The display apparatus 1 in
As shown in
The controller 15 may control the image processor 12 to analyze the input web page 100 and divide the web page 100 into the plurality of blocks 101 to 105. The method of dividing the web page 100 into the plurality of blocks 101 to 105 may vary. For example, the web page 100 may be divided by using a hierarchy structure of the web page 100 and by dividing the web page on an image basis.
In the “method of using the hierarchy structure of the web page 100”, a document object model tree (hereinafter, the “DOM tree”) of the web page 100 which is to be divided is obtained (process 1). Then, a block meeting the condition is extracted from the DOM tree (process 2). The condition may include the following:
(1) the extracted block is not the same in size as the block added before (removal of duplication);
(2) the block exists in a predetermined depth (a threshold value for speed up may be set, e.g., at an random value of 6 which is included in a range of 5 to 10);
(3) a width and a height of an HTML tag is a predetermined size or larger (e.g. width of 120 and a height of 30 may be set in consideration of readability and the size of a screen);
(4) only limited tags are permitted (e.g., DIV, UL, LI, DL, DD, P, TD, Table, IFRAME, TR, FORM, DT, OL, etc.);
(5) a block a depth of which is 2 or more is not out of a parent node; and
(6) a block a depth of which is 2 or more overlaps the parent node in one of top and bottom and left and right sides.
If a block which does not include other child blocks therein, among the blocks obtained through the process 1 and the process 2, is a predetermined size or larger, the concerned area only may be divided by the method of dividing the web page on an image basis (process 3). The process may be as follows:
(1) compare a color of a previous coordinate y-1 and a color of a current coordinate y by transversely scanning vertical lines of an image and a difference of a color comparison of five or more becomes a basis for dividing a previous block and other blocks;
(2) compare a color of a previous coordinate x-1 and a color of a current coordinate x by vertically scanning transverse lines of an image and a difference of a color comparison of five or more becomes a basis for dividing a previous block and other blocks;
(3) if a color is consecutive predetermined times or more in the scanning operation in the above cases, it is determined to be a line;
(4) the largest color comparison value is selected from the difference of values to R, G and B;
(5) a recursive calculation is performed based on the result of the line scanning to the transverse and vertical points to divide blocks; and
(6) the divided blocks are extracted from those not overlapping blocks extracted before.
If a tag area is not the same as the block size viewed by the human eye or if there is a white space between blocks and the divided areas are not good to view, the coordinates of the extracted blocks may be adjusted as follows (process 4):
(1) if blocks are right next to each other and a distance between coordinates of the blocks is smaller than a particular threshold value, a child block of the compared block has the same value as that of the previous block (the threshold value may be set at 50 if x components are compared, and set at 30 if y components are compared); and
(2) such coordinate comparison is performed to x and y coordinates of a left top of the block and x and y coordinates of a right bottom of the block and x is compared to x and y is compared to y, regardless of the location of the component.
If the web page is divided by the above method, any type of web page may be divided into blocks and browsed. Thus, readability of the web page information is maintained and a convenient and prompt browsing is available. As the web page can be divided into semantic blocks, the quantity of information of the web page provided to a user may be adjusted.
The block may vary in size depending on the web page 100. If the block is too large, e.g., if larger than a screen of the display unit 13, a user may find it hard to recognize the content of the block. Even if the ratio of the web page 100 is reduced to solve the foregoing problem, readability becomes worse. The block means a minimum unit of a block that cannot be divided anymore by the foregoing method.
If the block of the web page 100 is too large, the controller 15 of the display apparatus 1 according to the exemplary embodiment may redivide the block into a plurality of specific blocks for a user to recognize the content of the block.
If the focused blocks I and II according to a user's command are larger than a predetermined reference size, e.g. if the focused blocks I and II are approximately 60% or more of the screen of the display unit 13, the image processor 12 may process the web page 100 to display the focused block I in a central area of the display unit 13 (refer to
As shown in
The image processor 12 may enlarge and display the focused block II in the central area of the display unit 13 upon selection of the focused block II by a user, regardless of the size of the focused block II.
Upon receiving the scroll signal, the image processor 12 scrolls the web page 100 by block. If the web page 100 is scrolled by block, the web page 100 is scrolled according to the size of the blocks instead of a fixed moving distance, and the movement of the web page 100 becomes faster and the entire block is displayed on the display unit 13. Thus, the block is not cut or a content including the block is not cut. Also, the focused block according to a user's command may be displayed in an optimum location, and a user may quickly search the blocks.
After moving the blocks 101 according to a user's command, the image processor 12 processes the web page 100 to display the focused block I in the central area of the display unit 13 if the focused block I is larger than a predetermined size as in
After moving the block 101 according to a scroll signal, the image processor 12 determines whether the focused block II is a predetermined size or larger, e.g., 60% or more. If the focused block II is less than the reference size after the scroll operation, the image processor 12 displays the entire block II in an upper fringe of the display unit 13, and displays the predetermined dummy UI III in at least one circumference of the focused block II.
The GUI such as a frame or a thick line highlighting the focused block II may be omitted according to a user's setting.
First, the web page information is received through the input unit 11 (S10).
The controller 15 controls the image processor 12 to divide the web page 100 into at least one block 101, and displays the web page 100 in the divided blocks 101 (S20).
Upon receiving a user's command, i.e., a scroll signal to scroll the web page 100 (S30), the controller 15 moves the blocks 101 according to the scroll signal (S40).
After the movement is completed, the controller 15 determines whether the focused blocks I and II are the predetermined reference size or larger (S50).
If it is determined that the focused blocks I and II are the predetermined reference size or larger, the image processor 12 displays the focused block I in the central area of the display unit 13 (S60).
If the focused blocks I and II are less than the predetermined reference size, the image processor 12 may display the focused block II in the fringe of the display unit 13 and displays the dummy UI III in at least one circumference of the focused block II (S70). When a user performs the scroll operation, the focus is usually given to the fringe of the display unit 13 in the direction of the scroll. Thus, the focused block II which is displayed in the fringe of the display unit 13 is provided as an example, but the display area of the focused block II is not limited thereto and may vary.
The dummy UI III may be displayed in a fringe of the block II corresponding to the direction in which the scroll is performed, or displayed in all circumferences of the block II. The dummy UI III may also be displayed in a fringe corresponding to the movable direction of the block II by the scroll operation.
If the blocks I and II are focused by a user's command such as the scroll operation, the image processor 12 may display the GUI to distinguish the focused blocks I and II from other blocks.
The present embodiments are characterized by browsing the web page 100 in blocks, displaying the web page in blocks on the display unit 13, and in particular scrolling the web page 100 in blocks according to the scroll signal.
As described above, a display apparatus and a web page displaying method of the same according to an exemplary embodiment easily searches a web page.
A display apparatus and a web page displaying method of the same according to another exemplary embodiment displays a web page in blocks which are not cut or hidden.
A display apparatus and a web page displaying method of the same according to another exemplary embodiment changes a display location of a block depending on a size of the block.
Although a few exemplary embodiments have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these exemplary embodiments without departing from the principles and spirit of the invention, the range of which is defined in the appended claims and their equivalents.
