Description

  The present invention relates to a markup language processing apparatus that processes a document described in a markup language, and more particularly to a display processing method thereof.

  Documents and the like browsed on a website on the Internet are usually documents written in a markup language such as HTML (Hyper Text Markup Language). Documents written in a markup language are themselves text, but include font decoration, character decoration information such as font size and color, image settings, layout settings, and other items in the document. You can set links to other documents and images. Software (computer program) that performs processing for browsing document contents by interpreting tag information included in a document described in such a markup language and executing layout is called a browser.

  A “link setting location” is a location linked to another location in the same document or other document (including an image) or a specific function by an anchor tag. Usually, an underline, frame, A display that shows that the link is set is made by highlighting the color or the like. By instructing the link setting location by the user, processing such as movement of the display location or activation of a specific function can be performed. Such a link setting location can be selected by directly clicking with a pointing device such as a mouse in a personal computer or moved to the link destination.

  A mobile phone having a web browsing function can interpret and display a document written in a similar markup language (ML). In addition to the above HTML, compact HTML, XML (eXtensible Markup Language), BML (Broadcast Markup Language), and the like are known as markup languages. BML is known as a language used in data broadcasting rather than the Internet.

Patent Document 1 discloses a technique for selecting a plurality of link setting locations on a browser window and simultaneously processing the plurality of links according to a predetermined user operation.
JP 2000-20384 A

  Web browsing is also possible on TV devices and mobile phones having a function that can be connected to the Internet, but pointing devices (hereinafter referred to as direct instruction means) that directly instruct link setting locations such as a mouse or a touch panel. In general, an apparatus that does not have () has an operation key (or button) for sequentially moving the focus of the link setting location. In this specification, the focus is also considered as a kind of cursor, and this cursor movement operation means is called focus movement operation means.

  In such an apparatus, the link setting location is a focus target, and the focus can be moved sequentially to different link setting locations by operating the focus movement operation means to move the focus in a desired direction up, down, left, and right. It has become. The instruction to move the focused link setting location to the link destination can be made by, for example, pressing the enter key.

  In such a series of operations such as focus movement by the focus movement operation means, page switching, and focus target determination instruction, there are useless (redundant) operations in light of the standard operation procedure of the user.

  In such a background, the present inventors intend to provide a display processing method, a display processing program, and a markup language processing apparatus capable of simplifying the procedure of an anchor point instruction operation after switching display contents. Is.

  A display processing method according to the present invention is a display processing method in a markup language processing apparatus for processing a document described in a markup language, the step of acquiring the markup language document, and the acquired markup language document Analyzing and displaying a page including the anchor point, and when an anchor point in the displayed page is designated, information specified by the URL designated by the designated anchor point is acquired and displayed. A step of storing the designated anchor point, and displaying the markup language document when a “return” instruction is issued, and focusing on the next anchor point of the stored anchor point. And a step for setting.

  According to the present invention, a user displays a markup language document as a page, designates an anchor point in the page, shifts to display of information specified by the URL specified by the anchor point, and then returns to “Return”. When the instruction is performed, the focus moves to the anchor point next to the instructed anchor point. In normal user operations, when returning to the original page, there is a high possibility of moving the focus to the “next” or subsequent anchor point, so the focus is automatically set to the “next” anchor point. By moving to, the number of instruction operations required by the user can be reduced, and it is possible to immediately move to the next anchor point instruction.

  The next order direction may be a predetermined direction for a plurality of anchor points included in the page, or is determined based on a history of instructions for a plurality of anchor points included in the page. It may be a direction.

  Instead of targeting all anchor points as candidates for the next-order anchor point, the anchor points that do not satisfy the predetermined condition are excluded, or the anchor points that satisfy the predetermined condition are selected. In addition, anchor points having a predetermined attribute that is unlikely to be designated by the user may be excluded.

  In the step of acquiring and displaying the information specified by the URL specified by the instructed anchor point, the display content is specified in the URL by switching the display content in the same window as the window in which the markup language document is displayed. In the case of a so-called tab browser, a second tab different from the first tab on which the markup language document is displayed is generated and the second tab is selected. The information specified by the URL may be displayed. In the latter case, the “return” instruction may correspond to switching the active tab from the second tab to the first tab. .

  In the step of acquiring and displaying the information specified by the URL specified by the instructed anchor point, a second window different from the first window in which the markup language document is displayed is opened. The information specified by the URL may be displayed in a second window. In this case, the “return” instruction corresponds to switching the active window from the second window to the first window. To do.

  Another display processing method according to the present invention is a display processing method in a markup language processing apparatus for processing a document described in a markup language, the step of acquiring a markup language document, and the acquired markup language Analyzing the document and displaying a page including the anchor point; and when an anchor point in the displayed page is designated, information specified by the URL designated by the designated anchor point is acquired. And displaying the instructed anchor point, and the URL specified by the next anchor point of the stored anchor point when the “next decision” instruction is performed. And a step of acquiring and displaying information.

  By the “next determination” instruction, the user can acquire and display information specified by the URL specified by the next anchor point of the stored anchor points without performing the focus movement operation and the determination operation. Can do.

  The present invention can also be understood as a markup language processing device and a display processing program executed in the device for carrying out each of the above display processing methods.

  According to the present invention, when the display content is switched by a “return” instruction or the like in the markup language processing device, a focus operation by the user is required as an anchor point of a movement destination that is predicted to move with a high probability. Therefore, since the focus is automatically moved to the “next anchor point” of the “stored anchor point”, it is possible to simplify the procedure of the user's instruction operation for the anchor point.

  In addition, in response to the “next determination” instruction, the user acquires and displays information specified by the URL specified by the next anchor point of the stored anchor points without performing the focus movement operation and the determination operation. Can be made. Thereby, it is possible to further simplify the procedure of the user's operation of specifying the anchor point.

  This simplification of the instruction operation procedure enables the user to quickly view the document created in the markup language without operation frustration even in an apparatus that does not have direct instruction means. Become.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the drawings.

  FIG. 1 shows the appearance of a television device (a) and a mobile phone (b) given as examples of a markup language processing device to which the present invention is applied.

  The television device 55 in the present embodiment is an example of a television device compatible with data broadcasting, that is, BML and HTML, and a dedicated remote controller 50 is attached. The television device 55 can display not only broadcasting but also information obtained via a communication network such as the Internet. The remote controller 50 is provided with so-called color buttons 70a to 70d in addition to channel keys and other keys. A specific color such as red, blue, yellow, or green is previously assigned to the color button, and a corresponding predetermined function or the like is assigned. The remote controller 50 has up / down / left / right direction instruction keys (75a to 75d), an enter key 76, and the like. (When the direction instruction keys 75a to 75d are generically referred to, they are simply referred to as instruction keys 75. The same applies to other reference numerals.)

  The remote controller 50 may be a remote controller that does not have a color button or the like. The communication medium of the remote controller 50 is generally infrared (IrDA), but is not necessarily limited to infrared, and may be wired or wireless.

  The television device 55 shown in FIG. 1A shows a built-in markup language processing device, but is a type in which a markup language processing device such as a so-called set-top type is externally attached to the television device body. There may be.

  1B is a folding type in which an upper casing having a display 8 and a lower casing having an operation section 13 including various keys such as a numeric keypad and a cursor movement operation key are coupled by a hinge section. Shows the equipment. However, it does not matter whether the mobile phone to which the present invention is applied is a half-fold type. An instruction to move the focus target can be given by a cursor movement operation.

  FIG. 2 is a block diagram illustrating a configuration example of the television device 55. The television device 55 is an information processing device in which the browser according to the present embodiment is installed, and includes a central control unit 201, a RAM 202, a ROM 203, a display driver 204, a display 205, a network interface 206, and a user interface. (UI) device interface 207, flash memory 208, IR light receiving unit 209, antenna 211, and data broadcast compatible broadcast receiving unit 212.

  The central control unit 201, RAM 202, ROM 203, display driver 204, network interface 206, user interface (UI) device interface 207, flash memory 208, and broadcast receiving unit 212 are connected to each other via a bus 210. Data is exchanged and commands are exchanged.

  A RAM 202 is a memory that temporarily holds and stores calculation results of the central control unit 201 and data (including markup language documents) acquired from the outside. The ROM 203 is a non-volatile memory that stores programs such as an operating system (OS) and a browser 203a. The central control unit 201 reads these programs from the ROM 203 and executes predetermined processing according to the programs. The flash memory 208 is a rewritable nonvolatile memory that holds data acquired from the outside, information such as an e-mail address, URL, and the like for later processing. In this example, the browser 203a is stored in the ROM 203, but may be stored in the flash memory 208. The network interface 206 has a function of establishing a connection with an external network and transmitting / receiving data to / from an external network (such as the Internet), and is configured by, for example, a LAN board. The user interface device interface 207 has a function of receiving an input from the remote controller 50 via, for example, the IR light receiving unit 209 and passing it to the central control unit 201. When receiving the infrared signal emitted from the remote controller 50, the IR light receiving unit 209 has a function of converting it into an electric signal and passing it to the user interface device interface 207.

  The display driver 204 has a function of receiving display information such as a document or an image from the central control unit 201 and driving the display based on the display information. The display 205 is an arbitrary display device such as a liquid crystal display device, a CRT display device, or a plasma display device, and has a function of optically displaying a screen based on a drive signal from the display driver 204. The broadcast receiving unit 212 has a function of extracting a signal of a desired channel from a broadcast wave received by the antenna 211 and demodulating and reproducing the signal. This broadcast receiving unit 212 may correspond to terrestrial data broadcasting for mobile phones.

  FIG. 3 shows a hardware configuration example of the mobile phone 10. Control of the mobile phone 10 is realized by program control of a central control unit (for example, CPU) 1. The ROM 2 is a normal read-only memory that stores a control program for that purpose, an initially installed application program, and fixed data. The RAM 3 is a readable / writable memory that provides a temporary data storage area and work area. The flash memory 4 is a rewritable memory that stores various data as described above in a nonvolatile manner. The browser 2a is stored in the ROM 2 (however, it may be stored in the flash memory 4). The wireless network interface 6 is a part that performs wireless voice and data communication with the base station via the antenna 5. The display driver 7 is controlled by the central control unit 1, performs drawing processing of various information, and displays on the display screen of the display 8 that is a display unit. The user interface device interface (I / F) 13 is a part that controls input / output operations of the user interface device 14 such as a key operation unit including various operation keys, a microphone, and a speaker under the control of the central control unit 1. In addition to these, the mobile phone 10 may include a broadcast receiving unit such as a terrestrial data broadcast, although not shown.

  Here, a schematic configuration of the browser 203a (or 2a) will be described with reference to FIG. The browser 203a (or 2a) has the browser engine 20 as its main functional unit. The browser engine 20 includes functional blocks of a parser 21, a page maker 23, and a formatter 25. The parser 21 interprets the logical structure of the markup language (ML) document 19 to be displayed, and generates a document tree 22 related to the structure. Based on the document tree 22, the page maker 23 generates a layout tree 24 including information on the expression format (block, inline, table, list, item, etc.) determined by each tag. This layout tree 24 represents the order in which block, inline, table, etc. exist. However, the layout tree 24 does not yet include information relating to the layout such as where and in what width and height these elements are displayed on the screen, and where characters are folded. Based on the layout tree 24, the formatter 25 performs layout using information related to the actual display screen such as a known display screen width. That is, the layout tree 24 is arranged on the actual display screen, and the character wrapping and the position, width, and height on the screen are determined. Through such processing by the browser engine 20, the markup language document 19 is displayed on the display screen.

  The “document written in the markup language” (markup language document 19) is a text document before being analyzed by the browser. In addition, “focus target” is a link setting location, that is, an anchor point, to be a focus target defined by an anchor tag in a markup language document.

  FIG. 5 is a diagram for explaining an operation example in the first embodiment of the present invention. In this example, a page 80a is shown in which a markup language document indicating a result of a search by a keyword on an Internet search site is acquired, analyzed, and displayed. ("ACCESS" in the figure is a registered trademark of ACCESS Co., Ltd.) In this page, a plurality of link setting locations, that is, anchor points 101 to 112 are set, as shown by the underline. Further, the focus 81 is applied to one anchor point at a time. The specific display form of the focus 81 is not particularly limited, and arbitrary highlighting such as inversion, frame, and color change is sufficient. The focus 81 is sequentially moved onto each of the plurality of anchor points to be focused in a predetermined order by the operation of the remote controller 50 or the operation unit 13 of the mobile phone 10 described above. Normally, the first anchor point in the page (an anchor point 101 in the page 80a) is the default focus position, and the focus is sequentially moved from here to the next anchor point. In this example, when the determination key 76 (similar key on a mobile phone) is operated while the focus is on the first anchor point (character string “ACCESS”) of the page 80a, the specified anchor point is designated. The information specified by the URL, in this example, the ML document corresponding to the page 80b is acquired and displayed.

  The page 80b displayed by the instruction (82) of one anchor point 101 in the page 80a may be displayed in the same window as the page 80a, or a new window may be opened and displayed therein. . In the former case, when the “return” instruction 84 is made, the display content is switched in the same window, and the markup language document of the page 80a is displayed again. In the case of the tab browser, the “return” instruction 84 corresponds to switching the active tab from the second tab of the page 80b to the first tab (the page 80c having the same content as the page 80a). When opening a new window, a second window different from the first window in which the page 80a is displayed is opened to display the page 80b in the second window, and the “return” instruction changes the active window to the page 80b. Switch from the second window to the first window of page 80a.

  The focus 81 that was at the anchor point 101 on the page 80 a moves to the anchor point 104 on the page 80 c in response to the “return” instruction 84. Conventionally, the focus 81 returns to the default position in response to the “return” instruction 84, but in this embodiment, the focus position in the page 80a when the page 80b is shifted to is stored, and the page 80a (ie, 80c) is stored. When returning, the focus 81 is set to the anchor point 104 next to the stored anchor point 101. Before giving a “return” instruction from the page 80b, there may be a “detour” in which an anchor point in the page 80b is instructed to move to another page and return. When the enter key is pressed with the focus 81 on the anchor point 104 on the page 80c (86), the corresponding page 80d is displayed.

In this specification, the “next order” is basically determined based on a predetermined order determined by the configuration of the ML document before or after the processing. However, the direction may be the reverse direction. Further, as the “next order” anchor point, when the anchor point immediately after the direction does not satisfy a predetermined condition, the anchor point may be excluded from the movement of the focus. An anchor point that does not satisfy the predetermined condition in this case is an anchor point that is unlikely to be selected by the user. Alternatively, an anchor point immediately after the direction and satisfying a predetermined condition may be selected as a focus target. As described above, the “predetermined condition” can include a passive condition and a positive condition. For example, the predetermined condition is as follows.
(1) Positional conditions of the anchor point to be focused For example, when the display element is divided into a plurality of blocks as in the page 80a in FIG. 5, the page is at a predetermined position in the block (for example, the block Must be the first anchor point in
(2) An attribute condition of the anchor point to be focused. For example, the name of the anchor point does not correspond to a predetermined keyword. The predetermined keyword is “cache” and “related page” in the example of the page 80a in FIG. )
(3) Special ordering of anchor points to be focused If the anchor points are specially ordered in the ML document or its accompanying information, the order is followed.
(4) Conditions depending on the anchor point target The display area designated as the anchor point target stored last in a specific display area is another display area (for example, another window) on the same display screen. When an instruction to return from the target display area to the specific display area is given, among the anchor points subsequent to the last stored anchor point, the target display area is the other display area. The previous anchor point is the next focus target.

  In the page as shown in the page 80a in FIG. 5, when returning to the other page (80b or the like), the probability that the user will indicate next is the “next order” anchor point or It is an anchor point after that. Therefore, it is preferable that the focus target when returning to the page 80a is not the default anchor point but the “next order” anchor point of the anchor point that is the source of the transition to another page. Even if the actual target anchor point is further succeeding, if the focus point is moved sequentially by the cursor movement operation, the target anchor point will be faster than starting from the default position. Can reach the following.

  In the page 80c of FIG. 5, since the next anchor point 104 is already automatically focused, if the user gives a determination instruction, the information specified by the URL specified by the anchor point, in this example, the page An ML document corresponding to 80d is acquired and displayed.

  It is also possible to store a user instruction history regarding the focus moving direction and dynamically switch the focus moving direction according to the history. For example, in the page 80a (or 80c), when the user designates an anchor point by an explicit instruction operation to display another page and returns to the original page again, the previous (an order of the order) of the anchor point is displayed. When the focus is moved to the anchor point located at (above) and a determination is instructed, the next anchor point can be selected as the focus target in reverse order when returning from the transition destination page.

  Further, in a state where the page 80b is displayed, the original page 80a (80c) is returned by a predetermined user operation, for example, an instruction of a predetermined key 77 (next determination key) of the remote controller 50 or a menu selection instruction. Instead, the ML document corresponding to the next anchor point 104 of the stored anchor point 101 (or the most recently stored anchor point if there are a plurality of stored anchor points) is acquired and displayed as page 80d. To do. According to this “next determination” operation, the operation that serves as the “return” instruction and the “decision” instruction after the automatic movement of the focus to the next anchor point on the original page described above is performed once. Can be realized.

  FIG. 6 shows an application example of this embodiment to a so-called tab browser. The tab browser is similar to a “tab” that is usually attached to a paper-based folder for managing paper files, and helps to identify and select multiple windows on the display screen. A window display screen including a window provided with a tab portion is used. In FIG. 6, the window display screen 90 includes tab portions 91 to 94. Since the windows of each tab part are completely overlapped except for the tab part, only one window is substantially opened on the screen. In a general browser, every time a new page is opened, a new window is opened on the screen, and the screen overflows with windows, which makes the operation troublesome. On the other hand, the tab browser has only one substantial window, and when a new page is created, a tab is added and displayed in the window. Therefore, a large number of windows are not generated on the screen. The page of the tab that is not currently selected is only hidden, and can be immediately displayed (activated) by selecting the tab. In the example of FIG. 6A, tab pages 91 to 94 are assigned to four pages respectively corresponding to the color buttons 70a to 70d of the remote controller 50, and the page of the tab 91 is currently active.

  In the blue tab page 90a of FIG. 6A, when the anchor point with the focus 81 is instructed by the enter key 76, the information specified by the URL specified by the anchor point, in this example, another ML When the document is acquired, another tab (tab 92 in this example) as shown in FIG. 6B is activated, and the page 90b of the other ML document is displayed on the active tab instead of the page 90a. . In the case of such a tab browser, the “return” instruction corresponds to switching the active tab from the tab 92 to the tab 91. In accordance with the switching of this tab, the display content in the window is switched from the page 90b to 90a.

  Note that an upper limit (four in this example) may be provided for the number of tabs displayed simultaneously. In addition, one tab may be initially displayed, and a new tab may be generated every time a new page is opened.

  Also in the case of the tab browser in FIG. 6, the “next determination” operation described above can be performed. That is, in the state where the page 90b (FIG. 6B) is displayed, the original page 90a (FIG. 6 (FIG. Without returning to a)), an ML document corresponding to the anchor point 112 next to the stored anchor point 111 can be acquired, and another page (for example, the tab 93) can be activated to display the page.

In addition, the following several methods are conceivable as to which anchor page to be used as the target of “next determination” should be in the page of which tab, and any of them may be used.
(1) The page to which the anchor point to be determined next belongs is a page of a predetermined tab (for example, the blue tab 91). This predetermined tab may be fixed, or the user may be able to specify an arbitrary tab by default. Alternatively, when a page is displayed on an arbitrary tab, the user can specify that the page on this tab is “the page to which the anchor point to be determined next belongs”.
(2) The page to which the anchor point to be determined next belongs is the page of the tab opened first (or first active).
(3) A page to which an anchor point to be determined next belongs is a page of a specific site such as a search page (for example, when there are a plurality of tabs of such a page, for example, it is the latest active page, etc. Page satisfying a predetermined condition).

  In the above description, the case where the page is switched and displayed in the same window including the case of the tab browser has been shown. However, as shown in FIG. 7, a new window (display area) is displayed each time a new page is displayed. The present invention can also be applied to a display form in which a) is opened. Here, in response to an instruction to determine “anchor point 1” in the window 131 in FIG. 7A, the window 132 is additionally opened in the window 131 as shown in FIG. 7B, and the window 131 is activated. An example in which a new window 133 is additionally opened by returning to and instructing to determine “anchor point 2” is shown. In the figure, an example in which a plurality of windows are displayed overlappingly is shown, but they may be displayed without overlapping. Even when such a plurality of windows are opened, one active window is managed at a time as a window to which the cursor movement operation is applied.

  Hereinafter, a display process for realizing the operation of the present embodiment will be described with reference to a flowchart. This process is mainly executed by a browser program.

  FIG. 8 is a flowchart showing a first example of display processing in the present embodiment. First, markup language (ML) document data to be displayed is acquired (S11). This acquisition is typically performed by reception from a WEB server via the Internet. However, acquisition is optional, such as acquisition from a server in a LAN or a local storage device. Absent.

  The acquired ML document is analyzed to generate page display information, which is displayed on the screen as a page including an anchor point (S12).

  If there is a focus movement and determination instruction by the user for an arbitrary anchor point on the displayed page (S13, Yes), the anchor point is temporarily stored (S14). Next, ML document data of the page of the anchor point is acquired (S15). The acquisition of ML document data in this case is as described above. The acquired ML document is displayed in the window of the original page or in a window opened separately as described above (S16).

  If there is no anchor point instruction in step S13, it is checked in step S17 whether there is a "return" instruction. As described above, the “return” instruction in this specification includes an instruction to switch to a tab or window of the original page. If there is a “return” instruction, it is checked whether there is a previous page (S18). For this purpose, as is well known, history information of the viewed pages is temporarily stored. Even if the “return” instruction is given on the first page displayed when the browser is started, there is no previous page.

  If the immediately preceding page exists, ML document data of the immediately preceding page is acquired (S19). The acquisition of the ML document (and the focus position) can be performed from the cache memory when the data exists in the cache memory in the apparatus (the same applies to the acquisition of the ML document described later). Therefore, this ML document data is displayed (S20). At this time, the focus is placed on the next anchor point stored in step S14 (S20). If the user gives a “decision” instruction with the next anchor point determined, the anchor point is executed.

  If there is no “return” instruction in step S17, it is checked in step S21 whether there is a “forward” instruction. If there is a “forward” instruction, it is checked whether there is a page immediately after (S22). There is no page to be advanced to after the “return” instruction is given. For this purpose, the history information of the browsed page is referred to. When the immediately following page exists, the ML document data of the immediately following page is acquired (S23) and displayed (S24).

  Although not particularly illustrated, it is also possible to give a “decision” instruction by moving the focus to an arbitrary anchor point by a cursor operation by a user on an arbitrary page.

  The method for determining the “next-order anchor point” has been described above. Next, an example of a specific method for determining the “next-order anchor point” will be described with reference to FIG. This method is applicable when the ML document to be displayed can be grasped as a plurality of blocks as shown on the page 80a in FIG.

  First, based on the analysis result of the given ML document, it is checked whether there is an anchor point next to the currently focused anchor point (for example, immediately after in the forward direction) (S31). If it exists, it is checked whether or not the anchor point belongs to the same block (S32). If it belongs to the same block, the anchor point is ignored and the next anchor point is searched (S31). This makes it possible to skip subsequent anchor points in the same block (for example, anchor points 102 and 103 of the first block in the page 80a).

  If an anchor point that does not belong to the same block is found, that block is the first anchor point of the next block, and that anchor point is determined as the next anchor point (S33).

  FIG. 10 is a flowchart showing another example of a specific method for determining “next anchor point”. In this process, an anchor point having a specific attribute is excluded from candidates for the next anchor point. Here, the name assigned to the anchor point is used as a specific attribute, and an anchor point whose name matches a keyword registered in advance is excluded.

  First, based on the analysis result of the given ML document, it is checked whether there is an anchor point next to the currently focused anchor point (for example, immediately after in the forward direction) (S41). If it exists, it is checked whether or not the anchor point includes a name that matches the registered keyword (S42). If a name that matches the registered keyword is included, the anchor point is ignored and the next anchor point is searched (S41). This makes it possible to skip subsequent anchor points having the attribute.

  If an anchor point that does not include a name that matches the registered keyword is found, that anchor point is determined as the next anchor point (S43).

  The rules adopted in the next-order anchor point determination process as shown in FIGS. 9 and 10 may differ depending on the page to be displayed. Therefore, rule information may be registered in advance for a predetermined page (or registered by the user), and the corresponding rule information for the page may be selected and applied. Therefore, as shown in FIG. 11, as a modification of the present embodiment, a data table 300 in which a page (for example, URL) 301 is associated with a corresponding rule information pointer 302 is prepared and designated by the rule information pointer 302. The rule information 303 corresponding to the stored location is stored. These data tables and information can be stored in a non-volatile manner, for example, in the flash memory 4, 208 or the like. The rule information corresponding to each pointer can be updated.

  FIG. 12 is a flowchart showing an example of the next order determination process for determining the next order anchor point. This process is activated when each page is displayed. First, it is checked whether the page is a predetermined page (S51). This can be performed using, for example, a data table 300 as shown in FIG. If it is not a predetermined page, this process is terminated.

  If it is a predetermined page, the storage information designated for the page is acquired (S52). This can also be performed using the data table 300 as shown in FIG.

  Thereafter, when it becomes necessary to determine the next anchor point (S53, Yes), the next anchor point is determined according to the acquired storage information (S54).

  If the page is closed or the browser is terminated (S55, Yes), this process ends.

  The processing in FIG. 12 is not essential in the present invention, but if this processing is adopted, it becomes possible to flexibly deal with individual pages.

  Next, a second example of display processing in the present embodiment will be described with reference to FIG. In FIG. 13, the same processing steps as those shown in FIG. The process of FIG. 13 is different from the process of FIG. 8 in that step S14a is added after step S14. That is, the designated anchor point is sequentially stored as a history of the user's instruction, and automatic focus movement is performed according to the relationship between the newly designated anchor point and the anchor point designated immediately before in the same page. The direction of “next order”, which is the direction, is determined. Accordingly, the focus moving direction is dynamically switched according to the history information of the user instruction. The determination of the next anchor point is as described above, and the processing described with reference to FIGS. 11 and 12 can be employed.

  FIG. 14 is a flowchart showing a third example of the display process in the present embodiment. Also in FIG. 14, the same processing steps as those shown in FIG. The process of FIG. 14 differs from the process of FIG. 8 in that steps S25 to S27 are added after step S24. This added step supports the “next decision” operation described above.

  When the “next determination” operation is performed in step S25 (S25, Yes), ML document data of the page of the anchor point next to the anchor point stored in the page browsed immediately before is acquired (S26). Next, this ML document is displayed (S27). After step S27, the process returns to step S13 to repeat the above process. For the determination of the next anchor point in the “next determination”, any method described above can be adopted.

  The preferred embodiments of the present invention have been described above, but various modifications and changes other than those mentioned above can be made.

  For example, in any display process, the time to obtain the “next order” anchor point is determined when there is a “return” instruction. From the original page, the anchor point determination instruction is sent to the destination page. You may make it obtain | require beforehand, when moving. In this case, the anchor point temporarily stored may be the “next” anchor point, and the focus may be set by referring to the temporarily stored anchor point when the “return” instruction is given.

  The present invention is suitable for application to an apparatus having no direct instruction means as described above, but does not exclude application to an apparatus having direct instruction means. The focus movement operation means may be used in combination with the direct instruction means. In particular, the “next determination” operation is also useful for an apparatus having direct instruction means. In this case, the “next decision” button does not need to be a mechanical key or button, but may be a software button displayed on the screen and directly designated by the instruction means.

  Furthermore, the present invention can also be applied to search processing of various data in a predetermined device or a local network. In other words, when the user issues a “search” button instruction for an arbitrary character string, etc., various data in the device or local network corresponding to the character string to be searched (in a document written in a markup language). (Not limited) is searched, and a list as a search result is created. Anchor points are created in this list, and when any anchor point is designated, the corresponding data (file) is expanded and displayed in another display area (for example, another window). The present invention can be applied between the display area of the search screen and the other display area in such a search process.

  Also, on any browser, pressing the “Favorite” button will display a list of URLs designated as favorites, and pressing the “History” button will display a list of URLs stored as history. Also for those to be processed, the automatic transition of anchor points of the present invention to “next order” and “next determination” can be applied.
