<Overview of conventional calibration processing>
FIG. 1 is a diagram showing an outline of a conventional general calibration process. As shown in FIG. 1, first, a document is sent from a print orderer or editor (hereinafter referred to as an orderer / editor) to a print shop. The printing shop creates a typesetting for printing, and sends a printed matter printed for proofreading (this is called proof printing, especially the first one is called the first school) to the orderer / editor.

The orderer / editor writes the correction contents in the correction portion of the proof. In FIG. 1, the case where a red pen is used is assumed, and red calibration is shown. The orderer / editor sends the deficit proof to the print shop. The printing office corrects the typesetting based on the sent deficit proof and performs proof printing again.

  Then, the printing office collates the content of the proof with the content of the deficit proof, confirms that there is no typographical error, and submits the proof again to the orderer / editor. Such red letter proofing and proof printing are collated by the number of times of proofing between the printing shop side and the orderer / editor side. In a printed matter that requires accuracy, the number of calibrations may be more than ten times. The document processing system supports such a proofreading process.

<System configuration>
FIG. 2 is a configuration diagram of a document processing system according to an embodiment of the present invention. The document processing system includes a display device 1 that displays document data, a display control unit 3 that controls the display device 1, a cursor position detection unit 4 that is connected to the display control unit 3, and a cursor position detection unit 4. It has an input device 5 that is connected and detects a user operation, and a comparison processing unit 2 that cooperates with the display control unit 3 to compare document data.

  The display device 1 displays document data to be proofread, menus for proofreading operations, icons, messages, and the like. The display device 1 is, for example, a CRT, a liquid crystal display, a plasma display panel (PDP), an electroluminescence (EL) panel, a field emission display (FED), or the like.

  The display control unit 3, the cursor position detection unit 4, and the comparison processing unit 2 are realized by a program or firmware executed by a CPU (not shown). Among these, the display control unit 3 includes divided display means 31 and difference highlighting display means 32.

  The division display means 31 divides the screen of the display device 1 and displays two document data in each division area. That is, the divided display unit 31 is configured to compare the first document data to be compared (for example, document data before correction) and the second document data (for example, a document in which the first document data is corrected) according to the user's specification. Data). At this time, the divided display unit 31 displays the portion of the document data before correction and the portion of the document data after correction that follows the portion in two divided areas.

  Then, by freely moving the boundary between the two divided areas by operating the input device 5, the corresponding portions of the document data before and after the correction are alternately displayed, thereby supporting the proofreading.

  The difference highlighting display means 32 highlights the changed portions of the two document data and displays them on the screen of the display device 1. The emphasis is, for example, changing the background color of a portion where a difference is detected between two document data (difference portion of document data before and after correction).

  The cursor position detection unit 4 detects a user operation on the input device 5 and transmits it to the display control unit 3. The input device 5 generates an input signal in response to a user operation and passes it to the cursor position detection unit 4. The input device 5 is, for example, a keyboard or a pointing device such as a mouse, a touch panel, or a trackball.

  The comparison processing unit 2 includes a drawing data comparison unit 21 and compares two document data in a state displayed on the screen. In the present embodiment, the document data includes data such as characters, ruled lines, or graphics, and is data to be displayed or printed, which is also simply referred to as a document or data.

<Screen example>
FIG. 3 shows an example of screen division. In FIG. 3, the calibration screen 11 of the display device 1 is displayed. The calibration screen 11 has a menu column 14 in which various menus are displayed. Further, the calibration screen 11 is divided into left and right regions by a dividing line 12 in the vertical direction.

  Then, in the area on the left side of the dividing line 12, the portion included in the area of the first document data, for example, the document data before correction is displayed. Further, in the area on the right side of the dividing line 12, the portion included in the area of the second document data, for example, the corrected document data is displayed.

  Therefore, in this case, the right part of the dividing line 12 of the document data before correction is not displayed. Further, the left part of the dividing line 12 of the corrected document data is not displayed. Hereinafter, it is assumed here that the first document data is the document data before correction, and the second document data is the document data after correction.

  Further, the calibration screen 11 is characterized in that the first document data and the second document data are displayed after matching the corresponding positions of the first document data and the second document data. Here, the corresponding position refers to the origin of the first document data and the second document data (display reference point, for example, the start position of the document). In this way, the document processing system displays the document data to be proofread by pasting the original data and the corrected data at the boundary of the dividing line 12 after matching the origins. Such a display makes it easier to compare and compare document data before and after correction.

  Furthermore, the vertical dividing line 12 can be moved left and right by operating the input device 5. For example, on the calibration screen 11 in the upper part of FIG. 3, a dividing line 12 exists at the position of the character “C” in the character string “Research Center”. Further, since there is no change in the character “S” itself, there is no difference between the left and right of the dividing line 12.

  Now, when the dividing line 12 is moved leftward, for example, dragged with a mouse or the like, a display as shown in the middle of FIG. 3 is obtained. On the left side of the proofreading screen 11, the character string “engineer research” of the document data before correction is displayed up to the left half of the characters “Study”. On the other hand, on the right side of the proofreading screen 11, the character string “Fixing center (temporary)” of the corrected document data is displayed from the right half of the “Fixed” character.

  The two document data are synthesized at the positions of the left half of the character “Stu” and the right half of the character “Osamu”. As a result, the user recognizes that the character string “research center” has been changed to the character string “training center”.

  When the user drags the vertical dividing line 12 further to the left, as shown in the lower part of FIG. 3, the dividing line 12 moves to the character “ken”, and it is recognized that this character was not corrected. Is done. In the above description, the first document data in the area on the left side of the dividing line 12 is the document data before correction, and the second document data in the area on the right side of the dividing line 12 is the document data after correction. However, the reverse may be possible.

  Note that the characters “Stu” (left half) and “Osamu” (right half) are highlighted and highlighted in black and white to clearly show that there is a difference between the two document data at this location. It is.

  FIG. 4 shows an example of division direction switching. The configuration of the upper calibration screen 11 in FIG. 4 is the same as that in FIG. 3, and is divided by vertical dividing lines 12.

Now, when the user drags the vertical dividing line 12 in the vertical direction by the input device 5, FIG.
As in the middle calibration screen 11, the vertical dividing line 12 disappears and the horizontal dividing line 13 is displayed.

  In the calibration screen 11 in the middle of FIG. 4, a horizontal dividing line 13 is displayed above the character string “Wear technician training center”. Then, in the area above the dividing line 13, the portion of the area of the first document data, for example, the document data before correction is displayed. Further, in the area below the dividing line 13, the portion of the area of the second document data, for example, the corrected document data is displayed.

  Therefore, in this case, the lower part of the dividing line 13 of the first document data is not displayed. Further, the upper part of the dividing line 13 of the second document data is not displayed. Also in this case, the origin of the first document data and the origin of the second document data are matched.

  In this way, the calibration screen 11 in FIG. 4 displays the first document data and the second document data by combining the origins of the two document data and combining them with the dividing lines. For example, the proof screen 11 displays the document data to be proofread by pasting the data before and after the correction at the boundary of the dividing line 13.

  When the user drags the horizontal division 13 downward on the calibration screen 11 in the middle stage of FIG. 4, the division line 13 moves as in the lower stage. On the lower calibration screen 11, the character string in the upper part of the dividing line 13 called “ware engineer research center” and the character string in the lower part of the dividing line 13 called “ware engineer training center” are on the dividing line. Are combined and displayed. When the user drags the horizontal dividing line 13 in the horizontal direction, the display changes to the vertical dividing line 12 as shown in the upper row.

  FIG. 5 is a display example for comparing and displaying the difference in allocation position. On the calibration screen 11 in the upper part of FIG. 5, corresponding portions of the two document data are displayed in combination at the position of the dividing line 13 in the horizontal direction. When the user drags the horizontal dividing line 13 downward, the horizontal dividing line 13 moves to the character string portion of “Software Engineer Lab” as in the middle calibration screen 11.

  In the middle calibration screen 11, there is a half-size space at the beginning of the character string “Software Engineer Lab” in the first document data (above the dividing line 13). On the other hand, such a space does not exist at the position of the second document data. Therefore, the two document data are displayed in a shifted state above and below the dividing line 13.

  The reason why the character string “software” is highlighted and reversed in black and white is to clearly show that there is a difference between the two document data at this location.

<Screen split display processing>
FIG. 6 is a diagram showing an outline of screen division. In FIG. 6, a mouse is used as the input device 5, and an operation for comparing document data before and after proofreading is shown. That is, the calibration screen 11 is divided into two regions on the left and right by a vertical dividing line 12.

  In FIG. 6, for example, the left part of the dividing line when the document A before proofreading is displayed on the proofreading screen 11 and the right part of the dividing line when the corresponding part of the document B after proofreading is displayed on the proofreading screen 11. Are combined and displayed at the position of the dividing line 12. The user confirms the difference between the documents existing on the left and right of the dividing line 12 by moving the vertical dividing line 12 to the left and right using the input device 5 such as a mouse.

  FIG. 7 is a diagram showing an outline of the method of overlapping division display. FIG. 7 shows the relationship between the display of the calibration screen 11 of the display device 1 and the drawing development data on a memory (not shown).

  The display control means 3 shown in FIG. 2 holds the drawing development data A for displaying the document A in the area 33 on the memory, and holds the drawing development data B for displaying the document B in the area 34 on the memory. The drawing development data A for displaying the document A is also simply referred to as data A. The same applies to data B.

  The drawing development data A and B are bitmap data for displaying the document files A and B on the screen. The divided display means 31 of the display control means 3 delivers this bitmap data to the API (Application Interface) of the OS (Operating System) and displays it on the display device 1.

  At this time, the divided display unit 31 reads the drawing development data A corresponding to the left side portion of the dividing line 12 in the area 33 holding the bitmap, and delivers it to the API. Further, the divided display means 31 reads the drawing development data B corresponding to the right side portion of the dividing line 12 in the area 34 holding the bitmap and delivers it to the API. Thereby, the corresponding portions of the two documents are displayed on the proofreading screen 11.

  For example, when the user scrolls the document A on the calibration screen 11, the split display unit 31 simultaneously scrolls the drawing development data A and the drawing development data B and delivers them to the API.

  Further, for example, when the user drags the dividing line 12 to the left and right, the divided display unit 31 draws the drawing development data A corresponding to the left part of the divided line 12 after the dragging from the drawing development data A and the drawing development data of the right part. B is extracted and delivered to the API. The same processing is performed when the calibration screen 11 is divided by the horizontal dividing line 13.

  FIG. 8 is an image diagram in which the origin is shifted and displayed. In this document processing system, the user can designate a shift when displaying two documents in combination, that is, a shift amount between the two documents. This shift amount can be defined by the shift amount between the origin of document A (for example, the display position on the calibration screen 11 at the head portion of the document) and the origin of document B.

  In FIG. 8, the drawing development data A held in the area 33 on the memory and the drawing development data B held in the area 34 are overlapped by moving the origin by one line of text data, and combined and displayed on the calibration screen 11. ing.

  Then, in the upper part of the dividing line 13 of the proofreading screen 11, the part of the document A that ends with the line of the character string “Aiueo” is displayed, and in the lower part of the dividing line 13, the characters “Aiueo” are displayed. The portion of document B starting from the column row is displayed. Thereby, the line of the character string “Aiueo” is displayed both above and below the dividing line 13. FIG. 9 shows such a display result.

  Note that the shift amount is not necessarily limited to one line, and may be one or more lines. Moreover, you may make it designate the unit of less than one line, for example, the number of points of a character, and the number of pixels by a unit. Then, when the two drawing development data are overlaid, the shift amount may be calculated in units of the number of pixels.

  FIG. 10 is a diagram showing a typesetting coordinate system. As shown in FIG. 10, the document processing system defines a typesetting coordinate system with the x axis (size x) in the right direction and the y axis (size y) in the down direction, with the upper left point of the screen of the display device 1 as the origin. To do.

  Each character data has a rectangular existence area, and the upper left point of the existence area is an allocation position. For example, when the character “A” is arranged at the position (x, y) on the typesetting, the upper left point of the character “A” is assigned to the position (x, y) in the typesetting coordinate system.

  FIG. 11 is an image diagram of division direction switching. In FIG. 11, a mouse is used as the input device 5 and an operation of switching the division direction is shown. Now, in the upper part of FIG. 11, the calibration screen 11 is divided into two regions on the left and right by a vertical dividing line 12. Corresponding portions of document A and document B are displayed in the left and right areas.

  In this state, when the user moves the vertical dividing line 12 up and down with the input device 5 such as a mouse, the calibration screen 11 is divided vertically by the horizontal dividing line 13 as shown in the lower part of FIG. Is displayed. Then, corresponding portions of document A and document B are displayed in the upper and lower areas.

  FIG. 12 is a diagram showing the moving direction and switching range of the mouse pointer. FIG. 12 shows two angular ranges for the vertical dividing line 12. The first is a region in an angular range that is parallel to or nearly parallel to the dividing line 12. This is called a division direction change instruction range. When the user drags the dividing line in the direction of the angle range with the input device 5 such as a mouse, the vertical dividing line 12 disappears, and the calibration screen 11 is divided by the horizontal dividing 13.

  The second is a region in an angular range excluding the first region. This is called a dividing line movement instruction range. When the user drags the dividing line 12 in the direction of this angle range with the input device 5 such as a mouse, the dividing line 12 follows the drag as it is and moves. Thereby, the display position (composition position) of the document synthesized by the dividing line 12 moves.

  The above is a description of the switching range for the vertical dividing line 12, but the horizontal dividing line 13 is obtained by rotating FIG. 12 by 90 degrees.

  FIG. 13 is an example of data in the divided display table. The split display table is a table that defines the configuration of the proof screen 11 and the display specification of document data. The division display table has fields of “start point coordinates”, “end point coordinates”, “division ratio”, “screen division state”, “origin shift amount”, and “difference point display”.

  In the “start point coordinates”, the position (x, y) of the start point coordinates (upper left point of the screen) of the calibration screen 11 is defined in the coordinate system of the display device 1.

  In the “end point coordinates”, the end point coordinates define the position (x, y) of the end point coordinates (the lower right point of the screen) of the calibration screen 11 in the coordinate system of the display device 1.

The “division ratio” defines a ratio when the calibration screen 11 is divided into two by a dividing line. In this document processing system, values of both of the two areas are set as the division ratio. In addition, in the designation of the division ratio, a value higher than the screen resolution is required, and a value smaller than twice the screen resolution has less error. Therefore, in the document processing system of this embodiment, the division ratio is specified with an accuracy of 1/10000.
“Screen division state” indicates the division state of the calibration screen 11. In this field, left / right or top / bottom information is set.
The “origin shift amount” is a shift amount when the origins of two typesetting areas are shifted and compared.

“Difference display” is mode information indicating whether to color or shade a difference, and o
Either n / off is set. When the “difference display” field is on, the difference is displayed by being colored or shaded.

<Drawing data comparison process>
FIG. 14 is an image diagram of a comparative example of drawing data. The drawing data comparison process is realized by comparing a drawing data expansion command (hereinafter referred to as a drawing order) for expanding a document into a bitmap with two comparison target documents.

  For example, let us consider a case where the content of the document A is “aiueka ruled line” and the content of the document B is “ruled line”. This document processing system generates a drawing order for each component when displaying a document on the proofreading screen 11, for example, characters such as “A” and “I” and ruled lines, and expands them into a bitmap through the application interface of the OS. .

  The drawing order for characters is shown in the lower left part of FIG. The drawing orders for characters are “material types such as characters, ruled lines, figures, etc.”, “plate layout (the typesetting area is also referred to as a printing plate), material allocation position (x, y) with the top left as the origin”, “character code”, Each element includes “character size”, “typeface code”, and “decoration information such as rotation and color”.

  “Material type of character, ruled line, figure, etc.” designates whether the drawing order is a drawing order for a character, ruled line, or figure. For example, “Moji” is set as a drawing order for a character. Also, “Keisen” is set as the drawing order for the ruled line. In the present embodiment, such data elements to be drawn are referred to as materials.

  In the “material assignment position (x, y) with the origin at the upper left of the printing plate”, a character assignment position is designated. Here, the printing plate refers to a region of typesetting. Therefore, the coordinates of the allocation position shown in FIG. 10 are set as the allocation position (x, y).

  The “character code” is a code indicating the type of the character. The “character size” is the size of the character, for example, the number of points. The “typeface code” is information indicating a typeface. “Rotation, color and other decoration information” is decoration information for characters such as character rotation, coloring, background color, and shading.

  On the other hand, the drawing order for the ruled line is shown at the lower right of FIG. The drawing orders for the ruled lines are “material type such as character, ruled line, figure, etc.”, “coordinates of the starting point of the ruled line with the origin at the upper left of the printing plate (x, y)”, “end coordinates of the ruled line with the upper left of the printing plate as the origin (x, y) "," ruled line type code "," ruled line width ", and" other modification information ".

  Although not shown in the drawing, the drawing order for the figure is “material type such as character, ruled line, figure, etc.”, “position of figure (x, y) with the upper left of the printing plate as the origin”, “figure code”, “figure width” ”,“ Graphic height ”, and“ decoration information such as rotation, color, pattern, etc. ”.

  The drawing data comparison unit 21 (see FIG. 2) receives the drawing orders for the two documents generated by the divided display unit 31, and compares the components of each drawing order. In this comparison, the drawing orders of the comparison target document A and document B are compared round-robin.

  In that case, the drawing data comparison means 21 first compares the drawing order for the document B with the drawing order for the document A as a reference. That is, the drawing data comparison unit 21 selects drawing orders one by one in order from the top of the document A, and searches the drawing order corresponding to the drawing order from the drawing order for the document B.

  For example, with respect to the first drawing order for the document A (for the character “A”) and the drawing order for the document B (for the character “A”), “material type such as character, ruled line, figure, etc.”, “plate (typesetting) (Also referred to as plate area) Material allocation position with upper left as origin (x, y) ”,“ character code ”,“ character size ”,“ typeface code ”,“ decoration information such as rotation and color ” Compare The drawing data comparison unit 21 determines that the first drawing order (for the character “A”) matches when all of these elements match.

  Next, the drawing data comparison unit 21 compares the next drawing order of the document A (for the character “I”) with the drawing order of the document B whose correspondence is not yet specified.

  In this way, after all drawing orders of document A are compared with the drawing order of document B, there is no corresponding drawing order for which the correspondence is not determined (shown as “none” in FIG. 14). It is determined.

  Next, the drawing data comparison unit 21 compares the drawing order for the document A with the drawing order for the document A on the basis of the drawing order for the document B. The procedure is the same as in the case where the document A is used as a reference.

  The drawing data comparison unit 21 stores such comparison results in a comparison result table. FIG. 15 is a data example of the comparison result table. FIG. 15 shows a comparison result table 1 and a comparison result table 2. The comparison result table 1 is a result of searching the document B with the document A as a reference. The comparison result table 2 is a result of comparing the document A with the document B as a reference.

  Each row of the comparison result table 1 is a comparison result corresponding to each drawing order of the document A. Each row of the comparison result has fields for a material type, an assigned coordinate, a coloring start / end point coordinate, and a difference flag.

  As described with reference to FIG. 14, the material type is a code representing the type of material such as characters, ruled lines, and figures. The allocation coordinates are coordinates for arranging the material (see FIG. 10). The coloring start point / end point coordinates are a pair of vertex coordinates at a diagonal position indicating a rectangular area when coloring is performed for each material (character, ruled line, or figure).

  For example, in the case of a character, since it has a rectangular area as shown in FIG. 10, the coloring start point / end point may be made to coincide with the coordinates of the rectangular area of the character. However, in the case of a ruled line, there is data that does not have a rectangular area and holds only the line width and length of the ruled line. With such data, the ruled lines disappear when coloring, especially black and white reversal.

  Therefore, a slightly larger rectangular area including the ruled line (in this embodiment, an area larger by 2 points) is held as the coloring start point and end point. By reversing black and white in this rectangular area, a ruled line is displayed in a black rectangular area and does not disappear.

  The difference flag is a flag indicating whether or not the material (character or the like) is present in the data of the comparison partner (data B in the comparison result table). For example, the comparison result table 1 in FIG. 15 indicates that the portion corresponding to “ka” in “A” to “ka” of data A and the ruled line is different from data B.

  FIG. 16 shows a display rule for differences between two documents. The document processing system classifies and displays differences between two documents in three cases. Here, the document displayed on the calibration screen 11 of the display device 1 is referred to as a comparison source document. A document that is compared with the comparison source is referred to as a comparison destination document.

  Case 1 is a display when the document exists in the comparison source document and the comparison destination document has no material. This corresponds to the case where there is no material in the document before correction (null), or when a document is added and the documents before and after correction are compared and displayed after adding the material. In this case, materials such as characters, ruled lines, and figures of the comparison source document are displayed in reverse on a black background.

  Case 2 is a case where there is no material in the comparison source document or there is a material in the comparison destination when there is a space. This corresponds to the case where the document before and after the correction is deleted after a part of the material of the document before the correction is compared and displayed. In this case, the corresponding area of the comparison source document is displayed in light blue.

  Case 3 is a case where Case 1 and Case 2 overlap. Case 1 and case 2 overlap when the material before correction, for example, when a character is replaced with another character, or when the position of the character before correction is shifted, the document before and after the correction is compared. This is the case when displayed. In such a region, the background is filled with a color obtained by mixing the colors of Case 1 and Case 2, for example, dark blue, and the material is displayed in light blue.

<Example>
FIG. 17 shows an example of comparison processing. 18 to 20 show a procedure for displaying the comparison result by superimposing data A and data B on the calibration screen 11.
In the example of FIG. 17, as a result of the formatting of the data A, the character string “Aoi” and the character “ka” are separated by two characters. In addition, as a result of the formatting of the data B, a character string “Uo?” Is displayed in a portion corresponding to the portion of the data A indicated as “ぅ”.

  As a result, in the comparison result table A based on the data A, the difference flags of the characters “A” to “ぅ” among the characters “A” to “KA” which are the materials are set to be different.

  Further, in the comparison result table B based on the data B, the difference between the characters “U”, “E”, “O”, “KA” among the characters “U”, “E”, “TAO”, “KA” is the difference. The flag is set to be different.

  FIG. 18 is a display example 1 as a result of the comparison process, and shows a state in which only a display corresponding to case 1 is displayed (a state in which no display corresponding to case 2 is displayed). In this case, in the comparison result table A, the difference flags of the characters “a”, “i”, and “ぅ” are set to “present”. Therefore, the characters “A”, “I” and “ぅ” in the display area of the data A on the calibration screen 11 are displayed in black and white reversed.

  FIG. 19 is a result display example 2 of the comparison process, and shows a state in which only a display corresponding to case 2 is displayed (a state in which no display corresponding to case 1 is displayed). As shown in FIG. 19, the portion of the character string “ぅ ka” of the data A currently being displayed corresponds to the characters “U”, “E”, “O”, and “KA” in the comparison target data B.

When data A is searched with reference to data B, there is a difference in the comparison result table B except for the portion “ka”. Therefore, “ぅ” displayed in the area of data A
Of the “ka” part, the part excluding “ka” is displayed in light blue with the background filled.

FIG. 20 is a display example 3 of the comparison processing result, which is a display combining the display of FIG. 18 and the display of FIG. As described with reference to FIG. 18, the comparison target material does not exist in the “A” and “I” portions of the data A. That is, there is no material in the data B before correction, and the case where the data before and after correction when the material is added at the time of correction is compared and displayed. In this case, the “a” and “i” portions are displayed with the background black and black and white inverted.

  Further, in the portion between “と” and “ka”, there is no material in data A, and there is a material in data B. That is, this corresponds to the case where the material before correction is deleted. In this case, this portion is filled with light blue (in FIG. 20, light hatching).

  For the “に つ い て” portion of data A, “u” exists in the corresponding portion of data B. Therefore, this portion corresponds to the case where “U” in the data B before correction is replaced with “ぅ”. This portion is displayed in dark blue (in FIG. 20, dark hatching).

  As described above, the result of the comparison process may be displayed not on the screen area divided by the dividing line 12 or 13 on the calibration screen 11 but on a normal screen without division.

  FIG. 21 shows an example in which the comparison results of data A and data B shown in FIGS. As shown in FIG. 21, the typesetting result of data A is stored in an area 33 on a memory (not shown). Further, the area 34 stores the typesetting result of the data B.

  As shown in the upper part of FIG. 21, data A is displayed in the area above the horizontal dividing line 13 on the calibration screen 11 as in FIG. Now, when the dividing line 13 is dragged upward by the input device 5, the display area of the data A becomes smaller and the display area of the data B appears (lower part of FIG. 21). In this area, a comparison result with data A based on data B is displayed.

  That is, there is no material of data B in the portion corresponding to “A” and “I” of data A. For this reason, it is painted in light blue (in FIG. 21, light hatching). In addition, for the “u” part, “ぅ” exists in the corresponding part of the data A. For this reason, this area is dark blue and the background is filled. Further, there is no material in the portion of data A corresponding to “E” and “TAO” of data B. For this reason, the background is black and is reversed black and white.

  Further, in the “ka” portion, the same material exists in the comparison source data B and the comparison destination data A, and there is no difference. For this reason, “ka” is displayed in a normal display.

  FIG. 22 shows the details of the operation when displaying the comparison result in the split screen display (the operation in the display of FIG. 21). FIG. 22 shows that the screen changes as shown in the screens 11A to 11D by the user operation. However, in FIG. 22 (and FIG. 23), hatching is shown instead of black and white inversion.

  On the screen 11A, a horizontal dividing line 13 is present at the bottom of the screen 11A. For this reason, on most of the screen 11A, the result when compared with the data B on the basis of the data A is displayed in color (similar to the display in the upper part of FIG. 21).

  On the other hand, on the screen 11D, the dividing line 13 is dragged to the upper part of the screen 11D. Therefore, most of the screen 11D displays the result when compared with the data A with the data B as a reference (similar to the lower display in FIG. 21).

  The screen 11B and the screen 11C display a state in which the position of the dividing line 13 is moved from the position of the screen 11A to the position of the screen 11D by a drag operation by the input device 5. For example, as the screens 11B and 11C progress, the characters “Ai” disappear. In addition, the character “ぅ” becomes a composite character with the character “u”, and further becomes a pure “u” character. In addition, the character “Eo” appears at the position where there was no material.

  FIG. 23 shows a coloring display example in which the origin is shifted. That is, in FIG. 21 and FIG. 22, the origin shift amount is not set for data A and data B above and below the dividing line 13. On the other hand, FIG. 23 shows a display when data B is shifted by one line with respect to data A.

  Now, for example, suppose that the character string of “Aioka” in data A is rewritten to “Uooka”. Then, before rewriting and after rewriting are displayed side by side above and below the dividing line 13. However, as described above, such a shift amount is not limited to one line.

<Comparison exclusion process>
The document processing system according to the present embodiment excludes a portion of the document data that is not output in the screen display or print result of the formatted result from the comparison target. Such parts are mainly the following character symbols.
-Blank characters such as full-width spaces and half-width spaces.
-Control symbols such as line feeds.
-A part where nothing is assigned (null part).

  In addition, the document processing system can customize the non-comparison target by setting in the comparison exclusion table what is excluded from the comparison target as described above.

  FIG. 24 is a data example of the comparison exclusion table. In each row of the comparison exclusion table, a material to be excluded from the comparison target, that is, an element on the typesetting is designated. Each row of the comparison exclusion table has fields of material classification and material code.

  The material type is the name of the material excluded from the comparison target, that is, the element name on the typesetting. The material code is a code of the material. Here, the material to be excluded from the comparison target is specified, but instead, the material to be compared may be set in the table.

  FIG. 25 is a comparative example of a document including characters that are not compared. In this example, data A including a character string “Ai ぅ □□” (□ indicates a space) is compared with data B including a character string “□□ Ueo?”. That is, there is a space between “ぅ” and “ka” in the formatting result of data A and the left side of “u” in the formatting result of data B.

  When the space “□” is set in the comparison exclusion table for the data A and B in this way, the comparison results are as shown in FIGS.

<Action>
FIG. 26 is a flowchart showing processing of the document processing system. This process is realized by a program executed by a CPU (not shown) of the document processing system.

  Normally, the document processing system waits for a trigger input from the input device 5 (step 81, but in FIG. 26 and the subsequent steps, step 81 is simply indicated as 81).

  If there is a trigger input, the document processing system determines whether the trigger input is an instruction to compare document data (step 82). If the trigger input is an instruction to compare document data, the document processing system executes document data comparison processing (step 85). Thereafter, the document processing system returns control to step 81.

  On the other hand, if it is determined in step 82 that the trigger input is not a comparison of document data, the document processing system determines whether the trigger input is an operation of a dividing line (12 or 13) (step 83). If the trigger input is a parting line operation, the document processing system executes parting line operation processing (step 86). Thereafter, the document processing system returns control to step 81.

  If it is determined in step 83 that the trigger input is not a dividing line operation, the document processing system determines whether or not termination has been instructed (step 84). When the end is instructed, the document processing system ends the process.

  On the other hand, if the end is not instructed in the determination in step 84, the document processing system returns the control to step 81.

  FIG. 27 is a flowchart showing details of the document data comparison process (step 85 in FIG. 26). In this process, first, the document processing system reads one page of the two typesetting data A and B (step 91). Next, the document processing system expands the drawing data of the typesetting data (step 92). Here, this development result is referred to as drawing orders A and B.

  Next, the document processing system compares the drawing order B based on the drawing order A (step 93). Then, the document processing system outputs the result to the comparison result table A. Further, the document processing system compares the drawing order A based on the drawing order B (step 94). Further, the document processing system outputs the result to the comparison result table B. Next, the document processing system displays two drawing data (drawing order A and drawing order B) in each area of the calibration screen 11 (step 95).

  Next, the document processing system determines whether or not there is a difference between the two drawing orders A and B (step 96). If there is a difference, the document processing system determines a part set as “difference” in the comparison result tables A and B for the display area of the document A based on the divided display table and the difference display rule table. Colored display is performed (step 97). Similarly, the display area of the document B is colored and displayed (step 98).

  On the other hand, if there is no difference in the determination in step 96, the document processing system determines whether there is a next page (step 99). If there is a next page, the document processing system returns the control to step 91. If there is no next page, the document processing system ends the document data comparison process.

  In this way, the process is repeated until the first page where there is a difference in drawing order is found for the two documents A and B or the comparison of all the drawing orders is completed.

  FIG. 28 is a flowchart showing details of the dividing line operation processing (step 86 in FIG. 26). In this process, the document processing system first determines whether or not an instruction to move the dividing line (12 or 13) has been issued (step 101). When there is an instruction to move the dividing line, the document processing system determines that the movement direction is the area A (here, the area where the first document A is displayed is the area A, and the document A is the comparison target. It is determined whether the area in which the second document B is displayed is referred to as area B) (step 102).

When the moving direction is the direction of the area A, the document processing system executes a process of narrowing the area A and widening the area B (step 103). On the other hand, when the moving direction is not the direction of the area A, the document processing system executes a process of narrowing the area B and widening the area A (step 104). Then, the document processing system ends the process.

  If it is determined in step 101 that the instruction to move the dividing line has not been given, the document processing system determines whether or not there has been an instruction to change the dividing direction (an instruction to operate the dividing line in a direction almost parallel to the dividing line). (Step 105).

  If there is an instruction to change the division direction, the document processing system determines whether the current division is in the horizontal direction (step 107). If the division is in the horizontal direction, the document processing system changes the division direction to the vertical direction (step 107). On the other hand, if the division is in the vertical direction, the document processing system changes the division direction to the horizontal direction (step 108). Then, the document processing system ends the dividing line operation process.

<Effect of embodiment>
As described above, the present document processing system places two documents, for example, the document (A) before correction and the document (B) after correction in the divided areas divided by the dividing line 12 or 13 of the proofreading screen 11. indicate. In that case, the portion included in one divided region when the document before correction is displayed on the proof screen 11 and the portion included in the other divided region when the document after correction is displayed on the proof screen 11 are combined. And display. By moving the dividing line 12 or 13, the user can easily contrast the corrected document and the corrected document near the upper and lower sides or the left and right of the dividing line.

  In the document processing system, the left and right divided screens by the vertical dividing lines 12 and the upper and lower divided screens by the horizontal dividing lines 13 can be easily switched by operating the input device 5.

  Further, the document processing system searches the drawing order (display contents) of document B based on the drawing order (display contents) of document A to detect a difference. Predetermined highlighting, for example, black on the background and black-and-white inversion is displayed at the display location of such document A that is not in the display content.

  Further, the document processing system searches the drawing order (display contents) of document A based on the drawing order (display contents) of document B, detects a difference, and detects the difference in the display contents of document B. A portion of the document A corresponding to the display location of the document B that is not in the display content is displayed with a predetermined highlight, for example, light blue.

  In addition, a predetermined display, for example, a background is filled with a dark blue color and displayed at a location where different materials are displayed for the display content of the document A and the display content of the document B. Therefore, the document processing system clearly highlights the difference between the display contents of the two documents and the mode of the difference. Such a function is particularly effective in proofreading work at the time of creating a printed matter in which document correction and confirmation are repeated.

  In addition, the document processing system can perform divided display as described above and display with emphasis on differences even for data including ruled lines and figures other than characters.

<Modification>
In the above-described embodiment, drawing orders for characters, ruled lines, figures, etc. are defined in a coordinate system with the origin at the upper left of the printing plate (typesetting). However, the implementation of the present invention is not limited to such a coordinate system. For example, a page-by-page coordinate system may be used. Further, the position of the origin may not be the upper left point.

  In the above embodiment, according to the display rules shown in FIG. 16, the display contents of the document A and the document B are different from each other according to the display rule shown in FIG. The method was highlighted. However, the implementation of the present invention is not limited to such display rules. For example, even if a different color is used, or a portion with different display contents is displayed due to hatching, frame enclosing, underline, character string that calls attention, or periodic flashing of those highlighted parts Good.

<Computer-readable recording medium>
A program that causes a computer to realize any of the above functions can be recorded on a computer-readable recording medium. The function can be provided by causing the computer to read and execute the program of the recording medium.

  Here, the computer-readable recording medium refers to a recording medium in which information such as data and programs is accumulated by electrical, magnetic, optical, mechanical, or chemical action and can be read from a computer. Examples of such a recording medium that can be removed from the computer include a floppy (registered trademark) disk, a magneto-optical disk, a CD-ROM, a CD-R / W, a DVD, a DAT, an 8 mm tape, and a memory card. .

  Further, there are a hard disk, a ROM (read only memory), and the like as a recording medium fixed to the computer.

<Data communication signal embodied in carrier wave>
The program can be stored in a hard disk or memory of a computer and distributed to other computers through a communication medium. In this case, the program is transmitted through a communication medium as a data communication signal embodied by a carrier wave. And the said function can be provided to the computer which received the distribution.

  Here, the communication medium may be a wired communication medium, for example, metal cables including a coaxial cable and a twisted pair cable, an optical communication cable, or the like, or a wireless communication medium, for example, satellite communication or terrestrial radio communication.

  The carrier wave is an electromagnetic wave or light for modulating the data communication signal. However, the carrier wave may be a DC signal. In this case, the data communication signal has a baseband waveform without a carrier wave. Therefore, the data communication signal embodied in the carrier wave may be either a modulated broadband signal or an unmodulated baseband signal (corresponding to a case where a DC signal having a voltage of 0 is used as a carrier wave).
