Abstract

PURPOSE:To make faster the replacement of a picture from an actual dimension displaying to a simply enlarged displaying and from the simply enlarged displaying to a normally enlarged displaying by providing an enlargement processing part to enlargement-process image data due to a character font for the actual dimension displaying and a normal enlarging part to generate the enlarged image data due to the character font for the enlarged displaying, and a switching part. CONSTITUTION:When a normal enlargement instruction 19 is inputted, a switching part 13 is switched to turn off the input of an enlargement processing part 12, and the output of an enlarged image memory 151 of a normal enlarging part 15 is transferred to a frame memory 11b. For this, a simply enlarged picture is erased, and the normally enlarged displaying is executed by a displaying 10c of a display device. When a user desires to update the character by watching contents, he inputs the corresponding character and another character, an enlarged character pattern corresponding to the character is generated from a character font part 153 for the enlarged displaying, and the enlarged displaying after the updating is immediately executed. Thus, the enlarged displaying of the document including graphics and characters from the actual dimension can be made faster.

Description

[Detailed Description of the Invention] [Summary] This invention relates to a WYSIWYG method in an information processing system that includes a display device, a printing device, and a processing device, and inputs graphic and character information, performs processing such as editing while looking at the display screen, and prints. , If an enlarged screen is required when displaying the actual size, the high-speed WYSIwyG method 2 can display an enlarged screen of the image data at high speed, and upon request, display an enlarged image using an enlarged character pattern. W is an information processing system that processes human-generated graphic images and character data using a processing device, displays them on a display device as image data, and prints them out using a printer.
In the YSIWYG system, there is an enlargement processing section that simply enlarges and outputs image data using a character font for actual size display based on an enlargement instruction, and an enlargement processing section that starts at the same time as displaying and outputting image data for actual size display, and outputs the image data using a character font for enlargement display. A regular enlarging section that generates enlarged image data and a switching section that selects the output of the enlarging processing section or the regular enlarging section according to an instruction input and inputting it to the display device are provided. The configuration is configured to quickly replace the screen with enlarged display.

[Industrial Field of Application] The present invention is a WYSIW information processing system that includes a display device, a printing device, and a processing device, and inputs graphic and character information and processes and prints a January collection while looking at the display screen.
YG Method 2: Editing and typesetting of documents to be printed while displaying figures and characters on a display device such as a CRT (cathode ray tube) are performed by a processor, and the resulting display content is printed on a laser printer, etc. Techniques for obtaining printed output using high-density dots have been adopted.

For example, word processors, workstations, disktosopbublinoshing (D, T.

P), Electronic Publishing (EP), Computerized Type Setting (CTS)
Such technology is used in various systems such as.

Recently, BP publishing, which uses computers to perform i-editing and printout of publications such as magazines, product instruction manuals, technical literature, and new publications, has become popular, and EP
Tii! A common method is to collect one sheet of paper on the J side and output the block version using a laser printer.

In that case, in order to improve overall efficiency, it is essential to have the ability to view the image of the block output as it is on the CRT, and this can be expressed in English as What You
"See Is What'y'ou Get", and by combining the initials of each Hayabusa word, it becomes WYSIWY
It is called the function of G.

Publications contain text information and graph ink information such as figures, graphs, and photographs.In order to express this information on a CRT and perform editing work such as checking, moving, and correcting that information, From the viewpoint of man-machine printing, high speed is required, and it is desired to perform WYSIW Y G at high speed.

7. Prior Art] A configuration diagram of Conventional Example 1 is shown in FIG. 3, and a configuration diagram of Conventional Example 2 is shown in FIG. 4.

In FIG. 3, 30 is a CRT display device, 31 is a frame memory, 32 is an image memory, and 33 is a processing device (C
34, 35 is a character pattern memory, and 36 is a laser printer.

To explain the operation of the configuration shown in Fig. 3, images such as figures (including graphs and photographs) and character data information are input manually to the processing device (using a keyboard, magnetic disk, scanner, etc.), The figure is held as image data of 480 dpi (dots per inch) in accordance with the resolution (scanning line density) of the laser printer.

However, character data is held as code data (several bytes each). When outputting to the laser printer 36, the 480 dpi image data of graphics is output as is, and the character data is output to the character pattern memory 36.
Various sizes stored in 5 (various types from 6 to 16 points)
A character pattern of a specified size is extracted from among the characters, and dot data with a density of 480 dpi is output and printed.

On the other hand, the resolution (scanning line density) of CRT30 is usually 120
dpt, and in this conventional example 1, the character pattern memory 34 stores a pattern for one type of character size,
The processing device 33 compresses the graphic image data at a ratio of 4:1 and converts it into 120 dpi image data, and the character data is stored in the character pattern memory 3.
4, the text is converted into a dot pattern of one type of character size (for example, one character is a pattern of 24 dots x 24 dots), the image data of figures and characters is stored in the image memory 32, and the content is displayed on the screen of the CRT 30. One frame is stored in the memory 31 for 120d.
Display is performed by scanning lines of pi. In this case, CRT
The 14 format is simplified by having only one type of character size in the character image memory for display.

Next, the configuration of conventional example 2 will be explained with reference to FIG.

40 to 13.4G and 47 in FIG. 4 correspond to 30 to 32, 33, 35, and 36 in FIG. 3, respectively, and their explanation will be omitted. The difference is that in the case of Conventional Example 2, there is a character pattern memory 45 that generates the same fffi 2p (multiple types) character size as the character pattern output to the laser printer 47 as a character pattern for normal character display, and a character pattern memory 45 that enlarges and displays characters. It is provided with an enlargement character pattern memory 44 for displaying image data of an enlarged font. however,
Since printers and CRTs have different resolutions as described above, the number of dots in digital fonts differs even for characters of the same size.

For example, for 9 point characters, the printer size is 60X.
60 dots, but for C1≧T, 15X for actual size display
15 dots, and 30×30 dots for enlarged display.

To explain the operation of Conventional Example 2, first, the figures etc. are the same as Conventional Example 1.
The image data is converted (4:1) in the same manner as in 42, 71, . -Mmemo 1J41'
A screen display (actual size display) identical in appearance to that outputted to the laser printer 47 is displayed on the CCRT-10.

For example, one A4 size page (corresponding to one page of a printer) is displayed on this display screen, so if the font size is small, it will be difficult to read. becomes difficult. In that case, in the configuration of Conventional Example 2, by instructing enlarged display, it is possible to perform twice enlarged display (naturally, the display area becomes smaller).

Therefore, in this configuration, the enlargement character pattern memory 4
4, which includes a dot pattern twice the size of each character for each character (twice the size of the character pattern memory 46,
That is, pattern data with a resolution of 240 dpi) is stored.

When an instruction to enlarge is given, the process "i1 takes out the enlarged dot pattern of each character data from the enlarged character pattern memory 44 and stores it in the image memory 42. In this case, the image data such as figures etc. Figures etc. are also enlarged and stored in the image memory 42 at the rate of 1) (240 dpi).Then, the image data of the area to be displayed is transferred to the frame memory 41 and CR
An enlarged screen is displayed on T and IO. The user can perform necessary processing such as updating while viewing the enlarged screen.

[Problems to be Solved by the Invention] According to the above-mentioned conventional example 1, since the CRT display image displays only one type of character size, there is a problem that it is different from the image output to the printer. Also, conventional example 2
In this case, although the actual size display provides the same display as the printed image, it is necessary to perform enlargement processing to see the characters more clearly, so screen replacement is performed using a character pattern memory different from that for actual size display. must be done.

However, the problem is that executing this screen replacement requires a considerable amount of processing time due to the processing of a huge amount of data, and during this time the user is waiting in vain for the screen to be replaced. Met.

The present invention is a high-speed WYSIWYG method that can display an enlarged screen of image data at high speed when an enlarged screen is required during actual size display, and display an enlarged image using an enlarged character pattern when requested. The purpose is to provide two methods.

[Means to solve the problem] FIG. 1 shows a basic configuration diagram of the present invention.

10 in Fig. 1 is a display device such as a CRT;
, 10c represent actual size display, simple enlarged display, and regular enlarged display on the display screen of the display device 10, lla and b are frame memories, 12 is an enlargement processing unit, 1
3 is a switching unit, 14 is an image memory, 15 is a normal enlarging unit, 16 is a processing device, and 17 is a printer. The normal enlarging unit 15 includes an enlarged image memory 151 and a processing device 1.
52 and a character font section 153 for enlarged display.

It should be noted that this diagram represents the principle of the present invention, and it goes without saying that the frame memory 11 and the processing units 16 and 152 can each be actually constituted by one device.

According to the present invention, when an actual size display corresponding to one page of printed images is displayed and it is desired to perform an enlarged display, the contents of the image memory used for the actual size display are simply enlarged at high speed by the enlargement processing unit according to an instruction. While processing and displaying the output, the font enlarger enlarges each character according to the enlarged character pattern to generate an enlarged image and stores it in the image memory.When normal enlargement is instructed, the enlarged image is immediately generated. is displayed to enable processing such as updating in an enlarged display state.

[Function] The processing device 16 in FIG. 1 holds image data such as figures and character data input in the same manner as in the past, and stores character patterns of various character sizes for display on the display device 10. A character bakun of the specified character size of the corresponding character is generated from the character font unit 160 and stored in the image memory 14 together with the graphic image. The contents of this image memory 14 are frame memory 1
1a, and is displayed on the actual size display 10a of the display device 10 while being refreshed.

If the user wishes to enlarge and display the displayed content, an enlargement instruction 18 (including an instruction for the enlargement position) is input. When the instruction is received, the enlargement processing unit 12 is driven, and data corresponding to the specified position is extracted from the image data for actual size display in the image memo January 4, and is simply enlarged.

This enlargement process is a conventionally known image processing technique, and its principle is to simply convert the amount of information in each dot into twice the length (double the length in the horizontal direction, This is a process in which the converted output is repeatedly copied and output by scanning in the vertical direction), and because the processing content is relatively simple, the processing speed is high. The simple enlarged image data obtained by the enlargement processing section 12 is transferred to the switching section 13.
frame memory llb (this is actually 11a
), and a simple enlarged display 10b of the display device 10 is output.

At the same time as the enlargement processing by the enlargement processing section 12 is executed, the enlargement instruction 18 causes the regular enlargement section 15 to start generating an enlargement pattern at the designated position. That is, in the processing device 152 (actually the same as the processing device 16), a character pattern twice the size of the original actual size character pattern is generated from the enlarged display character font section 153, and information such as graphics is also twice the size. The image data is converted to the size of , and stored in the enlarged image memory 151 (provided separately from the image memory 14). Note that the generation of an enlarged image using this enlarged display character font is performed by the same technique as the generation of the enlarged pattern in Conventional Example 2.

Users who create and edit documents using this system can
If you look at the simple enlargement display 10b and there is no need to make any changes to its contents, you can simply enlarge it, but if you want to perform update processing such as correcting or deleting part of the content, use the regular enlargement. Enlargement instruction 19 is input. That is, on a simple enlarged screen, characters cannot be manipulated because the coordinate positions do not correspond to the original character data.

When the regular enlargement instruction 19 is input, the switching section 13 switches to turn off the input of the enlargement processing section 12 and turns off the input of the enlargement processing section 15.
The output of the enlarged image memory 151 is stored in the frame memory l.
Transfer to lb. As a result, the simple enlarged screen disappears, and the normal enlarged display is performed on the display 10C of the display device 10. When the user sees this content and wants to update the characters, he manually inputs the corresponding characters and enters another character. When input, an enlarged character pattern corresponding to that character is generated from the enlarged display character font section 153, and the updated enlarged display is immediately executed.

The content updated in this way is the same as before for character data in character pattern memory 1 for 480 dpi i.
61, the image data (data for 480 dpi) is outputted as it is, and the image data (data for 480 dpi) is outputted as it is and printed on the printer 17 as seen on the display at a resolution of 480 dpi.

[Example] A configuration diagram of an embodiment of the present invention is shown in FIG.

In FIG. 2, 20 is a process 8, 21 is a character pattern of various character sizes of 480 dpi for laser printers,
In addition to storing character patterns of various sizes at 120 dpi for actual size display and character patterns of various sizes at 240 dpi for enlarged display, 1. Figures targeted for collection q

It is composed of etc.

To explain the operation of FIG. 2, the mouth shape image and character data inputted by the keyboard 23, magnetic disk device 21, or scanner (not shown) are stored in the memory 201 of the processing device 20.

The data stored in the memory 201 is converted into a dot pattern using the actual size display character pattern in the magnetic disk device 21 for display on the CRT 24, and the graphic image is compressed at a rate of 1/4 and displayed on the terminal. Control bag W122
will be forwarded to.

In the terminal control device 22, the data is stored in one part A of the image memory 225 via a 16-bit bus 227, a raster image processor 223, and a 32-bit image bus 228. Next, the contents of section A of the image memory 225 are transferred to the frame memory 226 and displayed on the CRT 24.

When looking at this display and wishing to enlarge the display, specify the enlargement position (center) from the keyboard 23 (using a known means such as a cursor) and operate the enlargement instruction key. CPU 22 of device 22
1, and the processing program sends the information to the processing device 20, and the CPU 221 gives an instruction to the raster image processor 223 to execute enlargement processing.

As a result, the raster image processor 223 executes a process of simply enlarging a portion of the image data stored in part A of the image memory 225 centered at the designated position at high speed, and the enlarged data generated by the processing is The image is transferred to the frame memory 226 via the image bus 22B and displayed on the CRT 24.

In the processing device 20, the request for enlargement instruction is sent to the terminal control device 22.
When inputted manually, regular enlargement processing is performed on the graphic and character data in the memory 201.

In that case, for character data, the magnetic disk device 21
