Detailed Description
Hereinafter, an embodiment for carrying out the present invention will be described with reference to the drawings. For convenience of explanation, the display device of the present invention is applied to a terminal device integrated with a touch panel (touch panel) as an example of the embodiment, but any display device may be applied as long as an object can be drawn and arranged by an operation input of a user.
[1. first embodiment ]
[1.1 Overall Structure ]
First, fig. 1 shows an external appearance of a display device 10 to which the display device of the present invention is applied. The display device 10 is a display device such as a liquid crystal display, and is constituted by a touch panel that can be touch-input.
Here, an operation input from the user such as a touch, a flick (flick), or a slide can be accepted through the touch panel. As a method of detecting such a touch, for example, a capacitive touch panel or a pressure-sensitive touch panel may be used. That is, any device may be used as long as it can appropriately accept operation input by the user, such as touch.
The display device 10 is not limited to a general touch panel display, and may be a computer, a tablet device, a smart phone, a car navigation device, or the like.
[1.2 functional Structure ]
Next, a functional configuration of the display device 10 in the present embodiment will be described with reference to fig. 2. As shown in fig. 2, the display device 10 includes a control unit 110, an operation detection unit 120, a display unit 130, and a storage unit 140.
The control unit 110 is a functional unit for controlling the entire display device 10. The control unit 110 reads and executes various programs stored in the storage unit 140 to realize various functions, and is configured by, for example, a cpu (central Processing unit).
In addition, when the control unit 110 is configured as a touch panel, for example, it controls the drawing on the display screen (operation detection unit 120), the display of an object such as an input image, or the display of an image input from another image input device.
The operation detection unit 120 is a functional unit for detecting an operation from a user. For example, the display unit 130 is a touch panel or the like integrally formed therewith. The operation detection method may be any of a pressure-sensitive type such as a capacitance type or a resistance film type, an infrared type, an electromagnetic induction type, and the like.
The display unit 130 is a functional unit for displaying various information to the user or displaying a page on which an object is drawn and arranged. For example, the display device is constituted by a Liquid Crystal Display (LCD), an organic EL display, or the like.
The storage unit 140 is a functional unit that stores various programs and various data necessary for the operation of the display device 10. The storage unit 140 is configured by, for example, a semiconductor memory such as ssd (solid State drive) or a Disk such as hdd (hard Disk drive).
Here, the storage unit 140 stores page information 142 and parameter information 144, and also stores a main program 152, a page extension program 154, an extension menu update program 156, and a page display update program 158.
The page information 142 stores information about a page. For example, as shown in fig. 3 (a), in the present embodiment, page sizes (e.g., "(0, 0) - (1919,1079)") and objects to be arranged are stored.
Here, a page (sheet) is image data that can be configured, and that depicts various objects, or a layer (layer) and a canvas (canvas). When a handwritten object is drawn by a user, for example, the handwritten object is configured on a page.
In general, the size of the displayed page matches the size of the display area determined by the display unit 130. Here, the user can use the object as an electronic blackboard by arranging and drawing the object.
In addition, a page may also have multiple pages. In this case, an operation such as page changing can be performed by a predetermined operation (for example, a swipe operation by a user).
As described above, the page size, i.e., the page size, often coincides with the display area, but may be different. Thus, an object larger than the page size can be arranged and drawn, or when the object is not received in the display area, the arrangement, drawing, and the like can be added.
The page size refers to the size of the page, and the page information 142 stores the size of the page. In fig. 3 (a), the vertical x horizontal size is stored as an example of the page size. In addition, the coordinates (relative coordinates or absolute coordinates) may be stored, or the number of pixels may be stored. In addition, in the case where the page is a file (file), the attribute of the file may also be referred to.
The object to be allocated on the page is stored in the allocation object. The object (object) is an object drawn by a user or an object to which another file is pasted. The contents of the object include the arrangement coordinates, size, stroke data (stroke data), file data (file data) such as text data, image, and sound, document data (document data), and the like of the object. As a method of drawing an object on a page based on information of the object, any known method may be used.
In the present specification, the term "page size expansion" is included when only the term "page expansion" is mentioned. Specifically, in the case of "downward expansion of the page", it means that the page size is expanded downward.
The parameter information 144 stores parameters and attributes related to pages, parameters used when executing programs, and the like. For example, as shown in fig. 3 (b), an expanded size (e.g., "200"), a display area (e.g., "0, 0) - (1919,1079)"), a display magnification (e.g., "100%"), and a page maximum size (e.g., "12000,19800)") are stored.
Expanding the size in the processing described below, what is stored is the size that is expanded when the page is expanded. The expansion dimension may be changed in the vertical and horizontal directions, or the like. In the present embodiment, the number of pixels (pixels) is stored, but may be a percentage or an object that is variable according to a user operation.
The display area indicates a range of the page currently displayed on the display device 10. In the present embodiment, the coordinates are expressed as relative coordinates or absolute coordinates.
The display magnification stores the corresponding magnification of the page and the display area. The magnification of the display page and the objects arranged on the page are shown, and can be arbitrarily set by the user.
The maximum dimension of the page is the dimension that can be maximally expanded in the case of expanding the page. In this embodiment, the page expansion operation is not accepted in the case of exceeding the maximum size of the page. As the maximum size of the page, the vertical and horizontal sizes may be stored as shown in fig. 3 (b), and any contents may be stored. Further, the maximum size may not be set according to the system.
The main program 152, the page expansion program 154, the expansion menu update program 156, and the page display update program 158 are each read and executed by the control unit 110, and thereby functions corresponding to the respective programs are executed. The processing executed by these programs is explained below.
In the present embodiment, the display device 10 performs display, drawing, and control as one device, but the controller may be another device. For example, the present invention can also be implemented by a drawing device (e.g., a computer) connected to a display device that can detect a touch by USB/HDMI (registered trademark) or the like.
[1.3 basic description ]
Next, a concept of the present embodiment will be described. In the present embodiment, an expansion menu (menu) is displayed in the display area. Then, the user touches (selects) a predetermined area (for example, an expansion button in the present embodiment) of the expansion menu to expand the page in a direction corresponding to the predetermined area.
Fig. 4 shows an example of the expansion menu. Fig. 4 (a) shows the expansion menu W10 as a simple expansion menu. In the expansion menu W10, a preview image of the display area is displayed in the area R10. Further, the expansion menu may be one in which the preview image is not displayed, or the preview image may be selectively displayed or not displayed.
Around the region R10, a selection button B10 is displayed. The selection button is displayed in the up-down, left-right direction. For example, in the expansion menu W10, an up direction selection button B10U, a right direction selection button B10R, a down direction selection button B10D, and a left direction selection button B10L are displayed.
Here, the user touches (selects) the selection button to expand the page size in the corresponding direction. Here, the page size expansion means an expansion of an area in which the user can configure the object.
In addition, when the page size is expanded, the expansion menu can be expanded together, and the original state can be maintained. When the expansion menu is displayed in an expanded state, the display area R10 may be expanded, or the preview image displayed in the area R10 may be displayed again in the same size. In addition, when the extension menu has the same size, the preview image displayed in the area R10 may be displayed again.
In addition, the expansion menu may be expanded/reduced in size according to the operation of the user, or may be in other manners. For example, as shown in the expansion menu W12 in fig. 4 (B), the shape of the selection button B12 may be different. For example, in fig. 4 (B), it is shown in a triangle as shown by the selection button B12R. Further, as a button for closing the expansion menu, a region R12 may be displayed. The area R12 of the button for closing the expansion menu may be selectable to display/non-display, or may be switched to display/non-display according to the size of the expansion menu.
As shown in the expansion menu W14 in fig. 4 (c), the selection button may be set to not be displayed and the selection area B14 may be set. For example, the user may select the selection area B14U on the upper side of the expansion menu W14 to recognize that the selection button has been pressed. The selection button and the selection area may be switched by the user, or may be switched according to the size of the expansion menu.
The operation of page size expansion is explained with reference to fig. 5. Fig. 5 (a) is a diagram showing a basic state. For example, the page is defined as the size of (0,0) - (X, Y) in a coordinate manner. In addition, the coordinates may be relative coordinates or absolute coordinates. Note that the page is a portion indicated by a thick line. In this case, the display area is the same size as the page.
Here, when the operation of expanding the page in the right direction is performed, the page size is expanded as shown in fig. 5 (b). That is, the size of the page is expanded in the right direction by the defined expansion size. For example, in the case where the extended size is stored in the parameter information 144 as "a", the size of the page becomes (0,0) - (X + a, Y).
As a method of expanding the page size, a method of re-defining the page size after expansion in the right direction in a coordinate manner, a method of expanding the page size by adding an expanded area to the current page area with the expanded area as an expanded area, or the like can be considered.
In addition to this, in the case of expanding the page size in the upward direction, the page size is changed from (0,0) - (X, Y) to (0, 0-a) - (X, Y).
In the present embodiment, the page is expanded by the size of the expansion size stored in the parameter information 144, but the expansion size may be calculated. For example, when a page in the vertical direction is expanded, a page of "new page size banner/4 × page size banner" may be expanded, and when a page in the horizontal direction is expanded, the page may be calculated as "new page size banner/4 × page size banner". That is, in this case, if the expansion direction is selected, the expansion is performed by only one-fourth of the new page size. The fourth may be a fifth, a third, or other value.
In the case of expanding a page, if the page size reaches a limit, the page may not be enlarged.
In fig. 5 (b), the display region is a range indicated by a thin line. Namely, (a,0) - (X + a, Y) are display regions. As described below, various methods are conceivable for designating an area as a display area.
As described above, the present embodiment enables the user to easily and intuitively expand the page size by using the expansion menu. In addition, since the page size is secured to a required size, the memory capacity can also be small. For example, even in a device such as a smartphone or a tablet (tablet) whose processing speed or memory capacity is not large, the device can be executed with a small load.
[1.4 flow of treatment ]
Next, the flow of processing in the present embodiment will be described with reference to the drawings.
[1.4.1 Main treatment ]
The main processing will be described with reference to fig. 6. The main process is a process that the control unit 110 reads and executes the main program 152 stored in the storage unit 140.
First, when the call-out (call-out) operation of the expansion menu is performed, the expansion menu is displayed (step S1002; YES → S1004).
Next, when the button of the expansion menu is selected (e.g., touch-operated) (step S1006; YES), page expansion processing is executed (step S1008). The page expansion process will be described with reference to fig. 7.
When the size of the page is changed by executing the page expansion processing (step S1010; YES), an expansion menu update processing for updating the expansion menu (step S1012) and a page display update processing for updating the display of the page (step S1014) are executed. Thus, the display of the expansion menu or the page is updated according to the instruction of the user or the preset content. In addition, details will be described with reference to fig. 8 and 9.
In the present embodiment, the page display update processing of step S1014 is executed after the expansion menu update processing of step S1012 is executed, but the order of the processing is not limited. That is, step S1014 may be executed first, and then step S1012 may be executed. Further, step S1012 and step S1014 may be executed as parallel processing.
Thereafter, the processing is repeatedly executed from step S1006. In addition, the expansion menu that has been displayed once may be set to be not displayed. For example, when the operation to set the extension menu to non-display is performed after step S1014, the extension menu is switched to non-display, and the process is repeatedly executed from step S1002.
When the extension menu is not called out (step S1002; No) or when the extension button is not selected although the extension menu is displayed, the object arrangement processing is executed (step S1020).
The object arrangement processing is processing in which the user arranges objects on a page, and executes, for example, processing in which handwritten objects are arranged by handwriting input, text objects are arranged by text input, or content files in which images, sound animation, and the like are arranged are pasted. The object to be arranged can be moved, changed, enlarged/reduced, or deleted. These object arrangement processes are processes realized by, for example, a conventional whiteboard function, and therefore detailed description thereof is omitted.
Here, when the end processing is selected, the main processing is ended (step S1022; yes). On the other hand, in the case of continuing the processing, the processing is repeatedly executed. Specifically, when the expansion menu is displayed (step S1024; YES), the process is repeatedly executed from step S1006. Further, when the expansion menu is not displayed (step S1024; NO), the processing is repeatedly executed from step S1002.
It is needless to say that the expansion menu itself may be moved or changed in size. In addition to this, the display attributes, i.e. the color, the transmittance, etc. may be changed.
[1.4.2 Page expansion treatment ]
The page expansion process will be described with reference to fig. 7. The page expansion process is a process that the control unit 110 reads and executes the page expansion program 154 stored in the storage unit 140.
First, the expansion direction of the page size is determined (step S1102). In the present embodiment, an expansion button in which the direction of the page is to be expanded is selected from among the displayed expansion buttons. That is, the direction corresponding to the selected expansion button is determined.
Next, whether or not the page size can be expanded is determined (step S1104). Here, the determination whether the page size can be expanded is, for example, a determination whether the processable page size is exceeded or a determination whether the maximum size set by the user is exceeded.
In the present embodiment, it is determined whether or not the page size exceeds the maximum size. Here, the page maximum size is a value stored in the parameter information 144. And when the page size exceeds the maximum size, determining that the expansion of the page cannot be carried out.
When the page size is expandable (step S1104; YES), an expanded page size is calculated (step S1106). For example, the expansion size is read from the parameter information 144, and the page size is expanded by calculating the area of the page to be expanded by the size to be expanded in the direction specified in step S1102 (step S1108).
[1.4.3 expansion Menu update processing ]
The expansion menu update process will be described with reference to fig. 8. The extended menu update process is a process that the control unit 110 reads and executes the extended menu update program 156 stored in the storage unit 140.
It is determined whether or not updating of the display of the expansion menu is necessary (step S1202). Here, whether or not the display update of the expansion menu is necessary can be determined by various methods.
For example, it is determined whether or not the preview area is displayed in the expansion menu. When the extended menu displays the preview area, it is determined that the display update of the extended menu is necessary, and when the preview area is not displayed, it is determined that the display update of the extended menu is unnecessary.
In addition, it is also possible to determine whether or not the size of the expansion menu is changed. When the size of the expanded menu is changed, it is determined that the display update of the expanded menu is necessary, and when the size of the expanded menu is not changed, it is determined that the display update of the expanded menu is unnecessary.
In this embodiment, as an example, in order to describe a case where the display update of the expansion menu is necessary, the process proceeds to step S1204 to execute the display update processing of the expansion menu (step S1204). Here, various processes are conceivable as the display update process of the expansion menu, and two processes are described here.
(a) Resizing preview regions
The display of the expansion menu is updated so that the entire page is displayed by changing the size of the preview area displayed in superimposition with the expansion menu. This allows the user to confirm the preview of the entire page in the preview area.
(b) Expand display menu
The size of the expansion menu is changed together with the expansion of the page. Here, the preview display of the page is performed in the expansion menu. Therefore, when the page size is expanded, the expansion menu is also expanded to display. In this case, the magnification (reduction ratio) of the preview display of the page displayed in the preview area is not changed before and after the expansion of the page.
When the display of the expansion menu is updated, the display area displayed on the display unit 130 becomes a part of the expanded page, and therefore, which part is displayed on the page is displayed, and the display is recognized and displayed in accordance with the current display area (step S1206). Thus, the user can easily confirm which region is currently displayed in the page.
Here, the recognition display corresponding to the current display area is described with respect to an example in which the displayed area is a frame line display in the present embodiment. In addition, various methods such as displaying gray outside the region or displaying the gray with changing the brightness of the region may be employed.
In addition, when the page is expanded but the expanded page is included in the display area, the entire page is displayed. In this case, the entire display area may be displayed without being recognized.
[1.4.4 Page display update processing ]
The page display update process will be described with reference to fig. 9. The page display update process is a process that the control unit 110 reads and executes the page display update program 158 stored in the storage unit 140.
It is determined whether or not display update of the page is required (step S1302). Here, as the determination whether or not the display update of the page is necessary, for example, whether or not the expanded page is received in the display area is determined. In addition, whether or not to update the display may be set for the user, and whether or not to update the display may be determined based on the setting.
Here, in the case of updating the page display, it proceeds to step S1304 to execute the processing.
Specifically, the display area is reset so as to include an expanded area, which is an expanded area (step S1304). Since the display area is reset, the display is updated (step S1306), and the display of the page is updated.
[1.5 working examples ]
An operation example in the present embodiment will be described with reference to fig. 10. Fig. 10 (a) shows an example of a display screen W100 on which a page included in the display area is displayed. A plurality of objects are arranged in a page, and the expansion menu M100 is called and displayed so as to overlap with the page. In addition, the expansion menu M100 is displayed so as to overlap with the page in fig. 10 (a), but may be displayed in another area.
In addition, the expansion menu M100 displays a preview of the currently displayed page in the preview area R100. Further, the expansion menu M100 has expansion buttons displayed in four directions, up, down, left, and right. The preview area R100 is displayed so as to be included in the expansion menu M100, but may be displayed in an area different from the expansion menu.
Here, when the expansion button B100 in the right direction is selected by the user through a touch operation (tap operation), the screen transitions to the display screen W110 in fig. 10 (B).
The display screen W110 is expanded in the right direction by the page size, and the entire page is moved in the left direction so as to include the expanded region R114. That is, the object placed on the page moves in the left direction by the size of the expanded page.
In addition, a preview image of the entire new page is displayed in the preview area R110 displayed in the expansion menu M110. At this time, in the preview image, since the size of the entire page is different from the size of the displayed page, the frame line M112 for identifying and displaying the position of the currently displayed page is displayed.
As shown in fig. 10 (c), the size of the expansion menu M120 may be increased by expanding the page size. In this case, the size of the preview area R120 also becomes larger together with the size of the expanded page.
In addition, in the case of (c) of fig. 10, the present display area is also indicated by a frame line M122.
In addition, by displaying the position of the page currently displayed in the preview area in a recognized manner, the user can easily recognize which part of the page is currently displayed and how much the page is expanded.
As described above, according to the present embodiment, a page can be easily expanded by using the expansion menu.
[2. second embodiment ]
The second embodiment will be explained. This embodiment is an embodiment of a case where the display of a page is not updated. Specifically, as described above, for example, the entire page is stored in the display area while the page is expanded, or the user performs setting, operation, or the like so as not to update the display of the page. The functional configuration and the processing flow in the present embodiment are basically the same as those in the first embodiment, and therefore, differences will be mainly described.
Specifically, a description will be given of a process in a case where it is determined that updating of the display is not necessary in the page display update process of fig. 9 (step S1302; no). In step S1302, it is determined that the display does not need to be updated, and the display of the page remains as it is even if the page size is increased.
Fig. 11 (a) shows a display screen W200 as an example of the display screen in the second embodiment. An expansion menu M200 is displayed on the display screen W200. The display screen W200 in fig. 11 (a) is a display screen after the page size has been expanded in the right direction (for example, after fig. 10 (a)).
The display screen in the present embodiment does not update the display of the page even after the page size is expanded. That is, the currently displayed object is displayed in the same position both before and after dilation.
Thus, in the present embodiment, even when the user performs the expansion operation, the page size is expanded, but the object can be displayed at the position in the original state.
As another example, fig. 11 (b) shows a display screen W210 after the page size is expanded downward. Fig. 11 (b) shows a preview image in which the page size has been expanded downward. Note that the size of the expansion menu M210 is not changed from (a) of fig. 10, and the size of the preview area is also the same. That is, the preview image is displayed in a reduced size so as to be displayed in its entirety.
As described above, although the first embodiment and the second embodiment are described in the present specification, it is needless to say that the combination of the embodiments may be performed within a range not inconsistent with each other.
[3 ] third embodiment ]
The third embodiment will be explained. This embodiment is an embodiment in which the preview display is not performed in the extension menu. The functional configuration and the processing flow in the present embodiment are basically the same as those in the first embodiment, and therefore, differences will be mainly described.
Fig. 12 shows an example of a display screen W300 according to the present embodiment. The expansion menu M300 displayed on the display screen W300 displays only the expansion button without displaying a preview of the page.
Therefore, in the present embodiment, the update process is not required in the expansion menu update process of step S1202 (step S1202; no). That is, the same expansion menu is displayed also after expanding the page.
As described above, according to the present embodiment, an expansion menu in which only operation buttons for expanding a page are displayed can be used. Thus, for example, when the display area is not large, or when a large page is desired, a small expansion menu can be displayed.
[4. fourth embodiment ]
A fourth embodiment will be explained. This embodiment provides a case where the operation of the display area can be changed without changing the size of the expansion menu. The functional configuration and the processing flow in the present embodiment are basically the same as those in the first embodiment, and therefore, differences will be mainly described.
The fourth embodiment is obtained by replacing the expansion menu updating process of fig. 8 in the first embodiment with the process of fig. 13.
First, it is determined whether or not the page size exceeds the size of the current display area (step S2002). If the page size exceeds the size of the current display area (step S2002; yes), the process of displaying a scroll bar in the extended menu is executed.
Specifically, first, the page size and the size of the display area are compared to determine whether the size of the page size in the lateral direction exceeds the size of the display area (step S2004). Then, in the case of exceeding the display area, the horizontal scroll bar is displayed (step S2004; YES → step S2006).
Next, it is determined whether or not the size of the page size in the vertical direction exceeds the display area (step S2008). When the size of the page size in the vertical direction exceeds the size of the display area, a vertical scroll bar is displayed (step S2008; YES → step S2010).
Then, the current display area is displayed in the preview area in a recognized manner (step S2012). In the present embodiment, for example, a position surrounding the display area with a frame line is displayed, but for example, the color, the luminance, or the like may be changed. Further, the color, the brightness, or the like may be changed at a position other than the display region.
In addition, although the present processing is described with respect to the processing of displaying a scroll bar, the scroll bar may not be displayed in a case where it is not necessary. For example, in the case of no processing in step S2004, the scroll bar may be set not to be displayed.
Fig. 14 (a) shows an example of a display screen W400 according to the present embodiment. The expansion menu M400 displayed on the display screen W400 previews a page in the area R400. Here, in the present embodiment, the page size exceeds the display area. In this case, a scroll bar is displayed in the scroll operation region R402. The user can switch the display area in the page by operating the scroll bar displayed in the scroll operation area.
That is, in the present embodiment, the extension menu is provided with an extension operation area for displaying the extension button and a preview display area for displaying the preview image.
Further, a scroll operation area is provided in the preview display area. The scroll operation area is included in the preview display area in the present embodiment, but may be another area. For example, the expansion operation area and the scroll operation area may be integrated. In addition, as represented by a scroll operation area, each area may be switched between display and non-display as necessary. Particularly in the case where the scroll operation area does not need to be displayed, it is needless to say that it does not need to be displayed intentionally.
For example, in the display screen W410 of fig. 14 (b), R412 and R414 are displayed as scroll operation areas in the preview display area R410 of the expansion menu M410. As described above, the user can easily move the position of the preview image by displaying the vertical and horizontal scroll bars.
[5. fifth embodiment ]
A fifth embodiment will be described. In the present embodiment, when a page is expanded, the display area is reduced so as to include the entire page. The functional configuration and the processing flow in the present embodiment are basically the same as those in the first embodiment, and therefore, differences will be mainly described.
The fifth embodiment is obtained by replacing the page display update processing of fig. 9 in the first embodiment with the processing of fig. 15.
First, it is determined whether or not the page size exceeds the size of the current display area (step S3002). If the page size exceeds the size of the current display area (step S3002; yes), the display magnification is set so that the entire page is displayed in the display area (step S3004). Then, the display of the page is updated according to the set display magnification (step S3006).
Fig. 16 (a) shows an example of a display screen W500 in the present embodiment. The expansion menu M500 displayed on the display screen W500 previews a page in the area R500. Here, in the present embodiment, the page size exceeds the display area. In this case, the entire page is reduced and the entire page is displayed on the display screen W500. In addition, an example of expanding the page size in the right direction is shown.
The display screen W510 in fig. 16 (b) is a diagram in which the page is expanded upward. In this case, since the page size exceeds the display area, the entire page is displayed on the display screen W510 by reducing the entire page to be displayed.
Here, as the process of performing reduction, for example, a page is reduced and displayed so that the maximum size in the x direction and the y direction is accommodated in the display area. For example, when the page size is expanded in the right direction (fig. 16 (a)) and then the page size is expanded in the upper direction (fig. 16 (b)), the entire display page is reduced so that both the x direction and the y direction of the page size are included in the display area.
As described above, in the present embodiment, when a page is expanded, the user can view the entire page by automatically changing the scale ratio (representational fraction).
[6 ] sixth embodiment ]
A sixth embodiment will be described. In this embodiment, when expanding a page, the preview of the expansion menu is displayed in a reduced size so as to include the entire page. The functional configuration and the processing flow in the present embodiment are basically the same as those in the first embodiment, and therefore, differences will be mainly described.
The sixth embodiment is obtained by replacing the expansion menu update processing of fig. 8 in the first embodiment with the processing of fig. 17.
First, it is determined whether or not the page size exceeds the size of the current display area (step S4002). If the page size exceeds the size of the current display area (step S4002; YES), the display magnification is set so that the entire page is displayed in the display area (step S4004). Then, the preview display of the expansion menu is updated in accordance with the set display magnification (step S4006).
Fig. 18 shows an example of a display screen W600 according to the present embodiment. The expansion menu M600 displayed on the display W600 previews a page in the area R600. Here, in the present embodiment, the page size exceeds the display area. In this case, the preview display corresponding to the page is reduced, and the entire expansion menu M600 is displayed. As described above, in the present embodiment, when expanding a page, the user can easily select the entire page in the expansion menu by automatically changing the scale ratio of the preview display of the expansion menu.
[7 ] seventh embodiment ]
A seventh embodiment will be described. This embodiment is an embodiment in which the display magnification of the preview display area can be arbitrarily changed in the expansion menu, and the size of the expansion menu can be changed. The functional configuration and the processing flow in the present embodiment are basically the same as those in the first embodiment, and therefore, differences will be mainly described.
In the seventh embodiment, the expansion menu M700 shown in fig. 19 is displayed as the expansion menu. The expansion menu M700 is displayed, for example, in place of the expansion menu displayed in the first embodiment or the sixth embodiment.
In the expansion menu M700, a preview image of the entire page is displayed in the preview display area R700. The preview image of the entire page can be changed to an arbitrary display magnification by a display magnification selection button B700 described below.
In addition, a menu display operation area R710 and a preview image magnification change operation area R720 are provided.
The menu display operation area R710 is an area in which function buttons and the like for operating the extension menu M700 are displayed. In this area, for example, a function button and a selection area for operating the expansion menu M700 such as moving the expansion menu M700, expanding/reducing, setting to non-display, and dividing the area are displayed.
In the present embodiment, a display magnification selection button B700 and an equal magnification button B710 are displayed in the preview image magnification change operation region R720. By selecting the display magnification selection button B700, the display magnification of the preview image can be changed. Further, the magnification of the display can be changed to 100% at all times by selecting the equal magnification button B710. The size of the expansion menu M700 may be changed in accordance with the preview display in accordance with the display magnification, or the scroll display may be enabled.
These regions may be displayed as a single body or may be displayed in different regions (e.g., different regions from the expansion menu). In addition, a desired function may be displayed as needed.
[8 ] eighth embodiment ]
The eighth embodiment will be described. The present embodiment is an embodiment for explaining an operation in a case where a plurality of expansion buttons are selected. The functional configuration and the processing flow in the present embodiment are basically the same as those in the first embodiment, and therefore, differences will be mainly described.
Fig. 20 is a diagram for explaining an operation example in the present embodiment. Fig. 20 (a) shows an example of a display screen W800 in the present embodiment. An expansion menu M800 is displayed on the display screen W800.
Here, the expansion button B810 for expanding the upper direction and the expansion button B820 for expanding the right direction may be simultaneously selected by the user. In this case, for example, in step S1102 of the page expansion process of fig. 7, the upward direction and the right direction are determined as the expansion directions. Therefore, the page is expanded in the upward and right directions, and the page size is expanded.
Fig. 20 (b) shows the display screen W810 after the page size is expanded. The page is expanded to the upper right (up + right), and display update of the page is performed. In addition, it can also be recognized that the page size is expanded to the upper right direction by confirming the expansion menu M810.
As described above, according to the present embodiment, even when it is desired to expand the page size in a plurality of directions, the page size can be expanded in an easy manner.
In the present embodiment, the description has been given of an example in which two expansion buttons are selected to expand the page in two directions, but the center of the two expansion buttons may be selected. That is, the page is expanded by selecting between the expansion button B810 and the expansion button B820 of fig. 20 (a) (i.e., the upper right of the expansion menu M800).
That is, a direction from the center of the expansion menu (center of the preview image) (including a direction from the vicinity of the center) is determined, and the page is expanded with respect to the determined direction.
For convenience of explanation, the explanation will be given in two directions, but for example, the processing may be performed in three directions or four directions (omnidirectional directions). Further, it is also possible to switch between an operation in which a plurality of directions are expandable and an operation in which only one direction is expandable.
[9 ] ninth embodiment ]
A ninth embodiment will be described. This embodiment is an embodiment in which the size of the expansion can be set in stages by a switching operation when expanding the page. The functional configuration and the processing flow in the present embodiment are basically the same as those in the first embodiment, and therefore, differences will be mainly described.
The ninth embodiment is obtained by replacing the page expansion process of fig. 7 in the first embodiment with the process of fig. 21.
First, when an operation for expanding a page is input by the user, the expansion direction is determined (step S5002). Here, in the case where the page size is expandable (step S5004; yes), it is determined whether the expansion operation is the first operation (step S5006). Here, in the case where the expansion operation is the first operation, the expanded page size is calculated in the first size (step S5006; YES → step S5008).
On the other hand, in the case where the expanding operation is the second operation, the expanded page size is calculated in the second size (step S5006; No → step S5012; Yes → step S5014). In the present embodiment, the other operations are performed without expanding the page (step S5006; no → step S5012; no).
Then, since the expanded page size is calculated in the first size or the second size, the page is expanded to the calculated page size (step S5010).
Here, the first operation and the second operation are switched by a method that can be easily understood by the user. For example, it can be set as:
a first operation at tap (click) and a second operation at double tap;
a first operation when tapping with one finger and a second operation when tapping with two fingers;
a first operation when tapping with one hand, and a second operation when touching and tapping with one hand;
the first operation and the second operation are assigned according to the number of inputs.
In addition, the first size may be smaller than the second size, or the first size may be larger. The first size may be set to an expanded number of pixels and the second size may be set to an enlargement ratio. In addition, the second size may also be a setting for expansion into a shaped format. For example, the operation may be an operation of automatically enlarging the size to a4 by tapping in the second operation.
[10 ] tenth embodiment ]
A tenth embodiment will be described. The above-described embodiment has been described with respect to the processing for expanding the page size, and the present embodiment is described with respect to the case where the page size is reduced by the switching operation. The functional configuration and the processing flow in the present embodiment are basically the same as those in the first embodiment, and therefore, differences will be mainly described.
The tenth embodiment is obtained by replacing a part of the main processing of fig. 6 in the first embodiment with the processing of fig. 22 (step S1020 and subsequent steps are omitted from fig. 22 for convenience of explanation).
That is, in addition to the main processing of the first embodiment, when the expand button is selected (step S1006; YES), it is determined whether or not the selection operation is the second operation (step S6002). When the selection operation is a general operation, the page expansion process is executed as in the first embodiment (step S6002; no → step S1008), and when the second operation is performed, the page reduction process is executed (step S6002; yes → step S6004).
Here, the page reduction processing performs processing of reducing the page size in the direction in which the expansion button (in this case, the reduction button) has been selected. This makes it possible to restore the enlarged page, reduce the page size, and the like.
Fig. 23 (a) shows an example of a display screen W1000 according to the present embodiment. In the expansion menu M1000 displayed on the display screen W1000, an expansion button is displayed. Here, when the expand button is touched (tapped) by two fingers as the second operation, the expand button functions as a zoom-out button. For example, the reduction processing is executed by selecting the reduction button B1000 with two fingers. In addition, as shown in the figure, the button display may be changed from "+" to "-".
Fig. 23 (b) shows a display screen W1010 in the case of the reduced page. The reduced page may also be confirmed from the display of the expansion menu M1010.
As described above, according to the present embodiment, an operation of reducing a page or the like can be performed in combination with the above-described embodiments.
Further, it may be determined from the touched position and the operation content (for example, the number of touches) that the direction is an enlargement or reduction instruction, a minus sign may be displayed when the direction is reduced, and the page may be reduced when the minus sign display is selected.
[11. eleventh embodiment ]
The eleventh embodiment will be described. The eleventh embodiment is an embodiment in which information on an expanded page is stored as history information in the above-described embodiments, and the page expansion operation is restored based on the history information.
For example, the display screen W1100 in fig. 24 shows a diagram in which the page size is expanded in the right direction after fig. 10 (a). Here, by selecting the cancel button (undo button) B1100, the expansion of the "right page" that has been currently expanded is cancelled, and the state returns to fig. 10 (a).
Further, a plurality of steps may be recovered by storing a plurality of history information. In this case, the action of expanding the menu and the action of displaying the page are to execute any of the actions of the above embodiments.
Further, in the case where a new object is configured in the middle of the page expansion operation, the object may be cancelled. In the present embodiment, the expansion menu is displayed, but may be executed integrally with a standard cancel function, for example.
[12 ] twelfth embodiment ]
A twelfth embodiment will be described. The twelfth embodiment is different from the above-described embodiments in that the expansion menu is operated to expand the page size, but the expansion menu does not display the operation button.
In the present embodiment, the main process of fig. 6 of the first embodiment is replaced with the main process of fig. 25. Here, the main process in fig. 25 is a process in which step S1006 in the main process in fig. 6 is replaced with step S7002.
That is, in the present embodiment, after the expansion menu is displayed, the expansion operation may be detected (step S7002). In the expansion menu, expansion of the page is performed by performing an expansion operation.
Here, the page expansion operation will be described with reference to fig. 26. On the display screen W1200 of fig. 26, an expansion menu M1200 is displayed. In the expansion menu M1200, a preview image is displayed, and an expansion operation of a page is detected by touching an end portion of the preview image or the outside of the preview image.
In fig. 26 (a), the outside area R1200 outside the expansion menu M1200 is touched. Thereby, the size of the right area of the page is expanded.
In the case of the display screen W1210 in fig. 26 (b), a user may perform a slide operation (a slide operation with two fingers) on the expansion menu M1210. In fig. 26 (b), since the slide operation is performed in the left direction, the right area of the page is expanded, and the page size is changed.
As described above, according to the present embodiment, even when the expansion menu does not display the expansion button in the case of expanding the page size, the expansion processing of the page size can be executed by detecting the expansion operation.
[13 ] thirteenth embodiment ]
A thirteenth embodiment will be described. The above-described embodiment has been described with respect to the case where one display device 10 is used, and the present embodiment has been described with respect to the case where the display device is executed in a multi-display environment.
As shown in fig. 27, the display device 10 and the display device 12 are arranged and displayed. That is, in the multi-display environment, the display regions displayed on the display device 10 and the display device 12 may be regarded as one or different.
When the page to be rendered is integrated by the display device 10 and the display device 12, the display area may be treated as one. In this case, the expansion menu may be displayed on any display device.
