字笔迹的缩小移动处理后,也进入步骤S45,进行图2的步骤S5之后的处理。 [0091] Further, the above step S46, the step S44 is performed after the process moves to step S5 reduction treatment, but also into the step S45, the handwriting input performed in FIG. 2 handwritten characters.

[0092] 图2的步骤S13中的输入文字不能识别时的处理如图6所示。 [0092] The processing time of the input character as shown in step S13 of FIG. 2 in FIG. 6 does not recognize. 最初,显示如下指示:由于手写输入文字识别用数据库11中不存在与手写输入文字笔迹相对应的文字,请再次输入(步骤S51)。 Initially, the display as indicated: because handwriting character recognition of handwritten characters and handwriting input text corresponding to the absence of a database 11, enter (step S51) again. 之后,步骤S51的指示显示结束后,判断是否经过了规定时间(例如4秒),判断为没有经过规定时间时,进入步骤S53,判断使用者是否进行了返回手写输入的指示操作。 Thereafter, the display indicates the end of step S51, it is determined whether a predetermined time (e.g. 4 seconds), determines that the predetermined time has not elapsed, into the step S53, the user determines whether a handwriting input return instructions.

[0093] 反之,如果步骤S52中判断经过了规定时间时,如图所示进入步骤S57,消去之前输入的手写输入文字笔迹,通过步骤S58返回图2的步骤Si,进行新的手写输入处理。 When [0093] Conversely, if in step S52 the predetermined time has elapsed is determined, as shown in FIG enter step S57, before erasing handwriting input handwriting text input, the step returns step S58 of FIG. 2 Si, a new handwriting input process. 步骤S53中使用者进行了返回手写输入的指示操作时进入步骤S57,消去手写输入文字图形,通过步骤S58返回图2的步骤Sl进行新的手写输入处理。 Step S53, the user performs the instruction operation enters the return handwriting step S57, erasing handwriting character pattern, a new handwriting input process returns to step Sl of FIG. 2 in step S58.

[0094] 并且,当由步骤S53判断使用者没有进行返回手写输入的指示操作时,进入步骤S54判断使用者是否进行了变更文字输入方法的指示操作,如果判断没有进行变更输入方法的操作指示时,通过步骤S59判断使用者是否进行进一步的手写输入(添笔)操作。 [0094] Then, when the user is determined by the step returns no indication of the handwriting input operation S53, proceeds to step S54 judges whether or not the user to change the text input method of the instructions, if judged that no changing operation instruction input method , the step S59 determines whether the user further handwriting input (pen Tim) operation.

[0095] 这里如果判断使用者进行了进一步的手写输入时,即在步骤S51的指示显示后的规定时间内使用者没有进行返回手写输入的指示,且使用者也没有指示变更文字输入方法,在此状态下使用者进行了更进一步的手写输入时,由于意味着继续进行手写输入,因此返回图2的步骤S2,对手写输入文字笔迹反复进行检出输入空间不足处理之后的动作。 [0095] Here, if the user performs a determination is further handwriting input, i.e., the user does not return a handwriting input instruction within a predetermined time after the indicator is displayed at step S51, and the user can change the text entry method is not instructed, in in this state when the user performs handwriting input further, since the handwriting input means continuing, the flow returns to step S2 of FIG. 2, handwritten characters on a handwriting input operation is repeated after the detection of insufficient input spatial processing. 另外,如果步骤S59中判断使用者没有进行更进一步的手写输入时,返回步骤S52,在经过规定时间之前反复进行步骤S53以后的处理。 Further, if the user is determined in step S59 no further handwriting input, return to step S52, S53 subsequent processing step performed before the elapse of the predetermined time repeatedly.
