Description

  The present invention relates to an image processing apparatus that performs display control of objects such as characters and graphics, and more specifically, an image processing apparatus that can easily change the layout of an object on a presentation sheet, and a method for controlling the image processing apparatus The present invention relates to a program and a computer-readable recording medium on which the program is recorded.

  Conventionally used presentation software has a function of displaying objects such as characters and figures in one sheet. Such software also has a function of moving a displayed object within the sheet and adding a new object to the sheet.

  With the software as described above, basically, an object (hereinafter referred to as an insertion object) can be inserted by designating an arbitrary position in the sheet. However, when another object (hereinafter referred to as a peripheral object) is displayed around the designated position, the insertion object and the peripheral object overlap each other, so that the insertion object is inserted. I can't.

  For this reason, conventionally, it has been necessary to adjust the positions and sizes of the peripheral object and the insertion object individually and secure the insertion space for the insertion object, and then insert the insertion object.

  This will be described with reference to FIG. FIGS. 8A to 8D are diagrams showing a conventional technique, and are diagrams showing a procedure for inserting an insertion object at a designated position in a presentation sheet.

  As shown in FIG. 8A, it is assumed here that five objects D1 to D5 are displayed in the sheet. Then, it is assumed that the object D1 is moved to the position P surrounded by the peripheral objects D2 to D5. That is, the object D1 is an insertion object, the objects D2 to D5 are peripheral objects, and the position P is a designated position. As shown in the drawing, the space around the position P is smaller than the size of the object D1, so the object D1 cannot be moved to the position P as it is.

  Therefore, as shown in FIG. 8B, the size of the object D1 is reduced. However, just reducing the size of the object D1 still does not fit in the space around the position P.

  If the size of the object D1 is reduced too much, the visibility of the object D1 is lowered. Next, as shown in FIG. 8C, the sizes of the objects D2 to D5 are reduced.

  As a result, a space for moving the object D1 around the position P is secured. As shown in FIG. 8D, the object D1 can be moved to this space.

  As described above, according to the related art, when inserting an object, the user needs to perform a complicated operation for securing a space for inserting the object, and there is a problem that a user burden related to the insertion of the object is large. .

  Here, in Patent Document 1, when the designated destination space is smaller than the insertion object, the insertion object is reduced so as to fit in the space, thereby reducing the burden on the user regarding the insertion of the object. Proposed.

Japanese Patent Laid-Open No. 5-67187 (published on September 9, 1991)

  However, in the invention of Patent Document 1, since the insertion object is reduced in accordance with the movement destination space, there is a problem that the visibility of the insertion object is remarkably lowered when the movement destination space is small.

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide an image processing apparatus and an image processing apparatus capable of inserting an object with a simple operation while ensuring the visibility of the object. A control method, a program, and a computer-readable recording medium on which the program is recorded are realized.

  In order to solve the above-described problems, an image processing apparatus according to the present invention displays a presentation sheet on which an object is arranged, an insertion position in the sheet, and an object that is inserted into the insertion position. An image processing apparatus that accepts an input operation for designating an insertion object and changes the arrangement of the object. When the input operation is accepted, a peripheral object that is an object already displayed around the insertion position is displayed. Peripheral object moving means for moving in a direction away from the insertion position, and object insertion means for displaying a sheet in which the inserted object is inserted in a space generated by moving the peripheral object by the peripheral object moving means. It is characterized by that.

  In addition, in order to solve the above-described problem, the control method of the image processing apparatus according to the present invention displays a presentation sheet on which an object is arranged, an insertion position in the sheet, and an insertion position in the insertion position. An image processing apparatus control method that accepts an input operation for specifying an inserted object that is an object to be inserted and changes the arrangement of the objects, and is already displayed around the insertion position when the input operation is accepted. A peripheral object moving step for moving a peripheral object that is a moving object in a direction away from the insertion position, and a sheet in which the inserted object is inserted in a space generated by moving the peripheral object in the peripheral object moving step is displayed. Including an object insertion step It is a symptom.

  According to the above invention, when an input operation specifying the insertion position in the sheet and the insertion object is received, the peripheral object moving means moves the peripheral object in a direction away from the insertion position, and the object insertion means moves the peripheral object. In this configuration, a sheet in which an insertion object is inserted is displayed in a space generated by the movement.

  As described above, by moving the peripheral object in the direction away from the insertion position to secure the space, the insertion object can be inserted into the sheet-like arbitrary position without reducing the visibility. The input operation necessary for inserting the insertion object is only an input operation for designating the insertion position and the insertion object, which is extremely simple.

  Therefore, according to said structure, it becomes possible to insert an object by simple operation, ensuring the visibility of an object. The insertion of the object may be performed by moving an object already displayed on the sheet to the insertion position, for example, or by newly adding an object not displayed on the sheet. Also good.

  In the image processing apparatus according to the present invention, after the insertion object is inserted, at least one of the insertion object and the peripheral object is reduced so that the insertion object and the peripheral object are within the sheet. It is preferable to provide object reduction means.

  According to the above invention, after the insertion object is inserted, at least one of the insertion object and the peripheral object is reduced so that the insertion object and the peripheral object fit in the sheet.

  As a result, by inserting the insertion object, the insertion object or the surrounding object can be prevented from protruding outside the sheet.

  In the image processing apparatus according to the present invention, the object insertion unit generates an image in a state where the insertion object is inserted in a space generated by the peripheral object moving unit moving the peripheral object, and the object reduction is performed. Preferably, the unit reduces the image generated by the object insertion unit so that the insertion object and the peripheral object can be accommodated in the sheet.

  According to the above invention, the object reduction unit reduces the image in the state where the insertion object generated by the object insertion unit is inserted. For this reason, all objects included in the image are reduced at the same reduction rate.

  Accordingly, the insertion object and the peripheral object can be stored in the sheet and displayed while maintaining the relative size relationship between the insertion object and the peripheral object.

  The image processing apparatus according to the present invention further comprises area dividing means for dividing the sheet into at least two areas based on the insertion position, and the peripheral object moving means is generated by the area dividing means being divided. It is preferable that the objects included in each region are grouped and the surrounding objects are moved by moving the grouped objects away from the insertion position.

  According to the above invention, the peripheral object moving means groups the objects included in the respective areas of the sheet divided by the area dividing means, and moves the grouped objects in the direction away from the insertion position. In this configuration, the object is moved.

  Thereby, even when the number of surrounding objects is large, the process of moving the surrounding objects can be performed efficiently. Note that object grouping refers to processing that enables each object to be handled as one object in a state in which the arrangement relationship between the grouped objects is maintained.

  The image processing apparatus may be realized by a computer. In this case, the image processing apparatus is operated by causing the computer to operate as the peripheral object moving means, the object inserting means, and the object reducing means. A control program for an image processing apparatus realized by a computer and a computer-readable recording medium on which the control program is recorded also fall within the scope of the present invention.

  As described above, when receiving an input operation, the image processing apparatus according to the present invention moves a peripheral object, which is an object already displayed around the insertion position, in a direction away from the insertion position. And an object insertion means for displaying a sheet in which the insertion object is inserted in a space generated by the peripheral object moving means moving the peripheral object.

  Further, the control method of the image processing apparatus according to the present invention includes a peripheral object moving step of moving a peripheral object, which is an object already displayed around the insertion position, in a direction away from the insertion position when an input operation is received. And an object insertion step of displaying a sheet in which the insertion object is inserted in a space generated by moving the peripheral object in the peripheral object movement step.

  Therefore, according to the present invention, it is possible to insert an object with a simple operation while ensuring the visibility of the object.

  An embodiment of the present invention will be described below with reference to FIGS.

[Outline of graphics processing method]
The image processing method according to the present embodiment is an image processing method for changing the layout of an object (for example, a character or a graphic) displayed in a presentation sheet. More specifically, in the above image processing method, when the space around the position where the object is inserted is smaller than the size of the object (inserted object) to be inserted, a plurality of objects (peripheral objects) displayed around the destination A space is secured by moving in a direction away from the destination position. This is a method of automatically performing the process of inserting the insertion object into the secured space.

  Furthermore, in the graphic processing method according to this embodiment, when the entire object after the layout change does not fit in one sheet, the entire object after the layout change is reduced by reducing the entire object after the layout change. A process of displaying in one sheet is performed.

  2A to 2E are schematic views showing an outline of the image processing method of the present embodiment. As shown in FIG. 2A, for example, when the insertion object C is moved to a position P between the peripheral object A and the peripheral object B, the height of the insertion object C is set so that the peripheral object A and the peripheral object Since it is larger than the interval with C, the insertion object C cannot be moved as it is.

  For this reason, as shown in FIG. 2B, the display screen is vertically divided into two on the basis of the position P of the movement destination. Then, all the peripheral objects (peripheral object A in the illustrated example) included in the region located above the position P among the divided regions are moved upward. Similarly, all the peripheral objects (peripheral object B in the illustrated example) included in the region located below the position P among the divided regions are moved downward. That is, the surrounding objects A and B are moved away from each other with the position P as a reference.

  As a result, as shown in FIG. 2C, a space is secured between the peripheral object A and the peripheral object B, and therefore the insertion object C is moved to the secured space.

  If the entire objects A to C after the layout change do not fit on one display screen, as shown in FIG. 2D, the entire moved object is reduced so as to fit within the screen. Thus, the entire objects A to C are displayed on one display screen.

  As described above, in the image processing method according to the present embodiment, the user can change the layout only by performing an operation of designating the insertion object C and its movement destination. Therefore, it is possible to reduce the operation burden on the user when changing the layout.

[Configuration of image processing apparatus]
Next, an image processing apparatus 1 that is preferably used in the image processing method will be described with reference to FIG. FIG. 1 is a block diagram illustrating a schematic configuration of an image processing apparatus 1 according to the present embodiment.

  As shown in FIG. 1, the image processing apparatus 1 includes a touch panel unit 2, a touch panel processing unit 3, a control unit 4, a primary storage unit 5, a secondary storage unit 6, a display data processing unit 7, and a display unit 8. I have.

  The image processing apparatus 1 is a device that displays a presentation screen (sheet) on which objects (graphics, characters, and the like) are arranged on the display unit 8 and performs control for changing the arrangement of the objects in the sheet. The image processing apparatus 1 can be suitably applied to a case where, for example, in an electronic conference system or the like, the sheet is displayed on a large display and the presenter makes a presentation while appropriately moving an object on the sheet.

  The touch panel unit 2 is an input device that receives an input operation of the user of the image processing apparatus 1. Here, the touch panel unit 2 detects a touch operation with the user's finger or a touch pen on the display unit 8, detects a position touched on the display unit 8, and uses these detection results as input operations of the user. It is assumed to be output as a signal indicating the contents. In addition, the touch panel part 2 should just have said function, For example, you may apply the pressure-sensitive type or electrostatic panel widely used conventionally.

  The user can operate the object displayed on the display unit 8 (for example, change the layout of the object) by touching the display unit 8 with a touch pen or the like. As described above, it is preferable that the input operation for changing the layout of the object can be performed on the display unit 8 because the layout can be easily changed during the presentation.

  The touch panel processing unit 3 receives a signal output from the touch panel unit 2 and performs a predetermined process according to the received signal. Specifically, when the touch panel processing unit 3 receives a signal indicating that a touch operation on the display unit 8 has been performed, the touch panel processing unit 3 notifies the control unit 4 to that effect. Further, when the touch panel processing unit 3 receives a signal indicating a position touched on the display unit 8, the touch panel processing unit 3 generates a coordinate value corresponding to the position and stores the coordinate value in the touch panel acquisition coordinate storage unit 51. Furthermore, the touch panel processing unit 3 notifies the control unit 4 that the touch operation has been completed when the signal indicating the touched position on the display unit 8 is not received from the touch panel unit 2.

  The control unit 4 controls the overall operation of the image processing apparatus 1. The control unit 4 includes a pen input processing unit 41, an object management unit 42, an object movement control unit (peripheral object movement unit, object insertion unit, area division unit) 43, and an object reduction unit (object reduction unit) 44. .

  The pen input processing unit 41 generates a trajectory of handwriting input detected by the touch panel unit 2 as an object (pen object), and displays it on the display unit 8. Specifically, when the pen input mode, which is an operation mode for performing a pen input, is set, an image obtained by connecting the locus of coordinates input on the display unit 8 with a line segment is generated as a pen object and displayed. The data processing unit 7 is instructed to display it on the display unit 8. The pen input processing unit 41 notifies the object management unit 42 that a pen object has been newly displayed.

  The object management unit 42 manages an object being displayed by generating or updating object management data of each object (including a pen object) to be displayed on the display unit 8. The object management data is data indicating the type, size, and position on the screen of the object, and is stored in the object management data storage unit 52.

  The object movement control unit 43 executes processing related to the movement of the object displayed on the display unit 8. Specifically, the object movement control unit 43 is based on the coordinates read from the touch panel acquisition coordinate storage unit 51 and a signal sent from the touch panel processing unit 3 when an input operation for moving the object is performed. The object to be moved (inserted object) and the destination position are specified. In addition, the object movement control unit 43 moves the inserted object and the image (layout change) in which the object (peripheral object) existing around the destination of the inserted object is moved based on the object management data read from the object management data storage unit 53. A later image). Then, the object movement control unit 43 instructs the display data unit 7 to display the generated image on the display unit 8. Further, the object management unit 42 is notified of the position of each object after movement, and the object management data in the object management data storage unit 52 is updated.

  Here, the object movement control unit 43 compares the size of the image after the layout change with the display screen size of the display unit 8 read from the screen size storage unit 53, and if the entire object does not fit on the display screen. This is notified to the object reduction unit 44.

  When the object reduction unit 44 receives a notification that the image after the layout change does not fit within the screen, the object reduction unit 44 generates an image that is reduced so that the object after the layout change fits within the screen. Then, the object reduction unit 44 outputs the reduced image to the display data unit 7 and causes the display unit 8 to display the reduced image. The object management unit 42 is notified that the object has been moved and reduced, and the object management data in the object management data storage unit 52 is updated.

  The primary storage unit 5 is a storage area for temporarily storing data when the image processing apparatus 1 executes various processes, and is used as a work area. For the primary storage unit 5, for example, hardware such as ROM or RAM can be used. The primary storage unit 5 includes a touch panel acquisition coordinate storage unit 51, an object management data storage unit 52, and a screen size storage unit 53.

  The touch panel acquisition coordinate storage unit 51 stores the coordinates output from the touch panel processing unit 3.

  The object management data storage unit 52 stores object management data. As described above, the object management data indicates the type, size, and position of the object. Here, as data indicating the type of object, data indicating whether the object is a pen object or a figure is stored, the height of the object is stored as data indicating the size of the object, and the coordinates are stored as data indicating the position of the object. It is assumed that Details of the object management data will be described later.

  The screen size storage unit 53 stores the size of the screen on which the object is displayed, that is, the size (height and width) of the sheet on which the object is arranged. Here, since it is assumed that the sheet is displayed on the entire display screen of the display unit 8, information indicating the size of the display screen of the display unit 8 is stored. However, the present invention is not limited to this example. When a sheet is displayed in a partial area (for example, in a predetermined window) in the display unit 8, information indicating the size of the area is stored. In this case, for example, when the window size is changed, the information stored in the screen size storage unit 53 may be updated accordingly.

  The secondary storage unit 6 is a storage device that stores various data used in the image processing apparatus 1. Here, it is assumed that various programs such as pen software and a touch panel driver are stored as illustrated. The pen software is a program that realizes processing related to a pen object. That is, the function of the pen input processing unit 41 is realized when the control unit 4 reads out and executes the pen software. The touch panel driver is a driver that operates the touch panel 2. That is, the function of the touch panel processing unit 3 is realized by the control unit 4 reading and executing the touch panel driver. For the secondary storage unit 5, for example, a hard disk or the like can be used.

  The display data processing unit 7 performs control to display an image on the display unit 8. That is, the display data processing unit 7 outputs an image to be displayed to the display unit 8 and causes the display unit 8 to display the image.

  The display unit 8 is a display device that displays an image. The display unit 8 may be any device that can display an image. For example, a display device such as an LCD (Liquid Crystal Display) or an organic EL (Electroluminescence) display may be used. Here, it is assumed that the display surface of the display unit 8 is a touch panel.

  The touch panel unit 2 and the display unit 8 may be independent devices that are separate from the image processing apparatus 1. That is, the input device that inputs an instruction to the control unit 4 and the display device that displays an image instructed by the control unit 4 may be connected to the control unit 4 so as to be communicable with each other, and are integrated with the image processing apparatus 1. It may be configured, or may be an independent device externally attached to the image processing apparatus 1. Further, the input device connected to the image processing apparatus 1 is not limited to the touch panel, and may be, for example, a touch pad, a mouse, a tablet, or the like.

[Contents of object management data]
FIG. 3 is a diagram illustrating an example of object management data stored in the object management data storage unit 52. Here, it is assumed that five objects D1 to D5 are displayed on the display unit 8.

  In this case, as shown in FIG. 3, object management data is stored for each of the displayed objects D1 to D5. The object management data is generated and stored by the object management unit 42.

  As described above, it is assumed here that the object management data is the type, height, and coordinates of the object.

  The object type indicates whether each object is a graphic object or a pen object. In the illustrated example, the figure object is described as “Figure”. “Pen object” indicates an object generated by the pen input processing unit 41. Of course, the type of object is not limited to this. By storing the type of object, for example, it can be used for processing such as displaying only a specified type of object.

  The object height indicates the height of each object on the display screen, and indicates the length from the upper end to the lower end of the object. Here, the height of the object on the screen is shown in millimeters, but the height of the object may be expressed as a relative height with respect to the display screen. In this case, the height can also be obtained using the coordinate value.

  Here, since it is assumed that the insertion object is inserted into the space generated by moving the surrounding object in the vertical direction, the object management data includes the height of the object. That is, the “object height” is used to specify the distance to move the surrounding object. For this reason, for example, in a configuration in which a space for inserting an insertion object is generated by moving a peripheral object in the left-right direction, it is necessary to store data indicating “object width” as object management data.

  The coordinates of the object are data indicating the position of the object on the screen, and the coordinate value at a predetermined position on the object is stored as object management data. For example, if the object is a rectangle, the predetermined position may store a coordinate value at any position of the vertex (for example, the upper left vertex).

[Image generated by image processing device]
Next, an image generated by the image processing apparatus 1 will be described with reference to FIG. 4A to 4E are diagrams illustrating examples of images generated by the image processing apparatus 1. Here, as shown in FIG. 4A, five objects D1 to D5 are displayed on the display unit 8, and the case where the object D1 is moved to the position P among these will be described. That is, here, the object D1 is an insertion object, and the objects D2 to D5 are peripheral objects.

  It is assumed that the object management data corresponding to the objects D1 to D5 has already been generated by the object management unit 42 and stored in the object management data storage unit 52.

  As shown in FIG. 4B, the height of the insertion object D1 is h2, the heights of the peripheral objects D2 and D3 are h3, the heights of the peripheral objects 4D and D5 are h4, the peripheral objects D2 and D3, and the peripheral objects. If the distance between 4D and D5 is h1, h2> h1, and therefore the insertion object D1 cannot be moved as it is.

  In such a case, as shown in FIG. 4C, the object movement control unit 43 first divides the area in the sheet up and down on the basis of the position P of the movement destination, and the division occurs. Group objects in each region. In the illustrated example, objects D2 and D3 existing above the position P are grouped as a group G1, and objects D4 and objects D5 existing below the position P are grouped as a group G2. Yes.

  Then, as shown in FIG. 4D, the object movement control unit 43 moves the group G1 and the group G2 away from each other, that is, moves the group G1 upward and the group G2 downward. Thus, a space is secured between the group G1 and the group G2, and the insertion object D1 is moved.

  By such movement (layout change), the total height of the objects becomes h2 + h3 + h4. In the example shown in the drawing, the total height is larger than the height H of the display screen, so that it does not fit on the display screen.

  In such a case, the object reduction unit 44 groups the objects D1 to D5 after the layout change into one group G3 as shown in FIG. Reduce to fit within the screen. The entire objects D1 to D5 after the layout change can be displayed on the screen.

  In this way, when the entire group G3 is reduced, there is an advantage that the relative size relationship of each object is maintained. However, grouping is not an essential process. For example, only surrounding objects or only inserted objects may be reduced without grouping.

  Note that (c) and (d) in FIG. 4 are intermediate images for generating the image of (e), and therefore need not be displayed on the display unit 8. However, when the image of (d) is generated, if the object is within the screen, the generated image of (d) is displayed on the display unit 8 without generating the image of (e). .

[Flow of processing executed by image processing apparatus]
Next, the flow of processing executed by the image processing apparatus 1 will be described with reference to FIG. FIG. 5 is a flowchart illustrating an example of processing executed by the image processing apparatus 1. In the figure, processing after the user selects an insertion object and designates an insertion position is shown.

  As shown in FIG. 5, first, the object movement control unit 43 reads the object management data from the object management data storage unit 52 (S1). Then, the object movement control unit 43 specifies which object is the insertion object using the object management data read in S1 (S2).

  Here, it is assumed that the object is moved by an input operation of dragging and dropping on the display unit 8. For this reason, the object movement control unit 43 reads the coordinates of the position where the display unit 8 is touched from the touch panel acquisition coordinate storage unit 51, and specifies the object existing at these coordinates as the insertion object.

  If it is determined that a plurality of insertion objects are designated, the object movement control unit 43 performs an insertion object grouping process (S3). By this processing, a plurality of inserted objects are handled as one group. The detailed contents of S3 will be described later.

  Next, the object movement control unit 43 specifies the insertion position of the insertion object (S4). As described above, since the dropped position is the insertion position here, the object movement control unit 43 identifies the latest coordinate value stored in the touch panel acquisition coordinate storage unit 51 as the insertion position.

  Next, the object movement control unit 43 checks whether or not the height h2 of the insertion object is larger than the height h1 of the space at the insertion position (S5). The height h2 of the insertion object can be specified from the object management data.

  The height h1 of the space at the insertion position is determined by using the coordinates of the lower end of the surrounding object located above the insertion position and the insertion position using the “object height” and “object coordinates” of the object management data. The coordinates can be specified by obtaining the coordinates of the upper end of the peripheral object positioned below, taking the difference between these Y coordinates, and converting this to millimeters.

  Here, when the height h2 of the insertion object is equal to or less than the height h1 of the space (NO in S5), the object movement control unit 43 moves the insertion object to the space at the insertion position as it is, thereby moving the object An image with the layout changed is generated (S6).

  Then, the object movement control unit 43 outputs the generated image to the display data unit 7 and displays it on the display unit 8 (S18). Further, the object movement control unit 43 notifies the object management unit 42 that the layout has been changed, and the object management unit 42 that has received the notification updates the object management data so as to correspond to the updated layout. . Thereby, the process ends.

  On the other hand, when the height h2 of the insertion object is larger than the height h1 of the space at the insertion position (YES in S5), the object movement control unit 43 divides the display screen into at least two based on the insertion position. (S7). In other words, the object movement control unit 43 divides the area on the screen into a plurality of areas with the insertion position as a boundary. Hereinafter, each divided area is referred to as a divided area.

  Next, the object movement control unit 43 groups the peripheral objects included in the divided areas in each divided area (S8). The grouped peripheral objects are handled as one object. Of course, no grouping is performed in a divided region including only one peripheral object or a divided region including no peripheral object.

  Subsequently, the object movement control unit 43 compares the height h2 of the insertion object with the height h1 of the space at the insertion position, and calculates a shortage of the space at the insertion position necessary for moving the insertion object. (S9).

  Next, the object movement control unit 43 calculates the movement distance of the surrounding objects included in each divided region based on the lack of the space at the insertion position necessary for moving the insertion object calculated in S9. (S10). For example, when the peripheral objects are moved in the vertical direction, the movement distance of each peripheral object may be ½ of the height of the insufficient space.

  Subsequently, the object movement control unit 43 moves the peripheral objects included in each divided region by the movement distance calculated in S10 (S11). Thereby, a space necessary for moving the insertion object to the insertion position is secured.

  Then, the object movement control unit 43 moves the insertion object to the insertion position (S12), and generates an image of the entire object after movement (after layout change) (S13).

  Next, the object movement control unit 43 groups the peripheral objects and the inserted objects after the layout change into one group (S14). Then, the object movement control unit 43 checks whether or not the height h2 + h3 + h4 of the grouped object images is larger than the height H of the display screen (S15). Note that the height of the display screen is stored in advance in the screen size storage unit 53.

  Here, when it is confirmed that the height h2 + h3 + h4 of the image of the entire object is equal to or less than the height H of the display screen (NO in S15), the object movement control unit 43 displays the image generated in S13 as a display data unit. 7 and displayed on the display unit 8 (S18). Further, the object movement control unit 43 notifies the object management unit 42 that the layout has been changed, and the object management unit 42 that has received the notification updates the object management data so as to correspond to the updated layout. . Thereby, the process ends.

  On the other hand, when it is confirmed that the height h2 + h3 + h4 of the image of the grouped object is larger than the height H of the display screen (YES in S15), the object movement control unit 43 notifies the object reduction unit 44 to that effect. To do.

  Upon receiving the notification, the object reduction unit 44 calculates the reduction ratio of the entire grouped objects such that the image height h2 + h3 + h4 of the grouped objects is within the height H of the display screen (S16). Subsequently, the object reduction unit 44 reduces the images of the objects grouped in S14 with the reduction ratio calculated in S16 (S17).

  Then, the object reduction unit 44 outputs an image in which the object reduced in S17 is arranged in the sheet to the display data unit 7 and displays it on the display unit 8 (S18). Thereby, the entire object after the layout change can be displayed in one sheet. Further, the object reduction unit 44 notifies the object management unit 42 that the layout has been changed and the object has been reduced, and the object management unit 42 that has received the notification corresponds to the updated layout and size. Update management data. Thereby, the process ends.

[Inserted object grouping]
Next, details of the insertion object grouping process (S3) of FIG. 5 will be described based on FIG. FIG. 6 is a flowchart illustrating an example of the insertion object grouping process.

  As shown in FIG. 6, in the insertion object grouping process, first, the object movement control unit 43 specifies the grouping range (area in the sheet) of the insertion object (S3a). The grouping range is specified based on a range designation input operation by the user (for example, an operation of dragging on the display unit 8).

  Next, the object movement control unit 43 detects an object included in the range specified in S3a, and specifies the detected object as an insertion object (S3b).

  Finally, the object movement control unit 43 groups the insertion objects specified in S3b (S3c). As a result, the objects within the range specified by the user are grouped, and the objects within this range are handled as one inserted object in the subsequent processing. Therefore, a plurality of objects can be moved together.

[Summary]
As described above, according to the image processing apparatus 1, when an input operation for selecting an insertion object and specifying an insertion position is received, the height h2 of the insertion object is greater than the height h1 of the space at the insertion position. Is larger, the object movement control unit 43 moves the peripheral object in a direction away from the insertion position.

  Then, the object movement control unit 43 inserts the insertion object into the space generated by moving the peripheral object. As a result, even if the space at the insertion position is small, it is possible to insert the object with a simple operation while ensuring the visibility of the object.

  Further, when the object movement control unit 43 confirms that the height of the entire object after the insertion object is inserted exceeds the height of the sheet, the object reduction unit 44 determines that the entire object after the insertion object is inserted. The entire object is reduced so that the height of the object fits within the sheet. As a result, the entire object after the insertion object is inserted can be displayed in a single sheet.

[Modification]
In this embodiment, the example in which the space for moving the insertion object is secured by moving the peripheral object in the vertical direction of the display screen has been described, but the present invention is not limited to this. For example, a space for inserting the insertion object may be secured by moving the peripheral object in the horizontal direction of the display screen.

  FIGS. 7A to 7E are diagrams illustrating other examples of images generated by the image processing apparatus 1, and a case where peripheral objects are moved in the horizontal direction of the display screen. It is a figure which shows the example of. Here, as shown in FIG. 7A, five objects D1 to D5 are displayed on the display unit 8, and among these, the case where the object D1 is moved to the position P will be described.

  As shown in FIG. 7B, the width of the insertion object D1 is w2, the widths of the peripheral objects D2 and D4 are w3, the widths of the peripheral objects D3 and D5 are w4, the peripheral objects D2 and D4, and the peripheral objects D3 and D5. If the interval between and is w1, w2> w1, and therefore, the insertion object D1 cannot be moved as it is.

  In such a case, as shown in FIG. 7C, the object movement control unit 43 first divides the area on the display screen into left and right with reference to the position P of the movement destination, and the division occurs. Group objects in each region. In the illustrated example, objects D2 and D4 existing on the left side of the position P are grouped as a group G1, and objects D3 and objects D5 existing on the right side of the position P are grouped as a group G2. .

  Then, as shown in FIG. 7D, the object movement control unit 43 moves the group G1 and the group G2 away from each other, that is, moves the group G1 to the left and the group G2 to the right. Thus, a space is secured between the group G1 and the group G2, and the insertion object D1 is moved.

  By such movement (layout change), the total object width becomes w2 + w3 + w4. In the example shown in the drawing, the total width is larger than the width W of the display screen, so that it does not fit on the display screen.

  In such a case, the object reducing unit 44 groups the objects D1 to D5 after the layout change into one group G3 as shown in FIG. Reduce to fit within the screen. Thereby, the whole objects D1 to D5 after the layout change can be displayed in one sheet.

  Thus, by moving the peripheral object in the left-right direction of the display screen, it is possible to insert the object with a simple operation while ensuring the visibility of the object. Of course, the moving direction of the peripheral object is not limited to the vertical direction and the horizontal direction as long as the insertion space for the insertion object can be secured. For example, it may be moved in an oblique direction.

  In the above description, the example in which the peripheral object is moved in a predetermined direction has been described. However, an empty space in the display screen may be detected, and the peripheral object may be moved to the detected empty space. Thereby, an empty space can be used effectively. The free space can be detected using the object management data.

  In the above description, the example in which the peripheral objects existing above and below the insertion position are moved has been described. However, the number of peripheral objects to be moved may be one or more. For example, when the surrounding object above the insertion position can be moved to secure the insertion space for the insertion object, only the surrounding object above the insertion position may be moved.

  Furthermore, in the above description, the example in which the peripheral object is moved when the insertion object is moved has been described. However, the present invention can be applied to the case of inserting an object. For example, the present invention can be applied when a new object is added to the display screen. In this case, when an object is added, the process of FIG. 5 is performed.

  Note that the method of adding an object is not particularly limited, and examples thereof include a method of importing an object created by other application software, a method of generating a pen object by performing pen input, and the like.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope shown in the claims. That is, embodiments obtained by combining technical means appropriately modified within the scope of the claims are also included in the technical scope of the present invention.
