Next, a specific example of the present invention will be described with reference to the flowcharts of FIGS. 3, 4, 7, and 8. FIG.
Note that these flowcharts show that the CPU 23 has the ROM
25 shows a state in which the program stored in the storage unit 25 is executed.

(Embodiment 1) FIG. 3 is a flowchart showing a flow of processing of the control unit 10 in the Web browsing apparatus of this embodiment. First, the control unit 10 receives a request from the operator via the user interface unit 8 (step S1), checks whether the request is a termination request (step S2), and terminates the processing if the request is a termination request. . If it is not an end request, it is checked whether or not the operator's request is an access request to the Internet (step S3).
If it is not an access request, the process moves to step S8.

In step S 4, the URL (the address of the home page on the Internet) specified by the operator is passed to the page data acquisition unit 2. The page data acquisition unit 2 connects to the Internet via the Internet connection unit 1. Further, in step S5, the page data acquisition unit 2 acquires, via the Internet connection unit 1, the data of the home page indicated by the URL passed from the control unit 10, and stores the data in the storage unit 11.

Next, in step S6, the control unit 10
The page data acquired by the page data acquisition unit 2 is passed to the page data analysis unit 5. The page data analysis unit 5 shapes the page data according to the screen size of the display device 22, outputs the display data, and uses the link destination URL extraction unit 3 and the shortcut key assignment unit 4 to output the display data.
Among the anchor tags in the page data, the one specifying the link destination is registered in the anchor table and assigned with a shortcut key. The processing flow of the page data analysis unit 5 will be described based on the flowchart of FIG.

First, in step T1, the page data acquisition section 2 analyzes the acquired HTML data to acquire analysis data for one tag. In step T2, H
Check whether all the analysis of TML data is completed,
If not, the process proceeds to step T3. If completed, the process is terminated and the process returns to step S7. In step T3, layout setting for displaying on the display device 22 is performed based on the acquired tag data. For example, if the tag data to be input is a description such as <A HREF="src1.html"> to source 1 </A>, tag type: anchor tag Tag attribute: HREF = "src1.html" Target: The character string "to source 1" is displayed. In the layout setting, the display target "source 1"
The coordinates for displaying "to" and the display size are obtained. In step T4, it is checked whether the tag data is an anchor tag specifying a link destination. If so, the process proceeds to step T5; otherwise, the process proceeds to step T8.

In step T5, the link destination URL extraction unit 3 acquires the attribute value of the HREF attribute (the URL of the link destination; here, "src1.html") from the tag data. In step T6, the shortcut / key assignment unit 4 assigns all the anchors (link destinations) in the page data.
, A shortcut key is assigned so as to be unique. Here, a serial number starting from 1 is assigned. Next, in step T7, the link destination UR
The URL extracted by the L extracting unit 3, the shortcut key assigned by the shortcut key assigning unit 4, and the coordinates and size obtained by the layout setting are registered in the anchor table. In step T8, data to be displayed on the display device 22 is generated based on the layout settings. At this time, in the case of an anchor tag to which a shortcut key is assigned in steps T5 to T7, data for displaying an anchor together with the shortcut key is generated.

In step S7, the page data analysis unit 5
Is output to the display device 2 via the display unit 6.
2 and returns to step S1.

Next, in step S8, it is checked whether or not the operator's request is a request for inputting a shortcut key. If so, the flow shifts to step S9; otherwise, the flow returns to step S1. Here, it is assumed that the shortcut key is input by pressing the shortcut number following the # button. Therefore, when the operator presses the # button, it is determined in step S8 that the input is for a shortcut key.

In step S9, the number (shortcut key) pressed following the # button is obtained, and the variable ke
Set to y.

In step S10, the anchor table is searched using the variable key as a search key, and the corresponding URL is searched.
, And the process proceeds to step S4 to acquire page data.

FIG. 5 shows the input page data, the anchor table after analysis, and the display result in this embodiment.

(Embodiment 2) FIG. 7 is a flowchart showing the flow of processing of the control unit 42 in the Web browsing apparatus of this embodiment. The differences from the flowchart of FIG. 3 in the first embodiment are the page data analysis in step W6 and the scroll processing in steps W11 to W14. Here, only the difference will be described.

In step W6, the control section 42 passes the page data acquired by the page data acquisition section 32 to the page data analysis section 35. The page data analysis unit 35 shapes the page data according to the screen size of the display device 22, outputs the display data, and uses the link destination URL extraction unit 33 and the shortcut key assignment unit 34 to output the page data. Of the anchor tags inside, the one specifying the link destination is registered in the anchor table and assigned with a shortcut key. Page data analysis unit 35
Will be described with reference to the flowchart of FIG.

First, in step X1, the screen size is obtained, and the width is set to a variable w and the height is set to a variable h. Next, in step X2, the HTML data acquired by the page data acquisition unit 32 is analyzed, and analysis data for one tag is acquired. In step X3, it is checked whether or not all the analysis of the HTML data has been completed. If the analysis has not been completed, the process proceeds to step X4. If completed, the process ends, and the process returns to step W7.

In step X4, layout setting for displaying on the display device 22 is performed based on the acquired tag data. For example, if the tag data to be input is a description such as <A HREF="src1.html"> to source 1 </A>, tag type: anchor tag Tag attribute: HREF = "src1.html" Target: The character string "to source 1" is displayed. In the layout setting, the display target "source 1"
The coordinates for displaying "to" and the display size are obtained.

At step X5, it is checked whether or not the tag data is an anchor tag specifying a link destination. If so, the process proceeds to step X6, and if not, the process proceeds to step X10. In step X6, the link destination URL extraction unit 3
In step 3, the attribute value of the HREF attribute (URL of the link destination; here, "src1.html") is acquired from the tag data.

In step X7, based on the display coordinates obtained in the layout setting (step X4) and the screen size (variable w and variable h) obtained in step X1, whether the display position of this anchor tag is within the screen. It is checked whether it is within the screen, and if it is within the screen, a shortcut key is assigned by the shortcut key assigning unit 34 so as to be unique (step X8). If it is outside the screen, the process proceeds to step X9 (shortcut key) Not assigned). The shortcut keys assigned here are serial numbers starting from 1.

In step X9, the URL extracted by the link destination URL extraction unit 33 and the shortcut / key assignment unit 3
The shortcut key assigned by 4, and the coordinates and size obtained by the layout setting are registered in the anchor table. Since the display position is outside the screen, in the case of an anchor tag to which no shortcut key is assigned, the value of the shortcut key is registered as -1.

In step X10, data to be displayed on the display device 22 is generated based on the layout settings. At this time, in the case of an anchor tag to which a shortcut key is assigned in steps X6 to X9, data for displaying an anchor together with the shortcut key is generated.

FIG. 9 shows input page data, an anchor table after analysis, and a display result in this embodiment. In this figure, the anchor "To FFFFF"
Is outside the display screen, so no shortcut key is assigned. In the anchor table, the values of the link destination URL, the coordinates, and the size are registered, but the shortcut key column is -1 (the shaded portion in the figure).

Next, the processing after step W11 in FIG. 7 will be described. Step W11 to step W14
Is a shortcut key reassignment process associated with scrolling.

First, in step W11, it is checked whether or not the operator's request is a screen scroll request. If so, the flow shifts to step W12; otherwise, the flow returns to step W1.

In step W12, the scroll amount designated by the operator is obtained. In step W13, the screen scrolling unit 38 calculates the scroll amount by the calculated scroll amount.
Generate display data with the display position moved. Here, when the configuration of the anchor on the display screen is changed due to the movement of the display position, the shortcut key updating unit 39 reassigns the shortcut key.

For example, when the screen is scrolled from the display state of FIG. 9 to the position where the anchor "to label 1" is displayed, the type of the anchor on the display screen is changed as shown in FIG. "AAAAA" and anchor "BBBBB" protrude from the display screen and anchor "FFFFF
Is included in the display screen). Therefore, the shortcut key updating unit 39 assigns shortcut keys to the five anchors from the anchor “to CCCCC” to the anchor “to FFFFF”, and assigns the shortcut keys to the anchor “to AAAAA” and the anchor “to BBBBB”. To release.

Finally, in step W14, step W
The display data generated in step 13 is displayed on the display device 22 via the display unit 36, and the process returns to step W1.

[0050]

As described above, according to the present invention, even if the access page attribute is not specified in the anchor tag, the shortcut key is automatically assigned and the link using the shortcut key is assigned. By providing the jump operation means, it is possible to improve the operability of Web browsing in an information terminal that does not have a pointing device such as a mouse.
