The target is to display the estimated strokes as if they were touches.

  A character stroke is expressed using a TTF (True Type Font) of outline type font data (refer to Patent Document 1), and a stroke order display device that displays elements constituting a character image according to the stroke order (refer to Patent Document 2). ), There has been a patent for a matrix display device (see Patent Document 3) that can sequentially turn on the writing order of characters and the like.

JP 2008-76555 A Japanese Laid-Open Patent Application No. 09-244616 Japanese Laid-Open Patent Application No. 08-220982

However, in Patent Document 1, a stroke is constituted by a plurality of control points to which a regular order is assigned, a contour is displayed, and a stroke is expressed. No more expression can be performed. The elements constituting the image of the character stored in the screen are displayed according to the stroke order. Patent Document 3 displays the character by controlling the display timing of the matrix in hardware using the display matrix. The way is inflexible.

  The present invention is to solve such a conventional problem, and capture means for capturing the coordinate value of the outline of a document character string as point sequence data for each character stroke forming the document character string; Dividing means for dividing the outline of the captured point sequence data into cells, and screen display means for specifying the screen display start time of each cell of the document character string divided by the dividing device and displaying the strokes An object of the present invention is to provide a document handwriting display tool.

The screen display means identifies the cell number identified by the character number that identifies the character of the document character string, the stroke number that identifies the stroke, and the cell number that consists of the four points represented by the two row numbers and the two column numbers. The image processing apparatus includes an adjusting unit that fills a color and displays a document character string at a screen display start time specified for each cell.

The dividing means for dividing the inside of the outline into cells is characterized in that the inside of the outline is divided into square cells of rows and columns until it is necessary and sufficient to dynamically display the document character string.

The capturing means uses the stylus pen to place the document character string placed on the tablet as a set of point string data, and the coordinates of the contour line by the character string, the stroke number, and the point string number that identifies the point string It is characterized by taking in values.

The adjustment means sets the time obtained by dividing the estimated stroke display time of the entire document character string by the total number of cells and the display order assigned to the cell number as an initial value of the screen display start time for each cell, and starts the screen display. It is characterized in that the time can be arbitrarily finely adjusted.

The display order assigned to the cell numbers is characterized in that each cell is painted with a specific color to represent the screen display order. The present invention is configured as described above.

  The inside of the outline of the document character string is captured by the program as the character of a set of square cells finely divided with desired accuracy, the display order for each cell is specified, and the screen display start time for the display order for each cell By designating and displaying on the screen, it is possible to display strokes for the document character string.

That is, according to the present invention, it is as if a calligrapher of a famous calligrapher, such as Tachibana Yuse, Kukai, Musashi Miyamoto, Susumu Shiba, Yasuyuki Wang, Shinji Kaji, is written on the spot. In addition, it is possible to display the estimated handwriting with a touch full of realism.

It is a whole block diagram of a document stroke display tool. It is explanatory drawing of the whole flow of this tool. FIG. 10 is a diagram of the first to third division of the document character string “Happy New Year”. It is the figure of the 1st division | segmentation which expanded the stroke of the right shoulder "dot" of the character "O". It is the figure of the 2nd division | segmentation which expanded the stroke of the right shoulder "dot" of the character "O". It is the figure of the 3rd division | segmentation which expanded the stroke of the right shoulder "dot" of the character "O". It is explanatory drawing of the point sequence data function A. It is an example of point sequence data. It is explanatory drawing of the detail of the algorithm of a mesh division of a character meat. It is explanatory drawing of the algorithm of the cell division | segmentation of the type of character stroke different from FIG. This is an example of a relatively complex character stroke. Related to FIG. It is an example of a screen explaining display order specification. It is explanatory drawing of the screen display start time function B. FIG. It is an example of data of a screen display start time function.

  In order to express handwriting, the inside of the outline of the captured document character string is divided into square grids of 2 mm x 2 mm as the first cell division, for example, 2 is input, and gradually input to half, 1/4, and so on. Then, the division is repeated until the outline is fine enough to display the stroke. Note that the unit of length may be determined based on the size of the paper or document that captures the document character string, and the size of the display screen.

In this way, the division into the document character string is performed by the program after the first square cell length is input by the operator, the character is divided by the program, the character meat consisting of the cell is obtained, and the stroke is confirmed on the screen. Repeat subdivision with half halves until sufficient.
The document stroke display tool on the screen determines the number of contour line point sequence data in consideration of the size of the screen display, and the operator gradually determines the fineness of the grid.

  A document character string made up of point outline data of character outlines taken in advance from paper or takuboku is divided into square cells, and the character meat of the set of the cells is automatically captured by the program.

As shown in FIG. 1, the tool includes a keyboard 11, a computer 12, a memory 13, a mouse 14, a screen 15, a tablet 16, and a stylus pen 17.
The operator inputs a character number and stroke number from the keyboard 11, confirms the input on the screen 15, and operates the stylus pen 17 to coordinate the outline of the document character string 18 arranged on the tablet 16. The value is taken into the memory 13 via the computer 12. The mouse 14 is connected to the computer 12 by infrared rays and is used for designating the display order for the cells (detailed in paragraphs 67 to 76).

In particular, in the coordinate reading device 20, a circuit or the like necessary for coordinate reading is incorporated in the tablet 16, and the stylus pen 17 is operated with a suitable pressing force at a desired point on the outline of the document character string 18. Thus, the coordinate value of the point is read.
Reference numeral 10 denotes an origin for reading the coordinate value of the point on the outline of the document character string 18 described later.

The overall flow of the tool is shown in FIG. 2, and will be described with reference to the overall configuration diagram of FIG.
By taking the stylus pen 17 shown in FIG. 1, the outline data of the outline line of the document character string 18 set on the tablet 16 is fetched (S1). Next, the captured outline is displayed on the screen 15 of FIG. 1 (S2) to see whether the number of point sequence data is sufficient for the stroke display.

Next, the cell division is performed on the screen 15 (S3), and the character meat screen display (S4) is performed with the set of the cells existing inside the outline as the character meat. That is, the cells are filled with a specific color, for example, black. At this time, the screen display start times (described later) for the individual cells are the same, and the value of the screen display start time function is simply 0, that is, the screen display of the document character string 18 is performed all at once or instantaneously. The

Here, it is determined whether the outline as a character is maintained. That is, it is checked whether sufficient division accuracy (S5) is obtained for the stroke. If it is not sufficient, the document character string 18 is enlarged as necessary to further subdivide the cell division (S6).

When it is determined that sufficient division accuracy is obtained for the stroke, that is, when the outline of the document character string 18 is divided until it becomes smooth, the display order designation (S7) for the cell numbers is performed for all cells, and then The screen display (S8) is performed in the display order and at equal time intervals. Next, the screen display start time of each cell is adjusted (S9), and the stroke is confirmed on the screen 15 (S10). If the optimum stroke is not obtained (S11), the display order is designated again and the optimum stroke is obtained. If so, the process ends.

Handwriting display control is performed by designating the screen display start time of each cell according to the cell number consisting of 4 points represented by the character number, stroke number, two line numbers and two column numbers and the display order of the document character string 18. I will do it. A document character string 18 “Happy New Year” as shown in FIGS. 3A, 3B, and 3C will be described as an example.

In order to identify the character of the document character string 18, “Ming” is set as character number = 1, “K” is set as character number = 2, and the like. Furthermore, as a stroke number to identify the number of strokes of characters or kanji characters, the vertical line on the left side of the day is formed by the stroke number = 1, the horizontal line on the upper side of the day and the vertical line on the right side in the “Ming” character in the figure. The inverted L character is set as stroke number = 2 or the like.

By controlling the document character string 18 in units of character numbers and stroke numbers in this way, it is possible to adjust the strokes flexibly and flexibly, and the writing, writing, and weakness of the writing brushes, weakness, and shaking of the calligraphy It can be dynamically reproduced on the screen 15 as a twist / attenuation.

As shown in (A), (B), and (C) of FIG. 3, the origin of the X and Y coordinate values is the origin 10, and the coordinate reading device 20 of FIG. These figures show that the 1/2 lattice is becoming finer from (A) to (B) and from 1/2 (B) to (C).

FIG. 4 shows a division of the document character string 18 of FIG. 3 extracted from the right shoulder “dot” stroke of “O” and enlarged, and is divided into squares. 5 and 6 respectively divide the stroke of FIG. 4 into 1/2 and 1/4, and then repeat the division with 1 / n (n is a multiple of 2), and the appropriate detail that can be displayed by handwriting. It will be divided.

  A set of squares that do not protrude from the outline of the character is represented as character flesh, divided into appropriate division accuracy, specified on the screen display start time of each square of the character flesh, and painted in a specific color, for example, black , Expresses the stroke as if a calligrapher was writing on the spot.

  As shown above, the origin 10 shown in FIG. 3 is not changed, particularly with respect to the origin in FIGS. In relation to the grid points, row numbers are assigned from the upper left to the lower side, and column numbers are assigned to the right, 1, 2, 3,... N, but the origin is not located at the upper left of these figures. In addition, the X and Y axes → and ↓ in these figures only indicate the respective axes, and the intersection of the arrows is the local origin.

As described in part in paragraph 25, details of the outline drawing of a character stroke will be described.
In this tool, a point sequence data function A as shown in FIG. 7 is prepared, which consists of a character number as the first parameter, a stroke number as the second parameter, and a point sequence number as the third parameter. , Y coordinate values are taken into the function A as point sequence data.

  FIG. 8 shows an example of point sequence data. When capturing the dot sequence data of the outline of the character stroke (S1 in FIG. 2), the operator inputs the character number and the stroke number, the dot sequence number is assigned in sequence by the program, X and Y coordinate values are captured. In the example of FIG. 8, the point sequence number is a consistent number for each character number and stroke number, but of course, it may be a consistent number independent of the character number and stroke number.

  In this way, the point sequence data of the outline is captured into the point sequence data function A with appropriate fineness until the last character is displayed for each character and stroke, “... Congratulations”. Appropriate fineness depends on the size of the screen display, for example, the smaller the display screen, the smaller the number of point sequence data captured, and the larger the display screen, the greater the number of point sequence data captured. This means that the character string outline can be displayed smoothly in this way.

  When all the point sequence data as shown in FIG. 8 is taken in, an outline can be drawn by a point sequence data function as appropriate. This can be done arbitrarily for the entire document string, characters, and strokes.

When the outline drawing is completed, the division of the outline is divided into squares, and the details of the algorithm will be described with reference to FIG.
In the same way, the figure is a “point” on the right shoulder of the character “O”, and for the sake of simplicity, the number of point sequences is extremely reduced and the number of divisions is also reduced.

As shown in FIG. 3, the original is enlarged as the origin 10 as shown in FIG. 3, but the origin 10 does not always change no matter how large or how fine the division is.
Also in FIG. 9, the x coordinate value is indicated by an arrow from left to right and the y coordinate value is increased from top to bottom.

The point sequence data and the grid point data to be described below are sorted according to the X and Y coordinate values, and the grid points existing inside the character stroke are extracted. The set of squares is the character meat. With this character, the outline of the character string is divided to such a fineness that it can be displayed smoothly for stroke display.

Here, both will be described again from the viewpoint of grid point data with respect to point sequence data.
The point sequence data is the X and Y coordinate values identified by the point sequence number on the character outline, and the grid point data is the X and Y coordinate values of the points where the grid intersects. Take a number.

The point sequence data P1 to P5 is a sequence of points that are continuous in this order, and forms a closed curve constituting the outline of the stroke, and P1 to P5 are expressed as follows.
(XP1 YP1), (XP2 YP2), (XP3 YP3), (XP4 YP4),
(XP5 YP5)
Among these point sequence data, the minimum value is P1, that is, (XP1 YP1), but the maximum values are XP3 and YP4.
Thus, Pn is a call for point sequence data, and (XPn YPn) represents its coordinate value.

Next, the point sequence data and the grid point data are sorted by the X and Y coordinate values, respectively, but the grid points that are the target of the character flesh are the minimum and maximum values of the X and Y coordinate values of the point sequence data. You only need to target something in between. That is, only the lattice points surrounded by the thick lines P23, P26, P56, and P53 indicated by ● in FIG.
Pk, l represents the name of a grid point, k represents a row number, and l represents a column number.

Table 2 and Table 3 are obtained by sorting the dot sequence data and the grid point data narrowed down as the above-mentioned character meat candidates by the X and Y coordinate values, respectively.
The X coordinate values are sorted so that the coordinate values increase from left to right as described above, and grid data having the same X coordinate values are arranged in the vertical direction.
Similarly, the Y coordinate values are sorted so that the coordinate values increase from top to bottom, and the lattice point data having the same Y coordinate values are arranged in the horizontal direction.

Next, in the figure, the grid points existing inside the point sequence data are obtained, and the character flesh consisting of the cells existing inside the point sequence data is obtained.
In order to obtain the lattice points existing inside the point sequence data, it is only necessary to obtain the lattice points that are sandwiched between two upper and lower straight lines connecting two point sequence data adjacent to each lattice point.
Therefore, for the lattice points, the Y coordinate values of the two straight lines described above when X = 3, 4, 5, and 6 will be examined.
As described above, for convenience, the lattice numbers in the figure are used as the X coordinate value scale and the row numbers as the Y coordinate value scale.

The equation of the straight line passing through the two points m and n is y-Ypn = (Ypm-Ypn) (x-Xpn) / (Xpm-Xpn)
It can be expressed. Therefore, the equation of the straight line P1P2 is y-Yp2 = (Yp1-Yp2) (x-Xp2) / (Xp1-Xp2)
It becomes.

From the above straight line equation, the program logic first finds the straight line equations of the straight line P1P2 and the straight line P1P5, and when obtaining the Y coordinate value when X = 3, only (X2,3 Y2,3) is two straight lines. It can be seen that the grid points are sandwiched between.
Similarly, when the Y coordinate value when X = 4 is obtained for these two straight lines, it is understood that (X2,4 Y2,4) and (X3,4 Y3,4) are lattice points that are sandwiched between the two straight lines. .

Next, a determination is made regarding the lattice point of X = 5. For this purpose, a straight line equation of straight line P2P3 and straight line P5P4 is obtained, and a Y coordinate value when X = 5 is obtained, (X2,5 Y2,5) , (X3,5 Y3,5), (X4,5 Y4,5) are lattice points that are sandwiched between the two straight lines.
Further, the determination is made for the lattice point of X = 6. When the equation of the straight line of the straight line P2P3 and the straight line P3P4 is obtained and the Y coordinate value when X = 6 is obtained, (X3,6 Y3,6) It can be seen that X4,6 Y4,6) is a lattice point sandwiched between the two straight lines.

  This completes the determination of grid points existing inside the point sequence data, that is, the character meat. That is, the lattice points P2, 3 P2, 4 P2, 5 P3, 4 P3, 5 P3, 6 P4, 5 P4, 6 remain. Among these lattice points, two squares composed of P2, 4 P3, 4 P2, 5 P3, 5 and P3, 5 P4, 5 P3, 6 P4, 6 are configured as character flesh. . Only the lattice point P2,3 is excluded from the lattice point P3,3, and cannot be formed as a lattice point because it cannot form a cell, and is excluded at the end. As described above, in this division, character flesh consisting of two squares is generated.

  Incidentally, for example, a character image such as “ゝ” as shown in FIG. 10 is different from the logic described in FIG. In this way, when the Y coordinate value increases in the same stroke, the X coordinate value increases once and then decreases, or conversely, the logic when the X coordinate value decreases and then increases next is Different.

In FIG. 10, three points P6, P7, and P8 are added between the point sequence data P3 and P4 in FIG. 9 as described above. Similarly, these point sequences form a closed curve, and the outline of the stroke is displayed. Although constituted, these eight point sequence data are expressed as follows.
(XP1 YP1), (XP2 YP2), (XP3 YP3), (XP6 YP6), (XP7 YP7), (XP8 YP8), (XP4 YP4), (XP5 YP5)
Among these point sequence data, the minimum value is P1, that is, (XP1 YP1), and the maximum values are XP6 and YP7.

Next, when the point sequence data and the grid point data are sorted by the X and Y coordinate values, the target grid points are P2, 3 P2, 7 P6, 7 shown by ● in FIG. Only the lattice points surrounded by the thick lines P6, 3 need to be targeted, as shown in Table 4.

Table 5 and Table 6 are obtained by sorting the dot sequence data and the lattice point data narrowed down as the above-mentioned character meat candidates by the X and Y coordinate values, respectively. The sorting procedure is the same as before.

Hereinafter, only the parts different from the case of FIG. 9, that is, only the added point sequence data will be described. First, the cells forming the character flesh are added to the two cells shown in FIG. 9 by adding cells formed by lattice points P5, 6 P6, 6 P5, 7 P6, and 7. The program logic can basically be described so far, but it differs when there are a plurality of two straight line pairs sandwiching lattice points on the same x coordinate value (x = 5) line as shown in the figure. This is the logic for determining that a grid point indicated by a cross in the figure is excluded and that a grid point indicated by a circle exists inside the outline.

In the lattice point of X = 5, the lattice point sandwiched between the straight lines P5P4 and P8P4 must be excluded. The straight lines P8P4 and P8P7 are logics that determine that they exist inside the outline.

If the same examination is further advanced, it is a case of a relatively complicated character / character drawing as shown in FIG. In such a case, the determination of whether the lattice point is inside the character drawing (indicated by a circle) or the outside lattice point (indicated by a cross) is different from the processing described with reference to FIG.

As shown in FIG. 11A, when descending from the upper left to the lower right and eventually descending to the lower left, or similarly descending to the lower right and going to the upper left (not shown) Or, when going down from the upper right to the lower left and then going down to the lower right as in (B), or going down to the upper right and going up to the upper right (not shown) It is.

As can be seen from the figure, the determination is made by a pair of upper and lower two straight lines sandwiching the lattice points in the stroke. In (A), it is determined whether or not there is a grid point between the straight line 1 and the straight line 2, and then it is determined by the straight line 3 and the straight line 4. This means that the straight line 2 and the straight line 3 do not form a pair.
The same applies to (B), which means that determination is made based on the straight lines 5 and 6 and the straight lines 7 and 8. This means that the straight line 6 and the straight line 7 do not form a pair.
It is the same for strokes as shown in (C), and it is the same for strokes. The two straight lines sandwiching the grid points are judged by the first, second, third, fourth, fifth and sixth straight line pairs. It is. The second, the third, the fourth and the fifth are not the target straight line pair.
In FIG. 11, a straight line n is composed of two point sequence data adjacent to the lattice points, and a vertical line of X = 5 represents that a lattice point is formed with a horizontal line drawn horizontally. .

With such a logic, the division can be further divided into 1/2, 1/4, 1/8, etc., so that a smooth character stroke expression can be achieved. You can ask for meat.

  As previously explained in part, FIGS. 4, 5 and 6 show the division of the “s” character on the right shoulder of the character “O”. It is a figure explaining the process divided | segmented into a cell. Compared to FIG. 9, the point sequence data is increased from 5 points to 18 points, and the division is reduced to 1/2 and 1/4.

As a result, FIG. 5 further divides the cell of FIG. 4 in half, and FIG. 6 further divides the cell of FIG. In FIG. 4, the character flesh is represented by two squares, in FIG. 5, the character flesh is represented by 20 squares, and in FIG. 6, it is represented by 119 squares. The program logic for determining the character flesh described so far is effective no matter how fine the division is.

These explanations describe the logic of the program of this tool for the method of finding the character flesh by dividing the grid, focusing on the character “dot” on the right shoulder of the character “O”. ing. Once the division accuracy is sufficient for the stroke, the entire document character string as shown in FIG. 3 is divided at once to the division accuracy. At that time, the number of cells may be tens of thousands to hundreds of thousands, and in some cases, it can reach one million. Thus, the number of cells becomes enormous, and the sort data in each of the X and Y coordinate values described in paragraph 41 or 50 becomes the basic data of the program for obtaining the character flesh.

  When character meat consisting of square cells is obtained, these cells are assigned cell numbers by the program. The cell numbers are assigned with a consistent number from left to right and from top to bottom. In the case of a part of a character, that is, a character “dot” on the right shoulder of the character “O”, a cell number as shown in the figure is assigned to the square cell of the character.

First, in FIG. 4, character flesh is formed from two grids, and the grid numbers are configured by grid points as shown in Table 7.

FIG. 5 is more detailed than FIG. 4 and is divided into half the size of the cell, and the character flesh is formed from the 20 cells, and the cell number is composed of grid points as shown in Table 8. ing.

FIG. 6 is further finer than FIG. 5 and is divided into half cell sizes to form character flesh from 119 cells, and the cell numbers are composed of grid points as shown in Table 9. Here, intermediate cell numbers, that is, 4 to 116 and lattice points corresponding to the cell numbers are omitted, and only the three cells before and after are described.
Further, in FIG. 6, the lattices at the four corners forming the grids shown in FIGS. 4 and 5 are not shown as “k, l” (k is a row number, and l is a column number).

Even if the grid of FIG. 4 is made fine as shown in FIG. 6 and divided into quarter square grids, the division accuracy is still insufficient for proper handwriting display. In addition, the division in FIG. 6 is an explanation of the division of the “dot” on the right shoulder of the character “O”, and the number of cells when dividing the entire document character string, that is, “Happy New Year” is enormous. I mentioned earlier.

On the other hand, however, even after the point sequence data sufficient for stroke display is taken in, even if the division becomes finer and the number of cells becomes enormous, the above-mentioned program logic can mechanically obtain the character meat. . That is, as mentioned in paragraph 59, the sorting data of the X and Y coordinate values of the point sequence data and the grid point data is extremely important.

When it is determined that there is a sufficient number of characters for the stroke display, that is, the division accuracy is sufficient (S5 in FIG. 2), the display order is designated for the cell numbers (S7), and then displayed. The screens are displayed at regular time intervals (S8). Finally, adjustment of the screen display start time for each cell (S9) is performed.

A method of assigning the display order indicating the screen display order for each cell will be described. This will be described with reference to FIG. 12, which is a diversion of FIG.
The display order specification (S7 in FIG. 2) operation starts with the screen number assigned to each cell by the program displayed on the upper right in the cell as shown in FIG. 12 on the screen 15 in FIG.
In this way, the following operations are performed on the screen 15 using the mouse 14 and are performed by enlarging or reducing the figure shown in FIG. 12 displayed on the screen 15 as necessary.
When the mouse 14 is pressed in the cell number 1 and the cell 14 is pressed, the display order is 1, and this display order is displayed as an underlined number in the lower left of the cell.

Similarly, when the mouse 14 with the cell number 2 is pressed, the display order is 2, and when the mouse 14 with the cell number 11 is pressed, the display order is 3. By the same operation, the cell numbers 23, 3, 12, and 24 are assigned display orders 4 to 7 in this order. In this way, each cell is instructed one by one, and the display order is basically designated. However, the following semi-automatic method for continuously instructing the display order is provided.

When the mouse 14 with the cell number 4 is pressed, the display order is 8, and then the screen number is skipped and the display order is 11 when the mouse 14 with the cell 37 is pressed, and the program is stored in the skipped cell numbers 13 and 25. Judgment is made so that display orders 9 and 10 are entered.

Similarly, when the mouse number 14 of 21 is pressed, the display order is 49, and when the mouse 14 is pressed 87, the display order 56 is entered when the mouse 14 is pressed, and the cell number 33 From 79 to 79, the program judges and the display order 50 to 55 is entered.

In FIG. 12, the upper right P and lower left Q (with an underline) in the cell represent the cell number and display order currently described, that is, a specific numerical value is omitted without writing.

As described above, the number of cells sufficient for displaying the strokes may reach tens of thousands or millions. Therefore, in order to specify the display order for the cell numbers, other than such a method, a method of automatically assigning it by various programs is considered. Here, these methods will not be further described.

As described above, the character number, the stroke number, the grid number, and the display order are determined for all characters and strokes, that is, in the example of the present invention, for the character string “open”. Thus, the preparation for displaying the document character string on the screen 15 is completed.

For the screen 15 display, a screen display start time function B as shown in FIG. 13 is prepared, and the character number, stroke number, cell number, and display order that have been prepared so far are filled. .

When the total screen number it and estimated screen display total time t of the screen display start time for each individual cell, the screen display start time of each cell is t / it * i4 (i4 is the display order). Let's take a look at the strokes with the display start time as the initial value.

Assuming that the total number of cells “it” in FIG. 3 is 1 million (pieces) and the total screen display time t is 10 seconds, the screen display start time is 10 / 1,000,000 *. i4 (display order) = 10 μsec * i4
That is, each cell is painted in a specific color in the order of display at intervals of 10 μs, for example, black, and the screen 15 is displayed. That is, screen display (S8 in FIG. 2) is performed at the display order and at equal time intervals.

  When the confirmation of the display order is completed as described above, the screen display start time function B in FIG. 13, that is, the screen display start time of each cell is adjusted in order to approach the target stroke of the tool (see FIG. 2). S9) will continue.

FIG. 14 is a data example of the screen display start time function B. In this way, the screen display start time is adjusted for each character stroke. For example, the following subroutines are prepared in the stroke process described in paragraph 82 below. It is now convenient to be able to specify the screen display start time efficiently.
Details of these subroutines will not be described.

  After performing the stroke adjustment for each character or stroke, the final division of the document character string 18 “Opening ...” in FIG. 3 is finished, that is, for the right shoulder print “dot” of the character “O”, for example, 1 / When the stroke adjustment is confirmed in 512 divisions, and the stroke adjustment is completed for other strokes, the document character string 18 “open” is divided into 1/512 and the final confirmation is performed. Become.

Finally, the character string is displayed on the screen 15 of FIG. 1, and it is confirmed that it matches the estimated stroke display, and the expression (output) is completed. In this way, by adjusting the display order and the screen display start time with the characters and strokes, the strokes of the master call can be dynamically expressed in detail.

  Aiming at the complementary tool of Mr. Kyugo Ishikawa's “Modern Book History” that won the 2009 Great Buddha Jiro Award, words written in “Modern Book History” The present invention has been reached from the desire to be able to express handwriting dynamically.

Astrophysicist Ryo Ikeuchi described as a commentary on “The details of writing, brushing, brushing, twisting, damping, etc. For example, it is possible to dynamically express on the screen a concept such as “vertical brush, sense of speed, change in expression, feeling of pressure, etc.”.

Also, the characters and strokes are divided into cells, that is, the inside of the document character string outline is divided into fine cells, the stroke order is specified for each cell, and the screen display start time is set for each cell for which the stroke order is specified. By specifying, even “blur” can be expressed.

In addition, although it has been described that the square cell is divided into square cells, it is not always necessary to form a square cell. In short, it suffices to repeat the division with half of the square cell and further with the half of the square cell.
