For example, the server device 10 of a desired website is accessed to acquire the web content 15a and meta information (RSS) 15b, and the layout is easy to handle based on the meta information (RSS) 15b. Displayed as a web page or printed.

  FIG. 2 is a block diagram showing a circuit configuration of the server apparatus 10 in the server / client system.

  The server device 10 includes a CPU 11 as a computer, and an external storage device 15 such as a ROM 13, a RAM 14, and an external hard disk is connected to the CPU 11 via a bus 12.

  Further, an input device 16 such as a keyboard and a mouse, a display device 17 such as an LCD (Liquid Crystal Display), and a communication I / F (interface) 18 with the client devices 20 are connected to the CPU 11 via the bus 12. The

  The CPU 11 controls the operation of each part of the circuit by using the RAM 14 as a working memory in accordance with a system program or various application programs stored in advance in the ROM 13, and via a key input signal from the input device 16 or a communication I / F 18. The various programs are activated and executed in response to a Web content acquisition request signal or the like corresponding to a user operation from the client device 20 received.

  The web content 15a and meta information (RSS) 15b are generated and stored in the external storage device 15, for example.

  FIG. 3 is a block diagram showing a circuit configuration of the client device 20 in the server client system.

  The client device 20 includes a CPU 21 as a computer, and a ROM 23, a RAM 24, and an external storage device 25 such as a memory card and an optical disk read / write unit are connected to the CPU 21 via a bus 22.

  Further, an input device 26 such as a keyboard and a mouse, a display device 27 including an LCD, and a communication I / F (interface) 28 with the server device 10 are connected to the CPU 21 via the bus 22.

  The CPU 21 controls the operation of each part of the circuit by using the RAM 24 as a working memory in accordance with a system program and various application programs stored in advance in the ROM 23. The various application programs are executed according to input signals from the input device 27. It is activated and executed.

  When the server device 10 is a Web site on the Internet (N) and the client devices 20,... Are user terminals that can access the Web site, an access request from the user terminal (20) to the Web site (10) is made. In response, the Web content 15a described and generated in HTML on the Web site (10) is distributed to the user terminal (20) of the access request source, and is displayed on the display device 27 by being expanded into a Web page by the Web browser program 23a. Is done.

  The Web browser program 23a of the client device (user terminal) 20 acquires the Web content 15a and meta information (RSS) 15b in response to access to the server device 10 of the Web site designated by the user, and the meta information (RSS) 15b has a function of displaying as a Web page having a layout that is easy for the user to handle, and the page display function is realized by, for example, a program that plugs in or adds to the Web browser program 23a.

  That is, the client device 20 acquires the title character string of each part in the Web content 15a from the meta information (RSS) 15b acquired from the server device 10 of the specified Web site, and the title character string in the content 15a. An HTML element (title element) including Then, the content 15a is divided into blocks using the title element as a delimiter position, and display control of a layout that is easy for the user to handle is performed in units of blocks. At this time, if the update time or summary of each part in the content included in the meta information (RSS) 15b is used as display control key information, the display can be controlled with a more convenient layout.

  The content 15a developed on the web page by the web browser program 23a of the client device 20 is developed on the frame buffer FB in the RAM 24 and displayed on the display device 27. Then, with respect to the Web content 15a developed in the frame buffer FB, the division position where the title element is divided into division positions based on the meta information (RSS) 15b is managed and controlled by coordinates as display data. .

  FIG. 4 is a diagram showing a simple example of the relationship between the web content 15a acquired from the server device 10 of the designated website in the client device 20 and the meta information (RSS) 15b.

  The meta information (RSS) 15b is generally distributed in units of categories in the website or the site, and plays a cataloging role for the content 15a therein.

  For example, when meta information (RSS) 15b (see FIG. 4C) is distributed to Web content 15a as shown in FIG. 4A, as an attribute value of the <link> tag in the content 15a The URL 15ar (see FIG. 4B) of the meta information (RSS) 15b is described. The Web browser 23a sees the URL 15ar of the meta information (RSS) 15b and knows that the meta information (RSS) 15b of the Web site to which the content 15a belongs is distributed.

  As shown in FIG. 4C, the meta information (RSS) 15b includes information on the website itself (<channel>) and a list of parts (corresponding to <item>) in the content 15a. Each part <item> in the content 15a has basic attributes such as a title (<title>), URL (<link>), summary (<description>), update time (<dc: date>), and essential It has additional attributes such as non-category (<category>).

  FIG. 5 is a diagram illustrating a divided image when the Web content 15a is divided according to the Web content 15a and meta information (RSS) 15b acquired from the server device 10 in the client device 20.

  According to this, the Web content 15a is divided into blocks Br1 to Br4 with titles and blocks Brh and Brf without titles. The block Brn is a block composed of an area from the nth title in the Web content 15a to immediately before the next title. The block Brh is an area from the beginning of the content 15a to the time before the first title block Br1 appears, and Brf is a block consisting of an area immediately after the block Br4 having the last title to the end of the content 15a.

  As described above, each part in the Web content 15a is divided into blocks Brn for each title based on the meta information (RSS) 15b, and the update time for each title described in the meta information (RSS) 15b is used. By doing so, for example, the title blocks Br1 and Br2 of the newly arrived article are highlighted H (see FIG. 10A), and the title blocks Br1 and Br2 of the newly arrived article are enlarged and displayed, and the other blocks Brf and Br3 are displayed. , Br4, Brf are displayed in a reduced size (see FIG. 10B), and blocks Brf, Br3, Br4, Brf other than the title blocks Br1, Br2 of the newly arrived article are hidden (FIG. 10C). See) and can be displayed as Web pages P1 to P3 having a layout that is easier for the user to handle. .

  Next, the Web content drawing / display control function of the first embodiment in the client device 20 configured as described above will be described.

  FIG. 6 is a flowchart showing Web content drawing / display control / UI (User Interface) addition processing by the client device 20.

  FIG. 7 is a flowchart showing title element extraction processing by RSS accompanying the Web content drawing / display control / UI addition processing of the client device 20.

  FIG. 8 is a flowchart showing a block extraction process associated with the Web content drawing / display control / UI addition process of the client device 20.

  FIG. 9 is a flowchart showing a block display control process associated with the Web content drawing / display control / UI addition process of the client device 20.

  FIG. 10 is a diagram showing a page display example (part 1) based on the update time of the Web content accompanying the Web content drawing / display control / UI addition process of the client device 20.

  When the Web browser program 23a stored in the ROM 23 is activated in response to a user operation, and the Web content 15a distributed by the server device 10 of the Web site designated by the user is received and acquired, the Web content In 15a, the source structure of the HTML is analyzed and drawn in the frame buffer FB in the RAM 24 (step S1).

  Then, as shown in FIG. 4, it is checked whether or not the RSS URL by the <link> tag is clearly specified in the HTML source, so that the meta information (RSS) 15b for the Web content 15a exists. Is determined (step S2).

  If it is determined that the meta information (RSS) 15b for the Web content 15a exists (step S2 (Yes)), the meta information (RSS) is sent from the server device 10 that distributes the meta information (RSS) 15b. ) 15b is received and acquired (step S3).

  Then, the process proceeds to the title element extraction process by RSS in FIG. 7, and the title character string described in the meta information (RSS) 15b is searched, and the HTML element including the title character string is included in the Web content 15a. Is detected (step SA).

  That is, when title element extraction processing by RSS is started, a counter n for counting the number of items <item> in the meta information (RSS) 15b is initialized to “1” (step A1), and the meta information (RSS) ) A character string that matches (exactly matches or partially matches) the character string of the title <title> (for example, “today's article 1”) existing in the first item <item> of 15b is generated from the Web content 15a. Search is performed (step A2).

  When it is determined that the title character string “Today's article 1” that matches the meta information (RSS) 15b exists in the Web content 15a (step A3 (Yes)), a plurality of the same title character strings are present. It is determined whether or not it exists (step A4).

  If it is determined that there are a plurality of the same title character strings (step A4 (Yes)), the title character string having the strongest style is selected from the plurality of title character strings, and It is determined as a title element representing information (step A5). Here, “title string with strong style” means, for example, that the font is bold, the font size is large, the background is an image, the background or font is a different color from the surroundings, etc. It is judged on the condition that it is described as a style that is easy to draw.

  As a condition for determining a representative title element from the plurality of title character strings, a long sentence including a summary sentence described in the meta information (RSS) 15b is immediately used without depending on only the style. The title character string below may be determined as a representative title element.

  Then, the position of the title element (HTML) in the Web content 15a searched or determined in step A2 or A5 is stored (step A6).

  Then, the counter n is incremented (step A7), and it is determined whether or not the counter n exceeds the total number of items <item> described in the meta information (RSS) 15b (step A8).

  Here, when it is determined that the counter n does not exceed the total item <item> number of the meta information (RSS) 15b (step A8 (No)), the processing after the step A2 is repeated, A title element in the Web content 15a that matches the character string of the title <title> described in the next item <item> of the meta information (RSS) 15b is searched / determined, and its position is stored (step) A2-A6).

  Thus, when the position of each title element in the Web content 15a is stored based on the character string of the title <title> for each item <item> in the meta information (RSS) 15b, the series of RSSs is stored. The title element extraction process is terminated (steps A7, A8 (Yes)).

  Then, the process moves to the block extraction process in FIG. 8, and the block in the Web content 15a is extracted based on the position of the title element in the Web content 15a extracted and stored in Step SA, for example, as shown in FIG. (Step SB).

  That is, when this block extraction process is started, first, the range from the start position of the Web content 15a to immediately before the position of the first title element stored in the step SA is the first block (Brh). (Step B1), and a counter n for counting the number of blocks is set to "1" (step B2).

  Then, for all title elements stored in step SA, the range from the position of each title element to immediately before the position of the next title element is stored as a block (Br1, Br2, Br3), and the counter n Are sequentially incremented (steps B3 to B5).

  Then, the number n of blocks in the web content 15a extracted in the processing of the steps B1 to B5 is equal to or exceeds the number of title elements in the content 15a stored in the step SA. If it is determined that each block (Brh, Br1, Br2, Br3) up to the title element located immediately before the title element has been extracted and stored (step B5 (Yes)), the block in which the last title element is located The end position of (Br4) is determined and stored (step B6).

  In this step B6, for example, the end position of the text following the last title in the Web content 15a including the summary corresponding to the last title described in the meta information (RSS) 15b is set to the last An HTML structure similar to that of the previous block consisting of “title → body” extracted and stored in step B3 is stored as the end position of the block (Br4) where the title element is located. A search is made in correspondence with the position of the title element, and it is determined and stored as the end position of the block (Br4).

  Then, the range from the end of the last title element block (Br4) to the end of the Web content 15a is stored as the last block (Brf) (step B7).

  In this way, when each block (Brh, Br1 to Br4, Brf) in the Web content 15a is extracted and stored in the step SB, the block display control process in FIG. 9 is performed, and all the extracted blocks n On the other hand, display adjustment (step C3 → C4 / C3 → C5) is performed according to the presence / absence of the title and the attribute of the title / block.

  “Display control processing for each title attribute or block attribute” (step C3 → C4) for a block having a title to be adjusted for display, and “Display control processing for a block without a title” (step C3 → C5) The specific processing differs depending on what display function the Web browser program 23a wants to have.

  For example, as shown in FIG. 10A, when it is desired to display the updated information block in the Web content 15a as the Web page P1 with the highlight display H, each block having a title is displayed in Step C4. For each (Br1 to Br4), the update time <dc: date> corresponding to the title <title> described in the meta information (RSS) 15b is compared with the current time or the search history of the same website. It is determined whether or not the information is updated by comparison with a certain previous browsing time. The blocks (Br1, Br2) determined to be updated information are highlighted H, and the blocks (Br3, Br4) determined not to be updated information are displayed as they are.

  In step C5, the blocks (Brh, Brf) having no title are displayed as they are.

  As a result, information blocks (Br1, Br2) with new update times, such as newly arrived articles, can be displayed as highlighted Web pages P1 with the highlight display H.

  Further, for example, as shown in FIG. 10B, when a block of updated information in the Web content 15a is displayed in an enlarged manner and a block of information that has not been updated is displayed in a reduced Web page P2. In step C4, for each block (Br1 to Br4) having a title, the update time <dc: date> corresponding to the title <title> described in the meta information (RSS) 15b as described above. Based on the above, it is determined whether or not the information is updated. Then, the blocks (Br1, Br2) determined to be updated information are enlarged and displayed, and the blocks (Br3, Br4) determined not to be updated information are reduced.

  In step C5, blocks (Brh, Brf) having no title are reduced and displayed.

  As a result, blocks of information (Br1, Br2), such as newly arrived articles, whose update times are likely to be new and unread are magnified to make them stand out and easy to see, and blocks of old information that are highly likely to be read Or a block having no title can be displayed in a reduced size and displayed as a Web page P2 that can list more new arrival information.

  Further, for example, as shown in FIG. 10C, when it is desired to display a web page P3 in which blocks other than the updated information block in the web content 15a are hidden, the title is displayed in step C4. For each of the blocks (Br1 to Br4), the information is updated based on the update time <dc: date> corresponding to the title <title> described in the meta information (RSS) 15b as described above. It is determined whether or not. Then, the blocks (Br1, Br2) determined to be updated information are displayed, and the blocks (Br3, Br4) determined not to be updated information are not displayed.

  In step C5, the blocks (Brh, Brf) having no title are not displayed.

  As a result, only the information blocks (Br1, Br2) whose update time is likely to be new and unread such as newly arrived articles are displayed, and can be displayed as a Web page P3 that does not require attention to unnecessary old information. it can.

  FIG. 12 is a diagram showing a page display example (part 2) based on the update time of the Web content accompanying the Web content drawing / display control / UI addition process of the client device 20.

  That is, each block (Brh, Br1 to Br4, Brf) in the Web content 15a is extracted and stored by the block extraction process (step SB) in FIG. 8, and then the focus initialization process in FIG. 11 is started. Then, for each block (Br1 to Br4) having a title in the content 15a, the update time <dc: date> corresponding to the title <title> described in the meta information (RSS) 15b as described above. Based on the above, it is sequentially determined whether or not the information is updated information (new article) (step C41).

  Then, the first block (Br1) determined to be the updated information (new article) is identified (step C41 → C42), and the identified block (Br1) is identified as shown in FIG. It is displayed as a web page P4 aligned with an easy-to-view place such as the top of the screen (step C43).

  As a result, when the user-specified Web content 15a is displayed, an extra advertisement area is skipped and automatically scrolled so that the block (Br1) in which the new arrival information is described is at the top of the screen that is easy to read. P4 can be displayed.

  That is, after the blocks (Brh, Br1 to Br4, Brf) in the Web content 15a are extracted and stored by the block extraction process (step SB) in FIG. 8, the focusing UI addition process in FIG. 13 is started. Then, first, the process proceeds to the focus initialization process in FIG. 11 (step C40).

  In this focus initialization process, it is determined that blocks (Br1 to Br4) having titles in the content 15a are focus candidate blocks (step C41 (Yes)), and one block determined to be this focus candidate block The eye block (Br1) is specified (step C42). Then, as shown in FIG. 14A, the identified focus candidate block (Br1) is displayed as a focused (F) Web page P5 by highlight display or frame display (step C43).

  Thereafter, when a movement operation of the focus (F) is performed according to the user operation (step C44 (Yes)), it is determined whether or not a focus candidate block exists in the direction of the movement operation (step C45). If it is determined that there is a focus candidate block in the direction of the movement operation (step C45 (Yes)), the focus (F) is moved to the focus candidate block (Brn) of the movement destination (step C46). .

  Further, when a full-screen enlargement instruction operation is performed in response to a user operation (step C47 (Yes)), for example, as shown in FIG. 14A, the block (Br1) that is currently focused (F) is targeted. Then, as shown in FIG. 14B, the block (Br1) is displayed as a page P51 in which the entire screen is enlarged (step C48).

  Here, when a “return” instruction operation is performed in accordance with a user operation (step C49 (Yes)), the block (Br1) as shown in FIG. From the display state of the page P51, the display state of the Web page P5 on the previous screen focused (F) as shown in FIG. 14A is returned (step C410).

  The processes in steps C44 to C410 are repeated until a transition to another Web page is instructed or an end of the Web browser program 23a is instructed according to a user operation (step C411).

  As shown in FIG. 14A, in the display state of the page P5 in which the block (Brn) corresponding to the user operation in the Web content 15a is focused (F), the focused block (F) ( When an instruction operation for selecting (Brn) is performed, as shown in FIG. 14 (C), a jump is made to a body page P52 linked to the title of the block (Brn) and displayed. The instruction operation for selecting the block (Brn) may be an operation different from the instruction operation for enlarging the full screen, or instead of enlarging the entire screen using the same operation, You may make it jump to the page P52 of the text linked to the title of (Brn).

  Thereby, for each block (Brn) divided for each title of the Web content 15a, a desired block corresponding to a user operation can be freely focused (F) or linked to the focused (F) block. You can easily jump to the page of the text you want to display.

  The focus initialization process executed as the UI addition process described with reference to FIGS. 11 and 12 and the focusing UI addition process described with reference to FIGS. You may perform in combination with the block display control process demonstrated with reference to FIG.

  As a result, it is possible not only to preferentially display blocks (Br1, Br2) of information whose update time is new, such as newly arrived articles, for the Web content 15a acquired by the user's specification, but also freely to a desired block It becomes possible to focus (F) or easily jump to a body page linked to the focused (F) block.

  In the block display control / UI addition process described with reference to FIGS. 9 to 14, the main process is to display the block corresponding to the new information more easily and in detail, but the contents of each block are simplified. It is good also as processing which improves listability. For example, for each block Brn in the Web content 15a extracted by the block extraction process in FIG. 8, the body part other than the title is not displayed, or the same body part is summarized from the meta information (RSS) 15b (there should be For example, a predetermined number of characters at the beginning of the text is cut out) to make it easy to grasp the entire content 15a, and the text is jumped and displayed as necessary.

Then, the web page P1 ′ of the link destination content 15a generated by the block division by the web content drawing / display control / UI addition process is displayed as a pop-up preview screen GP.

  According to this, for the content 15a of the link destination Web site designated in accordance with the user operation on the already displayed Web page, the page P1 ′ that preferentially displays the updated (new arrival) information of the content 15a is generated. And displayed on the pop-up preview screen GP.

  Therefore, according to the Web content drawing / display control function of the first embodiment in the client device 20 having the above configuration, the title character string in the meta information (RSS) 15b indicating the outline of the Web site is displayed in the Web browser (23a). The title element in the Web content 15a is specified, and the content 15a is divided into blocks (Brn) using the title element as a delimiter. At the same time, the content of the meta information (RSS) 15b and the user data (browser 23a) Display control of each divided block in the Web content 15a is performed using a Web search history, a bookmark, and the like.

  This means that the user can easily and surely see the desired web content 15a from the analysis of the conventional HTML tag structure without requiring any additional information or operation from the web site provider or web browser user. Can be divided into blocks for each title element, and display control can be easily performed. Therefore, not only the PC, but particularly the comfort of Web browsing not only on the mobile terminal but also on the mobile terminal which has imposed great stress on the user due to the small screen and poor operation means.

  In the first embodiment, the title element in the content 15a of the website is extracted and divided into blocks based on the title character string in the meta information (RSS) 15b indicating the outline of the desired website. did. On the other hand, as will be described with reference to FIGS. 18 and 19 of the second embodiment, the title elements in the Web content 15a that are not included in the title character string in the meta information (RSS) 15b. As for the configuration, the display style of the text of the title element already extracted by the extraction process of the title element using the meta information (RSS) 15b is acquired, and the text that matches the display style is extracted as the title element.

  That is, after the meta information (RSS) 15b corresponding to the Web content 15a is acquired in step S3 in the Web content drawing / display control / UI addition process in FIG. 6, the title element extraction process by RSS + style in FIG. When started, first, in the title style information memory 24a (see FIG. 19) in the RAM 24, style information about the title element in the Web content 15a is stored in association with the URL of the Web site currently displayed. It is determined whether or not it has been performed (step E1).

  The style information about the title element in the Web content 15a includes the Class name described as an HTML element in which display style rules such as the font size and font color of the text of the title element are embedded, Class Consists of a combination of individually specified style rules.

  Here, since the style information of the title element corresponding to the URL of the Web site acquired for the first time is not yet stored in the title style information memory 24a, it is determined that there is no title style information (step E1 (No)). Then, the process proceeds to the title element extraction process by RSS in FIG. 7 described in the first embodiment (step EA).

  When the position of each title element in the Web content 15a is extracted and stored by the title element extraction process (steps A1 to A8) by RSS, the style described in the HTML data corresponding to the title element is stored. Information is acquired and stored in the title style information memory 24a (step E2).

  Then, each text element described in the Web content 15a is sequentially extracted from the top of the content 15a (Steps E3 and E4), and the style information about the extracted text element is displayed on the currently displayed Web site. It is determined whether or not it matches the style information stored in the title style information memory 24a in association with the URL (step E5).

  When it is determined that the style information of the text element extracted from the Web content 15a matches the style information stored in the title style information memory 24a in association with the URL of the Web site. (Step E5 (Yes)), the text element is stored as the title element and the position is stored (Step E6).

  On the other hand, if it is determined that the style information of the text element extracted from the Web content 15a does not match the style information stored in the title style information memory 24a in association with the URL of the Web site ( In step E5 (No), the same extraction determination process as described above is repeated for the next text element (steps E7, E8 → E4, E5).

  Thereafter, when all the text elements extracted from the Web content 15a are subjected to a determination process for determining whether or not the text element is a title element and a storage process for the position in the case of the title element (step E4). To E8 (Yes)), the series of RSS + style title element extraction processing ends.

  If the same Web content 15a is acquired from the same Web site for the second time and thereafter, the content is based on the style information of the title element of the Web site already stored in the title style information memory 24a. Each title element in 15a is extracted and its position is stored (steps E1-> E9, E3-E8).

  As a result, the title elements in the site content 15a not included in the title character string in the meta information (RSS) 15b can be reliably extracted, and the positions of all the title elements can be stored. Therefore, after the block extraction process (step SB) and the block display control / UI addition process executed after this process, the Web content 15a is surely divided into blocks for all the title elements, and the first implementation is performed. As with the form, it is possible to perform page display control that is easy for the user to see.
