Abstract

PURPOSE:To realize the reduction of a font data amount without lowering a degree of freedom in expressing a character pattern and to contrive an effective use of a conventionally existing font technique. CONSTITUTION:A font ROM 2 stores standard main part data and character pattern data. The former is formed by expressing standard shapes of main parts of basic elements of a plurality of kinds for expressing a set of character patterns by one Bezier curve and line width values. The latter contains control information for decomposing each character of a character set to basic elements and specifying the shape of the main part of the basic element of the standard shape and information representing a difference from the standard shape. At the time of generation of a character pattern, a CPU 1 corrects a profile line shape of a main part of a basic element represented by the standard main part data stored in the font ROM 2 on the basis of the character pattern data stored in the font ROM 2, thereby restoring a profile line shape of a main part of a basic element of a required character pattern. The restored shape is developed in a character pattern developing memory 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high quality character pattern generating method and a high quality character output device for obtaining high quality characters having smooth contour lines.

[0002]

2. Description of the Related Art In recent years, word processors or computer devices generally use so-called outline fonts as a means for improving the quality of print output and display output. The outline font draws the shape of the outline of a character pattern with a single stroke and fills the inside of the outline font.The font data that describes the outline shape is such that the outline is composed of multiple straight lines or curves. The data structure is expressed in the state of being divided into segments, and these segments are arranged in the order of writing with one stroke.

By the way, a character is composed of a combination of lines called strokes drawn by a brush or the like. Since each stroke itself is a straight line or a curved line whose line width is constant or whose line width changes sequentially, The shapes of the respective contour lines forming the two sides of are substantially similar. Therefore, in the outline font, if it is possible to reduce the amount of data by expressing the shape of each contour line forming both sides of the stroke with the same data, in reality, the outline font is a character pattern. Since it is a data structure that sequentially describes the contour shape of the stroke with a single stroke, it was necessary to express the shapes on both sides of the stroke as independent data. Therefore, there is a situation in which the redundancy of font data increases, which is one of the causes for increasing the data amount of font data.

On the other hand, in the past, for example, Japanese Patent Publication No.
No. 52475, the character pattern is decomposed into a plurality of strokes, and each stroke is described as stroke data consisting of position information of a plurality of representative points and the stroke thickness information group at each of the representative points. At the same time, a font technology has been considered in which these stroke data are combined and drawn to generate a character pattern. With this, the redundancy as described above becomes small, so that the amount of data can be reduced. become.

[0005]

However, in the prior art in which the data amount is reduced as described above, a plurality of strokes forming each character are described for each character pattern for one typeface. Since stroke data is required, an extremely large amount of stroke data is required for each typeface, and the structure of the stroke data cannot be simplified so much, which reduces the amount of data. There was a problem that it was not fully utilized.

Further, in the above-mentioned conventional technique, the entire stroke (and thus the entire character) is unified and described in the form of the combination of the position information and the thickness information of the representative point of the stroke. In actually drawing a character pattern, it is difficult to freely express a wide variety of character patterns such as an outline font, and this is a great impediment. Also, since the large amount of outline font data already provided cannot be used, new font data must be created for all character patterns, which results in a waste of work. Currently, peripheral technologies (outline drawing, filling technology, etc.) for using outline fonts are accumulated, but it is also necessary to develop technology corresponding to this, and for this reason,
When it was put to practical use, there were great difficulties such as a rise in development costs.

The present invention has been made in view of the above circumstances and the fact that the number of types of basic elements constituting a group of character patterns including Chinese characters is limited to a fixed number, and its purpose is to set fonts. A large reduction in the amount of data can be achieved without lowering the degree of freedom in the expression of character patterns, and the existing font technology can be effectively used to reduce development costs. It is to provide a method for generating a high quality character pattern, and to output such a high quality character that can reduce the amount of data with a rational configuration and reduce the hardware cost. To provide a device.

[0008]

In order to achieve the above-mentioned object, a method for generating a high quality character pattern according to the present invention includes at least one of a plurality of types of basic elements constituting a group of character patterns including Chinese characters. A standard size is set for the parts, and the shape of the core line that passes through the middle of each contour line for each of the basic elements of the standard size Is described as standard main body data consisting of a combination of reference data indicating the above and a sample value indicating the width of the main body corresponding to the core line, while at least a part of the characters in the character pattern group is decomposed into respective basic elements. Then, the control data for identifying the basic element necessary to restore the character and the identified standard size basic element are used. Describes the combination of element data representing the difference between the placement as character pattern data,

In generating a character pattern from the character pattern data, when the contour line shapes on both sides of the main body of the basic element forming the character pattern are restored, the character is based on the control data in the character pattern data. A basic element required to form the basic element data that describes the basic element specified in this way is corrected based on the element data in the character pattern data that describes the basic element. Thus, the contour line shapes on both sides of the main body portion of the designated basic element are obtained (claim 1).

In this case, the element data in the character pattern data is converted into coordinate data indicating the shape of a core line passing through the center of the main body of the basic element, the width of the main body and the sample value in the standard main body data. It can also be expressed by including a difference sample value indicating a difference from the width of the standard main body shown (claim 2).

Further, when such a data representation method is adopted, when the contour line shapes on both sides of the main body of the basic element are restored in generating a character pattern, it is based on the control data in the character pattern data. Designate the basic elements required to form the character, and specify the standard core wire shape indicated by the reference data in the standard main body data corresponding to the specified basic element in the character pattern data. The shape of the core line of the specified element is restored by converting to the position indicated by the coordinate data of and the scaling is performed, and the sample value in the standard main body data corresponding to the specified basic element is set in the character pattern data. The width of the main body portion of the basic element may be restored by adding the difference sample values of .

Further, the element data in the character pattern data includes difference data relatively describing a difference between a core line passing through the center of the main body of the basic element and a core line restored by the scaling operation. In expressing, when restoring the contour line shape on both sides of the main body of the basic element in generating the character pattern, the shape of the core line restored by the scaling operation is based on the difference data in the character pattern data. You may make it correct (Claim 4).

Further, as a sample value indicating the width of the main body portion corresponding to the core line, the main body portion at each point of parameters t = 0, 1/3, 2/3, 1 in the cubic Bezier curve expressing the core line. It is also possible to use a value indicating the width of or the half of the width.

As a method of generating a high quality character pattern,
Instead of the method of using the shape of the core line passing through the middle of the contour line as the reference data as described above, the shape of the contour line itself may be used as the reference data.

That is, for this purpose, a standard size is set for at least a part of a plurality of types of basic elements constituting a group of character patterns including Chinese characters, and
For each of these standard size basic elements,
A standard main body part consisting of the contour line shapes on both sides of the main body part excluding at least both end portions, and a combination of reference data indicating the shape of one contour line and a sample value indicating the width of the main body part corresponding to the one contour line. While describing as data, at least some of the characters in the character pattern group are decomposed into basic elements, respectively, and control data for specifying the basic elements necessary to restore the characters, and the specification thereof. Described as character pattern data a combination with element data expressing the difference from the standard element of the standard size described above, and in generating a character pattern from the character pattern data, the main part of the basic element forming the character pattern When restoring the contour line shapes on both sides, based on the control data in the character pattern data, An element in the character pattern data in which the basic elements required to form the character are designated, and the standard main body data describing the designated basic element is described in the basic element, if necessary. The contour shapes on both sides of the main body portion of the designated basic element may be obtained by performing correction based on the data (claim 6).

In this case, the element data in the character pattern data includes coordinate data indicating the shape of one of the contour lines on both sides of the main body of the basic element, the width of the main body, and the standard main body data. It can also be expressed by including a difference sample value indicating a difference from the standard width of the main body indicated by the sample value inside (claim 7).

Further, when such a data representation method is adopted, when the contour shape on both sides of the main body of the basic element is restored in generating the character pattern, it is based on the control data in the character pattern data. Designate the basic elements required to form the character, and define the standard contour shape indicated by the reference data in the standard main body data corresponding to the designated basic element as described above in the character pattern data. The contour shape of one of the specified elements is restored by performing the operation of converting to the position indicated by the coordinate data in and changing the magnification, and the sample value in the standard main body data corresponding to the specified basic element is restored. The width of the main part of the basic element may be restored by adding the difference sample value in the character pattern data. According to claim 8).

Further, in the element data in the character pattern data, the difference between one of the contour lines on both sides of the main body of the basic element and the contour line restored by the scaling operation is relatively calculated. When the contour line shapes on both sides of the main body of the basic element are restored in generating the character pattern after expressing the difference data described, the shape of the contour line restored by the scaling operation is changed to the above character. The correction may be performed based on the difference data in the pattern data (claim 9).

Further, as a sample value indicating the width of the main body portion corresponding to one contour line, the parameter t = 0, 1/3, 2/3, in the cubic Bezier curve expressing the contour line,
A value indicating the width of the main body portion at each point 1 can be used (claim 10).

In the method for generating a high quality character pattern according to claim 1 or 6, at both end portions of the basic element, the outline shapes of the both end portions are described by an outline method having a plurality of coordinate point information. It is possible to adopt a configuration in which it is performed based on the detailed shape data formed (claim 11).

The high-quality character output device according to the present invention comprises storage means for storing font data and control means for drawing a character pattern based on the font data read from the storage means. The storage means sets a standard size for at least a part of a plurality of types of basic elements that form a group of character patterns including Chinese characters, and at least both ends of each of the standard size basic elements. Standard main body part data consisting of the contour line shapes on both sides of the main body part excluding the part, and the combination of reference data indicating the shape of the core line passing through the middle of each contour line and the sample value indicating the width of the main body part corresponding to the core line. The first storage area stored as, and at least a part of the characters of the character pattern group are decomposed into basic elements, respectively, A second combination storing control data for specifying a basic element required to restore a character and element data expressing a difference between the specified standard size basic element and character pattern data. While storing the character pattern data, when the control means restores the contour line shape on both sides of the main body of the basic element that constitutes the character pattern in generating the character pattern. The basic element data that specifies the basic element necessary to form the character based on the control data in the standard main body data that describes the specified basic element, and the character that describes the basic element as necessary. By performing correction based on the element data in the pattern data, the specified basic element It is obtained by a structure for drawing the main body portion on both sides of the outline shape (claim 1
2).

In this case, as the element data in the character pattern data stored in the first storage area of the storage means, coordinate data indicating the shape of a core line passing through the center of the main body of the basic element, and the main body And a difference sample value indicating a difference between the width of the standard main body part and the width of the standard main body part represented by the sample value in the standard main body part data can be used (claim 13).

Further, when the control means restores the contour line shapes on both sides of the main body of the basic element in generating the character pattern, it is necessary to compose the character based on the control data in the character pattern data. While specifying the basic element, the standard core shape indicated by the reference data in the standard main body data corresponding to the specified basic element is converted to the position indicated by the coordinate data in the character pattern data. The core line shape of the specified element is restored by performing the scaling operation by adding the difference sample value in the character pattern data to the sample value in the standard main body data corresponding to the specified basic element. The width of the main part of the element may be restored.

Further, the element data in the character pattern data stored in the first storage area of the storage means is a core line passing through the center of the main body of the basic element and a core line restored by the scaling operation. The difference is expressed by including the difference data relatively describing the difference, and the control means uses the scaling operation to restore the contour shapes on both sides of the main body of the basic element in generating the character pattern. The shape of the restored core wire may be corrected based on the difference data in the character pattern data (claim 15).

Further, as a sample value showing the width of the main body portion corresponding to the core line, the main body portion at each point of parameters t = 0, 1/3, 2/3, 1 in the cubic Bezier curve expressing the core line. It is also possible to use a value indicating the width of or a value of 1/2 of the width (claim 16).

As a high quality character output device having a storage means for storing font data and a control means for drawing a character pattern based on the font data read from the storage means, the contour as described above is used. Instead of storing the shape of the core line passing through the middle of the line as the reference data, the shape of the contour line itself may be stored as the reference data. That is, for this purpose, the storage means is set to a standard size for at least a part of a plurality of types of basic elements that form a group of character patterns including Chinese characters, and the standard size of these standard sizes is set. For each of the elements, a combination of the contour line shapes on both sides of the main body portion excluding at least both end portions, with reference data indicating the shape of one contour line and a sample value indicating the width of the main body portion corresponding to the one contour line. A first storage area stored as standard main body data and at least some characters of the character pattern group are decomposed into basic elements, and a basic element necessary for restoring the character is specified. Character pattern is used for the combination of control data for control and element data expressing the difference between the specified standard size basic element. And a second storage area stored as data, the control means restores the contour shapes on both sides of the main body of the basic element forming the character pattern when generating the character pattern. , Specifying the basic element required to form the character based on the control data in the character pattern data, and the standard main body data describing the specified basic element The contour line shapes on both sides of the main body portion of the designated basic element may be drawn by correcting based on the element data in the character pattern data describing the element (claim 17).

In this case, as the element data in the character pattern data stored in the first storage area of the storage means, coordinate data indicating the shape of one of the contour lines on both sides of the main body of the basic element. And a difference sample value indicating a difference between the width of the main body portion and the width of the standard main body portion indicated by the sample value in the standard main body portion data can be used. Item 1
8).

Further, the control means is required to compose the character based on the control data in the character pattern data when the contour shape on both sides of the main body of the basic element is restored in generating the character pattern. The basic contour shape indicated by the reference data in the standard main body data corresponding to the designated basic element is converted into the position indicated by the coordinate data in the character pattern data. Then, the shape of one contour line of the specified element is restored by performing the scaling operation, and the difference sample value in the character pattern data is added to the sample value in the standard main body data corresponding to the specified basic element. By doing so, the width of the main body of the basic element can be restored.

Further, the element data in the character pattern data stored in the first storage area of the storage means is converted into one of the contour lines on both sides of the main body of the basic element and the scaling operation. In the case where the control means restores the contour shapes on both sides of the main body portion of the basic element in generating the character pattern after expressing the difference including the difference with the contour line restored by In addition, the shape of the contour line restored by the scaling operation may be corrected based on the difference data in the character pattern data (claim 20).

Further, as a sample value indicating the width of the main body portion corresponding to one contour line, the parameters t = 0, 1/3, 2/3, in the cubic Bezier curve expressing the contour line,
A value indicating the width of the main body portion at each point 1 can be used (claim 21).

In the high-quality character output device according to the twelfth or seventeenth aspect, the contour line shapes of both end portions of the basic element are described in the storage means by an outline method including a plurality of coordinate point information. After storing the detailed shape data, the control means may be configured to draw the contour shape of both end portions of the basic element based on the detailed shape data (claim 2).

[0032]

In general, the types of basic elements that make up a group of character patterns including Chinese characters are limited to a fixed number, and therefore, standard data indicating a standard shape for each of these basic elements. In the case of actually generating a character pattern, each of the character patterns to be generated is corrected by correcting the necessary one of the standard basic element shapes shown by the standard data. The shape of the basic element can be obtained. The high quality character pattern generation method and the high quality character output device according to the present invention basically use such an idea.

According to the method for generating a high quality character pattern according to the first aspect, the standard main body data having a standard size for at least a part of a plurality of types of basic elements forming a group of character patterns is used. And at least some characters of the character pattern group are decomposed into the basic elements,
Describe as character pattern data the combination of the control data for specifying the basic element required to restore the character and the element data expressing the difference between the specified standard size basic element. Every time a character pattern is generated, the basic elements required to compose the character pattern are specified based on the control data, and the standard size of the specified basic element is described. By correcting the standard main body portion data based on the element data, the contour shapes on both sides of the main body portion of the designated basic element are restored.

In this case, the standard main body part data is described in the form of a main body part excluding both end parts, that is, a core wire shape and its line width, for each basic element of standard size. Concerning the part that is suitable for, describe the contour line shape on both sides of it by combining the reference data that shows the shape of the core line that passes through the middle of the contour line and the sample value that shows the width of the main part corresponding to that core line. Therefore, the amount of data can be relatively reduced, and the data in this part only needs to describe a relatively small number of basic elements that make up a character pattern, which is an enormous amount for one typeface. There is no need to describe characters, and the amount of data will be greatly reduced.

The character pattern data is described by a combination of control data for specifying the basic elements required to restore each character and element data expressing the characteristic points of those basic elements. Therefore, the character pattern data itself is much simpler than the normal outline font data, and the amount of the data is greatly reduced. In other words, for the main body of each basic element that constitutes a character, it can be generated based on the standard main body data and the character pattern data in which the amount of data is greatly reduced, and as a result, the entire font is generated. The amount of data can be reduced as compared with the conventional configuration.

According to the method for generating a high quality character pattern described in claim 2, the element data in the character pattern data includes coordinate data indicating the positions of two points, the width of the main body portion and the standard main body portion. Since the character pattern data is expressed as a difference sample value that indicates the difference from the standard width of the main body indicated by the sample value in the data, the character pattern data becomes relatively simple and the dynamic range of the difference sample value As a result, the data amount of the character pattern data can be reduced.

According to the method of generating a high quality character pattern described in claim 3, when the contour line shapes on both sides of the main body of the basic element are restored, the basic element specified by the control data in the character pattern data is restored. , The standard core line shape indicated by the reference data in the corresponding standard main body data is converted to the position indicated by the coordinate data in the character pattern data and scaled. The shape of the core of the basic element is restored, and the difference sample value in the character pattern data is added to the sample value in the standard main body data corresponding to the specified basic element. The width of the main part is restored. In this case, the relatively complicated operation required to restore the target basic element from the basic element indicated by the standard main body data is only the operation for coordinate conversion as described above. Since the width of the main body portion is restored only by simple addition without performing the calculation for the coordinate conversion, the amount of calculation at the time of restoring the basic element is reduced.

According to the method of generating a high quality character pattern described in claim 4, when the contour line shapes on both sides of the main body of the basic element are restored, the core line restored by the above-described scaling operation is restored. Since the shape is corrected based on the difference data in the character pattern data, the core line shape can be accurately restored.

As described in claim 5, as a sample value indicating the width of the main body portion corresponding to the core line, the parameter t = 0, 1 / in the cubic Bezier curve expressing the core line.
When the value indicating the width of the main body portion at each point of 3, 2/3, or 1 or the value of 1/2 of the width is used, the contour line shapes on both sides of the main body portion are approximated. Since the data indicating the control points of the cubic Bezier curve can be easily obtained, the standard main body data can be easily converted into the data for drawing the contour line.

According to the method for generating a high quality character pattern described in claim 6, the standard main body data is the outline shape of both sides of the main body excluding both end portions for each of the basic elements of standard size. Is described by a combination of reference data indicating the shape of one contour line and a sample value indicating the width of the main body portion corresponding to that contour line. The amount of data will be greatly reduced. Further, the character pattern data is greatly reduced as in the case of the first aspect, and as a result, the entire font data amount can be reduced as compared with the conventional configuration.

Also in the method for generating a high quality character pattern according to claim 7, the element data in the character pattern data includes coordinate data indicating the shape of a core line, the width of the main body portion, and the standard main body portion data. Since it is represented by the difference sample value indicating the difference from the standard width of the main body indicated by the sample value of, the character pattern data becomes relatively simple, and the dynamic range of the difference sample value is narrow. Therefore, the data amount of the character pattern data is reduced.

According to the method of generating a high quality character pattern described in claim 8, when the contour line shapes on both sides of the main body of the basic element are restored, the standard main body corresponding to the specified basic element is restored. The shape of the standard contour line indicated by the reference data in the partial data is converted to the position indicated by the coordinate data in the character pattern data and scaled, whereby one contour of the designated basic element The width of the main body of the specified basic element is restored by adding the difference sample value in the character pattern data to the sample value in the standard main body data corresponding to the specified basic element. Is restored, the calculation amount at the time of restoring the basic element is reduced as in the case of the third aspect.

According to the method of generating a high quality character pattern described in claim 9, when the contour line shapes on both sides of the main body of the basic element are restored, the contour line restored by the scaling operation as described above. Since the shape of is corrected based on the difference data in the character pattern data, the contour shape can be accurately restored.

As described in claim 10, as a sample value indicating the width of the main body portion corresponding to one contour line, the parameter t in the cubic Bezier curve expressing the contour line is described.
Also in the case where the configuration is such that a value indicating the width of the main body portion at each point of = 0, 1/3, 2/3, or 1 or a value of 1/2 of the width is used. As in the case, the standard main body data can be easily converted into data for drawing the contour line.

As described in claim 11, when both side portions of the basic element are configured to generate contour line shapes of both end portions based on detailed shape data described by an outline method, the detailed shape thereof Since a large amount of outline font data that has already been created can be used as it is as data, it is not necessary to create new font data for all character patterns.

According to the high quality character output device of the twelfth aspect, the control means draws the character pattern based on the font data read from the storage means. As described above, since the font data including the standard main body data and the character pattern data, which requires a small amount of data as described above, may be stored, the storage capacity required for the storage means is reduced, and as a result, The hardware cost can be suppressed.

According to the high quality character output device of the thirteenth aspect, the element data in the character pattern data includes the coordinate data indicating the shape of the core line, the width of the main body portion and the standard main body portion data. Since it is represented by the difference sample value indicating the difference from the standard width of the main body indicated by the sample value of, the character pattern data becomes relatively simple, and the dynamic range of the difference sample value is narrow. As a result, the data amount of the character pattern data is reduced, which has the advantage of further reducing the storage capacity required for the storage means.

According to the high quality character output device of the fourteenth aspect, when the control means restores the contour line shapes on both sides of the main body of the basic element, the control unit corresponds to the specified basic element. By transforming the standard core shape indicated by the reference data in the standard main body data described above to the position indicated by the coordinate data in the character pattern data and scaling, the core wire of the specified basic element The shape is restored, and the width of the main body of the specified basic element is restored by adding the differential sample value in the character pattern data to the sample value in the standard main body data corresponding to the specified basic element. Come to do. In this case, since the relatively complicated operation required when the target basic element is restored from the basic element indicated by the standard main body data is only the operation for coordinate conversion as described above, the control means This reduces the amount of calculation when restoring the basic element.

According to the high quality character output device of the fifteenth aspect, when the control means restores the contour line shapes on both sides of the main body portion of the basic element, it is restored by the above-described scaling operation. Since the core line shape is corrected based on the difference data in the character pattern data, the core line shape can be accurately restored.

As described in claim 16, as the sample value indicating the width of the main body portion corresponding to one contour line, the parameter t in the cubic Bezier curve expressing the contour line is described.
= 0, 1/3, 2/3, 1 or a value indicating the width of the main body portion at each point or a value of 1/2 of the width is used, the contours on both sides of the main body portion The data showing the control points of the cubic Bezier curve for approximating the line shape can be easily obtained, and the standard main body data can be easily converted into the data for drawing the contour line.

Also in the high quality character output device according to the seventeenth aspect, since the storage means may store the font data including the standard main body data and the character pattern data, which requires a small amount of data, The storage capacity required for the storage means is reduced, and the hardware cost can be suppressed.

Also in the high quality character output device according to the eighteenth aspect, the element data in the character pattern data includes the coordinate data indicating the shape of the core line, the width of the main body portion, and the standard main body portion data. Since it is expressed by the difference sample value indicating the difference from the standard width of the main body portion indicated by the sample value, the data amount of the character pattern data is reduced as described in claim 13. There is an advantage that the storage capacity required for the storage means is further reduced.

According to the high-quality character output device of the nineteenth aspect, when the control means restores the contour line shapes on both sides of the main body of the basic element, the control unit corresponds to the specified basic element. The contour of the standard element specified by converting the standard contour shape indicated by the reference data in the standard main body data to the position indicated by the coordinate data in the character pattern data and performing scaling. The width of the main body of the specified basic element is restored by restoring the shape of the line and adding the difference sample value in the character pattern data to the sample value in the standard main body data corresponding to the specified basic element. Will be restored. Therefore, also in this case, as in the case of the fourteenth aspect, the amount of calculation when the control means restores the basic element can be reduced.

According to the high quality character output device of the twentieth aspect, when the control means restores the contour line shapes on both sides of the main body portion of the basic element, it is restored by the above-described scaling operation. Since the contour line shape will be corrected based on the difference data in the character pattern data,
The contour line shape can be restored accurately.

In the case of the structure as claimed in claim 21,
The data indicating the control points of the cubic Bezier curve for approximating the contour line shapes on both sides of the main body portion can be easily obtained, and the contour line is drawn from the standard main body portion data as in the case of claim 13. You can easily convert it into data to do.

In the case of the structure as claimed in claim 22,
Since a large amount of outline font data that has already been created can be used as the detailed shape data stored in the storage means, it is not necessary to create new font data for all character patterns.

It is expressed as the specific element data Dc described by the outline method using the following Bezier curve, and the standard size (stroke length) is set for the other basic elements, and for each of the basic elements of the standard size, It is described in the following form.

That is, for example, the Chinese character "sa" shown in FIG. 5 is based on the Mincho typeface, and among the basic elements constituting the character pattern, the uneven portion is the "left side" basic element 11 consisting of curved strokes. And a "vertical" basic element 12 consisting of a linear stroke, and each basic element 11 and 12 is
Decorative parts 11a, 11b and 12a, 12b at both ends
(Indicated by a solid line in the figure) and the decorative portions 11a and 11b
Main part 11 which constitutes each part between the space and 12a, 12b
c and 12c (shown by broken lines in the figure) are combined.

In describing such a character pattern as font data, the main body portions 11c and 12c in the basic elements 11 and 12 forming the uneven portion,
The decorative portions 11a, 11b and 12a, 12b are expressed in different formats, and the part of the character pattern created is also expressed in the same format.

Specifically, for example, with respect to the main body portion 11c of the basic element 11, the shapes of the contour lines 11d and 11e on both sides of the main body portion 11c are defined by a core line 11f (shown by a one-dot chain line) passing between the contour lines 11d and 11e. It is described as standard main body part data Da which is a combination of reference data showing the shape and a sample value showing the width of the main body part 11c corresponding to the core wire 11f. In this case, as the reference data, a control point p0 for expressing the core wire 11f as a cubic Bezier curve (0≤t≤1) as shown in FIG. 6,
The coordinate information indicating p1, p2 and p3 is used. Further, as the sample value, each control of the parameter t = 0, 1/3, 2/3, 1 in the core c shown by a cubic Bezier curve as shown in FIG. 7 (corresponding to the core 11f shown in FIG. 5) The sample values w0, w1, w2, w3 corresponding to the width of the main body portion 11c at the points p0, p1, p2, p3 are used. In FIG. 7, the upper and lower contour lines 11c of the main body portion 11c are
The curves corresponding to d and 11e are indicated by c'and c ", respectively.

On the other hand, regarding the main body portion 12c of the linear basic element 12 shown in FIG.
The shapes of 2d and 12e are defined by their contour lines 12d and 12
It is described as standard main body data Da which is a combination of reference data indicating the shape of a core wire (not shown) passing through the middle of e and a sample value indicating the width of the main body 12c corresponding to the core wire.

On the other hand, the contours of the decorative portions 11a, 11b and 12a, 12b are expressed as the detailed shape data Db described by the outline method using a cubic Bezier curve having a plurality of coordinate point information. Has been done. Then, a combination of the standard main body data Da and the detailed shape data Db for one basic element as described above,
In addition, the specific element data Dc is prepared for all basic elements (of standard size) necessary for expressing a group of character patterns, and the font data is divided for each basic element. Is stored in the first storage area 21 of the font ROM 2.

Of the basic elements shown in FIG. 4, two types of main parts are included for the "magenta", "mages", "tatesen + horizontal", and "key". Since it is composed of the decorative portions connecting the portions and the decorative portions at both end portions, the standard main body portion data and the detailed shape data corresponding to the numbers thereof are prepared.

By the way, the standard main body data Da that describes the main body of the basic element as described above expresses a basic element having a standard size. Therefore, for example, the Chinese character "sa" shown in FIG. In the case of generating the "left-sided" basic element 13 having a large stroke length existing in the part where the stroke is formed, it is necessary to correct the standard main body portion data Da, and the correction method will be described below.

That is, FIG. 8 (a) shows the main body of the standard basic element for "left side", that is, the main body described as the standard main body data Da, and the contour lines L1 and As described above, the shape of L2 includes control points p0, p1, p2, p3 for expressing the core line L3 by a cubic Bezier curve, and sample values w0, w1, w2 indicating the width of the main body, It is expressed in combination with w3. The contour line L of such a standard basic element
The shapes of 1 and L2 are the basic elements as shown in FIG.
3 '), the standard end element L3 has a core L3 having a starting point A and an ending point B (control points p respectively).
(Corresponding to 0 and p3), the starting ends A'and B'of the core wire L3 '.
(Map to control points p0 'and p3' of core L3 ')
Sample values w0, w1, w2 indicating the width of the standard main body
, W3 need to be converted into sample values w0 ′, w1 ′, w2 ′, w3 ′ indicating the width of the main body portion of the basic element shown in FIG. 8B, and in order to perform the correction more accurately, Must move the control points p1 and p2 to the control points p1 'and p2' according to the actual shape of the core L3 '.

In the present embodiment, in order to map the starting end A and the ending end B of the core wire L3 to the starting ends A'and B'of the core wire L3 'while scaling, for example, affine transformation (parallel movement, x-axis) without rotation. And y-axis separate enlargement / reduction combination) are used.
Coordinate data ZA indicating the positions of the starting points A'and B'of 3 '
, And ZB are determined for each basic element forming each character pattern. In addition, control points p1 and p2 are set to control point p
Control points p1 * and p2 * (see FIG. 8 (b)) obtained when the affine transformation as described above is applied to coordinate points p1 and p2 to move to 1'and p2 ' Point p1 ',
Difference data ΔP1 and ΔP2 showing the difference between p2 ′ and p2 ′
(The vector values as shown in FIG. 8C) are used, and the difference data ΔP1 and ΔP2 thereof are determined for each basic element forming each character pattern.

Further, in order to convert the sample values w0 to w3 indicating the standard width of the main body into w0 'to w3', it is usual to perform the affine transformation as described above. In this embodiment, both sample values w0 to w3 and w
Difference sample values Δw0 to Δw3 indicating differences between 0 ′ to w3 ′ are used, and these difference sample values Δw0 to Δw3 are used.
Is determined for each basic element forming each character pattern.

Incidentally, the reason why the affine transformation is not used for the transformation of the sample values w0 to w3 in this way is that the line width of the basic element is generally constant rather than proportional to the size of the element. This is because we focused on the characteristic peculiar to character patterns, which often have values.

As described above, the standard main body data Da, the detailed shape data Db and the specific element data Dc are stored in the first storage area 21 (see FIG. 2) of the font ROM 2 as described above. In the second storage area 22, character pattern data K as described below is stored.

That is, the character pattern data K is obtained by decomposing each character pattern into basic elements for a predetermined character pattern (for example, Kanji) in a group of character patterns, and combining each of these character patterns with the basic elements. It is composed by combining the following data necessary for expressing by.

... control data necessary for describing each character pattern, such as which basic element is required to express the character pattern, ... representing the shape of each basic element constituting the character pattern Multiple element data. However, this element data includes the type data for expressing the type of the corresponding basic element, and each core line data indicating the shape of the core line passing through the center of the main body of the basic element (the difference from the coordinate data ZA and ZB described above). Data ΔP1 and ΔP2
Combination) and a sample value indicating the width of the main portion of the basic element (the difference sample values Δw0 to Δw described above).
(Corresponding to 3) and
The description format is as shown in (c).

Here, the contents stored in the ROM 2 shown in FIG. 2 will be described with reference to a concrete example. That is, in the first storage area 21 of the ROM 2, standard main body data Da of standard sizes of all basic elements required for a group of character patterns, detailed shape data Db and specific element data Dc are stored in each basic It is stored in a state of being divided for each element. For example, address 2
2a stores standard main body data Da and detailed shape data Db corresponding to the basic element of "left side".

Further, the character pattern data K is stored in the second storage area 22 of the ROM 2 in a state in which the character pattern data K is divided for each character pattern. Corresponding character pattern data K is stored. In this case, the character pattern data K stored in each address of the second storage area 22 is as shown in FIG.
As shown in (b), a plurality of element data (see above) in a state of being associated with control data (see above)
Is in the state of remembering.

Now, FIG. 3 shows only the main part of the processing routine for developing the contour line patterns on both sides of the main body in the basic elements forming the character pattern, out of the control contents by the CPU 1. This will be described below. However, in the following, FIG.
An example will be described in which the standard basic element shown in (a) is corrected to the basic element shown in FIG.

That is, when newly developing a character pattern, the CPU 1 reads the character pattern data K corresponding to the character pattern from the font ROM 2 and, based on the control data in the pattern data K,
The standard main body data Da required for expressing the character pattern is read from the font ROM 2 (step S
1). The character pattern data K read as described above includes element data (coordinate data ZA and Z).
B, difference data ΔP1 and ΔP2, difference sample value Δw
(Including 0 to Δw3) is also included.

Next, in step S2, the core line L3 (FIG. 8) indicated by the read standard main body part data Da is displayed.
A starting point A and an ending point B (corresponding to the control points p0 and p3) of (a) are core lines L3 '(FIG. 8B) indicated by the coordinate data ZA and ZB in the read pattern data K.
Starting points A'and B '(corresponding to control points p0' and p3 ')
The affine transformation T described above for mapping to is obtained. Furthermore, in step S3, the affine transformation T is converted to the core line L.
The coordinate information indicating the control points p1 * and p2 * of the Bezier curve having a shape close to the target core line L3 ′ is obtained by applying the coordinate information indicating the control points p1 and p2 of 3 to the coordinate information.

In step S4, the control points p1 * and p2 * are set.
The coordinate data of the control points p1 'and p2' corresponding to the core line L3 'is obtained by adding the difference data .DELTA.P1 and .DELTA.P2 in the read pattern data K to the coordinate information of. Further, in step S5, the difference sample value Δ in the read pattern data K with respect to the sample values w0 to w3 (indicating the width of the main body of the core L3) included in the standard main body data Da.
By adding w0 to Δw3, sample values w0 'to w3' indicating the width of the main body portion of the core wire L3 'are obtained.

Then, in step S6, based on the coordinate information of the control points p0'-p3 'relating to the core L3' obtained as described above and the sample values w0'-w3 'indicating the width of the main body, the core is obtained. The contour lines L1 'and L2' on both sides of L3 'are developed (drawn) in the character pattern development memory 3 as a bit image. The expansion of the decorative portions at both ends of the basic element is performed based on the detailed shape data Db before or after the expansion of the contour lines L1 'and L2' as described above, for example. Further, in actuality, in step S6, scaling is performed so that the output character pattern has a desired size (point number).

Here, when the control of FIG. 3 is performed, step S5 may be executed before step S2, and the order relation between step S5 and steps S2-4 is fixed. There is no need. Also,
A configuration in which the control in steps S3 and S4 is performed in the opposite direction, for example, affine transformation is performed so that the start and end coordinates of the target core line shape L3 'are aligned with the start and end coordinates of the standard core line shape L3, thereby obtaining The difference may be obtained based on coordinate point information indicating the control point of the Bezier curve that is set, that is, the difference data ΔP1 and ΔP2.
Should be treated as relative data.

When the character pattern is generated, the connection between the main body portion and the decorative portion in the basic element may be performed as follows, for example. That is,
FIG. 9 shows a main connection 1 shown in FIG. 5 as a basic connection example.
The case where the connection between 1c and the decorative portion 11b is performed is shown. In FIG. 9, the decorative portion 11b is made of PE0, P
It is expressed as a Bezier curve with E1, PE2, and PE3 as control points. In this case, the control points PE0 and PE3 are
Since it is the same as each one of the control points of the cubic Bezier curve representing the contour lines 11d and 11e on both sides of the main body portion 11c, these can be used as they are, and the remaining control points PE1 and PE2 are
The contour lines 11d and 11e are present on the tangents of the control points PE0 and PE3, and can be represented by two types of scalar amounts LE1 and LE2 indicating the distances from the control points PE0 and PE3. Therefore, in this case, the detailed shape data Db for expressing the decorative portion 11b by the outline method using the cubic Bezier curve is, for example, as shown in FIG. 10, a type for specifying the type NX of the decorative portion 11b. The data can be described only by a combination of the data and the distance data indicating the two types of scalar amounts LE1 and LE2, and as a result, the data amount can be suppressed.

In summary, in the present embodiment described above, standard sizes are set for a plurality of basic elements that form a group of character patterns including Chinese characters, and
For each of these basic elements, the outline shape on both sides of the main body excluding both end portions is stored in the font ROM 2 as standard main body data Da expressing Bezier curves, and the group of character patterns is stored in the basic element. The character pattern data K for reconstructing the character pattern based on the main body data Da is stored in the font ROM 2 and the CPU 1 actually generates the character pattern. By correcting the shapes of the contour lines on both sides of the main body of the standard basic element indicated by the standard main body data Da read from the same, based on the character pattern data also read from the font ROM 2, the basic of the target character pattern is obtained. Restores the contour line shapes on both sides of the main body of the element Unishi to have.

In this case, the standard main body data Da is
For each of the basic elements of standard size, the contour line shapes on both sides of the main body, excluding both ends, are used as reference data indicating the shape of the core line passing through the middle of the contour lines and the main body part corresponding to the core line. Since it is described by combining it with the sample value indicating the width, the amount of data can be relatively reduced, and moreover, only a relatively small number of basic elements need to be described, and an enormous amount of one typeface is required. It is not necessary to describe a special character pattern, and the amount of data will be greatly reduced. Further, the character pattern data K is described by a combination of control data for specifying a basic element necessary for restoring each character pattern and element data expressing a difference between these basic element standard systems. Therefore, the character pattern data K itself is much simpler than the normal outline font data, and the amount of the data is greatly reduced.

As described above, the main body of each basic element forming the character pattern can be generated based on the standard main body data Da and the character pattern data K in which the data amount is greatly reduced. Therefore, as a result, the total font data amount is significantly reduced as compared with the conventional configuration. Therefore, the storage capacity required for the font ROM 2 for storing font data can be reduced, and the hardware cost can be suppressed.

The element data in the character pattern data K has a relatively simple description format as shown in FIG. 2C, and the information indicating the width of the main body of the basic element is the difference sample value Δw0. Since it is expressed as ~ Δw3, the dynamic range can be narrowed, and as a result, the data amount of the character pattern data can be reduced.
The storage capacity required for can be reduced.

The relatively complicated calculation required when the core line of the target basic element is restored from the standard core line of the basic element indicated by the standard main body data Da is the standard operation based on the standard main body data Da. Only the calculation for independently scaling the start and end positions of the core wire to the start and end positions indicated by the coordinate data ZA and ZB in the character pattern data K in the x-axis and y-axis directions is performed. Since the above-described scaling is not performed for the restoration of the width of the main body of the above, the amount of calculation at the time of restoring the basic element is reduced, and as a result, the load on the CPU 1 is reduced.

When the contour line shapes on both sides of the main body of the basic element are restored, the shape of the core line restored by the scaling operation as described above is corrected based on the difference data ΔP1 and ΔP2 in the character pattern data K. Therefore, the core line shape, and thus the contour line shape, can be accurately restored based on the difference data having a small dynamic range.

Since the outline shapes of both end portions of the basic element are expressed in another format (outline method in this embodiment), there is no restriction on the expression of the character pattern as in the prior art, and the expression of the expression is not restricted. You will be able to increase the degree of freedom. In this connection, since the contour line shapes of the both end portions of the basic element are expressed as the detailed shape data Db described by the outline method using the cubic Bezier curve, as the detailed shape data Db of them,
A large amount of outline font data already created can be used. As a result, it is not necessary to create new font data for all the character patterns, and it is possible to reduce the labor required to create each character pattern.

Furthermore, the standard main body data Da is a parameter t = 0, 1/3, 2 in the cubic Bezier curve as a sample value indicating the width of the main body corresponding to the core represented by the cubic Bezier curve. Since it is configured to use the width value of the main body portion at each point of / 3 and 1, it is possible to perform a simple calculation of data indicating the control points of the cubic Bezier curve for approximating the shape of the contour line. You will be able to ask.
Therefore, the standard main body data Da can be easily converted into the data for drawing the contour line, and the detailed shape data D described by using the cubic Bezier curve is obtained.
The conformity with b is improved. However, in this case,
As the sample value, a value of 1/2 of the width of the main body portion at each point of the parameter t = 0, 1/3, 2/3, and 1 in the cubic Bezier curve may be used.

In the above embodiment, in order to affine-convert the starting end A and the ending end B of the core wire L3 into the starting ends A'and B'of the core wire L3 ', the starting end A'on the character pattern data K side.
Although the coordinate data ZA and ZB indicating the positions of B and B'are used, it is also possible to use the coordinate data affine in advance on the character pattern data K side.

Further, in the above-mentioned embodiment, the shape of the contour lines on both sides of the main body of the basic element is made up of a combination of reference data showing the shape of a core line passing through the middle and a sample value showing the width of the main body. Although the configuration is described as the standard main body portion data Da, the shape of the contour line is defined by reference data in which one contour line is represented by, for example, a cubic Bezier curve, and the width of the main body portion corresponding to the one contour line. The configuration may be described as standard main body data that is a combination with the sample values shown. Furthermore, in the above embodiment, the cubic Bezier curve is used to represent the standard main body data Da and the detailed shape data Db. However, instead of this, another function curve such as a spline curve may be used. Is also good.

In the above embodiment, the coordinate data ZA and ZB indicating the start and end of the target basic element are prepared in the element data of the character pattern data K, and the core line L3 indicated by the standard main body data Da is prepared. The starting point A and the ending point B in FIG. 8A are referred to as the coordinate data Z.
The affine transformation for mapping to the starting ends A'and B '(corresponding to the control points p0' and p3 ') of the core line L3' (see FIG. 8B) indicated by A and ZB is made. The structure of the part can be modified as described below.

That is, by giving the actual position coordinates (this is called the starting end coordinate ZC) only to one end of the core wire of the target basic element, for example, the starting end, the standard indicated by the standard main body data Da. A parallel movement destination of the starting end A of the core line L3 is defined, and the scaling factor ax in the x-axis direction and the y-axis direction of the core line L3 having the starting end coordinate ZC as the origin.
And ay are described as coordinate data in the element data. In this case, the description format of the element data may be set as shown in FIG.

Also in this case, instead of the above-mentioned data regarding the core line, the starting end coordinates and the scaling factor regarding one contour line may be described. Further, in this example, the starting end coordinates ZC are given to define the parallel movement destination of the starting end A of the standard core line L3 indicated by the standard main body data Da, but the starting end A (end B) on the target basic element is defined. However, it may be configured so as to specify the corresponding position.
