  By the way, with the spread of mobile terminals such as mobile phones and PDAs in recent years, cases of browsing web pages on the Internet using mobile terminals are increasing.

  Most of these Web pages are designed to be viewed on a device equipped with a large display device such as a personal computer, and many are not suitable for viewing on a mobile terminal having only a small display unit. .

  Further, in a small portable terminal such as a mobile phone, input means are also limited. Although it is assumed that a personal computer has a pointing device such as a mouse as an input device, many mobile phone terminals perform operations when browsing Web pages with a small number of keys.

  As a method for browsing a large Web page or image on a small screen, there is a method in which the entire Web page is reduced and displayed so that the entire width of the page or the entire page fits in the display unit.

  However, many web pages are considerably larger than the display part of a portable terminal.

  Therefore, in the above browsing method, if the image is reduced so that it can be accommodated in the display unit, the reduction rate increases, and characters on the page may not be readable.

  When a Web page created for a personal computer or the like is viewed on a portable terminal that has only a small display device, in many cases, an insignificant part (mostly in the upper left) is displayed in the initial state and must be scrolled. There are many things that must be done.

  Therefore, when browsing a large-sized web page with a mobile terminal, in order to browse information outside the display range of the display unit, it is necessary to press the key many times to scroll, forcing the user to perform troublesome operations. There are disadvantages.

  Therefore, it is conceivable to adopt a method of preferentially displaying predetermined items according to the priority order as described above.

  However, since the display technology according to the priority order described above takes a past history and assigns a priority order based on the number of selections, access frequency, etc., the highly important element that the user really needs at that time is displayed. However, it is not always possible to display an element with the next highest priority when there is no element satisfying the highest priority condition.

  Moreover, even if the highest priority is given on a certain page, the element may not exist on other pages, and even if the priority is low on some pages, it may be given the highest priority on other pages. With this technology, priorities cannot be set according to the situation, and these requests cannot be fully met.

  In other words, in the conventional technology, information that is highly important to the user cannot be displayed in the initial state, and it is necessary to impair visibility, or to perform a troublesome scrolling operation, so that necessary information can be displayed quickly. There is a disadvantage that you can not.

  An object of the present invention is to provide a display device capable of quickly displaying necessary information without impairing visibility or performing a troublesome scrolling operation.

  In order to achieve the above object, an aspect of the present invention provides a display unit, an acquisition unit that acquires predetermined Web page information, a storage unit that stores at least a part of the Web page information acquired by the acquisition unit, At least one of the Web page information newly acquired by the acquisition unit and the Web page information stored by the storage unit and acquired from the same address as the newly acquired Web page information. And when there are a plurality of changed elements, a control means for displaying a reduced display of the entire Web page indicating the positions of the changed elements on the display means as an initial display of the Web page And have.

  Preferably, it further has an operation means, and the control means displays the changed element selected by the operation means on the display means at the original magnification after the initial display.

  According to the present invention, it is possible to provide a display device that can quickly display necessary information without impairing visibility or performing a troublesome scrolling operation.

  Hereinafter, the configuration and function of each part of the mobile terminal 10 according to the present embodiment, the initial display operation of the Web page, the operation at the time of the display candidate switching request, the example of the Web page layout and update location, the initial table at the time of browsing the Web page A display example, an update location list display example, an update presence / absence display example, an animation display position movement example, an update location detection example, and a display position transition will be described in order.

  As illustrated in FIG. 1, the mobile terminal 10 includes a page acquisition unit 11, a page storage unit 12, a clock unit 13, a storage unit 14, an operation unit 15, a display unit 16, and a control unit 17.

  The page acquisition unit 11 has a function of acquiring a Web page through a communication network using a communication function and / or a function of acquiring a Web page from a recording device (not shown).

  The page acquisition unit 11 outputs the acquired web page information to the control unit 17.

  When the mobile terminal 10 is a mobile phone, the page income unit 11 performs a wireless communication operation via a base station (not shown), for example, a call operation for a telephone number or an e-mail transmission / reception operation, by a communication function.

  The page storage unit 12 stores the page acquired by the page acquisition unit 11 and information associated with the page by the control unit 17.

  The timer 13 measures the current date and time. The date and time measured by the time measuring unit 13 are referred to by the control unit 17.

  In the storage unit 14, for example, updated part information of a Web page is stored by the control unit 17.

  The storage unit 14 includes a nonvolatile memory such as an EEPROM, and stores, for example, a control program for sending and receiving calls and mails, an Internet browser, message data, an address book in which names and telephone numbers are registered.

  In the storage unit 14, the element type extracted from the Web page information, the element information, the priority (priority), the time information when browsing the Web page, the coordinate points in the entire Web page, and the like are associated with the object in the URL. Stored in the form by the control unit 17.

  The operation unit 15 has a plurality of numeric keys corresponding to numbers, etc., and in the case of a cellular phone, an end (end call) / power key, a start (call) key, and these keys are operated by the user. The control unit 17 outputs input information such as a priority switching instruction from the user and a position at which the element is displayed on the display unit 16.

  The display unit 16 includes a display device such as a liquid crystal display (LCD), and displays the text of the received e-mail and various text data stored in the storage unit 14 under the control of the control unit 17.

  Further, the display unit 16 converts the acquired Web page information into display rules (display coordinates, display format, and / or display size) stored in the storage unit 14, for example, in the priority order in accordance with the control of the control unit 17. Display in the format that you followed.

  The control unit 17 is configured mainly with a microcomputer, and controls the entire mobile terminal 10. For example, the control unit 17 performs wireless transmission / reception control of various information in the page acquisition unit 11, display control of information on the display unit 16, processing according to input information of the operation unit 15, access control to the storage unit 14, and the like. Do.

  The control unit 17 compares the newly acquired page information with the page information stored in the storage 14, and when there is an updated (changed) element, the updated element is highlighted and displayed at a predetermined position. . Further, when there are a plurality of updated elements, the plurality of updated elements are treated as one update, and a change in a number (column) can be regarded as not an update. In addition, the determined element that is updated first in a predetermined Web page is set as the element having the highest priority.

  When there are more updated elements than the predetermined number, the control unit 10 does not perform an operation of displaying the updated elements at a predetermined position.

  In addition, after the Web page information is displayed on the display unit 16, the control unit 17 switches the selection candidates in order of priority by the user's operation of the operation unit 15 and determines the display position.

  The control unit 17 calculates a scroll amount necessary for displaying the element at a predetermined position, and displays the updated element on the display unit 16 at a position moved by the calculated scroll amount from the initial position. .

  The control unit 17 sets the element that is determined to satisfy the priority condition first in the predetermined Web page as the element having the highest priority. The control unit 17 switches the display so that the element with the highest priority is displayed on the predetermined Web page and the element with the lower priority is displayed at a predetermined position on the display screen of the display unit 16. Further, the control unit 17 controls the display of the display unit 16 so as to visually show the movement to the next display position by animation.

  If there are more than a specified number of update locations in the Web page, the control unit 17 determines that the update location has been renewed, and does not perform initial scrolling to display the update location. Further, in the display operation, the entire Web page is reduced and displayed to indicate the position of the update location, and the display position is switched so that the update location selected by the user is displayed at the original magnification. If there is no update location, an icon or message indicating that fact is displayed on the display unit 16, and if a past Web page to be compared does not exist in the page storage unit 12, this is indicated. An icon or message is displayed on the display unit 16. In addition, when comparing the Web pages, the control unit 17 updates the updated part when a link to a URL (Uniform Resource Locator) of a domain different from the Web page being browsed is set in the updated part. Does not detect as.

  Next, the Web page initial display operation will be described with reference to FIG.

  FIG. 2 is a flowchart for explaining the initial display operation of the Web page in the mobile terminal 10 according to the present embodiment.

  First, in step ST1, the page acquisition unit 11 acquires a Web page to be displayed.

  In step ST2, a Web page having the same URL as the acquired Web page is searched from the storage information of the page storage unit 13.

  In step ST3, if a web page having the same URL as the acquired web page does not exist in the page storage unit 13 in step ST2, the process proceeds to step ST4. If present, the process proceeds to step ST5.

  In step ST4, since there is no past Web page to be compared, a message or icon indicating that the update location cannot be determined is displayed on the display unit 16.

  In step ST <b> 5, an update location is detected by the control unit 17, and information on the update location is stored in the storage unit 14.

  In step ST6, if an update location is not detected as a result of the process in step ST5, the process proceeds to step ST7, and if it is detected, the process proceeds to step ST8.

  In step ST7, a message or icon indicating that there is no update location in the acquired Web page is displayed on the display unit 16.

  In step ST8, a message or icon indicating that an update location exists in the acquired Web page is displayed on the display unit 16.

  In step ST9, a scroll amount for displaying the first update location at a predetermined position on the display unit (upper left, upper center, upper right, left, center, right, lower left, lower center, lower right, etc.) is set. .

  Next, in step ST10, the page is displayed on the display unit 16 by scrolling by the set scroll amount. If the scroll amount is not set, the scroll amount is set to 0 in both the horizontal direction and the vertical direction. If the scroll amount is less than the minimum value or greater than the maximum value, the scroll is limited to the minimum value and the maximum value, respectively. In addition, the update location in the Web page is highlighted and displayed on the display unit 16.

  In step ST11, the Web page acquired in step ST1 is stored in the page storage unit 12 together with the URL information and the acquired date / time information. If a Web page with the same URL exists in the page storage unit 12, it is overwritten and stored.

  In the case where the data capacity stored in the page storage unit 12 exceeds the specified value and cannot be newly stored, it is not registered in the bookmark until it can be stored, and the access frequency is below a certain value. Delete the data from the oldest stored time.

  When all pages are registered in the bookmark or the access frequency is a certain value or more, the oldest data stored in the page is deleted in order from the oldest data.

  Next, the operation at the time of a display candidate switching request will be described with reference to FIG.

  FIG. 3 is a flowchart for explaining an operation example at the time of a display candidate switching request by a user operation or the like in the mobile terminal 10 according to the present embodiment. This request is a request issued by a user operation after performing the initial display operation described with reference to FIG.

  In step ST21, the user is allowed to select one of the updated portions stored in the storage unit 14 when the Web page is initially displayed.

  This operation may be a method of displaying all update locations on the display unit and allowing the user to select one of them, or a method of selecting an update location next to or before the update location selected immediately before.

  In step ST22, a scroll amount for displaying the selected update location at a predetermined position is calculated.

  Next, in step ST23, the page is displayed on the display unit 16 by scrolling by the scroll amount obtained in step ST22.

  FIGS. 4A and 4B are diagrams showing the overall layout before and after updating the sample Web page.

  FIG. 4A shows a Web page stored in the page storage unit 12 when the previous page was acquired.

  FIG. 4B shows a Web page newly acquired by the page acquisition unit 11 with the same URL as that in FIG.

  The Web pages shown in FIG. 4A and FIG. 4B are compared in the control unit 17 to detect an update location.

  In the example in the figure, `` NEW '' is added after `` Notice '', `` NEW '' after `` Link '' is deleted, `` BBS '' is changed to `` BBS '', `` mail: abc@abc.co. jp "has been added and the update date has been changed. However, deleted characters are not updated. In addition, the update location is highlighted by enclosing it with a circle or the like so that it can be easily recognized by the user.

  When update locations exist at positions close to each other, these multiple update locations are treated as a single update location.

  Thereby, the increase in an update location can be suppressed and a user's operation amount can also be reduced.

  Also, if there are more than a certain number of update locations within the same page, the page is treated as being renewed, and the initial display of update locations is not performed.

  In the present embodiment, when a link to a URL of a domain different from the Web page being browsed is set at the updated location, the updated location is not detected.

  Often, frequently updated portions of a Web page are information linked to the outside such as advertisements, and such information is not very important for many users. This function is a function for suppressing the update notification of such less important information.

  In the present embodiment, when a character string composed of numbers is updated to a character string composed of other numbers, the character string is not detected as an update location.

  If only the numbers are updated, it is likely that the numbers are less important information such as access counters and page update dates, so updating only the numbers is updated to suppress the increase in the number of updates. Not detected as a point.

  5A and 5B are diagrams showing a conventional display example when browsing the Web page of FIG. 4 and a display example in the present embodiment.

  FIG. 5A shows a conventional display example, and the upper left part of FIG. 4B is displayed.

  On the other hand, FIG. 5B shows a display example in the present embodiment, in which the updated portion (“NEW” portion) that appears first is displayed in the center of the display unit.

  FIGS. 6A and 6B are diagrams showing a list display example of update locations in the present embodiment.

  When there are a plurality of update locations on one Web page, as shown in FIG. 6A, the entire Web page is displayed in a reduced size to indicate the location of the update location, and which update location is displayed to the user. Let

  When the determination operation is performed by the user, as shown in FIG. 6B, scrolling is performed so that the selected update location is displayed at the original magnification.

  FIGS. 7A, 7B, and 7C are diagrams illustrating display examples of whether or not there is an update in the present embodiment.

  In this example, an icon is displayed in the picto area to notify the user of whether or not there is an update. 7A is a display example when there is an update, FIG. 7B is a display example when there is no update, and FIG. 7C is a determination that the cache of the target Web page does not exist in the page storage unit. The example of a display when it is impossible is shown.

  FIG. 8 is a diagram illustrating an example of movement of the display position by animation in the present embodiment.

  By gradually scrolling from the initial display position indicated by the broken line in the figure to the display position after scrolling indicated by the solid line, it is easy for the user to understand where the displayed screen is in the Web page. Has the effect of

  FIGS. 9A and 9B are diagrams illustrating an example of detecting an update location in the present embodiment. 9A is the HTML source of the Web page of FIG. 4A and FIG. 9B is the Web source of FIG. 4B.

  In the comparison of update locations in this embodiment, as preprocessing, comments, labels, line feed characters, and blank characters that are not related to display are removed from the source code of two Web pages to be compared. Thereafter, matching processing is performed on the two source codes to obtain corresponding elements.

  A normal character string is matched in units of characters, but a tag is matched as one element that cannot be decomposed.

In the example of FIG. 9, it is detected by the matching process that the tag “<img src =“ new.gif ”>” has been added after the update.

  Even if a normal character is deleted after the update, it is not detected as an update location, but when a tag is added / changed / deleted, the range affected by the tag is set as the update location.

  As for the image, even if the name of the image has not been updated, if the update date of the two image files to be compared is different, the entire image is set as the update location.

  In FIG. 9, an image “top.jpg” is set before “new.gif” in the source. However, in the present invention, “new.gif”, which is an updated portion, is set from “top.jpg”. Read first and check the size information of the image.

  FIGS. 10A, 10B, and 10C are diagrams showing the transition of the display position.

  FIGS. 10A, 10B, and 10C show the display positions of the first, second, and third update locations, respectively, and are obtained automatically or after user operation after obtaining a Web page. The screen changes to the screen of 10 (a).

  In the present embodiment, it is possible to sequentially switch from the display position in FIG. 10A to the display positions in FIGS. 10B and 10C by an operation from the user, an automatic display position switching function, or the like.

  At this time, in order to notify the user of the presence of the next priority display candidate, some display is performed on the display unit. After the last update location is displayed, the display operation returns to the display location of the first update location by the switching operation.

  Further, when the user performs a confirmation operation, the highlighted display of the update location and the display notifying the presence of the next update location are erased at the current display position, and the normal Web browsing screen is restored.

  As described above, according to the present embodiment, the mobile terminal 10 is provided with the page storage unit 12 that temporarily stores the web page when browsing the web page, and when the same web page is browsed again, the control unit 17 compares the content of the page stored last time and moves the display range so that the updated part is displayed at a predetermined position in the display unit. Can be obtained.

  When browsing a Web page, even if it is an information device that has only a small display unit such as a portable terminal, a part containing information that the user wants to display preferentially is displayed quickly without performing scrolling operations. Can be displayed on the screen.
