Abstract

PURPOSE: To facilitate the drawing of part of a figure and draw various figures by continuously drawing a selected figure while a drawing device is being commanded to perform continuous drawing based upon a set reference position as a start point of drawing. CONSTITUTION: The driving device 100 consists roughly of a CPU1, an input device 2, a ROM3, a RAM4, and a display device 5. In the ROM3, plural figure data (dot coordinate data) on continuous drawing are previously stored; and keys of the input device 2 are operated to select the registration number corresponding to a figure to be drawn and its reference position. Then, when the continuous drawing is specified with a drawing key, the figure corresponding to the registration number is continuously drawn while the continuous drawing based upon the set reference position as the start point of the drawing is specified by command. Therefore, a part of the figure can easily be drawn and various figures can be drawn only by storing a small number of basic figure data in the ROM3.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawing device suitable for use in, for example, an electronic notebook, an electronic toy, or the like for electronically creating and displaying line drawings and illustration-like images.

[0002]

2. Description of the Related Art In recent years, electronic notebooks and electronic toys having functions of electronically creating and displaying illustration-like portraits and printing out created portrait images on paper have been known. In this kind of product, "eye", "nose",
Various parts image data for drawing each part of the face such as "mouth" and "outline" is registered in the ROM, and the part image data is selected from these parts for each part according to the operation of the operator, for example. Read out the image on the display (for example,
(Color image) is formed. This drawing device is a portrait (face image) created according to the mode specified by the user.
Is stored in the storage means, or the portrait image is printed out on paper.

[0003]

By the way, in the above-mentioned conventional drawing apparatus, a figure having a line as an element (for example, a predetermined line drawing mark, a character represented by a line drawing).
In the case of creating the image data, a plurality of types of parts image data stored in advance in the ROM are selected and read, and these parts image data are combined and drawn.
By selecting the parts image data stored in the OM, only a limited figure can be drawn, and various figures cannot be drawn. In particular, when combining the part image data, it is not possible to use other part images freely created without using the part image data prestored in the ROM for only some of the part images.
For this reason, when trying to draw various figures and storing all the various types of parts image data that should be predicted to be used in ROM in advance, the memory capacity increases and the number of parts image data increases. However, there is a drawback that the selection work becomes troublesome.

Therefore, the present invention has been made in view of the above circumstances, and provides a drawing apparatus capable of easily drawing a part of a figure and drawing various figures with a small amount of image data. It is an object.

[0005]

In order to achieve the above object, a drawing apparatus according to a first aspect of the present invention comprises a data storage unit for storing a plurality of graphic data for continuous drawing, and a predetermined graphic data from the data storage unit. The graphic data selection means to be selected, the reference position setting means for setting the reference position for drawing, the continuous drawing command means for instructing continuous drawing, and the reference position set by the reference position setting means as the drawing start point,
While continuous drawing is instructed by the continuous drawing command means,
Drawing means for continuously drawing a figure corresponding to the figure data selected by the figure data selecting means.

As a preferred mode, for example, as described in claim 2, the graphic data stored in the data storage means has a plurality of dot position information from a drawing reference position, and with respect to this dot position information. It may be composed of drawing order information for specifying the drawing order. For example, as described in claim 3, the drawing means includes a reference position moving means capable of moving the reference position set by the reference position setting means after the drawing is started, and is selected by the graphic data selecting means. The reference point of the graphic corresponding to the graphic data may be moved and drawn. For example, as described in claim 4, the drawing means may include drawing speed changing means for changing the drawing speed. For example, as described in claim 5, a display means capable of displaying the figure drawn by the drawing means may be further provided.

[0007]

In the present invention, a plurality of graphic data for continuous drawing are stored in advance in the data storage means, and the graphic data selecting means selects the desired graphic data to be drawn and sets the reference position thereof. Next, when continuous drawing is input by the continuous drawing command means, the reference position set by the reference position setting means is used as a starting point of drawing and selected by the graphic data selecting means while continuous drawing is instructed by the continuous drawing command means. A graphic corresponding to the created graphic data is continuously drawn by the drawing means. At this time, by changing the period of continuous drawing by the continuous drawing command means, it is possible to draw a figure even with the same figure while changing the size and overall impression. In addition, the drawing figure can be partially deformed by moving the reference point. Therefore, even if a small number of basic graphic data are stored in advance in the data storage means, that is, even if the graphic data to be drawn is not stored in a completed form in advance, the graphic data can be reduced to a small graphic data. It is possible to easily draw a part of the and various shapes.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. A. Configuration of First Embodiment FIG. 1 is a block diagram of a drawing apparatus 100. In FIG. 1, the drawing device 100 is roughly divided into a CPU 1, an input device 2, a ROM 3, a RAM 4, and a display device 5. The CPU 1 performs control necessary for drawing a figure, and constitutes drawing means, drawing speed changing means, and reference position moving means. ROM (data storage means) 3 is C
In addition to various control programs for drawing loaded by the PU1, a plurality of graphic data for continuous drawing are stored. The graphic data is composed of a plurality of dot position information from the drawing reference position and drawing order information for designating the drawing order for the dot position information.

The RAM 4 stores a drawing reference position necessary for drawing a figure, a reference position after the reference position is moved, a drawing speed information, etc., and is used as a work area. The input device 2 includes, for example, a cross key, a decision key, an end key, etc., and is operated by the user. Then, the input device 2 inputs selection of a drawing tool, a drawing figure, a reference position for drawing, a reference position after moving the reference position, change input information for drawing speed, and the like. The input device 2 may include a device such as a mouse, or may be replaced with another input device such as a keyboard or a numeric keypad. The input device 2 and the CPU 1 as a whole include graphic data selection means, reference position setting means, continuous drawing command means,
It constitutes a reference position moving means. Display device (display means) 5
Is for displaying a figure drawn based on the output of the CPU 1, and includes, for example, a CRT display and various circuits for displaying an image (for example, a video display processor: VDP). The drawing output may be externally displayed by the display device 5, but a drawing device may be provided to print the drawing result.

B. Operation of First Embodiment Next, the operation of the embodiment having the above configuration will be described with reference to FIGS.
Will be described with reference to. In the following, first, the processing of the main routine will be described as an operation outline, and then the operations of various routines called in the main routine will be described. Operation of Main Routine First, when the drawing apparatus 100 according to this embodiment is powered on, the CPU 1 reads the corresponding graphic drawing program from the ROM 3 and loads it into itself, and executes the main routine shown in FIG. 2 to execute step S10. Proceed to. In step S10, while various registers / flags provided in the RAM 4 are initialized, the VDP in the display device 5 is instructed to initialize the internal registers, and then an initial menu preset as an initial screen is displayed. Display on screen.

Next, in step S12, the drawing tool cursor is displayed. This is to display the drawing tool cursor at the drawing tool reference position set in the initial setting of step S10. After that, drawing is performed with the position of the drawing tool cursor as a reference. Next, in step S14, key acquisition processing is performed. This captures the input result of the input device 2, and when the cross key, the decision key, the end key, or the like is pressed, the key input is captured. In the processing from step S14 of the key acquisition processing to the drawing processing of step S24 described later, steps S14 to S24 are performed until the end key input of the next step S16 is detected.
The loop of is repeatedly executed.

Next, in step S16, it is determined whether or not the end key has been pressed. If the end key has been pressed, the process returns to end the drawing process. If the end key has not been pressed, the process branches from step S18 to step S22 based on the result of the key acquisition process of step S14. When the key for changing the drawing tool is selected, step S1
The process branches to 8 and the drawing tool change process is performed. Here, the drawing tool will be explained. As shown in FIG. 3A, a typical drawing tool is an "eraser (small)",
There are seven eraser (medium), eraser (large), continuous drawing, pen (small), pen (medium), and pen (large), each of which is "1" to "1". It can be specified by the tool number of "7". Of course, drawing tools other than these may be prepared. For example, “eraser (small)” = tool number “1” erases the diagram with an eraser, and in reality, the color of the diagram is replaced with a transparent color. "Continuous drawing" = tool number "4" is for drawing a line diagram continuously.

On the other hand, when the drawing tool is selected, as shown in FIG.
The registration numbers are assigned according to the selected order as shown in (b). For example, first as a drawing tool, "5" =
When "pen (small)" is selected, the registration number "1" = drawing tool number "5" is registered. When “6” = “pen (middle)” is selected as the second drawing tool, the registration number “2” = drawing tool number “6” is registered. Similarly, the third to seventh drawing tools "7" = "pen (large)" to "3" =
When "Eraser (Large)" is selected, the registration numbers "3" = drawing tool number "7" to registration number "7" = drawing tool number "3" are sequentially registered.

When the process proceeds to the drawing tool change process of step S18 from the result of the key acquisition process of step S14, the process of changing to the drawing tool registered with the next registration number is performed. At this time, when the registration number is the maximum value (for example, the registration number "7"), the minimum registration number is restored. For example, when the drawing tool change process is performed when the registration number is “1”, as shown in FIG. 3B, the drawing tool is changed to the drawing tool “6” registered in the next registration number “2”. It will be. The drawing color changing process of step S20 is performed based on the result of the key acquisition process of step S14. This changes the color of the graphic drawn by the drawing tool selected at that time. Even when the selected drawing tool does not depend on the selected color (for example, when the eraser tool is selected), the drawing color is changed.

When the process moves to the drawing tool moving process in step S22 from the result of the key acquisition process in step S14, the drawing cursor is moved, that is, the drawing reference position is moved. For example, when the key is operated in the up, down, left or right direction by the cross key of the input device 2, the drawing cursor and the drawing reference position move in that direction by a predetermined amount. Next, in step S24, drawing processing is performed. This is to perform drawing corresponding to the drawing key when a drawing key (hereinafter, collectively referred to as a drawing key) is pressed. The details will be described later in a subroutine. When any of the processes of step S18, step S20, or step S24 is executed, the process then returns to step S14 and the above process is repeated. Thereby, the drawing of the figure is performed. Then, the drawing program in which the data of the end key is fetched in step S14 is ended.

Operation of Drawing Process Subroutine FIG. 4 is a flowchart showing a subroutine of the drawing process in step S24 of the main routine. When this subroutine is started, first, the type of drawing tool is determined in step S100. As the types of drawing tools, as shown in FIG. 3A, “pen” and “eraser” are used.
And "Continuous drawing" tools. Step S10
If the drawing tool is a pen tool based on the determination result of 0, the process proceeds to step S102 and drawing is performed according to the size of the pen. Therefore, when the drawing tool is a pen tool, drawing is performed according to the size of the pen. After step S102, the process returns to the main routine.
In step S100, the continuous drawing tool is selected, the process proceeds to step S106, and the state of the drawing key is determined in step S106. When the movement of the drawing tool is input in step S22 of the main routine, the pen drawing reference position is changed and drawing is performed. That is, when the key operation for moving the drawing tool is performed in step S14 in the main routine, the process branches to step S22, and then the process of step S24 is performed. Therefore, when the drawing tool is a pen tool, drawing is performed according to the size of the pen, and when movement of the drawing tool is input at that time, the reference position of pen drawing is changed and drawing is continued.

If the drawing tool is the eraser based on the determination result of step S100, the process proceeds to step S104 to erase the drawing according to the size of the eraser. Then, the process returns to the main routine. Therefore, when the drawing tool is the eraser, the drawing is erased according to the size of the eraser. In addition, step S2 of the main routine
When the movement of the drawing tool is input in 2, the reference position of the eraser is changed and the drawing is erased. That is, when the key operation for moving the drawing tool is performed in the main routine, the process branches to step S22,
Then, the process of step S24 is performed. Therefore, when the drawing tool is the eraser, the drawing is erased according to the size of the eraser, and when the movement of the drawing tool is input at that time, the reference position of the eraser is changed to continue the erasing of the drawing.

If the drawing tool is a continuous drawing tool as a result of the determination in step S100, the process proceeds to step S106 to determine the state of the drawing key. There are the following three modes as the state of the drawing key. NEW_ON: When the drawing key is first pressed NOW_ON: When the drawing key is continuously pressed NEW_OFF: When the drawing key is released (end of the drawing key)

When the drawing key is first pressed (NEW_
ON), the process proceeds to step S108 and the data pointer
Initialize the datanum. The data pointer datanum designates a drawing number of dot coordinate data for drawing a figure continuously. As shown in FIG. 5, the dot coordinate data (that is, the drawing number) for continuously drawing the figures corresponds to the drawing target figure (for example, a spiral figure) and is represented by relative coordinate data from the reference position. To be done. This is set in advance according to the type of figure to be drawn. For example, this example is dot coordinate data corresponding to a spiral figure. By initializing the data pointer datanum, datanum = 0, and the coordinate data (0, 0) of the reference position is designated as shown in FIG. That is, datanum = 0 corresponds to the coordinate data (0, 0) of the reference position. Then, with the coordinate data of the reference position as the drawing start point, the figure is drawn thereafter. In this case, the dodd coordinate data from the reference position (cursor position) is sequentially read in the drawing direction in the right direction and the downward direction.

Then, in step S110, a timer timer
Is initialized. The timer timer controls the time for drawing. Timer = 0 due to initialization of timer timer
After that, the timer timer counts up at a constant rate. Next, in step S112, drawing for ndata is performed based on the data pointer datanum. That is, ndata is drawn from the reference position. This allows
For the designated number of data, the coordinates from the reference position set in step S22 of the main routine are set in step S
A figure is drawn in the drawing color determined in 20. Next, in step S114, the data pointer datanum is set to ndata.
Only increment (datanum = datanum + ndata). As a result, the value of the drawing number is increased by ndata, and ndata will be continuously drawn in the next routine. After step S114, step S100 is performed again.
Return to and repeat the loop.

When continuous drawing is being continued in the next loop, the determination result of step S106 is NOW_ON (the drawing key is continuously pressed). Therefore, at this time, steps S106 to S116 are performed.
Go to and determine whether the timer timer has reached the specified time ntimer. The designated time ntimer is a time designated to draw a plurality of dot coordinate data for continuous drawing. In step S116, the timer timer indicates the specified time ntimer
If not, the process proceeds to step S118 to increment the timer timer (timer = timer + 1). As a result, the value of the timer timer is increased by "1" (corresponding to the set unit time), and continuous drawing is continued according to the dot coordinate data for the unit time of "1" in the next routine. . After step S118, the process returns to step S100 to repeat the loop.

While the loop is being repeated, when the timer timer reaches the designated time ntimer in step S116, the process exits to step S110. This allows the timer ti
The mer is initialized and the process goes to step S110. As a result, drawing is performed from the next drawing number. Next, in step S112, the drawing number is increased, and in step S114
Proceed to. By repeating the above-described loop in this manner, it is possible to draw a part of the previously registered figures or continuously draw all the figures.

To end drawing, step S106
Release the drawing key with. When the drawing key is released (NEW_O
In the case of FF), the subroutine is terminated and the process returns to the main routine. This completes the continuous drawing. When the movement of the drawing tool is input in step S22 of the main routine, the drawing is performed by changing the reference position for continuous drawing. That is, step S1 in the main routine
4, the key operation for moving the drawing tool is performed, the process branches to step S22, and then step S2.
Process 4 is performed. Therefore, when the drawing tool is a continuous drawing tool, continuous drawing is performed while the drawing key is pressed, and when the drawing key is released and the reference position movement is input at that time, the reference position of the continuous drawing figure is changed. Then, continuous drawing is continued.

FIG. 6 is a diagram showing an example of continuous drawing, in which the number of dodd coordinate data for each designated time ntimer is set to "4". First, as shown in FIG. 6A, the number of dodd coordinate data is “4” with the reference position as the start coordinate.
Only drawn. Next, as shown in FIG. 6B, the number of dodd coordinate data = “4” is continuously drawn. After that, similarly, as shown in FIGS. 6C and 6D, the number of dodd coordinate data = “4” in each case.
Only drawn. In this way, ntimer = "4"
When, the drawing transition is performed. FIG. 7 shows an example in which a "spiral pattern" is continuously drawn using the center start point as a reference position. As shown in FIG. 7, while pressing the drawing key,
The coordinate data is increased by the number of dodd coordinate data = “4”, and the dots are continuously drawn. Finally, the “spiral pattern” figure is completed and displayed.

As described above, in the present embodiment, the ROM 3 stores in advance a plurality of graphic data (dot coordinate data) for continuous drawing, and the keys of the input device 2 are operated to correspond to the desired graphic to be drawn. Select the registration number that you want to set and set its reference position. Next, when continuous drawing is designated by the drawing key, the figure corresponding to the registration number is continuously drawn while the continuous drawing is instructed with the set reference position as the starting point of drawing. Therefore, it is only necessary to store a small number of basic graphic data (for example, the dot coordinate data for drawing) in the ROM 3 in advance, that is, the graphic data to be drawn need not be stored in a completed form in advance. Also, it is possible to easily draw a part of the figure and draw various figures with a small amount of figure data.

For example, if the figure is a "swirl pattern",
Large swirl figures or small swirl figures can be drawn freely. Further, the drawing figure can be partially deformed by moving the drawing reference position point.
As a result, various figures can be drawn with less figure data. Therefore, even when various figures are to be drawn, it is not necessary to store various kinds of parts image data in the ROM 3 in advance, which leads to an increase in memory capacity and an increase in the number of parts image data, which makes selection work difficult. It is possible to eliminate the drawbacks such as being troublesome.

C. Second Embodiment FIG. 8 is a diagram showing a second embodiment of the present invention. The present embodiment is an example in which the drawing speed can be changed. In the drawing program of the second embodiment, the processing content of step S112 in the subroutine is different from that of the above-described embodiment, and the rest is the same as that of the first embodiment, and will be omitted. Further, the hardware configuration is different in that the input device 2 is provided with a speed change key. There are two speed change keys, one to increase the speed and one to decrease the speed.
There are types. FIG. 8 shows step S1 in the subroutine
It is a flowchart which shows the detailed routine of the drawing number increase process of 12. When the routine of FIG. 8 is started, first, in step S200, the state of the speed change key is determined. If the speed change key has not been pressed, the process jumps to step S202 and the same process as in step S112 of the first embodiment (the process of drawing ndata based on the data pointer datanum) is executed. After that, the process returns to step S114 similar to the program of the first embodiment. Therefore, the drawing speed does not change at this time.

Of the speed change keys in step S200,
If the speed-up key is pressed, step S20
It branches to 4 and the time interval ntimer is the unit time T of the timer timer.
It is determined whether or not Here, the parameters for changing the drawing speed include a time interval for drawing and the number of dot coordinate data drawn at one time. It is possible to change the drawing speed by changing either one. Step S
If the time interval ntimer is not equal to the unit time T of the timer timer from the determination result of 204, the process proceeds to step S206 to decrease the time interval ntimer (that is, decrease: displayed as timer-sub in step S206). As a result, the time interval ntimer becomes smaller than the unit time T, and the time interval for drawing is shortened. Therefore,
The drawing speed becomes faster. After step S206, the process proceeds to step S202 to execute a process for drawing ndata based on the data pointer datanum, and then returns and repeats the loop.

Continuing the above-mentioned operation, the time interval ntimer indicates the unit time T of the timer timer from the determination result of step S204.
If it is equal to, go to step S208 and set 1
The number of dot coordinate data to be drawn at once (hereinafter referred to as the number of unit drawing dot coordinate data) ndata is increased (that is, increased: displayed in step S206 as ndata + add). As a result, the number of dot coordinate data ndata drawn at one time becomes larger than usual, and the number of drawing dot coordinate data per unit time increases. Therefore, the drawing speed is increased. After step S208, the process proceeds to step S202, where nda is based on the data pointer datanum.
A process for drawing ta is executed, and then the process returns and the loop is repeated.

Of the speed change keys in step S200,
If the key to slow down the speed is pressed, step S21
The process branches to 0 to determine whether the drawing number ndata is equal to the unit drawing number N. The drawing number ndata is the number of dot coordinate data drawn at one time (execution of one subroutine). The unit drawing number N is set to a predetermined value,
For example, N = 1 may be used. If the drawing number ndata is not equal to the unit drawing number N based on the determination result of step S210, the process proceeds to step S212, and the number of dot coordinate data to be drawn at one time (that is, the unit drawing dot coordinate data number) ndat is decreased ( That is, decrease: display as ndata-sub in step S212). As a result, the number ndata of dot coordinate data drawn at one time becomes smaller than usual, and the number of drawing dot coordinate data per unit time decreases. Therefore, the drawing speed becomes slow.

If the result of determination in step S210 shows that the drawing number ndata is equal to the unit drawing number N by continuing the above operation, the process proceeds to step S214 to increase the time interval ntimer (that is, increase: In step S214, it is displayed as timer + add). As a result, the time interval ntimer becomes large and the time interval at which drawing is performed becomes long. Therefore, the drawing speed becomes slow.
After step S214, the process advances to step S202 to execute a process for drawing ndata worth based on the data pointer datanum, and then returns and the loop is repeated.

As described above, in the second embodiment, while the key of the continuous drawing tool is pressed to sequentially draw a figure, if the speed change key is simultaneously pressed while pressing the key,
The drawing speed can be changed by changing the drawing time interval ntimer or the drawing number ndata. Then, after the processing of these speed change keys is finished, a figure is drawn based on the dot coordinate data of the decided number of drawing.
Therefore, when there is a large amount of drawing data, the drawing speed can be increased to shorten the entire drawing time. Further, when it is desired to draw only a part of the figure and to stop the drawing in the middle of the drawing, the drawing speed can be reduced to draw the part of the figure accurately.

D. Modifications In each of the above embodiments, the specified number of dot coordinate data are drawn, but the present invention is not limited to this. For example, the input device is provided with straight line keys for drawing a specified number of straight lines,
While this straight line key is being pressed, a specified number of straight lines may be drawn from the straight line coordinate data prepared in advance (stored in the memory). At this time, a process of sequentially drawing the linear coordinate data from the reference position is performed. In this drawing process, only a fixed number of straight lines are drawn as the linear coordinate data at regular time intervals. With such a configuration, if one key is held down, the designated number of figures can be drawn in a straight line only while the key is held down. When the drawing is performed while moving the reference position, there is an effect that the drawn figure is drawn without interruption in the middle. In the drawing process of the modified example, when drawing a fixed number of straight line coordinate data every fixed time, the drawing time interval or the number of drawn lines is changed by the speed change key of the input device to change the drawing speed. May be. By doing so, when there is a large amount of straight line drawing data, the drawing speed can be increased and the entire drawing time can be shortened. Further, when it is desired to draw only a part of a straight line figure and want to stop the drawing in the middle of the drawing, the drawing speed can be reduced to draw a part of the straight line figure accurately.

[0034]

According to the present invention, a plurality of graphic data for continuous drawing (for example, dot coordinate data) are stored in advance, and the data of the desired graphic to be drawn by operating the keys of the input device. If you select, set the reference position, and specify continuous drawing, the selected figure is drawn continuously while the continuous drawing is instructed with the set reference position as the starting point of drawing. The following effects can be obtained. (1) Only a small number of basic graphic data (for example, Dodd coordinate data for drawing) is stored in the data storage means in advance, that is, all graphic data to be drawn are stored in a completed form in advance. Even if it is not necessary, a part of the figure can be easily drawn and various figures can be drawn simply by storing as a small amount of figure data. (2) For example, in the case of a “swirl pattern” figure, a large swirl figure or a small swirl figure can be freely drawn. (3) The drawing figure can be partially deformed by moving the drawing reference position. As a result, various figures can be drawn with less figure data. (4) Even when trying to draw various figures, it is not necessary to store various kinds of parts image data in the data storage means in advance, which leads to an increase in memory capacity or an increase in the number of parts image data. It is possible to eliminate the drawback that the selection work is complicated.
