Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image creation system for creating pictures on the screen of a television receiver, for example.

[Summary of the invention]

The present invention relates to an image creation system for creating a picture on the screen of a television receiver, for example, and the present invention relates to an image creation system that creates a picture on the screen of a television receiver. It has a color designation button designed to make it possible to distinguish between colors, and a cursor moving means for moving the cursor on the screen. Change the color of the selected character pattern to the desired color using the color specification button, move this cursor to the desired position on the screen using the cursor moving means, and move the character pattern corresponding to this cursor to the desired position on the screen. By setting the characters to be fixed, the selection of a desired character and the color of the selected character are made much easier and easier to understand, and pictures can be created better on the screen.

[Conventional technology]

2. Description of the Related Art Conventionally, image creation systems for creating pictures on the screen of a television receiver, for example, have been proposed.

This image creation system consists of a main body having a well-known tablet and a set of keys. This imaging system then displays several equally sized (e.g. 16
When a 16-dot (16-dot) character is displayed and the user selects a desired character from among the characters displayed on the monitor screen using a select key, the cursor becomes the selected character. In addition, if the desired character is not among the characters displayed on the monitor screen, the user can display some other characters on the monitor screen and add new characters to the screen. A desired character can be selected from several other displayed characters using a select key or the like. Further, the color of the selected character is selected using a color selection key or the like, and the color of the character is thereby changed on the screen.

Then, the user moves the cursor to a desired position on the monitor screen by specifying a desired position on the monitor screen with a special pen on the tablet corresponding to the monitor screen, and further, By pressing the position determination key, the character that becomes the cursor at that position is determined.

In this way, conventional image creation systems sequentially display several groups of characters on a monitor screen, select a desired character from the group of displayed characters, use it as a cursor, and move the cursor. After specifying a position on the tablet, a picture was created on the monitor screen by fixing the character that served as the cursor at that position.

[Problems to be Solved by the Invention] By the way, in the above-mentioned image creation system, the user selects a desired character from several characters displayed on the monitor screen using a select key, or selects another character. Several new characters are displayed on the monitor screen, and the desired character is selected from the displayed characters using a select key, so it is possible to select the desired character from among the displayed characters. Not only is it impossible to select a character while viewing all of them, but the character selection process is also inconvenient.

In addition, the color of the selected character is determined after selecting the color using a color selection key, etc., and checking the selected color on the monitor screen, so you can use a list of pre-prepared color shades. However, this not only makes it impossible to select a color, but also complicates the process of selecting a color for a character. Further, as described above, since the process of selecting a character and selecting the color of the selected character is complicated, there is an inconvenience that the process of creating a picture on the screen is complicated.

In view of these points, the present invention makes it easy and easy to select a desired character and the color of the selected character, and improves the ability to create pictures on the screen. This is an attempt to propose a creation system.

[Means to solve the problem]

For example, as shown in FIGS. 1 to 5, the present invention provides character selection buttons (22), (23) that are arranged so that character patterns can be distinguished, and the color of the character patterns on the screen of the display device (8). It has a color designation button (21) designed so that the color can be distinguished, and a cursor moving means (10) to move the cursor on the screen, and a character selection button (22) to change the shape of the cursor on the screen. ), (
23) to set the desired character pattern, change the color of this selected character pattern to the desired color using the color designation button (21), and move this cursor to the cursor moving means (10).
) to a desired position on the screen, and the character pattern serving as this cursor is fixed at the desired position on the screen.

[Operation] According to the present invention described above, the shape of the cursor on the screen of the display device (8) is changed to the character selection button (22), (23).
Set the desired character pattern to the desired character pattern, set the color of the selected character pattern to the desired color using the color designation button (21), and move the cursor to the desired position on the screen using the cursor moving means (10). Since the character pattern, which is the cursor, is fixed at the desired position on the screen, it is easy and easy to select the desired character and the color of the selected character. The picture above can be created well.

In step (1100), it is determined whether any key (see FIG. 2 or 3) has been pressed, and rYEs
If it is J, the process moves to step (1200), and if it is rNOJ, the process moves to step (1100) again.

In step (1200), the cursor is initialized. As shown in FIG. 4, the initial setting of this cursor is, for example, to indicate a predetermined abstract figure (for example, a circle) in the storage area of RAM (4) using a program stored in advance in ROM (3). Figure number, position χ and Y (
This is accomplished by storing the coordinates of the horizontal and vertical axes on the monitor surface, and color data, respectively. Then, based on the data in this storage area, a predetermined figure is displayed with predetermined color data on the RAM (6) corresponding to the screen of the monitor [8] via the bus (2). It is stored in a predetermined location. Then, the video processor (5) reads the data from this RAM (6), and this read image data is sent to the encoder (for example, NTSC).

Then, the process moves to step (1300).

In step (1300), joystick (10)
It is determined whether or not has been moved, and if rYESJ, the process moves to step (1400), and if rNOJ, the process moves to step (1500,).

In step (1400), the RAM
The position X and Y data in the storage area (4) is input from the joystick (10) in response to the digital position information signal supplied via the A/D conversion circuit (12), gate circuit (14) and bus (2). Furthermore, based on these data, the figure stored in ROM (3) according to the figure number is changed at any time in RAM (6) at position X and with color data according to the color number. Store it in the position (address) corresponding to Y.

Then, the video processor (5) uses this RAM (6
), and this read image data is supplied to the monitor (8) via the encoder (7), so that the abstract figure that is used as a cursor can be drawn, for example, as shown in FIG. 6B. The image is projected at the position shown. Then, the process returns to step (1300).

In step (1500), it is determined whether the background color sum (slide volume 1 (11) has been moved or not, rYE
If it is sJ, move to step (1600) and rNOJ
If so, the process moves to step (1700).

In step (1600), the portions other than the graphics on the screen of the monitor (8) are colored with the specified background color, that is, R
The color data of the specified background color is stored in the address area corresponding to the background of A M (6). Then, the process returns to step (1300).

In step (1700), it is determined whether any key has been pressed, and if rYEsJ, step (1800) is performed.
If rNo, go to step (1300) again.

In step (2300), the color of the cursor is changed.

That is, as shown in FIG. 4, the color data of the color in the storage area of RAM (4) is changed to the color data corresponding to the color designated by the color designation key (21). This allows R.A.
M(6) stores the graphics in the storage area described above using the color data stored in RAM(4). Then, the video processor (5) uses RAM (6
), and the read image data is sent to the monitor (8) via the encoder (7).
, and a figure placed as a cursor on the screen of the monitor (8) is displayed in the color specified by the color specification key (21). For example, as shown in Figure 6C, the color designation key (2
When you press 1g), the abstract figure turns green. Then, the process returns to step (1300).

In step (2400), it is determined whether the abstract figure key (22) has been pressed, and if rYEs, step (
2500), and if NO, step (26

In step (2500), the shape of the cursor is changed.

That is, as shown in FIG. 4, the figure number data of the figure number in the storage area of RAM (4) is stored in the abstract figure key (22).
Change the figure number data to correspond to the figure specified in . As a result, RAM (6) has the above-mentioned RA
Graphic data corresponding to the graphic number data stored in RAM (4) is read out from R'OM (3), and this read graphic data is stored in RAM (6) based on each data in the storage area described above. ) is memorized. Then, the video processor (5) reads the image data stored in the RAM (6), and the read image data is
The figure is supplied to the monitor (8) via the encoder (7), and the figure set as a cursor on the screen of the monitor (8) is displayed as the figure specified by the abstract figure key (22). For example, as shown in the sixth diagram, when the abstract figure key (22) with a square symbol is pressed, the cursor, which was previously in the shape of a circle, becomes square. Then, the process returns to step (1300).

In step (2600), it is determined whether or not the concrete figure key (23) has been pressed, and if r Y, E S J, the process moves to step (2500), and if it is rNO, the process moves to step (2700). do.

In step (2500), the shape of the cursor is changed.

That is, as shown in FIG. 4, the figure number data of the figure number in the storage area of RAM (4) is input to the concrete figure key (23).
Change the figure number data to correspond to the figure specified in . As a result, RAM (6) has the above-mentioned RA
Graphic data corresponding to the graphic number data stored in M (4) is read out from ROM (3), and this read graphic data is stored in RAM (6) based on each data in the above-mentioned storage area. Forced to remember. Then, the video processor (5) reads the image data stored in the RAM (6), and this read image data is supplied to the monitor (8) via the encoder (7). The figure placed as a cursor on the screen is displayed as the figure specified by the concrete figure key (23).

Then, the process returns to step (1300).

After this, for example, the process returns to step (1300), moves the abstract figure to the position shown in FIG. 6E using the joystick (10), and presses the execution key (33) in step (2000). As shown in Figure 6F,
The position, two colors, and shape of the figure are determined, and the cursor remains at the same figure.

In step (2700), it is determined whether the erase key (35) has been pressed, and if it is rYEsJ, step (28
00), and if r, NOJ, step (290
0). Note that this erase key (35) erases a figure on the screen using, for example, a pointer P for specifying a hand shape range, which will be described later, and also erases all figures of this figure from the storage area shown in Fig. 4. It erases information.

In step (2800), the shape of the cursor is changed to
The pointer P is changed to a hand-shaped range designation pointer P as shown in FIG. Then, the process returns to step (1300).

In step (2900), it is determined whether the previous/rearward designation key (34r) or (34f) has been pressed, and rYEs
If it is "J", the process moves to step (2800), and the shape of the cursor is changed to a range specifying pointer P; if "NO", the process moves to step (30QO).

In step (3000), it is determined whether the scroll key (37) has been pressed, and if rYEsJ, the process moves to step (2800), the shape of the cursor is changed to a pointer P for specifying a range, and if rNOJ, the process moves to step (2800). (310

Note that after scrolling and movement of concrete figures have started in step (3400), the GO/5TOP key (36
) or any other key is pressed, the scrolling and movement of the concrete figures are stopped.

As is clear from the above, when composing a picture on the screen of the monitor (8), the abstract figure key (22) and the concrete figure key (23) are used to select a desired figure that is moved as a cursor until confirmed. So that you can visually check the shape,
In addition, the color specification key (21) for specifying the color of the figure selected by these keys is also a visually distinguishable key so that you can visually confirm what color it is. As a result, shapes and colors can be selected instantly, which simplifies the process of composing a picture. Furthermore, as shown in Figure 3, one operation panel is equipped with a sheet switch that displays graphic patterns and colors, so you can easily display graphics without actually displaying them on the screen of the monitor (8). While viewing the colors and shapes displayed on each sheet switch, the user can thoroughly consider what kind of picture should be composed of what colors. Furthermore, since the analog joystick (10) is used in the above example, it is possible to speed up the response and improve the accuracy of the position on the tube surface.

In the above example, the selection of figures and the selection of colors may be performed in any order. Furthermore, although the case where the image is displayed on the screen of the monitor (8) has been described, the same effect can be obtained when the image is displayed on the display surface of, for example, a liquid crystal display.

Further, the present invention is not limited to the above-described embodiments, and it goes without saying that various other configurations can be taken without departing from the gist of the present invention.

〔Effect of the invention〕

According to the present invention described above, the shape of the cursor on the screen of the display device is set to a desired character pattern using the character selection button, and the color of the selected character pattern is set to the desired color using the color specification button, and the cursor is changed to the desired character pattern using the character selection button. Since the cursor moving means is used to move the cursor to a desired position on the screen and the character pattern corresponding to this cursor is fixed at this desired position on the screen, it is possible to select the desired character and the color of the selected character. Easy to choose, and
It is easy to understand (and has the benefit of improving the creation of pictures on the screen).
