M, which functions as a non-volatile memory by, for example, backup by a battery. The interior is divided into several parts, each used for a specific purpose. Each area in the RAM 16 will be briefly described below.

The work area 16a is used to operate the above-described program and temporarily store data when copying a completed image. The image storage area 16b is an area for storing a created image or an image as a result of copying. The random number storage area 16c is an area for storing the generated random numbers.

The coordinate table 16d is an area for storing XY coordinates on the screen defined by random numbers. The angle table 16e is an area for storing an angle indicating the inclination of each copy image specified by a random number. The color tone table 16f is an area for storing numerical values obtained by converting the color tone of each copy image specified by a random number into data. The cursor pointer 16g is an area for storing the position of the cursor displayed on the display screen on the screen as a numerical value.

FIG. 2 is a diagram for explaining the relationship between the coordinate table, the angle table, the color tone table, and the cursor pointer. The coordinate table 16d is composed of (Xn, Yn) coordinate data representing a coordinate point, as shown in (1) of FIG. The coordinate table 16d generates a coordinate sequence indicating a position within a predetermined area (in this example, an LCD display area) based on the random numbers stored in the random number storage area 16c, and stores this as shown in (1) of FIG. It was done.

Referring again to FIG. 1, reference numeral 17 denotes a floppy disk driver (FD) as an external storage device, which stores an image, a coordinate table, an angle table, a color tone table, and the like. In the present embodiment, the FD 17 is used as the external storage device.
However, any storage medium such as a hard disk or a magneto-optical disk may be used. Reference numeral 18 denotes a printer (PRT) for printing the created image.

The operation of the information processing apparatus of the present embodiment having the above configuration will be described below. FIG. 4 is a flowchart illustrating a procedure of a process according to the present embodiment. FIG. 5 is a diagram illustrating an example of creating an image by the information processing apparatus according to the present embodiment. In the following description, FIG.
An example in which a plurality of apple images shown in (1) are arranged to design an image will be described.

Firstly, create an image 52 of the apple as shown in FIG. 5 (1), the image data is image storage area 16
Assume that it is stored in b. Since the process for generating the apple image can be easily realized with the conventional technology, the details of the process up to this point are omitted. When an image is completed as shown in (1) of FIG. 5 and an image is designed by arranging a plurality of images, the process shown in the flowchart of FIG. 4 is started.

In the flowchart of FIG. 4, before copying the created apple image, a random number is first generated. The generated random numbers are stored in a random number storage area 16c of the RAM 16.
(Step S1). Then, based on the random numbers stored in the random number storage area 16c, a predetermined number of XY coordinate positions within a range that fits on the screen are calculated, and the coordinate table 1 is calculated.
6d. In addition, a random angle data string is generated in the range of 0 to 359 degrees based on the random numbers, and this is stored in the angle table. Furthermore, a tone data structure is generated based on the random numbers,
A random tone data sequence is generated and stored in the tone table 16f (step S2). Although the color tone data is shown in FIG. 3 , yellow (Y), magenta (M), and cyan (C) are stored in each of 4 bits.

[0027] Thereafter, the cursor 5 as shown in FIG. 5 (1)
1 is displayed at the leftmost position on the screen, and the cursor pointer 16g is displayed.
Is set to 0 (step S3). In this state, KB1
Waiting for the operation of the key on 2 (step S4), and when any key is input, branching is performed by that key (step S5).

When the cursor right key is operated, a process of multiplying the image 52 (copying it to a random position in a random direction) is performed. First, the cursor pointer is incremented by one. Here, since the range of the number of movements of the cursor is limited, a limit check is also performed so as not to exceed a prescribed maximum value. Thereafter, a cursor is displayed on the LCD 13 at a position corresponding to the value of the cursor pointer 16f (step S6). As a result, the cursor 51 moves rightward and is displayed.

Next, the image storage area 16b of the RAM 16
Is copied to the work area 16a. The apple image data is stored in the storage area 16b including information such as the size. Then, a rotation process and a color tone change process are performed on the copied image, and the processed image is displayed. Here, the rotation angle in the rotation processing is determined by the angle data indicated by the cursor pointer 16g in the angle table 16e. Also, the content of the color change in the color change process
It is determined by the color tone data indicated by the cursor pointer 16g in the color tone table 16f. Further, the display position of the processed image is determined by the coordinate data indicated by the cursor pointer 16g in the coordinate table 16d. That is, the image data subjected to the rotation processing and the color tone change processing is
It is pasted at a position corresponding to the display position indicated by the coordinate data in the image storage area 16b. Then, the contents of the image storage area 16b are transferred to the VRAM 14 and displayed on the LCD 13 (step S7).

The above steps S6 and S7 are repeated by the number corresponding to the amount of movement of the cursor pointer (step S6).
8). For example, assume that the cursor is moved rightward and the cursor pointer changes from 0 to 3. In this case, the coordinate table 16d, the angle table 16e, the color tone table 16
The three pieces of data from the top of each of f are used, and three copy images are generated and displayed (see (2) in FIG. 5). In (2) of FIG. 5, the change in color tone is not shown.

That is, in the first loop of steps S6 to S8, the cursor pointer becomes 1, the coordinate data (X1, Y1), the angle data θ1, and the color tone data C1 are read from each table, and the image data is read in accordance with these data. Rotation, color change, and paste are performed. Similarly, the processing is executed using (X2, Y2), θ2, C2 in the second loop, and (X3, Y3), θ3, C3 in the third loop. As a result, three images are newly stored in the image storage area. The result is transferred to the VRAM and displayed on the LCD. Thus, when three images are copied, the original image and a total of four images are displayed. The state is shown in FIG. When the cursor rightward movement is further repeated, the image repeats multiplication and becomes as shown in FIG. 5 (3). Note that, in (3) of FIG. 5, a change in color tone is not shown.

On the other hand, when the cursor is moved to the left, the cursor pointer 16g is decremented by one. At this time, a limit check is performed so that the content of the cursor pointer 16g does not become 0 or less. Thereafter, a cursor is displayed on the LCD 13 at a position corresponding to the value of the cursor pointer 16f (step S9). As a result, the cursor 51 moves to the left and is displayed.

Then, the coordinate data in the coordinate table 16d indicated by the value of the cursor pointer 16f before the update in step S9 is acquired, and the copy image pasted at the position indicated by the coordinate data is deleted (step S9). S10). These processes of steps S9 and S10 are repeated by the number corresponding to the amount of movement of the cursor (step S1).
1). Here, since the pasting position of the copy image is determined by a random number, a plurality of apples may overlap each other. In the above-described erasing operation, when an apple having such an overlapped portion is erased, it is necessary to restore a portion hidden by the erased image. In the present embodiment, in order to cope with such a situation, step S
At 10, the data up to the pointer indicated by the cursor pointer 16g is newly rewritten. According to the process of FIG. 4, the cursor pointer is decremented by one, and the drawing of the image is repeated in step S10. However, the total amount of cursor left movement by the user's operation is detected, and the cursor pointer is updated. By performing the drawing, the number of times of redrawing the image can be reduced, and the processing speed is improved.

As described above, the copy image of the apple 52 is
Just by moving the cursor 51 right or left, it is displayed or disappears at a random position while randomly changing the angle or color. Images are always stored in the image storage area 16b
Is stored in the coordinate table 16.
d, F together with the angle table 16e and the color tone table 16f
With D17, it can be stored on a floppy disk. Therefore, the same processing can be performed again by reading these data from the FD 17.

In order to print the image after the design, the contents of the image storage area 16b of the RAM 16 are stored in the PRT.
18 is output.

As described above, according to this embodiment, an image can be easily copied and pasted at random positions at random rotation angles and color tones.
In addition, the number of pasted copy images can be increased or decreased by moving the cursor 51 left or right, so that operability is significantly improved.

[0037]

Further, in the above-described embodiment, as the processing method of the copy image, three types of the random pasting position, the random rotation angle, and the random color tone are used, but the present invention is not limited to this. For example, only a random pasting position is executed, a copy image rotated at a random rotation angle is pasted at a random pasting position, or a random tone change is applied to a random pasting position and copied. An image may be pasted. Further, it may be possible to select which of these methods to use.
