Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a range designation device, a range designation method, and a recording medium that can designate a desired range on a screen of a display device.
[0002]
[Prior art]
  When a rectangular range having a desired size is specified at a desired position on the screen of a display device such as a computer display, it is common to indicate two points that are diagonal to the rectangular range to be specified. In that case, usually, the mouse button is pressed with the tip of the mouse cursor (pointer) in the shape of an arrow (→) at one vertex of the rectangular range to be specified, and the one point is kept pressed. After moving the tip of the mouse cursor to the vertex at the diagonal position (so-called drag operation), the mouse button is released (release). As a result, it is possible to designate a rectangular range whose diagonal positions are the two points at the tip of the mouse cursor when the mouse button is pressed and released.
[0003]
[Problems to be solved by the invention]
  However, when trying to specify a range very precisely by the method as described above, the tip of the mouse cursor needs to be accurately stopped at a desired position, which is increasingly increased as the display resolution is improved. It has become difficult. Therefore, the current situation is that the user cannot perform precise range designation without taking an unreasonable posture such as bringing his face close to the display, and the efficiency of the range designation operation is reduced.
[0004]
  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a range designation device, a range designation method, and a computer-readable recording medium on which a program therefor is recorded, which enables a user to perform an efficient and precise range designation operation. It is.
[0005]
[Means for Solving the Problems]
  In order to achieve the above object, the range specifying device according to claim 1 includes a pointer display control means for displaying a pointer indicating an arbitrary position in a predetermined display area in the display area, and a display in the display area. And an enlarged display control means for enlarging and displaying the vicinity area of the position indicated by the pointer in the loupe area having a predetermined display size in the display area, and representing the range designated by the pointer in the display area Frame line display control means for displaying a frame line in the display area.The enlarged display control means includes a search means for searching for a position in the display area such that the loupe area is within the display area, and a movement for moving the loupe area to a position found by the search means. The frame line display control means prevents the frame line from being displayed when the loupe area overlaps the frame line by moving the loupe area by the moving means.
[0006]
  Claims5The range designation method includes a step of displaying a pointer indicating an arbitrary position in a predetermined display area in the display area, and a vicinity area of the position indicated by the pointer in the display area. A magnified display in a loupe area having a predetermined display size, and a step of displaying a frame line representing the range designated by the pointer in the display area in the display area.A range designation method for searching for a position in the display area such that the loupe area fits in the display area; and moving the loupe area to a position found by the searching step; And a step of preventing the frame line from being displayed when the loupe region overlaps the frame line by moving the loupe region.
[0007]
  Claims9Displaying a pointer indicating an arbitrary position in a predetermined display area in the display area; and a vicinity area of the display area indicated by the pointer in the display area. A step of magnifying and displaying in a loupe area having a display size, and a step of displaying a frame line representing a range designated by the pointer in the display area in the display area.Searching for a position in the display area such that the loupe area fits in the display area; moving the loupe area to a position found by the searching step; and moving the loupe area. Thereby preventing the frame line from being displayed when the loupe area overlaps the frame line;It is a computer-readable recording medium which recorded the program for performing.
[0008]
  Claim 1,5, 9According to the above, when the range is designated with the pointer, the area near the position designated by the pointer is enlarged and displayed in the loupe area. Therefore, the user can efficiently and refer to the enlarged and displayed image in the loupe area. It becomes possible to perform a range specification operation precisely.
[0009]
[0010]
[0011]
[0012]
[0013]
[0014]
[0015]
[0016]
  Furthermore, claims 1, 5, 9According to the above, when a loupe area having a predetermined display size is searched for a position within the display area, the loupe area is moved to a position found by this search, and the loupe area overlaps with the frame line. Since the frame line is not displayed, the enlarged display portion in the loupe area is easy to see without displaying the frame line. In addition, since the display position is determined on the condition that the loupe area may be overlapped with the frame line as long as it is within the display area, the loupe area is displayed as close as possible to the pointer. The range designation operation can be performed more efficiently.
[0017]
  In the present invention, when performing the search, when the frame line is rectangular, around the vertex indicated by the pointer, around the vertex constituting the short side together with the vertex indicated by the pointer The search may be performed in the order around the vertices that form a long side together with the vertices indicated by the pointer, and around the vertices that are diagonally opposite the vertices indicated by the pointer. (Claims2, 6, 10)
[0018]
  Claim2, 6, 10According to the above, when specifying a rectangular range, the search starts from around the vertex indicated by the pointer, and the search is performed in order from the periphery of the vertex closer to this vertex to the periphery of the vertex farther away. The loupe area is displayed at a nearby location, so that the user can perform the range specifying operation more efficiently.
[0019]
  In the present invention, in performing the search, a search may be performed for a plurality of locations around one vertex. (Claims3, 7, 11)
[0020]
  Claim3, 7, 11Since a search is performed for a plurality of locations around one vertex, it is possible to increase the possibility that the loupe area is displayed as close as possible to the pointer.
[0021]
  In the present invention, when the loupe area cannot be displayed at the display size as a result of the search, the loupe area may be reduced to a size smaller than the display size and displayed. (Claims4, 8, 12)
[0022]
  Claim4, 8, 12According to the above, when the loupe area cannot be displayed with the predetermined display size, the loupe area is reduced to a size smaller than the predetermined display size, so the loupe area cannot be displayed even when the display area is small. Almost disappears.
[0023]

[0032]
  Then bookReference exampleA specific configuration of the personal computer 1 which is the range specifying device according to the above will be described with reference to FIG. Figure 2 shows a bookReference example2 is a block diagram of the personal computer of FIG.
[0033]
  BookReference exampleAs shown in FIG. 2, the OS and other software are incorporated in the main body 10 of the personal computer 1, so that the input control unit 22, the determination unit 23, the drawing control unit 24, the print control unit 25, the shape A storage unit 26, a mode storage unit 27, a reference position storage unit 28, and a selection frame storage unit 29 are configured. The drawing control unit 24 includes a frame display control unit 31, a cursor display control unit 32, and an enlarged display control unit 33. The enlarged display control unit 33 includes a search unit 33a and a moving unit 33b. And a storage unit 33c. Each unit in the main body unit 10 is realized by a combination of hardware such as a CPU, RAM, ROM, and hard disk, and software such as an OS.
[0034]
  The input control unit 22 receives an input signal from the keyboard 12 and also receives an input signal from the mouse 13, specifically, a mouse button on the set side of either left or right (this bookReference exampleThen, the depressing and releasing signal of the left button 13a) and the mouse movement signal accompanying the rotation of the mouse ball are received. The determination unit 23 receives data from the input control unit 22, the shape storage unit 26, the mode storage unit 27, the reference position storage unit 28, and the selection frame storage unit 29 and makes various determinations as described later. The drawing control unit 24 receives data from the input control unit 22 and the determination unit 23 and controls the drawing contents on the display 11.
[0035]
  The frame line display control unit 31 of the drawing control unit 24 performs control for drawing a frame line of a predetermined shape (rectangular, circular, etc.) on the display 11 in accordance with the movement of the mouse cursor. The cursor display control unit 32 performs control for moving the mouse cursor on the display 11 in conjunction with the movement of the mouse 13. The magnified display control unit 33 performs control for appropriately displaying the loupe on the display 11. Specifically, the search unit 33a searches for a position that satisfies the above condition, and the moving unit 33b moves the loupe to a position that satisfies the above condition. In addition, the storage unit 33c temporarily stores data necessary for control in the enlarged display control unit 33 such as a search result in the search unit 33a.
[0036]
  The print control unit 25 receives data from the drawing control unit 24 and performs control for printing the data contents of the tape editor using the tape printer 2. The shape storage unit 26 stores whether the shape designated by the user by the input from the keyboard 12 or the mouse 13 is a rectangle, a circle, a curve, or the like. The mode storage unit 27 stores whether the personal computer 1 is in the range designation state or in the range designation state, whether it is the start point designation mode or the end point designation mode. A book that specifies a rectangular rangeReference exampleThen, the position where the left button 13a of the mouse 13 is pressed is set as the starting point of the rectangular range, and the position where the pressed left button 13a is released is set as the end point (diagonal point of the starting point) of the rectangular range. I am doing so.
[0037]
  The reference position storage unit 28 stores the coordinate position of a reference point (two diagonal points in the case of a rectangle and one point on the center and a circle in the case of a circle) of a specified range. The selection frame storage unit 29 stores the coordinate position of the display dot on the selection frame displayed on the display 11 by the range specifying operation.
[0038]
  Then bookReference exampleIn the case where the end point of the rectangular range is set by the example, when the loupe is displayed on the display 11, the two conditions described above (the loupe fits within the display area of the display 11, and the loupe is the selection frame line (rectangular frame The order of searching for a position that satisfies the condition that does not overlap with the line) will be described with reference to FIG. Figure 3 shows the bookReference exampleFIG. 6 is a conceptual diagram for explaining the loupe search order when the end point of a rectangular range is set as described above. Here, as shown in FIG. 3, the start point (D) of the rectangular range is at the upper left corner of the rectangular range, and the tip of the mouse cursor (current point (A)) that is moved to set the end point is the rectangular range. A case in the lower right corner will be described. 3 is a horizontally long rectangle, and the length of the vertical side (CD = AB) is shorter than the length of the horizontal side (AC = BD). That is, the vertical side is a short side and the horizontal side is a long side.
[0039]
  BookReference exampleWhen searching for the end point in FIG. 3, as shown in FIG. 3, around the lower right vertex that is the current point (A), around the upper right vertex (B) that forms a short side together with the current point (A), the current point (A ) Along with the lower left vertex (C) constituting the long side and the upper left vertex (D) on the diagonal of the current point (A) in order, the search unit 33a searches for a position satisfying the above two conditions. Further, around each vertex A, B, C, D, at the four points that are equidistant from each vertex in the lower right, lower left, upper right, and upper left directions, respectively, the lower right point → the lower left point → the upper right point → In the order of the upper left point, it is determined whether or not a loupe area having a predetermined radius around the vertex satisfies the above two conditions. That is, in the case of FIG. 3, the positions satisfying the above two conditions in the order of A1, A2, A3, A4, B1, B2, B3, B4, C1, C2, C3, C4, D1, D2, D3, D4. Is searched by the search unit 33a, and when the position satisfying the above two conditions is found, the subsequent search is stopped, the moving unit 33b moves the loupe to that position, and the loupe is displayed.
[0040]
  Like thisReference exampleThen, since the search is started from the vicinity of the current point where the tip of the mouse cursor is located, and a place far from the current point is searched gradually, a loupe can be displayed as close as possible to the current point. In addition, since the search is performed at four locations around one vertex, for example, even if the lower right point of a vertex does not satisfy the condition, the lower left point may satisfy the condition, and only one location per vertex Compared to the case where the search is performed with, the possibility that the loupe is displayed as close as possible to the current point is increased. In the example of FIG. 3, the start point is the upper left corner and the current point is the lower right corner. However, if the start point is the upper right corner and the current point is the lower left corner, the start point is the lower left corner and the current point is the upper right corner. The same processing is performed when the starting point is the lower right corner and the current point is the upper left corner.
[0041]
  Then bookReference exampleA specific range specifying procedure according to will be described with reference to FIGS. 4 to 11 as an example of specifying a rectangular range. 4A to 4G are diagrams schematically illustrating a positional relationship between the frame line of the rectangular range and the loupe. In addition, FIGS.Reference example5 is a flowchart for explaining a procedure for specifying a range according to FIG.
[0042]
  When specifying a rectangular range, a predetermined operation is performed in advance to activate the enlarged display software, and the keyboard 12 or the mouse 13 is operated to input that the specified range is rectangular. This input data is stored in the shape storage unit 26. The determination unit 23 refers to the shape storage unit 26 and determines that the reference position storage unit 28 stores two reference positions of a rectangular start point and end point. At this time, in step S1 of FIG. 5, the mode storage unit 27 is set to the start point designation mode in the range designation state, and the start point is not designated.
[0043]
  Next, in step S2, the determination unit 23 determines whether the left button 13a of the mouse 13 has been pressed. If it is determined that the left button 13a has been pressed (S2: YES), the process proceeds to step S3. In step S3, the left button pressing process shown in FIG. 6 is performed. In step S31 of FIG. 6, the pressing point of the left button 13a is set as the first reference point (start point), and the position is stored in the reference position storage unit 28. In step S32, after the mode storage unit 27 is set to the end point designation mode, the left button pressing process is terminated.
[0044]
  If it is determined in step S2 that the left button 13a has not been pressed (S2: NO), the process proceeds to step S4. In step S4, the determination unit 23 determines whether the left button 13a has been released. If it is determined that the left button 13a has been released (S4: YES), the process proceeds to step S5. In step S5, the left button release process shown in FIG. 7 is performed. In step S51 of FIG. 7, the determination unit 23 determines whether or not the mode storage unit 27 is in the end point designation mode. If the end point designation mode is not set (S51: NO), the left button release process in FIG. 7 is terminated. If the end point designation mode is set (S51: YES), the process proceeds to step S52.
[0045]
  In step S <b> 52, the determination unit 23 determines whether or not the released position of the left button 13 a is the same position as the position of the start point stored in the reference position storage unit 28. As a result, if it is determined that the position is the same (S52: YES), the left button release process in FIG. 7 is terminated, and if it is determined that the position is different (S52: NO), the drag operation of the mouse 13 is performed. As a result, the process proceeds to step S53. In step S53, the release point of the left button 13a is set as the second reference point (end point), and the position is stored in the reference position storage unit 28. In step S54, the mode storage unit 27 stores the fact that the range has been specified, and then the left button release process is terminated.
[0046]
  If it is determined in step S4 that the left button 13a has not been released (S4: NO), the process proceeds to step S6. In step S6, the determination unit 23 determines whether or not the mouse 13 has moved. If it is determined that the mouse 13 has moved (S6: YES), the process proceeds to step S7. In step S7, the mouse movement process shown in FIG. 8 is performed. In step S <b> 71 of FIG. 8, the determination unit 23 determines whether or not the mode storage unit 27 is in the end point designation mode with reference to the stored contents of the mode storage unit 27. If it is not in the end point designation mode (S71: NO), the start point has not been set yet, so steps S72 to S74 relating to the selection frame described below are skipped and the process proceeds to step S75. On the other hand, if it is in the end point designation mode (S71: YES), the process proceeds to step S72.
[0047]
  In step S 72, the contents of the selection frame stored in the selection frame storage unit 29 are erased by an instruction from the determination unit 23. Next, in step S73, a rectangular frame whose diagonal is the start point and the current mouse cursor tip position is drawn by the frame line display control unit 31 of the drawing control unit 24 and displayed on the display 11, and the mouse 13 is moved. The cursor display control unit 32 changes the position of the mouse cursor on the display 11 according to the direction and distance. In step S74, the position of the rectangular frame is stored in the selection frame storage unit 29.
[0048]
  Then, the process proceeds to step S75, and the loupe display position calculation process shown in FIG. 9 is performed. In step S751 of FIG. 9, the position where the tip of the current mouse cursor is (current point) is set as the first search reference point (search reference point 1) and stored in the storage unit 33c. In step S752, the position of the vertex that forms the short side of the rectangle together with the current point is defined as the second search reference point (search reference point 2) in the rectangle having the start point and the current point as two diagonal points. Set and store in the storage unit 33c. Further, in step S753, the position of the vertex that forms the long side of the rectangle together with the current point is set as the third search reference point (search reference point 3), stored in the storage unit 33c, and finally, in step S754, The position of the starting point at the diagonal of the current point is set as the fourth search reference point (search reference point 4) and stored in the storage unit 33c. In Steps S751 to S754, when the start point is not set, the search reference points 2 to 4 are not set and only the search reference point 1 is set.
[0049]
  In step S755, the parameter N representing the search reference point stored in the storage unit 33c is set to 1, and the process proceeds to step S756. In step S756, a process of searching for a loupe displayable position around the search reference point (FIG. 10) is performed. In step S781 in FIG. 10, a position that is a predetermined distance away from the search reference point specified by the parameter N in the lower right direction (for example, a direction in which a horizontal axis extending rightward from the search reference point is rotated 45 ° clockwise). Is set as a search position in the storage unit 33c.
[0050]
  In step S782, a process for checking whether or not the loupe can be displayed at the search position set in the previous step is performed (FIG. 11). In this process, first, in step S801 in FIG. 11, the search unit 33a determines whether or not the substantially circular loupe drawn to have the predetermined radius with the search position as the center is within the display area of the display 11. The If the loupe fits within the display area of the display 11 (S801: YES), the process proceeds to step S802, and if not (S801: NO), the process proceeds to step S806.
[0051]
  Subsequently, in step S802, it is determined whether or not the mode stored in the mode storage unit 27 is the start point designation mode. When the start point designation mode is set (S802: YES), since the selection frame is not displayed on the display 11, the condition that the loupe does not overlap the selection frame line is unconditional out of the two conditions described above. Therefore, the process proceeds to step S805. In step S805, after the fact that the loupe can be displayed at the search position is stored in the storage unit 33c, the process of checking whether the loupe in FIG. 11 can be displayed is terminated.
[0052]
  If it is determined in step S802 that the start point designation mode is not set (S802: NO), it means that the mode stored in the mode storage unit 27 is the end point designation mode. As a result, a rectangular frame having the start point and the current point as diagonal points is displayed on the display 11. Therefore, in step S803, the substantially circular loupe drawn so as to have a predetermined radius centered on the search position overlaps at least partly with the rectangular area in the selection frame whose diagonal is the current point and the start point. The search unit 33a determines whether or not to do so. If the loupe does not overlap the rectangular area in the selection frame at all (S803: NO), the above two conditions are satisfied, and the process proceeds to step S805. On the other hand, in other cases, that is, when the loupe partially overlaps the rectangular area in the selection frame (the loupe overlaps the rectangular frame line of the selection frame) and the loupe is completely included in the rectangular area in the selection frame. In the case (S803: YES), the process proceeds to step S804.
[0053]
  In step S804, the search unit 33a determines whether the loupe is completely included in the rectangular area in the selection frame or whether it partially overlaps the rectangular area in the selection frame. If the loupe is completely included in the rectangular area in the selection frame (S804: YES), the loupe does not overlap the rectangular frame line of the selection frame, and therefore the above two conditions are satisfied, so step S805. Proceed to On the other hand, when the loupe is not completely included in the rectangular area in the selection frame (S804: NO), the loupe overlaps with the rectangular frame line of the selection frame, so the above two conditions are not satisfied. The process proceeds to step S806. In step S806, after storing in the storage unit 33c that the loupe cannot be displayed at the search position, the process of checking whether the loupe can be displayed is terminated.
[0054]
  After step S805 or step S806 is completed, the process returns to step S783 in FIG. 10, and the search unit 33a determines whether or not a loupe can be displayed at the search position based on the stored contents of the storage unit 33c. If the loupe can be displayed (S783: YES), the process proceeds to step S794, and the storage unit 33c is set to indicate that the loupe can be displayed at the search position of the search reference point.
[0055]
  On the other hand, if display of the loupe is impossible (S783: NO), the process proceeds to step S784, and the horizontal axis extending from the search reference point designated by the parameter N to the lower left direction (for example, the left direction from the search reference point) is counterclockwise. A position separated by a predetermined distance in the direction rotated 45 ° around is set in the storage unit 33c as a search position. Then, the process proceeds to step S785, and similarly to step S782, a process for checking whether or not the loupe set in the previous step can be displayed is performed. Thereafter, the process proceeds to step S786 to determine whether or not a loupe can be displayed at the search position. If the loupe can be displayed (S786: YES), the process proceeds to step S794. If the loupe cannot be displayed (S786: NO), the process proceeds to step S787.
[0056]
  In step S787, a position separated by a predetermined distance in the upper right direction (for example, a direction in which the horizontal axis extending rightward from the search reference point is rotated 45 ° counterclockwise) from the search reference point specified by the parameter N is searched for. Is set in the storage unit 33c. Then, the process proceeds to step S788, and a process for checking whether or not the loupe set in the previous step can be displayed is performed as in step S782. Thereafter, the process proceeds to step S789, and it is determined whether or not a loupe can be displayed at the search position. If the loupe can be displayed (S789: YES), the process proceeds to step S794. If the loupe cannot be displayed (S789: NO), the process proceeds to step S790.
[0057]
  In step S790, a position that is a predetermined distance away from the search reference point specified by the parameter N in the upper left direction (for example, a direction in which a horizontal axis extending leftward from the search reference point is rotated 45 ° clockwise) is set as the search position. Set in the storage unit 33c. Then, the process proceeds to step S791, and a process for checking whether or not the loupe set in the previous step can be displayed is performed as in step S782. Thereafter, the process proceeds to step S792 to determine whether or not a loupe can be displayed at the search position. If the loupe can be displayed (S792: YES), the process proceeds to step S794. If the loupe cannot be displayed (S792: NO), the process proceeds to step S793.
[0058]
  After step S793 or step S794 ends, the process returns to step S757 in FIG. 9 to determine whether or not the loupe can be displayed at the search reference point specified by the parameter N. If the loupe can be displayed (S757: YES), the process proceeds to step S758, the search position of the search reference point set in step S794 is set as the loupe display position, and the loupe can be displayed at the search position. Is stored in the storage unit 33c.
[0059]
  If display of the loupe is impossible (S757: NO), the process proceeds to step S759. In step S759, the parameter N is incremented by 1. In step S760, it is determined whether the parameter N is less than 5.
[0060]
  If the parameter N is less than 5 (S760: YES), the process returns to step S756, and the loupe displayable position search process is performed around the next search reference point as described above. As a result, a search around the next search reference point is performed according to the rule described with reference to FIG. On the other hand, if the parameter N is 5 or more (S760: NO), the process proceeds to step S761. In step S761, the storage unit 33c stores that the loupe cannot be displayed on the display 11 when the mouse cursor is at the current position.
[0061]
  After step S758 or step S761 is completed, the process returns to step S76 in FIG. 8 to determine whether or not the loupe can be displayed in the display area of the display 11 based on the setting content of the storage unit 33c. If the result of the determination is that a loupe can be displayed (S76: YES), the process proceeds to step S77. In step S77, the moving unit 33b moves the substantially circular loupe having a predetermined radius to the position set in step S758, and further displays the loupe at the moved position, and then the mouse movement process is terminated. If the loupe cannot be displayed (S76: NO), the mouse movement process is terminated without displaying the loupe.
[0062]
  Returning to FIG. 5, if it is determined in step S6 that the mouse 13 has not moved (S6: NO), the process proceeds to step S8 without performing the mouse movement process in step S7. In step S8, the determination unit 23 determines whether or not the mode storage unit 27 has instructed the end of range specification. If it is determined that the mode storage unit 27 has not instructed the end of range specification (S8: NO), the process returns to step S2 and the same processing is repeated. On the other hand, if it is determined that the mode storage unit 27 has instructed the end of range specification (S8: YES), the presentReference exampleIf the screen capture is set, the specified range data is supplied to the tape editor. Thereafter, when the user operates the tape editor or when the data in the specified range is supplied to the tape editor, the print control unit 25 is automatically activated and the data in the specified range is printed on the tape. Printed by device 2.
[0063]
  The flow described above will be described by applying a specific example. For example, when a relatively small rectangular area is specified at a position sufficiently away from the display end of the display 11 as shown in FIGS. 4A, 4B, and 4C, the starting point S of the rectangular area should be the first. Since the tip of the mouse cursor 40 is moved to the position, the process proceeds from step S2 to step S7 through step S4 and S6. Since the start point designation mode is set in step S71, the process proceeds to the loupe display position calculation process in step S75, the search reference point 1 is set in step S751, and the loupe displayable position search process in step S756 is performed. In this case, since a loupe can be displayed at the lower right of the search reference point, steps S781, S782 (steps S801, S802, S805 are executed during step S782), steps S783, S794, and step S757. Returning to Step S77, the loupe 44 is displayed in Step S77 after Steps S758 and S76.
[0064]
  After that, by repeatedly passing through the loop of steps S 2 → S 4 → S 6 → S 7 → S 8 → S 2, the area near the current point is sequentially enlarged and displayed in the loupe 44. Then, when the user presses the left button 13a of the mouse 13 at a position to be the starting point S of the rectangular range while referring to the enlarged display image in the loupe 44, the process proceeds from step S2 to step S3 (S31, S32 in step S3). The process proceeds to step S2), the pressing point is set as the start point S and the end point designation mode is set, and then the process returns to step S2 via step S8.
[0065]
  Next, since the mouse 13 is moved with the left button 13a being pressed, steps S2 to S4, S6, and S7 (steps S71, S72, S73, and S74 are first executed during step S7). The rectangular frames 41 to 43 having the starting point S and the tip position C of the current mouse cursor 40 as diagonals are drawn and stored. Then, the process proceeds to a loupe display position calculation process in step S75, search reference points 1 to 4 are set in steps S751 to S754, and a loupe displayable position search process in step S756 is performed. In this case, since a loupe can be displayed at the lower right of the search reference point, steps S781 and S782 (in steps S801, S802, S803, and S805 are executed), S783, and S794 are performed. Returning to step S757, the loupe 44 is moved in step S77 through steps S758 and S76, and the loupe is displayed at that position. The process passing through such a loop is repeated until the left button 13a is released.
[0066]
  Then, when the user releases the left button 13a of the mouse 13 at the position to be the end point of the rectangular range while referring to the enlarged display image in the loupe 44, the steps S2 to S4, S5 (in step S5, S51, Steps S52, S53, and S54 are executed.) The position where the left button is released is set as the end point, and it is determined that the range specification is completed in Step S8, and the series of range specification processes is completed. .
[0067]
  Next, as shown in FIG. 4D, a case where the loupe cannot be displayed at the lower right position of the mouse cursor 40 and the loupe 44 is displayed at the lower left position of the mouse cursor 40 will be described. In this case, after the start point S is set in the same manner as described above, the mouse cursor 40 is moved in the upper left direction of the start point S. At this time, depending on the position of the mouse cursor 40, the loupe 44 arranged at the lower right of the mouse cursor 40 and the frame line overlap. Specifically, in the process of moving the mouse 13, when step S782 is performed to check whether the loupe 44 can be displayed at the lower right position of the search reference point, the mouse proceeds in steps S801 → S802 → S803 → S804 → S806. The loupe 44 cannot be displayed at the lower right position of the cursor 40. On the other hand, when step S785 for checking whether or not the loupe 44 can be displayed at the lower left position of the search reference point is performed, it is possible to display the loupe 44 at the lower left position of the mouse cursor 40 by proceeding to steps S801 → S802 → S803 → S805. It is.
[0068]
  Next, a case where the loupe 44 is displayed in the rectangular frame as shown in FIG. In this case, after the start point S is set in the same manner as described above, the mouse cursor 40 is moved further to the upper left than in the case of FIG. At this time, since the size of the rectangular frame 46 becomes relatively large, the loupe 44 can be displayed in the lower right direction of the mouse cursor 40. Specifically, in the process of moving the mouse 13, when step S782 for checking whether or not the loupe 44 can be displayed at the lower right position of the search reference point is performed, the mouse proceeds in steps S801 → S802 → S803 → S804 → S805. The loupe 44 can be displayed at the lower right position of the cursor 40.
[0069]
  As shown in FIG. 4 (f), the right display end 48 of the display 11 is also located on the right side of the rectangular frame 47 related to the range specification and at a position relatively close to the rectangular frame 47. As in the case of, the loupe 44 cannot be displayed at the lower right of the mouse cursor 40, and the loupe 44 is displayed at the lower left of the mouse cursor 40. The flow passing process at this time is the same as that described with reference to FIG.
[0070]
  Further, as shown in FIG. 4G, the right display end 48 and the lower display end 49 of the display 11 are located on the right side and the lower side of the rectangular frame 50 related to the range specification and relatively close to the rectangular frame 50. In this case, the loupe 44 may not be displayed even if the four positions around the current point C of the mouse cursor 40 are searched (that is, the display cannot be performed by proceeding from S801 → S806, or S801 → S802 → S803 → The process proceeds from S804 to S806, and display is disabled). In this case, the search is performed at four locations around the vertex T that forms the short side of the rectangular frame 50 together with the current point C. In the case of FIG. 4G, the loupe 44 cannot be displayed at the lower right (steps S781, S782, S783), lower left (steps S784, S785, S786), and upper right (steps S787, S788, S789) of the vertex T. In the search process at the upper left of the vertex T (steps S790, S791, and S792), the loupe 44 can be displayed in the order of steps S801 → S802 →→ S803 → S805.
[0071]
  Like thisReference exampleAccording to the above, when the rectangular range is designated with the mouse cursor 40, the area near the position designated by the mouse cursor 40 is enlarged and displayed in the loupe 44. Therefore, the enlarged image displayed in the loupe 44 is referred to. Thus, the user can perform the range specifying operation efficiently and accurately. Moreover, the bookReference exampleThen, the search unit 33a searches for a position where the loupe 44 having a predetermined display size fits within the display area of the display 11 and does not overlap the rectangular frame line, and the moving unit 33b searches the position detected by this search. 44 is moved, the loupe 44 does not protrude from the display area of the display 11 or overlaps the rectangular frame line, and the enlarged display in the loupe 44 is easy to see.
[0072]
  Next, the present inventionAnother reference exampleWill be described. BookReference exampleIs that the magnifying display reduction unit 33d is provided in the enlargement display control unit 33 of the drawing control unit 24.First reference example aboveIt is different in structure from the one. The loupe area reduction unit 33d is described above.Reference exampleWhen the loupe cannot be displayed around any search reference point according to the above procedure, the size of the loupe is reduced.
[0073]
  Specifically, bookReference exampleThen, instead of the mouse movement process shown in FIG. 8, a mouse movement process as shown in FIG.First reference example aboveIs the same). In the mouse moving process of FIG. 12, when it is determined in step S76 that the loupe cannot be displayed in the display area of the display 11, in step S78, the process of reducing the loupe display size without changing the enlargement magnification is performed. After being performed by the area reduction unit 33d, the process returns to step S75 and the loupe display position calculation process is performed again. Accordingly, for example, even when the display area of the display 11 is very small (for example, a display of a mobile phone), the loupe can be displayed so as to meet the above two conditions, and the loupe area cannot be displayed. Virtually disappear.
[0074]
  When reducing the size of the loupe, the size of the loupe may be reduced by a predetermined ratio, or the shape of the loupe may be changed. At this time, referring to the results in step S801 and step S804, the reduction ratio or the loupe shape may be changed so that these two steps are cleared and the loupe can be displayed.
[0075]
  Next, the present inventionThe fruitThe embodiment will be described. In the present embodiment, a process for checking whether a loupe can be displayed at the search position (First reference example above11), only the former of the two conditions that the loupe fits within the display screen of the display 11 and that the loupe does not overlap with the rectangular frame line is examined (other processing is as follows).First reference exampleIs the same). Therefore, when the loupe overlaps the rectangular frame line, by overwriting the loupe over the frame line, the frame line 51 is not partially displayed and the loupe 52 is preferentially displayed as shown in FIG. The
[0076]
  FIG. 14 shows a flowchart of processing for checking whether or not a loupe can be displayed at the search position in the present embodiment. In this process, first, in step T101, the search unit 33a determines whether or not the substantially circular loupe drawn to have a predetermined radius with the search position as the center falls within the display area of the display 11. If the loupe fits within the display area of the display 11 (T101: YES), the process proceeds to step T102, and if not (T101: NO), the process proceeds to step T103.
[0077]
  In step T102, after the fact that the loupe can be displayed at the search position is stored in the storage unit 33c, the process of checking whether or not the loupe in FIG. 11 can be displayed is terminated. Further, in step T103, after storing in the storage unit 33c that the loupe cannot be displayed at the search position, the process for checking whether the loupe can be displayed is terminated.
[0078]
  As described above, according to the present embodiment, a position where the loupe 52 having a predetermined display size fits in the display area is searched, and the loupe 52 is moved to the position found by this search. Since the frame line 51 is not displayed when the line 52 overlaps the frame line 51, the enlarged display portion in the loupe 52 is easy to see without displaying the frame line. Further, since the display position is determined on the condition that the loupe 52 may overlap the frame line 51 as long as it is within the display area, the loupe 52 is displayed as close to the mouse cursor 40 as possible. The user can perform the range specifying operation more efficiently.
[0079]
  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications can be made. For example, the shape of the designated range is not limited to a rectangle, but may be another shape such as a circle. Further, the search reference position is not limited to the four vertices of the rectangle, and may be set on a side in the middle of the two vertices. In addition, the device used for designating a range is not limited to a mouse, and various pointing devices can be used. Further, the present invention is not limited to a personal computer, and can be widely applied to specify a range on a display such as a mobile phone.
[0080]

  As explained above, the claims1, 5, 9According to the above, when the range is designated with the pointer, the area near the position designated by the pointer is enlarged and displayed in the loupe area. Therefore, the user can efficiently and refer to the enlarged and displayed image in the loupe area. It becomes possible to perform a range specification operation precisely.
[0081]
[0082]
  Furthermore, claims 1, 5, 9According to the above, when a loupe area having a predetermined display size is searched for a position within the display area, the loupe area is moved to a position found by this search, and the loupe area overlaps with the frame line. Since the frame line is not displayed, the enlarged display portion in the loupe area is easy to see without displaying the frame line. In addition, since the display position is determined on the condition that the loupe area may be overlapped with the frame line as long as it is within the display area, the loupe area is displayed as close as possible to the pointer. The range designation operation can be performed more efficiently.
[0083]
  Claim2, 6, 10According to the above, when specifying a rectangular range, the search starts from around the vertex indicated by the pointer, and the search is performed in order from the periphery of the vertex closer to this vertex to the periphery of the vertex farther away. The loupe area is displayed at a nearby location, so that the user can perform the range specifying operation more efficiently.
[0084]
  Claim3, 7, 11Since a search is performed for a plurality of locations around one vertex, it is possible to increase the possibility that the loupe area is displayed as close as possible to the pointer.
[0085]
  Claim4, 8, 12According to the above, when the loupe area cannot be displayed with the predetermined display size, the loupe area is reduced to a size smaller than the predetermined display size, so the loupe area cannot be displayed even when the display area is small. Almost disappears.
