DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a display data input device used for a multi-color dot type display board comprising a large number of display elements such as LEDs.

[0002]

2. Description of the Related Art In a conventional display data input device, image data is input from an image scanner, and data of all dots in a desired range of the image data is used as display data of a display board.

A technique for thinning image data is CR
Used in T. However, since this technology is compatible with full color, it cannot be used for a multi-color dot type display board.

[0004]

As described above, in the conventional display data input device, it is necessary to designate the data of all the dots in a desired range of the image data one by one. Therefore, there is a problem that it is difficult to grasp the entire image of the display data until the input is completed, and it takes a long time.

[0005]

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a display data input device in which the entire image of the display data can be easily captured even during the input of the display data, and can be easily input in a short time.

[0006]

A display data input device according to the present invention is for inputting display data to be displayed on a multi-color dot type display board, and includes an image memory unit, a control unit, a thinning processing unit, and a display unit. A data memory unit and the like are provided. The image memory unit stores image data input by the image input device. The control unit sets a frame range of the image data stored in the image memory unit and sets a display range of the display board. The thinning-out unit thins out the data in the blanking range to match the number of dots in the display range. At this time, the thinning processing unit converts one dot of the display range to one dot.
For multiple dots in the corresponding framed area,
The color that is the most common among the colors
The displayable color of the display board closest to the color is the color sample data.
The color of one dot in the display range by selecting
I do. The display data memory unit stores, as display data, the data in the frame extraction range thinned out by the thinning processing unit.
In addition, when the operator designates two points, the blanking range or the display range may be set as a rectangle having the two points as opposed vertices.

[0007] By setting an outline range in advance for image data read by an image scanner or the like, it is easy to immediately grasp the entire image of the display data. In addition, by setting the display range on the display board in advance, it is easy to immediately grasp the entire image of the display data. Further, the thinning of the image data and the designation of the color are automatically performed. Therefore, the entire image of the display data can be easily captured, and the display data can be input easily and in a short time.

FIG. 1 is a block diagram showing one embodiment of a display data input device according to the present invention. Less than,
Description will be made based on this drawing.

The display data input device 10 includes, for example, a microcomputer and an external memory, and includes an image memory unit 12, a control unit 14, a thinning processing unit 16, a display data memory unit 18, and the like. Image memory unit 12
Stores image data input by an image input device such as the image scanner 20 or the video camera 22. Control unit 14
Sets the frame range of the image data stored in the image memory unit 12 and sets the display range of the display board 23. The thinning-out processing unit 16 thins out the data in the blanking range to match the number of dots in the display range. The display data memory unit 18 stores, as display data, the data in the framing range thinned out by the thinning processing unit 16.

The control unit 14 includes a keyboard 24, a CRT 2
6 are also connected, and have a function of controlling the image memory 12, the thinning processing unit 16, the display data memory unit 18, and the like, and a function of exchanging display data and control signals with the external computer 28, and the like. .

The image data read by the image scanner 20 is once received by the control unit 14 and stored in the image memory unit 12 together with file name and address information.

The image data called by the control unit 14 based on the address information is subjected to a thinning process by the thinning processing unit 16 and stored in the display data memory 18 together with a new file name and address information.

When there is a display data read request from the external computer 28, the control unit 14 searches the address information of the display data memory unit 18, calls up the corresponding display data, and stores the called display data and file name. Output to the external computer 28.

FIG. 2 is a flowchart showing an example of the operation of the display data input device 10. FIG.
FIG. 4 is an explanatory diagram showing image data displayed above. FIG.
FIG. 4 is an explanatory diagram illustrating the principle of the thinning processing in the thinning processing unit 16. Hereinafter, description will be made with reference to FIGS.

First, it is determined whether or not a thinning process is to be performed on image data a read by the image scanner 20 or the like or read from the image memory unit 12 (steps 101 and 102). This determination may be made automatically by the control unit 14, or may be made by the operator via the keyboard 24. When performing the thinning process, the operator designates the start point b and the end point c in the image data a displayed on the CRT 26 via the keyboard 24 (FIG. 3). The blanking range d is set as a rectangle having the start point b and the end point c as vertices facing each other (step 103). Further, the control unit 14 determines what the number x and the number of dots of the blanking range d are.

Next, the operator specifies in what range of what number of dots the display board 23 is to be displayed. Thereby, a display range is set (step 104). Subsequently, based on the number of dots in the above-described frame-out range and the number of dots in the display range, m × n-dot m, which becomes one dot after reduction,
n is calculated (steps 105 and 106, FIG. 4).

Further, among the m × n dots, the most frequent color is set as a provisional color after thinning. The color after reduction is determined by selecting the displayable color of the display board 23 closest to the temporary color from the color sample data (step 10).
7). All the dots after this color designation processing has been reduced (FIG. 4
(For each unit A) (step 108). The display data thus obtained is stored in the display data memory unit 18 with the file name and address information added thereto (step 109). If there is an instruction from the external computer 28, the display data is called from the display data memory unit 18 and transmitted to the external computer 28.

The frame range of the image data is not limited to a square, but may be a circle or the like. In this case, the display range of the display board is always circular or the like.

[0019]

According to the display data input device according to the present invention, the entire image of the display data can be set by previously setting the outline range of the image data or the display range on the display board. It can be grasped immediately. Further, the operator only has to specify the frame removal range and the display range. Therefore, display data can be input easily and in a short time.

According to the display data input device according to the second or third aspect, since the operator can set the frame-out range or the display range only by specifying two points, the display data can be input more easily.
