Description

  The present invention provides an information processing apparatus and a display for controlling display of the image data corresponding to the display area on a display apparatus, with the entire read image data as a logical area, and a predetermined area in the logical area as a display area. The present invention relates to a control method, a program, and a recording medium.

  In the finance / life insurance industry, etc., a form is read by an image reading device such as a scanner, image data is acquired, and a specific area in the image data is designated and OCR (Optical Character Reader) processing is performed. Extracting character data.

  Here, since the accuracy of the OCR process depends on the designation of the specific area, the user needs to finely adjust and designate the specific area. In addition, when it is desired to check the form key or the like described in the form, it is necessary to check the description contents in the specified specific area.

  However, if the specific area specified for the entire area (= logical area) of the image data is small, the specific area is not displayed in the display area (= physical area) unless a part of the logical area is enlarged and displayed. It is not possible to make fine adjustments and to specify, and it is also impossible to confirm the description in the specific area.

  For this reason, the user must operate the scroll bar of the window or specify enlargement / reduction in order to specify the specific area by finely adjusting it or to check the description in the specific area. It is cumbersome and cumbersome.

  Japanese Patent Application Laid-Open No. 7-220109 (Patent Document 1) discloses a technique capable of quickly displaying desired data in a physical area while omitting the operation of a scroll bar.

Japanese Patent Laid-Open No. 2001-184049 (Patent Document 2) displays one or a plurality of objects in a logical area so as to fit in a physical area without repeating the enlargement / reduction / scrolling of the window. Techniques that enable this are disclosed.
JP-A-7-220109 JP 2001-184049 A

  However, the technique described in Patent Document 1 stores the mark specified coordinates and the upper left coordinate information of the display area (= physical screen) at that time in a coordinate management table in association with the mark name. When a name is called, if the coordinates designated for marking are not on the physical screen, a technique for changing the display area and displaying the coordinates designated for marking at the center of the physical screen is disclosed. Therefore, even if the technique of Patent Document 1 is used to display an area that is enlarged and confirmed in the area as in the above-described OCR area, the area is displayed each time the enlargement process for confirmation is performed. Often disappears from the display screen, and each time the user needs to perform a complicated operation of specifying and calling the area with a mark name, etc. I could not.

  In addition, the technique described in Patent Document 2 displays a figure in a logical area in a physical area, so that area coordinates on the logical area of the figure are registered in advance, and a figure to be displayed is designated. Can be applied to display the entire specific area in the physical area because the technology to expand the physical area so that the specified figure enters the physical area, but every time you specify the specific area, The display area itself is changed to the size of the specified specific area. As a result, each time a specific area is specified, the display magnification of the specific area is changed, and there is no uniformity in the figure size and character size in the specific area, which not only deteriorates the appearance but also uses it. This makes it difficult to compare the image size and the character size between a plurality of areas, and makes it very difficult to use.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to display the entire read image data as a logical area and a predetermined area within the logical area as a display area.

When there is not, the display area in the logical area is moved so that a part of the specified area is displayed on the physical screen without enlarging or reducing the display area. Uniformity can be maintained, the selected area can be easily confirmed, and even when the process of enlarging and confirming the description in the area as in the OCR area, the selected area is also processed after the enlargement process. Can be displayed on a physical screen, and an information processing apparatus, a display control method, a program, and a recording medium that can easily perform an area enlargement confirmation operation are provided.

  The present invention is an information processing apparatus that uses the entire read image data as a logical area, a predetermined area in the logical area as a display area, and controls display of the image data corresponding to the display area on a display device. A storage means for storing one or a plurality of rectangular data indicating coordinate values of a rectangular area in the logical area; an acquisition means for acquiring a display area in the logical area displayed on the display device; Moving means for controlling movement of the display area acquired by the acquiring means so as to include a rectangular area in the logical area corresponding to any of the rectangular data to be moved, and the moving means moved by the moving means And display control means for controlling display of the image data and the rectangular data corresponding to a display area on the display device.

  In the present invention, there is provided display magnification change instruction means for instructing to change the display magnification of the image data corresponding to the display area displayed on the display device, and the acquisition means is a display magnification by the display magnification change instruction means. The display area after changing the display magnification is acquired in response to the change instruction.

  According to the present invention, the read image data as a whole is a logical area, a predetermined area in the logical area is a display area, and the image data corresponding to the display area is displayed on the display device. The display area in the logical area displayed on the display device is acquired and selected from one or a plurality of rectangular data stored in the storage means as coordinate values of the rectangular area in the logical area Since the acquired display area is controlled so as to include the rectangular area in the logical area corresponding to the rectangular data, even if the selected area is changed, a constant display magnification is displayed on the physical screen (physical area). The rectangle corresponding to the selected area can be displayed with, and when the selected area does not fit in the physical screen, the selected area can be displayed without enlarging or reducing the display area. To move the display area of the logical region so as to be displayed on the physical screen of the parts, it is possible to maintain the integrity of such as a figure or character size of the selected area, it is possible to easily confirm the specified area.

  Further, even when processing such as an OCR region that is enlarged and finely adjusted to specify or check the description in the region is performed, the selected region can be displayed on the physical screen even after the enlargement processing. This makes it possible to specify an area and to perform an operation for confirming the enlargement of the area.

In this case, the execution result in the server 102 is transmitted to the user terminal 101 as a client and displayed on the display 211.

  Hereinafter, an example of display processing in the information processing apparatus of the present invention will be described with reference to FIGS.

  FIG. 3 is a flowchart showing an example of a first control processing procedure in the information processing apparatus of the present invention. The CPU 201 of the user terminal 101 shown in FIG. 2 loads a program stored in the external storage device 204 into the RAM 202. This corresponds to the display processing of the first embodiment realized by executing the above. S301 to S309 indicate each step.

  As shown in FIG. 3, in step S301, the CPU 201 reads image data from an external storage device 204 (server 102, scanner 105, or multifunction machine 103). Thereafter, the CPU 201 handles the entire image data as a logical area 400 as shown in FIG. In the present embodiment, as shown by 401 in FIG. 4, there are a plurality of frames, and the image data of a form that can be entered with characters and the like is read in each frame.

  FIG. 4 is a schematic diagram for explaining a logical area in the information processing apparatus of the present invention.

  As shown in FIG. 4, when the size of the image data 401 is W × H, the CPU 201 uses the upper left vertex of the image data 401 as the origin (0, 0) and the coordinates of the lower right vertex of the image data 401 are (W, The image data 401 is managed in the coordinate system (X, Y) of the logical area 400 that becomes H).

  The description returns to the flowchart of FIG.

  Next, in step S302, the CPU 201 reads the OCR area data (created in advance) of the image data read in step S301 from the external storage device 204 or the like. This OCR area data designates a rectangular area to be subjected to OCR processing on the image data, and the rectangular area in the logical area 400 described above is represented by coordinate values (rectangular upper left coordinates, rectangular lower right coordinates). Coordinates) = ((X1, Y1), (X2, Y2)). The OCR area data is created in advance corresponding to the image data, and is stored in the external storage device 204 in association with the image data.

  Although not shown in the flowchart of FIG. 3, the OCR area data corresponding to the image data read in step S <b> 301 is not stored in the external storage device 204 as in the case where the image data is first read. In this case, the image data read in step S301 is displayed on the physical screen 500 (FIG. 5: physical area such as a window), and the user who uses the pointing device 207 or the like for the image data display on the physical screen 500 The OCR area is designated by the above operation, and the designated rectangular area on the physical screen 500 is converted into coordinates on the logical area 400 and stored in the external storage device 204. Further, the CPU 201 may recognize the frame line on the image data and create the OCR area data.

  In step S303, the CPU 201 displays the image data read in step S301 and the OCR area data read in step S302 on the physical screen 500 (a physical area such as a window) on the display 211. A display example of the image data and the OCR area data is shown in FIG.

  In this process, the CPU 201 displays image data corresponding to all or part of the logical area 400 on a physical screen (window or the like) 500 on the display 211. In the example shown in FIG. 5, the entire logical area 400 is the display area of the physical screen 500, and the CPU 201 obtains image data corresponding to the display area of the physical screen 500 from the coordinates on the logical area 400 on the physical screen 500. It is converted into coordinates and displayed on the physical screen 500. Further, in this process, the CPU 201 converts each OCR area data (logical area 400 coordinate data) read in step S302 from the coordinates on the logical area 400 to the coordinates on the physical screen 500, respectively. Display processing.

  FIG. 5 is a schematic diagram showing a display example of image data displayed on the physical screen on the display 211 shown in FIG. 2 and OCR area data created on the image data.

  As shown in FIG. 5, the image data 401 is displayed on a physical screen 500 such as a window on the display 211. Reference numeral 402 denotes a plurality of OCR area data displayed on the physical screen 500. As a result, the user can refer to the image data displayed on the physical screen 500 on the display 211 and click and select a certain OCR area using the pointing device 207 or the like.

  Reference numeral 501 denotes an enlarge button, and 502 denotes a reduce button. By instructing (clicking) the enlarge button 501 (or the reduce button 502) using the pointing device 207 or the like, the image data 401 can be enlarged (reduced). .

  The description returns to the flowchart of FIG.

  Next, in step S304, the CPU 201 determines whether or not the OCR area data 402 displayed in step S303 has been selected by the keyboard 206, the pointing device 207, or the like shown in FIG. FIG. 6 shows how the OCR area data is selected.

  FIG. 6 is a schematic diagram showing how the OCR area data displayed on the physical screen 500 of the display 211 shown in FIG. 2 is selected. In FIG. 6, reference numeral 503 denotes the selected OCR area data. .

  Here, the user selects a large (small) OCR area on the physical screen 500 of the display 211 in order to confirm the characters and areas described in the OCR area data 503 selected in step S304. It is possible to instruct enlargement (reduction) to be displayed.

  If the CPU 201 determines in step S304 that the OCR area data 402 has been selected, the CPU 201 proceeds to step S305 to determine an enlargement (reduction) instruction, while selecting the OCR area data 402. If it is determined that there is no data, the process proceeds to step S309.

  In step S305, the CPU 201 determines whether an enlargement (or reduction) instruction has been given to the OCR area data selected in step S304. Note that this enlargement (or reduction) instruction indicates whether the enlargement button 501 (or reduction button 502) shown in FIG. 5 displayed on the display 211 is instructed by the keyboard 206 or the pointing device 207 shown in FIG. Judging.

  In step S305, when the CPU 201 determines that there is an enlargement instruction (or reduction instruction) for the OCR area data specified in step S304, the process proceeds to step S306, while an enlargement instruction (or reduction instruction) is issued. If it is determined that there is not, the process proceeds to step S309.

  In step S306, the CPU 201 obtains (acquires) a display area of the image data after the enlargement (reduction) process. A specific example of the display area calculation process will be described with reference to FIG.

  FIG. 7 is a diagram for explaining a display area calculation method in response to a display magnification change instruction (enlargement instruction or reduction instruction) of image data 401 displayed on the physical screen 500 of the display 211 shown in FIG.

  In FIG. 7, reference numeral 701 denotes a display area on the logical coordinate 400 of the image data displayed on the physical screen before the enlargement (reduction) process. Reference numeral 702 denotes a display area on the logical coordinates 400 of image data displayed on the physical screen after the enlargement (reduction) process.

  Assuming that the display magnification after the enlargement (reduction) process is A% and the upper left coordinates of the display area 701 before the enlargement (reduction) process are (X, Y), the rectangular coordinates ((x1) of the display area 702 after the enlargement (reduction) process , Y1), (x2, y2)) are calculated as follows.

x1 = X
y1 = Y
x2 = x1 + W × 100 ÷ A
y2 = y1 + H × 100 ÷ A
Note that the display magnification A% after the enlargement (reduction) processing may be calculated by increasing (decreasing) the current display magnification at a predetermined ratio for each enlargement (reduction) processing instruction. The user may be configured to input or select with the keyboard 206 and the pointing device 207. With the calculation method as described above, the CPU 201 can acquire the display area after the magnification change.

  Hereinafter, the processing returns to the flowchart of FIG.

  Next, in step S307, the CPU 201 fits (includes) the OCR area selected by the user in step S304 within the display area (if it does not fit in the display area, fits the upper left). A process of moving the display area obtained in step S306 (that is, not changing the size of the display area) is performed. This process will be described in detail later with reference to FIG.

  Next, in step S308, the CPU 201 redisplays the image data 401 and each OCR area data 402 on the physical screen 500 in the display area calculated in step S306 and moved in step S307. Therefore, when the size of the display area calculated in step S306 and moved in step S307 is smaller (larger) than the previous display area, the image data and OCR areas displayed on the physical screen are It will be enlarged (reduced). FIG. 8 shows how the image data and the OCR area data are redisplayed.

  FIG. 8 is a schematic diagram showing image data and OCR area data re-displayed on the physical screen 500 of the display 211 shown in FIG.

  In FIG. 8, reference numeral 703 denotes the OCR area data selected in step S304 of FIG. 3 and is displayed so as to fit within the physical screen 500.

  Finally, in step S309, the CPU 201 determines whether or not an end instruction has been given by an end menu (not shown) on the display 211 using the keyboard 206 and the pointing device 207 shown in FIG. If it is determined, the process returns to step S304.

  On the other hand, if the CPU 201 determines in step S309 that an end instruction has been given, the process ends.

  FIG. 9 is a flowchart showing an example of a second control processing procedure in the information processing apparatus of the present invention, and corresponds to the processing in step S307 in FIG. Note that the processing of this flowchart is realized by the CPU 201 of the user terminal 101 shown in FIG. 2 loading a program stored in the external storage device 204 into the RAM 202 and executing it. S801 to S812 indicate each step.

  Here, the upper left coordinates of the selected OCR area data are (X1, Y1), the lower right coordinates are (X2, Y2), and the upper left coordinates of the display area obtained in step S306 are (X3, Y3). ), The lower right coordinates are (X4, Y4), the upper left coordinates of the moved display area are (X5, Y5), and the lower right coordinates are (X6, Y6).

  First, the initial value of (X5, Y5) is set to (X3, Y3), the initial value of (X6, Y6) is set to (X4, Y4), and in step S801, the CPU 201 selects the OCR selected in step S304. It is determined whether the left coordinate (upper left X coordinate) of the area data is within the display area obtained in step S306. If it is determined that the area data is within the display area, the process proceeds to step S803. On the other hand, if it is determined that the image does not fall within the display area, the process proceeds to step S802.

  In step S802, the CPU 201 moves the range of the display area so that the left coordinate of the selected OCR area data falls within the display area. That is, X5 and X6 are changed like “X5 = X1” and “X6 = X3-X1”. Then, the process proceeds to step S803.

  Next, in step S803, the CPU 201 determines whether or not the upper coordinate (upper left Y coordinate) of the selected OCR region data is within the display region, and determines that it is within the display region. If so, the process proceeds to step S805. On the other hand, if it is determined that the image does not fall within the display area, the process proceeds to step S804.

  In step S804, the CPU 201 moves the range of the display area so that the upper coordinates of the selected OCR area data are within the display area. That is, Y5 and Y6 are changed like “Y5 = Y1” and “Y6 = Y3−Y1”. Then, the process proceeds to step S805.

  In step S805, the CPU 201 determines whether or not the right coordinate (lower right X coordinate) of the selected OCR region data is within the display region. In step S807, the process proceeds to step S807. On the other hand, if it is determined that the image does not fall within the display area, the process proceeds to step S806.

  In step S806, the CPU 201 moves the range of the display area so that the right coordinate of the selected OCR area data falls within the display area. That is, X5 and X6 are changed to “X5 = X3 + (X2−X4)” and “X6 = X2”. Then, the process proceeds to step S807.

  Next, in step S807, the CPU 201 determines whether or not the lower coordinate (lower right Y coordinate) of the selected OCR area data is within the display area, and if it is within the display area. If it is determined, the process proceeds to step S809. On the other hand, if it is determined that it is not within the display area, the process proceeds to step S808.

  In step S808, the CPU 201 moves the range of the display area so that the lower coordinate of the selected OCR area data falls within the display area. That is, Y5 and Y6 are changed to “Y5 = Y3 + (Y2−Y4)” and “Y6 = Y2”. Then, the process proceeds to step S809.

  In step S809, the CPU 201 determines whether the left coordinate (upper left X coordinate) of the OCR area data is within the display area. If the CPU 201 determines that the left coordinate is within the display area, step S811 is performed. On the other hand, if it is determined that the image does not fall within the display area, the process proceeds to step S810.

  In step S810, the CPU 201 moves the display area so that the left coordinate of the selected OCR area data falls within the display area. That is, X5 and X6 are changed to “X5 = X1” and “X6 = X1 + (X4−X3)”. Then, the process proceeds to step S811.

  Next, in step S811, the CPU 201 determines whether the upper coordinate (upper left Y coordinate) of the selected OCR region data is within the display region, and determines that it is within the display region. If so, the process is terminated as it is, and if it is determined that it is not within the display area, the process proceeds to step S812.

  In step S812, the CPU 201 moves the range of the display area so that the upper coordinate of the selected OCR area data falls within the display area. That is, Y5 and Y6 are changed like “Y5 = Y1” and “Y6 = Y1 + (Y4−Y3)”. Then, the process is terminated.

  When a plurality of OCR area data are selected in step S303 in FIG. 3, a rectangle including all the selected OCR area data is included in the display area (when the display area does not fit). The display area may be moved in such a manner that the display area is moved in step S307 (so that the upper left is accommodated).

  As described above, in the present embodiment, the entire read image data 401 is a logical area 400, a predetermined area in the logical area is a display area, and the image data corresponding to the display area is displayed on the display 211. In the user terminal 100 that controls display on the physical screen 500, the CPU 201 acquires a display area after changing the display magnification in response to an instruction to change the display magnification of the image data 401 corresponding to the physical screen 500 on the display 211. , Including a rectangular area in the logical area 400 corresponding to any rectangular data selected from one or more rectangular data stored in the RAM 202 or the external storage device 204 as coordinate values of the rectangular area in the logical area The acquired display area is controlled so that it is enlarged so that it is enlarged like the area for OCR. Even in the case of performing processing for confirming the description in the inside, it is possible to display the selected region on the physical screen (physical region) even after the enlargement processing, and there is an effect that the region enlargement confirmation operation can be easily performed. .

  As shown in FIG. 9, when it is impossible to include the rectangular area in the acquired display area, the CPU 201 puts only one vertex of the rectangular area in the display area. The display area is moved and controlled.

  Further, as shown in FIG. 9, the CPU 201 moves the display area so that one of the diagonal vertices of the rectangular area enters, and then enters the other vertex of the rectangular area. Control to move the display area.

  Further, the CPU 201 controls the movement of the display area so as to include all the rectangular areas in the logical area corresponding to the plurality of selected rectangular data.

  If the CPU 201 determines in step S1001 that there is OCR area data selection, the CPU 201 proceeds to step S1002, while if it determines that there is no OCR area data selection, the process proceeds to step S1004. Shift processing.

  In step S1002, the CPU 201 acquires the current display area, and performs a process of moving the current display area so that the OCR area data selected in step S1001 is stored in the display area. This process is the same as the process shown in FIG.

  In step S1003, the CPU 201 redisplays the image data and each OCR area data on the physical screen 500 in the display area moved in step S1002. FIG. 13 shows the relationship between the display area before the area is selected and the display area after the area is selected.

  FIG. 13 is a schematic diagram illustrating an example of a relationship between a display area before the area is selected and a display area after the area is selected in the information processing apparatus according to the second embodiment of the present invention.

  As shown in FIG. 13, before the OCR area data 900 is selected by the user, a “display area before the OCR area is selected” 901 is displayed. When the OCR area is selected by the user (Y in step S1001 in FIG. 10), the display area 901 (that is, the partial area on the logical area 400 displayed on the physical screen 500) by the procedure described in FIG. ) Is moved so that the selected OCR area data 900 is contained as indicated by 902, and “display area after the area is selected” is displayed on the physical screen 500. As a result, the selected OCR area data 900 is displayed on the physical screen 500 as indicated by reference numeral 701 in FIG.

  As a result, the user can easily check the character strings and frames in the OCR area and the OCR area itself without performing a complicated operation such as scrolling.

  Specific description will be given below.

  For example, the upper left coordinates of the OCR area data 900 to be selected are (X1 = 480, Y1 = 480), the lower right coordinates are (X2 = 700, Y2 = 520), and before the OCR area data 900 is selected. If the upper left coordinates of the display area 901 are (X3 = 0, Y3 = 0) and the lower right coordinates are (X4 = 500, Y4 = 500), the upper left of the display area 902 after the OCR area data 900 is selected. The coordinates (X5, Y5) and the lower right coordinates (X6, Y6) are calculated and moved as follows. This case corresponds to the case where (X4-X3)> (X2-X1) and (Y4-Y3)> (Y2-Y1), that is, the size of the OCR area data 900 does not exceed the size of the display area 901. It becomes as follows.

X5 = X3 + (X2-X4) = 0 + (700-500) = 200
Y5 = Y3 + (Y2-Y4) = 0 + (520-500) = 20
X6 = X2 = 700
Y6 = Y2 = 520
Further, when the upper left coordinates of the OCR area data 900 to be selected are (X1 = 480, Y1 = 480) and the lower right coordinates are (X2 = 1000, Y2 = 520), the OCR area data 900 is selected. The upper left coordinates (X5, Y5) and the lower right coordinates (X6, Y6) of the display area 902 are calculated and moved as follows. In this case, (X4-X3) <(X2-X1) and (Y4-Y3)> (Y2-Y1), that is, the size of the OCR area data 900 exceeds the size of the display area 901 in the X direction. Corresponding to the case, it is as follows.

X5 = X1 = 480
Y5 = Y3 + (Y2-Y4) = 0 + (520-500) = 20
X6 = X1 + (X4-X3) = 480 + (500-0) = 980
Y6 = Y2 = 520
Further, if the upper left coordinates of the OCR area data 900 to be selected are (X1 = 480, Y1 = 480) and the lower right coordinates are (X2 = 700, Y2 = 1000), the OCR area data 900 is selected. The upper left coordinates (X5, Y5) and the lower right coordinates (X6, Y6) of the display area 902 are calculated and moved as follows. In this case, (X4-X3)> (X2-X1) and (Y4-Y3) <(Y2-Y1), that is, the size of the OCR region data 900 exceeds the size of the display region 901 in the Y direction. Corresponding to the case, it is as follows.

X5 = 480
Y5 = 480
X6 = X1 + (X4-X3) = 480 + (500-0) = 980
Y6 = Y1 + (Y4-Y3) = 480 + (500-0) = 980
Hereinafter, the description returns to the flowchart of FIG.

  Finally, in step S1104, the CPU 201 determines whether or not an end instruction has been given by an end menu (not shown) on the display 211 using the keyboard 206 or the pointing device 207 shown in FIG. If it is determined, the process returns to step S1001.

  On the other hand, if the CPU 201 determines in step S1104 that an end instruction has been given, the process ends.

  When a plurality of OCR area data are selected in step S1001 in FIG. 10, a rectangle including all the selected OCR area data is included in the display area (when the display area does not fit). The display area may be moved in such a manner that the display area is moved in step S1003 (so that the upper left is accommodated).

  Further, the first embodiment and the second embodiment are combined, and in step S305 in FIG. 3, the CPU 201 determines that there has been no instruction to enlarge (or reduce) the OCR area data selected in step S304. In such a case, the processing in steps S1002 and S1003 in FIG. 10 may be performed, and the selected area may be redisplayed within the display area, and the processing in step S309 in FIG. 3 may be performed.

  As described above, in the present embodiment, the entire read image data 401 is the logical area 400, a predetermined area in the logical area is the display area, and the image data corresponding to the display area is displayed on the display 211. In the user terminal 101 that controls display on the physical screen 500, the CPU 201 acquires a display area in the logical area 400 displayed on the physical screen 500 on the display 211, and stores the logical area in the RAM 202 or the external storage device 204. The display area is moved so as to include the rectangular area in the logical area 400 corresponding to any rectangular data selected from one or a plurality of rectangular data stored as coordinate values of the rectangular area in the area. Because it controls, even if the selected area is changed, the specified area is displayed at a constant display magnification on the physical screen (physical area). A rectangle corresponding to can be displayed, and when the specified area does not fit in the physical screen, a part of the specified area is displayed on the physical screen without enlarging or reducing the display area. Thus, since the display area in the logical area is moved, it is possible to maintain the uniformity of the figure and the character size in the designated area, and the designated area can be easily confirmed.

  As shown in FIG. 9, when it is impossible to include the rectangular area in the acquired display area, the CPU 201 puts only one vertex of the rectangular area in the display area. The display area is moved and controlled.

  Further, as shown in FIG. 9, the CPU 201 moves the display area so that one of the diagonal vertices of the rectangular area enters, and then enters the other vertex of the rectangular area. Control to move the display area.

  Further, the CPU 201 controls the movement of the display area so as to include all the rectangular areas in the logical area corresponding to the specified plurality of rectangular data.

  Therefore, a rectangle corresponding to the desired selected area data can be displayed in a certain physical area, and when the selected area does not fit in the physical area, the physical area is not enlarged or reduced. The effect that the uniformity of the character size etc. in the selection area can be maintained by moving the display area in the logical area displayed in the physical area so that a part of the selection area is displayed in the physical area. Play.
