Description

[Detailed Description of the Invention] (1) Object of the Invention The present invention relates to a multi-window screen display method and document editing device that have a plurality of display areas (windows) on the same screen, and in particular to a display with a restricted size. The present invention relates to a screen display method and device suitable for interactive document editing processing using a screen.

(2) Known Technology In recent years, systems such as word processors that create and modify documents through interactive processing with computers have come into widespread use. In this case, it is desirable to display one entire page of document information to be handled on the screen because it facilitates document processing operations. However, such so-called full-page displays are expensive, so, except for special cases, the common method is to display only a portion of the document and add a scroll function to select the display area. . In particular, in order to handle complex documents containing a mixture of Chinese characters and images, such a partial display method is used due to the limitations of display resolution. Of course, in order to display the entire document information on one screen, it is necessary to handle macro data that is a simplified version of the original document information, such as a reduced image of the book or a document layout diagram using line drawings. At this time, detailed information of the document (part of the document) and overall information (part of the document)
The conventional methods for displaying (macro data) are to switch the display content on the screen along the time axis, or to display detailed information and overall information separately on multiple displays. The former method has the problem that if an arbitrary time section is taken, only either detailed information or overall information is displayed, making it difficult to correlate the two, and the latter method requires expensive equipment.

(3) Purpose of the Invention The purpose of the present invention is to provide a multi-window screen display method and document editing device that can efficiently and economically perform interactive processing of complex document information containing a mixture of Chinese characters, images, etc. It is in.

(4) General description of the invention In order to achieve the above object, the present invention (a) divides a display screen into a plurality of display areas (each of which is referred to as a window), and (b) displays a target document. Overall information (macro data)
is displayed in one window, detailed information of a part of the document is displayed in another window (the former is called a full display window, and the latter is called a partial display window), and (c) The present invention is characterized in that when an input operation for editing document contents is performed, the editing result is reflected in both the whole display window and the partial display window in conjunction with each other.

According to a preferred embodiment of the present invention, furthermore, (d) a rectangular frame or the like is placed at a corresponding position in the full display window to indicate which part of the original document detailed information is displayed in the partial display window. When an input operation is performed to display the mark and scroll the contents of the partial display window, the display position of the mark in the whole display window changes in conjunction with the change in the display contents of the partial display window. It is characterized by being able to move.

According to the method of the present invention, by operating a keyboard or the like, it is possible to select and move the position on the original document where a portion is to be displayed, and also to specify the size of the window and the display position on the display.

Furthermore, in the present invention, the display contents of each window for partial display and full display are always displayed in correspondence without contradiction. For example, when performing document processing such as inserting, deleting, or correcting characters on a partial display window, not only the contents of the partial display window but also the contents of the entire display window are updated at the same time. Conversely, the same applies when processing such as changing the document layout is performed on the entire display window.

As mentioned above, the basic concept of the present invention is to efficiently process documents by treating one display as multiple displays and displaying the entire document information and partial displays in parallel. and,
It is economically viable.

FIG. 1 explains the concept of the present invention.
In the figure, 1 is target document information, which is reduced and displayed in the entire display window 2 of the display. Further, detailed information of a portion of the document information 1 is cut out and displayed in the partial display window 4. At this time, the contents of partial display window 4 are
To indicate which part of the original document it corresponds to,
A rectangular frame 3 is placed at the relevant position in the entire display window 2.
Display. In Figure 1, we have explained the case where a reduced image of the original document is displayed in the full display window.
Instead of a reduced image, it is also possible to display a layout diagram symbolically expressed using line figures or the like.

(5) Embodiments of the invention and their effects An embodiment of the invention is shown in FIG. In the figure, 10 is a processing device such as a microprocessor, 11 is a main memory that stores programs and tables, 12 is an input keyboard, 13 is a file device that stores document information, 14 is a device that reduces image data, and 15 is a An image memory for editing document information, 16 a font memory for storing character fonts, 18 a display, and 17 a bitmap memory for the display 18.

The functions of each device shown in FIG. 2 are as follows.
When the name of document information to be displayed on the display 18 is specified using the input keyboard 12, the file device 13 is searched for the corresponding document information. Document information generally consists of characters and images. Among these, for characters, the corresponding font pattern is read out from the font memory 16, and the character is stored in the image memory 16.
Write in 5. Further, for the image, data read from the file device 13 is written into the image memory 15. In this way, the document information is edited into one piece of image data on the image memory 15 using character and image data. The image memory 15 consists of two areas A and B, and the above editing process is performed in the image memory 1.
Perform this in area A of 5. When this process is completed, the image data on area A is reduced by the reduction processing unit 14 and written into area B of the image memory 15. In other words,
The image memory 15 stores the original image of the document and its reduced image in areas A and B, respectively.

The bitmap memory 17 is a memory that stores display data for each pixel of the display 18. The image data on the image memory 15 is transferred to the bitmap memory 17. The image memory 15 stores a reduced image and an original image of the document, and among these, data of the reduced image is transferred to an area corresponding to the entire display window in the bitmap memory 17. Further, as for the original image on the image memory 15, a partial image is cut out and transferred to an area corresponding to the partial display window in the bitmap memory 17. At this time, in order to clearly indicate which part of the original image the cut out partial image corresponds to, a rectangular frame is written superimposed on the reduced image on the entire display window of the bitmap memory 17. Since the contents of the bitmap memory 17 are displayed on the display 18, the multi-window screen shown in FIG. 1 is obtained.

In order to define the screen configuration of the display 18, a screen definition table as shown in FIG. 3 is provided in the main memory 11. This screen definition table defines the positions and sizes of the entire display window and partial display windows on the screen, and also determines the cropping position of the partial display window from the original image in the image memory 15. be. The size cut out from the original image is made to match that of the partial display window. FIGS. 4 and 5 explain the parameters set in the screen definition table. As shown in FIG. 4, the positions of the entire display window 51 and the partial display window 52 are
It is expressed in coordinates with the upper left corner of 0 as the origin. Further, as shown in FIG. 5, the original image 6 in the image memory 15
The cropping position from 0 is expressed by coordinates with the upper left corner of the original image as the origin, and the size of the cropping area 61 is equal to that of the partial display window.

The main memory 11 also has a search table shown in FIG. The search table is a table showing the correspondence between document names, storage addresses, data lengths, etc. for document information stored in the file device 13.
The document information accumulated in the file device 13 is
As shown in the figure, it is composed of format data, character data, image data, etc. Among these, the format data defines the format of the document, such as character pitch (row and column spacing), top, bottom, left, and right margins. Character data constituting a document is stored in the file device 13 as a string of data encoded in character codes.
Further, image data is expressed by attributes such as its size, data length, and composition position on a document, and the density value of each pixel.
