Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an electronic device, a display control method, a program, and a recording medium, for example, a selection range display method, a selection range display device, a program, and a recording medium suitable for use in editing character information such as a word processor or a text editor.
[0002]
[Prior art]
Today, with the improvement in the performance of information processing devices such as personal computers, it is common to edit sentences by digitizing them. Such editing functions can be provided to personal computers, portable information terminals, and mobile phones. Various application programs are widespread.
[0003]
By the way, one of the operation techniques of the above-mentioned editing function is “selection operation”, which is performed when an arbitrary editing operation is performed on a character string or a graphic in a document (document data). This is an operation to specify the part explicitly.
FIG. 15 shows a conventional editing screen, but shows a state in which already input document data (there is no particular significance in the contents) is displayed on the editing screen 1.
In this state, when a part of the document data is selected and some editing is to be performed on the selected part, for example, a change, deletion, or movement of a character attribute is to be performed, the operator needs to start (or end) the target character string. Select a character and drag the cursor to select the last (or first) character of the target string. With this operation, the selection range 2 (that is, from the beginning to the end of the target character string) is highlighted (or identified and displayed by another method), and the selection range 2 is clearly displayed on the screen.
[0004]
[Problems to be solved by the invention]
However, in the case of such a conventional “selection operation”, for example, as shown in FIG. 16, if the selection range is wider than the display screen such that the selection range 3 extends to the next page, screen scrolling or page movement is performed. The editing screen 4 including the start portion (“Yowamushi ...”) of the selection range 3 and the editing screen 5 including the end portion (“... accepted”) are different from each other. There is. Therefore, the operator cannot see through the entirety of the selection range 3 at a time, so the operator must remember the start position of the selection range 3 each time. There is a disadvantage that accurate editing operation cannot be expected because there is no denying that there is a possibility that the user may mistakenly specify the file name. This problem is noticeable in an electronic device having a small display screen such as a portable information terminal or a portable telephone.
[0005]
Therefore, the problem to be solved by the present invention is that even when the selection range is too large to fit on one editing screen, the entire selection range can be seen through, so that the selection range is erroneously set. An object of the present invention is to provide an electronic device, a display control method, a program, and a recording medium that can perform an accurate editing operation without fear of designation.
[0006]
[Means for Solving the Problems]
The present invention provides a display unit for displaying document data, a designation unit for designating an editing range of the document data including a range displayed on the display unit, and an editing range designated by the designation unit is displayed on the display unit. Determining means for determining whether or not all can be displayed; and when the determining means determines that all of the specified editing ranges cannot be displayed, the specified editing ranges are all displayed on the display means. Display control means for reducing and displaying the image.
According to the present invention, it is determined whether or not the entire edit range of the document data can be displayed on the display means. In the case of a negative determination, the edit range is reduced and displayed so as to be entirely displayed on the display means.
Therefore, even when the editing range is too wide to be displayed on the display means, the entire editing range can be seen through the reduced display, and there is no possibility that the editing range is specified by mistake. Accurate editing operations can be expected.
Alternatively, the present invention provides a display unit for displaying document data, a designation unit for designating an editing range of the document data including a range displayed on the display unit over a plurality of pages, and an editing unit designated by the designation unit. Display control means for controlling a plurality of pages including the range to be displayed as thumbnails.
According to the present invention, a plurality of pages including the editing range specified by the specifying unit are displayed as thumbnails. Therefore, even if the editing range is too large to fit on one page, the entire editing range is displayed by thumbnail display. Therefore, there is no possibility that the selection range is erroneously specified, and an accurate editing operation can be expected.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings, taking an example of application to a personal computer having a word processor function. In the following description, the specification or examples of various details and examples of numerical values, character strings, and other symbols are merely reference for clarifying the idea of the present invention, and all or some of them Obviously, the idea of the invention is not limited. In addition, well-known techniques, well-known procedures, well-known architectures, and well-known circuit configurations (hereinafter, “known matters”) will not be described in detail, but this is also for the purpose of simplifying the description, It does not intentionally exclude all or some of the matters. Such a well-known matter can be known to those skilled in the art at the time of filing the present invention, and is naturally included in the following description.
[0008]
FIG. 1 is an external view of a personal computer 10 and a conceptual diagram of a hardware configuration thereof. The personal computer 10 is a general-purpose product having a known architecture (D operating system / V architecture, etc.). In the figure, a so-called desktop personal computer 10 in which a display unit 12, a keyboard 13, a pointing device (a mouse 14 in the figure), a printer 15, and the like are connected to the main body unit 11 is illustrated, but is not limited thereto. Not done. It may be a notebook type or a tower type.
[0009]
It should be noted that the names of the personal computers 10 (“personal computer” and “personal computer”) have no special meaning and are merely general names. Other names such as “workstation”, “office computer (office computer)”, “minicomputer (minicomputer)”, or “information processing device” may be used.
[0010]
The personal computer 10 has a slight difference in configuration in terms of scale, stability and the like for each model, but there is no great difference in a basic configuration (architecture) as a so-called “computer”. Reference numeral 10 denotes a main body 11 in which a CPU 16, a RAM 17, a disk controller 18, a disk device 19, a display controller 20, a keyboard controller 21, a printer port 22, a main bus 23, a bus interface 24, an internal bus 25, and the like are provided. A display device 12, a keyboard 13, a mouse 14, a printer 15, and the like are externally mounted on the main body 11.
[0011]
The personal computer 10 loads an operating system and various application programs (hereinafter, these are collectively referred to as “software resources”) installed in the disk device 19 in advance into the RAM 17 and executes the programs on the CPU 16, thereby enabling the CPU 16 and the like. Various processing functions are realized by the organic combination of the above hardware resources and the above software resources.
[0012]
One of the processing functions is a function as a word processor executed in the personal computer 10 (hereinafter, referred to as “word processor function”). Hereinafter, the word processor function will be described in detail.
[0013]
FIG. 2A is a diagram illustrating a simplified hierarchical model of hardware resources and software resources of the personal computer 10. This hierarchical model 20 simulates an operating system I (Open Systems Interconnection; referred to as open system interconnection) reference model, in which an operating system layer 32 and an application layer 33 are provided on a hardware resource layer 31. Are laminated.
[0014]
The hardware resource layer 31 includes a hardware resource 34 (the configuration of FIG. 1B) such as the CPU 16, and is indirectly transmitted from the application layer 33 via an operating system 35 included in an operating system layer 32 thereon. Enable use. The application layer 33 includes at least a predetermined application program 36 (for example, "Word (R)" of Microsoft Corporation) which is a main part of the "word processor function", and these software resources (the operating system 35 and the application program 36). ) And the hardware resources 34 implement the “word processor function” in the present embodiment.
[0015]
FIG. 2B is a conceptual diagram of the “word processor function” in the present embodiment. In this figure, the word processor 38 is realized by an organic connection between the above-mentioned software resources (the operating system 35 and the application program 36) and the hardware resources 34, as described above. Conceptually, it can be divided into the input unit 39, the character processing unit 40, the selection processing unit 41, and the display control unit 42.
[0016]
The input unit 39 takes in operator operation commands, that is, key commands from the keyboard 13 and the mouse 14, and outputs those commands to the character processing unit 40 and the selection processing unit 41. Commands from the keyboard 13 include “A” to “Z”, “a” to “z”, “A” to “n”, and “A” to “Z” if the keyboard 13 has JIS layout keys of the full standard. Character commands such as "a" to "n", numeric commands "0" to "1", symbol commands such as "-", "/", "*", "+", "=",. Control commands such as “ESC”, “TAB”, “SHIFT”, “CTRL”, “ENTER”, “ROLLUP” (next page), “ROLLDOWN” (previous page), etc., and “f1” to “f1” Function commands such as f10 ″ are included. The key commands from the mouse 14 include a mouse cursor coordinate command, a left button operation command, a right button operation command, and other commands (for example, a wheel operation command).
[0017]
The character processing unit 40 performs “kana-kanji conversion” or “romanization conversion” of the input character string based on a command (mainly a character command or a numeric command) from the input unit 39, generates a Japanese sentence, and generates a generation result. Is output to the display control unit 42. Further, the selection processing unit 41 performs a process of specifying a character string selection range on a word processing screen, which will be described later, based on a command (mainly, a mouse cursor coordinate command, a mouse cursor coordinate command, and a left button operation command) from the input unit 39. Then, the processing result is output to the display control unit 42.
[0018]
The display control unit 42 generates a word processing screen based on the information output from the character string processing unit 40 and the selection processing unit 41, and outputs the screen to the display device 12 for display.
[0019]
FIG. 3 is a diagram showing a word processing screen. In this figure, a display area 12a of the display device 12 has, for example, a resolution of XGA (extended Graphics Array) (1024 × 768 dots), and is displayed when the personal computer 10 executes the word processor 38. The word processing screen 50 is displayed in the area 12a.
[0020]
The basic layout of the word processor screen 50 is Windows (R), which is one of the representative operating systems, with a title bar 51 at the upper end and a command control area 52 under the title bar 51 as shown in the figure. Further, a client area 53 as an operator operation area is arranged below the client area 53.
[0021]
Although the use of the client area 53 differs depending on the function of the application, the illustrated client area 53 is a child object of the word processing screen 50, and thus is used as an edit screen 54 for a character string, a graphic, or the like. The operator inputs desired character strings and figures on the editing screen 54 to create document data such as sentences, and executes various editing operations such as deleting, copying, and moving the character strings and figures.
[0022]
Next, an example of an editing operation according to the present embodiment will be described.
FIG. 4 is a diagram showing the example. The editing screen 54 displays a sentence 55 that has already been input (in the illustrated example, this is an example of a novel "Botchan" by Soseki Natsume, but the content of this sentence has no special meaning).
[0023]
Now, it is assumed that a desired range of the sentence 55 is selected, and some editing operation is performed on the character string in the selected range. In this case, the operator operates the mouse 14 to move the cursor to the first character string of the selected range (for example, “na” of “why such darkness”), presses the left button of the mouse 14, and presses the left button. The cursor is moved while holding down (drag operation), and when the last character string of the selection range is reached (for example, “ra” of “from relatives”), the drag operation is released.
[0024]
As a result, all the character strings included in the selection range 56 are highlighted, and it is clearly indicated that any operation can be currently performed on the character strings in the range.
[0025]
The point of the word processor function in the present embodiment is that when the selection range 56 exceeds one editing screen 54, the sentence 55 is reduced and displayed so that the entire selection range 56 fits on one editing screen 54. is there. That is, in the above example, since the selection range 56 is composed of two parts, a part 56a that fits on the edit screen 54 and a part 56b that does not fit (protrude) on the edit screen 54, it is necessary to display the protruding part 56b. It is necessary to perform scrolling or page switching, and with the scrolling or page switching, the start of the selection range 56 is removed from the editing screen 54, so that the entire selection range 56 can be seen through. There is a disadvantage of disappearing. For this reason, the operator must remember the start position of the selection range each time, and is unkind. There was a problem that accuracy could not be ensured.
[0026]
Therefore, in order to solve the above-mentioned inconvenience, in the word processor function of the present embodiment, when the selection range is widened beyond one editing screen 54, as shown in the lower part of FIG. By displaying the sentence 57, the entire selection range 58 (the range from the start to the end of the selection) can be displayed on one editing screen 54. According to this, since the entire selection range 58 can be checked at once, it is not necessary to remember the selection start position each time, and the accuracy of the editing operation can be improved.
[0027]
Note that the above-described reduction processing may be applied to a so-called page layout screen (a screen that displays an object such as a graphic image or the like and that holds a print output layout almost accurately).
[0028]
FIG. 5 is a diagram showing a page layout screen after reduction processing. On the edit screen 54, a page layout mode sentence 59 reduced to such an extent that the whole of the selection range 60 can be seen is displayed.
[0029]
Note that the above-described reduction processing may be applied to a screen having a page separator.
FIG. 6 is a diagram showing an example of the screen. The difference from FIG. 4 is that a page break symbol 63 (horizontal line in the figure) is inserted in the sentence 61 after reduction. In this example, the selection range 62 extends before and after the page delimiter 63, and the operator recognizes that the selection range 62 has been specified across pages by checking the page delimiter 63. can do.
[0030]
Further, when the selection range extends over pages, reduced display may be performed in page units.
FIG. 7 is a diagram showing an example of the screen. On the edit screen 54, two reduced pages 64 and 65 are displayed separately on the left and right, and a selection range 66a and 66b is designated across these pages 64 and 65. According to this, the difference between pages can be grasped intuitively.
[0031]
FIG. 8 is a flowchart showing main processing (particularly, selection range specifying processing) of the application program 36 according to the present embodiment. In this flowchart, first, selection information (selection start position and end position of a sentence or the like) is extracted (step S11), and then it is determined whether or not the selection range fits on one editing screen (step S12). If it fits, the resolution of the character is checked (step S14) while keeping the display size of the character as it is, while if the selection range does not fit on one edit screen, calculation is performed in a direction to reduce the display size of the character (step S14). S13) The determination in step S12 is repeated again. Therefore, by the processing of steps S12 and S13, "if the selection range is wide enough to not fit on one editing screen, the display of the editing screen is reduced so that the selection range fits on one editing screen". be able to.
[0032]
The “resolution” in step S14 is the resolution of the display device 12. For example, the resolutions are VGA (Video Graphics Array: 640 × 480 dots), SVGA (Super Video Graphics Array: 800 × 600 dots), XGA (extended Graphics Array: 1024 × 768 dots), and SXGA (Super12 × X12 × X12: X12 × X12) 1024 dots), but these have higher resolution in the order of VGA → SVGA → XGA → SXGA. The higher the resolution, the sharper the finer characters can be displayed.
[0033]
Here, when the display device 12 is of an external type (replaceable type), the display device 12 of a high resolution (for example, XGA or SXGA) is not always attached, and in some cases, a low resolution (VGA or the like) is used. ) May be attached. In this case, if the character size is too small, it becomes inappropriate for the display device 12 (characters are crushed and cannot be read), and some countermeasures are required.
[0034]
Therefore, in the present embodiment, the resolution of the display device 12 is checked in step S14, and the lower limit character size (for convenience, 8P (point)) that can be displayed at that resolution is calculated in step S13. If the display size is smaller, the display size of the character is fixed to its lower limit (8P) (step S15), and then the next display process (step S16) is executed.
[0035]
On the other hand, if the calculated display size is equal to or larger than the readable lower limit size, it is next determined whether or not the edit screen should be displayed in a reduced size (step S17). If the display is to be reduced, the display size is changed (changed in the reduction direction) in step S13, and the display size is adapted to the resolution of the display device 12 in step S14. This is the case when it is determined. In such a case, first, the reduction direction is extracted (step S18), and it is determined whether or not the extraction result is the direction of the previous page (step S19). If it is the direction of the previous page, the start position of the selection range is set to the bottom line of the editing screen (step S20), or if it is not the direction of the previous page, the start position of the selection range is set to the top line of the editing screen. Is set (step S21), display processing (step S16) is executed.
[0036]
As described above, according to the above-described flowchart, it is determined whether or not the selection range fits on one editing screen (step S12). If not, the display size of a character string or the like is changed to a smaller size. (Step S13) After the editing screen is reconstructed using the display size (Steps S18 to S21), the display processing (Step S16) is performed. Therefore, the editing screen is reduced to the editing screen 54 as shown in FIG. The text 57 can be displayed, and the entire selection range 58 (the range from the start to the end of the selection) can be displayed on one editing screen 54. Therefore, the entire selection range 58 can be checked at a time, and it is not necessary to remember the selection start position, so that the accuracy of the editing operation can be improved.
[0037]
Further, based on the resolution of the display device 12, the lower limit of the reduction rate (minimum character size in the above example) is set, and measures are taken so as not to perform reduction below that. It is possible to avoid inconveniences (such as collapse of characters) when using the low-resolution display device 12.
[0038]
Note that, in the above embodiment, when the selection range does not fit on one editing screen, the display size of characters in the editing screen is reduced, and the entire sentence is reduced to fit on one editing screen. I have. That is, the inconvenience is avoided by changing the display mode of the editing screen itself, but the idea of the present invention is not limited to this.
[0039]
Hereinafter, another preferred embodiment of the present invention will be described.
FIG. 9 is a diagram illustrating a word processing screen 50 according to the present embodiment. In the client area 53 of the word processing screen 50, an editing screen 54 similar to the above-described embodiment is displayed, and further, a “layout display frame 70” unique to the present embodiment is displayed. The layout display frame 70 may have, for example, a shape imitating a “balloon” as shown in the figure, or may open and display another screen (such as a pop-up screen).
[0040]
FIG. 10A is a diagram showing a normal use state of the layout display frame 70. In this case, the layout display frame 70 has an edit page (second page in the figure) currently being edited on the edit screen 54. Are displayed.
[0041]
FIG. 10B is a diagram illustrating a special use state of the layout display frame 70. “Special” means that it is detected that the selection range does not fit on one editing screen. In this case, in the layout frame 70, a plurality of (three in the figure, from the second page to the fourth page) thumbnail images 74 to 76 are displayed. The highlighted portions (filled portions in the figure) displayed in the thumbnail images 74 to 76 represent the current selection range. Therefore, since the start position and the end position of the selected range can be intuitively grasped only by glance at the thumbnail images 74 to 76, the same effect as in the above-described embodiment can be obtained. Note that the emphasized portion displayed in the thumbnail images 74 to 76 is not limited to the illustrated fill. For example, the color may be changed or underlined. In short, the difference from the surroundings may be clarified so as to be as prominent as possible.
[0042]
In the above-described embodiment, the highlighted portions indicating the selection range are displayed in the thumbnail images 74 to 76. However, when the thumbnail images 74 to 76 are considerably small, the context of the selection range in the sentence cannot be grasped, and it may be difficult to specify the position. As a measure against this, the following may be performed.
[0043]
FIG. 11A shows one example of the countermeasure. This example is common to the above example (FIG. 10B) in that a plurality of thumbnail images 78 to 80 are displayed in the layout frame 70, and has a specific attribute character string (for example, having a heading attribute) in the text. Character strings; hereinafter, "headwords") are highlighted. The highlighting of the character string can be, for example, enlargement of the character size, bold character, color tone change, underlining, italic, or a combination thereof.
[0044]
According to this, the specific character string (entry word or the like) in the text of the thumbnail images 78 to 80 is highlighted, so that it is easy to grasp the positional relationship of the selection range in the text, and the above-described inconvenience can be solved.
[0045]
FIG. 11B shows another example of countermeasures. This example is common to the above example (FIG. 10B) in that a plurality of thumbnail images 83 to 90 are displayed in the layout frame 70, and has a specific attribute character string (for example, having a heading attribute) in the text. Character strings; hereinafter referred to as "entry words") are replaced with other character strings 91a to 91e (numerical values of "1" to "5" in the figure; hereinafter, referred to as "tag characters" for convenience). .
[0046]
According to this, for example, even when the thumbnail images 83 to 90 are considerably small and small characters are difficult to read, those characters (particularly headwords and the like) are converted into tag characters such as numerical values that are relatively easy to read. Since the replacement is displayed, the positional relationship of the selection range in the text can be easily grasped by referring to the tag character, and the above-mentioned inconvenience can be solved.
[0047]
FIG. 12 is a flowchart corresponding to FIG. 11A and FIG. 11B, showing the main part processing of the application program 36 in the present embodiment. In this flowchart, first, the number of pages of a document (document data) to be edited is extracted (step S31), and selection range information is extracted (step S32). The selection range information is information on a start position and an end position of the selection range. Specifically, the selection range starts from what number of column on what page, and on what number of line on what page. This is information (page information, line information, and digit information) as to whether or not the selection range is visually terminated.
[0048]
Next, based on the number of pages and the selection range information, it is determined whether to display in page units or in text units (step S33). When displaying in text units, display information is created by setting the total number of pages, display start page / line / column, and display end page / line / column (step S37). The display information is created by setting the number of pages in the range, the start page / line / column of the selection range and the end page / line / column of the selection range (step S34). In any case, the headword extraction process (step S35) is performed. After the execution, a display process is executed (step S36).
[0049]
FIG. 13 is a flowchart of the headword search processing (step S35 in FIG. 12).
In this flowchart, after setting the search range (search start page and search end page) (step S41), while sequentially looping through all the lines in the search range, the attributes of each line are extracted (step S43), However, for example, the determination as to whether or not the entry is a headword (step S44) is repeated until the last line of the search range is reached, and when the last line is exceeded (when the determination result in step S42 is "YES"), The process ends.
[0050]
When a headword is detected in an arbitrary line (when the determination result in step S44 is “YES”), the reduction ratio of the thumbnail image is checked (step S45), and it is possible to determine even if the headword is displayed as it is. Is determined. If it is possible to determine (display OK), the headword is stored in the RAM 17 as a highlighted character string (step S46). If it is not possible to determine (display NG), an arbitrary word is used instead of the headword. Is stored in the RAM 17 as the highlighted character string (step S47), and the process returns to the loop.
[0051]
FIG. 14 is a diagram illustrating a storage example of the RAM 17. The highlighted character string table 96 has a header field 96a, a line number field 96b, a byte number field 96c, a line attribute field 96d, a format field 95e, and a character string field 96f. Stores information. For example, the type to be edited ("text" in the figure) is stored in the header field 96a, the line number of the highlighted character string is stored in the line number field 96b, and the number of bytes of the highlighted character string (byte number field 96c) is stored in the byte number field 96c. Character attribute information), the line attribute of the highlighted character string is stored in the line attribute field 96d, the format of the highlighted character string (font type, number of points, etc.) is stored in the format field 96e, and the character string field 96f is stored. The character strings of the highlighted character strings (for example, “chapter 1”, “section 1”, “section 2”, “section 3”,...) Are stored.
[0052]
According to this flowchart, for example, a headword (“Chapter 1”, “Section 1”, “Section 2”, “Section 3”,...) Included in the search range is detected. Then, the headword can be highlighted in the thumbnail image, or an arbitrary tag character string (such as a numerical value) can be highlighted in the thumbnail image instead of the headword.
[0053]
Thus, the display result of FIG. 11A or FIG. 11B can be obtained.
[0054]
Therefore, according to each of the above embodiments, even in the case of a wide selection range over a plurality of pages, the text to be edited can be reduced and the selection range can be displayed on one editing screen without any trouble, or Can be displayed in the thumbnail image, and the entirety from the start to the end of the selected range can be visually checked. As a result, unlike the related art, it is not necessary to remember the start position of the selection range, so that it is possible to prevent the setting error of the selection range due to a storage error and to perform an accurate editing operation. Effects can be obtained.
[0055]
Further, since the size of the text to be edited is set in accordance with the resolution of the display device 12 being used, it is possible to avoid excessive reduction such that characters are crushed and become unreadable.
[0056]
When a thumbnail image is used, a specific character string (for example, a headword) in the thumbnail image is extracted and the specific character string is highlighted, so that the context of the selection range in the thumbnail image can be grasped. It is easy to perform and the position can be grasped intuitively.
[0057]
In addition, since a specific character string in a thumbnail image can be replaced with a more legible tag character string (such as a numerical value), a small-sized thumbnail image can be used, and many thumbnail images can be used. Can be lined up.
[0058]
The main functions of the present embodiment are functionally realized by an organic combination of hardware resources including a microcomputer and software resources such as an operating system and various application programs. In addition, since the general-purpose operating system can be used, it can be said that essential items indispensable for the present invention are substantially collected in the application program 36 (see FIG. 2A). . Accordingly, the present invention provides various recording media (such as magnetic disks, optical disks, hard disks, and semiconductor storage devices) that store all or a main part of the application program 36 (not only those that are on a distribution channel, but also (Including those that provide only recorded contents).
[0059]
【The invention's effect】
According to the present invention, it is determined whether or not the entire edit range of the document data can be displayed on the display means. In the case of a negative determination, the edit range is reduced and displayed so as to be entirely displayed on the display means. . Therefore, even when the editing range is too wide to be displayed on the display means, the entire editing range can be seen through the reduced display, and there is no possibility that the editing range is specified by mistake. Accurate editing operations can be expected.
Alternatively, since a plurality of pages including the editing range specified by the specifying means are displayed as thumbnails, even if the editing range is too large to fit on one page, the entire editing range can be seen through thumbnail display. Therefore, there is no possibility that the selection range is erroneously specified, and an accurate editing operation can be expected.
