For example, a display control processing program may be received from an external device via the communication line I / F unit and stored in the storage unit. Further, the display control process may be executed by reading a display control process program recorded on a recording medium such as a CD-ROM with a CD-ROM drive or the like.

  In step S <b> 101, the reception unit 12 displays the display object 22 on the display screen 20. As an example, as illustrated in FIG. 2, the reception unit 12 displays the display object 22 in the first area 24 and displays an edit button 28 as an editing operator in the second area 24. In addition, the reception unit 12 displays a slider bar 30 on the display screen 20 as a change operator.

  In step S <b> 103, the receiving unit 12 determines whether any operation input to the display object 22 has been received. In the present embodiment, when the contact with the display screen 20 is started, it is determined that any operation input to the display object 22 has been received. If it is determined in step S103 that an operation input has been received (S103, Y), the process proceeds to step S105. If it is determined in step S103 that no operation input is accepted (S103, N), the process proceeds to step S135.

  In step S105, the reception unit 12 determines whether the received operation input is an operation input for the change operation element. In the present embodiment, when the received operation input is a contact with an area corresponding to the slider bar 30 on the display screen 20, it is determined that the received operation input is an operation input for a change operation. If it is determined in step S105 that the accepted operation input is an operation input for the change operator (S105, Y), the process proceeds to step S107. When it is determined that the operation input accepted in step S105 is not an operation input for the change operator (S105, N), the process proceeds to step S133.

  In step S <b> 107, the reception unit 12 determines whether or not the received operation input is an operation (enlargement operation) instructing to increase the display ratio of the display object 22. In the present embodiment, when the knob 30 </ b> A of the slider bar 30 is moved in the plus direction, it is determined that the received operation input is an enlargement operation of the display object 22. When it is determined that the operation input accepted in step S107 is an enlargement operation of the display object 22 (S107, Y), the process proceeds to step S109. Further, when it is determined that the operation input received in step S107 is not an enlargement operation of the display object 22 but an operation (reduction operation) instructing to lower the display ratio of the display object 22 (S107, N) ) Proceeds to step S125.

  In step S109, the first changing unit 14 acquires the display ratio of the display target object 22 when the display target object 22 is enlarged according to the accepted operation input. In the present embodiment, the display ratio of the display object 22 corresponding to the amount of movement of the knob 30A of the slider bar 30 is acquired.

  In step S <b> 111, the second changing unit 16 acquires the size of the first region 24 corresponding to the display ratio of the display object 22 based on the display object enlargement control information 32. For example, when the display ratio of the display object 22 is 120%, the size of the first region 24 is not changed. In addition, when the display ratio of the display object 22 is 160%, the size of the first region 24 is changed according to the display ratio of the display object 22. Further, when the display ratio of the display object 22 is 190%, the size of the first region 24 is set as the entire size of the display screen 20.

  In step S113, the second changing unit 16 displays the display object 22 so that the first area 24 has the size acquired in step S111 and the display object 22 is displayed at the display ratio acquired in step S109. Update the display of. At this time, as shown in FIG. 6 as an example, the second changing unit 16 overlaps the first region 24 with the second region 26 when at least part of the first region 24 and the second region 26 overlaps. The display of the display object 22 is updated so as to be displayed.

  In the present embodiment, the reference point when changing the display ratio of the display object 22 is the center or the center of gravity of the display object 22. However, the reference point for changing the display ratio of the display object 22 is not limited to this, and the position designated by the user may be used as the reference point, and information indicating the reference point is stored in the storage unit in advance. May be.

  In step S115, the control unit 18 determines whether or not the accepted operation input has been completed. In this embodiment, when the contact with the area corresponding to the slider bar 30 on the display screen 20 is released, it is determined that the accepted operation input has been completed. If it is determined in step S115 that the operation input has been completed (S115, Y), the process proceeds to step S117. If it is determined in step S115 that the operation input has not ended (S115, N), the process proceeds to step S107.

  In step S117, the control unit 18 determines whether or not the display ratio of the updated display object 22 is equal to or greater than a predetermined threshold (for example, 180%). If it is determined in step S117 that the display ratio of the display object 22 is greater than or equal to a predetermined threshold value (S117, Y), the process proceeds to step S119. If it is determined in step S117 that the display ratio of the display object 22 is less than the predetermined threshold (S117, N), the process proceeds to step S135.

  In step S119, the control unit 18 hides the change operator displayed on the display screen 20. In this embodiment, as shown in FIG. 7 as an example, the slider bar 30 displayed on the display screen 20 is not displayed.

  In the present embodiment, in step S117, it is determined whether or not the display ratio of the updated display object 22 is greater than or equal to a predetermined threshold, but the present invention is not limited to this. For example, it may be determined whether or not the size of the first region 24 is the entire size of the display screen 20, whether or not the size of the first region 24 is greater than or equal to a threshold value, and the like.

  Alternatively, when the display object 22 is enlarged without performing the process of step S117, the process of step S119 may be necessarily performed.

  Alternatively, in step S117, if the change operation element is displayed on the display screen 20 and at least a part of the change operation element is displayed on the display object 22, an affirmative determination is made in this step. Thus, when the change operator is displayed on the display screen 20 and the change operator and the display object 22 do not overlap, a negative determination may be made in this step.

  Furthermore, in step S117, it may be determined whether or not an instruction for hiding the change operator is accepted. In this case, for example, when an instruction to hide the change operation element is received within a predetermined period (for example, 5 seconds), an affirmative determination is made in this step, and the instruction is not received. Is preferably negative in this step.

  In step S <b> 121, the control unit 18 determines whether or not an instruction to display the change operation element that is not displayed in step S <b> 119 is input. As an instruction to display the change operator, for example, an operation of touching an arbitrary position on the display screen 20 twice, or an operation of continuing touching an arbitrary position on the display screen 20 for a threshold (for example, 3 seconds) or more. An operation of drawing a predetermined shape (for example, a circle, a triangle, etc.) on the display screen 20 can be mentioned. Alternatively, the instruction to display the change operator may be a predetermined operation input using a hardware key.

  If it is determined in step S121 that an instruction to display the change operator is input (S121, Y), the process proceeds to step S123. If it is determined in step S121 that an instruction to display the changing operator is not input (S121, N), this step is repeated until an instruction to display the changing operator is input.

  In step S123, the control unit 18 displays the change operation element hidden in step S119 on the display screen 20, and proceeds to step S135. In this embodiment, as shown in FIG. 8 as an example, a slider bar 30 is displayed on the display screen 20. The position where the slider bar 30 is displayed is, for example, the position where the slider bar 30 is displayed before the slider bar 30 is hidden. Alternatively, the slider bar 30 may be displayed so that at least a part of the slider bar 30 is displayed on the display object 22.

  On the other hand, in step S125, the 1st change part 14 acquires the display ratio of the display target object 22 when the display target object 22 is expanded according to the received operation input. In the present embodiment, the display ratio of the display object 22 corresponding to the amount of movement of the knob 30A of the slider bar 30 is acquired.

  In step S127, the second changing unit 16 acquires the size of the first region 24 corresponding to the display ratio of the display object 22 based on the display object reduction control information 34. For example, when the display ratio of the display object 22 is 120%, the size of the first region 24 is set to the original size before enlargement. In addition, when the display ratio of the display object 22 is 160%, the size of the first region 24 is changed according to the display ratio of the display object 22. Further, when the display ratio of the display object 22 is 190%, the size of the first region 24 is set as the entire size of the display screen 20.

  In step S129, the second change unit 16 displays the display object 22 so that the first area 24 has the size acquired in step S127 and the display object 22 is displayed at the display ratio acquired in step S125. Update the display of.

  In step S131, the control unit 18 determines whether or not the accepted operation input has been completed. In this embodiment, when the contact with the area corresponding to the slider bar 30 on the display screen 20 is released, it is determined that the accepted operation input has been completed. If it is determined in step S131 that the operation input has been completed (S131, Y), the process proceeds to step S135. If it is determined in step S131 that the operation input has not ended (S131, N), the process proceeds to step S107.

  In this way, by continuing the processing of steps S107 to S131 until the operation input is completed, while the operation of changing the display ratio of the display object 22 is being performed, the display of the display object 22 is displayed according to the change operation. The ratio is changed. Thereby, the display ratio of the display object 22 is confirmed in real time by the user.

  On the other hand, in step S133, the reception unit 12 executes processing according to the operation input, and the process proceeds to step S135. For example, when receiving an operation input for the editing operation element, the reception unit 12 performs an editing process on the display object 22 in accordance with the editing operation element for which the operation input has been received.

  In step S135, the reception unit 12 determines whether or not an instruction to end the display of the display target 22 has been input. In the present embodiment, a case where the instruction to end the display of the display object 22 is a predetermined operation input using a hardware key will be described, but the present invention is not limited to this. As an instruction to end the display of the display object 22, for example, an arbitrary position on the display screen 20 is touched twice, and contact at an arbitrary position on the display screen 20 is continued for a threshold (for example, 3 seconds) or longer. And drawing a predetermined shape (for example, a circle, a triangle, etc.) on the display screen 20.

  When it determines with not having input the instruction | indication which complete | finishes the display of the display target object 22 by step S135 (S135, N), it transfers to step S103. If it is determined in step S135 that an instruction to end the display of the display target 22 has been input (S135, Y), the execution of the program for the display control process is ended.

  As described above, in this embodiment, the display screen 20 displays the first area 24 where the display object 22 is displayed and the second area 26 where the editing operator for editing the display object 22 is displayed. A change operation for changing the display ratio of the displayed display object 22 is received. When a change operation is accepted, the display ratio of the display object 22 is changed according to the change operation, and the size of the first region 24 is changed according to the change operation.

  Thereby, for example, when a partial area in the display object 22 is enlarged and displayed, the area in which the partial area is displayed becomes large. Therefore, for example, the scroll distance when scrolling from one point in the partial area to another point is increased, and the number of steps is reduced.

  In addition, although this embodiment demonstrated the case where it was determined in step S117 whether the display ratio of the updated display target object 22 is more than a predetermined threshold value, it is not restricted to this. For example, in a state where the display object 22 is enlarged, the receiving unit 12 receives an instruction to hide the change operation element. When the instruction is received, the control unit 18 displays The change operator displayed on the screen 20 may be hidden.

  In the present embodiment, the case where the slider bar 30 is used as the change operator has been described. However, the present invention is not limited to this, and a plus button, a minus button, or the like may be used as the change operator.

[Second Embodiment]

  Next, a display control apparatus according to the second embodiment will be described.

  In the first embodiment, the case where the first area 24 is displayed on the editing operator when the first area 24 is enlarged has been described. On the other hand, in the second embodiment, a case will be described in which the editing operator is not displayed when the first region 24 is enlarged.

  Since the configuration of the display control apparatus according to the second embodiment is the same as that of the display control apparatus 10 according to the first embodiment, description of each configuration is omitted.

  In the present embodiment, a case where the display control apparatus 10 has a touch panel display as the display screen 20 will be described. Further, in the present embodiment, an instruction to change the display ratio of the display target object 22 is performed by the user moving the contact position on the display screen 20 without displaying the change operator on the display screen 20. The case where is input will be described.

  Examples of the instruction to change the display ratio of the display object 22 include so-called pinch out and pinch in. Pinch out is a state in which a first contact at an arbitrary first position on the display screen 20 and a second contact at a second position different from the first position on the display screen 20 are continued. This is an operation of increasing the distance between the second contacts by moving the position of at least one of the second contacts. The pinch-in is a state in which the first contact at an arbitrary first position on the display screen 20 and the second contact at a second position different from the first position on the display screen 20 are continued. And an operation of bringing the distance between them closer by moving the position of at least one of the second contacts.

  However, the instruction to change the display ratio of the display object 22 is not limited to this. For example, even when the contact is continued at an arbitrary position on the display screen 20 and the operation of moving the contact position up and down is performed. good. In this case, for example, an operation to move the contact position upward may be an instruction to increase the display ratio, and an operation to move the contact position downward may be an instruction to lower the display ratio.

  Alternatively, an operation of moving the contact position to the outer peripheral side or the inner side while the contact at the corner of the display screen 20 is continued may be used. In this case, for example, an operation for moving the contact position to the outer peripheral side may be an instruction to increase the display ratio, and an operation for moving the contact position to the inner side may be an instruction to decrease the display ratio.

  In addition, when the first region 24 is enlarged by the second changing unit 16 and the display ratio of the display object 22 satisfies a predetermined condition, the control unit 18 determines that the second region 26 is not displayed when the enlargement is completed. Control to display. The predetermined condition is, for example, that the display ratio of the display object 22 is equal to or greater than a predetermined threshold (for example, 180%), the first area 24 is the entire size of the display screen 20, and the like. It is.

  Next, the flow of display control processing executed when the display control apparatus 10 according to the present embodiment receives a predetermined execution instruction will be described with reference to the flowchart of FIG. In the present embodiment, the display control processing program is stored in the storage unit in advance, but is not limited thereto. For example, a display control processing program may be received from an external device via the communication line I / F unit and stored in the storage unit. Further, the display control process may be executed by reading a display control process program recorded on a recording medium such as a CD-ROM with a CD-ROM drive or the like.

  In the flowchart of FIG. 9, steps that perform the same processing as in the flowchart of FIG. 5 are denoted by the same reference numerals, and redundant description is omitted.

  In step S <b> 101, the reception unit 12 displays the display object 22 on the display screen 20. In the present embodiment, as shown in FIG. 10 as an example, the display object 22 is displayed in the first area 24 and the edit button 28 is displayed in the second area 24 as an editing operator.

  In step S <b> 103, the receiving unit 12 determines whether any operation input to the display object 22 has been received. In the present embodiment, when the contact with the display screen 20 is started, it is determined that any operation input to the display object 22 has been received. If it is determined in step S103 that an operation input has been accepted (S103, Y), the process proceeds to step S201. If it is determined in step S103 that no operation input is accepted (S103, N), the process proceeds to step S135.

  In step S <b> 201, the reception unit 12 determines whether the received operation input is an operation input for changing the display ratio of the display object 22. In the present embodiment, as described above, the instruction to change the display ratio of the display object 22 is the above-described pinch out and pinch in. Therefore, when there is contact at two positions on the display screen 20, it is determined that the received operation input is an operation input for an operation input for changing the display ratio of the display object 22. If it is determined in step S201 that the accepted operation input is an operation input for the change operator (S201, Y), the process proceeds to step S107. When it is determined that the operation input accepted in step S201 is not an operation input for the change operator (S201, N), the process proceeds to step S133.

  In step S107, the reception unit 12 determines whether or not the received operation input is an enlargement operation. In the present embodiment, when the distance between the two contact positions is increased, it is determined that the accepted operation input is an enlargement operation of the display object 22. When it is determined that the operation input accepted in step S107 is an enlargement operation of the display object 22 (S107, Y), the process proceeds to step S109. If it is determined that the operation input accepted in step S107 is a reduction operation (S107, N), the process proceeds to step S125.

  In step S109, the first changing unit 14 acquires the display ratio of the display target object 22 when the display target object 22 is enlarged according to the accepted operation input. In the present embodiment, the amount of change in the display ratio of the display object 22 is that of the display object 22 when enlarged so that the amount of change is in accordance with the amount of change in the distance between the two contact positions. Get the display ratio. In the present embodiment, the display ratio of the display object 22 is acquired so that the change amount of the display ratio of the display object 22 increases as the change amount of the distance between the two contact positions increases. Not limited to. For example, the display ratio of the display object 22 is acquired so that the change amount of the display ratio of the display object 22 becomes a predetermined fixed value regardless of the change amount of the distance between two contact positions. May be.

  In step S111, the same process as step S111 of the first embodiment is performed, and the process proceeds to step S203.

  In step S203, the control unit 18 determines whether or not the display ratio of the updated display object 22 is equal to or greater than a predetermined threshold (for example, 180%). If it is determined in step S203 that the display ratio of the display object 22 is greater than or equal to a predetermined threshold (S203, Y), the process proceeds to step S205. If it is determined in step S203 that the display ratio of the display object 22 is less than a predetermined threshold (S203, N), the process proceeds to step S135.

  In the present embodiment, in step S203, it is determined whether or not the display ratio of the updated display object 22 is equal to or greater than a predetermined threshold, but the present invention is not limited to this. For example, it may be determined whether or not the size of the first region 24 is the entire size of the display screen 20, whether or not the size of the first region 24 is greater than or equal to a threshold value, and the like. Alternatively, when the display object 22 is enlarged without performing the process of step S203, the process of step S205 may be necessarily performed.

  Or you may determine whether the instruction | indication for making the 2nd area | region 26 non-display was received by step S203. In this case, for example, when an instruction to hide the second area 26 is received within a predetermined period (for example, 2 seconds), an affirmative determination is made in this step, and the instruction is not received. In this case, it is preferable to make a negative determination in this step.

  In step S205, the control unit 18 hides the second area 26 (editing operator) displayed on the display screen 20, and proceeds to step S113. In the present embodiment, as shown in FIG. 11 as an example, the edit button 28 displayed on the display screen 20 is not displayed.

  In the present embodiment, the reference point for changing the display ratio of the display object 22 is set as the midpoint between the two contact positions. However, the reference point for changing the display ratio of the display object 22 is not limited to this, and information indicating the reference point may be stored in the storage unit in advance.

  In step S113, processing similar to that in step S113 of the first embodiment in FIG. 5 is performed.

  In step S115, the control unit 18 determines whether or not the accepted operation input has been completed. In the present embodiment, when the contact on the display screen 20 is released, it is determined that the accepted operation input has been completed. If it is determined in step S115 that the operation input has been completed (S115, Y), the process proceeds to step S135. If it is determined in step S115 that the operation input has not ended (S115, N), the process proceeds to step S107.

  On the other hand, in step S125, the 1st change part 14 acquires the display ratio of the display target object 22 when the display target object 22 is expanded according to the received operation input. In the present embodiment, the amount of change in the display ratio of the display object 22 is that of the display object 22 when the display object 22 is reduced so that the amount of change is in accordance with the amount of change in the distance between the two contact positions. Get the display ratio. In the present embodiment, the display ratio of the display object 22 is acquired so that the change amount of the display ratio of the display object 22 increases as the change amount of the distance between the two contact positions increases. Not limited to. For example, the display ratio of the display object 22 is acquired so that the change amount of the display ratio of the display object 22 becomes a predetermined fixed value regardless of the change amount of the distance between two contact positions. May be.

  In step S127, the same process as step S127 of the first embodiment of FIG. 5 is performed, and the process proceeds to step S207.

  In step S207, the control unit 18 determines whether or not the display ratio of the updated display object 22 is less than a predetermined threshold (for example, 150%). If it is determined in step S207 that the display ratio of the display object 22 is less than the predetermined threshold (S207, Y), the process proceeds to step S209. If it is determined in step S207 that the display ratio of the display object 22 is greater than or equal to a predetermined threshold (S207, N), the process proceeds to step S129.

  In the present embodiment, it is determined in step S207 whether or not the display ratio of the updated display object 22 is less than a predetermined threshold value, but the present invention is not limited to this. For example, it may be determined whether or not the size of the first region 24 is the original size of the display screen 20, whether or not the size of the first region 24 is less than a threshold value, and the like. Alternatively, when the display object 22 is reduced without performing the process in step S207, the process in step S209 may be performed.

  Or you may determine whether the instruction | indication for displaying the 2nd area | region 26 was received by step S207. In this case, for example, if an instruction to display the second area 26 is received within a predetermined period (for example, 2 seconds), an affirmative determination is made in this step, and if the instruction is not received, In this step, a negative determination may be made.

  In step S209, the control unit 18 displays the second area 26 (editing operator) on the display screen 20, and proceeds to step S129. In the present embodiment, as shown in FIG. 10 as an example, the edit button 28 is displayed on the display screen 20. In the present embodiment, the second area 26 is displayed at the position of the second area 26 in the state before the change operation is performed, but the present invention is not limited to this. For example, the position where the second area 26 is displayed and the position of each editing operator in the second area 26 may be adjusted according to the shape of the display screen 20, the shape of the display object 22, and the like. Specifically, when the display screen 20 has a vertically long shape, the second area 26 is displayed on the upper or lower side of the display screen 20, and when the display screen 20 has a horizontally long shape, The second area 26 may be displayed on the right or left side of the display screen 20. Alternatively, in consideration of the highest possibility that the vicinity of the reference point when the display ratio of the display object 22 is changed by the user is most likely, the second region 26 is placed in the region farthest from the reference point. It may be displayed.

  In step S129, the same process as step S129 of the first embodiment in FIG. 5 is performed.

  In step S131, the control unit 18 determines whether or not the accepted operation input has been completed. In the present embodiment, when the contact on the display screen 20 is released, it is determined that the accepted operation input has been completed. If it is determined in step S131 that the operation input has been completed (S131, Y), the process proceeds to step S135. If it is determined in step S131 that the operation input has not ended (S131, N), the process proceeds to step S107.

  On the other hand, in step S133, the reception unit 12 executes processing according to the operation input, and the process proceeds to step S135. For example, when receiving an operation input for the editing operation element, the reception unit 12 performs an editing process on the display object 22 in accordance with the editing operation element for which the operation input has been received.

  In step S135, the same process as step S135 of the first embodiment in FIG. 5 is performed.

  As described above, in the present embodiment, when a change operation for changing the display ratio of the display object 22 is accepted, the second area 26 in which an editing operator for editing the display object 22 is displayed is displayed. The first area 24 is displayed in the area that was left.

  In addition, although this embodiment demonstrated the case where it was determined in step S203 whether the display ratio of the updated display target object 22 is more than a predetermined threshold value, it is not restricted to this. For example, in a state in which the second area 26 is displayed, the reception unit 12 receives an instruction to hide the second area 26. When the instruction is received, the control unit 18 The second area 26 may be hidden.

  Moreover, although this embodiment demonstrated the case where it was determined in step S207 whether the display ratio of the updated display target object 22 is less than a predetermined threshold value, it is not restricted to this. For example, in a state where the second area 26 is not displayed, the receiving unit 12 receives an instruction to display the second area 26. When the instruction is received, the control unit 18 The second area 26 may be displayed.

  In the present embodiment, the case where the pinch out and the pinch in are used as the change operation without using the change operation element has been described. However, the present invention is not limited to this, and the slider bar 30, the plus button, the minus button, and the like are used as the change operation elements. It may be used.

[Third Embodiment]

  Next, a display control apparatus according to the third embodiment will be described.

  In the first embodiment and the second embodiment, the case where the size of the first region 24 is acquired using the enlargement control information 32 and the reduction control information 34 when the first region 24 is enlarged has been described. On the other hand, in the third embodiment, a case where the size of the first region 24 is calculated based on the display ratio of the display object 22 will be described.

  Since the configuration of the display control apparatus according to the third embodiment is the same as that of the display control apparatus 10 according to the first embodiment and the second embodiment, description of each configuration is omitted.
