This application is based on and claims priority from prior Japanese Patent Applications No. 2005-021715 filed on January 28, 2005 and No. 2005-022229 filed on January 28, 2005, which are hereby incorporated by reference The entire content of the application is incorporated by reference. the

technical field

The present invention relates to a display device for displaying Web pages, for example, preferentially displaying predetermined items according to a plurality of specified priority conditions. the

Background technique

The following first to sixth related arts propose systems and methods for preferentially displaying predetermined items according to priority conditions. the

The first related technology is an information system including a mobile memory and an information terminal for accessing the mobile memory. By operating the operating portion of the information terminal, the user can select one of a plurality of options displayed on the screen, and can search for desired information. In this case, data related to the selection of options when the user accesses desired information is stored in the database of the mobile memory and used to prepare the user's data entry history. Thereafter, when the user uses the information terminal to search for information next time, the data input history stored in the mobile memory is referred to and used to preferentially display the previous options frequently performed by the user. the

The second related art is a content pre-reading method for determining the pre-reading order of pre-reading the contents of these web pages using the priority levels of web pages at individual link destinations, and determining the priority levels based on past access frequencies (for example, see JP-A-11-219313). the

The third related technology is an on-screen display control system. According to the system, an on-screen display for a display screen is provided according to priority item data selected from a priority display selection menu, data on the date and time at which the item was selected, and recorded data on when the menu was actually selected. right. Then, the display position of the menu item to which the priority is assigned is changed, and thereafter, the menu item is displayed on the screen of the terminal. the

The fourth related technology is a display method that checks a user's profile and positions a cursor on an information element (hyperlink) of information determined based on past selected times and tasks presented by the user when the user accesses. the

A fifth related art is a web page pre-reading system comprising: a link table in which a list of link destinations for individual web pages is entered into the link table together with a selection frequency obtained based on a previous history; a table update section for Updating the content of the link table when a link is selected; and a web page pre-reading section for pre-reading data of URLs frequently selected in the past based on the content of the link table (for example, see JP-A-11-249823). the

A sixth related art is a display method that, when a Web page is updated, compares the updated Web page with a cache file, and displays the updated text data portion for identification using other text data portions (for example, see JP- A-2001-34525)

JP-A-11-219313, JP-A-11-249823, and JP-A-2001-34525 are cited as related art. the

With the widespread use of portable terminals such as cellular phones and PDAs, the use of cellular phones to browse Web pages through the Internet is increasing. the

It is assumed that most of these Web pages to be browsed with a device such as a personal computer having a large display device are generally not suitable for reading by a portable terminal having only a small display portion. the

In addition, small portable terminals such as cellular phones have limited input means. With a personal computer, it is assumed that a pointing device such as a mouse is provided as an input device, while with many cellular phones, only a small number of keys are available for browsing Web pages. the

As a method of browsing a large Web page or image using a small screen, the Web page is reduced so that the entire width of the Web page, or a complete Web page can fit in the display portion. the

However, many web pages have web pages that are much larger than the display portion of a cell phone. Therefore, according to this browsing method, when the Web page is reduced to fit the display portion, the reduction ratio of the characters on the Web page is too large to be readable. the

Furthermore, when browsing a Web page generated for a personal computer's display using a cell phone with only a small display device, the user must scroll the screen in many cases where only a less important portion (usually the upper left portion) is initially displayed. the

Therefore, when the user browses a large Web page using a cellular phone, in order to read information outside the display range of the display portion, the user must scroll the screen by pressing the key several times. Its disadvantage is that the user is forced to perform troublesome operations repeatedly. the

Therefore, the above method has been proposed for preferentially displaying the pre-reading items according to the priority order. However, according to the prior art of displaying items in order of priority, since priorities are assigned according to the number of historical selections and access frequencies, information of very important items actually required by the user is not always displayed. In addition, the related art cannot provide a mechanism for display when no information element satisfying the requirements of the highest priority item is available, and the next highest priority information element is displayed. the

In addition, there are cases where an information element that is given the highest priority on a particular web page does not even appear on another web page, and an information element that has a low priority on a particular web page has the highest priority on another web page . However, according to the prior art, priority cannot be assigned on a case-by-case basis, and these demands cannot be satisfied. the

That is, the prior art cannot initially display information important to the user, so that the user either has trouble identifying useful data or has to perform a troublesome scrolling operation. Therefore, the prior art has the disadvantage that required information cannot be quickly displayed. the

Detailed ways

Embodiments of the present invention are described below with reference to the drawings. the

[First embodiment]

FIG. 1 is a block diagram showing a portable terminal employing a display device according to a first embodiment of the present invention. the

The portable terminal 110 of the first embodiment is a device in which browser software capable of browsing Web pages is installed. Although the portable terminal 110 has only a small display portion, the device preferentially displays a portion on its display portion that includes important information to the user and does not require the user to perform a scrolling operation. the

The portable terminal 110 may be, for example, a cellular phone or a PDA. FIG. 1 depicts the functions performed by such a display device as a device for browsing Web pages according to the present invention. With the first embodiment, descriptions are mainly given concerning operations when the display device is used as a browsing device. the

According to the functions of the portable terminal 110 of the first embodiment, predetermined Web page information is acquired and stored. The new web page information is compared with the stored web page information, and when there is an updated (changed) element, for example, the updated element is displayed at a predetermined position and highlighted. the

Depending on the update type, the portable terminal 110 displays the element at a predetermined position while assigning priority. the

Update types include NEW, update, refresh, title change and change to another element or another item. the

When there are multiple updated elements, the update of these elements can be regarded as an update of one element, so that the change of the number can be regarded as not being updated. Additionally, the element on the predetermined Web page that is determined to be updated first is considered the element with the highest priority. the

When the number of updated elements is greater than the predetermined count, the portable terminal 110 does not perform an operation of displaying the updated elements at a predetermined position. the

Furthermore, in the first embodiment, the portable terminal 110 has a function capable of designating positions for display elements, for example, the center, upper left and upper right of the display screen can be designated as display positions. the

The portable terminal 110 of the first embodiment also has a function of calculating a scrolling distance required to display an element at a predetermined position so as to display an updated element at a position away from the initial position by the acquired scrolling distance. the

In addition, the portable terminal 110 of the first embodiment has a function of switching display so that an element with the highest priority is displayed on a predetermined Web page, and an element of low priority is displayed at a predetermined position. That is, the portable terminal 110 has a function of sequentially changing the display of elements with lower priority levels in accordance with user operations. the

As described above, the portable terminal 110 has a function of changing display positions in order of priority levels; however, this display switching may be performed by a user operation, or automatically performed after a predetermined period of time has elapsed. the

In addition, the portable terminal 110 has a function of virtually displaying the state that the display position moves to the next position with animation. the

The portable terminal 110 also includes the following functions:

When a predetermined number or more of the updated parts appear on the Web page, the Web page is determined to be refreshed, and the function of initial scrolling for displaying the updated parts is not performed;

The function of displaying the web page while reducing the size of the entire web page presented to the user at the location of the updated portion, and switching the display position so that the updated portion selected by the user is displayed at the original magnification;

When there are no updated parts, use an icon or message display to notify the function of the effect;

When comparing web pages that were acquired in the past but that do not appear in the web page storage section, the ability to display this effect using an icon or a message; and

When web pages are to be compared, and a link to a URL (uniform resource locator) of a domain different from the currently browsed web page is specified for the updated part, the part is not considered to be an updated part. the

Next, the structure and function of each part of the portable terminal 110 of the first embodiment, the initial Web page display operation, the operation performed when receiving a display candidate switch, the example of the layout of the Web page and the example of the updated part, in the browsing Initial display example provided at the time of Web page, display example of content for updated part, display example of presence/absence of update, example of moving display position using animation, processing example of detecting updated part, and moving display position An example of processing is described. the

As shown in FIG. 1 , the portable terminal 110 includes a webpage acquisition section 111 , a webpage storage section 112 , a timer 113 , a storage section 114 , an operation section 115 , a display section 116 and a control section 117 . the

The web page acquisition section 111 has a function of acquiring a Web page through, for example, a communication network using a communication function, and/or a function of acquiring a Web page from a recording device (not shown). the

The web page acquisition section 111 outputs the acquired Web page information to the control section 117 . the

When the portable terminal 110 is a cellular phone, the web page acquisition section 111 performs radio communication such as dialing a telephone number or sending or receiving electronic mail through a base station (not shown) using a communication section. the

Under the control of the control section 117, the webpage storage section 112 stores the webpage acquired by the webpage acquisition section 111, and information associated with the webpage. the

The timer 113 measures the currently elapsed time. The control section 117 refers to the date and time acquired by the timer 113 . the

Information on the updated portion of the Web page is stored by the control section 117 in, for example, the storage section 114 . the

The storage section 114 includes a nonvolatile memory such as EEPROM, and is used to store controls for performing voice communication or sending or receiving e-mail, an Internet browser, message data, and an address book in which names and phone numbers are registered. program. the

In the storage section 114, the element type extracted from the Web page information related to the URL object, the information relevant to the element and priority (priority level), indicating the time of browsing the Web page and the coordinates of the Web page are stored by the control section 117 Information. the

The operation section 115 includes a plurality of ten-key numeric keypads, and an end (speech end)/power key and a start (dial) key when the portable terminal 110 is a cellular phone. When the user operates these keys provided for the operation section 115, an instruction input by the user changes the priority, or information on a position designated by the user for displaying elements on the display section 116 is output to the control section 117. the

The display section 116 includes a display device such as a liquid crystal display (LCD), and displays mail received as text or various types of text data stored in the storage section 114 under the control of the control section 117 . the

In addition, the control of the display section 116 in the control section 117 formats the acquired Web pages in order of priority and according to the form style (display coordinates, display form or/and form size) stored in the storage section 114 . the

The control section 117 is mainly composed of a microcomputer, and provides control over the entire portable terminal 110 . For example, the control section 117 allows the web page acquisition section 111 to perform wireless exchange of various types of information, controls display of information on the display section 116, performs processing in response to information input at the operation section 115, and provides access related to the storage section 114. control. the

The control section 117 compares the newly acquired webpage information with the webpage information stored in the storage section 114, and when there is an updated (changed) element, displays and highlights the updated section at a predetermined position. Also, when there are a plurality of elements to be updated, the control section 117 regards the update of these elements as an update of one element so as not to regard a change in the number as an update. Furthermore, the element determined to be updated first on a predetermined Web page is considered to have the highest priority. the

When the number of changed elements is greater than the predetermined count, the control section 117 does not perform an operation of displaying the updated element at a predetermined position. the

In addition, after displaying the Web page information on the display section 116, the control section 117 switches the selected candidates in order of priority levels according to a user instruction input through the operation section 115, and determines the display position of the candidates. the

The control section 117 also calculates the scroll distance required to display the element at a predetermined position, and displays the element on the display section 116 at a position separated from the initial position by the acquired scroll distance. the

The control section 117 regards the element having the highest priority as the first element satisfying the priority condition on the determined predetermined Web page. In addition, the control section 117 switches the display of a predetermined Web page to display an element with the highest priority and an element with a low priority on the screen of the display section 116 . In addition, the control section 117 controls the display on the display section 116 so that the state of moving the display position to the next position is virtually presented using animation. the

When a predetermined number or more of updated parts are presented on the Web page, the control section 117 assumes that the related Web page is refreshed and does not perform initial scrolling to display the updated parts. In addition, as a display operation, the entire Web page is displayed in a reduced size so that the position of the updated portion can be indicated, and the display position is changed so that the updated portion selected by the user can be displayed at the original magnification. When there is no updated part, a notification to that effect is displayed on the display part 116 using an icon or a message. When Web pages acquired in the past are compared instead of being stored in the Web page storage section 112, a notice to that effect is displayed on the display section 116 using an icon or a message. In addition, for comparison of Web pages, when a link to a URL (Uniform Resource Locator) of a domain different from the Web page currently being browsed is specified for an updated part, the control section 117 does not regard the part as an updated part detection. the

The initial Web page display operation will be described below with reference to FIG. 2 . the

FIG. 2 is a flowchart illustrating an initial Web page display operation performed by the portable terminal 110 according to the first embodiment. the

First, in step ST101, a Web page to be displayed is acquired by the Web page acquisition section 111. the

In step ST102, the information stored in the web page storage section 113 is searched for a Web page having the same URL as the acquired Web page. the

In step ST103, if no Web page having the same URL as the acquired Web page is found in the Web page storage section 113 in step ST102, program control proceeds to step ST104. If such a Web page appears, program control moves to step ST105. the

In step ST104, a message or an icon is displayed on the display section 116, indicating that the process of determining whether there is an updated part cannot be performed since there is no Web page acquired in the past to be compared. the

In step ST105 , the control section 117 detects the updated section, and stores the information of the updated section in the storage section 114 . the

In step ST106, if no updated portion is detected in the process of step ST105, program control proceeds to step ST107. If an updated portion is detected, program control proceeds to step ST108. the

In step ST107, a message or an icon indicating that no updated portion appears on the acquired Web page is displayed on the display section 116. the

In step ST108 , a message or an icon indicating that an updated portion appears on the acquired Web page is displayed on the display section 116 .

In step ST109, a scrolling distance is specified for displaying the first updated portion at a predetermined position (for example, upper left, upper center, upper right, left, center, right, lower left, lower center, or lower right) on the display portion 116. the

Next, in step ST110, the web page is displayed on the display section 116 by scrolling the screen by a designated scroll distance. If no scroll distance is specified, the scroll distance is defined as 0 in both horizontal and vertical directions. When the scroll distance is equal to or less than the minimum value, or equal to or greater than the maximum value, scroll the screen to the minimum or maximum distance. In addition, the updated part of the Web page is displayed on the display part 116 and highlighted. the

At step ST111, the Web page acquired at step ST101 is stored in the web page storage section 112 together with URL information and information on the date and time at which the Web page was acquired. When a Web page of the URL already exists in the Web page storage section 112, the stored Web page is rewritten. the

When a new Web page cannot be stored because the available storage capacity in the page storage section 112 is insufficient, data that is not registered in the bookmark and whose access frequency is equal to or less than a predetermined level is sequentially erased from the oldest data in storage time until Web pages can be stored in the page storage unit 112 . the

If all web pages are registered in bookmarks, or the access frequency to these web pages is equal to or higher than a predetermined level, data is erased starting from the data with the oldest storage time. the

The operation performed when a display candidate change request is received is described below with reference to FIG. 3 . the

FIG. 3 is a flowchart illustrating an example of the operation of the first embodiment executed when a display candidate change request is issued by a user operation of the portable terminal 110 . This request is issued by the user after the initial display operation explained with reference to FIG. 2, and is executed accordingly. the

In step ST121, the user selects an updated portion stored in the storage section 114 during the initial Web page display operation. the

This can be performed using a method in which all updated parts are displayed on the display part 116 and the user selects one of the updated parts, or a method in which the user selects an updated part after or before the updated part selected just before starting. process. the

In step ST122, a scrolling distance is calculated for displaying the selected updated portion at a predetermined position. the

In step ST123, the web page is displayed on the display section 116 by scrolling the screen by the scroll distance acquired in step ST122. the

4A and 4B are schematic diagrams representing the entire layout before and after updating the sample Web page. the

The Web page in FIG. 4A is a Web page acquired in advance and stored in the Web page storage section 112 . the

FIG. 4B is a Web page currently acquired by the web page acquisition section 111 at the same URL as in FIG. 4A. the

The control section 117 compares the Web pages in FIGS. 4A and 4B, and detects an updated section. the

According to the example in Fig. 4A and 4B, add "NEW" after "notice (notice)", delete "NEW" after "link (link)", "bulletin board (bulletin board)" is changed into "BBS", Add "mail:abc@abc.co.jp" and change the update date. It should be noted that deleted characters are not considered to be updated parts. Also, the updated parts are displayed by being surrounded by a circle so that the user can easily recognize the parts. the

When updated parts appear at positions close to each other, these updated parts are regarded as one updated part. the

Therefore, an increase in the number of updated portions can be suppressed, and user operations can be reduced. the

Also, when a predetermined number or more of updated parts appear on the same web page, it is considered that the web page is being refreshed, and the initial display of the updated parts does not appear. the

In the first embodiment, when a link to a URL of a domain different from the Web page currently being browsed is specified for an updated portion, the updated portion is not regarded as a target to be detected. the

Portions on frequently updated Web pages are often linked to external information, such as advertisements, that are not important to many users. The above function is used to suppress update notifications for less important information. the

Furthermore, in the first embodiment, when a character string consisting of numerals is updated to a character string consisting of different numerals, the character string is not detected as an updated part. the

Only when numbers are updated, and these numbers belong to less important information such as access count or web page update date information, update of only numbers is not detected in order to suppress an increase in the number of updated parts. the

5A and 5B are diagrams showing a display example of the prior art and a display example of the first embodiment at the time of browsing the web page in FIG. 4B. the

FIG. 5A shows a display example of the prior art, in which the upper left portion in FIG. 4B is displayed. FIG. 5B shows a display example of the first embodiment, and the updated portion (“NEW” portion) that appears for the first time is displayed in the center of the display portion 116. the

6A and 6B are diagrams showing display examples of lists of updated parts in the first embodiment. the

When multiple updated parts appear on a single Web page, as shown in FIG. 6A, the position of the updated part is indicated by reducing the size of the entire Web page and the user is allowed to select one of the displayed updated parts. the

When the user selects an updated portion to display, as shown in FIG. 6B, the screen is scrolled to display the selected updated portion at the original magnification. the

7A, 7B and 7C are diagrams showing display examples of presence/absence update according to the first embodiment. the

In this instance, an icon is displayed in the picture area to inform the user of the presence/absence of an update. An icon indicating that an update has occurred is displayed in the example of FIG. 7A, and an icon indicating that an update has not occurred is displayed in the example of FIG. 7B. In addition, in the example of FIG. 7C , an icon is displayed when no cache of the target Web page appears in the Web page storage section 112 and the determination process cannot be started. the

Fig. 8 is a diagram showing an example of movement of a display portion using animation according to the first embodiment. the

Since the screen is gradually scrolled from the first display position indicated by the broken line to the display position indicated by the solid line, the user can easily recognize the position of the currently displayed screen-related Web page. the

9A and 9B are schematic diagrams of an example of processing for detecting an updated portion of the first embodiment. the

In this case, the HTML source of the Web page in FIGS. 4A and 4B is shown in FIGS. 9A and 9B. the

During the preprocessing of comparing the updated parts in the first embodiment, comments, tags, return codes and null codes are removed from the source codes of the two Web pages to be compared. Then, a matching process of the two source codes is performed to obtain corresponding elements. the

Matches against normal strings for each character, but treats tokens as individual elements that cannot be split. the

In the example of FIG. 9, through the matching process, it is found that the tag <imgsrc="new.GIF"> is added after the update is performed. the

When a normal character is deleted after an update, it is not detected as part of the update; however, if a mark is added, changed, or deleted, the extent of the range affected by that mark is considered part of the update. the

Also, for images, when the update dates of two image files are compared different, the entire image is considered to be the updated part even if the title of the image is not updated. the

In FIGS. 9A and 9B, at the source, the image "top.jpg" is specified before "new.GIF"; however, according to the first embodiment, "new .GIF" and check the size information for that image. the

10A, 10B and 10C are diagrams showing movement of a display position. the

In Figures 10A, 10B and 10C, the display positions of the first, second and third updated parts are shown, and after the Web page is acquired, the screen moves to the screen in Figure 10A, or moves automatically, or is moved by user action. the

According to this first embodiment, the display position in FIG. 10A can be sequentially switched to the display positions in FIGS. 10B and 10C either by user operation or by using the automatic display position switching function. the

At this time, a specific display appears on the display section 116 in order to inform the user of the existence of the next priority display candidate. After displaying the most recently updated part, the display position is returned to the position of the first updated part by switching operation. the

In addition, when the user performs a confirmation operation, the highlighting of the updated part at the current display position is turned off, or the display for notifying the user of the existence of the next updated part is deleted, and the screen returns to the normal Web browsing screen. the

As described above, according to the present invention, the portable terminal 110 includes the web page storage part 112 in which the Web page is temporarily stored while the Web page is browsed. Therefore, when the same Web page is browsed next time, the control section 117 compares the Web page with the pre-stored content of the Web page, and moves the display range of the Web page so as to display the updated part at a predetermined position on the display section 116 . The following effects can be obtained. the

Even with an information device having only a small display portion such as a portable, the user does not have to repeat scrolling operations to browse Web pages, and can quickly display a portion including information that the user wants to be displayed preferentially on the display portion. the

(second embodiment)

FIG. 11 is a block diagram showing a portable terminal employing a display device according to a second embodiment of the present invention.

The portable terminal 210 of the second embodiment is a device in which browser software is installed so as to be able to browse Web pages. Although the portable terminal 210 has only a small display portion, the device preferentially displays a portion including important information of the user on the display portion without requiring the user to perform a scrolling operation. the

The portable terminal 210 may be, for example, a cellular phone or a PDA. FIG. 11 depicts the functions performed by the display device as a device for browsing Web pages according to the present invention. For the second embodiment, the related operations when the display device is used as the browsing device are mainly described. the

A Web page is a file distributed through the Internet using WWW (World Wide Web). That is, a Web page is a set of data simultaneously displayed by a Web browser, and is composed of text data, layout information prepared using HTML, and images, sounds, and moving pictures embedded in documents. the

For individual element(s) included on each Web page, the portable terminal 210 in the second embodiment can specify priority levels and priority conditions including conditions for specifying elements. One function of the portable terminal 210 is to display the highest priority element at a predetermined position. the

In addition, it is assumed that the assigned priority level will be changed according to the Web page, that is, the specified element will not appear on the page, or the specified element will have low priority on one page, but will have the highest priority on another page. Priority, the portable terminal 210 displays an element on a predetermined web page having the highest priority among all elements satisfying the priority condition at a predetermined position. the

In a second embodiment, elements are strings, images, tags, data files, controls (text boxes) included in the source of a web page. the

Information about an element includes an overview of the element and its details. the

The priority condition includes element type, element information, priority (priority level), URL (Uniform Resource Locator), information on the time of browsing the Web page, and coordinates of the entire Web page. In the second embodiment, the coordinates can be specified by the user, and the display position can be indicated when the display of the Web page ends. the

Also, in the second embodiment, a function of the device is to designate positions and elements to be displayed, so that the center, upper left and upper right positions on the display screen can be set as display positions. the

In addition, the portable terminal 210 of the second embodiment includes: using address information, the function of obtaining Web page information including a plurality of elements through a communication network; including multiple pairs of address designation information for address information and for designation and address designation information designation information related to one element; and a function of extracting designation information related to address designation information designating address information of the acquired Web page information from the priority information; searching the acquired Web page information to find the one designated by the extracted designation information the function of the element; and the function of displaying the searched element at a predetermined position. the

The URL described above can be adopted as address information or address specifying information. A description system representing the location of information resources such as files or images appearing on the Internet is employed as a URL, and corresponds to address information on the Internet. A URL is formed from the information type, the port encoding of the server name, and the folder and file names. Specifically, the URL is written as "access means://hostname.domain name[:port name]/path/filename", using http as the access means. the

For the portable terminal 210, the priority information includes pairs of address designation information and designation information for designating an element, and priority level information indicating a priority level of display related to the address designation information and/or designation information. A plurality of specifying information that coincides with the address specifying information can be extracted from the priority information. The address specifying information is used to specify the address information of the obtained Web page information. When the plurality of specified information is extracted, a searchable element having the highest priority rank among the plurality of elements related to the plurality of extracted specified information is displayed at a predetermined position. the

The priority level information includes priority, priority level, and priority level associated with predetermined elements. the

In addition, according to the second embodiment, address specifying information includes a predetermined character string. When the character string for the address information of the acquired Web page information includes a character string preparing address designation information in the priority information, the portable terminal 210 extracts designation information related to the address designation information in the priority information. Then, the element specified by the extracted specified information is searched through the acquired Web page information, and displayed at a predetermined position. the

That is, in the second embodiment, priority conditions are applied to addresses that commonly use the upper part, and only the lower part is different for URLs that have the same domain name and path name, for example. the

The portable terminal 210 in the second embodiment has functions of calculating a required scrolling distance for displaying an element at a predetermined position, and displaying the element at a position separated from the calculated scrolling distance at the initial position. the

In the second embodiment, the portable terminal 210 also has a function of displaying an element having the highest priority at a predetermined position when starting up the browser. This is accomplished by considering the first element on a predetermined Web page that is determined to satisfy the priority condition to be the element with the highest priority. the

Furthermore, in the second embodiment, the portable terminal 210 has a function of switching the display on a predetermined Web page so as to display an element with the highest priority, and to display an element with a low priority at a predetermined position. That is, user operations with the portable terminal 210 sequentially change the display to elements of low priority levels. the

As described above, the portable terminal 210 has a function of switching the priority order of display; however, this display changing operation may be performed using user manipulation, or may be automatically performed after a predetermined period of time has elapsed.

In addition, the portable terminal 210 has a function of virtually giving a moving state from one display position to the next display position using animation. the

The structure and function of each part of the portable terminal 210 according to the second embodiment, the initial display operation performed on a Web page, the operation performed when receiving a display candidate switching request, screen examples for setting priority conditions, and browsing a Web page will be described below. An example of the screen, an example of the process of using animation when moving the display position, an example of the process of detecting priority conditions, and a process of generating a condition table are explained. the

As shown in FIG. 11 , the portable terminal 210 includes: a webpage acquisition part 211 , a webpage analysis part 212 , a timer 213 , a storage part 214 , an operation part 215 , a display part 216 and a control part 217 . the

The web page acquisition section 211 has a function of acquiring a Web page through, for example, a communication network using a communication function, and/or a function of acquiring a Web page from a recording device (not shown). the

The web page information acquired by the web page acquisition section 211 is output to the web page analysis section 212 . the

If the portable terminal 210 is a cellular phone, the web page acquisition section 211 performs radio communication using a communication section through a base station (not shown), such as dialing a telephone number or sending or receiving e-mail. the

The web page analysis section 212 analyzes the web page acquired by the web page acquisition section 211, acquires and extracts not only the types of elements included in the web page, but also the positions and sizes of elements on the web page, and outputs the result to the control section 217. the

The timer 213 measures the current elapsed time. The control section 217 refers to the time acquired by the timer 213 . the

The storage section 214 stores priority conditions specified by the user using the operation section 215, for example. the

The storage section 214 includes a nonvolatile memory such as EEPROM, and is used to store a control program for performing voice communication or sending or receiving e-mail, an Internet browser, message data, and names and telephone numbers registered therein. address book.

In the storage section 214, in relation to the URL object, the element type extracted from the Web page message, the information related to the element and priority (priority level), and the information indicating the time to browse the Web page and the Web page are stored by the control section 217. The coordinates of the web page. the

When the portable terminal 210 is a cellular phone, the operation section 215 includes a plurality of ten-key numeric keypads, and an end (voice end)/power key and a start (dial) key. When the user operates these keys provided for the operation section 215 , an instruction input by the user to change the priority condition or priority, or position information designated by the user for displaying elements on the display section 216 is output to the control section 217 . the

The display section 216 includes a display device such as a liquid crystal display device (LCD), and displays electronic mail received as text or various types of text data stored in the storage section 214 under the control of the control section 217 . the

In addition, under the control of the control section 217, the display section 216 displays the acquired Web pages in order of priority and according to the display style (display coordinates, display form or/and form size) stored in the storage section 214. . the

The control section 217 is mainly composed of a microcomputer, and provides control over the entire portable terminal 210 . The control section 217 allows the web page acquisition section 211 to perform wireless exchange of various types of information, controls display of information on the display section 216, performs processing in response to information input at the operation section 215, and provides access control related to the storage section 214, for example. the

The control section 217 compares the priority conditions stored in the storage section 214 with the information acquired for the Web page extracted by the web page analysis section 212 and the time information acquired by the timer 213, and determines the part matching the specified condition as a priority display candidate. Furthermore, the control section 217 always adds the condition "coordinate (0, 0)" as a candidate of the lowest priority. the

When there are a plurality of candidates matching the prescribed condition, the control section 217 assigns higher priority to the candidate detected first. the

At the initial display time, the control section 217 selects the highest priority candidate, and determines the display position of the candidate on the display section 216 . the

In addition, after displaying the Web page information on the display section 216, the control section 217 changes the priority order of the selected candidates when the user manipulates the operation section 215, and determines the display positions of these candidates. the

The control section 217 calculates the scrolling distance required to display the element at a predetermined position, and displays the relevant element on the display section 216 at a position whose initial position is away from the scrolling distance obtained by the calculation. the

In addition, the control section 217 has a function of displaying an element having the highest priority at a predetermined position when the browser is started. In addition, the first element of the predetermined Web page determined to satisfy the priority condition is taken as the element with the highest priority. the

Furthermore, the control section 217 changes the display so that an element with the highest priority is displayed on a predetermined Web page and an element with a low priority is displayed at a predetermined position on the screen of the display section. the

Furthermore, the control section 217 controls the display on the display section 216 with animation so that the virtual representation moves from one display position to the next. the

The initial operation of displaying a Web page will be described below with reference to FIG. 12 . the

FIG. 12 is a flowchart illustrating an initial Web page display operation performed by the portable terminal 210 according to the second embodiment. the

First, in step ST201, for the Web page acquired and displayed by the web page acquisition section 211, the web page analysis section 212 analyzes and extracts elements such as character strings, images, and controls appearing on the web page, and the information of these elements (such as , position, size, presence/absence of links and font information). The analysis result is transmitted to the control section 217 . the

Then, in step ST202, the control section 217 compares the web page analysis result acquired by the web page analysis section 212 with the priority conditions stored in the storage section 214, and lists elements satisfying the conditions as display candidates. the

In step ST203, the control section 217 registers all the candidates in the storage section 214 so as to change the display candidates after displaying them once. Through this process, when the candidate is to be changed, it is not necessary to repeatedly perform the process for comparison with the condition. It should be noted that when the Web page to be displayed is changed, the contents registered in the storage section 214 are erased. the

In step ST204, the control section 217 selects a candidate with the highest priority from the enumerated candidates. the

In step ST205, the control section 217 calculates the volume required to display the selected candidate at a predetermined position (for example, sitting up, upper center, upper right, left, center, right, lower left, lower center, or lower right) on the display section 216. moving distance. the

Since the position and size of the element can always be known by the analysis performed at step ST1, an appropriate scrolling distance is obtained based on the information on the width and height of the display portion 216. the

In step ST206 , the control section 217 scrolls the screen and the scroll distance acquired in step ST205 , and displays the selected candidate on the display section 216 . When the scrolling distance is equal to or less than a predetermined minimum value, or equal to or greater than a predetermined maximum value, the screen is scrolled toward the minimum defined distance and the maximum defined distance. the

The operation performed when a display candidate change request is received is described below with reference to FIG. 13 . the

FIG. 13 is a flowchart of an example operation of the second embodiment performed when a display candidate change request is issued in response to user manipulation of the portable terminal 210 . This request is issued by the user after the initial display operation explained with reference to FIG. 12 is performed. the

In step ST211, the user is allowed to select one of the display candidates registered in the storage section 214 when initially displaying the Web page. This process may be performed by displaying all the candidates on the display section 216 and allowing the user to select one from the candidates, or allowing the user to select among priority candidates one rank higher or one rank lower than the candidate just selected method to perform the process. the

In step ST212, like step ST205 in FIG. 12, the control section 217 calculates a scrolling distance required to display the selected candidate at a predetermined position. the

In step ST213, like step ST206 in FIG. 12, the control section 217 scrolls the screen by the scroll distance acquired in step ST212. the

An example of a procedure for setting priority conditions according to display screens will be described below with reference to FIGS. 14A to 14D. the

14A to 14D are diagrams showing examples of screens displayed on the display section 216 on which the control section 217 of the second embodiment allows the user to designate priority conditions (display conditions) stored in the storage section 214. the

In order to set the priority condition, as shown in FIG. 14A, the user manipulates the operation section 215 to input a URL to which the condition to be specified is to be applied. This URL is included as the initial value of this item just before the Web page is to be displayed. the

Also, in the second embodiment, it is possible to select to impose a condition on all URLs instead of specifying a specific URL, and to select to manually input a URL. Furthermore, by operating the manipulation section 215, it is possible to designate an object to be preferentially displayed as a condition from these elements as character strings, images/moving pictures, controls (such as buttons, radio buttons, check buttons, and text boxes), and coordinates. In addition, the display position of the selected element on the display section 216 is specified by manipulating the operation section 215 . You can also specify a time period during which the condition is applied. the

When "character string" is specified as the condition in FIG. 14A, the screen example in FIG. 14B is displayed to set the dialing condition. the

In the example of FIG. 14B, character strings including "topics" are considered as priority display conditions. On this screen, conditions can be specified in terms of character strings, styles of character strings (including font, size, and color), and presence/absence of links. the

The screen example of Fig. 14C is displayed to set the priority of the specified condition. the

In the example of FIG. 14C, two general conditions appear, and an intermediate level between the two general conditions is selected as the priority level of the specified condition. the

The screen shown in FIG. 14D is displayed after assigning the second priority to the condition on the screen in FIG. 14C. Inserts the currently specified condition into the second priority and moves the previous second condition to the third priority. the

At the end of the processing sequence shown in FIGS. 14A to 14D , the designated priority display condition is registered in the priority condition storage section, and the candidate detectors of the control section 217 refer to the priority during the display position determination operation performed by the control section 217. right to display the conditions. the

The operation of setting display conditions according to the Web page currently being displayed will be described below with reference to FIGS. 15A to 15F. the

15A to 15F are diagrams showing an example of a screen displayed on the display section 216, on which the control section 217 of the second embodiment allows the user to specify the priority according to the currently displayed Web page stored in the storage section 214. Conditions (display conditions). the

In the screen example of FIG. 15A, a Web page is browsed. The screen example in FIG. 15B is displayed when the user calls out the condition setting menu while browsing the Web page. the

On this screen, the user manipulates the operation section 215 to select an element designated as a priority condition. the

On the screen of FIG. 15C, the element selected in FIG. 15B ("string" in this case) is also selected on the Web page currently being displayed. However, when "coordinates" is selected in FIG. 15B, the screen in FIG. 15C is omitted, and the coordinate position of the upper left point is indicated on the currently displayed screen. the

The display position on the screen is designated with the screen example among Fig. 15D, conditions such as browsing time zone conditions and the like. the

On the screen of Fig. 15E, priority levels are set for specified conditions. On the screen of Fig. 15F, the priority of the condition to which the priority is assigned is displayed. the

The registered conditions are stored in the URL-related storage section 214, and become valid only when a web page including the URL is displayed. the

It should be noted that after registration, general conditions can also be edited using the method shown in FIGS. 14A to 14D. the

The following describes the normal display screen and the display screen provided by the display section 216 when browsing a Web page in the second embodiment. the

Fig. 16 is a diagram showing an example of the layout of the entire Web page and a normal display screen. the

17A to 17D are diagrams showing examples of display screens provided by the display section 216 of the second embodiment when browsing Web pages. the

In FIG. 16, a box indicated by a dotted line represents an initial display range of a general (normal) display method in which no enlargement or reduction of the image size is performed. the

According to this normal display method, the upper left portion is displayed first; however, in many cases, the upper left portion is blank, and the user is required to perform a scrolling operation. the

In FIG. 17A , candidates matching the "character string of 'topics'" priority display condition are preferentially displayed on the screen. the

Since the upper left display part is specified, the screen is scrolled so that the character string of "topics" is displayed on the upper left part. the

In the example of FIG. 17B , candidates matching the display condition "image" are displayed in the center of the screen. the

When "image" is specified as the display condition, the control section 217 actually searches for tags <img...> included in the HTML file, and the Web page is written in the HTML file. The control section 217 determines whether the file name specified in the tag matches the condition. When the file name matches the condition, the screen is scrolled so that image data can be read while being displayed at a predetermined position. the

In the example of FIG. 17C , candidates matching the display condition "control (text box)" are displayed in the lower middle part of the screen. the

When "control" is specified as the condition, the control section 217 also searches for a tag <input . . . > in the HTML file, and determines whether the type of control included in the tag matches the condition.

In the example of FIG. 17D , candidates matching the display condition "coordinates (100, 100)" are displayed on the upper left portion on the screen. the

The process of moving the display position using animation will be described below with reference to FIG. 18 . the

Fig. 18 is a diagram showing an example of a procedure for moving a display position using animation according to the second embodiment. the

Since the screen is gradually scrolled from the initial display position A indicated by the dotted line in FIG. 18 to the display position B indicated by the solid line in FIG. 18 , the user can easily recognize the position of the currently displayed screen related to the Web page. the

An example of a procedure for detecting a priority condition will now be described with reference to FIGS. 19A to 19C. the

19A to 19C are schematic views of an example of a procedure for detecting a priority condition according to the second embodiment. the

As shown in FIG. 19A, assume that the HTML source code of the Web page is displayed. the

The screen in FIG. 19B is displayed when an image having a file name "mypic.jpg" displayed at the center of the screen is designated. In the HTML source code in FIG. 19A, the image "ABC.jpg" is specified before the image "mypic.jpg"; however, in the second embodiment, the image matching the condition is read before "ABC.jpg" "mypic.jpg" and examine the image's size information. the

When the display of the text box in the lower part of the screen is specified, the screen in FIG. 19C is displayed. the

Search the source code for "input" tags based on the type of information included in the tag to determine the type of text box or button. the

The process of generating the condition table will be described below with reference to FIGS. 20A, 20B, 21A and 21B. the

20A, 20B, 21A and 21B are diagrams illustrating a condition table generation process according to the second embodiment. the

This process is considered as an example of the generation process performed in FIG. 16 when browsing the Web page at URL http://www.aaa.jp at 18:00.

The table in FIG. 20A represents all the conditions registered in the storage section 214 by the control section 217. the

The table includes "priority", "URL", "time zone", "element (condition)", "condition data", and "(display) location" as columns. the

For example, for the first priority, URL " www.aaa.jp ", time zone "none", element "image", condition data "filename mypic.jpg", and display position "central" are registered.

For the second priority, URL "none", time zone "12:00 to 19:00", element "character string", condition data "news" and display position "upper left" are registered. the

For the third priority, URL "none", time zone "none", element "character string", condition data "subject" and display position "upper left" are registered. the

For the fourth priority, URL "none", time zone "none", element "character string", condition data "today's fortune" and display position "upper left" are registered. the

For the fifth priority, URL " www.aaa.jp ", time zone "5:00 to 9:00", element "control", condition data "button" and display position "bottom right" are registered.

For the sixth priority, URL " www.aaa.jp ", time zone "none", element "control", condition data "photograph" and display position "upper center" are registered.

For the seventh priority, URL "none", time zone "20:00 to 23:00", element "image", condition data "extension.'gif'", and display position "center" are registered. the

For the eighth priority, URL " www.aaa.jp ", time zone "17:00 to 20:00", element "control", condition data "text box" and display position "middle lower" are registered.

For the ninth priority, URL " www.ccc.ne.jp ", time zone "none", element "control", condition data "text box", and display position "left" are registered.

For the tenth priority, URL "none", time zone "none", element "coordinates", condition data "0,0" and display position "upper left" are registered. the

The table in FIG. 20B is a table generated by filtering the items in the table in FIG. 20A according to conditions and condition data. On storing these entries, the following results were obtained. the

For the first priority, URL " www.aaa.jp ", time zone "none", element "image", condition data "filename mypic.jpg", and display position "center" are registered.

For the second priority, URL "none", time zone "none", element "character string", condition data "subject" and display position "upper left" are registered. the

For the third priority, URL " www.aaa.jp ", time zone "5:00 to 9:00", element "control", condition data "button" and display position "bottom right" are registered.

For the fourth priority, URL " www.bbb.co.jp ", time zone "none", element "character string", condition data "photograph" and display position "upper center" are registered.

For the fifth priority, URL " www.aaa.jp ", time zone "17:00 to 20:00", element "control", condition data "text box" and display position "middle lower" are registered.

For the sixth priority, URL " www.ccc.ne.jp ", time zone "none", element "control", condition data "text box", and display position "left" are registered.

For the seventh priority, URL "none", time zone "none", element "coordinates", condition data "0,0" and display position "upper left" are registered. the

The table in FIG. 21A is obtained by eliminating the conditions according to the URL that does not match the URL of the Web page to be displayed in FIG. 20B according to the specified URL, and then storing these items so that the priority according to the specified URL is higher than the condition according to the non-specified URL. table generated by priority. That is, the table in FIG. 21A is acquired by filtering out the items in FIG. 21B according to the URL, and stores these items. For example, a case of browsing " www.ccc.ne.jp " is given. As a result of storing these items, the following are obtained.

For the first priority, URL " www.aaa.jp ", time zone "none", element "image", condition data "filename mypic.jpg", and display position "center" are registered.

For the second priority, URL " www.aaa.jp ", time zone "5:00 to 9:00", element "control", condition data "button" and display position "bottom right" are registered.

For the third priority, URL " www.aaa.jp ", time zone "17:00 to 20:00", element "control", condition data "text box" and display position "middle lower" are registered.

For the fourth priority, URL "none", time zone "none", element "character string", condition data "subject" and display position "upper left" are registered. the

For the fifth priority, URL "none", time zone "none", element "coordinates", condition data "0,0" and display position "upper left" are registered. the

The table in Figure 21B is the table produced by eliminating the condition that the time zone does not match the browsing time specified in Figure 21A, and by storing the entries so that the priority of the condition according to the specified time zone is higher than the priority of the condition according to the unspecified time zone . The generated table is registered in the storage section 214 as a table in which the final priority display position is entered. the

The contents of the final registration table are as follows. the

For the first priority, URL " www.aaa.jp ", time zone "17:00 to 20:00", element "control", condition data "text box" and display position "middle lower" are registered.

For the second priority, URL " www.aaa.jp ", time zone "none", element "image", condition data "filename mypic.jpg", and display position "center" are registered.

For the third priority, URL "none", time zone "none", element "character string", condition data "subject" and display position "bottom left" are registered.

For the fourth priority, URL "none", time zone "none", element "coordinates", condition data "0,0" and display position "upper left" are registered. the

22A and 22B are diagrams showing the final watch movement display positions acquired according to FIGS. 20A, 21B, 21A and 21B. the

FIG. 22A shows the display position of the first priority, which is taken as the initial display position of the current Web page. The display positions shown in FIGS. 22B, 22C and 22D are the display positions of the second priority, the third priority and the fourth priority. the

In the second embodiment, it is also possible to sequentially move the display position shown in FIG. 22A to the display positions shown in FIGS. 22B, 22C and 22D by user manipulation or an automatic display position switching function. the

At this time, a specific expression is provided on the display portion 216 in order to inform the user that the next candidate to be preferentially displayed appears. After displaying the candidate with the lowest priority, the display position is returned to the display position of the first priority by the switching function. the

As described above, according to the present invention, priority is given to conditions of display positions (including positions of character strings, images, text boxes, and buttons or coordinate points) in a Web page.
