Embodiments of the present invention (hereinafter referred to as embodiments) will be described below with reference to the drawings.

FIG. 1 is a view showing a display example of a page editing processing user interface in the document editing apparatus according to the present invention.

In FIG. 1, a page edit window 10
At 0, icons representing pages constituting the document to be edited are arranged in a raster scanning order as indicated by A in the figure according to the page order, and are displayed in a list. Here, each page that is a component of the document is called a real page to distinguish it from a virtual page described later. FIG. 1 shows a display example of a document including six real pages 110. The icon of each real page 110 is a reduced image obtained by reducing the image of the actual page at a fixed scale, and the user can identify each page by this icon.

In this embodiment, the user can specify a page to be edited or moved, such as moving or deleting, by selecting an icon with a pointing device such as a mouse. In addition, in an editing process that involves inserting a page into a page array, such as adding, moving, or copying a page, the position of the insertion destination (that is, the addition destination, the movement destination, the copy destination, etc.) is indicated by the icon of the page. Can be specified by selecting.

As a method of designating the insertion destination position,
A method to specify the page after the position where you want to insert,
There is a method of designating the page immediately before the insertion position, but the former will be described as a representative here. That is, in the example of FIG. 1, the insertion target page such as the additional page or the moving page is inserted before the page selected as the insertion destination. When the insertion destination of the page is specified by such a method, as pointed out as a problem of the related art, an operation method for inserting a page after the last page 110a becomes a problem. On the other hand, in this embodiment, the virtual page 11 is placed behind the last page 110a.
With the introduction of No. 2, it is possible to specify the page insertion destination at the end of the last page (that is, at the end of the document) by exactly the same operation as at the other positions.

That is, in this embodiment, the icon of the virtual page 112 is displayed after the icon of the last page 110a of the series of real pages 110, and the virtual page 112 is selected as a destination to which the page is added or moved. In this case, a page to be added is inserted before the virtual page 112, that is, at the end of the document.

FIG. 2 is a diagram showing an example of such an operation. In the page arrangement shown in (a), for example, if page D is selected with a mouse and this page D is brought to the position of virtual page 112 by drag and drop, as shown in (b), page D becomes a document Can be moved to the end. If you want to move page D to the beginning of the document, drag page D and drop it at page A.

As described above, according to the present embodiment, in the page editing user interface, since the icon of the virtual page 112 is introduced after the icon of the last page 110a of the document, However, from the user's point of view, the page is inserted at a position before the selected icon, and the page insertion destination can be selected with the same operation feeling.

Next, a description will be given of an apparatus configuration and a processing procedure for realizing the above operation.

FIG. 3 is a functional block diagram showing the configuration of software for realizing the document processing apparatus of the present embodiment.

In FIG. 3, an input processing unit 10 interprets an event group generated by an input from a mouse or a keyboard as an editing operation, and passes the interpretation result to an editing processing unit 20. The edit processing unit 20 executes a process such as editing a page array based on the interpretation result. The edit processing unit 20 has page array management information 22 as information for managing the page array of the document to be edited. The page arrangement management information 22 includes an arrangement in which page IDs of respective pages are arranged in the order of page numbers. The page ID is an identification number uniquely assigned to each page, and a desired page can be specified using the page ID. The page-by-page editing process such as adding or moving a page is realized by adding a page ID of a new page or changing the arrangement order of the page IDs in the page arrangement management information 22. The page array management information 22 may be constructed using any data structure. The edit processing unit 20 manages the file name of a file describing the substance of the page and page attribute information such as the size of the page in association with the page ID, and refers to this information from the page ID. Thus, an image, an attribute, and the like for each page can be obtained. The editing processing unit 20 creates and manages a selection list 24 as temporary management information for editing processing. This selection list 2
4 will be described in detail later.

The display processing unit 30 creates a display image as shown in FIG. 1 by referring to the page arrangement management information 22 of the editing processing unit 20, and displays the display image on a display.

In this embodiment, as a method for performing operations such as adding, moving, and copying a document, a method using command selection (hereinafter, referred to as a “command method”), a drag-and-drop method, and the like.
Two types of operation methods, a method using a drop (hereinafter referred to as a “drag method”), are provided. The command method first specifies pages to be added, moved, copied, etc.
Then, a desired processing command is selected from a pop-up menu or the like, and a page such as a destination or a copy destination is selected as necessary. On the other hand, the drag method is an operation method in which a mouse button is pressed to select a page, and the page is dragged to a target position and dropped as it is. This method can be used for moving or copying a page.

The processing procedure of this embodiment will now be described with reference to FIGS.
This will be described with reference to FIG.

FIG. 4 is a flowchart showing a processing procedure for selecting a processing target page, a destination, and the like. This processing is common to both the command method and the drag method. First, the input processing unit 10 constantly monitors the state of the left mouse button (S10), and when detecting the pressing of the left mouse button, the position of the mouse pointer on the screen at that time is on the real page. Is determined (S1
1). If the result of this determination is Yes, it is recognized that the real page has been selected, and it is further determined whether or not the control key of the keyboard has been pressed (S12). The control key is a key used when a plurality of pages are specified as a processing target or when a page once specified as a processing target is excluded from the specification. Therefore, when the control key is not pressed, the 1 pointed by the mouse pointer
This means selecting only one real page. Then, the editing processing unit 20 clears the selected data up to that time (S1).
3) Add the actual page to the selection list 24 (S1)
4). Here, the selection data is a generic name for the selection list 24 and a virtual page selection flag described later. The selection list 24 is a list in which the page numbers of the real pages selected in the processing of FIG. 4 are registered according to the selection order. The virtual page selection flag is a flag having two states of TRUE and FALSE. When a virtual page is selected, the virtual page selection flag is set to TRUE. The selection data clearing process of step S13 is a process of deleting all the entries of the selection list 24 and resetting the virtual page selection flag to FALSE. The process of adding to the selection list 24 in step S14 is a process of adding the page number of the real page pointed by the mouse pointer to the end of the selection list 24.

If the depression of the control key is detected in step S12, the editing processing unit 20 determines whether or not the real page specified by the mouse pointer is registered in the selection list 24 (S15). . This judgment is Y
In the case of es, it is interpreted as an instruction to deselect the page once selected, and the page number of the real page is deleted from the selection list 24 (S16). Step S15
If the result of the determination is No, it is interpreted as a selection of a new page, and the page number of the real page is added to the selection list 24 (S14).

The processing for selecting a real page has been described above. In the present embodiment, in addition to the case where a real page is selected as a target of processing such as movement or copying, the position of an insertion destination for inserting a page to be subjected to such processing is added in processing such as addition, movement, or copying. Selected to direct. The processing procedure shown in FIG. 4 is common to both cases. Whether the page registered in the selection list 24 is interpreted as a processing target page or interpreted as designation of a page insertion destination is determined by subsequent input contents.

If it is determined in step S11 that the mouse pointer is not on a real page, the input processing unit 10
Determines whether the position of the mouse pointer is on the virtual page (S17). If the result of this determination is Yes, the editing processing unit 20 sets the virtual page selection flag to T
Set to RUE (S18).

If the result of the determination in step S17 is No, the mouse pointer is located at a place other than the icons of the real page and the virtual page. In this case, the selected data is cleared (S19). The specific contents of this processing are the same as in step S13.

After a page is selected by such a process, a process for the selected content is instructed by either the drag method or the command method described above. Hereinafter, a detailed processing procedure will be described for each of the drag method and the command method.

FIG. 5 is a flowchart showing the processing contents in the case of the drag method. If the mouse is dragged while the page is selected by pressing the mouse button in the page selection process of FIG. 4, the mode shifts to the drag mode. However, if the virtual page is selected, the mode does not shift to the drag mode even if the drag is performed. In the process shown in FIG. 5, the input processing unit 10 determines whether the current state is the drag mode (S20), and monitors the release of the mouse button in the drag mode (S21). When the release of the mouse button is detected, it is determined whether or not the position of the mouse pointer at that time is on a real page (S22). If the determination result is Yes, the editing processing unit 20 inserts the page registered in the selection list 24 before the actual page at the position of the mouse pointer (S23). That is, the editing processing unit 20 inserts the page ID of the page registered in the selection list 24 into the position of the page ID of the page sequence management information 22 at a position before the actual page at the position of the mouse pointer.

In the case of this drag-type processing, whether a page is moved or a page is moved by pressing a specific key before the drop is selected. Alternatively, before the page is selected, it is possible to select from a menu or the like whether the process to be performed is a page move or a page copy.
In this case, one of the processes may be set as a default process. Step S in case of page movement
At 23, a page is inserted and a selection list 24 is displayed.
Is deleted from the page arrangement management information 22. In the case of page copying, such deletion processing is not performed.

If it is determined in step S22 that the mouse pointer is not on a real page,
Further, it is determined whether or not the position of the mouse pointer is on a virtual page (S24). If the result of this determination is Yes,
The pages included in the selection list are stored in the page arrangement management information 2
In step 2, it is inserted after the last page (S25). In addition, in the case of the page movement mode, together with this insertion processing,
The process of deleting the page registered in the selection list 24 from the page array management information 22 is performed.

As described above, in step S23 or S25
When the page insertion process in is completed, the drag mode ends (S26). If the determination result in step S24 is No, it is determined that no valid designation of the page insertion destination has been made, and the drag mode is ended (S2).
6).

In steps S23 and S25, the description in parentheses () is a processing procedure in the document editing apparatus that inserts a page after the page specified as the insertion destination. Will be described.

Next, processing contents in the command method will be described. The operation input by the command method can be used for any of adding, moving, and copying pages.

In the case of page addition, the user selects a page addition command by an operation such as clicking a mouse from a pop-up menu or the like. Then, when the mouse pointer is moved to a desired destination page and the mouse button is clicked, the editing processing unit 20 inserts a new page before the page selected by the click. In terms of internal processing, the edit processing unit 20 assigns a page ID to a new page, and inserts this page ID in the page arrangement management information 22 in the order before the selected page. Thereafter, an editing process is performed on the newly added page.

In the command-type operation, the page moving process is realized by a so-called cut-and-paste operation. In this case, the user selects a page to be moved in the page selection process shown in FIG. 4, and then selects a cut command from a pop-up menu or the like. Then, the page registered in the selection list 24 becomes the page arrangement management information 2
2 and the data of those pages is registered in the clipboard. Thereafter, when the user selects the destination of the page by the selection processing of FIG. 4 and further selects a paste command from a pop-up menu or the like, the page registered on the clipboard is inserted before the page selected as the destination. You.

The procedure of the paste command processing will be described in more detail with reference to FIG. When the paste command is selected, the editing processing unit 20 determines whether a page is registered in the selection list 24 (S30). If there is a page registration, the page is interpreted as a page insertion destination. Therefore, the editing processing unit 20 performs step S
If the determination result in Step 30 is Yes, it is checked whether or not the page is registered in the clipboard (S31). If the page is registered, the page data is extracted from the clipboard (S32), and the page is managed in the page arrangement. The information 22 is inserted before the page specified as the insertion destination (that is, the first page of the selection list 24) (S3).
3). If a plurality of pages are registered on the clipboard, all of these pages are inserted. It should be noted that the reason why the first page of the selection list is recognized as the page insertion destination in step S33 is to consider a case where a plurality of pages are registered in the selection list 24 at the time of pasting.

If there is no page in the selection list 24 in step S30, the editing processing unit 20 determines whether or not the virtual page selection flag is TRUE (S34). If this flag is TRUE, the editing processing unit 20 interprets that the virtual page is specified as the insertion destination, extracts the page data from the clipboard (S35), and stores these pages in the page arrangement management information 22 in the page arrangement management information 22. It is added after the last page (that is, at the end of the page array) (S3
6). If the determination result of step S34 is No, the editing processing unit 20 interprets that the insertion destination of the page is not specified, and ends the processing without performing any operation. In steps S33 and S36, the description in parentheses () is a processing procedure in the document editing apparatus that inserts a page after the page specified as the insertion destination, which will be described later. .

The page moving process is realized by such a cut and paste process.

The page copying process is realized by a so-called copy and paste operation. This processing may be exactly the same as the above-described page movement processing except that the page selected as the target is not deleted from the page arrangement management information. That is, after selecting the page to be copied in the selection processing of FIG. 4, the user may select a copy command from a pop-up menu or the like, select a copy destination in the selection processing, and then select a paste command. Unlike the cut command processing, the page registered in the selection list 24 is not deleted from the page arrangement management information 22 in the copy command processing. The paste processing may be exactly the same as the above-described page movement processing. For example,
In the case where pages A and C are selected as copy targets in FIG. 8A and the virtual page 112 is selected as a copy destination, the above-described processing causes the last page D to be copied as shown in FIG. 8B. Later pages A and C are copied.

In the above, the procedure of the editing process according to the user's operation has been described. The display of the user interface screen on which such editing processing is based is performed according to the procedure shown in FIG. The display processing unit 30 stores the page arrangement management information 2
2, the first page is taken out (S40). If the page exists (S41), a reduced image of the page is drawn as an icon at a predetermined position in the upper left corner of the window and displayed (S42). At this time, a display such that the page is registered in the selection list 24 and a case where the page is not registered are displayed such that the two can be distinguished from each other. When the drawing is completed, the next page is extracted from the page array management information 22 (S43), and the icon is drawn at the position of the next page on the window. Then, when the display of the last page is completed, the determination result of step S41 becomes No, and the process proceeds to a virtual page icon display process. That is, the virtual page selection flag is checked (S4
4) If it is FALSE, the virtual page icon is displayed in the normal display mode at the position next to the last real page icon (S45). On the other hand, if the virtual page selection flag is TRUE, the icon of the virtual page is displayed in the display mode at the time of selection, such as reverse display (S4).
6). The size of the icon of the virtual page may be the same as the size of the icon of the real page, or may be a fixed size. If the document includes real pages of different sizes, the icon of the virtual page can be displayed according to the maximum size or the minimum size of the real page icon, whichever is set.

The display processing section 30 executes the above processing every time an event such as selection or movement of a page occurs.

As described above, according to the present embodiment, even when a page is inserted at the end of a document in a document processing apparatus that inserts a page before a page selected as a page insertion destination, The user can specify the insertion destination by performing exactly the same operation as when performing insertion at another position.

The present invention is of course applicable to a document processing apparatus of a type that inserts a page after a page selected as a page insertion destination. In this case, as shown in FIG. 9, the icon of the virtual page 112 is displayed before the first page 110b of the real page 110, and the virtual page 11 is displayed.
When 2 is specified as the page insertion destination, the configuration may be such that a page is inserted before the first page 110b. Regarding the process of the document editing apparatus in this case, the page selection process can use the procedure shown in FIG.
Further, the cut command processing and the copy command processing may be exactly the same as in the above embodiment. In the drag-and-drop processing of the selected page, the processing shown in parentheses () in S23 and S25 in the procedure of FIG. 5 may be performed. That is, in S23, the page may be inserted after the page at the drop position, and in S25, the page may be inserted before the first page. Similarly, in the paste command process, the process shown in parentheses in S33 and S36 may be performed. In the display process of the page editing window, the icon of the virtual page may be displayed first, and then the icon of the real page may be displayed subsequently.

In the above, the case where the icons of the pages are arranged and displayed in the order of the raster scanning system has been described as an example, but the present invention is not limited to a specific page arrangement display system. For example, the present invention can be applied to a method in which page icons are superimposed and displayed while being slightly shifted as shown in FIG. In FIG. 10, a virtual page 112 is displayed after the real page 110, which corresponds to a document processing apparatus that inserts a page after a page selected as a page insertion destination.

Although the above-described embodiment is an example in which the present invention is applied to a document editing apparatus that performs page-by-page editing, the present invention is not limited to the case of page-by-page editing and may be one-dimensionally edited. It can be easily understood that the present invention can be widely applied to editing processing in which document elements of all levels constituting a document are arranged as a unit. Examples of such a document element include, for example, a page group obtained by grouping a plurality of pages, a chapter and a section.

The document editing apparatus described above can be realized, for example, by causing a computer to execute a program describing the functions or processing procedures described above. In this case, the program is supplied via a recording medium such as a floppy disk or a CD-ROM, or via a communication line, and can be executed by installing the program in a fixed disk device attached to a computer, for example. .
