Abstract

PURPOSE:To reduce the trouble and time for character pattern generation beyond comparison by generating a character pattern which is different in the number of divisions according to image data inputted for the character pattern generation. CONSTITUTION:This system consists of a central processing unit 1 and a main storage device 5 which are required to execute a program in an external storage device 4 where the program and data are stored, and a keyboard 6, an image input device 3, a display device 2, and a printer 7 for the input and output, and display of the data. The image data for generating the character pattern is inputted from the device 3 and expanded on the device 5. Then a parameter is inputted on the keyboard 6 to generate a dot pattern of specified size, which is outputted to the devices 2 and 7. The trouble and time are reduced greatly as compared with a method which position and specifies a cursor on a display in dot units.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the creation of character patterns, and in particular to the creation of a character pattern with a specified number of dots based on image data stored in a main storage device inputted from an image input device. This paper relates to a character pattern generation method using image input.

[Conventional technology]

Conventionally, in this type of character pattern creation method, it is necessary to position and specify the cursor for each dot on the display device to specify the character or special character pattern to be created, as shown in Figure 4. It took a lot of attention and a long time to create.

[Problem to be solved by the invention]

In the conventional character pattern generation method described above, the characters are specified in units of dots on the display device, so creating the pattern requires great care and takes a long time, resulting in a great deal of physical and mental exhaustion. There are drawbacks.

[Means to solve the problem]

The character pattern generation method using image input of the present invention is as follows:
An external storage device for storing programs and data, a central processing unit and a main storage device necessary for executing the programs stored in the external storage device, and a keyboard/keyboard for outputting and displaying data during the execution of the program. Including image input device, display device, printing device,
The apparatus includes a character pattern module that generates a character pattern having a different number of divisions from image data on the main memory inputted from the image input device.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention, FIG. 2 is a block diagram showing the software configuration of an embodiment of the present invention, and FIG. 3 is an explanatory diagram showing an example of characters to be input.
FIG. 4 is an explanatory diagram showing an example of characters to be output.

Referring to FIG. 1, a central processing unit 1 controls all the devices, and a display device 2 displays generated patterns and the like. Reference numeral 3 denotes an image input device, which is a device for inputting an image for generating a pattern. 4 is an external storage device for storing data and programs, and a pattern file for storing generated character patterns also exists here. 5 is a main storage device, 6 is a keyboard, and 7 is a printing device.

FIG. 2 shows the relationship between the modules of the program that implements the present invention and the data on the main memory, where 11 is a pattern generation main module, 12 is an image data input module, 13 is a character pattern generation module, and 14 is a pattern generation main module. This is a pattern file update module, and 5 indicates a main storage device. Figures 3 and 4 explain the method of generating a character pattern from image information, and Dl shows how the image memory is divided so that image information of m dots square can be converted into a dot pattern of n dots square. Show, D
l indicates a character pattern of n dots square. Furthermore, the fourth
As seen in the figure, this is an example showing how a pattern is generated dot by dot on a conventional display, and this also coincides with an example in which a character pattern is generated from an image and displayed on a display according to the present invention. In FIG. 3, portions that are originally filled in are indicated by hatching.

Next, the operation of an embodiment of the present invention will be explained.

Referring to FIG. 1, image data to be generated as a character pattern is inputted by the image input device 3 shown in the same figure, and is developed on the main memory device 5.

A dot pattern of a specified size is generated from the developed image, displayed on the display device 2, and outputted to the printing device 7 at the same time. Parameter input is performed using the keyboard 6. FIG. 3 shows an example of image data to be generated as a character pattern. Regarding this, by performing the processing shown in FIG. 2 using the apparatus group shown in FIG. 1, the dot pattern shown in FIG. 4 is generated.

FIG. 2 shows the relationship between the module of the present invention and the image data character pattern on the main storage device 5. The image data inputted by the image data input module 12 is developed on the main storage device 5. The character pattern generation module 13 generates character patterns from image data using the following method. As shown in Figures 3 and 4, when the size of the image is m dot square consisting of m pixels divided vertically and horizontally, and the size of the graphic pattern is n dot square, the image is divided into m/n dot square. As shown in Dl in FIG. 3, 1.
1.1.2, 1.3. ....

Matrix element numbers n and n are assigned, and if even one dot in each element is on, the corresponding dot of the character pattern indicated by Dl is turned on. Pattern file update module 1
4, the character pattern created by the character pattern module 13 is registered in the pattern file in the external storage device 4.

In addition, in the above explanation, all explanations were made using letters, but even if they have a graphic shape as shown in Figure 3, if they fit in one font, only the shape is different and the other things are considered to be the same. Therefore, patterns can be generated using the same method as characters.

[Effects of the Invention] As explained above, the character pattern generation method using image input according to the present invention generates character patterns based on image data input when generating character patterns, so it is different from the conventional method of specifying each dot. This has the effect that the labor and time required to create a comparison pattern can be reduced to an incomparable degree.
