Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character drawing device used for various information presenting devices and for drawing a character pattern corresponding to a given character code or character code string. .

[Conventional technology]

As a device for drawing a character, a device for storing and reproducing a character pattern as a dot pattern (hereinafter, referred to as a dot system), and a device for converting a character pattern into a dot pattern when extracting and storing the character pattern as vector data (hereinafter, referred to as a dot system) , Vector system). JP-A-62-
As disclosed in Japanese Patent No. 251983, "Character pattern generator", the latter vector system stores character outlines as vector data and fills the outlines when reproducing. It produces high quality characters. Storing a character pattern as a vector has the advantage that the character pattern can be easily enlarged or reduced. In particular, as a method of drawing a brush character pattern by a computer, "Generation of Kanji brush character by a computer" (Transactions of the Institute of Electronics, Information and Communication Engineers, May 1984, J67-D, No. 5,
As shown in pages 599 to 606), a method of drawing a brush character pattern by moving a brush touch pattern along a brush line has been studied.

Next, an example of a conventional character drawing apparatus using the vector system will be described. FIG. 71 is a block connection diagram showing a conventional character drawing apparatus disclosed in, for example, Japanese Patent Application Laid-Open No. 62-251983. In the drawing, reference numeral 181 denotes a stroke character storage unit from which corresponding stroke data is read by inputting a character code, 182 denotes a stroke drawing control unit which converts the stroke data read from the stroke character storage unit 181 into a dot pattern, and 183 denotes a stroke drawing control unit. A dot memory in which the dot pattern converted by the drawing control unit 182 is developed, 184 is a filling control unit that fills the inside of the outline of the character pattern read from the dot memory 183, and 185 is an overall control unit that controls the entire character drawing apparatus. It is a control unit.

Next, the operation will be described. Here, FIG. 72 is an explanatory diagram showing an example of the stroke data for character drawing in the character drawing apparatus thus configured, taking the alphabetic character "J" as an example. When a character code designating the alphabetic character “J” is input from outside, a series of stroke data 121 to 130 corresponding to the character code given from the stroke character storage unit 181 is extracted and sent to the stroke drawing control unit 182. Sent. The stroke drawing control unit 182 writes dots at corresponding points on the dot memory 183 according to the sent stroke data 121 to 130. When all dot patterns of a series of stroke data 121 to 130 corresponding to one character are drawn on the dot memory 183, the outline of the character pattern of the alphabet character "J" as shown in FIG. Is drawn. Next, the filling control unit 184 reads out the outline of this character pattern from the dot memory 183, fills out the area surrounded by the outline, and outputs a dot character output. These are sequentially controlled and processed by the overall control unit 185. When a character pattern is stored as a stroke vector, the character pattern can be easily enlarged and reduced.

[Problems to be solved by the invention]

Since the conventional character drawing device is configured as described above, since drawing is performed based only on character drawing data indicating a character shape, the time required for character drawing cannot be controlled,
In a vector-based character drawing apparatus, a character outline is drawn first, and then a closed area surrounded by the outline is painted out. It is determined by the processing algorithm of the processing unit and the drawing speed. On the other hand, in the dot type character drawing device, a character is displayed in the scanning order on the display device because the stored dot pattern is scanned and transferred to the image memory for drawing. Is determined by the data transfer speed.

Therefore, when drawing a stroke, the part that draws fast and the part that draws slowly are different from those when a person writes a character. Drawing of the next stroke starts. As described above, since the drawing speed and timing are considerably different from those in which a person writes characters, there is a problem that a person who observes the drawing process has a very uncomfortable feeling.

In addition, when drawing a character string, it is as if a person observing the displayed character string is interested in the character string and correctly understands the information having the character string, as if a human is character string. A method of displaying as if drawing is effective.
For example, when there is a character string to be emphasized, if each character constituting the character string is slowly written, the time to attract the attention of the person observing the character string becomes longer, and the observer's attention becomes longer. It has the effect of being easily remembered. Also, when a human draws a character string, after drawing of a certain character is finished, it takes a little time for the pen tip to move from the end point of the last stroke of the character to the start point of the first stroke of the next character. In short, during this time, a person observing the drawing of the character string can shift the point of gaze from the position of the previous character to the next drawing position, and can easily and concentrate reading the character string. .
However, the conventional character drawing device cannot control the time required to draw a character, and therefore cannot intentionally change the time required to draw a character. Is performed, there is a problem that the display effect that easily obtains the above-mentioned attention cannot be obtained.

The present invention has been made in order to solve the above-described problems, and adds pen speed information to character drawing data,
It is an object of the present invention to provide a character drawing device capable of drawing a character pattern at a speed according to the writing speed information.

Also, when drawing a character string, the inter-character time is set as information for controlling the time from drawing one character to drawing the next character, and drawing the next character after drawing one character. It is also an object of the present invention to obtain a character string drawing device capable of controlling the time until the start.

Then, by inputting the character string to be drawn and the entire character string drawing time, which is information for controlling the time required for drawing the entire character string, the character string is formed in accordance with a preset rule. A character drawing device capable of automatically calculating and setting the character drawing time and inter-character time of each character, and drawing the character string while controlling the time according to the set character drawing time and inter-character time. Is also an object of this invention.

The relative drawing time information of the character type determined in step 10 is selected from the character type drawing time table (step ST111), and the drawing required for drawing the character is determined based on the relative drawing time information and the preset standard drawing time information. The time is set (step ST42), and the drawing is executed while controlling the time according to the drawing time (step ST43).

In the above embodiment, the pattern information expressed by the dot method is used as the character drawing data, but the character drawing data is not limited to this.

In the figure, reference numeral 1b denotes a character drawing data storage unit that stores character drawing data necessary for drawing characters, and is composed of pattern information and handwriting information. The pattern information is information indicating the shape of each stroke constituting a character. The stroke information includes stroke order information indicating the drawing order of each stroke constituting a character, stroke direction information for each stroke, and stroke speed information that is information for controlling the time required for drawing between strokes and strokes. ing. Reference numeral 3b denotes a variable speed drawing processing unit, 4 denotes an image memory, and 5 denotes a display device for displaying the contents of the image memory 4.

Next, the data structure of the character drawing data used in this embodiment will be described with reference to FIGS. 13 and 14. FIG. Thirteenth
The figure shows an example of pattern information in the character drawing data of the alphabet "J". FIG. 13 (A) is a pattern information diagram, and FIG. 13 (B) is an explanatory diagram of an example of pattern information data. The pattern information stores the shape of each stroke constituting the character, and the shape of each stroke is represented by vector data indicating the outline. For example, "J" is composed of two strokes 201 and 202 as shown in the figure.
The first image 201 is a vector 210, 211, 212, 2 shown in FIG.
It is composed of 13 vectors. Each vector data is stored as a straight line code indicating a straight line as shown in FIG. 13 (B), and start point coordinates and end point coordinates defining the straight line. As an example of a curved portion, a contour line portion 216 of the second image is an arc code indicating that the portion is an arc, and coordinates (x7, y7) and (x8, y8) of three points defining the arc. , (X9, y9). FIG. 14 shows handwriting information in the character drawing data of "J", FIG. 14 (A) is a handwriting information diagram, FIG. 14 (B) is an explanatory diagram of handwriting information data example, and FIG. 14 (C). FIG. 7 is an explanatory diagram of a chain code string indicating a direction of stroke. The stroke information is composed of a stroke order indicating a display order of each stroke constituting the character, a stroke direction of each stroke, and a stroke speed which is information for controlling a time required for drawing each part of the character. . In FIG. 14, the stroke order is the first stroke and the second stroke. The stroke direction is stored for each stroke, and the starting point of the stroke, the end point of the last stroke, the coordinates of a point through which a stroke line connecting the start point and the end point passes, or direction data of the stroke line, etc. Is represented by For example, in FIG. 14A, the stroke line of the first stroke is a solid line 330 connecting the start point 331 and the end point 332, and the stroke line of the second stroke is a solid line 335 connecting the start point 336 and the end point 337. The direction of the stroke line is shown in "Digital Signal Processing" (translated by Professor Makoto Nagao, Professor, Kyoto University, pages 3-5) in the example of stroke information data shown in FIG. 14 (B). It is stored as a chain code string (FIG. 14 (C)). Next, the writing speed will be described. The stroke speed is the time required to draw each part of this character, that is, the time required to draw each part when dividing each stroke into a plurality of partial areas and drawing this partial area in order along the stroke line , 1
This is information for controlling the time from the end of drawing one stroke to the start of drawing of the next stroke. In the example of the stroke information data shown in FIG. 14, the stroke line of each stroke is divided into a plurality of partial areas by some speed change points, and the stroke speed is designated for each partial area. Further, the time from the end of drawing of one stroke to the start of drawing of the next stroke is stored as the inter-stroke time at the end of the stroke information of this stroke. The values of the stroke speed and the stroke time will be described later. For example, in the stroke information of the first stroke, the stroke line 33
0 is separated by two speed change points 333 and 334, and a partial area between the start point 331 corresponding to the writing portion of the stroke and the speed change point 333 is drawn at the stroke speed "1", and the transmission of the stroke is performed. The partial area between the speed change points 333 and 334 corresponding to the brush part is drawn at the stroke speed “3”, and the partial area between the speed change point 334 and the end point 332 corresponding to the stroke part of this stroke is It is specified to draw at the stroke speed “1”. Further, the time from the end of drawing of this stroke until the start of drawing of the next stroke is specified by the inter-stroke time “3”. The values of the stroke speed and the stroke time used in this embodiment will be described with reference to FIG. The stroke speed shown in FIG. 14 (B) is, for example, “1/30
This is a value indicating the width of an area to be drawn in a predetermined unit time, such as “second” or “20K clock in the clock cycle of the microprocessor of the drawing processing unit 3b”. here,
The size of a region does not mean only a mathematical area. For example, the area to be drawn may be divided into small areas that are sufficiently fine, and the number of the small areas may be used as the area size. In this embodiment, as shown in FIG. 15, first, the stroke line is finely divided at a predetermined constant interval, and the stroke pattern is divided by the normal line of the stroke line at each division point. Each divided small area is set as a unit area for drawing. The value described in the stroke speed indicates the number of unit areas to be drawn in a unit time. That is, according to the handwriting information of the first stroke in FIG. 14B, the area between the start point 331 and the speed change point 333 is drawn one unit area per unit time, and the speed change points 333 to 334 In the intervening area, three unit areas are drawn in unit time. The inter-drawing time indicates a time during which no drawing is performed after the drawing of the character is completed, and is stored in the unit time.

Next, the overall flow of the character drawing process according to this embodiment will be described with reference to FIGS. FIG. 16 is a flowchart of a character drawing process of the character drawing device according to this embodiment. First, in step ST161, the character code of the character to be drawn is input to the variable speed drawing processing unit 3b. Next, in step ST162, the variable speed drawing processing section 3b reads the pattern information and the handwriting information of the character corresponding to the character code from the character drawing data storage section 1b. Next, in the graphic drawing pre-processing of step ST163, a graphic drawing command sequence for drawing a character for each unit small area is generated based on the character drawing data. FIG. 17A is a detailed flowchart of the graphic drawing pre-processing, and FIG. 17B is an explanatory diagram showing an example of a graphic drawing command string generated by this processing.
In the graphic drawing preprocessing, the stroke pattern is divided into unit areas in step ST171. That is, first, the length of the stroke line included in the unit small area is set to L, and the stroke line is divided at an interval l from the start point to the end point or from the end point to the start point. Next, the normal line of the stroke line at each division point is determined. Then, an area surrounded by two normals at adjacent division points on the handwriting line and a contour of a stroke included between these normals is defined as one unit small area. Then step ST
In 172, first, for each divided small area, a figure drawing command for drawing this small area is generated, and these figure drawing commands are stored as a figure drawing command sequence arranged in order according to the stroke order and the stroke direction. I do. The figure drawing command for drawing one unit area includes outline data indicating the outline of the unit area by a chain code string, a fill command for instructing the fill inside the outline, and a drawing command inside the unit area. A flag indicating whether or not a speed change point or an end point is included.
Next, in the graphic drawing processing of step ST164 shown in FIG. 16, a character pattern is drawn in accordance with the graphic drawing command sequence generated in the graphic drawing pre-processing and the stroke speed information of this character. FIG. 18 is a detailed flowchart of the graphic drawing process in this embodiment. Hereinafter, the graphic drawing processing of the first image of the alphabet "J" will be described in detail with reference to FIG. First, in step ST701, the stroke speed is read from the stroke information data, and is set in a predetermined memory of the variable speed drawing processing unit 3b. In the case of this embodiment, the initial writing speed is "1" as shown in FIG. 14 (B). Next, in step ST702, a drawing number counter for counting the number of drawn unit areas and a timer for measuring a predetermined unit time are reset, and the timer is subsequently started. Next, in step ST703, a drawing command for one unit area is read and executed. Then, step
In ST712, the flag of this figure drawing command is checked, and if the flag is not set, step ST
At 713, "1" is added to the drawing number counter. Then, in step ST714, the counter value is compared with the writing speed value. If the counter value has not reached the writing speed value, the process returns to step ST703, and the unit area is drawn next. If the flag has been set in step ST712 and if the drawing number counter value has reached the writing speed value in step ST714, the process proceeds to step ST704 to check the timer value. If the timer value has not reached the preset unit time, step ST
At 705, a time wait is performed. When the timer value reaches the unit time, the flag of the unit area drawing command executed last in step ST706 is checked. If the flag has not been set, the process returns to step ST702, and the same number of unit areas as in the previous time are drawn within the unit time.
If the flag is set, it is checked in step ST707 whether the unit area includes the speed change point or the end point. If the speed change point is included, the process returns to step ST701, where the next stroke speed information is read from the stroke information and set in a predetermined memory. In the case of this embodiment, since the writing speed between the speed change point 333 and the next speed change point 334 is "3", "3" is set in the memory, and in step ST703, the unit area is set within the unit time. Are drawn three by three. If the end point is included in the last drawn unit area, the timer is reset and started in step ST708, and the next drawing is performed in step ST709 and step ST710 until the timer value reaches the stroke time specified in the handwriting information. Do not do. Finally, in step ST711, it is checked whether the last stroke is the last stroke of the character,
If it is not the last stroke, the process returns to step ST701 to start drawing the next stroke. If the last stroke drawn is the last stroke of this character, the process ends. By the above processing, the alphabet "J" can be drawn in the order from the start point to the end point of the stroke line along the stroke line.

The operation of the embodiment of the character drawing apparatus according to the present invention has been described above in detail. In the above embodiment, the stroke pattern is divided into unit areas by a predetermined method, and the number of unit areas to be drawn in a unit time is stored in the character drawing data storage unit as pen speed information. However, the writing speed information may be information indicating how much area of the character pattern is to be drawn and how long, and is not limited to the processing method of the above embodiment.

Next, another embodiment of the pen speed information (sixth embodiment)
And character drawing processing using the writing speed information will be described. FIG. 19A is a handwriting information diagram of character drawing data according to this embodiment, and FIG. 19B is an explanatory diagram showing an example of handwriting information data. The pattern information of the character drawing data uses the pattern information shown in FIG. 13 used in the above embodiment. The stroke information of FIG. 19 is, for each stroke constituting a character, the starting point coordinates of the stroke line of the stroke, the line data of each portion obtained by dividing the stroke line into a plurality of portions, and the stroke speed information of each portion. And the inter-drawing time for controlling the time from the drawing of the drawing to the start of drawing of the next drawing. The number of divisions as the writing speed information will be described later. For example, as shown in FIG. 19A, the stroke line 330 of the first stroke has the coordinates of the starting point 331 at (x21, y21) and is divided into three parts by two speed change points 333 and 334. ing. Therefore, as shown in FIG. 19 (B), in the stroke information of the first stroke, line data of each part of the stroke line divided at the speed change point is stored after the start point coordinates (x21, y21).
The line data of each part includes a straight line code indicating that the part is a straight line, the end point coordinates of the part, and the number of divisions of the part. Here, the division number as the writing speed information will be described. When the character drawing apparatus according to this embodiment draws a stroke pattern, the stroke is divided into a plurality of regions, and each region is drawn over a period of time specified by the stroke speed information. In the example, each area to be drawn at a constant stroke speed is further divided into a plurality of small areas, and the small areas are sequentially drawn one by one in the order along the stroke line within a designated time. The number of divisions is a value indicating whether an area to be drawn at a constant speed in a stroke is further divided into several small areas. And the graphic drawing processing unit,
Each of the divided small areas is drawn one by one within a unit time.

The overall flow of the character drawing process according to this embodiment is the same as that of the above-described embodiment shown in the character drawing process flowchart in FIG. Hereinafter, the graphic drawing pre-processing and the graphic drawing processing according to this embodiment will be described in detail with reference to FIGS. 20 to 23.

FIGS. 20 and 21 show an explanatory diagram and a flowchart of the graphic drawing preprocessing according to this embodiment. In the graphic drawing preprocessing, a character to be drawn is divided into small areas to be drawn in unit time, a figure drawing command for drawing each small area is generated, and the commands are accumulated in the order according to the handwriting direction. First,
In step ST211 in FIG. 21, the stroke pattern is divided into regions to be drawn at a constant stroke speed. That is, the nineteenth
As shown in FIG. 8B, the stroke of the first stroke is the speed change point 33.
It is divided into three parts by 3 and 334, and the number of divisions indicating the writing speed of the area including each part is “10”, “10”, and “10” in order from the starting point side. Therefore, as shown in the first image of FIG. 20, the stroke pattern is divided into three regions by the normals 391 and 392 of the stroke lines at the speed change point. The method of dividing the stroke pattern by a straight line passing through one point on the handwriting line is the same as the method of dividing the stroke pattern into unit small areas described in the above embodiment, and thus will not be described in detail here. Then, the processing of steps ST212 to ST214 in FIG. 21 is executed for each of the divided areas. In step ST212, the right contour line and the left contour line included in this area are each divided into the number of divisions which is the writing speed information of this area. Here, of the two outlines of the stroke separated by the start point and the end point of the stroke,
The outline on the right side in the handwriting direction is defined as a right outline, and the outline on the left is defined as a left outline. As shown in the first stroke of FIG. 20, the normal R ₀ L ₀ of the stroke 330 at the starting point 331 is a part of the outline of this stroke. In this case, the intersection of the normal line of the stroke line and the right side contour line of the strokes in the rate changes 333 R _10, the intersection of the left side contour line and L _10. Also, R ₀ R ₁₀ is a right outline included in this area, L ₀ L ₁₀ is a left outline, and R ₀ R ₁₀ and L ₀ L ₁₀ are each divided into ten equal points, which are sequentially numbered from the starting point side. I do. Then the steps in Figure 21
In ST213, as shown by the dotted line crossing the stroke line in FIG. 20, this area is divided into small areas by a straight line connecting the dividing points of the same number on the right outline and the left outline. The hatched portion in FIG. 20 is one small area. Next, in step ST214 in FIG. 21, a drawing command sequence for drawing each small area is generated, and this command sequence is stored in the working memory in the order according to the stroke direction. FIG. 22 shows an example of a graphic drawing command sequence. FIG. 22 (A) is the first of FIG.
This figure shows a part of the graphic drawing command sequence of the image.
The rectangle 90 includes a rectangle command indicating that the rectangle is a rectangle, coordinates of four points L ₀ , L ₁ , R ₁ , and R ₀ that define the rectangle, and a painting command that designates painting inside the rectangle. The columns in the case where the contour is a curve are shown in FIG.
In this embodiment, when the contour is a curve, the number of chain codes included in the chain code sequence representing the curve is defined as the length of the contour, and this is divided into the number of divisions which is the writing speed information. FIG. 22 (B) shows a graphic drawing command sequence of the small area 391 shown in the second image of FIG. Small Area 391
Are the curves R _n R _{n + 1} , L _n L _{n + 1} and the straight lines R _n L _n , R _{n + 1} L
_This is an area surrounded by _{n + 1} . In FIG. 22 (B), a curved line portion is represented by a point sequence command indicating that it is represented by a chain code sequence and a chain code sequence following the command. Small area
391 is a point sequence command and a chain code sequence indicating the curved line portion R _n R _{n + 1} , a straight line command indicating the straight line portion R _n L _n and the end point coordinates of the straight line, and a point sequence command of the curved line portion L _n L _{n + 1.} It is composed of a chain code string, a straight line command indicating a straight line portion Rn _{+ 1,} Ln _{+ 1} , the coordinates of the end point of the straight line, and a filling command for instructing the filling of an area surrounded by the four lines.

Next, the graphic drawing processing according to this embodiment will be described based on the detailed flowchart of the graphic drawing processing shown in FIG. In the graphic drawing process, a stroke pattern constituting a character is drawn in accordance with the stroke order stored in the stroke information. For each stroke, a graphic drawing command for drawing each small area stored in order according to the stroke direction is sequentially executed. That is, first, in step ST230 of FIG. 23, the timer for measuring the unit time is reset and subsequently started. Next, in step ST231, a figure drawing command for drawing one small area is executed, and this small area is drawn in the image memory. Next, in steps ST232 and ST233, time waiting is performed until the timer value reaches the unit time. When the timer value reaches the unit time, the process returns to step ST230 to execute drawing of the next small area. The processing from step ST230 to step ST233 is executed for all the small areas constituting the stroke. When the drawing of all the small areas constituting the stroke is completed, in step ST234 in the figure, the timer for measuring the stroke time is reset and subsequently started. Next, step ST235
Then, in step ST236, time is waited until the timer value reaches the inter-drawing time, and when the timer value reaches the inter-drawing time, the next stroke is drawn. The above processing is repeated until the drawing of all strokes is completed.

The operation of the embodiment of the character drawing apparatus according to the present invention has been described above in detail. In this way, the stroke pattern constituting the character is divided into a plurality of small areas, and the small areas are arranged in the order according to the handwriting information set in advance in the character drawing data, and at the speed specified by the handwriting speed information. Is drawn. By changing the drawing speed in the writing unit, the writing unit, and the sending unit of each stroke that constitutes a character, or after drawing one stroke,
The drawing speed can be controlled, for example, by taking one breath before the start of drawing the next stroke. In this way, by adding speed to the speed in character drawing, it is possible to perform drawing closer to the case where a human writes a character not only in the stroke order and the stroke direction but also in the stroke speed. No psychological burden on the observer. In particular, if the method is used for education or the like where the writing method is regarded as important, the same effect as when a teacher writes on a board can be expected. Also, in other information presentation systems, a good display effect can be obtained by using the character drawing device according to the present invention.

In the above-described embodiments, when drawing one character, in the pre-drawing process, the pattern is drawn from the pattern information and the handwriting information of the character drawing data in the unit small area or the small area in which the character is drawn in the unit time. A figure drawing command sequence for drawing each time is generated, temporarily stored in a work memory, and the figure drawing commands are sequentially executed in a figure drawing process. However, when a character string composed of a plurality of characters is to be drawn, the character drawing pre-processing for all the characters is collectively executed in advance, and the drawing command sequence and the unit time and the character The time information of the inter-time may be stored in a predetermined storage area or a storage device, and the graphic drawing processing may be collectively executed for all the characters.

Further, in the above embodiment, as the pattern information stored in the character drawing data, data of a vector system in which an outline is represented by a plurality of vectors is used. Any data can be used as long as the outline of the stroke can be developed in the work memory. For example, a method of directly storing the dot pattern of a stroke, or data obtained by chain-encoding the contour of a dot pattern may be used.

In the above two embodiments, in the graphic drawing pre-processing, the pattern information expressed in the vector system is temporarily expanded in the working memory, and thereafter, the stroke pattern is divided into a plurality of small areas and each small area is drawn. Is generated, but if the figure drawing command for drawing the outline of the small area or the small area can be directly obtained from the character drawing data, the pattern of the character drawing is stored in the working memory. No need to expand. For example, if the outline of each stroke is expressed by a straight line or a curved line, a region to be drawn within a unit time, such as the unit region used in the above-described embodiment or the small region used in the other embodiment, may be used. The contour can be directly obtained by calculation from a straight line formula or a curve formula.

The display device 5 is not limited to a CRT device,
A plotter, a storage tube type display, a liquid crystal display, or the like may be used as long as the device can display two-dimensional pattern information such as characters. Similarly, the image memory 4
The memory is not limited to a two-dimensional array memory such as a frame buffer, but may be any memory capable of temporarily storing sufficient information for displaying a two-dimensional pattern on the display device 5.

FIG. 24 shows, as character drawing data, stroke information indicating a display order of strokes constituting a character, stroke information defined by stroke lines defined for each stroke, pattern information indicating a character shape, and the character. FIG. 16 is a block diagram of a seventh embodiment including standard drawing time information and relative drawing time information when drawing.

FIG. 25 shows pattern information and handwriting information of character drawing data according to this embodiment. In this embodiment, the tables shown in FIGS. 25A and 25B are used as the pattern information and the handwriting information stored in the character drawing data storage unit 1c. The pattern information is information indicating the shape of each stroke constituting the character. Here, the outline of the stroke is described by some vector data. In addition, handwriting information,
In addition to the stroke order, the start point coordinates and the end point coordinates of the stroke line of the stroke and the stroke line connecting the start point and the end point are stored as information indicating the stroke direction for each stroke. Note that the stroke lines are represented by a chain code string shown on pages 2 to 5 of "Digital Signal Processing", Modern Science Co., Ltd. With reference to FIG. 26, a method of drawing a character pattern in the same stroke order and stroke method as when a person writes a character using such pattern information and handwriting information will be described.

FIG. 26 is a view for explaining the figure drawing process when the second image of the alphabet "J" is drawn according to the handwriting information. First, the pattern of the stroke is developed in the working memory according to the pattern information. Next, the stroke of the stroke is divided by a plurality of division points, and the stroke is divided into a plurality of small areas by the normal of the stroke at each division point. Then, the filled figure of each divided small area is drawn in the image memory 4 in order from the start point to the end point along the stroke line.

Here, the number of small areas in which a stroke constituting a character is divided and drawn is specified in the stroke information in advance for each stroke. For example, a method of calculating each division point is specified as coordinate data of each division point, or only the number of divisions is specified, and the strokes of the stroke are equally divided into the specified number of divisions in the character drawing process. is there. Here, as a division method, an interval 1 between division points is set in advance, and the stroke is divided from the start point to the end point in the character drawing process. In this case, when the length of the stroke line is L, the division number n of the stroke is n = L / l (rounded up below the decimal point).

Next, the standard drawing time information and the relative drawing time information in the character drawing data storage unit 1c in FIG. 24 will be described. As described above, the character drawing method used in this embodiment is a method in which a stroke constituting a character is divided into a plurality of small regions, and the small regions are drawn in order along a stroke line. Is obtained from the interval l between the division points and the length L of the stroke line of the stroke, and the number of divisions n = L / l. Then, the time required to perform the character drawing by this method without any time control is determined by the total time required to draw each small area. In this embodiment, the time required to draw one small area is set in advance as a unit drawing time. This allows
The time required to draw the character is determined by the product of the unit drawing time and the number of divisions. The standard drawing time is required for drawing the character when each stroke is divided at the dividing point interval set in advance in the handwriting information and each small area is drawn one by one in the unit drawing time set in advance. Time. Also, the relative drawing time is, when actually performing the character drawing, how many times the standard drawing time stored in advance in the character drawing data storage unit 1c is multiplied to draw the character. This is a value to be specified, and can be set at any time during the character drawing process.

As described above, since the time required for drawing the character is determined by the product of the unit drawing time and the number of divisions, the time required for drawing the character can be changed by changing the unit drawing time. . That is, assuming that the value of the given relative drawing time information is a, a value obtained by multiplying a preset unit drawing time by a may be used as the unit drawing time for the character drawing.

As another method of controlling the drawing time, there is a method of changing the number of divided strokes constituting a character by using a preset value for the unit drawing time. Hereinafter, a method of controlling the drawing time by changing the number of divisions will be described with reference to FIGS. 27 to 29.

FIG. 27 is a flowchart showing the overall flow of the character drawing process according to this embodiment. First, the character code of the character to be drawn is input (step ST271), and it is determined whether to reset the relative drawing time by referring to the standard drawing time of the character (step ST272). When resetting, the value of the relative drawing time is input from the input device, and the relative drawing time information stored in the drawing time information storage unit 22a is reset (step ST273). Next, character drawing data is input (step ST274), and a drawing command sequence for drawing the character in accordance with the handwriting information is created in advance (step ST274).
ST275), and executes drawing while controlling the time according to the relative drawing time (step ST275).

FIG. 28 is a drawing pre-processing in FIG. 27 (step ST27).
This is a flowchart of 5), and the figure drawing preprocessing will be described below. First, in accordance with the pattern information of the character drawing data, the pattern of the character to be drawn is developed in the working memory (step ST280), and then the division point interval is reset with reference to the relative drawing time information (step ST281). . That is, in the character drawing method according to the present embodiment, the time required to draw a character is the product of the unit drawing time and the number of divisions of the stroke constituting the character. The number of divisions is determined by the division point interval. The time required to divide and draw each stroke with the division point interval l set in advance in the handwriting information is the standard drawing time, and the relative drawing time is multiplied by many times the standard drawing time to draw the character. A value that specifies whether to render. Here, a preset division point interval l
Assuming that the division number at the time of dividing by n is n and the value set in the relative drawing time information is a, when actually drawing a character, the division number n ₁ of each stroke constituting the character is represented by n ₁ = a · n. As described above, the division number is determined by the length of the stroke line / division point interval. Since the length of the stroke line is constant, the division point interval is set to 1 / to increase the division number by a. It should be reset to a times.

Next, each stroke pattern constituting a character is described in step ST.
It is divided into small areas at the division point interval reset in 281 (step ST282), and finally, a figure drawing command sequence for drawing the filled figures of each small area in order along the handwriting direction is created (step ST283). .

Based on the graphic drawing command sequence created by the graphic drawing pre-processing described above, step ST27 shown in FIG.
In step 6, the filled figure of each small area is sequentially drawn in the image memory 4 while controlling the time. FIG. 29 is a flowchart of the graphic drawing process (step ST276) in FIG. First, the timer for measuring the drawing time is reset and subsequently started (step ST51). Next, one small area is drawn (step ST290), and the timer value is checked (step ST53). If the unit drawing time has not yet elapsed, time waiting is performed in steps ST54 and ST53, and after the unit drawing time has elapsed, it is checked whether or not the drawing of all the small areas has been completed (step ST291). In this way, the processing of steps ST51 to ST291 is repeated until the drawing of all the small areas is completed.

As described in detail above, according to this embodiment, using a character drawing data including pattern information and handwriting information, in a method of drawing a character in the same stroke order and handwriting direction as when a person draws a character, By providing the standard drawing time information and the relative drawing time information as the drawing time information so that the relative drawing time information can be changed at any time, the time required for drawing characters can be easily changed.

In the above-described embodiment, the standard drawing time information is provided and referred to when resetting the relative drawing time information. However, the standard drawing time information includes the pattern information and the handwriting information of the character drawing data and the drawing processing unit. It is a value determined by the performance of 34b, and need not be stored in the drawing time information storage unit 22a unless it is necessary to refer to it when setting the relative drawing time information.

Next, an eighth embodiment of the character drawing apparatus according to the present invention will be described with reference to FIGS. 14, 15, 30, and 31. FIG.

FIG. 30 is a block diagram showing a character drawing apparatus according to the eighth embodiment. In this embodiment, in drawing one character, a character drawing method capable of changing the writing speed depending on each part of the character is used. In this embodiment, by adding relative drawing time information, it is possible to change the time required for drawing one character while maintaining the speed of the stroke at the same rate.

In this embodiment, the character drawing data includes the pattern information shown in FIG. 14, the handwriting information, and the relative drawing time information. And the stroke speed, which is information for controlling the time required for drawing the image. The pattern information and the relative drawing time information are the same as those in the previously described seventh embodiment. First, FIG. 14, FIG. 15 and FIG.
This will be briefly described with reference to FIG.

In FIG. 14, the stroke order is the first stroke and the second stroke.
Next, the stroke direction is stored for each stroke, and is represented by a start point to be drawn first and an end point to be drawn last, and direction data of a stroke line connecting the start point and the end point. The stroke speed is calculated based on the time required when each stroke is divided into a plurality of partial regions and drawing the partial regions in order along the stroke line, and drawing of the next stroke after drawing of one stroke is completed. To control the time until the start of the process. In the example of the stroke information shown in FIG. 14, the stroke line of each stroke is divided into a plurality of partial areas by some speed change points 333, 334, 338, and 339, and the stroke speed is designated for each partial area. The stroke speed used in this embodiment is a value indicating how many unit small areas to be described later are drawn during a predetermined unit drawing time. Also, after drawing one stroke,
The time until the drawing of the next stroke is started is set as the inter-stroke time at the end of the stroke information of the stroke, and is expressed by the unit drawing time.

FIG. 31 is a flowchart of a character drawing process according to this embodiment. FIG. 31 (A) shows the overall processing flow. First, in FIG. 31 (A), a character code of a character to be drawn is input (step ST310), and relative drawing speed information is input. Here, the relative speed information is a value that specifies how many times the character drawing time required to draw a character based on only the pattern information and the handwriting information described above should be drawn. It is. Next, character drawing data of a character corresponding to the input character code is input (step ST311). Next, a figure drawing command sequence for drawing the character according to the stroke information is created (step ST312). FIG. 31 (B) is a flowchart of the figure drawing pre-processing (step ST312) in FIG. 31 (A), which will be described below. First, as shown in FIG. 15, the stroke line is finely divided at a predetermined fixed interval, and the stroke pattern is divided by the normal line of the stroke line at each division point (step ST171). Here, each divided small area is defined as a unit small area at the time of drawing. Next, a figure drawing command for drawing a filled figure of each unit small area is created, arranged in the order along the stroke direction, and stored (step ST172). After the above-described graphic drawing pre-processing is completed, the graphic drawing processing shown in FIG.
Perform 3). FIG. 31 (C) is a flowchart showing details of the figure drawing process. Since this flowchart is the same as the flowchart shown in FIG. 18,
The description of the operation is omitted.

As described above, when actually drawing a character, a drawing command for drawing each unit small area is sequentially read from the figure drawing command sequence created in the above-described figure drawing pre-processing, and the unit small size is read within the unit drawing time. Areas are drawn in the image memory 4 by the number specified for the pen speed. Further, when the drawing of one stroke is completed, the drawing waits for the time of the product of the value of the inter-stroke time stored at the end of the stroke information data of the stroke and the unit drawing time. Start drawing.

Here, the stroke speeds according to this embodiment are all controlled on the basis of the unit drawing time. In other words, the drawing speed of a stroke is expressed by the number of unit small areas to be drawn in the unit drawing time, and the inter-drawing time is expressed by a value indicating how many times the non-drawing time is longer than the unit drawing time. ing. Therefore, by changing the unit drawing time, the time required for drawing the entire character can be changed. That is, assuming that the value of the relative drawing time information is a, by multiplying the unit drawing time by a, it is possible to reduce the time of the character by a times the standard drawing time while maintaining the speed of the stroke of the character. You can draw by hanging.

As another time control method, there is a method of changing the number of divisions without changing the unit drawing time, or a method of changing the number of unit small areas to be drawn within the unit drawing time.
Hereinafter, a method of performing time control according to the relative drawing time information using these methods will be described.

In this character drawing method, the time required to draw the entire character is the time required to draw each partial area constituting the character, and the time between strokes from the end of drawing one stroke to the start of drawing the next stroke. And the sum of Therefore, if the value set in the relative drawing time information is X, if the time required to draw each partial area and the time between strokes are each multiplied by X, the time required to draw the entire character can be doubled. .

Therefore, the inter-drawing time is reset to a value obtained by multiplying the value of the inter-drawing time in the handwriting information data by the value set in the relative drawing time information before starting the graphic drawing processing.

Next, control of the drawing time of each partial area will be described. The time required for drawing each partial area is determined by the number of unit small areas constituting the partial area and the drawing speed when drawing the part. For example, in FIG.
The writing speed of the partial area between the starting point 331 of the first image and the speed change point 333 is "1", and the partial area is divided into six unit small areas as shown in FIG. Therefore, the time required for drawing the partial area is six unit drawing times. Also,
In the partial area between the speed change points 333 and 334 in FIG. 14 (A), the writing speed is “3” and the partial area is divided into 30 unit small areas. The time required is 10 unit drawing time.

Therefore, in order to make the drawing time of each partial area X times, the number of unit small areas constituting each partial area may be made X times. That is, in this character drawing method, the strokes are finely divided at a predetermined interval in the drawing pre-processing, and the stroke pattern is divided by the normal of the stroke at each division point. The time required to draw each partial region is X times by making the interval of dividing the stroke line 1 / X times.

Further, in order to make the drawing time of each partial area X times, the writing speed may be 1 / X times. For example, in the partial area between the speed change points 333 and 334 in FIG.
However, it is sufficient to set this to 3 / X. Where the pen speed is 1
The value multiplied by / X is not necessarily an integer. However, drawing of a unit small area can be performed only in integer units within a unit drawing time. Therefore, at the time of the graphic drawing process, a counter for counting the value indicated by the handwriting speed is provided, and the value indicated by the handwriting speed is added to the counter every time one unit drawing time elapses. Then, when the integer part of the counter value changes, the unit small area is drawn by the amount of the change. If the unit small area is drawn by the above method, the number of the unit small areas to be drawn in one unit drawing time fluctuates. You will draw a small area.

As described above, the seventh and eighth embodiments have described the examples of the character drawing apparatus that executes character drawing while performing time control using character drawing data other than the dot method. Here, as a method of setting the drawing time information in these character drawing apparatuses, a method of inputting from time to time from the outside to the drawing processing unit as in the case of the character code is used, as described in the sixth embodiment. In addition, a rule for controlling the drawing time may be stored in advance in the character drawing data using a table or the like, and the drawing time may be automatically changed according to the rule.

Next, a ninth embodiment of the present invention will be described with reference to the drawings.
In FIG. 32, 1a is a character drawing data storage unit,
Each character pattern information constituting the character string is stored.
Reference numeral 2b denotes a drawing time information storage unit, which stores character time information (hereinafter referred to as character time) which is information for controlling the time from drawing one character to drawing the next character. doing. 3a is a drawing processing unit, 4 is an image memory, 5 is a display device for displaying the contents of the image memory 4, and 8c is a drawing control unit including a drawing processing unit 3a and a character space control unit 7.

Next, the operation will be described. This will be described with reference to the flowchart of FIG. First, the drawing processing unit 3a inputs a character code string indicating a character string to be drawn and an inter-character time for drawing the character string (steps ST331 and ST332). number 3
FIG. 4 shows an example of a character code string used in this embodiment. In the figure, “9999” is a character string end code indicating the end of the character string. Here, each character constituting the character string is represented by a JIS kanji code, and a data string arranged in the order in which the JIS kanji codes of each character are displayed is input as a character code string. Further, in step ST332 in FIG. 33, as the inter-character time, a time t seconds from the end of drawing of a character at the time of drawing the above character string to the start of drawing of the next character is input. It is stored in the information storage unit 2b. Here, as a means for inputting the character code string and the inter-character time to the drawing processing unit 3a, a method in which a human inputs any time using an input device such as a keyboard can be considered. In addition, a method in which the data is filed in advance and the drawing processing unit 3a automatically reads the data from the data file, or a method in which the data is supplied from another application program may be considered.

Next, the inter-character control unit 7 reads the inter-character time from the drawing time information storage unit 2b, sets it at a position inside the drawing control unit 8c (step ST330), and measures whether the inter-character time has elapsed. Is reset (step ST333). Then, drawing processing section 3a executes drawing of the first character indicated by the character code string (step ST33).
Four).

In character drawing, first, pattern information corresponding to a character to be drawn is read from the character drawing data storage unit 1a,
A dot pattern is drawn in the image memory 4 according to the pattern information. In the present embodiment, pattern information expressed in a dot system is used as character drawing data. No.
Fig. 35 shows an example of the pattern of the alphabet "J".
The figure is an example of pattern information indicating the character. In the pattern information based on the dot method, the value of each point constituting the character as shown in FIG. 35 is stored as it is. That is,
Of the 16 × 16 points constituting the character in FIG. 35, the point of the character portion has a value “1”, and the portion other than the character has a value of “0”. The pattern information shown in FIG. 36 expresses this binary pattern in hexadecimal notation in the horizontal direction from the upper left. The drawing processing unit 3a reads the pattern information corresponding to the character code to be drawn from the character drawing data storage unit 1a and draws the pattern information on the image memory 4.

When the drawing of one character in step ST334 in FIG. 33 is completed, the drawing processing unit 3a determines whether or not the drawing of all the characters indicated by the input character code string is completed (step ST335). If not all the characters have been drawn, the inter-character control unit 7 starts a timer for measuring the inter-character time (step ST336), and waits for time in steps ST337 and ST338. When the time t seconds specified by the inter-character time has elapsed, the timer is reset again from step ST333, and drawing of the next character is started. Hereinafter, the processing of steps ST333 to ST338 is repeated until the drawing of all the characters indicated by the character code strings is completed.

In the above embodiment, one inter-character time is set for one character string, but the inter-character time between characters constituting the character string can also be set. Next, FIG. 37 and FIG. 38 show an embodiment of FIG.
This will be described with reference to the drawings.

FIG. 37 shows an example of a character code string and an inter-character time string to be input. In the drawing, “9999” is a character string end code. As shown in the figure, the inter-character time in the present embodiment is set to be one less than the number of characters constituting the character string, and is input in the order of drawing like the character string. According to the data in FIG. 37, the character string drawing apparatus according to the present embodiment first draws a character corresponding to the JIS code “3B30” and then stops the drawing process for two seconds indicated by the inter-character time. Then, the character corresponding to the JIS code "4929" is drawn. Then, stop for 2 seconds indicated by the next inter-character time data, draw a character corresponding to JIS code "4545", stop for 1 second indicated by the next inter-character time data, and stop the last character JI
The character string is drawn in the order of drawing the character corresponding to the S code “3521”.

FIG. 38 is a flowchart of the character string drawing process shown in FIG. According to this, first, a character code string and an inter-character time string are input (steps ST331 and ST332). Then, the first inter-character time is set (step ST380),
The timer is reset (step ST333). Next, the drawing of the first character is executed, and when the drawing is completed, it is determined whether or not the drawing of all the characters constituting the character string has been completed (step ST335). Step ST366), steps ST337 to ST338
In, a time is waited until the inter-character time set in step ST380 elapses. After the elapse of the time set in the inter-character time, the process returns to step ST380 to reset the next inter-character time and draw the next character. Hereinafter, step ST38
The processing from 0 to ST338 is repeated until the drawing of all the characters constituting the character string is completed.

In the above two embodiments, one inter-character time or one inter-character time sequence is input for one character string, and the character string is drawn according to the inter-character time. However, it is not always necessary to input the inter-character time or the inter-character time sequence for one character string. That is, the standard inter-character time is stored in the drawing time information storage unit 2b in advance, and the inter-character time or the inter-character time is set only when it is desired to set the inter-character time other than the time specified by the standard inter-character time. A column may be input. In the above two embodiments, the absolute value in units of seconds is input as a method of setting the inter-character time. However, the present invention is not limited to such a setting method, and the clock cycle of the microprocessor of the drawing processing unit 3a is not limited thereto. The number may be set as the inter-character time. In addition, the standard inter-character time is stored in advance in the drawing time information storage unit 2b, and indicates how many times the standard inter-character time is set as the inter-character time in actual drawing. A multiple may be input.

In the above embodiment, each inter-character time is set by inputting it from the outside. However, a rule for setting the inter-character time is stored in advance, and each inter-character time is automatically set in accordance with the rule. A setting method is also conceivable.

FIG. 39 shows an example of a character string drawing apparatus for automatically setting the inter-character time after drawing of a character according to the type of each character constituting the input character string (an eleventh embodiment). It is. In the figure, reference numeral 21b denotes a drawing time information storage unit, which stores a character type inter-character time table as shown in FIG. FIG. 40 shows an example of such a character type inter-character time table. In this embodiment, the types of characters are classified into seven types: symbols, English / numeric characters, hiragana, katakana, Greek characters, Russian characters, and kanji characters, and constitute character strings when drawing character strings. After drawing the character, the inter-character time is set differently depending on the character type of the character, and the time is controlled. FIG. 41 is a flowchart of a character string drawing process according to the present embodiment. In this embodiment, a code string is simply input from the outside in step ST331 of FIG. Then, one character is drawn first (step ST334).
Next, it is determined whether or not all the characters constituting the character string have been drawn (step ST335). If not, the type of the character drawn in step ST334 is determined from the character code (step ST334). ST413), and reads and sets the inter-character time corresponding to the character type of the character from the character type inter-character time table stored in the drawing time information storage unit 21b (step ST414). Then, the timer is reset and subsequently started (step ST415), and in steps ST416 and ST417, a time wait is performed until the inter-character time elapses. Hereinafter, the processing of steps ST334 to ST417 is repeated until the drawing of all the characters constituting the character string is completed.

In the eleventh embodiment, the inter-character time corresponding to each character type is stored as an absolute value in the inter-character time table of the character type shown in FIG. Time control is performed by using the time as it is when drawing the character string. Further, as another embodiment, a method of storing a relative value for specifying how many times the inter-character time corresponding to each character type of the character type inter-character time table with respect to the reference value of the inter-character time is stored. There is also. In this case, the reference value of the inter-character time is input together with the character code string from the outside, and the value obtained by multiplying the reference value by the table value corresponding to the character type of the drawn character at the time of drawing the character string is used as the actual character. The time is controlled as the time between.

In this embodiment, the character type character time table is used as a rule for setting the character time, but the rule is not limited to this. For example, the time between characters between alphabets or between numbers is half the time between characters, and the time between characters between Chinese characters is twice the time between characters. For example, a different time may be set as the inter-character time depending on a combination of character types of characters before and after the character. As another rule, the drawing time information storage unit
A method of calculating the inter-character time by storing a function in 21b and inputting necessary parameters from the outside and acting on the function may be considered.

The character string drawing processing by the character string drawing apparatus according to the present invention has been described in detail with reference to some embodiments. In the above embodiment, the pattern information expressed by the dot method is used as the character drawing data. However, the character drawing data is not limited to this. What is necessary is just enough information to draw in the memory 4. For example, instead of storing the value of each point constituting the character pattern as it is in the above-described embodiment, data that has been subjected to encoding such as run-length encoding may be used. Further, the outline of the character pattern may be represented by vector data, or vector pattern information in which each stroke constituting a character is represented by vector data may be used.
In addition, not only pattern information indicating the shape of a character but also character drawing data including information indicating the stroke order of the character, the stroke direction, stroke speed, and the like of each stroke may be used.

FIG. 42 shows a twelfth embodiment in which character drawing is performed with reference to the stroke information, such as the stroke direction and stroke speed, of such strokes stored in the character drawing data storage unit. In this figure, the stroke information includes a stroke order indicating the drawing order of each stroke constituting a character, a stroke direction for each stroke, and stroke speed information which is information for controlling the time required for drawing between strokes and strokes. include.

The pattern information is as shown in FIG. In other words, the pattern information stores the shape of each stroke constituting the character, and the shape of each stroke is represented by vector data indicating its outline. For example,
“J” is composed of two strokes 201 and 202 as shown in FIG. 13, and the first stroke 201 is composed of four vectors 210, 211, 212 and 213 shown in FIG. 25 (A). Each vector data is stored as a straight line code indicating a straight line as shown in FIG. 13 (B), and start point coordinates and end point coordinates defining the straight line. As an example of the curved portion, a contour line portion 216 of the second image is an arc code indicating that the portion is an arc, and coordinates (x7, y7) and (x8, y8) of three points defining the arc. , (X9, y9)
And is memorized.

The stroke information in the character drawing data of “J” is, for example,
It is as shown in FIG. The stroke information is composed of a stroke order indicating a display order of each stroke constituting the character, a stroke direction of each stroke, and a stroke speed which is information for controlling a time required for drawing each part of the character. . 14th
In the drawing, the stroke order is the first stroke and the second stroke.

Next, the stroke direction is stored for each stroke, and the starting point to be drawn at the beginning of this stroke, the end point to be drawn at the end, and the coordinates of a point through which a stroke line connecting the start point and the end point passes or the stroke of this stroke line It is represented by direction data and the like. For example, in FIG. 14A, the stroke line of the first stroke is a solid line 330 connecting the start point 331 and the end point 332, and the stroke line of the second stroke is a solid line 335 connecting the start point 336 and the end point 337. The direction of the stroke line is stored as a chain code string (FIG. 14 (d)) in the example of stroke information data shown in FIG. 14 (B).

Therefore, the operation for drawing one character is the same as the operation in the fifth embodiment.

In the same manner as in the fifth embodiment, 1
After drawing a character, the character spacing control unit 7 waits until the character spacing time stored in the drawing time information storage unit 2b elapses, and then starts the next character drawing.

FIG. 43 is a block diagram showing a thirteenth embodiment, which
The drawing time information storage section 2c stores the character drawing time information together with the inter-character time information in the drawing time information storage section 2b shown in FIG. 32. It is provided. In this embodiment, following the input of the character code string in step ST331 as shown in FIG. 33, the time T seconds required to draw one character is input, and after the drawing of one character is completed, The time between characters is input in step ST332 in FIG. 33, which controls the time until drawing of the next character is started.

In the character drawing process, first, as shown in the flowchart of FIG. 44, pattern information corresponding to a character to be drawn in step ST440 is read from the character drawing data storage unit 1a, and in step ST441, drawing time information is read. The character drawing time stored in storage unit 2c is read, and a unit drawing time is set based on the character drawing time (step ST442). Here, the unit drawing time is a value indicating the time required for one drawing process. In the character drawing process according to the present embodiment, a character pattern of 16 × 16 dots is drawn line by line, so that the drawing process is performed 16 times. That is,
The time required to draw a pattern for one line is the unit drawing time. Here, since the input character drawing time is T seconds, the unit drawing time is T / 16 seconds.

Next, the timer for measuring whether or not the unit drawing time has elapsed is reset and subsequently started (step ST443). Then, the drawing processing unit 34a draws a pattern for one line in the image memory 4 (step ST44).
Four). Further, in steps ST445 and ST446, the speed control unit 6 waits until the unit drawing time elapses. After the unit drawing time has elapsed, it is determined whether or not the pattern of all lines of the character has been drawn (step ST447). If drawing of all lines has not been completed, the process returns to step ST443 to draw the next line. Do. that's all,
The processes in steps ST443 to ST447 are repeated until the drawing of the pattern of all the lines of the character is completed.

When the drawing of one character is completed by the character drawing process described above, the drawing processing unit 34a proceeds to step ST335 in FIG.
It is determined whether or not drawing of all the characters indicated by the input character code string has been completed. If not all the characters have been drawn, the inter-character control unit 7 starts a timer for measuring the inter-character time (step ST336), and waits for time in steps ST337 and ST338. When the time t seconds specified by the inter-character time has elapsed, the timer is reset (step ST337), and drawing of the next character is started (step ST334). The above processing is repeated until the drawing of all the characters indicated by the character code string is completed.

In the above embodiment, one character drawing time and one inter-character time are set for one character string. The time between characters can also be set individually. Next, an embodiment (the 14th embodiment) in which the character drawing time of each character constituting the character string and the inter-character time between the characters can be set will be described with reference to FIGS. 45 and 46. explain.

FIG. 45 shows an example of a character code sequence, a character drawing time sequence, and an inter-character time sequence to be input. In the figure, “9999” is a character string end code. As shown in the figure, in this embodiment, the character drawing time is set for each character constituting the character string, and is input in the order of drawing like the character string. In addition, the inter-character time is set to be one less than the number of characters constituting the character string, and is input in a drawing order in the same manner as the character string. According to the data shown in FIG. 45, the character string drawing apparatus according to the present embodiment first converts a character corresponding to the JIS code “3B30” into a character drawing time of 5 seconds.
After drawing by multiplying by 2 seconds, the drawing process is stopped for 2 seconds indicated by the inter-character time, and then the character corresponding to JIS code "4929" is drawn by multiplying the next character drawing time by 5 seconds. Pause for 2 seconds indicated by the inter-character time data. Next, a character corresponding to JIS code "4545" is drawn in a character drawing time of 3 seconds.
Stop for 1 second indicated by the next inter-character time data, and draw the last character corresponding to the character JIS code “3521” for character drawing time 3
The corresponding character string is drawn in the order of drawing in seconds.

Next, the drawing of the first character is executed (step ST334). When the drawing is completed, it is determined whether or not the drawing of all the characters constituting the character string is completed (step ST335). It is set (step ST336), and in steps ST337 to 338, time waiting is performed until the inter-character time set in step ST462 elapses. After the elapse of the time set as the inter-character time, the process returns to step ST462 to reset the next character drawing time, and resets the next inter-character time in step ST460 to draw the next character. Hereafter, step ST
The processes of 462 to ST338 are repeated until the drawing of all the characters constituting the character string is completed.

FIG. 33 is a block connection diagram of the character drawing apparatus according to the sixteenth embodiment, including standard drawing time information for drawing the character in the time information storage unit 22c and relative drawing time information.

FIG. 51 shows the stroke information of the character drawing data according to this embodiment. In this embodiment, a table as shown in FIG. 13, FIG. 14, and FIG. 51A is used as the pattern information and the handwriting information stored in the character drawing data storage unit 1c. The pattern information is information indicating the shape of each stroke constituting the character. Here, the outline of the stroke is described by some vector data. In addition to the stroke order, the stroke information stores, as information indicating the stroke direction for each stroke, the start point coordinates and the end point coordinates of the stroke lines of the stroke, and the stroke lines connecting the start point and the end point. Note that the stroke lines are represented by a chain code string as shown in FIG. 51 (B). A method of drawing a character pattern in the same stroke order and stroke method as when a person writes a character using such pattern information and stroke information will be described with reference to FIG.

FIG. 52 is a view for explaining the figure drawing process when drawing the alphabet "J" in accordance with the second stroke information according to the handwriting information. First, the drawing processing unit 37b develops a stroke pattern in the work memory according to the pattern information. Next, the stroke of the stroke is divided by a plurality of division points, and the stroke is divided into a plurality of small regions by the normal of the stroke at the stroke division point. Then, the filled figure of each divided small area is drawn in the image memory 4 in order from the start point to the end point along the stroke line.

Here, the number of small areas in which a stroke constituting a character is divided and drawn is specified in the stroke information in advance for each stroke. For example, each division point is specified as coordinate data of each division point, or only the number of divisions is specified, and each stroke point is determined so that the strokes of the stroke are equally divided into the specified number of divisions in the character drawing process. There are ways. Here, as a division method, an interval 1 between division points is set in advance, and the stroke is divided at the interval from the start point to the end point in the character drawing process. In this case, when the length of the stroke line is L, the division number n of the stroke is n = L / l (rounded up below the decimal point).

Next, the standard drawing time information and the relative drawing time information in the drawing time information storage unit 22c in FIG. 50 will be described. As described above, the character drawing method used in this embodiment is a method in which a stroke constituting a character is divided into a plurality of small regions, and the small regions are drawn in order along a stroke line. Is obtained from the interval l between the dividing points and the length L of the stroke line of the stroke, and the number of divisions n = L / l. Then, the time required to perform the character drawing by this method without any time control is determined by the total time required to draw each small area. In this embodiment, the time required to draw one small area is set in advance as a unit drawing time. This allows
The time required to draw the character is determined by the product of the unit drawing time and the number of divisions. The standard drawing time is required for drawing the character when each stroke is divided at the dividing point interval set in advance in the handwriting information and each small area is drawn one by one in the unit drawing time set in advance. Time. The relative drawing time is determined by multiplying the standard drawing time, which is stored in advance in the character drawing data storage unit 1, by a certain time when the character is actually drawn. This is a value to be specified, and can be set at any time during the character drawing process.

As described above, since the time required for drawing the character is determined by the product of the unit drawing time and the number of divisions, the time required for drawing the character can be changed by changing the unit drawing time. . That is, assuming that the value of the given relative drawing time information is a, a value obtained by multiplying a preset unit drawing time by a may be used as the unit drawing time for the character drawing.

As another method of controlling the drawing time, there is a method of changing the number of divided strokes constituting a character by using a preset value for the unit drawing time. Hereinafter, a method of controlling the drawing time by changing the number of divisions will be described with reference to FIG.

FIG. 53 is a flowchart showing the flow of one character drawing process according to this embodiment. First, the character code of the character to be drawn is input (step ST531). next,
Referring to the standard drawing time of the input character, it is determined whether or not to reset the relative drawing time (step ST532). When resetting, input the value of relative drawing time from the input device,
The relative drawing time information stored in the drawing time information storage unit 22c is reset (step ST533). Next, pattern information is input (step ST534), and a drawing command sequence for drawing characters along the stroke information is created (step ST535).

The drawing pre-processing (step ST535) is as shown in the flowchart of FIG. 28, and the operation has been described above.

Based on the graphic drawing command sequence created by the graphic drawing pre-processing shown in FIG. 28, step ST53 shown in FIG.
In step 6, the filled figure of each small area is sequentially drawn in the image memory 4 while controlling the time. This figure drawing process (step ST536) is as shown in the flowchart of FIG. 29, and the operation has been described above.

As described above, according to this embodiment, the character drawing data including the pattern information and the handwriting information is used to draw characters in the same stroke order and handwriting direction as when a person draws a character. The time information storage unit 22c has standard drawing time information, relative drawing time information, and inter-character time, and the relative drawing time information can be changed at any time, so that the time required for drawing characters can be easily changed. Becomes

In the above embodiment, the character drawing data is provided with the standard drawing time information, and is referred to when resetting the relative drawing time information. However, the standard drawing time information is the pattern information and the handwriting information of the character drawing data. And a value set according to the performance of the drawing processing unit. If there is no need to refer to the relative drawing time information when setting it, the drawing time information storage unit 22
There is no need to store it in c.

Next, a seventeenth embodiment of the character drawing apparatus according to the present invention will be described with reference to FIGS. 54 and 31.

FIG. 54 is a diagram showing the structure of a character drawing apparatus according to the seventeenth embodiment. In this embodiment, in drawing one character, a character drawing method capable of changing the writing speed depending on each part of the character is used. In this embodiment, by adding relative drawing time information to the character drawing data, it is possible to change the time required to draw the entire character while maintaining the speed of the stroke at the same rate. In this embodiment, the character drawing data shown in FIG. 14 of the description is used. In FIG. 14, the stroke order is the first stroke and the second stroke. Next, the stroke direction is stored for each stroke, and is realized by a starting point to be drawn first and an end point to be drawn last, and direction data of a stroke line connecting the starting point and the end point.
The stroke speed is calculated based on the time required when each stroke is divided into a plurality of partial regions and drawing the partial regions in order along the stroke line, and drawing of the next stroke after drawing of one stroke is completed. To control the time until the start of the process. No.
In the handwriting information example shown in FIG. 14, the handwriting line of each stroke is divided into a plurality of partial areas by some speed change points 333, 334, 338, 339, and the handwriting speed is specified for each partial area. The stroke speed used in this embodiment is a value indicating how many unit small areas to be described later are drawn during a predetermined unit drawing time. Further, the time from the end of drawing of one stroke to the start of drawing of the next stroke is set as the inter-stroke time at the end of the stroke information of the stroke, and is expressed by the unit drawing time. I have.

A flowchart of a character drawing process for one character when drawing a character string according to this embodiment is as shown in FIG. 18 or FIG. Therefore, the operation is the same as the operation in the fifth embodiment or the eighth embodiment.

As described in detail in the fifth embodiment, when actually drawing a character, a drawing command for drawing each unit small area is sequentially read from the graphic drawing command sequence created in the above-described graphic drawing preprocessing, and the unit is read. The unit small areas are drawn in the image memory 4 by the number specified for the pen speed within the drawing time. Further, when the drawing of one stroke is completed, the drawing waits for the time of the product of the value of the inter-stroke time stored at the end of the stroke information data of the stroke and the unit drawing time,
After that, the drawing of the next stroke is started. Then, when drawing of all strokes is completed, the inter-character control unit 7 reads the inter-character time stored in the drawing time information storage unit 22c, waits for the inter-character time to elapse, and Start drawing characters.

Here, the stroke speeds according to this embodiment are all controlled on the basis of the unit drawing time. That is, the character drawing speed is expressed by the number of unit small areas to be drawn in the unit drawing time, and the character stroke time is expressed by a value indicating how many times the non-drawing time is longer than the unit drawing time. I have. Therefore,
By changing the unit drawing time, the time required for drawing the entire character can be changed. That is, if the value of the relative drawing time information is a, the unit drawing time is a
By multiplying the character, the character can be drawn in a time that is a times the standard drawing time, while maintaining the rate of the stroke of the character.

As another time control method, there is a method of changing the number of divisions while keeping the unit drawing time, or a method of changing the number of unit small areas to be drawn within the unit drawing time. Hereinafter, a method of performing time control according to the relative drawing time information using these methods will be described.

In this character drawing method, the time required to draw the entire character is determined by the time required to draw each partial region constituting the character, and the time required to start drawing the next character after drawing one character. It becomes the sum with the time between. Therefore, if the value set in the relative drawing time information is X, if the time required to draw each partial area and the time between strokes are each multiplied by X, the time required to draw the entire character can be doubled. .

Therefore, the inter-drawing time is reset to a value obtained by multiplying the value of the inter-drawing time in the handwriting information data by the value set in the relative drawing time information before starting the graphic drawing processing.

Next, control of the drawing time of each partial area will be described. The time required for drawing each partial area is determined by the number of unit small areas constituting the partial area and the drawing speed when drawing the part. For example, in FIG.
The writing speed of the partial area between the starting point 331 of the first image and the speed change point 333 is "1", and the partial area is divided into six unit small areas as shown in FIG. Therefore, the time required for drawing the partial area is six unit drawing times. Also,
In the partial area between the speed change points 333 and 334 in FIG. 14 (A), the writing speed is “3” and the partial area is divided into 30 unit small areas. The time required is 10 unit drawing time.

Therefore, in order to make the drawing time of each partial area X times, the number of unit small areas constituting each partial area may be made X times. That is, in this character drawing method, the strokes are finely divided at predetermined intervals in the drawing pre-processing, and the stroke pattern is divided by the normal of the stroke at each division point. However, at this time, the time required to draw each partial area is X times by making the interval of dividing the stroke line 1 / X times.

Further, in order to make the drawing time of each partial area X times, the writing speed may be 1 / X times. For example, in the partial area between the speed change points 333 and 334 in FIG.
However, it is sufficient to set this to 3 / X. Here, the value obtained by multiplying the stroke speed by 1 / X is not necessarily an integer. However, drawing of a unit small area can be performed only in integer units within a unit drawing time. Therefore, at the time of the graphic drawing process, a counter for counting the value indicated by the handwriting speed is provided, and the value indicated by the handwriting speed is added to the counter every time one unit drawing time elapses. When the integer part of the counter value changes, the unit small area is drawn by the number of changes. If the unit small area is drawn by the above method, the number of the unit small areas to be drawn in one unit drawing time fluctuates. You will draw a small area.

The example of the character string drawing device that executes character string drawing while performing time control using character drawing data other than the dot method has been described above. Here, as a method of setting the drawing time information in these character drawing devices, a method of inputting from the outside to the drawing processing unit at any time is used as in the case of the character code, but it is necessary to control the drawing time in advance. It is also possible to store the rules in a drawing information storage unit using a table or the like, and to automatically change the drawing time according to the rules.

Next, an eighteenth embodiment of the present invention will be described with reference to the drawings. In FIG. 55, reference numeral 1a denotes a character drawing data storage unit which stores pattern information and the like of each character constituting a character string. Reference numeral 2a denotes a drawing time information storage unit which stores a character drawing time, which is information for controlling a time required to draw each character constituting a character string. 3a is a drawing processing unit, 4
Reference numeral denotes an image memory, and reference numeral 5 denotes a display device for displaying the contents of the image memory 4. Reference numeral 6 denotes a speed control unit, 9 denotes a character string storage unit that stores a character string to be drawn, and 10 denotes the entire character string drawing time, which is information for controlling the time required to draw the entire character string. The whole character string drawing time storage unit for storing the character string and the whole character string drawing time
This is a drawing time allocation processing unit that automatically sets the character drawing time according to a preset rule.

Next, a character string drawing process according to this embodiment will be described with reference to FIGS. 55 to 58. FIG. 56 is a flowchart of a character string drawing process according to this embodiment. First, a character code string indicating a character string to be drawn and an entire character string drawing time which is information for controlling a time required to draw the entire character string are input (steps ST561 and ST562). FIG. 57 shows an example of a character code string used in the present embodiment, in which “9999” is a character string end code indicating the end of the character string. Here, each character constituting the character string is represented by a JIS kanji code, and a data string in which the JIS kanji codes of each character are arranged in the display order is input as a character code string. In addition, the 56th
In step ST562 in the figure, a time period T seconds for drawing the entire character string is input. Here, the means for inputting the character code string and the entire character string drawing time is not only a method of inputting as needed by a person using an input device such as a keyboard, but also storing these data in a file in advance, A method in which 3a automatically reads data from the data file or a method in which the data is supplied from another application program may be considered. Here, there is a restriction on the minimum value that can be set as the entire character string drawing time, and it differs depending on the contents of the rules when performing the drawing time allocation process. It must be longer than the time required to draw each constituent character.

Next, in the drawing time allocation process of step ST563 in FIG. 56, the character drawing time of each character constituting the character string is calculated from the character code string and the whole character string drawing time, and the drawing time information storage unit Store in 2a. FIG. 58 is an explanatory diagram of the drawing time allocating process of step ST564 for setting each character drawing time according to the rule 1 used in the present embodiment.
Here, FIG. 58 (A) is a rule used in the present embodiment, FIG. 58 (B) is a flowchart of a drawing time allocating process according to the present embodiment, and FIG. 58 (C) is a drawing time allocating process of the present embodiment. This is the drawing time information assigned by and stored in the drawing time information storage unit 2a. In the drawing time allocation processing according to the present embodiment, each character drawing time is calculated in accordance with the rule that each character drawing time is equally divided by each character constituting the character string. Hereinafter, the drawing time allocation process according to this rule will be described with reference to FIG. 58 (B). First, the number of characters constituting a character string to be drawn is counted (step ST581). Here, the number of characters is N. Next, a character drawing time, which is a time required for drawing each character, is calculated (step ST582). The character drawing time t of each character is a time obtained by equally dividing the entire character string drawing time. That is, t = T / N. Further, the character drawing time is set in drawing time information storage section 2a (step ST583). Through the above-described drawing time allocation processing, t seconds are all allocated to the character drawing time, which is the time required for drawing each character, and thereafter, the drawing processing unit performs processing for each character stored in the drawing time information storage unit 2a. The character string is drawn while controlling the time according to the drawing time. Hereinafter, steps ST564 to ST566 in FIG. 56 will be described.
Will be described with reference to FIG.

First, the character drawing time for drawing the first character is read from the drawing time information storage unit 2a and set (step ST56).
4) The first character indicated by the character code string is drawn with the character drawing time set in step ST564 (step ST565). The operation in step ST565 is as shown in the flowcharts of FIGS. 4 and 5. That is, the operation is the same as that of the first embodiment.

When the drawing of one character is completed, the character drawing processing unit determines in step ST566 of FIG. 56 whether or not the drawing of all the characters represented by the input character code string is completed.
If all characters have not been drawn yet, the process returns to step ST564 in FIG. 56 to start drawing the next character. The processing of steps ST564 to ST566 is repeated until the drawing of all the characters indicated by the character code strings is completed.

According to the above processing, the input character string can be drawn with an equal time for drawing each character and the input character string with the entire drawing time T.

Next, a drawing time allocation process using another rule is performed.
A nineteenth embodiment will be described. FIG. 59 is an explanatory diagram of a drawing time allocating process for setting each character drawing time according to rule 2 used in this embodiment. Here, FIG. 59 (A) is a rule used in the present embodiment, FIG. 59 (B) is a flowchart of a drawing time allocating process according to the present embodiment, and FIG. 59 (C) is a drawing time allocating process in the present embodiment. 59 (D) is a table used in the writing time allocation process according to the present embodiment. In the present embodiment, the character types are classified into seven types: symbols, English / numeric characters, hiragana, katakana, Greek characters, Russian characters, and kanji characters, and drawing is performed at different times depending on each character type. In the table of FIG. 59 (D), the value set for each character type is determined by taking a multiple of the character drawing time as a reference when drawing a character included in the character type. Is a value indicating whether to render. According to the drawing time allocation rule according to the present embodiment, the character drawing time is allocated with a weight as shown in FIG. 59 (D) depending on the type of the character to be drawn. That is, if the time allotted for drawing symbols, alphanumeric characters and numbers is x (reference character drawing time), 3x for drawing Hiragana and Katakana, 2x for drawing Greek and Russian characters, and 2x for drawing Chinese characters Allocates 5x times each.

Hereinafter, the drawing time allocation processing according to this rule will be described with reference to the flowchart of FIG. 59 (B). First, the number of characters constituting a character string to be drawn is counted (step ST581). Here, the number of characters is N. next,
Each character drawing time is calculated (step ST592). Here, the characters that constitute the character string are m _i (i = 1, 2, 3,..., N). When the value of the relative rendering time information of the corresponding table character type includes a character m _i and a _i, drawing time x which becomes the reference is determined by the following equation.

Then, the character drawing time of each character is obtained by multiplying x by the relative drawing time information value according to the character type of each character. Through the above processing, each character drawing time is obtained and stored in the drawing time information storage unit 2a (step ST583). The character string drawing processing after setting the drawing time information is the same as the character drawing processing in the eighteenth embodiment described with reference to FIGS. 56, 4, and 5. As a processing rule, a function given by a mathematical expression, a graph, or the like can be used instead of the table format as shown in FIG. 59 (D). That is, a certain function is stored in the drawing time allocation processing unit 11 in advance,
By inputting the entire character string drawing time and other necessary parameters to the function, the character drawing time of each character is calculated and set.

By the way, in the above-described embodiment, when a character drawing is executed in the drawing processing unit 3a, a character string is formed under the control of the speed control unit 6 according to the character drawing time stored in the drawing time information storage unit 2a. Are drawn over the specified character drawing time. However, depending on the data configuration of the character drawing data or the character drawing processing algorithm of the drawing processing unit 3a, it is impossible to perform character drawing while controlling the time until the character is completed as described above. May be possible. FIG. 60 is a diagram showing the relationship between the character drawing time assigned to each character and the period during which the drawing is actually progressing from the start of drawing the character until the completion of the character pattern. FIG. 60 (A) shows the case where time control is possible in the middle stage until the character is completed.
Indicates a case where time control is impossible in the middle of the process until the character is completed. In the figure, the shaded portion indicates the period during which the drawing of characters is actually in progress. In the case where time control is possible in the middle stage until the character is completed, as shown in FIG. 60 (A), the actual drawing period extends over the entire assigned character drawing time. If the time control cannot be performed, the actual drawing is performed continuously after the character drawing is started, and the character is completed in the time required for drawing the character regardless of the allocated character drawing time. . However, even in such a case, the entire character string drawing time T is allocated to the character drawing time of each character constituting the character string. The distribution method may be equal allocation or weighted allocation as illustrated in FIG. 59 (D). Since the drawing processing unit 3a cannot perform time control when drawing each character, the drawing processing unit 3a draws one character by taking the time required for drawing each character. Here, the drawing processing unit 3a does not start drawing the next character unless the character drawing time of a certain character has elapsed. Therefore, even if time control is not possible for character drawing,
Even after the time required to draw the character has been extended to complete the drawing of the character, the drawing of the next character does not start until the character drawing time set for the character has elapsed.

The embodiments of the character string drawing apparatus according to the present invention have been described above. Here, the rules of the drawing time allocation processing unit are as follows:
It may be stored in the drawing time allocation processing unit 11 in advance, or may be a method of externally reading a necessary control program or data of a table or the like as necessary when performing the drawing time allocation processing. .

In each of the above-described embodiments, the drawing time allocation processing is performed by the drawing time allocation processing unit 11 in accordance with only one preset rule. However, a method is also conceivable in which a plurality of rules are stored in advance, and those rules are switched and used according to an instruction given from the outside.

FIG. 61 shows a state in which a plurality of rules are stored in advance, and the drawing time allocation processing unit 11 selects the input drawing time allocation rule selection code from the plurality of stored rules. FIG. 39 is a block diagram of another embodiment (twentieth embodiment) of the character string drawing apparatus configured to execute a drawing time allocation process according to the selected rule. In FIG. 61, reference numeral 12 denotes a drawing time allocation rule storage unit, in which a plurality of rules are stored in advance. When drawing a character string, first, a drawing time allocation rule selection code is input together with the character string and the entire character string drawing time. The drawing time allocation processing unit 11 reads a rule corresponding to the input drawing time allocation rule selection code from the drawing time allocation rule storage unit 12, and executes a drawing time allocation process according to the rule. The method of drawing time allocation processing and the method of drawing a character string thereafter are the same as in the above embodiment.

In the above embodiment, the pattern information expressed by the dot method is used as the character drawing data. However, the character drawing data is not limited to this, and the character pattern corresponding to the input character code is displayed as an image. What is necessary is just enough information to draw in the memory 4. For example, instead of storing the value of each point constituting the character pattern as it is as in the above embodiment, data that has been subjected to encoding such as run-length encoding may be used. Further, the outline of the character pattern may be represented by vector data, or vector pattern information in which each stroke constituting a character is represented by vector data may be used. In addition, not only pattern information indicating the shape of a character but also character drawing data including information indicating the stroke order of the character, the stroke direction, stroke speed, and the like of each stroke may be used.

Further, in the above embodiment, the absolute time in seconds is input as the entire character string drawing time, and the character drawing time is set in the absolute value in seconds. However, the present invention is not limited to such a setting method. The number of clock cycles of the microprocessor of the drawing processing unit 3a may be set as the entire character string drawing time or the character drawing time. In addition, a standard character drawing time is set in advance, and the entire character string drawing time required when drawing a character string input in the standard character drawing time is set as the standard character string entire drawing time. A method is also conceivable in which a value indicating how many times the character string is drawn in order to draw the character string is input as information for controlling the whole character string drawing time. In this case, the drawing time allocation processing unit
In step 11, a value obtained by multiplying a preset standard character drawing time by an input value may be stored in the drawing time information storage unit 2a as each character drawing time.

FIG. 62 shows a character drawing data storage unit 1b including pattern information and handwriting information and a variable speed drawing processing unit 3b.
FIG. 27 is a block diagram illustrating a character drawing device according to a twenty-first embodiment. 8d is a drawing control unit having a variable speed drawing processing unit 3b and a speed control unit 6.

The schematic operation of the character drawing apparatus thus configured is described in the 56th
This is as shown in the flowchart of FIG. However, the operation in step ST565 is a one-character drawing operation using handwriting information. That is, the pattern information and the handwriting information have the formats already shown in FIGS. 13 and 14. Therefore, the one-character drawing operation is the same as the operation in the fifth embodiment shown in FIGS. With this configuration, the drawing time assigned to each character can be automatically set, and the speed at which one character is drawn can be made variable.

Next, a twenty-second embodiment of the present invention will be described with reference to the drawings. In FIG. 63, reference numeral 1a denotes a character drawing data storage unit which stores pattern information and the like of each character constituting a character string. Reference numeral 2c denotes a drawing time information storage unit, which stores information between a character drawing time, which is information for controlling a time taken to draw each character constituting a character string, and a time from when one character is drawn to when the next character starts drawing. The time between characters, which is information for controlling time, is stored. 34a is a drawing processing unit, 4 is an image memory, and 5 is a display device for displaying the contents of the image memory 4. Reference numeral 6 denotes a speed control unit, 7 denotes a character interval control unit, 9 denotes a character string storage unit that stores a character string to be drawn, and 10 denotes information for controlling a time required to draw the entire character string. The entire character string drawing time storage unit 11 stores the entire character string drawing time, and calculates the character drawing time and the inter-character time from the character string and the entire character string drawing time according to a preset rule. This is a drawing time allocation processing unit that is automatically set.

Next, a character string drawing process according to the present embodiment will be described with reference to FIGS. 63 to 66. FIG. 64 is a flowchart of a character string drawing process according to this embodiment. First, a character code string indicating a character string to be drawn and an entire character string drawing time which is information for controlling a time required to draw the entire character string are input (steps ST641 and ST642). FIG. 65 shows an example of a character code string used in the present embodiment.
Is a character string end code indicating the end of the character string. Here, each character constituting the character string is represented by a JIS kanji code, and a data string in which the JIS kanji codes of each character are arranged in the display order is input as a character code string. In addition, the 64th
In step ST642 in the figure, a time period T seconds for drawing the entire character string is input. Here, the means for inputting the character code string and the entire character string drawing time is not only a method of inputting as needed by a person using an input device such as a keyboard, but also storing these data in a file in advance and performing drawing processing. How the unit 34a automatically reads data from the data file,
A method of supplying these data from another application program is also conceivable. Here, there is a restriction on the minimum value that can be set as the entire character string drawing time, and it depends on the contents of the rules when performing the drawing time allocating process, but at least the drawing processing unit 34a converts the character string at the highest drawing speed. It must be longer than the time required to draw each constituent character.

Next, in the drawing time allocation process of ST643 in FIG. 64, the character drawing time and the inter-character time of each character constituting the character string are calculated from the character code string and the entire character string drawing time, and the drawing time is calculated. The information is stored in the information storage unit 2c. FIG. 66 is an explanatory diagram of the drawing time allocating process in step ST644 for setting each character drawing time and the inter-character time according to Rule 1 used in this embodiment. Here, FIG. 66 (A) is a rule used in the present embodiment, FIG. 66 (B) is a flowchart of a drawing time allocating process according to the present embodiment, and FIG. 66 (C) is a drawing time allocating process of the present embodiment. Draw time information storage unit assigned by
This is drawing time information stored in 2c. In the drawing time allocating process according to the present embodiment, each character drawing time and each character are set in accordance with the rule that all inter-character times are uniformly set to b seconds and the remaining time is equally divided by each character constituting the character string. Calculate the interval time. Hereinafter, the drawing time allocation process according to this rule will be described with reference to FIG. 66 (B). First, the number of characters constituting a character string to be drawn is counted (step ST661). Here, the number of characters is N. next,
The total time B required for the character time when the character string is drawn is calculated (step ST662). Assuming that the number of characters is N, the inter-character time is N-1 times, so the total inter-character time is B = (N-1) · b. Further, a character drawing time which is a time required for drawing each character is calculated (step ST663). The character drawing time t of each character is a time obtained by equally dividing the remaining time obtained by subtracting the total inter-character time from the entire character string drawing time. That is, t = (T−B) / N. Through the above-described drawing time allocation processing, t seconds are all allocated to the character drawing time, which is the time required to draw each character, and b seconds are all allocated to the inter-character time, and are stored in the drawing time information storage unit 2c in FIG. Is stored. Thereafter, the drawing processing unit 34a controls the speed control unit 6 and the character interval control unit 7 while receiving time control according to each character drawing time and character interval time stored in the drawing time information storage unit 2c. Performs column drawing. Hereinafter, step ST644 in FIG. 64
The character string drawing process will be described according to ST651.

First, the character spacing control unit 7 reads and sets the character drawing time for drawing the first character and the character spacing time from the drawing of the character to the start of the next drawing from the drawing time information storage unit 2c. (Steps ST644 and ST645), the timer for measuring whether the inter-character time has elapsed is reset (Step ST646), and the drawing processing unit 34a draws the first character indicated by the character code string in the speed control unit. 6, the program is executed with the character drawing time set in step ST644 (step ST647). The operation in step 647 is as shown in the flowcharts of FIGS. 4 and 5. That is, the operation in the first embodiment is the same.

When the drawing of one character is completed, the drawing processing unit 34a determines in step ST648 of FIG. 64 whether or not the drawing of all the characters indicated by the input character code sequence is completed.
If the drawing of all the characters has not been completed, the inter-character control unit 7 starts a timer for measuring the inter-character time (step ST649), and also returns to steps ST650 and ST6.
At 51, wait for time. When the time b seconds specified by the inter-character time has elapsed, the process returns to step ST644 in FIG.
Start drawing the next character. Steps ST644 to ST6
The process of 51 is repeated until the drawing of all the characters indicated by the character code string is completed.

With the above processing, the input character string can be drawn while taking the inter-character time for every preset b seconds and the input character string entire drawing time T.

Next, a drawing time allocation process using another rule is performed.
Twenty-third embodiments will be described. FIG. 67 is an explanatory diagram of a drawing time allocating process for setting each character drawing time and inter-character time according to Rule 2 used in this embodiment. Here, FIG. 67 (A)
Is a rule used in this embodiment, FIG. 67 (B) is a flowchart of a drawing time allocation process according to this embodiment, and FIG. 67 (C).
Is drawing time information allocated by the drawing time allocation process of the present embodiment and stored in the drawing time information storage unit 2c.
In the drawing assignment processing according to the present embodiment, the character drawing time is set to a times the inter-character time, and each character drawing time is equally set.
Each character drawing time and character time are calculated according to the rule that the time between characters is equally allocated. Less than,
The drawing time allocation process according to this rule will be described with reference to the flowchart in FIG. 67 (B). First, the number of characters constituting the character string to be drawn is counted (step
ST661). Here, the number of characters is N. Next, the inter-character time is calculated (step ST672). According to rule 2, the character drawing time is a times the inter-character time, and the time between characters and the character drawing time are evenly allocated. Therefore, as shown in FIG. The rendering time is ab. Since the entire character string drawing time is T, T = N · ab + (N−1) · b, and the inter-character time b is calculated from b = T / (aN + N−1). Next, each character drawing time t is obtained by t = ab, and each character time and character drawing time are stored in the drawing time information storage unit 2c (step ST673). The character string drawing processing after the setting of the drawing time information is the same as the character drawing processing in the twenty-second embodiment described with reference to FIGS. 64, 4, and 5.

Twenty-fourth to perform drawing time allocation processing using still another rule
An example will be described. FIG. 68 shows rule 3 used in this embodiment.
FIG. 9 is an explanatory diagram of a drawing time allocation process for setting each character drawing time and the inter-character time according to FIG. FIG. 68 (A) is a rule used in the present embodiment, FIG. 68 (B) is a flowchart of a drawing time allocation process according to the present embodiment, and FIG. 68 (C) is a drawing time allocation process according to the present embodiment. Drawing time information stored in the drawing time information storage unit 2c, and FIG. 68 (D) is a table used in the drawing time allocation processing according to the present embodiment. In the present embodiment, the character types are classified into seven types: symbols, alphabets, numbers, hiragana, katakana, Greek characters, Russian characters, and kanji characters, and drawing is performed at different times depending on each character type. In the table of FIG. 68 (D), the value set for each character type takes a certain number of times as long as the character drawing time used as a reference when drawing characters included in the character type. Is a value indicating whether to render. According to the drawing time allocation rule according to the present embodiment, b seconds are equally allocated to the time between characters. For the character drawing time, a time is assigned with a weight as shown in FIG. 68 (D) depending on the type of character to be drawn. That is, assuming that the time allocated to drawing symbols and alphanumeric characters is X (character drawing time to be a reference), 3x for drawing Hiragana and Katakana, 2x for drawing Greek and Russian characters, and 2x for drawing Chinese characters Allocates 5x times each.

Hereinafter, the drawing time allocation process according to this rule will be described with reference to the flowchart in FIG. 68 (B). First, the number of characters constituting a character string to be drawn is counted (step ST661). Here, the number of characters is N. next,
The total character time B is calculated (step ST682). Next, each character drawing time is calculated. Here, the characters that constitute the character string are m _i (i = 1, 2, 3,..., N). The table corresponding to the character type that contains text m _i the value of the relative rendering time information
Assuming a _i , the reference drawing time x is obtained by the following equation.

Then, the character drawing time of each character is obtained by multiplying the above x by the relative drawing time information value according to the character type of each character (step ST683). By the above processing, the character drawing time and the inter-character time are obtained and stored in the drawing time information storage unit 2c. The character string drawing processing after setting the drawing time information is described in FIG. 64,
This is the same as the character drawing process in the twenty-second embodiment described with reference to FIGS.

Also, a function can be used as another rule of the drawing time allocation process. That is, a certain function is stored in the drawing time allocation processing unit 11 in advance, and the character drawing time and the inter-character time of each character are calculated by inputting the entire character string drawing time and other necessary parameters into the function. And set.

By the way, in the above embodiment, when performing the character drawing in the drawing control unit 83c, each character constituting the character string is designated according to the character drawing time stored in the drawing time information storage unit 2c. Is drawn over.
However, depending on the data configuration of the character drawing data or the character drawing processing algorithm of the drawing processing unit 34a, as described above, it is not possible to perform character drawing while controlling the time until the character is completed. May be possible.
In such a case, in order to draw the character string by taking the time specified by the entire character string drawing time, it is necessary to adjust the inter-character time. That is, the remaining time obtained by subtracting the total time required to draw each character from the entire character string drawing time may be assigned to each character time. Also, the time required to draw each character constituting the character string is determined by the drawing time allocation processing unit 11.
If it is not understood, a method of time control for drawing the character string over the time specified by the entire character string drawing time will be described below. First, all inter-character times are set to 0. Then, the entire character string drawing time T is allocated to the character drawing time of each character constituting the character string. The distribution method may be equal allocation or weighted allocation as illustrated in FIG. 68 (D). Since the drawing processing unit 34a cannot perform time control when drawing each character, the drawing processing unit 34a draws one character by taking the time required for drawing each character. Here, the drawing processing unit 34a does not start drawing the next character unless the character drawing time of a certain character and the inter-character time following it have elapsed. Therefore, even if time control is not possible for character drawing,
Even after the time required for drawing the character is over and the drawing of the character is completed, the drawing of the next character is not started until the character drawing time set for the character and the subsequent inter-character time have elapsed. In this case, (set character drawing time)-(time required for character drawing) becomes an apparent inter-character time, and as a result, the entire character string input time is multiplied by the drawing time. The character string will be drawn.

Here, the rule of the drawing time allocation processing may be stored in the drawing time allocation processing unit 8 in advance as a control program of the drawing time allocation processing unit 11, or may be necessary when executing the drawing time allocation processing. A method may be used in which data such as a simple control program or a table is externally read as needed.

In each of the above-described embodiments, the drawing time allocation processing is performed by the drawing time allocation processing unit 11 in accordance with only one preset rule. However, a method is also conceivable in which a plurality of rules are stored in advance, and those rules are switched and used according to an instruction given from the outside.

FIG. 69 shows a state in which a plurality of rules are stored in advance, and a rule corresponding to the input drawing time allocation rule selection code is selected from a plurality of stored rules in the drawing time allocation processing unit 11. FIG. 39 is a block diagram of another embodiment (a twenty-fifth embodiment) of the character string drawing apparatus configured to execute a drawing time allocation process in accordance with the selected rule. In FIG. 69, reference numeral 12 denotes a drawing time allocation rule storage unit in which a plurality of rules are stored in advance. When drawing a character string, first, a drawing time allocation rule selection code is input together with the character string and the entire character string drawing time. The drawing time allocation processing unit 11 reads a rule corresponding to the input drawing time allocation rule selection code from the drawing time allocation rule storage unit 12, and executes a drawing time allocation process according to the rule. The method of drawing time allocation processing and the method of drawing a character string thereafter are the same as in the above embodiment.

In the above embodiment, the pattern information expressed in the dot system is used as the character drawing data. However, the character drawing swing data is not limited to this, and a character pattern corresponding to the input character code may be used. It is sufficient if the information is sufficient for drawing in the image memory 4. For example, instead of storing the value of each point constituting the character pattern as it is as in the above embodiment, data that has been subjected to encoding such as run-length encoding may be used. Further, the outline of the character pattern may be represented by vector data, or vector pattern information in which each stroke constituting a character is represented by vector data may be used. In addition, not only pattern information indicating the shape of a character but also character drawing data including information indicating the stroke order of the character, the stroke direction, stroke speed, and the like of each stroke may be used.

In the above-described embodiment, the absolute time in seconds is input as the entire character string drawing time, and the character drawing time and the inter-character time are set in absolute values in seconds. However, the present invention is limited to such a setting method. Instead, the number of clock cycles of the microprocessor of the drawing processing unit 3 may be set as the entire character string drawing time, the character drawing time, or the inter-character time. In addition, a standard character drawing time is set in advance, and the entire character string drawing time required when drawing a character string input with the standard character drawing time and the standard inter-character time is calculated. As a time, a method of inputting a value indicating how much time is required to draw the character string with respect to the standard whole character string drawing time as information for controlling the whole character string drawing time is also conceivable. In this case, the drawing time allocation processing unit 11
May be stored in the drawing time information storage unit 2c as a value obtained by multiplying a preset standard character drawing time and inter-character time by the input value as the respective character drawing time and inter-character time.

FIG. 70 is a block diagram showing a character drawing apparatus according to a twenty-sixth embodiment having a character drawing data storage section 1b containing pattern information and handwriting information and a variable speed drawing processing section 37b. Reference numeral 85c denotes a drawing control unit having a variable speed drawing processing unit 37b, a speed control unit 6, and a character space control unit 7.

The schematic operation of the character drawing device thus configured is described in the 64th
This is as shown in the flowchart of FIG. However, the operation in step ST647 is a one-character drawing operation using handwriting information. That is, the pattern information and the handwriting information are in the format already shown in FIGS. 13 and 14. Therefore, the one-character drawing operation is performed in accordance with the operation shown in FIG. 16 to FIG.
The operation is the same as that in the embodiment. With this configuration, the drawing time assigned to each character can be automatically set, and the speed at which one character is drawn can be made variable. In addition, the time between characters can be appropriately set.

〔The invention's effect〕

As described above, according to the invention described in claim (1), at least the pattern information indicating the shape of the character and the character drawing time information indicating the time required to draw the character are used as the character drawing data. The drawing processing unit and the speed control unit are configured to draw the dot pattern indicated by the pattern information while controlling the time according to the character drawing time information. The time required for drawing can be easily controlled, so when drawing multiple characters, make the drawing speed slower, such as drawing some characters at high speed and drawing some characters slowly. Can be easily performed, thereby obtaining an effect that can attract the attention of a person who is watching the drawing of those characters or give a deep impression. In particular, there is an effect that in a place of education or presentation, a display which can perform good display can be obtained.

According to the invention described in claim (2) and claim (3),
Since the inter-character time information is stored in the drawing time information storage unit and the drawing processing unit and the inter-character control unit draw the character string according to the information, the character string is drawn when the character string is drawn. It is possible to stop the drawing process for a specified time from the time when the drawing of a character constituting the character is completed to the time when the drawing of the next character is started, and is also stored in the drawing time information storage unit. By simply changing the inter-character time information, there is an effect that an inter-character time when a character string is drawn can be easily controlled. In the case where a plurality of character strings are to be drawn by controlling the inter-character time, a certain character string is drawn at a high speed by setting a short inter-character time, and a certain character string is set to a long inter-character time. It is easy to make the drawing speed slower, such as by drawing slowly, so that a good display that attracts the attention of the person who is looking at the drawing of those characters and gives a deep impression can be done There is an effect that something can be obtained. Further, since the inter-character time information is stored for each type of character or for each character constituting a character string, there is an effect that the degree of attention of the character can be finely expressed for each type of character.

According to the invention described in claim (7), the inter-character time information and the character drawing time information are stored in the drawing time information storage unit,
Since the character string is drawn by the variable speed drawing processing unit that refers to the handwriting information, the speed control unit that regulates the drawing time of each character, and the character interval control unit that determines the drawing interval between characters, There is an effect that the speed at which the drawing speed in characters can be easily adjusted in units of one character and between characters can be easily obtained.

According to the invention of claim (8), a character string to be drawn and character string whole drawing time information, which is information for controlling the time required for drawing the whole character string, are input to the drawing time allocation processing unit. The character drawing time and the inter-character time of each character constituting the character string are automatically calculated according to a preset rule, and are stored in the drawing time information storage unit. In addition, since the drawing processing unit draws a character string in accordance with these pieces of information, it is not necessary to calculate the character drawing time of each character constituting the character string when drawing a character string. Therefore, in the case of drawing a plurality of character strings, a certain character string is drawn at a high speed by setting the whole character string drawing time short, and a certain character string is slowly set by setting the whole character string drawing time long. You can easily change the speed of drawing, such as drawing, so that it is possible to obtain something that can attract the attention of people who are drawing those characters and impress deeply There is.

According to the invention of claim (9), the character string to be drawn and the entire character string drawing time information, which is information for controlling the time required for drawing the entire character string, are input to the drawing time allocation processing unit. The character drawing time of each character constituting the character string can be automatically calculated and stored in the drawing time information storage unit according to a preset rule. Draws a character string in accordance with these two pieces of information, so that when drawing a character string, it is possible to control the time taken to draw each character constituting the character string. Then, only by changing the whole character string drawing time, the character drawing time of each character at the time of drawing the character string is automatically set, so that the user can start drawing each character from the whole character string drawing time. Time can be controlled. Further, after the drawing of a character constituting the character string is completed, the drawing process may be stopped until a drawing of the next character is started, and a short time may be provided. And just by changing the whole character string drawing time,
Since the character drawing time and inter-character time of each character when the character string is drawn are automatically set, the user needs to calculate the character drawing time and inter-character time of each character from the entire character string drawing time. Is obtained. Therefore, in the case of drawing a plurality of character strings, a certain character string is drawn at a high speed by setting the whole character string drawing time short, and a certain character string is slowly set by setting the whole character string drawing time long. It is easy to change the speed of drawing, such as drawing, and this has the effect of attracting the attention of people who are drawing those characters and impressing them deeply .
