Description

  The present invention relates to a character display device, a character display method, and a computer program for character display, and more particularly, to a character display for displaying a continuous character such as a cursive script.

  Conventionally, as a device that performs various processing on display characters, each element that constitutes a character is stored in a stroke order, and when there is a predetermined instruction, each element that constitutes the character is displayed in a stroke order. there were.

  In addition, for each of the above elements, the start point, the midpoint, and the end point are stored, and when there is a predetermined instruction, the elements constituting the character are displayed in the order of stroke.

Japanese Patent Laid-Open No. 9-6769 Japanese Patent Laid-Open No. 10-39736 Japanese Patent No. 2569489 Japanese Patent Publication No. 7-89274

  However, in such a conventional character display device, each displayed character is displayed independently. This made it impossible to grasp the connection between each character, and did not understand the “flow” from one character to the next, which is an important element of ancient calligraphy. An object of the present invention is to connect displayed characters to create an atmosphere like a brush calligraphy penmanship character connected in series.

  In order to achieve the above object, the present invention draws a means for storing character information for drawing a plurality of characters in association with each character, and a connecting line connecting one of the plurality of characters and the other. The character information and the connecting line information include the end point information at the point where each character or two of the connecting lines are connected, and the character or connecting line 2 at the end point. It is located on the extension of one tangent line that touches one, and consists of direction point information that determines the magnitude of curvature of the same character or connecting line. At this end point, both of the character or connecting line are both of the one tangent line The curve extends in the opposite direction along the direction, and the curvature increases as the direction point moves away from the end point. The character information is read according to a predetermined instruction and a plurality of characters are displayed. So, by another predetermined instruction, it reads the connection line information, and so as to display the connection line connecting the displayed plurality of characters.

  Thereby, the character displayed can be connected and the atmosphere like the character of the brush calligraphy penmanship connected in series can be taken out. The connection between each character can be shown, and the “flow of writing” from one character to the next can be grasped. The character is composed of an element 21 and an element connecting line 22, and the connecting line includes a character connecting line 23 and an element connecting line 22.

  In addition, the characters (element 21, element connecting line 22) and the connecting line (character connecting line 23) are smoothly connected because they extend in the opposite direction along one tangent at each end point. And while each end point is connected smoothly, the direction point can be changed and the magnitude | size of a curve can be changed. Moreover, even if the direction point is changed to change the curvature, the smoothness of the connection between the end points is maintained.

  Furthermore, no matter how the connecting line (character connecting line 23, element connecting line 22) or the bending state of the element 21 changes, the direction point information only needs to be changed R, and the connecting line (character connecting line 23 , It is not necessary to change the allocation of the end point information to the element connecting line 22) and the element 21, and it is possible to easily cope with the change of the bending state.

These communication means are Internet communication systems.

(2) Character information (element information and element connection line information)
FIG. 2 shows character information and element connection line information stored in the program / data storage unit 16 or the information storage unit 17. The example of FIG. 2 shows a hiragana character of “fu”. The character information is composed of one or more element information and element connection line information constituting each character.

  The element 21 indicates a line (curve) of one side and one side (one stroke / one stroke / one stroke) constituting each character, the element connecting line 22 indicates a line (curve) connecting these elements, and the connecting line is A line (curve) connecting each character, connecting the end / end / end / end / connection point / contact of the previous character to the start / start / start / connection / contact of the next character.

  Each element information and each element connection line information includes two anchor points (end points, connection points, contact points) 31 and two control points (direction points) 32 of a Bezier curve described later. The anchor point (end point / connection point / contact point) 31 is coordinate data of the start point / start point of each element and each element connection line, and the control point (direction point) 32 is the anchor point of each element and each element connection line. The direction of the end at (end point / connection point / contact point) 31 and the magnitude of the curve of the line are shown.

  The line connecting the anchor point (end point / connection point / contact point) 31 and the control point (direction point) 32 becomes a control handle (tangent line), and each element and the end of each element connection line / connection point / inclination of the contact / Represents the slope. This inclination is indicated by a straight line connecting two coordinate points.

  Each element 21 and each element connection line 22 are drawn from two anchor points (end points / connection points / contact points) 31 and two control points (direction points) 32, but each element and each element connection line are mutually connected. Since they are connected, the last end anchor point (end point / connection point / contact) 31 and the next start anchor point (end point / connection point / contact) 32 are overlapped and shared.

  In addition, the end control point (direction point) 32 connected to the end and the control point (direction point) 32 of the next start point are in opposite directions across the anchor point (end point / connection point / contact point). In addition, a straight line connecting the last control point (direction point) 32 of the end point and the next control point (direction point) 32 of the start point passes through the anchor point (end point / connection point / contact point) 31.

  Accordingly, the direction of the end point at the end of each element 21 and each element connection line 22 and the direction of the next start point connected to the element 21 and each element connection line 22 coincide with each other, and the smooth connection between each element 21 and each element connection line 22 is achieved. realizable. This also applies to the connection points / connection points between the elements 21 and the element connection lines 22 and the character connection lines.

  Note that there is no coincidence of the directions as described above at the connection point / connection point of the element connection line 22 from the element 21 on the left side of “F” to the point on the right side. This is possible in some cases.

  An element connection line 22 exists between the four elements 21 of “F”. This element connection line information is also composed of the anchor point 31 and the control point 32 (control handle (tangent)).

  Character linking line information is created between two characters, such as “fu” and another character. This character connecting line information also includes the anchor point 31 and the control point 32 (control handle (tangent)). The character connection line information and the element connection line information constitute the connection line information.

  Each element 21, each element connection line 22, and each character connection line 23 of each character are connected to one line so that each anchor point 31 is connected with a degree of curvature corresponding to each control point. Accordingly, it is possible to draw a character such as a living one-stroke writing in which “connection” occurs in each character such as a brush calligraphy penmanship.

  Since the control handles (tangent lines) of the two lines to be connected are the same at the connecting points of the elements 21, the element connecting lines 22, and the character connecting lines 23, there is no bending at each connecting point. , Smoothly curved and connected. Therefore, each character, such as a brush calligraphy penmanship, is “connected” and a live character can be drawn.

  Each element information and element connection line information as described above is stored separately for each character written in the program / data storage unit 16 in the stroke order. The character / information storage unit 16 stores all the character information for each of hiragana, katakana, kanji, alphabet, and symbols. Symbols include those that are close to figures. Element connection line information connecting each element 21 of each character is also stored together with each element information of each character.

  The coordinate values of the anchor point 31 and the control point 32 of the character information stored in this way are determined with respect to the standard character size (predetermined point), and when the character size (number of points) is changed. Accordingly, each coordinate value can be changed in proportion.

  Each element 21, each element connection line 22, and each character connection line 23 may be determined and formed by a spline curve or other calculation curve in addition to a Bezier curve to be operated next. The Bezier curve is a curve connecting two points, which is determined by the inclination angle at the two points and the magnitude of the curve.

(3) Character connecting line information FIG. 3 shows character connecting line information. When the display position of each character is individually changed and the spacing, separation direction, and separation direction of each character change, the length, thickness, inclination, curvature, and curvature of this character connection line information are changed accordingly. The direction is changed.

  On the other hand, the element information of each character and each element connection line information only change in a similar shape according to the change in the size of the character. Of course, the thickness, inclination, curvature, and bending direction of the element information and each element connection line information may be changed according to the change in the size of the character.

In addition to the character connecting line 23, each element 21 and each element connecting line 22 of each character is determined and drawn as follows. Two anchor points (end points, connection points, _{contacts) P1 (x 1, y 1} ), P4 (x 4, y 4) and two control points (direction _{points) P2 (x 2, y 2} ), P3 (x ₃ , y ₃ ), a connecting line is drawn that falls within these four points.

  In this case, the anchor point P1 coincides with the end point of the previous character, the anchor point P4 coincides with the start point of the subsequent character, the direction line P1-P2 coincides with the direction of the end of the previous character, and the direction line P4- P3 coincides with the direction of the beginning of the subsequent character.

  The anchor point P1 of the character connecting line 23 uses the anchor point 31 that is the end point of the previous character as it is, and the anchor point P4 uses the anchor point 31 that is the start point of the subsequent character as it is.

  Further, the control point P2 (coordinates) of the character connecting line 23 is a point (coordinates) in which the control point (direction point) at the end point of the previous character is point-symmetric with the anchor point (end point / connecting point / contact point) 31 at the end point. The control point P3 (coordinates) of the character connecting line is a point (coordinates) in which the control point 32 at the starting point of the subsequent character is point-symmetric with respect to the anchor point 31 at the starting point. In this case, the control point (direction point / connection point / contact point) 32 obtained for each point object is moved or corrected to a point further extended from or closer to the anchor point (end point / connection point / contact point) 31. Also good.

  Both ends of the connecting line are in contact with the direction line P1-P2 and the direction line P4-P3. Then, each of the three straight lines P1-P2, P2-P3, P3-P4 is divided into two to connect the dividing points, and the connected line and the remaining dividing lines of P1-P2, P2-P3 are further divided into two. And connect the dividing points. If the connection with such two divisions is repeated, a connecting line as shown in FIG. 3 can be drawn.

  Such a connecting line is drawn by the following arithmetic expression using the coordinate values, and is output to the output unit 13 such as the display or the printer. Similarly, each element 21, element connecting line 22, and character connecting line 23 of each character is drawn by the following arithmetic expression using the coordinate values and output to the output unit 13 such as the display or printer.

X = (1-t) ³ x ₁ +3 (1-t) ² x ₂ +3 (1-t) ² x ₃ + t ³ x ₄
Y = (1-t) ³ y ₁ +3 (1-t) ² ty ₂ +3 (1-t) t ² y ₃ + t ³ y ₄
0 ≦ t ≦ 1
Here, when t = 0, X = x ₁ and Y = y ₁ , and when t = 1, X = x ₄ and Y = y ₄ .

  The above arithmetic expression is basic, and if the characters (element 21, element connection line 22) and the connection line (character connection line 23) can be drawn, some changes are possible. For example, various constants and numerical values are added to the whole arithmetic expression or each term, such as multiplication / division / addition, or exponents “3”, “2”, “ The value of “1” can also be changed to “6” “4” “2”, “9” “6” “3”, “4.5” “3” “1.5”. However, the order of the magnitudes of these index values “3”, “2”, and “1” is not changed. However, it may be changed.

  FIG. 4 shows an example in which the length, direction (inclination), curvature, and bending direction of the character connecting line 23 are changed. In order to change the length of the character connecting line 23, the interval / length of the anchor points (end points / connecting points / contact points) P1, P4 is changed. Accordingly, the degree of curvature of the character connecting line 23 is reduced and the character connecting line 23 becomes flat. This change process is executed when the interval between two characters connected by the character connecting line 23 is increased.

  In this case, the control point (direction point / connection point / contact point) P2 (or P3) may be moved in parallel with or without the movement of the anchor point (end point / connection point / contact point) P1 (or P4). Alternatively, the movement may be different from the anchor point (end point / connection point / contact point) P1 (or P4).

  If translated, the tangent direction to the direction line P1-P2 and the direction line P4-P3 of the connection line at the anchor point (end point / connection point / contact point) P1 (or P4) is not changed. Therefore, the state where the connection point between the end of the character and the connection line is smooth is maintained.

  If the translation is not performed, the connection point between the end of the character and the connection line becomes a bending point, but if it is not moved, processing such as computation for drawing the connection line becomes easy. When the movement is different, the inclination / inclination of the connecting point between the end of the character and the character connecting line 23 is changed according to the change in the character interval, and the end or the end of the preceding character is changed according to the character interval. The direction / direction of the element at the beginning of the character can be changed.

  Even if the translation is not performed, the control point (direction point / connection point / contact point) 32 of the end element of the preceding character or the control point (direction point) 32 of the element at the beginning of the subsequent character can be changed in conjunction. For example, the connection point between the end of the character and the connection line becomes smooth.

  In the case of the above movement, for example, the movement amount of the control point (direction point) P2 (or P3) is 1/2, 2/3 of the movement amount of the anchor point (end point / connection point / contact point) P1 (or P4), 1/3, 3/4, 2/4, 1/4,..., And so on, are made smaller than the movement amount of the anchor point (end point / connection point / contact point) P1 (or P4).

  The movement direction of the control point (direction point) P2 (or P3) is the same as the movement direction of the anchor point (end point / connection point / contact point) P1 (or P4). The movement direction of the control point (direction point) P2 (or P3) may be different from the movement direction of the anchor point (end point / connection point / contact point) P1 (or P4).

  In order to change the direction (inclination) of the connecting line, the control point (direction point) P2 or P3 is moved to change the direction of either the direction line P1-P2 or the direction line P4-P3. In this case, the control point (direction point) P2 (or P3) is not translated with respect to the anchor point (end point / connection point / contact point) P1 (or P4).

  In order to change the curvature of the connecting line, the control points (direction points) P2 and P3 are moved along the direction line P1-P2 and the direction line P4-P3. When the control points (direction points) P2 and P3 are moved along the extending direction of the direction line P1-P2 and the direction line P4-P3, the curvature of the connecting line increases. When the control points (direction points) P2 and P3 are moved along the direction line P1-P2 and the direction line P4-P3, the degree of curvature of the connecting line decreases.

  In order to change the bending direction of the connecting line, the amount of movement of the control points (direction points) P2 and P3 is changed to be nonuniform when changing the bending degree of the connecting line. If the amount of movement of the control point (direction point) P2 is large and the direction line P1-P2 is longer, the bending direction of the connecting line is inclined toward the direction line P1-P2.

  If the amount of movement of the control point (direction point) P3 is large and the direction line P3-P4 is longer, the bending direction of the connecting line is inclined toward the direction line P3-P4. The same applies even if the direction line P1-P2 or P3-P4 is shorter.

  Further, when the control point (direction point) P2 or P3 is moved so that the control points (direction points) P2 and P3 are located on the opposite sides of the connection line, the connection line is not “U” -shaped. Instead, it curves in an “S” shape as shown in FIG. In this case, the line connecting the control points (direction points) P2 and P3 passes through the inflection point of the "S" -shaped curve and coincides with the tangent line of this inflection point.

  The process of drawing the connecting line as described above and the change of the length, inclination / tilt, curvature, and bending direction are executed as it is for each element of each character and each element connecting line in addition to the character connecting line. it can.

  Such a character connecting line 23 is displayed simultaneously with the element 21 and the element connecting line 22, or is displayed with a timing shift / delay according to a predetermined instruction. The character connecting lines 23 are displayed simultaneously or sequentially / gradually one by one according to a predetermined instruction or for each predetermined instruction.

  The length, inclination / tilt, curvature, and bending direction of the element 21, the element connecting line 22, and the character connecting line 23 are the drawing speed S, drawing thickness W, color, thickness, density, and saturation described later. , Brightness, character factor, etc. In this case, the control points (direction points) P2 and / or P3 and / or anchor points (depending on the drawing speed S, drawing thickness W, color, thickness, density, saturation, lightness, and character factor) The position coordinates of the end points / connection points / contacts P1 and / or P4) are changed.

  The character connecting line, the element 21, and the element connecting line 22 are displayed in mutually different colors, different thicknesses, different densities, different brightnesses, different saturations, or the same color, same thickness, same density, same brightness, same It is displayed with saturation. In this case, the color, thickness, density, saturation, and brightness of each character may be the same or different, and the color, thickness, density, saturation, and brightness of each character linking line are It may be the same or different.

  In this case, for each of the read information of the character connection line 23, element 21, and element connection line 22, the color, thickness, density, saturation, brightness, drawing speed S, drawing thickness W, character The factor information is added and sent to the output unit 13.

  The change in the length, thickness, inclination, curvature, and bending direction of the character connecting line 23 described above is executed in response to the case where the display positions of the plurality of characters are individually changed. Thereby, according to the arrangement state of each character, the state of the connection line (character connection line) is changed, the character arrangement and the state of the character connection line 23 are matched, and the atmosphere of the writing / calligraphy / penmanship character arrangement Can be optimized.

  When the character (element 21, element connecting line 22) and the connecting line (character connecting line 23) are drawn / drawn / displayed in the above-described arithmetic expression, the opposite points are taken along one control handle (tangent) at each end point 31. Since it extends in the direction, the element 21, the element connecting line 22, and the character connecting line 23 are smoothly connected.

  And while each end point 31 is connected smoothly, the direction point 32 can be changed and the magnitude | size of the curve of the element 21, the element connection line 22, and the character connection line 23 can be changed. Moreover, even if the direction points 32 are changed to change the magnitude of the curvature, the smoothness of the connection between the end points 31 is maintained.

(4) Thickness of Character Connection Line 23, Element 21, and Element Connection Line 22 FIG. 5 shows a drawing process of the thickness of the character connection line 23, element 21, and element connection line 22. First, the thickness (amplitude) W of the line is obtained from the anchor point (end point / connecting point / contact) P1 to the next anchor point (end point / connecting point / contact) P4 based on the following arithmetic expression ( FIG. 5 (1)).

W = a / 10 · sin θ (a: arbitrary constant)
θ indicates the position / phase / angle from the anchor point (end point / connecting point / contact) P1 to the next anchor point (end point / connecting point / contact) P4. “0 degree” (W = 0) and “180 degrees” (W = 0) at the next anchor point (end point / connection point / contact point) P4.

  Then, a thickness (amplitude) W is obtained for each predetermined angle of θ, for example, 10 degrees, 15 degrees, and 20 degrees, and a circle having a radius of the thickness (amplitude) W is determined for each predetermined angle of θ. Drawing processing is performed (FIG. 5 (2)). Then, these circles are filled with a predetermined color, for example, black (FIG. 5 (3)).

  As a result, some irregularities are formed on the outer edges of the character element 21, the element connecting line 22, and the character connecting line 23, thereby creating an atmosphere like a brushstroke / calligraphy / calligraphy character. In addition, the transparency, brightness, density, color, and saturation of the fill can be changed (FIG. 5 (4)).

  In this case, the transparency, lightness, and density can be changed by changing the distribution ratio of each pixel of black and white in the painted area. Further, the color can be changed by changing the distribution ratio of each pixel of the plurality of colors in the portion to be filled. Further, when the distribution ratio of each pixel of the color of the filled area and each pixel of black or white is changed, the color saturation, the color transparency, the color brightness, and the color density can be changed.

  If the constant a is changed, the thicknesses of the element 21, the element connecting line 22, and the character connecting line 23 can be changed. If this a is a variable of the above θ, for example, the thickness does not change in a sine wave shape, but the anchor point (end point / connection point / contact point) P1 or anchor point (end point / connection point / Contact) The line can be thickened near P4.

a = b · θ, a = b / θ, (b: arbitrary constant)
a = b · θ ⁿ , a = b / θ ⁿ
Here, n is an arbitrary number such as 1/2, 1/3, 2/3, 1/4, 2/4, 3/4,..., 1, 2, 3,.

  The constant a is changed according to the drawing speed S. Accordingly, the thickness of the character or / and the character connecting line is changed according to the drawing speed S. Therefore, it is possible to create an atmosphere as if the characters were actually drawn with a brush, calligraphy, or calligraphy, and it is possible to realize the thickness of the characters and / or character connecting lines that change according to the drawing speed.

  The drawing speed S indicates a speed at which characters and character connecting lines are drawn, and is input by an operator or determined by various character factors. This character factor includes character size, character spacing, character hiragana, katakana, kanji, symbols, alphabetic character types, character strokes (including hiragana and katakana strokes), transparency, brightness, and density. , Color, saturation, etc. The constant a itself is also input by the operator or determined by these various character factors.

  Further, the constant a is changed according to the character spacing D. Thereby, the thickness of the character or / and the character connecting line is changed according to the character spacing D. Therefore, it is possible to create an atmosphere as if the characters were actually drawn with a brush, calligraphy, or calligraphy, and it is possible to realize the thickness of the characters and / or character connecting lines that change according to the drawing speed.

  This character interval D is input by the operator as a character pitch / line pitch, or the coordinate interval between the anchor points (end points / connecting points / contact points) P of each character, and each character whose size is determined. This is the interval between the end / end / end coordinates and the start / start / start coordinates.

(5) Drawing speed of character connecting line 23, element 21, and element connecting line 22 Drawing speed of character connecting line 23, element 21, and element connecting line 22 is as follows. The circle drawing and filling are sequentially / sequentially performed using θ of the arithmetic expression for obtaining the above-mentioned line thickness (amplitude) W as a variable of the drawing speed S. Thereby, the character connecting line 23, the element 21, and the element connecting line 22 are drawn sequentially / gradually step by step at a predetermined speed.

W = a / 10 · sin θ (a: arbitrary constant)
θ = c · S, θ = c / S, (c: arbitrary constant)
θ = c · S ⁿ , θ = c / S ⁿ
Here, n is an arbitrary number such as 1/2, 1/3, 2/3, 1/4, 2/4, 3/4,..., 1, 2, 3,.

  The drawing speed S is changed by the character factor, drawing thickness W, transparency, lightness, density, color, and saturation. In this case, information on these colors, thickness, density, saturation, lightness, drawing speed S, drawing thickness W, and character factor is calculated and combined with the drawing speed S. Such arithmetic synthesis is executed for each element information, element connection line information, and character connection line information.

(6) Examples of Characters and Character Connection Lines FIGS. 6 and 7 show display examples of hiragana characters and character connection lines 23, and FIG. 8 shows display examples of kanji characters and character connection lines 23. FIG. 6A shows an example in which the elements 21 and element connection lines 22 of “sa”, “yo”, and “te” are displayed, and the character connection line 23 is not displayed. FIG. 6B shows an example in which the character connecting line 23 is displayed in addition to the characters “sa”, “yo”, and “te”.

  Similarly, FIG. 7A shows an example in which the “21” and “mi” elements 21 and the element connecting lines 22 are displayed and the character connecting lines 23 are not displayed. FIG. 7B shows an example in which the character connecting line 23 is displayed in addition to the characters “O” and “M”.

  6 (2) and FIG. 7 (2), the character connecting line 23 indicates that the character previously input each time “sa”, “yo”, “te”, “to”, and “mi” are sequentially input. A curve connecting the end / end of the character and the start / start of the next character is calculated and sequentially displayed step by step, and can be deleted by a predetermined instruction operation. Or, after entering all “sa”, “yo”, “te”, “wa”, and “mi”, a curve connecting the end / end of each character and the start / start of the next character entered by a specified pointing operation Can be calculated and displayed collectively or sequentially, and further erased collectively or sequentially by a predetermined instruction operation.

  In this way, the character connecting line 23 connects the displayed characters to each other, and an atmosphere like a brush calligraphy penmanship character connected in series can be obtained. The connection between each character can be shown, and the “flow of writing” from one character to the next can be grasped.

  FIG. 8 (1) shows an example in which “Raku”, “T” and “Michi” with the character connecting line 23 are input. On the other hand, FIG. 8B shows an example in which “Raku”, “T” and “Michi” without the character connecting line 23 are input. Thus, in contrast to FIG. 8 (2), in the example shown in FIG. 8 (1), the displayed characters are connected to each other, and it is possible to grasp the “flow of writing” from one character to the next. it can.

  Although the actual character connecting line 23 is not shown in FIG. 8A, the character connecting line 23 is stored on the information. In this way, even if the character connecting line 23 is not displayed, the displayed characters can be connected to each other, and the “writing flow” from one character to the next can be grasped.

  These characters are input on the keyboard of the input unit 12 by normal hiragana input, katakana input or romaji input and / or kana-kanji conversion operation, and the element information and element connection line information of the input font typeface. Is read out and output to the output unit 13.

(7) Character / Character Link Display Processing FIGS. 9, 10, and 11 are flowcharts of character / character link display processing. First, initialization processing is executed (step 00), error checking of the information storage unit 17 and program / data storage unit 16 of the server computer 2 and other initialization are performed.

  Next, if the character size (number of points), the character spacing (number of pitches) D, the drawing thickness W, the drawing speed S, the color, density, brightness, saturation, and the character factor are input. This is stored in the program / data storage unit 16 (internal storage medium / means) (step 02). The drawing thickness W, the drawing speed S, the color, the density, the lightness, the saturation, and the character factor are individually input for each element 21, element connecting line 22, and character connecting line 23.

  When characters such as hiragana, katakana, kanji, symbols, and alphabets are sequentially input from the input unit 12 such as a keyboard, or the character code string / group stored in the program / data storage unit 16 in advance is read out. (Step 03), this character code is temporarily stored in the RAM in the controller 14, temporarily displayed small on the edge of the display screen of the output unit 13 (Step 04), and other processing is executed (Step 31).

  Next, when an instruction to display a writing brush (calligraphy / calligraphy) is made with a predetermined key of the keyboard of the input unit 12 (step 05), character information corresponding to the input character code, that is, element information and element connection line information, Is read from the program / data storage unit 16 (internal storage medium / means), element information and element connection line information are obtained (step 06), and the captured size, interval, speed S, and thickness W are acquired. The color, density, brightness, saturation, etc. are output to the output unit 13 (steps 07, 08, 09, 10).

  The process for obtaining the element 21 and the element connection line 22 is the process for obtaining the Bezier curve from the control point (direction point) 32, the anchor point (end point / connection point / contact point) 31, and the like, and is as described above.

  Thus, the character element 21 is drawn as described above based on the anchor points (end points / connection points / contact points) P1 and P4 and the control points (direction points) P2 and P3 in the element information and the element connection line information. The In this case, although the drawing process of the element connection line 22 is also executed, the image data of the drawn element connection line 22 is not sent to the output unit 13 and is not displayed.

  In this case, anchor points (end points / connection points / contact points) P1 and P4 and control points (direction points) P2 and P3 according to the input character size (number of points) and character interval (number of pitches) D. Each coordinate value of is proportionally converted.

  At this time, the character element 21 is sequentially drawn on the output unit 13 at a speed corresponding to the input drawing speed S (step 07), and the character element is based on the drawing speed S as described above. The thickness of 21 is determined (step 08), and characters are displayed in a state corresponding to the color, density, lightness, and saturation (step 09).

  When an instruction to display the element connection line 22 is given by a predetermined key on the keyboard of the input unit 12 (step 11), the element connection line information after the drawing process is stored in the program / data storage unit 16 (internal storage medium / means). ) To obtain element connection line information (step 12), and outputs the information to the output unit 13 at a predetermined speed, thickness, color, density, lightness, saturation, and the like (steps 13, 14, 15). 16).

  As a result, the masked element connection line 22 is drawn as described above. The process for obtaining the element connection line 22 is a process for obtaining the Bezier curve from the control point (direction point) 32, the anchor point (end point / connection point / contact point) 31, and the like, as described above.

  At this time, the element connection line 22 is sequentially drawn on the output unit 13 at a speed corresponding to the input drawing speed S (step 13), and the element connection line 22 is based on the drawing speed S as described above. Is determined (step 14), and the element connection line 22 is displayed in a state corresponding to the color, density, lightness, and saturation (step 15).

  When an instruction to delete the element connection line 22 is given by a predetermined key on the keyboard of the input unit 12 (step 18), all the output of the element connection line information that has been drawn and output to the output unit 13 is stopped. Or can be stopped / erased step by step (step 19). Thereby, the character element connection line 22 can be displayed or deleted, and whether or not to display can be selected.

  Next, when an instruction to display the character connection line is given by a predetermined key on the keyboard of the input unit 12 (step 21), the display is made on the assumption that the element connection line 22 is displayed (step 22). Character linking line information for linking the existing characters is obtained (step 23), and the character linking line 23 is output to the output unit 13 at a predetermined speed, thickness, color, density, lightness, saturation, and the like (step 23). 24, 25, 26, 27). The process for obtaining the connection line information is a process for obtaining a control point (direction point) 32, an anchor point (end point / connection point / contact point) 31, and the like, and obtaining a Bezier curve from these, and is as described above.

  Since the character connection line is displayed on the premise of the element connection line display in this manner, the character connection line 23 is not displayed even though the element connection line 22 is not displayed. In addition, the connecting line 22 between the characters is also displayed, so that the atmosphere of the brushstroke / calligraphy / letter call can be comprehensively displayed. Of course, only the character connection line 23 may be displayed without displaying the element connection line 22.

  In this case, the character connection line 23 is drawn as described above based on the anchor points (end points / connection points / contact points) P1 and P4 and the control points (direction points) P2 and P3 in the character connection line information. At this time, the character connecting line 23 is sequentially drawn on the output unit 13 at a speed corresponding to the input drawing speed S (step 24), and the character connecting line 23 is based on the drawing speed S as described above. The character connecting line 23 is displayed in a state corresponding to the color, density, lightness, and saturation (step 26).

  When an instruction to erase the character connection line 23 is given by a predetermined key on the keyboard of the input unit 12 (step 28), all the output of the character connection line information that has been drawn and output to the output unit 13 is stopped. Or can be stopped / erased step by step (step 29). Thereby, the character connection line 23 which connects each character can be displayed or deleted, and it can be selected whether to display.

  When the color, density, lightness, and saturation of the element 21, the element connection line 22, and the character connection line 23 captured in steps 01 and 02 are individually changed, the element 21, the element connection line 22, and the character connection line 23 Each color, density, brightness, and saturation is changed individually.

  As a result, the color, density, brightness, and saturation of the element 21, the element connecting line 22, and the character connecting line 23 can be made different or the same, and the character and the character connecting line 23 or the element connecting line 22 can be clearly distinguished. It is possible to clearly identify and grasp the atmosphere of the brush / calligraphy / calligraphy for each element, and it becomes a brush / calligraphy / calligraphy connected to a series, which is useful for the teaching of brush / calligraphy / calligraphy.

  Further, as described above, when the drawing speed S is changed, the drawing thickness W is changed, so that characters (elements and / or element connecting lines) are arranged in accordance with the momentum / speed of the actual brush stroke. ) And / or the character connecting line 23 can be drawn with a brush / calligraphy / calligraphy, which is connected to a series of brushes / calligraphy / calligraphy, and is useful for teaching brush / calligraphy / calligraphy.

  Further, when the drawing speed S is changed, the color, density, lightness, and saturation of the element 21, the element connecting line 22, and the character connecting line 23 are changed. In this way, characters (elements and / or element connecting lines) and / or character connecting lines 23 can be drawn with a brush / calligraphy / calligraphy, resulting in a series of brushes / calligraphy / calligraphy, and a brush / calligraphy / calligraphy lesson. To help.

  Furthermore, when the drawing speed S is increased to the maximum value, the character connecting line 23 and / or the element connecting line 22 is drawn instantaneously. Accordingly, the character connection line 23 and / or the element connection line 22 can be displayed instantaneously and collectively (steps 12 to 16 and 23 to 27), or the display can be instantaneously deleted all at once. Can also be erased automatically (steps 19 and 29).

  As a result, the character and the character connecting line 23 or / and the element connecting line 22 can be compared, or the character with the character connecting line 23 or / and the element connecting line 22 can be compared with the non-character. You can analyze brushstrokes / calligraphy / calligraphy and help with brushstroke / calligraphy / calligraphy.

  By the erasing, a part where the element 21, the element connecting line 22 and / or the character connecting line 23 overlap can be partially erased, and the character flow / handwriting can be clarified in detail and in detail.

  Furthermore, the length, direction (inclination), curvature, and bending direction of the connecting lines 22 and 23 are changed according to the drawing speed S, the character spacing, and the character size. Therefore, if the drawing speed S is increased, the curvature of the character connecting line 23 and / or the element connecting line 22 can be reduced and the direction (inclination) can be reduced, and the brush / calligraphy / It is close to calligraphy and is useful for writing brush / calligraphy / calligraphy.

  The character display processing in steps 06 to 10, the element connection line display processing in steps 12 to 16, and the character connection line processing in steps 23 to 27 are collectively performed for a plurality of characters input in steps 01 to 04. . In this case, the character connecting line 23 is sequentially drawn between the characters from the upper character toward the lower character.

  However, for each character, for each character connection line 22, for each character connection line 23, for each character connection line 23, for character display processing in steps 06 to 10, for element connection line display processing in steps 12 to 16, and for character connection in steps 23 to 27. Line processing may be performed. After the above process, various other processes are performed (step 31) and repeated until an end instruction is given (step 32). When the end instruction is given, the character / character connecting line display process is ended. .

  9 to 11, it is possible to display only the element connecting line 22 in steps 12 to 16 or only the character connecting line 23 in steps 23 to 27 without displaying the characters in steps 06 to 10. Thereby, only the element connection line 22 or only the character connection line 23 can be examined.

(8) Character / Character Link Display Processing FIG. 12 shows a flowchart of another embodiment of the character / character link display processing. In this embodiment, each time a character is input, the character connecting lines 23 are displayed step by step. After the process of steps 00, 01, 02, if a character is input (step 03) and one or more characters have already been input (step 41), the character concatenation of steps 22-27 or 23-27 is performed. Line display processing is performed (step 42). Thereby, the character connecting line 23 extending from the end / end of the already displayed character is displayed, and the character connecting line 23 extends at a predetermined speed.

  And the display process of the element 21 and the element connection line 22 of the character of the said step 06-10, step 06-16, or step 06-10 * 12-16 is performed (step 43). In this way, the character connecting line 23 and the characters 21 and 22 are sequentially displayed in the stroke order.

  The above processing is repeatedly executed every time a character is input (step 03). After other processing (step 31), if an end instruction is given (step 32), a character / character connecting line display processing is performed. Ends.

  Whether or not to display the character connecting line in the character connecting line display for each character input can be selected for each character. In this case, if there is a predetermined instruction such as simultaneous operation of the shift key when inputting characters by operating the kana key or the like in step 03, the character connecting line display process (steps 22 to 27, 23 to 27) of step 42 is performed. ) Is executed, the character display process (steps 06 to 10, 06 to 16, and 12 to 16) in step 43 is performed. If this predetermined operation is not performed, the process in step 42 is not performed. Character display processing (steps 06 to 10, 06 to 16, and 12 to 16) is executed.

  The other processes are the same as the processes shown in FIGS. For example, the display of the character connection line 23 and the element connection line 22 can be erased instantaneously and collectively, or can be erased step by step (steps 19 and 29).

  The element connection line information is read in the stroke order together with the element information, and the element connection line 22 and the element 21 are displayed in the stroke order (step 43). Further, the display of the element connection line 22 and the character connection line 23 can be erased instantaneously and collectively, or can be erased step by step (steps 18, 19, 28, 29).

(9) Other Embodiments The present invention is not limited to the above embodiment, and various modifications can be made. For example, in the character / character connecting line display processing of FIGS. 9 to 11, the character element 21, the element connecting line 22, and the character connecting line 23 are displayed separately. They may be displayed in order of stroke.

  In this display, one element 21, element connecting line 22, and character connecting line 23 may be displayed sequentially and stepwise along the drawing speed S, or the drawing speed S may be maximized as described above. May be displayed.

  In this case, after displaying one element 21, element connection line 22, and character connection line 23, the next element 21, element connection line 22, and character connection line 23 are displayed after a predetermined time elapses by a timer process. become. In the sequential stepwise display, such a timer process may or may not be performed.

  Before the processes of steps 01 to 29, all the character connection lines 23 between the characters are obtained in advance for the inputted characters (step 23), and the obtained character connection line information between the characters. Are inserted between the information of each character. The element information and element connection line information of each character are in the stroke order. Therefore, all the elements 21, the element connecting lines 22, and the character connecting lines 23 across a plurality of characters are sorted in the stroke order.

  Next, the processes in steps 01 to 29 are combined into one, and the output unit 13 is configured such that the element 21, the element connecting line 22, and the character connecting line 23 have a predetermined speed, thickness, color, density, lightness, saturation, and the like. (Steps 24-27, 13-16, 07-10).

  In this case, based on the anchor points (end points / connection points / contact points) P1 and P4 and the control points (direction points) P2 and P3 of the element 21, the element connection line 22, and the character connection line 23, the element 21 and the element connection line 22 are provided. The character connecting line 23 is drawn as described above.

  At this time, the element 21, the element connection line 22, and the character connection line 23 are sequentially drawn on the output unit 13 at a speed corresponding to the input drawing speed S (steps 24, 13, and 07), and the above-described description. Thus, the thickness of the element 21, the element connecting line 22, and the character connecting line 23 is determined based on the drawing speed S (steps 25, 14, and 08), and the element is in a state corresponding to the color, density, lightness, and saturation. 21, element connection line 22 and character connection line 23 are displayed (steps 26, 15, 09).

  Thereafter, any one of the element 21, the element connecting line 22, and the character connecting line 23 can be selected and erased individually, or can be erased step by step (steps 18, 19, and 28). 29). In this case, the same erasure process as in steps 18, 19, 28, and 29 is also executed for element 21 between step 05 (NO) and step 11.

  In FIG. 9, as in FIG. 12, each time a character is input (step 03), the element 21 display and / or the element connection line 22 display may be performed (steps 06 to 16). Further, steps 18, 19, 28, and 29 are omitted, and the element connecting line 22 or the character connecting line 23 may not be deleted.

  Furthermore, the element connection line 22 and steps 11 to 16 may be omitted. Thereby, the character without the element connection line 22 and the character connection line can be displayed / hidden and compared. Further, when the display positions of the plurality of characters are individually changed, the character connecting line 23 may be displayed again from the beginning step by step or all at once. Thereby, each time the character spacing is changed, the character connecting line 23 is recalculated to form the optimum character connecting line 23. In this case, after the processing of steps 01 to 04, the character connection line display processing of steps 23 to 27 is entered.

  Furthermore, when the size of each of the plurality of characters is individually changed, the element connection line information or the character connection line 23 may be displayed again from the beginning step by step or all at once. Thus, each time the character size is changed, the element connecting line 22 or the character connecting line 23 is recalculated to form the optimum character connecting line 23. In this case, after the processing in steps 01 to 04, the element connection line display processing in steps 12 to 16 or the character connection line display processing in steps 23 to 27 is entered.

  Moreover, the said character (element and element connection line) and the character connection line demonstrated in the said example the example displayed on a display screen. However, the drawing image data may be printed out on a printer, transferred to another external device, or written and stored in various storage media.

  Furthermore, the character connecting line 23 and steps 21 to 27 may be omitted. As a result, the character element 21 without the character connection line 23 and the element connection line 22 can be displayed / hidden and compared.

  Thereby, the character displayed can be connected and the atmosphere like the character of a brush calligraphy penmanship can be put out. Since the characters (element 21, element connecting line 22) and the connecting line (character connecting line 23) extend in opposite directions along one tangent at each end point, they are smoothly connected. And while each end point is connected smoothly, the direction point can be changed and the magnitude | size of a curve can be changed. Moreover, even if the direction point is changed to change the curvature, the smoothness of the connection between the end points is maintained. Regardless of how the bending state of the connecting line (character connecting line 23, element connecting line 22) or element 21 changes, the direction point information only needs to be changed R, and the connecting line (character connecting line 23, element It is not necessary to change the allocation of each end point information to the connecting line 22) and the element 21, and it is possible to easily cope with the change of the bending state.

[3] Means for storing character information for drawing a plurality of characters in association with each character, and storing connection line information for drawing a connection line connecting one of the plurality of characters and the other The character information and the connecting line information include the end point information at a point where two of each character or each connecting line are connected, and the extension of one tangent line that touches the two of the character or connecting line at this end point. It consists of direction point information that determines the magnitude of the curvature of the same character or connecting line, and at this end point, both of the character or connecting line extend in the opposite direction along the direction of the one tangent line. The curvature increases as the direction point moves away from the end point, and the character information is read out according to a predetermined instruction to display a plurality of characters, and according to another predetermined instruction, A character display method comprising: reading out the connection line information and displaying a connection line connecting the plurality of displayed characters.

Since the characters (element 21, element connecting line 22) and the connecting line (character connecting line 23) extend in opposite directions along one tangent at each end point, they are smoothly connected. And while each end point is connected smoothly, the direction point can be changed and the magnitude | size of a curve can be changed. Moreover, even if the direction point is changed to change the curvature, the smoothness of the connection between the end points is maintained. No matter how the connecting line (character connecting line 23, element connecting line 22) or the bending state of the element 21 changes, it is only necessary to change the direction point information. The connecting line (character connecting line 23, element connecting) It is not necessary to change the allocation of the end point information to the line 22) and the element 21, and it is possible to easily cope with the change of the bending state.

[4] Each time a character is input, the connection line is displayed between the previously input character and whether the connection line is displayed or not displayed each time a character is input. The character display method according to claim 3, wherein the character is selected. This allows you to see the character linking line / element linking line as you enter each character, and to compare the state with and without the character linking line / element linking line. Each can be clearly identified and grasped, and is close to the actual writing brush / calligraphy / calligraphy, and is useful for the teaching of writing brush / calligraphy / calligraphy.
