It is composed of RT and the like. The key matrix 3 is always time-divisionally scanned by the microcomputer 2, and the state of various function switches is searched.

The figure shape changing device 1 constructed as described above.
The operation of will be described. The figure shape changing device 1 reads arbitrary two figures from the data storage ROM 5 and performs processing on the read figures.
From the figure A in the shape of a face shown in FIG.
An example in which the image is transformed into a graphic B (character) shown in FIG.

[0012]

[Table 1]

The figures A and B are divided into bit images which are constituent elements. That is, for example, in figure A, “face outline”, “left eye”, “right eye”, “nose”, and “mouth” are bit images, and in figure B, “C”, “A”, “S”,
“I”, “O”, and “Trademark mark (R for ○)” are set as bit images, and these bit images are made to correspond as shown in Table 1. Are attached and grouped.

The data storage ROM 5 stores the grouped bit images as a header format as shown in Table 2 (a) and a bit data format as shown in Table 2 (b).

[0015]

[Table 2]

That is, the header format is as shown in Table 2 (a).
As shown in FIG. 7, for the figures A and B, the maximum number of bit images (the number of dots) for each group and x which is the position data of the occurrence / deletion point of the bit image for each group.
The coordinates and the y-coordinate are stored. When the maximum number of points is 0, the position data of the occurrence / disappearance point has no meaning, so that the coordinate data is not normally written.

Table 2 shows the bit data format.
As shown in (b), the position data of each point of the bit image for each group is stored for each of the figures A and B. The x-coordinate of n and point m (the m-th dot) is represented as Xan-m, and the y-coordinate is similarly represented as Yan-m. Therefore, the group No. of FIG. The coordinates of the point of the 0 bit image are (Xa0-0, Ya0-0) to (Xa0
-374, Ya0-374). The position data of the other bit image points is stored in the same manner. The data format has a size corresponding to the figure represented by the point.

The process of changing the graphic from the graphic A thus formatted to the graphic B is performed as shown in FIG. In step S1, the count value of the number-of-times register is initially set to 0. For example, when the change of the image is completed in 64 frames, 64 is set in the register for the number of moving frames.

Subsequently, in steps S2 and S3, data in the header format and bit data format of the graphics A and B are read from the data storage ROM 5 and transferred to the arithmetic RAM 6.

Next, in step S4, common header data is calculated from the header format table
Create it in AM6. This common header data includes the graphic A,
It is necessary to make the number of points for each corresponding group of B one-to-one, and becomes a common header after adjusting the number of point data of figures A and B. As shown in Table 3, the format of the common header compares the maximum number of points for each group of the figures A and B, and writes the larger one into the maximum number of points of the common header. If the maximum number of points on one side is 0 and the maximum number of points on the other side is not 0, the occurrence / deletion position data x, y of the header of the non-zero figure is generated in the header of the common header. Write as x and y. If both points are 0, 0 is written to the maximum number of points in the common header.
In this way, a common header format table is created in the arithmetic RAM 6.

[0021]

[Table 3]

Next, in step S5, a figure A processing subroutine for processing the point data of the figure A is executed based on the common header and the header information of the figure A.

The processing in the figure A processing subroutine is as follows.
This is shown in FIG. In step S21, group N
o. Set 0 to the group counter that counts
In step S22, the group No. corresponding to the count value of the group counter from the common header and the header of FIG.
Is read from the data recording ROM 5.

Subsequently, in step S23, the maximum number of points in the header of the graphic A is compared with the maximum number of points in the common header. If the maximum number of points in the common header is larger, the process proceeds to step S24, where If the maximum number of points is smaller or the same, the process proceeds to step S27.

In step S24, it is determined whether the maximum number of points in the header of the graphic A is 0. If it is 0, the process proceeds to step S25, and if not, the process proceeds to step S26.

In step S25, since the maximum number of points in the header of the figure A is 0, that is, there is no corresponding group, the group No. designated by the group counter is not displayed. Is generated as the point data of the graphic A by the maximum number of points of the common header, and the process proceeds to step S27. That is, a corresponding number of data is newly generated. On the other hand, in step S26, since the maximum number of points in the header of the graphic A is not 0, the group No. designated by the group counter is set. Up to the maximum number of points of the common header of the group No. Extends the number of point data in the header of the corresponding figure A, and proceeds to step S27.

Enlarging the data means, for example, that the group No. of the header of the graphic A shown in Table 2 (a). The maximum number of points for group 1 is 34. As shown in Table 3, the maximum number of points of the common header corresponding to 1 is 307. Therefore, the difference 273
(= 307-34) is shown in FIG.
As shown in (a) and (b), the point is adjusted (data is added) without changing the image so that the points are overlapped at the same position.

[0028]

[Table 4]

Then, in step S27, 1 is added to the group counter for the next processing, and
Proceed to 28. In step S28, for example, when the maximum number of groups is set to 16, the value of the group counter becomes 16
It is determined whether or not the processing has reached 16. If the processing has not reached 16, the procedure returns to step S22 to repeat the processing.

Returning to FIG. 3, in step S6, the processing of the figure B processing subroutine is executed. This graphic B processing subroutine differs from the graphic A processing subroutine of step S5 only in that the data of the graphic A is changed to the data of the graphic B.
Since the contents of the processing are the same, the description is omitted.

Subsequently, in step S7, step S5
And by processing in step S6, the figure A
And the point data of FIG. B have a one-to-one correspondence, the difference between the coordinates for each corresponding point data, ie, B
x-Ax and By-Ay are calculated, and this difference is divided by the number of moving frames (the number of frames when changing from FIG. A to FIG. B, which is 64 in the embodiment of FIG. 5 described later) to obtain a difference point. Create data (Δx, Δy).

The timer interrupt subroutine shown in FIG. 5 is a process that is performed at regular intervals and actually changes the shape of a figure. As shown in FIG. 5, in this timer interrupt routine, it is determined whether or not the time counter is 0 in step S41. If it is not 0, the process proceeds to step S42, and if it is 0, the process proceeds to step S44. The time counter is a counter that changes according to the number of moving frames.

In step S42, the time counter is set to 6
It is determined whether the number is 4, and if the number is 64, the number of moving frames becomes 64, and the transformation to the graphic B is completed.
If the time counter is not 64, step S4
Proceed to 3.

In step S43, the difference point data (Δx,
Δy) (the data obtained in step S7 in FIG. 3), and the process proceeds to step S44. From this time, the point data of the figure A becomes the point data during the change of the figure shape.

In step S44, the microcomputer 2 executes a subroutine for transferring the point data of the graphic A to the driving device 8, and displays an image on the display element 7. And
In step S45, 1 is added to the time counter, and the process ends. By executing such a timer interrupt subroutine process at regular time intervals, the graphic shape can be sequentially changed.

FIG. 6 shows an operation example of the present embodiment, in which changes from 0 frames to 64 frames are displayed every four frames. As shown in Table 1 above, the group N of FIG.
o. For the trademark mark of No. 5, the group No. corresponding to FIG. Since the point data does not exist in FIG. 6, in the state where the graphic A of the fourth frame in FIG. 5 is used as the generation / disappearance point (in this case, the generation point). Then, the generation point gradually moves to the position of the trademark mark of the graphic B and changes each time the frame advances. In this example, the figure A of the person's face changes to a character figure of “CASIO” via a figure in the middle of 62 frames.

FIG. 7 shows a change in the figure shape of another figure stored in the data storage ROM 5 (change from the character figure "RUN" to the figure "running person figure"). The portion surrounded by the dotted line of the 0th frame (the portion indicated by reference numeral b in the figure) is the group number of the other figure. Because there is no point data at the point, the pieces come together each time the frame advances to the occurrence / disappearance point. As shown at the center point of 60 frames (the point indicated by the symbol c in the figure), one point before the disappearance comes to a state where it almost gathers at one point, then disappears and changes to a desired figure.

FIGS. 8 and 9 show an example of a change in the figure shape of the figure stored in the data storage ROM 5 when the present embodiment is applied to educational equipment. Is a change from a "drawing figure" to a character figure "WRITE". In FIG. 9, the "figure of house"
From the character figure "HOUSE" to the character figure "HOUSE".

The interrupt subroutine processing is executed at fixed time intervals for each frame. However, the present invention is not limited to this. As shown in Table 5, the interrupt subroutine processing is executed with the time of change changed for each frame. You may do it.

[0040]

[Table 5]

That is, in the change of the figure shape, for example, the original figure remains unchanged until about the first 12 frames, and approaches the final figure in about 12 frames before the end frame. Change. Focusing on this point, as shown in FIG. 10, the figure may be changed slowly at first, the change speed is increased in the middle of the change, and the change speed is slowed down again in the second half. By changing the shape in this way, there is an advantage that the figure shape looks more natural.

As described above, according to the figure shape changing apparatus of the first embodiment, two figures are selected from the point data of an arbitrary plurality of figures stored in the data storage ROM 5, and one of the figure data is selected in real time. From the other figure to the other figure.

Next, a second embodiment will be described. FIG.
1 to 13 relate to the second embodiment of the present invention, and FIG. FIG. 12 is a flowchart illustrating a flow of a process of changing a graphic shape, and FIG. 13 is a flowchart illustrating a process flow of a graphic A (B) processing subroutine in FIG. It is a flowchart. In the second embodiment, the configuration of the graphic shape changing device is the same as that of the first embodiment, but the method of processing the graphic change by the microcomputer is different.

The graphic change processing of the second embodiment will be described using an example of change from graphic A to graphic B shown in FIG. 1 as in the first embodiment. In the figures A and B, the bit images as the respective constituent elements correspond to each other according to the above-described Table 1 similarly to the first embodiment. Are attached and grouped.

In the data storage ROM 5, the grouped bit images are stored as a header format as shown in Table 6 (a) and a bit data format as shown in Table 6 (b).

[0046]

[Table 6]

That is, the header format is as shown in Table 6 (a).
As shown in FIG.
The maximum number of bits (the number of dots) of the bit image for each group and the x-coordinate and the y-coordinate which are the position data of the occurrence / disappearance point of the bit image header are stored. When the maximum number of points is 0, the position data of the occurrence / deletion point has no meaning, and no data is written.

As shown in FIG. 11, when there are a plurality of figures whose figure shape is to be changed,
o. Indicates the relationship between the figures associated with each other. For example, FIG. Are associated with each other, and FIG.
Group no. Indicates that they are associated with each other. That is, the figure A is assigned to the corresponding group No. by the figure correspondence number 1. Changes to a graphic B, and the graphic corresponding number 4 changes the graphic B to a graphic E in the same manner. Therefore, the change from the graphic A to the graphic E can be associated with the graphic correspondence number from 1 to 4. The same applies to other graphics. Table 7 shows the relationship between graphics and graphic correspondence numbers.

[0049]

[Table 7]

Table 6 shows the bit data format.
As shown in (b), the position data of each point of the bit image for each group is stored for each of the figures A and B. n, the x coordinate of the point m is Xan-m, and similarly, the y coordinate is
Yan-m. Therefore, the group N of the figure A
o. The coordinates of the point of the 0 bit image are (Xa0
−0, Ya0-0) to (Xa0-374, Ya0-37)
4). The position data of the other bit image points is stored in the same manner.

As described in Table 7, a plurality of graphic correspondence numbers are assigned to one graphic.
Not limited to the header format shown in Table 6 (a),
As shown in Table 8, a plurality of figure correspondence numbers may be assigned to create a header format, and the figure after the change of the figure shape may be set by selecting the figure correspondence number.

[0052]

[Table 8]

As shown in FIG. 12, the processing for changing the figure from the figure A thus formatted to the figure B is almost the same as that in the first embodiment, but the processing in steps S4 to S6 in FIG. Is different from the first embodiment only, and only different processes will be described. That is,
12, steps S61 to S63 are the same as steps S1 to S3 in FIG. 3, and step S67 is the same as step S67 in FIG.
Same as 7. Therefore, steps S64 to S66 different from the first embodiment will be described, and description of other processes will be omitted.

In step S64, change header data is created in the arithmetic RAM 6 in accordance with the figure corresponding numbers from the header format tables of the figures A and B. If figures A and B have the same figure corresponding number, the same group N
o. Therefore, the change header of the figures A and B is
As shown in Table 9 (a), they become common (that is, Table 3
This is the same change header as the embodiment shown in FIG. on the other hand,
If figures A and B have different figure correspondence numbers, see Table 9 (b).
As shown in FIG. Group Nos. In ascending order of the occurrence / disappearance point position. Correspond. For this reason, the change headers for the figures A and B are different. Rather than associating as shown in Table 9 (a),
As shown in Table 9 (b), a more natural shape change can be realized by associating groups at closer positions with each other.

[0055]

[Table 9]

The header data for change is necessary to make the number of points in each of the corresponding groups of the figures A and B one-to-one correspond to each other. It becomes a header. In the format of the change header, the maximum number of points for each group of the graphics A and B is compared, and the larger one is written in the maximum number of points of the change header. If the maximum number of points on one side is 0 and the maximum number of points on the other side is not 0, the occurrence / deletion position data x, y of the header of the non-zero figure is changed to the generation / deletion position data of the header of the change header. Write to x and y.
If both points are 0, 0 is written as the maximum number of points in the change header. In this way, a change header format table is created in the arithmetic RAM 6.

Next, in step S65, a figure A processing subroutine for processing the point data of the figure A is executed based on the change header and the header information of the figure A. The processing in the figure A processing subroutine is as shown in FIG.
In step S81, the group No. Is set to a group counter that counts the group No. corresponding to the group counter from the change header and the header of the graphic A in step S82. The maximum number of points for data recording R
Read from OM5.

Subsequently, in step S83, the maximum number of points in the header of FIG. A is compared with the maximum number of points in the change header. If the maximum number of points in the change header is larger, the flow advances to step S84 to change the number of points. If the maximum number of points in the header for use is smaller or the same, step S8
Go to 7.

In step S84, it is determined whether the maximum number of points in the header of the graphic A is 0. If it is 0, the process proceeds to step S85, and if it is not 0, the process proceeds to step S86.

In step S85, the maximum number of points in the header of the graphic A is zero. That is, since there is no corresponding group, the group No. designated by the group counter. Is generated as the point data of the graphic A by the maximum number of points of the change header, and the process proceeds to step S87. On the other hand, in step S86, since the maximum number of points in the header of the graphic A is not 0, the group No. designated by the group counter is set. Up to the maximum number of points in the change header of the group No. Is extended, and the process proceeds to step S87.

The process of expanding data is the same as in the first embodiment.

Then, in step S87, 1 is added to the group counter for the next processing, and step S87 is performed.
Go to 88. In step S88, for example, when the maximum number of groups is set to 16, the value of the group counter becomes 16
It is determined whether or not the processing has reached 16. If the processing has not reached 16, the processing returns to step S82, and the processing is repeated. .

Returning to FIG. 12, in step S66, the figure B
The processing of the processing subroutine is executed. The graphic B processing subroutine is the same as the graphic A processing subroutine in step S65 except that the data of the graphic A is changed to the data of the graphic B, and the processing is the same.
The other processing flow is the same as in the first embodiment, and a description thereof will be omitted.

Next, a third embodiment will be described. FIG.
4 to 16 relate to the third embodiment, and FIG. 14 is an explanatory view for explaining a figure of a deformed figure by the figure shape changing device.
5 is a flowchart for explaining the flow of the processing of the graphic A (B) processing subroutine with respect to FIG. 14, and FIG. 16 is an explanatory diagram for explaining the state of change from graphic A to graphic B in FIG. In the third embodiment, the configuration of the figure shape changing device is the first.
This is the same as the embodiment, but the method of processing the figure change by the microcomputer is different.

The graphic change processing of the third embodiment will be described using an example of a change from graphic A to graphic B shown in FIG.

In the figures A and B, the bit images as the respective constituent elements are made to correspond to each other as shown in Table 10, and the group No. is assigned to the corresponding bit images. Are attached and grouped.

[0067]

[Table 10]

The data storage ROM 5 stores the grouped bit images of the graphics A and B as a header format as shown in Table 11 (a) and a bit data format as shown in Table 11 (b). ing.

[0069]

[Table 11]

The data storage ROM 5 has a table 12 shown in FIG.
As shown in the figure, the generation / deletion instruction data of the graphics A and B are stored, and the instruction flag of the generation / deletion instruction data is set to o.
n, the group number of the graphic to be changed (graphic B as viewed from graphic A, graphic A as viewed from graphic B). Group No. corresponding to If there is no, the occurrence / deletion position is ignored and the group No. Assign.

[0071]

[Table 12]

The processing of the graphic change from the graphic A to the graphic B in FIG. 14 thus formatted is almost the same as that of the first embodiment.
Since the processing in steps S6 to S6 is different from that of the first embodiment, only different processing will be described.

That is, step S in the third embodiment.
In the processing of No. 4, as shown in Table 13, the format of the common header compares the maximum number of points for each group of the figures A and B, and writes the larger one into the maximum number of points of the common header. If the maximum number of points is 0,
If the other flag has a non-zero maximum point number and the instruction flag of the generation / deletion instruction data of the non-zero maximum point number is off, the generation / deletion position data x of the header of the figure having a non-zero maximum point number is not 0. , Y to the header occurrence / deletion position data x, y of the common header.

[0074]

[Table 13]

If the instruction flag of the generation / deletion instruction data of the non-zero maximum point number is on, the data of the maximum point number of zero is generated. No. Replace with the maximum number of points specified by and compare again.

If both points are 0, 0 is written to the maximum number of points in the common header. Thus, the common header format table is stored in the arithmetic RAM 6.
Is created.

The graphic A processing subroutine, which is the processing of step S5 in the third embodiment, is as shown in FIG. That is, in step S101, the group No.
Is set to 0 in the group counter that counts the group number corresponding to the group counter in step S102 from the common header and the header of FIG. Is read from the data recording ROM 5.

Subsequently, in step S103, the maximum number of points in the header of FIG. A is compared with the maximum number of points in the common header. If the maximum number of points in the common header is larger, the process proceeds to step S104, and the process proceeds to step S104. If the maximum number of points is smaller or the same, step S10
Go to 9.

In step S104, it is determined whether the maximum number of points in the header of FIG. A is 0. If it is 0, the process proceeds to step S105.
Proceed to.

In step S105, it is determined whether or not the instruction flag of the occurrence / destruction instruction data is on. If it is on, the process proceeds to step S106, and if it is off, the process proceeds to step S107.

In step S106, the group No. of the generation / deletion instruction data of FIG. As shown in Table 14, all the point data specified in (Table 12) are assigned to the group No. of the graphic A specified by the group counter. As a result of this processing, the maximum number of points in FIG. Therefore, the maximum number of points read from the data storage ROM 5 is rewritten to the current maximum number of points, the process returns to step S103, and the process is repeated.

[0082]

[Table 14]

In step S107, the group No. designated by the group counter is set. Is generated as the point data of the figure A by the maximum number of points of the common header, and the step S10 is performed.
Go to 9. On the other hand, in step S108, since the maximum number of points in the header of the graphic A is not 0, the group No. designated by the group counter. Up to the maximum number of points of the common header of the group No. Is extended as shown in Table 15, and the process proceeds to step S109.

[0084]

[Table 15]

Then, in step S109, 1 is added to the group counter for the next processing, and the flow advances to step S110. In step S110, for example, when the maximum number of groups is set to 16, it is determined whether or not the value of the group counter has reached 16. If not, the process returns to step S102, and the process is repeated until the number becomes 16. For example, the process ends, and the process proceeds to the graphic B processing subroutine (step S6 in FIG. 3) of the third embodiment.

This graphic B processing subroutine is the same as the graphic A processing subroutine (FIG. 15) as in the first embodiment.
However, only the data of FIG. A is changed to the data of FIG. B, and the content of the processing is the same. Other processing flows are the same as in the first embodiment.

With the above processing, in the third embodiment, the instruction flag of the generation / deletion instruction data of FIG.
When the change from FIG. A to FIG. B at ff is displayed every 16 frames, the result is as shown in FIG. 16B. The upper right circle and lower center circle of FIG. Since they do not exist in B, they converge at the occurrence / disappearance points set near the center of each circle and disappear. The circle at the upper left of FIG. A is the corresponding group of FIG.
Changes towards the center circle of.

On the other hand, when the instruction flag of the generation / deletion instruction data of FIG. B is on, as shown in FIG.
The circle at the upper right of the figure A and the circle at the lower center of the figure A have no corresponding group in the figure B. 0
Is assigned, and all circles gather toward the center circle of the figure B.

As described above, in the third embodiment, the processing as in the first embodiment can be selected, or the group No. can be selected according to the occurrence / destruction instruction data. By assigning the point data of FIG. 14, the shape of the figure can be changed. In addition to the effects of the first embodiment, the figure shown in FIG. A balanced figure change can be performed.

In the above embodiment, the figure A or B
