  An example of a display screen is shown in FIGS. FIG. 1A shows an HTML document display screen. As shown in FIG. 1A, a number is displayed adjacent to each text. When the number “8” is input, the text corresponding to “8” is enlarged and displayed. As described above, when the technique of the present embodiment is used, it is possible to enlarge a desired text only by pressing a number once. Hereinafter, embodiments of the present invention will be described in more detail.

(Details)
FIG. 2 shows a functional block diagram of portable terminal 10 in the present embodiment. As illustrated in FIG. 2, the mobile terminal 10 according to the present embodiment includes a content acquisition unit 11, a content analysis / superimposed image creation unit 12, an output control unit 13, an image output unit 14, an operation input unit 15, and a speech synthesis output unit. 16, a storage device 17, a display device 18, an input device 19, and an audio output device 20.

  The content acquisition unit 11 has a function of acquiring an HTML document designated by the user from a Web server on the network. The content analysis / superimposed image creation unit 12 has a function of analyzing the acquired HTML document and creating an image of a number and text to be displayed superimposed on a normal HTML document image.

  The output control unit 13 has a function of performing control and the like for enlarging and displaying a predetermined text according to the operation content from the user.

  The image output unit 14 has a function of sending the image data received from the output control unit 13 to the display device 18 and causing the display device 18 to display an image. The operation input unit 15 has a function of transmitting the operation content received from the input device 19 to each function unit. The speech synthesis output unit 16 has a function of converting text data received from the output control unit 13 into speech data and outputting the speech data to the speech output device 20. The storage device 17 is, for example, a RAM (random-access memory).

  The display device 18 is a small-sized display device that is mounted on a mobile phone, for example. The input device 19 has a number key, a scroll key, a determination key, and the like, and has a function of sending a signal corresponding to the key to the operation input unit 15 when the user presses the key. The voice output device 20 has a function of outputting voice data received from the voice synthesis output unit 16 as voice.

  Note that the mobile terminal 10 is a mobile phone, a PDA, or the like having a computer configuration with a CPU or the like, and each functional unit in the present embodiment is realized by executing a program on the mobile terminal 10. Is. For example, the program may be acquired from a website as an application of a mobile phone as the mobile terminal 10.

  Next, the operation of the mobile terminal 10 will be described in detail with reference to the flowchart of FIG.

  First, the mobile terminal 10 acquires an HTML document from a web server on the network based on an operation from the user (step 11). The acquired HTML document is stored in the storage device 17 of the mobile terminal 10.

  Subsequently, the content analysis / superimposed image creation unit 12 acquires elements within a range that can be displayed on one screen of the display device 18 of the mobile terminal 10 from the head of the HTML document accumulated in the storage device 17 (step 12). . Note that it is possible to grasp which range in the HTML document can be displayed in one screen by analyzing the HTML document.

  FIG. 4A shows the structure of a general HTML document. In the example of FIG. 4A, since the range shown in A is displayed on one screen as shown in FIG. 4B, the content analysis / superimposed image creation unit 12 acquires elements in the range of A. Note that common tag parts such as <HTML> and <body> are excluded from the scope of acquisition.

  Next, the content analysis / superimposed image creation unit 12 creates a correspondence table for associating numbers displayed adjacent to each text of the document displayed on the display device 18 with each element of the HTML document. The created correspondence table is stored in the storage device 17 (step 13).

  Here, first, the contents of the elements acquired in step 12 are assigned numbers in order from the upper layer according to the hierarchical relationship of the tags for setting headings. Furthermore, the number which shows the order which the said tag appears in the said range is provided, and these are matched and stored.

  In other words, as shown in the example in FIG. 4A, when the hierarchy is <H1>, <H2>, ... <Hn>, <p>, ... First, (a) a serial number from 0 to k (the number of tag elements minus 1) and a tag appearance number are assigned to the contents of the element of the tag <H1>. (B) A serial number from k + 1 to m and a tag appearance number are assigned to the contents of the element of the tag <H2>. (C) A serial number from m + 1 to p and a tag appearance number are assigned to the contents of the element of the tag <H3>. (D) Similarly, the serial number and tag appearance number following (c) are assigned to the contents of the <Hn> tag elements below <H4>. Furthermore, the serial number and the tag appearance number following (d) are assigned to the contents below <p>. Of course, this process is terminated when there are no more elements to be numbered in the middle.

  As a result of such processing, in the case of the HTML document in the range shown in A of FIG. 4A, the correspondence table shown in FIG. 5 is created. In this correspondence table, for example, “Title 2” is the content of the second element of the <H1> tag, and the tag appearance order is 7th in the entire acquired range. And 7 is assigned as the tag appearance number. The element in the acquired HTML document in the acquired range can be specified by the tag appearance number.

  In the present embodiment, the serial number values used for text selection are set to 0 to 9 so that the text to be enlarged can be selected easily (by one push). Therefore, even when ten or more tags are included in one screen, the assignment of the serial number is stopped when the serial number value exceeds 9, and the process proceeds to the next process. Therefore, in the example of FIG. 4A, the serial number value is not given to the content e as shown in FIG. Of course, although it is not one push, a serial number value greater than 9 may be given, or a serial number value greater than 9 may be given by characters such as a, b, c, d.

Further, in the present embodiment, numbers are sequentially assigned from the higher layers according to the hierarchical relationship of tags as serial number values. As a result, even when the serial number value is limited from 0 to 9, it is possible to reliably assign the serial number value to an important text such as a title. In addition, it is good also as analyzing a HTML document and giving a serial number value in an order from the text with a small character size. This makes it possible to reliably enlarge and display a small text. Moreover, it is good also as giving a serial number value only to a specific tag (for example, <p>), and there is no restriction | limiting in particular in the method of giving a serial number value.
Also, the tag appearance order may be any information as long as it can specify the elements in the HTML document in the acquired range. For example, the appearance order may be given for each tag type (<H1>, etc.). Thereby, for example, if “second element of <H1>” is specified, the element can be uniquely specified in the HTML document in the acquired range.

  Subsequent to step 13 in FIG. 3, when the content analysis / superimposed image creation unit 12 displays the HTML document in the range acquired in step 12 on the display device 18, the content analysis / superimposed image creation unit 12 is adjacent to each text in the document and connected. In order to display the number value superimposed on the document, a drawing image for each sequential number value and its display position are generated (step 14). Further, a drawing image of each text and its display position for generating a text corresponding to the serial number value to be enlarged and superimposed on the document are generated for each serial number value (step 15).

  That is, when the HTML document in the range acquired in step 12 is displayed on the display device 18 as shown in FIG. 4B, each serial number displayed at each position shown in FIG. And a drawing image (text drawing image) of each text displayed at each position shown in FIG. 6B.

  As shown in FIG. 5, since the serial number is associated with the tag appearance number, the display position of a serial number corresponds to the tag appearance number corresponding to the serial number by referring to the correspondence table. It can be calculated as the position where the content of the element is displayed. This position can be calculated by performing HTML analysis in the same manner as when displaying an HTML document.

  Also, the display position and display size of the text may be the position and size at which the content of the element corresponding to the tag appearance number corresponding to the text is displayed. This can also be calculated by referring to the correspondence table and performing HTML analysis in the same manner as when displaying an HTML document.

  The generated text drawing image and display position are stored in the storage device 17 in association with the sequential number values in the correspondence table.

  Next, the content analysis / image creation unit 12 analyzes the HTML document for one screen acquired in step 12 in the same manner as in the normal case, and creates a document image to be displayed on the display device 18. Then, the document image, each sequential drawing image and their display position are passed to the output control unit 13, and the output control unit 13 sends them to the image output unit 14. The image output unit 14 displays the document image on the display device 18 and displays each sequential drawing image superimposed on the document image at each display position (step 16). An example of the display screen at this time is as shown in FIG. At this time, the text drawing image corresponding to the serial number value of 0 may be enlarged at a predetermined magnification and superimposed on the display position of the text drawing image. An example of the display screen in this case is shown in FIG.

  Thereafter, the output control unit 13 of the portable terminal 10 monitors whether there is an input from the up / down key (referred to as a scroll key) from the operation input unit 15 and whether there is an input from the number key (step). 17).

  Now, for example, when the user who sees the display screen of FIG. 7 or 8 wants to enlarge the character c of the content c, he / she presses the “8” button of the input device 19. Then, “8” is sent from the operation input unit 15 to the output control unit 13, and the output control unit 13 from the text drawing image / display position group stored in the storage device 17 in association with the serial number value, A text drawing image corresponding to “8” and its display position are acquired. Then, the text drawing image corresponding to “8” is enlarged at a predetermined magnification (step 18), and the enlarged text drawing image and the corresponding display position are sent to the image output unit 14. As a result, the image shown in FIG. 9 is displayed on the display device 18 (step 19). As shown in FIG. 8, when there is already enlarged text, the text drawing image corresponding to “8” is displayed after erasing the text image.

  When the scroll key is input, the output control unit 13 sends the received scroll key input information to the content analysis / superimposed image creation unit 12, and the content analysis / superimposed image creation unit 12 corresponds to the scroll key input information. The process from step 12 is performed again by acquiring the elements of the HTML document for one screen after scrolling by the amount.

  FIG. 10B shows a screen display example when “Title 2” is scrolled to the uppermost stage of the screen from the state of FIG. 8 (FIG. 10A).

  When a number is input in step 17, the text drawing image may be enlarged and displayed, and the text may be output as a voice. In this case, the output control unit 13 receiving the input of the number acquires the text corresponding to the number from the correspondence table, and sends this text to the speech synthesis output unit 16. The speech synthesis output unit 16 converts the text into speech data and sends the speech data to the speech output device 20 so that the speech output device 20 outputs speech corresponding to the text.

  In the above embodiment, from the viewpoint of simplicity of operation, the text to be enlarged is selected using a one-digit number. However, the text can be selected without using the number. It is. In this case, in the correspondence table, instead of the serial number, the contents and position information for each tag appearance number are stored. Further, the text drawing image and the display position are stored in association with the tag appearance number. And when displaying an HTML document image, it displays without superimposing anything.

  On the other hand, a cursor that moves up and down is displayed on the screen on which the document image is displayed. When the user moves the cursor with a predetermined key and presses the Enter key, the mobile terminal extracts the text drawing image and display position corresponding to the cursor position at that time using the tag appearance number of the correspondence table And zoom in on it. However, since this method is not a one-push operation, it takes more time to operate than a method using numbers.

  The present invention is not limited to the above-described embodiments, and various modifications and applications are possible within the scope of the claims.
