Description

  The present invention relates to a web browser and a display device that display a web page described in a markup language document.

  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 or images. Software (computer program) that performs processing for interpreting tag information included in a document described in such a markup language and browsing the contents of the document is called a web browser.

  A web browser operates on a computer device typified by a personal computer (PC), and when browsing a web page, a URL (Uniform Resource) for specifying the web page in accordance with a communication protocol such as an http protocol via a communication network. Locator) is used to request and acquire a markup language document that constitutes a web page from the website. The web browser interprets the acquired markup language document, acquires the data if there is an image embedded in the document, and displays the data on the display device through layout and rendering processing of the display item. Display the page screen.

  Web browsers generally have one function, without having to perform complicated operations such as manually entering URLs and following links hierarchically from the upper screen when revisiting a web page once visited, In order to immediately shift to the web page, it has a bookmark (or “favorite”) function for registering the URL.

  When the target web page is designated by the bookmark designation operation by the user, the browser accesses the web site of the corresponding URL, requests the corresponding markup language document, and downloads the data. At this time, a time required for the download and a processing time for constructing the display data by interpreting the acquired markup language document are required, and the user is kept waiting. Conventionally, during such a standby time, an icon such as an hourglass has been displayed.

  By displaying such an icon, the user can recognize that the process is in progress, but it is difficult for a beginner or a person unfamiliar with the operation to understand what is currently being performed. Also, for those who are used to the operation, it is tedious to just look at the hourglass and wait until the requested web page is displayed.

  The present invention has been made in such a background, and an object of the present invention is to prepare for display of a web page when the web page that has been visited once is shifted to the web page in a web browser and a display device. It is an object of the present invention to provide a user interface that allows the user to intuitively understand the operation status during the waiting time until the image is set.

  The web browser according to the present invention stores a captured image of a web page screen obtained by displaying a markup language document corresponding to a URL registered as a bookmark, and corresponds to the bookmark when the bookmark is selected. A step of acquiring a markup language document from a URL via a communication network; a step of displaying a captured image of the web page screen before the markup language document is acquired and ready for display; and the markup language document After the preparation for the display is completed, a step of switching from the captured image of the web page screen to the display of the markup language document is provided.

  When a user designates a bookmark, until the markup language document corresponding to the bookmark is acquired and the web page is ready to be displayed, the display (preferably dynamic display) is performed using the captured image of the web page screen. )I do. As a result, the user can be informed intuitively of the situation in which the web page information is being ordered from the website via the communication network. In addition, since the display is switched from the dynamic display to the web page display of the newly acquired markup language document after the display preparation is completed, the display of the target web page is not particularly delayed by the processing of the present invention.

  The captured image is a reduced copy of the web page screen, and in the dynamic display, the captured image is gradually enlarged from a small screen size so that the captured image approaches from near to far. Also good. As a result, the user can virtually feel the situation in which the data of the markup language document approaches from a distance. Note that there may be an operation of temporarily returning to the smaller side in the process of changing from the initial minimum size to the final maximum size, and the present invention does not exclude such an operation.

  The method may further include a step of arranging the captured images as bookmarks in a two-dimensional arrangement on a screen and a step of selecting a bookmark by selecting an arbitrary bookmark by the user. As a result, the image of each web page can be visually recognized even though it is reduced, so that the contents of the bookmark can be understood more easily than the selection of the bookmark by the conventional list display.

  Another web browser according to the present invention includes a step of accumulating a browsing history of a web page, a step of storing a captured image of each viewed web page screen, and a web page having the history accumulated from a current web page. A step of acquiring a markup language document corresponding to the web page when receiving an instruction to shift to the screen, and a captured image of the web page screen before the markup language document is acquired and ready for display. And a step of switching from dynamic display of the captured image to display of the markup language document after preparation for display of the markup language document is completed. And

  Even when a markup language document is acquired based on a web page browsing history, it takes a certain amount of time to prepare for display. In the present invention, the time is used to perform dynamic display using the captured image of the web page screen, and then the display is switched to the display of the markup language document. For example, in the step of performing the dynamic display, the current web page is gradually switched to the captured image of the web page screen for display. More specifically, the screen after switching is slid into the display screen, driven in, dropped in, or faded in. At the same time, the screen before switching is slid out from the display screen or faded out. By adopting such a display form, the operation status of the return operation and the advance operation based on the history can be easily understood by the user.

  According to another aspect, the web browser according to the present invention stores a captured image of the display screen for each URL of each browsed web page, detects that a URL is designated by the user, The step of reading the captured image corresponding to the designated URL and the step of dynamically displaying the captured image until the display preparation process of the web page is completed are provided. The designation of the URL by the user is optional, such as manual input, bookmark selection, and selection based on history. If there is no captured image corresponding to the designated URL, a default image prepared in advance can be used.

  A display device for displaying a web page according to the present invention includes a storage means for storing a captured image of a web page screen obtained by displaying a markup language document corresponding to a URL registered as a bookmark, and an operation for accepting a user operation. When a bookmark is selected by the user's operation with the accepting means, the means for acquiring the markup language document from the URL corresponding to the bookmark via the communication network, and the markup language document is acquired and ready for display. Display means for displaying the captured image of the web page screen before, and control means for switching from the captured image of the web page screen to the display of the markup language document after the markup language document is ready for display; It is provided with.

  Another display device for displaying a web page according to the present invention is a display device for displaying a web page, including a history storage means for storing a browsing history of a web page, and a markup language document for each browsed web page. Cache storage means for temporarily storing in the cache storage area, screen storage means for storing captured images of the browsed web page screens, operation accepting means for accepting user operations, and current web Upon receiving an instruction to shift from the page to the web page in which the history is accumulated, a means for acquiring a markup language document corresponding to the web page from the cache storage area, and the markup language document is acquired and Before the display is ready, the dynamic display using the captured image of the web page screen A Cormorant display means, after preparing the display of the markup language document is in place, characterized in that a control means for switching from said web page screen capture image on the display of the markup language document.

  There may be further provided bookmark means for arranging captured images, which are reduced copies of the web page screen, two-dimensionally arranged as bookmarks on the screen and selecting a bookmark by the user selecting an arbitrary bookmark. Further, when a bookmark is selected, the title and / or URL of the capture image may be displayed in the vicinity thereof.

  The operation accepting unit preferably includes a touch panel having an input area overlapping the display screen of the display unit.

  According to the present invention, during a waiting time until a web page is displayed according to a user operation, a captured image of the screen of the web page acquired in the past is displayed, and a markup language document is displayed. After the preparation is completed, the display is switched from the captured image on the web page screen to the display of the markup language document. In other words, when a web page that has been visited has been visited, the web page that has been viewed before is displayed during the waiting time until the web page is ready for display. Provides an interface that does not make time conscious.

  During the waiting time, dynamic display based on the captured image of the screen of the web page, for example, by gradually expanding the captured image from a small screen size so that the captured image approaches from near to far, The current operation status according to the user operation is intuitively understood.

  According to another invention, when an instruction to move from a current web page to a web page with accumulated history is received, before the markup language document is acquired and ready for display, By dynamically displaying the captured image, it is possible to provide an interface that does not make the user aware of the waiting time. For example, in the dynamic display according to the “return” operation or the “advance” operation, the current operation state according to the user operation can be intuitively understood by sliding the captured image screen into the display screen. Is done.

  Further, according to another aspect, the web browser according to the present invention stores a captured image of the display screen for each URL of each browsed web page, detects a designation by a user, The step of reading the captured image corresponding to the designated URL and the step of dynamically displaying the captured image until the display preparation process of the web page is completed are provided. According to the present invention, when the user browses the web page before, the display screen displayed after the display preparation process is completed is stored as a captured image. The captured image corresponding to the URL is read out and dynamically displayed while the display preparation process for the web page is completed, so that the user can recognize the web page to be displayed from now on, and part of the content is displayed. It is possible to realize an animation expression as a very excellent user interface that can be communicated and is interesting, without waiting for a display preparation process by a browser. In particular, since rendering processing is always required to display a web page by a browser, it is beneficial to store a captured image that has been rendered in advance as described above.

  Therefore, according to the present invention, a user interface that is easy to use for elderly people and children can be obtained.

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

  FIG. 1 is a block diagram showing a schematic configuration of a markup language document processing apparatus 100 equipped with a browser that implements the markup language document display method of the present invention. The markup language document processing apparatus 100 is typically a PC, but is not limited thereto, and may include any apparatus that performs data processing for displaying a markup language document. For example, it may be a PDA (Personal Digital Assistant), a car navigation device, a mobile phone, a mobile display terminal, or the like.

  In FIG. 1, a control unit 101 includes a CPU and controls the entire apparatus by program control. Storage unit 120 in the present embodiment includes ROM 121 and RAM 123. In addition, other storage devices such as a hard disk device may be included. The ROM 121 is a nonvolatile memory that stores various programs executed by the CPU of the control unit 101 and necessary data, and includes at least a rewritable area. The RAM 123 is a memory that provides a work area for the CPU and a temporary data storage area. The storage unit 120 also provides a cache storage area in the present embodiment. The IrDA 111 is an infrared interface unit, and has a function of receiving an operation instruction from a user from an external remote controller, a mobile phone or the like (not shown) and inputting it to the control unit 101. The input unit 113 includes a keyboard, a mouse, a touch panel, and the like, and has a function of receiving an instruction and data input from a user and transferring the data to the control unit 101. A network interface (I / F) 115 is connected to a communication network wirelessly or by wire, and provides a communication function of accessing a website on the Internet and sending and receiving e-mails.

  The signal processing unit 102, under the control of the control unit 101, digitizes the voice input from the microphone 107 and delivers it to the control unit 101, converts the voice output data from the control unit 101 to analog and outputs it to the speaker 108, This is a part that performs various types of signal processing to exchange signals with an image processing unit 103, which will be described later, and can be configured by an LSI called FPGA (Field Programmable Gate Array) as an example.

  The image processing unit 103 has a function of receiving display data from the signal processing unit 102 and displaying the display data on a display unit 105 such as a liquid crystal display (LCD). The image processing unit 103 can be configured by a display LSI that supports graphic processing.

  FIG. 2 is a block diagram showing functions of the browser in the present embodiment. The browser (web browser) 200 is realized by software (computer program) executed by the control unit 101 in FIG.

  The ML document acquisition unit 211 acquires the ML document data 201 to be displayed and passes it to the browser engine 213. The ML document data 201 can be acquired via a communication network or acquired from the cache recording area 240.

  The browser engine 213 converts the ML document data into display data and outputs it to the display unit 105. The function of the browser engine 213 will be described later.

  The URL search unit 215 confirms the URL of the ML document from the ML document acquisition unit 211, checks whether the web page of the URL has been stored in the capture image database (DB) 120, and for an ML document that has not been stored. Then, the capture image creation unit 219 is activated to create a capture image based on the display data of the ML document from the output of the browser engine 213.

  The captured image is stored in a captured image database (DB) 250 in the storage unit 120. The captured image database 250 stores a captured image of a web page to be browsed and its URL in association with each other. In the present embodiment, the captured image has been subjected to size reduction processing so as to be smaller than the original screen size. Thereby, the data amount of the captured image is reduced, and the storage capacity necessary for the captured image can be reduced. Also, the processing load for displaying the captured image is reduced.

  The captured image DB 250 may also store a default image used in place of the captured image. When the captured image is not displayed when the captured image is displayed, the default image acquisition unit 218 acquires the default image and provides this instead of the captured image. The default image is arbitrary image data prepared in advance having the same size as the captured image.

  A cache storage area 240 is also provided in the storage unit 120. The cache storage area 240 is an area for temporarily storing the URL and ML document data of the web page once browsed, and the cache operation is controlled by the cache control unit 241. For example, when browsing a plurality of sequentially viewed web page screens, the ML document data stored in the cache storage area 240 is read and used without downloading the ML document data again from the website again. can do.

  In the storage unit 120, a bookmark storage area 220 controlled by the bookmark control unit 221 and a history storage area 230 controlled by the history control unit 231 are also provided.

  The bookmark control unit 221 and the history control unit 231 operate according to the instruction content from the user operation reception unit 260 that receives a user operation. For example, the bookmark control unit 221 executes the operation in response to an instruction operation such as new registration of a bookmark, selection of a registered bookmark, and deletion / organization of a registered bookmark by the user. The history control unit 231 stores / updates history information according to various operations such as designation of a new URL, designation of a bookmark, forward operation, and backward operation by the user.

  When the ML document data is acquired along with the movement of the web page based on the history or when the bookmark is selected, the capture image acquisition unit 216 captures the corresponding ML document from the history storage area 230 and the bookmark storage area 220, respectively. The image is retrieved and read out and sent to the animation realization unit 217. The animation realizing unit 217 processes the acquired captured image and outputs a moving image for dynamic display based on the captured image to the display unit 105 during a period until display data is output from the browser engine 213. That is, the animation realization unit 217 can execute processing in parallel with the browser engine 213. In the present embodiment, as will be described later, the mode of dynamic display is changed between selection of a bookmark and movement of a web page based on a history. The selection of the bookmark and the movement of the web page based on the history can be distinguished based on the user's operation content.

  FIG. 3 shows an internal configuration of the browser engine 213 as a main functional unit in the browser 200 shown in FIG. The browser engine 213 has functions of the parser 21, the page maker 23, and the formatter 25. The parser 21 interprets the logical structure of the markup language (ML) document 201 to be displayed obtained from the ML document acquisition unit 211, 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 213, the content of the markup language (ML) document 201 is displayed on the display screen of the display unit 105.

  FIG. 4 shows information stored in the storage unit 120 in the present embodiment. The storage unit 120 stores a menu operation program 301, a software keyboard operation program 302 (when a hardware keyboard is not provided), various programs such as the browser 200, a bookmark storage area 220, a history storage area 230, Various data storage areas such as a cache storage area 240 and a captured image DB 250 are provided.

  Hereinafter, the operation of the browser in the present embodiment will be described.

  FIG. 5 shows a transition example of the display screen by the browser when the bookmark is selected. Bookmarks are usually selected by selecting a menu item from the “Bookmarks” menu prepared in the menu bar of the browser screen or by displaying a bookmark list (a list of web page titles) by specifying a bookmark icon. By selecting a desired bookmark from among them, a target URL is specified. Based on this, the browser outputs an ML document acquisition request of the URL to the website via the communication network. It takes some time until the data of the ML document (including necessary image data embedded in the document) is acquired via the communication network. Furthermore, even after all necessary data has been acquired, it takes a considerable amount of time for processing (herein referred to as rendering) to convert it into display data. Conventionally, as described above, only an hourglass or the like is displayed during the time (standby time) from the designation of a bookmark until the web page is actually displayed. On the other hand, in the present invention, before the ML document is acquired and ready for display, the captured image of the web page screen acquired in the past is displayed. In this example, the captured image of the web page screen is dynamically displayed. However, if there is no captured image for the URL, the default image is used. After the preparation for displaying the ML document is completed, the screen is switched from the captured image on the web page screen to the ML document display screen 405 (FIG. 5E).

  In this embodiment, the captured image is a copy of the web page screen with a reduced size. In the example of FIG. 5, the captured image approaches from near to far as shown in FIGS. 5 (a) to 5 (d). As it comes, it gradually expands from a small web page screen size. By such an operation, it is possible to virtually feel that the data to be browsed is acquired from a distance via the communication network. In addition, although the contents of the screen are past data, it is intuitively understood that the target information is being obtained because it is the screen of the web page specified by the user. 5A to 5D, the dynamic display is represented by the four transition screens 401 to 404. However, the screen is actually shaken or swiveled using more transition screens. It is also possible to introduce an action. In the example of the figure, the screens 401 to 404 are shown in an inclined form in order to give a sense of perspective, but the inclination is not an essential condition. In addition, the screen size starts from the size of the captured image (minimum size), and the process of enlarging the size stepwise is performed. However, if the number of steps is large, reduction operations may be temporarily mixed in the middle. . Further, the number of stages of dynamic display need not be fixed. Since the actual standby time may vary depending on the web page or various factors such as the communication environment and the performance of the browser display device, the number of stages of dynamic display is preferably variable according to the standby time. For example, the first stage in which the captured image of the detailed view advances from the upper center of the display screen to the center, the second stage in which the captured image fluctuates in the shape of, for example, eight, and the size of the captured image occupies the entire display screen Consider a display mode that prepares a third-stage video that grows to a certain extent, repeats the second stage when the standby time is prolonged, and moves to the third stage when display preparation is complete. It is done.

  FIG. 6 shows a transition example of the display screen by the browser during the “return” operation based on the history data. The “return” operation is generally instructed by the user instructing a predetermined mark icon prepared on the menu bar of the browser screen. Based on this, the browser acquires the ML document of the URL from the cache storage area 240, and proceeds to display processing. If the ML document of the URL is not in the cache storage area 240, an acquisition request for the ML document of the URL is output to the website via the communication network. When an ML document is acquired from the cache storage area 240, the waiting time until display is shorter than when accessing a website, but still requires a corresponding display processing time. Therefore, in the present invention, before the ML document is acquired and ready for display, the current web page is displayed in a step-by-step manner by switching to a captured image of the web page screen acquired in the past. Next, after the preparation for displaying the ML document is completed, the captured image on the web page screen is switched to the display of the ML document.

  In the switching display of the present embodiment, as shown in FIGS. 6A to 6D, the screen 511 after switching is slid into the display screen, and the screen before switching is slid out from the display screen. In this example, during the “return” operation, the screen is displayed so that the previous screen slides from the left side toward the screen and moves to the front. The screen before switching may be slid in while the screen before switching remains stationary without sliding out. As described above, the captured image of the web page screen is a reduced copy of the web page screen. In the switching display, the reduced copy is enlarged to the original size and used. After FIG. 6D, the ML document screen is displayed as shown in FIG. 6 (d) and FIG. 6 (e) are the same in the drawing, but FIG. 6 (d) is an enlarged view of a reduced capture screen of the web page in the past, whereas FIG. 6 (e). Is a rendering of the ML document of the URL. Therefore, the image quality (resolution) of both screens is different.

  The number of transition screen stages is not limited to the illustrated example. If the waiting time is short and the ML document is rendered in time, the rendered result of FIG. 6E is displayed without displaying the screen after the switching (capture screen) as shown in FIG. 6D at the end of the screen transition. A screen may be displayed.

  Although not shown, the screen transition in the case of the advance operation slides in from the opposite side (right side) to the example shown in FIG. In this embodiment, in order to unify the operations, the slide-in operation is performed even when data is acquired from the website instead of the cache storage area 240 in the return operation and the advance operation.

  Hereinafter, various operations of the web browser in the present embodiment will be described with reference to flowcharts.

  FIG. 7 shows a processing flow for acquiring a captured image. In this example, the capture image is configured to be performed every time an ML document based on a URL is acquired. An ML document is acquired when a bookmark is specified, when a new URL is specified, or when a history is specified (return and advance operation). If the specified URL is not valid in any case (S11, No), this process is terminated. If it is valid (S11, Yes), the acquisition of the ML document is started (S12). As described above, in the case of history designation, the cache storage area 240 is preferentially obtained, but in the case of bookmark designation and new designation, it is obtained from the website. Web page display is performed based on the acquired ML document (S13). Next, a captured image of this web page screen is acquired (S14). In the present embodiment, the captured image is reduced to a predetermined size. If a captured image corresponding to the same URL does not exist in the captured image DB (S15, No), the captured image is newly stored together with the URL (S16). If it already exists, the captured image is overwritten and saved along with the URL (S17).

  By such processing, it is possible to save the screen of the web page that has been browsed as a captured image. In the example of FIG. 7, the presence / absence of an image corresponding to the same URL is checked after acquisition of the capture image. However, the image corresponding to the same URL already exists in the capture image DB by checking before acquisition of the capture image. For example, the capture image may not be acquired and updated.

  According to the configuration in which the captured image corresponding to the same URL is overwritten, when the web page is updated, the captured image can be updated accordingly. In the configuration in which capture image acquisition and update are not performed, the update of the web page cannot be reflected in the capture image, but the processing load for acquiring and updating the capture image each time the ML document is acquired can be reduced.

  FIG. 8 shows a dynamic display flow (1) that operates when a bookmark is specified or a new URL is specified.

  First, the validity of the URL is checked (S21). If it is not valid, this process is terminated. If it is valid, acquisition, interpretation and rendering of the designated ML document is started (S22). If the captured image of the web page of the URL exists by searching the captured image DB (S23, Yes), it is acquired (S25). If there is no captured image, a default image is acquired (S24). Based on the captured image (or default image), the animation realizing unit 217 performs animation display as shown in FIG. 5 (S26). When rendering of the ML document is completed (S27, Yes), a web page is displayed (S28).

  FIG. 9 shows a dynamic display flow (2) that operates when a history is designated.

  First, the validity of the URL is checked (S31). If it is not valid, this process is terminated. If it is valid, acquisition, interpretation and rendering of the designated ML document is started (S32). If the captured image of the web page of the URL exists by searching the captured image DB (S33, Yes), it is acquired (S35). If there is no captured image, a default image is acquired (S34). Based on the captured image (or default image), the animation realizing unit 217 performs animation display as shown in FIG. 6 (S36). When rendering of the ML document is completed (S37, Yes), a web page is displayed (S38).

  FIG. 10 shows another display example of the bookmark as a modification of the present embodiment. As described above, the conventional bookmark designation is selected from the bookmark list. In that case, it was often a bookmark registered by itself only from the character string in the list, but it could not recognize which site the web page was. In this modification, a bookmark is presented to the user using the captured image (reduced) registered in the captured image DB so that the web page contents can be visually recognized as an image. It is. In the configuration of FIG. 2, the captured image DB 250 stores not only the URL registered in the bookmark storage area 220 but also the captured image of the URL stored in the history storage area 230. For displaying the bookmark in this modification, a captured image corresponding to the URL registered in the bookmark storage area 220 is selected and used.

  FIG. 10A shows an example of a bookmark screen in this modification. In this example, a plurality of capture screens corresponding to a plurality of URLs registered in the bookmark storage area 220 are displayed as perspective images with perspective as if the cards or karuta were viewed on the table diagonally from above. ing. That is, many captured images are displayed in a small size, and the captured image is displayed in a larger size as it gets closer. (The captured image is shown in white in FIG. 10 for the sake of convenience, but is actually an image obtained by reducing the web page.) Although the arrangement position of the captured image is arbitrary, for example, a frequently viewed URL or recently A captured image of a URL that meets a predetermined condition such as a browsed URL may be positioned in front. Although such a bookmark screen is not particularly limited, it is preferable to use a touch panel with an input area overlapping the display screen as one of the operation units. In an apparatus using a display device with a display size of a certain size or larger, even the smallest captured image can be displayed larger than the size of a human fingertip, and if the target bookmark can be indicated by the captured image, the operation is intuitively understood. This is because bookmarks can be easily and quickly instructed.

  In the bookmark screen of FIG. 10A, for example, when the user designates a capture image 604, the captured image displayed as a perspective image until now is displayed in an upright state as shown in FIG. 10B. Let When the captured image is erected, the outline shape of the selected captured image changes from the original square shape to a rectangular shape, and can be clearly distinguished from other captured images. Along with the erecting of the captured image, highlighting of the captured image and / or darkening (reducing the brightness) of the display area other than the captured image may be performed.

  When the captured image is selected (upright), the title and URL of the captured image 604a are also displayed in the vicinity thereof. Displaying the title and URL is useful for recognizing the web page when it is difficult to understand the content of the web page only by the captured image. By displaying the title and URL for the first time when the captured image is selected on the bookmark display screen, the display of the title and the like is more effective in recognizing each captured image than when the title and URL of each captured image are always displayed when the bookmark is displayed. There is no need to get in the way or to further reduce the image. Although the display position of the title and URL is not particularly limited, as a preferable example, if there is an empty area (an area where no other captured image exists) around the upright capture image 604a, the display position is displayed there. . If there is no empty area, it is displayed in the surrounding displayable area.

  In the state of FIG. 10B, when the user further instructs an upright captured image 604a, a dynamic display is performed as if the captured image is blown up in the wind as shown in FIG. The display shifts to the dynamic display described in FIG. The dynamic display of FIG. 10C is not essential, but a smooth transition of the dynamic display is performed as a “connection” at the time of transition from the bookmark screen of FIG. 10B to the dynamic display of FIG.

  According to the above embodiment, after the user instructs display of the ML document, during the standby time until the web page is displayed, the past captured image of the web page is used to respond to the user operation. By performing the target display, it is possible to provide a user interface in which the content of the operation is intuitively easy to understand and does not make the standby time feel long.
