Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a font creation method and apparatus, and a storage medium.
[0002]
[Prior art]
When creating a new font, it is necessary to unify the keynote of each character. Therefore, conventionally, it is necessary to create several font samples, and the designer must manually create and register characters for each character based on the font samples. However, unlike Western characters such as alphabets, there are a lot of characters that need to be created in the case of characters in the Kanji culture area such as Japanese, Korean, and Chinese. Not only is it labor intensive, it is also difficult to create a uniform character font throughout. Moreover, there is a problem that it takes time to input data.
[0003]
Therefore, as a technique for automatically creating a font in order to reduce labor, conventionally, a “character font creation device” disclosed in Japanese Patent Laid-Open No. 63-184788 and an “external character font creation device” disclosed in Japanese Patent Laid-Open No. 5-66758 are known. was there.
[0004]
[Problems to be solved by the invention]
However, such a conventional automatic font generation system has the following problems. The former character font creation device simply disassembles characters into parts and combines them. To synthesize all characters, select and specify the font to be used from among the already registered fonts, The user still needs to give instructions for each character, such as an instruction to extract a portion to be used from the selected font, and there still remains a problem that it takes time to create the font.
[0005]
The latter external character font creation device is a support device when a user registers a new character as an external character in a device in which font data for basic characters has already been input. A user designates a necessary character from the font, and designates and extracts a necessary part in each part constituting the designated character, which is used for external character creation.
[0006]
At this time, it also has a function of deforming the parts by scaling the extracted parts. That is, this external character font creation apparatus is not an apparatus for creating a new font intended by the present invention, and therefore does not trigger the present invention. In addition, since it is necessary for the user to give an instruction to select a registered font necessary for creating a new external character (font), there is a problem similar to the former invention described above.
[0007]
The present invention has been made in view of the above-described background, and the object of the present invention is to solve the above-described problems, reduce the number of characters to be input, and create a unified character font. Another object of the present invention is to provide a font creation method and apparatus, and a storage medium that are easy to work.
[0008]
[Means for Solving the Problems]
In order to achieve the above-described object, in the font creation device according to the present invention, a character input means for inputting handwritten character data, a character set storage means for storing a character set necessary for synthesizing characters, and the character A part mainly composed of bias, wrinkles, etc. constituting the character is cut out from handwritten character data for each character constituting the character set stored in the character set storage means inputted by the input means, and the part Character cutout means for storing the character in the character parts storage means, character composition rule storage means for storing rules for forming characters from the parts, and the character parts storage means in accordance with the rules stored in the character composition rule storage means Character synthesis means for reading out and synthesizing the parts stored in the file to create a character font; Among the characters registered in the character storage means, a non-input character detection means for searching for a character that has not been handwritten input via the character input means, and a non-input character detected by the non-input character detection means on the display Character input instruction means for outputting and prompting handwriting input is provided.
[0009]
The recording medium according to the present invention receives handwritten character data of characters constituting a character set necessary for synthesizing characters, and includes parts mainly composed of bias, wrinkles, etc. constituting the characters from the handwritten character data. Processing to cut out, processing to store the cut-out parts in the character parts storage means, processing to read and synthesize the parts stored in the character parts storage means, create a character font, and characters necessary to synthesize the characters Among the characters registered in the character set storage means storing the set, the uninput character detection process for searching for characters that are not input by handwriting, and the uninput characters detected by executing this uninput character detection process are A computer storing a font creation program including instructions for causing a computer to execute a process for instructing a character to be input It was stored in a state capable of taking seen.
[0010]
On the other hand, the font creation method according to the present invention comprises character set storage means for storing a character set necessary for synthesizing characters, and handwritten character data of characters constituting the character set given through the character input means A font creation method in a font creation device for creating font data based on the above, receiving handwritten character data of characters constituting the given character set, and making up the character from the handwritten character data A step of cutting out a part mainly composed of the step, a step of storing the cut-out part in the character part storage means, and a part necessary for creating a new character is read from the character part storage means and synthesized. Creating a character font for the new character and registering it in the character set storage means Among the received characters, a non-input character detection step for searching for a character that has not been input by handwriting via the character input means, and a display of the non-input character detected by executing this non-input character detection step on the display The character input instruction step for prompting handwriting input is executed.
[0011]
For example, in the case of Japanese, Korean (Hangul characters), Chinese and other Chinese characters, characters are composed of a combination of several parts such as bias and 旁. Such parts are often used in common by a plurality of characters. Therefore, a part cut out and extracted based on a certain character can be used as a part for creating a font of another character. In other words, font data of another character can be created by selecting predetermined parts extracted from each character constituting the character set and combining them together. Then, the font data of such another character formed in this manner is unified with the characters constituting the character set. Therefore, it is possible to create a large number of character fonts with a uniform character tone by creating and inputting font data for a small number of characters (characters constituting a character set). In addition, the smaller the number of characters used as a basis, the easier it is to take a keynote between characters, and the integration of all characters can be achieved. For the user, the number of characters to be input is small.
[0012]
And, since the characters that make up the character set are detected as non-input characters and the detected non-input characters are designated as characters to be input next, the user sequentially inputs necessary characters according to the instructions. do it. Therefore, a new font can be automatically generated efficiently in a short time.
[0013]
In the embodiment, the non-input character is detected based on the information (flag and subsequent input character information) stored in the minimum character set database as the character set storage means. The apparatus 2 executes. Similarly, the instruction of the character to be input is realized by displaying on the display 5 via the character input instruction device 4 in the embodiment.
[0014]
The character set is a set of characters necessary and sufficient to obtain all the parts required for synthesizing / creating characters that ultimately require creation of font data. In the embodiment, it is possible to input the most efficiently if it corresponds to the minimum character set and the number of components is minimum. However, in the present invention, it is not always necessary to use the minimum combination / set. In other words, even if it is not the minimum, it is not necessary to input fonts of all the characters that are finally required by using parts created with other characters having the same parts, and workability is improved. However, it is preferable that the number of character sets is smaller because unnecessary input work is further reduced. In that respect, it is best to construct a minimum character set.
[0015]
As the character input device, for example, a device such as a tablet that can understand input information in real time and can also acquire information such as a document order, or a device that acquires pattern information without information such as a document order such as a scanner may be used. . The present invention is not limited to characters in the Kanji cultural area, and can be effectively applied to characters that use the same parts in common with different characters such as Arabic.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a first embodiment of a font creation apparatus according to the present invention. The automatic character composition / creation of this form is a new font created by storing preliminaries, wrinkles, etc. constituting the characters (kanji) in advance in the character parts database and combining them according to the characters to be created. I will make. At this time, by determining the minimum character set in advance, it is possible to synthesize and create a desired character simply by inputting the characters that make up the character set, thereby reducing unnecessary input work. I have to.
[0017]
That is, in the present embodiment, a font is created based on handwritten input data. As shown in the figure, information relating to characters (hereinafter referred to as “character data”) given from the character input device 1 is not yet stored. This is given to the input character detection device 2. The character input device 1 includes a tablet or the like for inputting handwritten characters.
[0018]
The non-input character detection device 2 searches for characters that are not input by the user from among the characters registered in the minimum character set database 3 and outputs and displays the non-input characters on the display 5 via the character input instruction device 4. However, the input is prompted (the role of the character input instruction device 4 is to actually prompt the input). Further, the input character data is transferred to the next character extraction and classification device 6.
[0019]
In accordance with the character cutout rules stored in the minimum character set database 3, the character cutout classification device 6 disassembles the characters input by the user into preset parts such as bias and wrinkles, and converts the classified parts into characters. It is stored in the parts database 9. The character parts are decomposed based on the character part data that can be extracted from the characters stored in the minimum character set database 3.
[0020]
Then, the character synthesizer 7 set in the next stage of the character cutout classification device 6 acquires predetermined parts stored in the character parts database 9 according to the rules stored in the character synthesis rule database 10, and those Is combined with each character part in accordance with the rules to synthesize new characters. Further, the new character font synthesized in this way is stored in the synthesized font database 8.
[0021]
Next, more detailed functions of each device will be described in accordance with an actual processing procedure. First, prior to describing each function, each database 3, 8, 9, 10 will be described. The minimum character set database 3 stores a minimum configuration of a character set including parts necessary for synthesizing all characters. Here, the minimum character set will be explained. For example, as in the column A in FIG. 2, it is assumed that three characters “Kang, dwell, and sex” are registered as the minimum character set. And if these three characters are disassembled into partial and flaws, they can be disassembled into six parts as shown in column B.
[0022]
Then, by combining these six parts as appropriate or using them alone, as shown in column C in the same figure, create the seven characters “Engineer, Lord, Raw, Jiang, Residential, Sexual, Note”. Can do. Since the seven characters are created based on the above-described three character fonts, the seven character fonts can be formed in a unified tone by simply unifying the design of the three fonts. In this way, by constructing characters based on combinations defined in advance, as shown in the column C, it is possible to automatically create more characters than the input characters.
[0023]
In other words, in the case of kanji, when parts other than radicals or radicals, such as bias, 旁, and crown, are divided into parts, there are many characters that are common to the parts. Therefore, when a certain character is created, a new character can be created by extracting and combining the parts from a plurality of characters having a common part. Then, by selecting characters with parts to be combined as appropriate (selecting a character with a large number of characters that can be created), a large number of characters can be synthesized and created based on a small number of characters. .
[0024]
In other words, a large number of character fonts can be automatically created by inputting a character font for such a base character. And, by selecting the number of characters to be based on less, there is no need for the user to input, and when the number of characters to be input is so small, the uniformity of the entire character is reduced. It becomes easy to plan. Therefore, the base character for creating such a large number of characters is registered in advance in the minimum character set database 3 as a minimum character set.
[0025]
And in the example of illustration shown above, although the example which synthesize | combined seven characters from three characters is shown, if the component which arises from the minimum character set data similarly is used, all characters will be expressed by few character inputs. Can do.
[0026]
In accordance with the principle described above, the actual data structure of the minimum character set database 3 is as shown in FIG. That is, each character constituting the minimum character, character part information that can be extracted from the character, an input confirmation flag indicating whether or not the character has been input, and a cut-out rule for cutting out the part from the input character are associated with each other To store.
[0027]
Thereby, the character (minimum character set) to be input by the user can be known. The initial value of the input confirmation flag stored in the flag area for determining whether or not each character constituting the minimum character set is input is “0”, and changes to “1” when a character is input (registered). I am doing so.
[0028]
The cut-out rule stores a rule for cutting out each part from a corresponding character when it is input, and is managed by a stroke when inputting the character. That is, in this embodiment, since a tablet is used as the character input device 1, information such as writing pressure and writing order can be acquired together with character input. Therefore, a part input with a single stroke is considered as one stroke, and information on what number stroke to what number stroke is stored for each part to be extracted.
[0029]
As an example, as shown in FIG. 4, in the case of “E”, first the partial “Sansui” is written and then the “work” part is written, so one part (from the first stroke to the third stroke) Knowledge / rules such as extracting from the fourth stroke to the sixth stroke as one part (work) are stored. Such cut-out rules are set and registered for each character constituting the minimum character set. Furthermore, information relating to the part number of each part is also associated and registered. That is, by providing information such as what part number is extracted from which part of which character, the extracted part information is managed and used by the part number. This part number is associated with the part number of the text part registered in the text part database.
[0030]
In the database shown in FIG. 3, each character or the like constituting the minimum character set is described with a specific character so that it can be easily understood visually. . For the part information, for example, a part number described later may be registered. The same applies to each database described later.
[0031]
On the other hand, the character parts database 9 pays attention to some parts constituting the character as in the data structure shown in FIG. 5, and registers the parts and the character information and part numbers that can be synthesized by the parts in association with each other. In addition, font (pattern) data of each part obtained by cutting out from character data input by handwriting by the character cutout classification device 6 is also stored. In order to facilitate the search for the presence / absence of input of font data, an area for setting a registration flag is also secured. This registration flag has an initial value of “0” and changes to “1” when the font data of the character part is registered.
[0032]
Furthermore, the character synthesis rule database 10 is a database in which synthesis rules for each character necessary for synthesizing fonts from character parts are stored. The combination target character, the part number to be used, and information for specifying the position when the part to be used is combined are registered in association with each other.
[0033]
Conceptually, for example, as shown in FIG. 6, the letter “E” represents the part number n (actual n is a fixed value attached to the part) in coordinates (0, 0). ), (80, 0), (80, 180), (20, 256), (0, 256), and is inserted into an area (the area constituting one character is set to 256 × 256), An area (one character is composed) of a part (work) of part number 1 divided by coordinates (80,0), (256,0), (256,256), (20,256), (80,180) The area to be set is 256 × 256) and can be synthesized. In this way, a table (not shown) that associates the part number to be used with information (coordinate values in the example shown) for specifying the area to be fitted is created and registered for all characters to be synthesized.
[0034]
Further, the synthesized font database 8 stores font data synthesized by the character synthesizer 7. For example, as shown in FIG. 7, the character to be registered (actually character code data) and the synthesized font are stored. The data structure is such that data (for example, bitmap) and a flag indicating whether or not the character has already been synthesized and registered are associated and stored. This flag also has an initial value of “0”, for example, and is set to “1” when font data is registered.
[0035]
Next, functions of each processing apparatus will be described. The non-input character detection device 2 has a function of executing the flow shown in FIG. That is, first, the minimum character set database 3 is accessed, and the minimum character set data stored therein is read (ST11). Then, by referring to the input confirmation flag attached to each character, a character that has not been input is selected.
[0036]
Next, the input confirmation flag area attached to each character is searched to search for a character with no flag, that is, an uninput character (ST12, ST13). If the flag itself does not exist or all the characters are flagged (input completion), the process is terminated. If there is a character for which no flag is set, the character is listed (ST14), and the character is registered in the uninput character detection buffer (ST15). The characters stored in the non-input character detection buffer are displayed on the display 5 via the character input instruction device 4 as will be described later.
[0037]
The above-described flowchart shows the basic (main) function of the non-input character detection device 2, but in this embodiment, the character data given through the character input device 1 is further received, and the received character data is The data is sent to the character segmentation device 6 as it is, and an input confirmation flag for the received character is set (1 is written).
[0038]
The character input instructing device 4 has a function of acquiring a non-input character stored in the above-described non-input character detection buffer and instructing the display 5 as a character to be input next to the user. Have. The non-input character detection buffer can be mounted in the non-input character detection device 2, the character input instruction device 4, or as another configuration.
[0039]
The function of the character cutout classification device 6 is as shown in the flowchart of FIG. That is, first, as described above, the non-input character detection device 2 detects a non-input character among the characters constituting the minimum character set and is prompted to provide handwritten character data. The character data input through the non-input character detection device 2 is received (ST21).
[0040]
Since the received character data is a character that was prompted to be input by the character input instruction device 4 before that, it can be understood what character data the character data is. Therefore, the minimum character set database 3 is accessed and the character extraction rule for processing is read (ST22). Then, parts are cut out from the given character data (bitmap data) according to the read out cutting rules (ST23). Next, the cut out parts are registered at the corresponding positions in the character parts database 9 (ST24). Further, when this part (font data) is registered, the unregistered flag in the character parts database 6 is also set to “1”.
[0041]
The character synthesizer 7 functions as in the flowchart shown in FIG. That is, first, the synthesized font database 8 is accessed to detect unsynthesized characters (ST31, 32). In this embodiment, a flag area provided in the composite font database 8 is searched, and a character with a flag “0” is detected as an unsynthesized character.
[0042]
The following processing is sequentially performed for all such unsynthesized characters (composition target characters). That is, the character synthesis rule database 10 is referred to read a character synthesis rule necessary for creating an unsynthesized character (composition target character) to be processed (ST33). Thus, since the part number to be used is known, the character part database 9 is accessed using the part number as a key, and the font data for the corresponding part is read (ST34).
[0043]
Then, the part parts read in step 34 are combined based on the character synthesis rule read in step 33, and a synthesis target character is automatically created (ST35). The created font data is registered in the composite font database 8. Thereby, all the handwritten characters finally synthesized are stored in the synthesized font database 8 as one font.
[0044]
Next, an overall processing flow (character font creation method) using the apparatus of the above-described embodiment will be described. First, the entire process is executed according to the flowchart shown in FIG. That is, first, the minimum character set database 3 is accessed, and the data in the character parts database 6 is sent to the non-input detection device 2. Based on this, the non-input detection device 2 executes the flowchart shown in FIG. 8 and registers the non-input characters in the non-input character detection buffer (ST41).
[0045]
When data (characters constituting an unregistered minimum character set) exists in this non-input character detection buffer, the character input instruction device 4 is operated to display the next character to be input on the display 5 for input. (ST42, 43).
[0046]
In response to this input instruction, the user inputs handwritten characters using the character input device 1 (tablet). Therefore, the character data being input is acquired, and the trajectory of each stroke is acquired as bitmap data (ST44). Of course, with this acquisition, the above-described functions of the non-input character detection device 2 such as setting an input confirmation flag in the minimum character set database 3 are executed.
[0047]
Next, clipping is performed based on the acquired bitmap data of the characters, and each component (part) is disassembled. That is, the bitmap data is sent to the character cutout classification device 6 where the flowchart shown in FIG. 9 is executed. As a result, the parts extracted by decomposition are registered in the character parts database 9.
[0048]
Next, the character synthesizing device 7 is operated to read the character synthesis rule of the unsynthesized character to be synthesized, create a character that can be created by combining already registered parts (ST46), and the synthesized result is used as the synthesized font database 8 (ST47). Then, by executing the above process in sequence and registering all the characters constituting the minimum character set, it is possible to create all handwritten characters for all the characters to be configured, and using them as one font, It is stored in the composite font database 8.
[0049]
In the above-described embodiment, an example of the flow of processing has been shown, but the actual operation timing of each device is not limited to that shown in FIG. That is, for example, the devices 2, 6, and 7 may be operated independently and in parallel. That is, for example, the non-input character detection device 2 and the character segmentation device 6 operate according to a series of steps (steps 41 to 45 in FIG. 11), extract parts from each character of the minimum character set, and perform a character synthesis device. 7 may be operated (ST46, 47), and characters that can be created from registered parts may be combined in order and synthesized (created). First, steps 41 to 45 are repeatedly executed. Various changes can be made such as inputting characters constituting all the minimum character sets, extracting each part, and then operating the character synthesizer 7 to create all characters at once.
[0050]
Further, as for the character input instruction, as in the above-described embodiment, the non-input character detection device 2 requests registration of the non-input character based on the flag in the minimum character set database 3. Is not limited to this. For example, when the character synthesizer 7 tries to read a necessary character part by accessing the character part database 9 in order to create a character to be synthesized, the part is still unregistered. The user may be prompted to input necessary characters directly or via the non-input character detection device 2 or the like, and various modifications can be made.
[0051]
Furthermore, a request for a character to be input next to be displayed on the display 5 via the character input instruction device 4 may simply display only the character. For example, as shown in FIG. The characters synthesized by the above may be displayed together. In the example of FIG. 12, a plurality of characters from the minimum character set are written together. In such a case, for example, if the rule is to input in order from the leftmost character, the above-described embodiment is used as it is. Can be applied. In addition, if the user can select and input any character from the multiple characters written together, add a numeric keypad, mouse or other device to register which character is selected in the input device. Yes.
[0052]
FIGS. 13-15 has shown the principal part of the 2nd Embodiment of this invention. That is, in the first embodiment described above, since a tablet is used as the input device 1 and character data input in real time can be acquired, parts can be extracted using strokes. It was. On the other hand, the present embodiment is an apparatus for creating a composite character based on character data having no order information input separately.
[0053]
The configuration of the entire apparatus can be the same as that of the first embodiment shown in FIG. To explain the difference, a scanner is used as the character input device 1. Further, as a cut-out rule stored in the minimum character set database 3, an area where each part exists is set as shown in FIG. 13, and each area is associated with a part number. In the illustrated example, in the case of the character “E”, the left area defined by (0,0), (65,0), (55,256), (0,256) cuts out the part “Sanzui”. An area on the right side defined by (65, 0), (256, 0), (256, 256), and (55, 256) is an area for cutting out a part called “work”. Similarly, in the case of the character “Zhi”, the upper area partitioned by the line connecting (0, 110) and (256, 110) is the area for cutting out the part “shi”, and the lower area is “heart”. This is the area where parts are cut out.
[0054]
Further, the character cutout classification device 6 basically acquires cutout rules stored in the minimum character set database for each character constituting the minimum character set received in the same manner as in the first embodiment. The individual parts are extracted according to the acquired cut-out rules. At this time, as shown in FIG. 14, if there is a deviation between the received character data (bitmap) and the extraction rule area, the position is shifted, and if the sizes do not match, enlargement / reduction, etc. It has a fine adjustment function of the cut-out position such as normalization.
[0055]
The character cut-out process using this scanner is as shown in the flowchart of FIG. In the figure, step 51 is executed using the input device 1, and the character code determination process of step 52 specifies the character code of the input character. For example, as in the first embodiment, character input is performed. The character instructed to input by the instruction device 4 can be specified as the input character. Also, instead of waiting for an input instruction in this way, if the user inputs sequentially (scanner reading), the contents of characters entered using the OCR function can be specified and used. Various measures can be taken, such as a specific code data being entered by a person.
[0056]
Step 53 and subsequent steps are functions of the character cutout classification device 6. More specifically, acquiring the character data obtained by reading the character data performed in step 51 is one of the functions of the character cutout classification device 6. As is apparent from a comparison of this figure with FIG. 9, a fine adjustment function of the cutout position in step 54 is added.
The other database functions are the same as those in the first embodiment, and a detailed description thereof will be omitted.
[0057]
In each of the above-described embodiments, the character to be synthesized has been described with reference to Japanese as an example, but the present invention is not limited to this and can be applied to other foreign languages. As an example, taking Korean as an example, it is possible to disassemble into six parts as shown in column B just by inputting two characters as shown in column A in FIG. Then, by combining these six parts as appropriate or using them alone, 35 characters can be created as shown in FIG. Since the 35 characters are created based on the above-described two character fonts, the 35 character fonts can be formed in a unified tone by simply unifying the design of the two fonts. it can.
[0058]
Therefore, by creating a minimum character set, cutout rule, composition rule, etc. according to the Korean language, font data for all characters is automatically created from the registration of a small number of characters as in the above embodiments. be able to. Of course, it goes without saying that it can be applied to other languages regardless of Korean.
[0059]
Each of the above-described embodiments has been described on the assumption that it is incorporated in the apparatus, but it is a program for causing a computer to execute each of the above-described processes (for example, a process for executing the flowchart shown in each figure). The program may be provided by being recorded on a predetermined recording medium.
[0060]
That is, as shown in FIGS. 18 and 19, the recording medium includes a floppy (registered trademark) disk (FD) 20 and a CD-ROM 21, and the program stored in the recording medium 20, 21 is an FD drive. 22 and the HD unit 25 connected (incorporated) to the computer 24 via the CD-ROM drive 23, whereby the computer 24 constitutes the apparatus described in the above embodiment. .
[0061]
Specifically, the non-input character detection device 2, the character segmentation classification device 6, the character synthesis device 7, the character input instruction device 4 and the like in the embodiment are installed in the HD unit 25. For example, the HD unit 25 is used every time it is used. To the internal memory 26, where various processes can be performed at high speed. The minimum character set database 3, the character parts database 9, the character synthesis rule database 10, and the synthesized font database 8 are realized by the HD unit 25 or the like.
[0062]
Furthermore, the tablet 30 comprises the character input device 1 in the state incorporated in the computer. Further, when inputting code data or the like, the keyboard 27 and the mouse 28 are used. Each character data constituting the minimum character set is sequentially input using these input devices, and a character font is created based on the input character data.
[0063]
【The invention's effect】
As described above, in the font creation method and apparatus and the storage medium according to the present invention, when font data for “a certain character” is input, other characters that use the parts cut out and extracted from the font data are related. Since it can be created using parts extracted from "a certain character", a part of the characters (character set is composed without creating, entering and registering the font directly for all the finally required characters. Font data for all characters can be created simply by creating and inputting a font for the character to be used.
[0064]
Therefore, it is possible to reduce the number of characters to be input, the input work itself is simplified, and further, it is only necessary to perform the work for unifying the basic character of the characters between the characters, so that the creation of the font for each character becomes easy. .
[0065]
Furthermore, since the character to be input is instructed, it is only necessary to input the font data of the character in accordance with the instruction, and the input operation can be performed efficiently.
