FIG. 2 is a view showing a control flowchart when creating / editing a table type document according to the present invention. FIG.

Prior to the description with reference to FIG. 2, it is assumed that the flow chart of FIG. 2 is performed in the smartphone assumed above. However, it is not necessarily a smart phone, and a portable mobile terminal capable of creating / editing documents on a tablet computer or the like is sufficient.

In the present invention, a table type document corresponds to a document including an Excel document, a Hangul character or a table in MS-WORD. However, for convenience of description, the present invention describes the present invention based on an Excel document.

Also, in the present invention, the application program may be provided as a single software or as a small application operating on a smart phone. And can select an application to be driven in advance when it is driven by a separate application. For example, when the Excel is driven, it can be selected by selecting to drive the enlarged application according to the present invention, or by selecting the expanded application to be driven when Excel, Hangul and Word documents are driven. This will be described in detail with reference to FIG.

Referring to FIG. 2, it can be seen that the control flowchart is performed in the document operation mode. The document operation mode is a state in which a specific document is selected in the mobile terminal 100 and display of the selected document is requested. That is, the application for displaying the selected document is being driven by the mobile terminal 100.

In this state, the control unit 105 reads the application corresponding to the document selected in step S200 from the memory 107, drives the application, reads the selected document data from the memory 107, On the display unit 109 in the form of an image. When the displayed document is a Hangul file, a word file, or an excel file, the corresponding application is driven and the document data is displayed on the display unit 109 through the application. An example in which an Excel document is selected and displayed is illustrated in FIG.

3 is a diagram illustrating a format in which a specific cell is selected when an Excel document is edited in the mobile terminal 100. In FIG.

3, reference numeral 300 denotes an area for displaying the mobile communication function and the battery status of the mobile terminal 100. Reference numeral 302 denotes a setting for controlling the creation / And reference numeral 304 denotes an area for displaying a value of a specific cell selected by the user. Reference numeral 306 denotes an area for loading and displaying an Excel document, and a cell selected by the user is specifically denoted by reference numeral 310. Reference numeral 308 denotes a keyboard region for user input.

As shown in FIG. 3, in a state in which the Excel document is displayed, the control unit 105 proceeds to step S202 to check whether display movement is requested. This display movement means a case where there is a page movement input signal such as a movement through a screen scroll bar operation displayed on the display unit 109 or a page up / down. The control unit 105 checks whether a page movement is requested by the user through the touch input unit 111 or the key input unit 115. [

If it is determined in step S202 that the page display movement is requested by the user, the control unit 105 proceeds to step S210, and if not, proceeds to step S204.

When the process proceeds to step S210, the control unit 105 moves the display area corresponding to the user's selection. For example, if page up is requested, the previous data of the currently displayed data in the Excel document is read from the memory 107 and displayed on the display unit 109. [ On the other hand, if page down is requested, the subsequent data of the currently displayed data in the Excel document is read from the memory 107 and displayed on the display unit 109.

When the user requests to scroll the page using the scroll bar displayed on the display unit 109, that is, when scrolling is requested from the touch input unit 111, the control unit 105 controls the memory 107 And displays it on the display unit 109. The display unit 109 displays the document data on the display unit 109. [ After this display, the control section 105 proceeds to step S200 again.

On the other hand, if it is determined in step S202 that the page display movement is not requested from the user, the control unit 105 proceeds to step S204 to determine whether the user has selected a specific position or cell in the Excel document Inspect. If the specific location or cell is selected as a result of the check in step S204, the control unit 105 proceeds to step S220, otherwise proceeds to step S206.

The control unit 105 checks whether the end of the application program displaying the current document is requested from the touch input unit 111 or the key input unit 115. If the end of the application program displaying the current document is requested, If it is determined in step S206 that the end of the application program displaying the current document is requested, the document operation mode is terminated. On the other hand, if the termination of the application program is not requested, the control unit 105 proceeds to step S200 to maintain the display state of the currently selected document.

Next, the case of proceeding to step S220 of the inspection result of step S204 will be described. In step S220, the controller 105 enlarges a predetermined area around the position or cell selected by the user and displays the enlarged area on the display unit 109. [ At this time, although the selection of the corresponding area may be made by one selection, the user may inconvenience the use of the selected area. Therefore, the user may select the corresponding area more than twice within a preset time, And the selection time of the < / RTI >

That is, when a specific region is selected, if the touch is performed twice within a short time, for example, within one second, enlargement may be regarded as being requested. Alternatively, if the region is selected continuously for a predetermined period of time, for example, 1.5 seconds or more, enlargement may be regarded as being requested. In this way, it is possible to clarify whether enlargement is required by using such a method in order to prevent enlargement when the user accidentally touches.

The state before and after the enlargement and the enlargement will be described with reference to FIG. 3 and FIG. 4.

3, in the conventional technique, even when a specific area or cell is selected at the time of creation / editing of a document in the mobile terminal 100, the setting value of the area 304 or 304 You have to look through the area. Since the mobile terminal 100 is made small for carrying, the display unit 109 is also made small so that the cells selected by the user are displayed in a small size. Therefore, even if the user selects a neighboring cell other than the cell to be originally selected, the user can confirm the fact that the user himself / herself has selected the wrong cell through the area 304.

In the present invention, a method of enlarging a corresponding area is considered. Generally, the enlargement method must select a specific area in the Excel document display area 306 and then request enlargement of the area by setting a magnification through the program menu. That is, when the user requests enlargement of a part of the area displayed on the display unit 109 through the menu, the user generates an enlargement request signal for the area selected by the display unit 109 through the touch input unit 111, (105). Then, the control unit 105 calculates the area to be enlarged based on the information input from the touch input unit 111, and displays the calculated area on the display unit 109.

When the user wants to view the entire Excel document as shown in FIG. 3, the user is requested to reduce the screen display through the menu of the Excel program. Then, the touch input unit 111 scales down the screen based on the menu operation information input by the user. Also, when the user desires to continuously check the values of a particular cell and its neighboring cells, the user must request enlargement and reduction through the program menu every time.

4 is an enlarged view of a selected cell when a specific cell is selected when an Excel document is edited in the mobile terminal 100 according to the present invention.

Hereinafter, an embodiment according to the present invention will be described with reference to FIG. 4, reference numeral 300 denotes an area for displaying a mobile communication function and a battery status of the mobile terminal 100. Reference numeral 302 denotes a setting area for controlling the creation / And reference numeral 304 denotes an area for displaying a value of a specific cell selected by the user. Reference numeral 400 denotes an Excel document display area. When the user selects a specific cell, the cell is enlarged and displayed in a size convenient for viewing. Reference numeral 410 denotes a case where one cell is selected in the Excel document. Reference numeral 308 denotes a keyboard region for user input.

In the initial state, that is, in step S200, a document is displayed as in the above-described [FIG. 3]. At this time, when the process proceeds from step S204 to step S220, the control unit 105 enlarges the selected area or cell to a size convenient for the user to display, including the certain adjacent area of the selected cell, on the screen. At this time, the enlarged size may be different for each user. For example, the younger age group is at least part of the expansion because it has a good visual acuity. However, the elderly should not be able to see small prints, so the expansion rate should be higher than the younger age group. Therefore, the enlargement ratio can be preset by the user.

For example, for younger age groups, if the original ratio is assumed to be 1, and if it is expanded to twice the size, it is preferable to enlarge the elderly group to 3 times or 4 times. Therefore, the magnification can be stored in advance according to the visual acuity of the user.

In addition, the user may set the size of a letter, a number, a symbol, or the like of a desired size in advance, and automatically adjust the magnification so that the size currently displayed is a predetermined size. For example, if the currently displayed size is 1/2 of the size preset by the user, the magnification is set to be doubled. If the displayed size is 1/3 of the size preset by the user, As shown in FIG.

Accordingly, when the process proceeds to step S220, the control unit 105 enlarges and displays the selected position with a predetermined magnification or a predetermined size with respect to the selected position or the selected cell, such that a letter, number, or symbol has a predetermined size.

Although FIGS. 3 and 4 illustrate an Excel document as an example, in the case where a table is displayed in a document such as Hangul or a word, the neighboring region of the selected position can be enlarged in the same manner.

In the example of FIG. 4, the entire screen of the Excel document is shown in an enlarged form while the vicinity of the selected cell is centered on the screen. However, it is also possible to implement such that only the area near the inputting or updating position of the user is concentrated rather than the entire screen. That is, other regions may be displayed as shown in FIG. 3 and only the enlarged portion may be selectively displayed as shown in FIG.

Thereafter, the control unit proceeds to step S222 to check whether the user performs an operation to move the cell. If there is a cell movement operation, the control unit moves the cell in the Excel document and adjusts the enlarged display around the moved position S224).

Then, the control unit 105 proceeds to step S226 to update the value of the corresponding cell according to information received from the touch input unit 111, that is, information input by the user. That is, in the [Figure 3] and [Figure 4], the value of the corresponding area is updated in correspondence with the value input by the user in the keyboard region 308 for the user's input. While the cell value is being updated, the control unit 105 keeps the enlarged state around the area where the update is performed as shown in FIG. 4, and displays the enlarged state on the display unit 109.

When the data update of the selected cell is performed as described above, the control unit 105 proceeds to step S228 to return the display format of the Excel document to the non-enlarged screen, that is, the standard screen as shown in FIG. A special key for returning to the screen may be input or a separate icon (not shown in [Figure 3] and [Figure 4]) may be selected for returning to the screen on the display unit 109. [ When the non-enlarged screen is returned to the non-enlarged screen, the controller 105 proceeds to step S200 and maintains the display in the state of FIG. 3 as described above.

FIGS. 5 to 7 are views showing another embodiment for expressing the technical idea of the present invention. FIG.

FIG. 5 is a view showing a state in which the rightmost cell 320 is selected in the Excel document, FIG. 6 is a view showing a state in which a screen enlargement form is determined adaptively according to the position of the selected cell 320 . That is, in the present invention, the enlarged selection cell display 420 is displayed on the center of the display screen 109 by enlarging (420) the center of the cell 320 selected by the user.

On the other hand, in the embodiment of FIG. 6, there is a problem that meaningless contents are displayed on the right side of the enlarged cell 420. As described above, it is preferable that the mobile terminal 100 is implemented in such a manner that there is no waste because the display area is narrow. In FIG. 7, as the selected region 320 recognizes that the selected cell 320 is a critical region of the effective cell, the enlarged selected cell 420 is arranged in a critical region other than the center of the display screen. Thereby effectively utilizing the display area of the mobile terminal 100.
