Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device that displays a predetermined display pattern using a plurality of display elements arranged in a matrix.

[Prior Art] In recent years, display devices with light emitting diodes and the like arranged in a matrix have been used to display advertisements and messages that are rich in variety in both content and visual appearance, including not only letters and texts but also color graphics. It's coming.

At that time, this type of device not only conveys information accurately, but also needs to be able to attract the attention of people and customers. Display is performed in various ways, such as color inversion display.

By the way, in this type of conventional display device, what is displayed on the display board is the display pattern of only one mode, and based on that, the above-mentioned scrolling,
It was giving processing such as blinking.

[Problems to be Solved by the Invention] Therefore, conventional display devices cannot display images in which a plurality of display patterns are superimposed. In other words, the movement of the display pattern and display processing commands are performed on the entire display data waiting in the buffer, so the pattern that appears on the display board shows the same movement as a whole. For example, if one part of the display board is fixed at that location and another part is superimposed on top of it and scrolled, or if scrolls are scrolled facing each other from opposite directions, collisions may occur. I can't continue scrolling by overlapping the images as they are.

For this reason, when you want to convey a relatively long message while emphasizing symbols and symbols, conventional devices
The only way to do this is to insert marks and symbols here and there in the message, and on the receiving side, the message becomes intermittent and difficult to understand, and the marks and symbols do not leave much of an impression, which is a big disadvantage in the end. I was unable to communicate this effectively.

[Means for Solving the Problems] The present invention has been made to address these problems, and includes a first image creation means for creating and storing a display pattern image, and a display pattern stored by the first image creation means. A second image creation means for creating and storing different display pattern images separately from the image, and a destination screen creation for selecting or synthesizing the display pattern images stored in the first and second image creation means. equipped with means. As a result, display patterns in two modes that can be displayed separately and independently without interfering with each other are created, and by combining the two modes, it is possible to display an overlay of images in which different patterns are superimposed.

[Example〕 Examples thereof will be described below with reference to the drawings.

In addition, as a communication function, the created display software editing data is sent to the P and U via the R8232C interface.
.

Next, FIG. 4 is a block diagram showing the flow from creating display software data to actually displaying it on the display board.

21 is a first image creation means for creating a base screen of a display pattern when creating display software in the display data editing system shown in FIG. 3;
is a second image creation means for creating an overlay screen of a display pattern, and these are all composed of a personal computer 15, a color CRT 16, and an image scanner 17.
It consists of

Here, the base screen and overlay screen will be explained.

The final display pattern developed in the VRAM, that is, the destination screen (hereinafter referred to as the DST screen), is composed of these base screens and the overlay screen, and both should be displayed independently without interfering with each other. is possible. In other words, they are two different types of display software. For example, when displaying a certain sentence overlaid on a graphic representing a landscape such as a mountain or the sea, the graphic representing the landscape is the base screen, and the graphic representing the landscape is the base screen, and the graphic representing the landscape is the base screen. The text becomes an overlay screen. . Therefore, the first image creating means and the second image creating means in FIG. 4 are means for independently creating display software. However, the base screen and overlay screen are not strictly defined, but are so-called indexes that the creator uses to distinguish between them. Here, we return to FIG. 4 again.

The base and overlay screens created by the first image creation means and the second image creation means are combined in the destination screen creation means 23, which includes a personal computer 15 and a color CRT 16, and the DST screen of the final image is Create. The DST screen is expanded to the VRAM 14, and the driver controller 8
, is actually displayed as a display pattern on the display board 5 via the drive circuit 4.

Next, FIG. 5 is a flowchart illustrating the flow of creating display software.

The display data editing system is started up, and the first step is to select whether to perform overlay display (1). When performing overlay display, the first image creation means creates display software for the base screen (
2). (The specific steps for creating this display software will be described later.) After completing the creation of the display software for the base screen (3).

The completed display software is memorized (4). Next, display software for an overlay screen overlaid thereon is created by the second image creation means (5). When the creation work is completed (6), the display software is memorized as described above (7). Next, based on the two types of display software created and memorized up to this point, select again whether you want to combine them and display them as an overlay (8). If you choose to do so, create a composite image in the destination screen creation means. Creating a composite image (9) In this case, creating a composite image involves actually superimposing the base and overlay display software created separately on a color CRT, and changing the position of each character or graphic. The final display pattern, that is, the image of the DST screen, is created by It shall be recognized and decided upon. However, it does not create one composite display pattern;
The only thing left to do is to change each display software to match the ST screen. Next, put the display software on standby in the buffer, create a DST screen (1G), and then convert the DST screen to V
Transfer it to RAM (11) and finish creating the display software. Also, if you cancel the overlay display in step (8), the destination screen creation means will
Creating a DST screen based on the base screen 12
), jump to step (11). Furthermore, if you do not select overlay display in the first step (1), no overlay screen display software will be created.
In the first image creation means, create only the display software for the base screen (13), and once it is completed (14)
), create a base screen DST screen based on it (15), and jump to step (11).

Next, the specific steps for creating the display software performed in steps (2) and (5) in FIG. 5 will be explained based on the flowchart in FIG. 6.

When the first or second image creation means confirms that the font buffer is empty (16), the display board 5
The range of the graphic area and character area is set according to the size of (17). Then, read the mark or picture to be displayed using the image scanner 11, and place it within the graphic area set in step (17) on the 16x16 display panel that makes up the display board.
It is developed into a font that corresponds to dots (18). Then, create display text in the remaining character area (19), check that the command buffer is empty (20), create display commands and their sequences such as scrolling, color inversion, and blinking (21), and exit (21). 22).

[Effects of the Invention] The present invention is configured as described above, and has the following effects.

a first image creation means for creating and storing a display pattern image; a second image creation means for creating and storing a display pattern image different from the display pattern image stored by the first image creation means; , and destination screen creation means for selecting or synthesizing display pattern images stored in the first and second image creation means, so that overlay display of images in which different patterns are superimposed can be performed. Therefore, if you want to convey a relatively long message while emphasizing symbols and symbols,
It is possible to keep a symbol mark or sign fixed at a certain location and scroll to display text related to it, superimposing it on top of it, making it possible to display text continuously both semantically and visually. . Therefore, it is possible to sufficiently convey the content of the displayed text while leaving an impression of the marks and symbols on the viewer, and effective and versatile display can be performed.
