WEB BROWSING SYSTEM FOR SAVING IMAGE CORRESPONDING A MARKUP PAGE AND CONTROL METHOD THEREOF}

The present invention relates to a web browsing system for storing an image corresponding to a markup page and a control method thereof, and more particularly to a web viewer for storing at least a portion of an image form markup page received from a web viewer server. It relates to a web browsing system and a control method thereof.

Due to the development of mobile communication technology, various functions have been added to mobile communication terminals such as mobile phones. Among them, web browsing is especially used by users.

Web browsing refers to viewing / using certain web contents from a web server of an internet network using a web browser provided in a mobile communication terminal.

In general, the web server of the internet network has been configured to be accessible by using a personal computer provided in the wired internet network. Recently, due to the development of mobile communication technology, the web server access function is realized through the wireless communication network in the mobile communication terminal. As a result, the mobile communication terminal user can browse the web using his mobile communication terminal.

As such, for web browsing, a web browser for web browsing should be provided in a mobile communication terminal.

Although there are various types of web browsers, a web viewer type web browser has been proposed in order to consider hardware performance of a mobile communication terminal and to implement fast web browsing.

A web viewer is an image processing based browser, which collectively refers to a browser that simplifies the function of displaying a web page in the form of an image instead of parsing / rendering a markup tag for web browsing.

That is, a web viewer server for converting the web content of the web server into an image form is provided between the web viewer and the web server, and the web viewer uses a predetermined address, for example, a URL (Uniform Resource Locator) to When requesting the transmission, the web viewer server requests the transmission of the web content from the web server corresponding to the corresponding URL, receives the web content, parses and renders the received web content, converts the image data to the web viewer, and sends it to the web viewer. The viewer displays the web content in the form of the received image on the display unit.

Here, the web content includes all the components included in the web page, as well as a markup page written in a markup language, as well as an image file, a JavaScript file, and a style sheet file including a path to the markup page. , Multimedia files and so on. That is, all of the elements included in the web page that the user checks through the display unit when browsing the web may be referred to as web content.

As such, the web viewer of the mobile communication terminal interprets the markup tag of the markup language such as HTML (Hyper Text Markup Language) included in the web content such as a web page by itself, unlike the browser of a personal computer. Instead of rendering and displaying the web page on the display, the web page that has already been parsed / rendered by the web viewer server and then converted into an image form can be displayed. Not only that, it also has the advantage of being able to process web pages faster.

However, the image corresponding to the web page received by the conventional web viewer is transmitted in a relatively reduced state in consideration of the communication amount and transmission speed in the wireless communication section, so that the web viewer user of the web page in the form of an image If you store a certain portion of the image quality is falling is a user complaints.

For example, if a web viewer user wants to save a specific picture included in an image-type web page, the enlarged image may not be large even if the specified picture is enlarged, because the web page itself is not large in size. The quality of the image is not good, and eventually the satisfaction with the stored picture is lowered.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object thereof is to store and store at least some specific areas included in a web page in a web viewer that processes a web page in the form of an image. The present invention provides a web browsing system for storing an image corresponding to a markup page for improving the quality of a stored image and a control method thereof.

In order to achieve the above object, a web viewer for processing a markup page in the form of an image according to the present invention, a markup page providing server for providing a markup page, and a markup page received from the markup page providing server. The web browsing system including a web viewer server for capturing and converting the image into the image is transmitted by the user when the image storage command of the user is detected while displaying the image markup page on the display unit. A web viewer for transmitting an image storage request signal including selection range information corresponding to a selected range to the web viewer server and storing image data received from the web viewer server according to the image storage request signal; Selected range information is extracted from the image storage request signal received from the web viewer, and generated from the markup page captured image generated based on the markup page received from the markup page providing server and transmitted to the web viewer. And a web viewer server extracting a region corresponding to selection range information and transmitting image data of the extracted region to the web viewer.

In addition, to achieve the above object, a web viewer for processing a markup page in the form of an image according to the present invention, a markup page providing server for providing a markup page, and a markup received from the markup page providing server. In a control method of a web browsing system including a web viewer server for capturing a page, converting the image into an image, and then transmitting the image to the web viewer, the web viewer displays a markup page in the form of an image received from the web viewer server. Transmitting an image storage request signal including selection range information corresponding to a range selected on the display unit by the user to the web viewer server when an image storage command of the user is detected by the user; The web viewer server extracts selection range information from the image storage request signal received from the web viewer, captures markup pages generated based on markup pages received from the markup page providing server, and transmitted to the web viewer. Extracting an area corresponding to the extracted selection range information from an image, and transmitting image data of the extracted area to the web viewer; And storing, by the web viewer, image data received from the web viewer server.

As described above, according to the present invention, the web viewer user may store an image of an area corresponding to at least a portion of the markup page in the form of an image received and displayed from the web viewer server in the web viewer while maintaining high quality.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Web browsing system according to an embodiment of the present invention is configured to include a web viewer 100, a web viewer server 200, a markup page providing server 300 as shown in FIG.

The markup page providing server 300 is a server provided in the internet network 500 to provide a markup page including a markup tag. For example, a web server providing a web page written in HTML (HyperText Markup Language) is provided. Can be.

Here, the markup page provided by the markup page providing server 300 of the present embodiment is not created only in a specific markup language, and the type of markup language used can be variously changed.

The web viewer 100 is a kind of mobile communication terminal, and transmits a markup page request signal according to a user's command, and displays a markup page in the form of an image received from the web viewer server 200 according to the markup page request signal. Web browsing is performed by displaying on the display unit 150.

As described above, the web viewer 100 includes all terminals equipped with a web browser for web browsing such as a mobile phone and a personal digital assistant (PDA). The web viewer 100 includes a mobile communication network 400 through a base station 410. ) Can send and receive signals.

Also, when the web viewer 100 detects a user's image storage command while displaying a markup page in the form of an image received from the web viewer server 200 on the display unit 150 such as an LCD (Liquid Crystal Display) The image storage request signal including the information on the range selected by the user on the display unit 150 (hereinafter, 'selected range information') is transmitted to the web viewer server 200, and the web viewer according to the image storage request signal is transmitted. It performs a function of storing the image data received from the server 200.

An example of a function block of the web viewer 100 that performs this function is shown in FIG. 2.

As shown in the figure, the web viewer 100 includes a communication interface 110, a key inputter 130, a display 150, a storage 140, and a controller 120.

The communication interface 110 generates a communication channel with the base station 410 and performs a function of transmitting and receiving wireless communication signals with each other.

The key input unit 130 may include a plurality of key buttons (not shown) and may be configured to be operated by a user to give a predetermined command. In addition, when the web viewer 100 includes a touch screen, the key input unit 130 may perform a function of detecting an input by the touch screen and transferring the input to the control unit 120.

The storage 140 may store an application for performing various functions of the web viewer 100 and temporary data according to execution of the corresponding application. For example, the storage 140 may be configured as a flash memory.

The display unit 150 is a place where an image is displayed when the web viewer 100 performs web browsing. The display unit 150 may include an LCD having low power consumption.

The controller 120 processes the markup page in the form of an image received through the communication interface 110 to be displayed on the display 150, and interprets a predetermined command of the user through the key input unit 130. Perform the function corresponding to the command.

In particular, the control unit 120 stores an image in a range specified by the user when the user issues an image storage command through the key input unit 130 while the markup page in the form of an image is displayed on the display unit 150. The image storage request signal is transmitted to the web viewer server 200.

The range specified by the user may be any one of a specific range designated by the user or an entire range displayed on the display unit 150 among the markup pages in the form of an image displayed on the display unit 150.

For example, when the user sets a quadrangular range using a key button among markup pages of an image form displayed on the display unit 150, the quadrangular range set by the user corresponds to the specific range. If the specific range is not set by the user, the entire range currently displayed on the display unit 150 corresponds to the specific range.

When the specific range is determined as described above, the controller 120 extracts the coordinate value corresponding to the specific range, and includes the extracted coordinate value as the selection range information in the image storage request signal to the web viewer server 200. Can be sent to.

Here, the selection range information, that is, the coordinate values may be four coordinate values corresponding to the image area currently displayed on the display unit 150 of the markup page captured image received from the web viewer server 200.

That is, the selection range information is information informing the web viewer server 200 of which part of the markup page capture image received by the web viewer 100 is to be stored. The web viewer server 200 will be described later. Uses the selection range information to specify a predetermined range on the markup page captured image that the user wishes to store.

Meanwhile, when the markup page request signal is received from the web viewer 100, the web viewer server 200 requests the markup page from the markup page providing server 300, receives the markup page, and interprets the received markup page. To create.

The process of interpreting the markup page as an image may be performed by parsing and rendering the markup page to be displayed on a predetermined display device and capturing the displayed screen.

The web viewer server 200 transmits the markup page of the generated image form to the web viewer 100. At this time, the web viewer server 200 does not transmit the captured image itself, but transmits the web page captured image to the web viewer 100 having a greatly reduced capacity in consideration of the communication speed and the supported resolution of the web viewer 100. .

In addition, when the image storage request signal is received from the markup page providing server 300, the web viewer server 200 extracts selection range information from the image storage request signal, and extracts the selection range information extracted from the markup page captured image. Extracts an area corresponding to and transmits the image data of the extracted area to the web viewer 100.

An example of a functional block of the web viewer server 200 that performs this function is illustrated in FIG. 3.

As shown in the figure, the web viewer server 200 includes a communication interface 210, a storage 220, a communication processor 240, a specific region extractor 260, a markup page interpreter 230, The image generator 250 and the data transmitter 270 are configured to be included.

The communication interface 210 is configured for communication with an external network, and in particular, a web viewer 100 interworking with the mobile communication network 400 and an internet network 500 connected through the mobile communication network 400 and the router 510. Communication with the markup page providing server 300 of FIG.

The storage unit 220 temporarily or fixedly stores data generated while performing an application and a function for the function of the web viewer server 200.

Since the communication interface 210 and the storage 220 correspond to a known configuration, a detailed description thereof will be omitted.

The communication processor 240 determines which function should be performed according to the communication signal received through the communication interface unit 210 and transmits the corresponding signal (request or message) to each corresponding part. For example, when a markup page is received from the markup page providing server 300, the markup page is transmitted to the markup page interpreter 230, and when an image storage request signal is received from the web viewer 100. The request signal is transmitted to the specific region extraction unit 260.

The markup page analyzer 230 interprets the markup page received from the markup page providing server 300. Parsing the markup page here includes parsing and / or rendering the markup page.

The image generator 250 outputs the markup page parsed and rendered by the markup page analyzer 230 to a predetermined display device, captures a screen, generates an image file, and then transfers the data to the data transfer unit 270. To pass on.

Of course, the method of generating the image corresponding to the markup page by the image generator 250 is not limited thereto. For example, it may be performed by an operation in a memory without outputting to an actual display device.

The image generator 250 may undergo an image conversion process of reducing the capacity to increase the resolution and transmission efficiency of the web viewer 100 before transferring the generated image (or image file) to the data transmitter 270.

The specific region extractor 260 extracts selection range information from the image storage request signal received from the web viewer 100, and extracts the selection range information from the markup page capture image generated by the image generator 250. It extracts a corresponding region and delivers the image (ie image data) of the extracted region to the data transmitter 270.

The data transmitter 270 transmits the image generated by the image generator 250 or the image extracted by the specific region extractor 260 to the web viewer 100 through the communication interface 210. To perform.

Here, the image generated by the image generator 250 corresponds to an image captured by the entire markup page, and the image extracted by the specific region extraction unit 260 is a mark made according to a request of the user of the web viewer 100. The image corresponds to at least a portion of the entire up page captured image.

The data transmitter 270 may transmit both the image generated by the image generator 250 and the image generated by the specific region extractor 260 to the web viewer 100 using the same protocol. The entire captured image of the markup page generated by the unit 250 is transmitted by a TCP / IP (Transmission Control Protocol / Internet Protocol) communication method, and MMS (image) generated by the specific region extraction unit 260 is used. The web message may be delivered to the web viewer 100 through a multimedia message service.

Hereinafter, a control flow of a web browsing system according to an embodiment of the present invention will be described in detail with reference to FIG. 4.

First, when the web viewer 100 detects a user's markup page request command, the web viewer 100 transmits a markup page request signal to the web viewer server 200 (step S1). In this case, the markup page request signal may include an address of a requesting markup page, for example, a Uniform Resource Locator (URL).

The web viewer server 200 requests a markup page from the markup page providing server 300 according to a request of the web viewer 100 (step S3). In this case, the URL of the markup page may also be used.

The markup page providing server 300 extracts the requested markup page based on the URL and transmits the markup page to the web viewer server 200 (step S5).

The web viewer server 200 interprets the markup page received from the markup page providing server 300 (step S7) and generates an image corresponding to the markup page (step S9). An example of a markup page received from the markup page providing server 300 is illustrated in FIG. 5.

5 shows a state where the markup page is parsed and rendered and displayed on the display unit 150 or the like. That is, the web viewer server 200 captures a screen as shown in FIG. 5 and generates an image.

Using the generated image, the web viewer server 200 converts the image size to an appropriate size in consideration of the resolution of the web viewer 100 and the transmission efficiency through the wireless communication section (step S11). In other words, the converted image may be slightly reduced in image quality compared to the original captured image.

The markup page in the form of the final converted image is transmitted to the web viewer server 200 (step S13), and the web viewer 100 processes the received image and displays it on the display unit 150 (step S15).

An example of displaying a markup page in the form of an image on the display unit 150 of the web viewer 100 is illustrated in FIG. 6.

As such, the markup page displayed in the web viewer 100 is only an image form and can be displayed even if the markup page interpretation process such as parsing is not performed in the web viewer 100.

The web viewer 100 enlarges or reduces the image markup page displayed on the display unit 150 (step S19) according to the operation of the user's zoom in / out function (i.e., zoom in / zoom out function) (step S17). It can also be viewed by the user.

7 illustrates an enlarged state of the screen displayed on the display unit 150 of the web viewer 100. As described above, the markup page capture image data received from the web viewer server 200 is small in size and thus enlarged. As shown in Fig. 7, the image is not clear. In other words, only the image of low quality is stored when the image in the enlarged state is recaptured and stored in the web viewer 100 itself.

When the user's image storage command is detected while zooming in a specific image area (step S21), the web viewer 100 extracts the coordinates of the image currently displayed on the display unit 150 of the entire markup page captured image. (Step S23).

That is, as shown in FIG. 7, the entire range displayed on the display unit 150 may be coordinate values (for example, an angle corresponding to a quadrilateral) that may specify a position in the entire markup page captured image illustrated in FIG. 6. Vertex coordinate value).

The web viewer 100 transmits an image storage request signal including the extracted coordinate value to the web viewer server 200 (step S25).

The web viewer server 200 extracts an image of a portion corresponding to a specific coordinate value included in the image storage request signal from the markup page capture image generated in step S9 (step S27). For example, as shown in FIG. 8, a predetermined range may be specified using four coordinate values included in the image storage request signal to extract an image of a corresponding portion.

In this case, for a specific range of images extracted by the web viewer server 200, even if the conversion process such as step S11 is omitted or converted, the image quality is reduced as much as possible by reducing the image capacity less than the conversion process in step S11. Should be avoided. Thus, user satisfaction with the image quality of the image stored in the web viewer 100 may be increased.

The web viewer server 200 transmits the extracted specific range image to the web viewer 100 (step S29). In this case, the web viewer server 200 may transmit the specific range image to the web viewer 100 by any one of the TCP / IP method and the MMS method.

The web viewer 100 stores an image of a specific range received from the web viewer server 200 (step S31).

When the web viewer 100 detects a pre-stored image viewing request from the user through a menu as shown in FIG. 9 (step S33), the web viewer 100 displays the requested image as shown in FIG. 10 (step S35), and as a result, the markup page capture image. The user can save some of the images for later viewing.

It can be seen that the quality of the image shown in FIG. 10 is different from the quality of the image shown in FIG. 7.

In the above-described embodiment, four coordinate values are transmitted from the web viewer 100 to the web viewer server 200 as selection range information. However, it is necessary to specify an area selected by the user in the entire markup page captured image. Anything you can do is possible.

For example, the web viewer 100 transmits the coordinate value of the center position of the area currently displayed on the display unit 150 to the web viewer server 200, and the web viewer server 200 refers to the center coordinate value. As such, a specific range of images corresponding to the size considering the screen size of the web viewer 100 may be extracted from the entire markup page captured image and transmitted to the web viewer 100.

On the other hand, the present invention is not limited to the above specific embodiments, but can be modified and modified in various ways without departing from the gist of the present invention. It will be apparent that such variations and modifications are included in the present invention as long as they belong to the appended claims.
