First embodiment

Recently, as the processor of the mobile terminal, i.e., the controller 180, improves dramatically, advanced computation is possible. In addition, the performance of the wireless communication unit 110 has been improved to enable high-speed data communication through various air interfaces. This enables the same level of Internet surfing, or web browsing, as a desktop computer environment on a mobile terminal. However, since a web page is generally designed in consideration of a desktop environment, a mobile terminal having a display unit 151 having a smaller size than a desktop environment frequently scrolls or displays the web page area displayed on the display unit 151. You should zoom in on. In other words, if the display magnification is large, information / links appearing on one screen may be insufficient. If the display magnification is small, visibility or difficulty in link selection may be difficult due to too many information or links appearing on one screen. This will be described with reference to FIG.

Referring first to (a) of FIG. 4, the number of links displayed in one screen is excessively large, and the area occupied by each link is small, making it difficult for the user to accurately select and reducing the readability of the text. It is necessary to increase (ie enlarge). In addition, in the situation as shown in FIG. 4B, the number of links is too small, so that the information displayed at one time is too small and the display magnification needs to be reduced (ie, reduced).

Accordingly, an embodiment of the present invention proposes a method for optimizing the display magnification of a web page displayed according to a predetermined criterion by using information included in the web page. This will be described with reference to FIG.

5 illustrates an example of a process of determining an optimal magnification according to an embodiment of the present invention.

Referring to FIG. 5, first, the controller 180 displays information of a web page according to a web address input by a user in a web page, a selection of a link or a bookmark, or a web browser address set as a default as a web browser is executed. The control may be performed to download the included document, and the optimal magnification may be determined using at least some of the information included in the document (S501).

In this case, the document including the information of the web page is written in a predetermined web programming language, the web programming language is a concept including all of the hypertext markup language (HTML), Java (Java), XML, CSS, ASP, etc. . For convenience, the following web programming language is assumed to be HTML. In the end, the document is considered to be an HTML document.

Information for determining the magnification is as follows.

-Number of links: Links generally have the form of a string with an underscore, but the link according to the present invention is not limited to this form, and includes a link in the form of an image, a link in the form of a flash, and the like.

-Number of strings: The number of strings is preferably set for each font size.

Number of images: The number of images is also preferably set for each image size.

Presence of Tables: If there are tables that classify areas on the web page by HTML tags, the number, size, etc. of the tables may be considered.

-Presence or absence of a preset magnification may be taken into account for web page specific (ie, address-by-address).

At this time, the analysis process of the HTML document to obtain information for determining the optimal magnification may follow the following procedure.

Convert the downloaded HTML document into a Well-Formed document (i.e. grammar check and correction or XML document)

-Recognize each tag in the document

Parsing into a tree structure based on recognized tags

-Read tree information from top to bottom to grasp the information contained in each tag

-Analyze hyperlink tags, image link tags, and string output tags in documents

After obtaining the information for determining the optimum magnification through the above-described process, the controller 180 may determine the optimum magnification for displaying the initial screen by using the analysis result and the preset optimal magnification determination condition.

For example, when the optimal magnification determination condition is set to 'the number of links displayed on the screen = 10', the controller 180 may determine an enlarged magnification such that 10 links are included in the initial screen as the optimum magnification. That is, determining the optimal magnification may mean determining a range of an area displayed on one screen of a web page. In this case, the reference point of the magnification adjustment may be the center of the screen or the upper left, but this may be changed according to the user's setting.

Thereafter, the controller may display the web page scaled according to the determined optimal display magnification (or display area) on the display unit (S503).

However, if the function for providing the optimum magnification is set not to be applied to the initial screen (S502), the web page is displayed at the magnification set by default in the web browser (511), and the optimal magnification display command by the user is performed later. If it is input (S512), the optimal magnification display function according to the present embodiment may be performed. In this case, the controller 180 may control the function to be performed by adjusting the display magnification so as to satisfy the optimum magnification determination condition in the webpage area displayed at the time of input of the command.

At this time, the optimal magnification display command by the user is specific to the sensing unit 140 that detects the shaking of the mobile terminal or the manipulation of a specific hardware key button provided on the mobile terminal body, the manipulation of a specific virtual key button displayed on the touch screen. The method may be performed by a method of detecting a shake of a pattern.

Hereinafter, a result of performing the optimal magnification display method according to the present embodiment will be described with reference to FIGS. 6 and 7.

6 illustrates an example of a form in which a webpage scaled to satisfy an optimum magnification determination condition is displayed according to an embodiment of the present invention.

In FIG. 6, it is assumed that the optimal magnification determination condition is set to the number range of links.

First, on the left side of FIG. 6A, an arbitrary web page according to a default magnification setting of a web browser is displayed. In the form where the left web page is displayed, too many links are included. In this case, when the optimal magnification adjustment according to the present embodiment is performed, the display magnification may be increased such that the number of links displayed on one screen is within a range that satisfies the optimal magnification determination condition as shown on the right side.

In addition, on the left side of FIG. 6B, another arbitrary web page according to the default magnification setting of the web browser is displayed. In the form where the left web page is displayed, too few links are included. In this case, when the optimal magnification adjustment according to the present embodiment is performed, the display magnification may be lowered such that the number of links displayed on one screen is within a range satisfying the optimum magnification determination condition as shown on the right side.

7 illustrates another example of a form in which a webpage scaled to satisfy an optimal magnification determination condition is displayed according to an embodiment of the present invention.

In FIG. 7A, it is assumed that the optimum magnification determination condition is set to the number range of a string (string). First, the left side of (a) of FIG. 7 is a form in which an arbitrary web page is displayed according to the default magnification setting of the web browser. Too many strings are included in the form in which the left web page is displayed. At this time, when the optimal magnification adjustment according to the present embodiment is performed, the display magnification may be increased such that the number of character strings displayed on one screen is within a range that satisfies the optimal magnification determination condition (that is, 710 regions are displayed) as shown on the right. Can be.

In FIG. 7B, it is assumed that the optimal magnification determination condition is set to the number range of images (for example, two). On the left side of FIG. 7B, an arbitrary web page according to a default magnification setting of the web browser is displayed. In the form where the left web page is displayed, too many images are included. In this case, when the optimal magnification adjustment according to the present embodiment is performed, the display magnification may be increased such that the number of images displayed on one screen is within a range that satisfies the optimal magnification determination condition as shown on the right side.

Although it has been described in the above-described embodiment that only one element is considered at a time as an optimal magnification determining condition, this is exemplary and may be considered when two or more elements simultaneously determine an optimum magnification. For example, the number of images and the number of links may be set as optimum magnification determination conditions at the same time. In such a case, it is preferable that a condition to be considered first is set when it is difficult to find a magnification that satisfies both conditions simultaneously.

Second Embodiment

According to another embodiment of the present invention, even when an area displayed on the display unit is changed as a user inputs a command for scrolling a web page, an optimal magnification for the changed area may be provided. This will be described with reference to FIG. 8.

8 illustrates an example of determining an optimal magnification when a display area of a web page is changed by screen scrolling according to another exemplary embodiment of the present invention.

Referring to FIG. 8, first, a predetermined area of a web page may be displayed at a web page display magnification set as a default in a web browser or at an optimum magnification according to an embodiment of the present invention (S801).

At this time, it is assumed that the analysis of the HTML document of the web page for obtaining the information for determining the optimal magnification according to the process S501 of FIG. 5 is performed in advance by the controller.

Subsequently, when the area displayed on the display is changed as the user inputs a command for changing (eg, scrolling) the display area of the web page (S802), the controller 180 determines a preset optimal magnification condition. In operation S803, an optimal display magnification of the changed area may be determined to satisfy the condition.

Thereafter, the area changed according to the determined optimal display magnification may be adjusted and displayed on the display unit (S804).

An example of the mode in which the optimum magnification of the display area changed by the scroll according to another embodiment of the present invention is displayed will be described with reference to FIG. 9.

In FIG. 9, it is assumed that an optimal magnification determination condition is a number range of links (for example, 10 to 15) displayed on one screen.

First, referring to FIG. 9A, a web page area adjusted according to a default setting or adjusted to an optimal magnification is displayed.

In this case, as the user changes the webpage area displayed through the manipulation of a navigation key or a touch input of a predetermined pattern, an area as shown in FIG. 9B may be displayed on the webpage. The region shown in FIG. 9 does not satisfy the optimal magnification determination condition including only two links. Accordingly, the optimal display magnification change according to the present embodiment is performed, and as a result, the display magnification can be reduced so as to satisfy the optimum magnification determination condition as shown in FIG. 9C, so that an appropriate number of links can be displayed.

Third Embodiment

According to still another embodiment of the present invention, when a user inputs a command for changing a displayed web page area, a method of determining and displaying a magnification and a position of a web page existing in a direction of a corresponding change command in advance is provided. .

For example, when a scroll command is input in one direction to change the displayed web page area, the scroll range may be automatically determined to satisfy the optimal magnification / positioning condition of the web page area existing in the scroll direction. have. That is, before displaying the web page existing in the direction corresponding to the scroll command, the magnification and position to be displayed in advance may be determined and immediately changed to a screen satisfying an optimal magnification / positioning condition located in the scroll direction. More specifically, for example, when an optimal magnification / positioning condition is that three links are included in one screen, a web page area in which three links located in the scrolling direction enter at once may be displayed immediately.

This will be described with reference to FIG. 10.

10 shows an example of an optimal display magnification and display positioning process according to another embodiment of the present invention.

First, since step S1001 of FIG. 10 is similar to step S801 of FIG. 8, redundant description will be omitted for simplicity of the specification.

Thereafter, a command for changing the display area may be input from the user (S1002).

Examples of such a command may include input of a navigation key corresponding to a specific direction or input of a touch pattern corresponding to a scroll command for a specific direction.

When a command for changing the display area is input, the controller 180 determines information for determining an optimal magnification of a web page existing in a direction corresponding to the command, and a magnification that satisfies a preset optimal magnification / positioning condition. And the position can be determined (S1003).

That is, the controller 180 may determine a web page area that satisfies an optimal magnification / positioning condition among web page areas existing in a direction corresponding to the command. At this time,

Thereafter, the web page existing in the direction corresponding to the command may be displayed according to the determined magnification and position (S1004).

On the other hand, if the position / magnification was automatically adjusted before the display area was changed, the previously adjusted magnification may be maintained regardless of scrolling when the display area is changed again later. The magnification may be newly adjusted according to conditions such as a link / image / string to be included in the screen to be displayed on the screen.

Hereinafter, a detailed form of the display area change command will be described with reference to FIG. 11.

11 is a view for explaining an example of a command input method for changing a display area of a web page according to another embodiment of the present invention.

In order to receive a command for changing the display area from the user, as illustrated in FIG. 11A, the scroll bar area 1110 may be displayed in one area of the display unit 151. In this case, the optimal magnification / positioning condition may be displayed on the scroll bar 1120. In this case, as the user lowers or raises the scroll bar, a web page area that satisfies an optimal magnification / positioning condition located in the corresponding direction may be displayed.

Alternatively, the navigation key region 1130 may be displayed as shown in FIG. 11B. The optimum magnification / positioning condition may also be displayed in the navigation key area.

Instead of displaying a separate scroll bar area or a navigation key area, a web page area displayed through dragging or flicking touch input for scrolling may be changed as shown in FIG.

On the other hand, the optimum magnification / positioning condition according to the present embodiment is different from the optimum magnification determination conditions of the first and second embodiments of the present invention, and the position is further considered. An example of the positioning method according to the present embodiment will be described with reference to FIG.

12 is a view for explaining an example of the display position determining method according to another embodiment of the present invention.

In order to determine the optimal display position according to the present exemplary embodiment, the existence of a table, whether or not a preset string is included / included, the presence or absence of an area (offset, etc.) preset as a web page, and scrolling in case of triggering according to page scrolling The presence or absence of the above-described conditions (including magnification determining conditions) present in the direction (i.e., the region to be displayed next) may be considered.

In the web page shown in FIG. 12A, the upper left area 1200 may be initially displayed according to the default magnification setting of the web browser.

In this case, when the web page specific region 1210 is set in advance, when a command for changing the display region is input from the user, an optimal display magnification may be determined in the specific region 1210 as shown in FIG.

Alternatively, when the priority of positioning is given to the character string "Top News", when the display area change command is input from the user, the optimal display magnification may be determined in the table including the character string as shown in FIG. have.

13 shows an example of a specific form in which a display magnification and a display position are determined according to another embodiment of the present invention.

In FIG. 13, it is assumed that the number of links is set to an optimal magnification / positioning condition.

FIG. 13A illustrates a line in which a link included on an arbitrary web page 1310 is disposed.

According to an initial setting of a web browser or an optimal display magnification of an initial display area according to an embodiment of the present invention is applied, an area initially displayed is assumed to be 1320 area.

In this case, when the user inputs a command to scroll downward, if the display of the optimal magnification / position adjusted webpage area according to the present embodiment is not performed, the area 1330 will be displayed.

However, when the optimal magnification / position adjusted webpage area display according to the present embodiment is performed, the area 1340 may be immediately displayed as the user inputs a command to scroll downward. As a result, as shown in (b) of FIG. 13, instead of passing through all of the processes (a) to (c) of FIG. 9, only the scroll command input in one direction is used in FIGS. 9 (a) to 9 (c). The corresponding web page area can be displayed immediately.

On the other hand, in another aspect of the present embodiment, when all of some links / images / strings, etc. are not displayed in the currently displayed web page area, the user performs an operation related to scrolling in a direction in which a part which is not displayed exists ( Navigation key manipulation, dragging, flicking, etc.) may be scrolled to the extent that all the non-displayed parts are displayed.

In addition, in the above-described embodiments, the execution of the optimal magnification / position display may be triggered when the user moves to a new page through a link, when the user moves to a new page and then returns to the previous page.

In addition, in the above-described embodiments, even if the entire link / image / string is not displayed on the screen according to the adjusted magnification / position, only the optimal magnification / positioning condition described above may be displayed, and the link / image / string may be displayed. The position / magnification can be further adjusted so that the entire string can be displayed on the screen. The limit of the magnification is preferably set in advance, and a plurality of settings may be prepared according to conditions such as web page specification, area specification, or presence or absence of a table.

Further, according to an embodiment of the present invention, the above-described method can be implemented as a code that can be read by a processor on a medium on which the program is recorded. Examples of processor-readable media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and may be implemented in the form of a carrier wave (for example, transmission over the Internet). Include.

The mobile terminal described above can be applied to not only the configuration and method of the embodiments described above but also all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments It is possible.
